Medical Discovery News is a weekly radio show produced by Dr. David Niesel from The University of Texas Medical Branch and Dr. Norbert Herzog from the Frank J. Netter School of Medicine Quinnipiac University to help people understand the excitement and importance of advances in biomedical science which is the future of medicine. Each episode is designed to stimulate listeners to think question and appreciate how science affects their health as well as that of the rest of the world. We bridge the world of medical discovery and history for people to better their lives.
You are likely to have heard Americans are getting fatter. Eating fast and processed foods and a sedentary lifestyle are likely contributors. Today almost of Americans are overweight and this is a public health disaster. Officials in New York City sounded the alarm and intervened by banning trans fats but that is hardly enough. It is recognized that there are many other causes. By definition you are considered obese if your body mass index is over . Another prevalent health issue in the US is problems with sleeping. Almost million people have sleep apnea and about one third of Americans are not getting enough sleep. There is also a high association between sleep disorders and being overweight. But did you know that almost of overweight adults report sleep problems A study followed women for years and found that those sleeping less than hours a night had a greater chance of gaining lbs or more over that time. How is that for a correlation
Sleep deprivation has many effects including increasing irritability memory issues reduced immune function risk of heart disease diabetes and obesity. The connection between obesity and sleep has been reported many times. Predictably sleepy people are apt to not exercise regularly. Reduced activity with even consistent caloric intake can pile on the pounds. On top of this our bodies own metabolism works against us.
Hormonal changes are induced during sleep deprivation. The so called hunger hormones leptin and ghrelin are appetite stimulating hormones whose levels are altered in sleepdeprived individuals. So when you are tired the signals are interpreted as being hungry and you eat It turns out that hunger and sleep induced fatigue alters the physiology of humans similarly.
Our brains also make a chemical called endocannabinoid arachidonoylglycerol or AG. You might have guessed it is chemically related to the active chemical in marijuana and has some of the same effects. It is likely that the cause of the hunger arising from limited sleep is similar to the munchies from smoking pot. AG is associated with pleasure and appetite and is elevated in those that are sleep deprived stimulating the brains reward system. Researchers found that restricting sleep from eight and one half to four and one half hours led to the consumption of an extra calories in the form of fatty rewarding snacks during the evening. These results provide obvious implications for weight gain from sleep deprivation. Hunger correlates with AG levels observed in the blood. Sleep deprived individuals had levels of AG that were one third higher than those with a full nights sleep. For those sleeping normally AG builds during the day peaking in the early afternoon while those with limited sleep maintained high levels of AG well into the evening. Therefore AG maybe a new target for therapy to prevent weight gain.
There is also hope in taking advantage of this connection between weight and sleep behavior. If you can achieve more normal sleep this may help you with weight loss and vice versa.

We have featured several episodes about the Iceman tzi who lived years ago but whose remains were found by hikers in the Italian Alps in . Studies of his mummified remains have revealed much about his life during the Copper Age between and BCE. Now we report not on tzi himself but on his stomach bacteria which tells us about his life and the history of human geography.
Heliobacter pylori or H. pylori found in tzis stomach infects two thirds of the worlds population. This bacterium is thought to have become associated with humans at least years ago. As humans spread to different locations around the world and often formed isolated communities different strains of H. pylori arose. By analyzing the genetic information of these bacteria in different human populations scientists gain insight into how these ancient humans might have traveled and intermingled. These bacteria are only passed between people through intimate contact therefore its distribution is limited to the isolated population. So looking at the genome of tzis H. Pylori we can get an idea of the people he had interacted with. It was a difficult task to separate out the genetic information from a single type of bacteria among all the genetic information in the Icemans body. Scientists managed to pull out his H. pylori DNA bit by bit and compared its sequences to those of modern strains. The modern European H. pylori strain is actually a combination of an Asian and an African strain meaning that sometime in the past those two populations came together but where and when is unknown. So tzis H. pylori could tell us which strains existed in Europeans during the Copper Age.
The DNA sequence of tzis H. pylori revealed that it was almost purely Asia in origin despite his never having left Southern Europe. Only . of its genetic information was of African origin suggesting it was likely in Europe for quite some time. This data suggests that there were not waves of migration from Africa but it is unclear who brought the bacteria from Africa into Europe. It is theorized that the mixing to create the modern stain of H. pylori had to have occurred after the Copper Age which is much later than previously estimated. The speculation is that the African strain came to Europe via the Middle East but earlier than years ago. It may have been the first farmers who brought the agricultural revolution from the Middle East to Europe and brought their strain of H. pylori as well. Of course these are conclusions based on the sequence of H. pylori obtained from a single individual. Scientists will need sequences from many more ancient peoples to understand how they moved around and intermingled. Our ability to isolate and sequence the DNA of ancient mummies and their microbiomes from around the world will provide much more insight into the human populations and how they migrated. Who would have thought that we could use a bacterium to further our understanding of ancient human migration.

Every now and then things go right really really right. In an immunotherapy clinical trial of the leukemia patients went into sustained remissions which is a whopping percent success rate
Acute lymphocytic leukemia or ALL is a cancer that arises in the bone marrow the soft center of flat bones. In the bone marrow blood stem cells give rise to all blood cells. ALL arises from the cells that become lymphocytes a type of white blood cell. Acute in the name means that it can progress quickly and if not treated can be fatal within a few months. If the ALL cancer cells occupy more than of the bone marrow the disease is called leukemia.
Lymphocytes are a major part of the immune system found in lymphoid tissues as well as circulating in the blood. Lymphocytes come from immature cells called lymphoblasts and mature into main types of cells B cells and T cells. T cells serve a variety of functions from orchestrating the immune response to an invader to killing infected cells or killing microbes directly. ALL does not form masses but rather takes over the bone marrow and spreads to the lymph nodes spleen and liver. The prognosis for ALL depends on age the younger you are the better. Prognosis also depends on the numbers of cancer cells abnormalities the tumor DNA and how quickly the leukemia responds to treatment. Treatment usually involves chemotherapy targeted therapy or stem cell transplants and can last about years. About percent of adult patients have complete remissions but about half relapse giving an overall cure rate of about percent.
The study with the percent response rate involved patients whose other treatments had failed and they had only a few months to live. Scientists isolated what are called killer Tcells from the patients. These cells can attack and kill cancers cells. The researchers engineered these T cells to target the patients ALL cells. They genetically engineered the T cells with synthetic molecules called chimeric antigen receptors or CARs that enable them to target and destroy tumor cells. Cells were expanded and then infused into the patients. More than ninety percent of the patients achieved remission of their cancers within days however developed a severe immune response that required time in intensive care and an additional patients died. Adjusting T cell dosages infused eliminated these unwanted effects. Unlike other treatments the T cells will continue to grow and provide ongoing protection. These results from patients with such advanced stages of ALL is impressive. This is a relatively new type of approach called immunotherapy by which our bodys own immune system is programmed to attack a cancer. An advantage of this type of therapy is that it is likely to have fewer side effects and would have long lasting cancerkilling abilities should cancer cells arise later. For those patients that relapse or for whom conventional treatments fail this approach provides new hope. So stay tuned we will undoubtedly be hearing much more about immunotherapy in the future and the future looks pretty good already.

Since ancient times compounds containing mercury have been used in the treatment of skin diseases and other ailments. However mercury toxicity was not fully appreciated until March when two British ships the HMS Triumph and HMS Phipps came to the rescue of a Spanish ship that had been damaged in a hurricane. They rescued the crews and transferred the valuable cargo of mercury. Within weeks the crews began to experience the effects of mercury poisoning eventually many were hospitalized and some died.
Mercury was known to ancient peoples and was even found adorning a th century BCE ceremonial cup in an Egyptian tomb. Aristotle authored the earliest record of what he called fluid silver or quicksilver in the th Century BCE. Mercuric chloride calomel was used as an antiseptic to kill bacteria while mercuric sulfide is used to make the bright red vermillion paint. Mercury was also commonly used in batteries fluorescent lights thermometers barometers and felt production leading to dementia in those workers and the phrase mad hatters coined by Lewis Carroll in Alice in Wonderland. Mercury has been used to extract gold and silver by a process of amalgamation. The Spanish ship was transporting mercury to South America for the extraction of silver. On March th some of the mercury was transferred into the sloop HMS Phipps. The cargo had been saturated with water leading to rotting containers with several tons of mercury leaking into the lower decks and holds of both ships.
Mercury quickly contaminated everything on the lower decks. Within weeks mercury poisoning appeared among the crews. Symptoms of mercury poisoning were excessive saliva secretion mouth ulcerations and partial paralysis as well as lung and bowel complaints. At an estimated temperature below decks of degrees F the saturation point of mercury would have been times the maximum allowable concentration. Those with the highest exposure some of whom later died suffered from dramatic swelling of their heads and tongues lost their teeth and suffered from gangrene of the face and tongue. By midApril men one third of the crew showed signs of mercury poisoning. On April nd the men were transferred to hospital ships and the Triumph was inspected by four fleet surgeons. The Triumph was a large gun ship of the line. The very different structure of the sloop HMS Phipps lessened the impact of mercury on board though some of her sailors were also affected. The Triumph was cleaned and returned to service in June only to have fresh cases of mercury poisoning appear. By June th she was ordered to sail home to England which took days and despite numerous precautions additional men became ill but the symptoms were not as severe. The Triumph was emptied and little is known about her fate other than she became a quarantine ship before being broken up in . Though poisoning with mercury was known accidental poisoning by mercury vapor was rare and the incident on the Triumph is unique in the history of toxicology. It gave everyone a fuller appreciation for the dangers of mercury poisoning.

Parents worry if their children are getting a good diet that will allow them to grow up healthy and strong. It came as somewhat of a shock when parents of a toddler in Spain were told their child was suffering from scurvy a lack of vitamin C. After all wasnt scurvy what plagued sailors of old It could not be the case in modern Spain.
The pregnancy was uneventful and his birth weight was a respectable . pounds. He received the recommended vaccinations and for the first two and a half months of life was fed a cows milk based formula in lieu of human breast milk. He developed a rash and his diet was changed to an almond based formula. Beginning at about six months the mother tried to introduce pureed fruits and vegetables but they were refused. From two and a half to months the toddler only ate a mixture of almond milk and other grains with some added probiotics. At seven months he could sit with support but one month later he was less stable sitting. Though he continued to grow longer his weight gain plateaued and declined by months. He appeared fairly healthy but irritable and could not support his legs on a solid surface and cried when his legs were moved passively.
Leg Xrays showed signs of bone density loss called osteopenia thinning of bone and other features linked with changes associated with scurvy as well as a fracture of his right leg. He also had numerous abnormalities in his blood work including extraordinary low levels of vitamins C and D. These results along with his nutritional history pointed to a diagnosis of infantile scurvy.
Scurvy is caused by a lack of vitamin C in the diet and results in defects in the protein collagen which is found in bones muscles skin and tendons which provides structural support and strength. Vitamin C is also required for the growth and maintenance of bones. Scurvy leads to general weakness anemia gum disease and hemorrhages in the skin. Humans cannot make vitamin C therefore it must be acquired in the diet from fruits vegetables or vitamin supplements. Bone growth is particularly rapid during the first two years of life then continues in spurts until the late teens or early twenties. The fact that this child was not receiving sufficient amounts of vitamin C and D meant that his bones could not form properly and became thin and brittle. An analysis of the toddlers diet revealed that his diet was also low in calcium iron and zinc. Plant based infant formulas have become increasingly popular in developed countries in recent years. The toddler was placed on vitamin C replacement therapy with mgday. In the next three months his condition rapidly improved with less leg pain and fewer radiological findings in his bones. The vitamin C levels returned to normal and he started to walk much to his parents relief. This could have been avoided by breast feeding which carries with it many other benefits.

There are many pros and cons for a woman when choosing either a caesarian Csection or natural birth. Sometimes medical circumstances push the mother and her physician to a Csection. For example when a mothers life is threatened or complications such as high blood pressure or gestational diabetes develop this decision is favored. Mothers can also choose Csection if they want to plan the delivery or because of a previous Csection. Overall about one third of births in the US are by Csection. Many studies have addressed Csection birth influences on the babys health and development. Reports have linked Csection births to later obesity Type I diabetes in adolescents and early breathing difficulties and even asthma.
Scientists have been asking what is different during Csection birth that could explain these health alterations in the developing individual. We know that natural childbirth is stressful to the baby which is different from low stress surgical removal from the uterus during Csection. Previous studies have shown that the methylation patterns in the DNA of infants born by natural versus Csection are distinctly different. These changes altered regions of the genome that determine immune function our ability to resist disease and protect our bodies. Recently a study compared the microbiome of babies born by Csection and natural birth. And not surprisingly they are different. Our microbiome is the total population of microbes that live in us and on us and outnumber our own cells by more than to times. It makes you ask who is hosting who We derive many benefits from our microbial cohabitants. They provide a first line of defense against invading diseasecausing microbes contributing to something called our innate immunity. They also have been shown to broadly affect our metabolism linked to the onset of diabetes and can even affect our brains by influencing emotion and behavior.
An infant born vaginally is exposed to the bacterial populations in the birth canal the vaginal microbiome. Babies born by Csection are not exposed to these microbial communities and acquire a microbiome that is more like the bacteria present on the mothers skin.
In a recent study eighteen expectant mothers who were planning to have Csection deliveries participated. Four mothers agreed to have their babies exposed to their vaginal microbiome after birth. To accomplish this exposure to the vaginal microbiome a sterile gauze pad was placed in the mothers vagina for one hour and used to rub the babys mouth face and body transferring the microbiome populations to the baby. The babies bacterial populations on their skin mouth arm foot and anus area were closely monitored for their first thirty days of life. The results showed that the swabbed babies developed microbiomes that closely resembled those of vaginally born babies rather than the one of babies born by Csection and not exposed to the vaginal microbiome.
It will be interesting to follow these babies and those from future studies to see if this exposure to the vaginal microbiome alters their health outcomes.

By Drs. David Niesel and Norbert Herzog An international trial was recently published revealing the outcomes for patients with relapsingremitting multiple sclerosis who received blood stem cell transplantation. Excitingly these stem cell transplants were associated with substantial improvements in neurological symptoms and other clinical outcomes of MS. While these are preliminary findings they are nonetheless exciting. MS is a disease in which a persons own immune system attacks the myelin sheath that covers nerves. This reduces the ability of nerves in your brain to efficiently communicate with your muscles. Myelin is a wrapping made of lipids or fats and proteins that serve to insulate and protect nerves much like the plastic covering of electrical wires. Myelin also serves to greatly increase the speed by which nerves signals are transmitted. Myelin is present in both the central nervous system and the peripheral nervous system. In MS only the myelin in the CNS is affected. The damage in MS can also lead to damage of the nerves eventually leading to scarring and issues with nerve conduction. If this process is not stopped it can lead to permanent neurodegeneration.
Symptoms of MS vary for each individual and over time. Symptoms can include fatigue numbness or tingling weakness dizziness pain difficulties walking spasticity vision and bladder problems among many others. These primary symptoms can advance to more severe secondary and tertiary symptoms. This is an incurable disease that can leave a person unable to walk and perform other routine tasks.
Current treatments include strategies to manage relapses or attacks and the symptoms. So the thought was if the immune system in an MS patient could be rebooted to the state before it began to attack the myelin then the symptoms of MS would disappear. This technology has been used for many years in the treatment of blood cancers. The treatment is called autologous hematopoietic stem cell transplant. The rogue immune system is first destroyed using chemotherapy. The immune system is then replaced using stem cells from the patients own blood. These cells are very immature and have not yet learned to attack the myelin and therefore could still protect these patients from infections but no longer damage the myelin and stop and perhaps even reverse the effects of MS. Indeed several MS patients who received transplants have gone from being wheel chair bound to once again walking and regaining other functions of normal living. For some patients the improvements have persisted for at least four years another encouraging fact. Right now physicians categorize these recoveries from MS as dormant MS and it remains to be seen if they are permanent.
Of course cost to benefit analysis cannot be ignored. The approximate onetime cost of a transplant is about equal to the cost of care for some MS patients per year. That makes the math easy if this works and is a cure the cost is well worth it. Even if these transplants cannot be used to treat all forms of MS at least some of MS patients have hope of a permanent solution to their symptoms.

By Drs. David Niesel and Norbert Herzog Medical Discovery News In the past several years we have heard a lot about infectious microbes threatening the public health of all Americans. Some of the names of these agents seemed foreign at first but are familiar now Ebola MERS and Zika. But are these really new viruses causing disease No we have known about these microbes as disease threats in Africa the Middle East and Central and South America for some time we have known about Zika since the s. A better way to describe these viruses is as emerging infectious diseases viruses that used to be limited to small geographic foreign areas that now threaten to spread across the globe. And lets not forget the microbes that have plagued us for years like the flu. We are being assaulted from all directions.
Standing between us and infectious microbes is our public health infrastructure that protects all Americans from infectious disease threats. A recent report by the Trust for Americas Health and the Robert Wood Johnson Foundation raises concerns for our ability to prevent detect diagnose respond and prevent infectious diseases outbreaks. They report more than half of US states scored or lower out of on key indicators related to managing infectious diseases. Some of these key indicators are public health funding flu vaccination rates HIV surveillance childhood immunization rates food safety central line associated bloodstream hospitalacquired infections and the staffing and training activities of our state public health labs.
Here are some examples of the concerns raised by the report. For central line associated bloodstream infections only states reduced the standard infection rate associated with this procedure. Only states met the target for childhood immunization. Eleven states failed to meet national performance standards for testing for the food illness caused by E. coli O. Finally states failed to increase or even maintain public health funding over the past two years.
The scorecard in this report rates each state by how many of the key public health indicators are met. No state met every recommended indicator but those at the top were Delaware Kentucky Maine New York and Virginia who met of the criteria. At the bottom meeting just of criteria were Idaho Utah Kansas Michigan Ohio Oklahoma and Oregon. In total states failed to reach the midpoint achieving of the indicators. This is shocking and could represent a prescription for future public health disasters. Go to www.healthyamericans.org to view the scorecard and see how your state is doing.
This extensive and illuminating report makes numerous recommendations to improve our public health preparedness to handle these infectious disease threats.
Remember most infectious diseases are preventable. The reality remains that it will be less costly to take steps now to prevent detect and limit infectious diseases than to treat people after acquiring one especially after a major outbreak. The old adage by Ben Franklin an ounce of prevention is worth a pound of cure comes into play once again.

Bacteria and viruses live on and in us as part of our normal flora or microbiome. In fact microbes outnumber our own cells by to to . But there are even more creatures that we share our lives with parasites and vermin.
Studies of these creatures are actually quite revealing about human evolution and migration. For example all of us harbor a mite that lives in the hair follicles on our faces called Demodex folliculorum. They are tubular in shape with iddy biddy legs and live deep in our follicles. Somewhere between of people are colonized with them and this infestation is only rarely associated with a disease. Scientists collected mites from the faces people of different origins most from the US. They sequenced mitochondrial DNA from these mites. Since these mites are only shared between sexual partners or close family members they can help determine where people came from. People from different continents harbor different varieties of mites on their faces. The type of mites that people carry remain the same even long after they have traveled to another geographical region and even generations later. As ancient humans left Africa and moved to other areas of the earth and became isolated populations mites coevolved along with them. So the type of mite you carry can help to identify your origins.
Another group of scientists are studying the tapeworms that infest mammals as a way to determine when ancient humans began to eat meat. It has been assumed that humans acquired tapeworms when they domesticated cows and pigs some years ago and consumed undercooked meat which allowed the tapeworms to survive. However the three types of tapeworm that currently infect humans are most like those that live in lions and hyenas. So humans acquired these parasites long before the domestication of mammals when they ate the same animals consumed by lions and hyenas. That moves ancient humans carnivorous origins back to the Pliocene and Pleistocene epochs between . and . million years ago.
Getting evidence about when our human ancestors lost their fur and began wearing clothes made from animal furs would have been impossible except for the lowly louse. Some million years ago our human ancestors acquired head lice from chimpanzees. Then about million years ago ancient humans were colonized with pubic lice that came from gorillas suggesting that by that time the hair of the head and of groin were no longer connected by fur making them separate environments. Head lice genetics reveals evidence of a population expansion out of Africa about years ago which mirrors human migration. Though modern humans have a relatively limited mitochondrial DNA variability going back to a common ancestor within years lice have very different lineages that converge on a common ancestor million years ago. So they have been around a great deal longer than their human hosts. Analysis of the DNA from pubic lice revealed that they diverged from head lice between and years ago and clothing is likely to have helped to isolate the two populations. We are unlikely to ever know for sure if this estimate is accurate but it is interesting to speculate when these features of our lives arose. So we have been making fashion statements at least that long.
The multitude of organisms that live on us and in us have been shown to be important in keeping us healthy and defending us against the many pathogens to which we are exposed. They also are helping us learn more about ourselves our origins and our travels.

When surgeons remove a cancerous tumor their goal is to remove all of it. But determining which cells are cancerous and which are healthy is tough. A pathologists job is to quickly examine the excised tissue to determine whether all of the tumor has been removed. Sometimes despite a medical teams best efforts later MRI and CT scans reveal that cancer cells have been left along the margins. As a solution scientists are looking for ways to light up cancer cells so that surgeons can see them more easily during an operation.
Scientists at the Massachusetts Institute of Technology invented a blue fluorescent dye called LUM. They injected the dye into breast cancer patients at the Duke University School of Medicine before surgery. The doctors were able to successfully remove the tumors in each of these women and none of them experienced any adverse reactions.
The dye LUM works because it is cut by a protease enzyme called cathepsins. In normal cells cathepsins job is to cut and degrade proteins. However in many tumors cathepsins are made in higher amounts and are sometimes secreted by cells. Once secreted these cathepsins rest on the surface of cell and then serve as a marker to identify tumor cells.
These extra cathepsins also begin to digest the extracellular matrix or ECM. The ECM is a mesh of molecules that holds cells in place. Once the ECM is gone cells lose their ability to stay in one place and start migrating into the surrounding tissue a hallmark behavior of cancer cells. In fact one of stages of cancer is called metastasis which happens when cancer spreads to other parts of the body.
When these extra cathepsins on tumor cells cut LUM the dye causes them to light up blue. A surgeon can see this blue luminescence when a handheld imaging device is held over the area. In experiments with mice the tumor tissue with LUM glowed five times more brightly than normal tissue making even small amounts of tumor easy to spot.
About percent of cancer surgeries require a second surgery. This is because the tumor removal did not result in sufficient margins around the tumor free of cancer cells. Since the goal of every cancer surgery is to remove all of the tumor LUM could help ensure this. It is the first proteaseactivated dye for cancer detection during surgery that has been tested for safety and effectiveness in humans. So far it seems to be working as everyone had hoped. The goal is to test the dye in more patients and at additional hospitals to determine its safety and assess its ability to aid in the removal of all tumor tissue on a larger scale. The scientists who invented LUM started a company called Lumicell. They hope to save people from the pain and cost of extra surgeries and potentially the amount of radiation therapy used to ensure that all tumor cells were eliminated the first time.

Some who use kratom to ease their withdrawal symptoms from heroin addiction are discovering that this is also an addictive drug that can reignite the cravings for the heroin they are trying hard to conquer. The use of kratom as a painkiller or to treat depression or for the mild high it provides is gaining in popularity but its potential dangers are not well understood.
Kratom is legal in most states and is sold under a variety of names. It is available in powdered form at head shops convenience stores and online. There are even bars that sell beverages made with kratom in Colorado Florida New York and North Carolina. Reports suggest that million Americans have purchased kratom online for the management of chronic pain or to mitigate opioid withdrawal.
The U.S. Food and Drug Administration banned the importation of kratom in due to the strong suspicion that it was harmful but the laws concerning the drug are so bizarre that it was sold legally in Chicago at the same time. Although the FDA considers kratom to be a somewhat safe dietary ingredient the U.S. Drug Enforcement Administration lists it as a drug of concern but not a controlled substance. Some states have banned it and the Army forbids its use by soldiers.
Kratom comes from a tropical tree in the coffee family Mitragyna speciosa which is indigenous to Southeast Asia. The name kratom comes from the term for the tree and the preparation of its leaves in Thailand. The use of kratom has been outlawed there although now there is a movement to legalize it. Traditionally kratom leaves are chewed or used to brew tea. Low doses of it have cocainelike stimulatory effects and are used to overcome fatigue. Higher doses have opiumlike sedative effects used in traditional medicines as a substitute for opium. It is also used to treat pain diarrhea coughs and premature ejaculation. The symptoms of the drug appear minutes after consumption and can last for up to an hour. Side effects of longterm kratom use include weight loss tiredness constipation and hyperpigmentation of the cheeks.
The active ingredients in kratom bind to the same cellular receptors as heroin or morphine but it also binds to two other receptors accounting for its different effects. And like heroin or morphine kratom produces dependence. Withdrawal symptoms are relatively mild but include craving weakness lethargy anxiety restlessness runny nose muscle pain nausea sweating jerky movements of limbs tremors sleep disturbances and hallucinations. It looks like taking kratom comes with a price of its own.
Since some opioid addicts use kratom to overcome their addiction advocates of it state that it is useful for reducing dependence on more dangerous opiates and has the advantage of not being detected by drug tests for now. But some former opiate addicts report becoming addicted to kratom and ending up back in rehabilitation. It is both a way of overcoming addiction and an addiction itself.
The scientific study of kratom requires more research into its physiological effects. Its one of many drugs wading through a murky legal environment and challenging law enforcements ability to keep people safe.

Unless you are totally cut off from the news you have heard about the Zika virus. Maybe more than you want because this is a scary virus especially if you are pregnant. We have known about this virus for some time. It was first isolated in and has been pretty much of a scientific curiosity until recently. And then seemly we look up and there is a fullblown outbreak in Brazil that is marching steadily across South and Central America and the Caribbean. But also it has breached American shores with infected individuals now reported in several American cities. These Zika infections have originated from travelers to affected areas or those in close contact with those that have traveled in that region. Person to person spread has been shown after sexual contact and the virus can be found in infected individuals in semen salvia and in urine.
The world is focused on this virus because of its devastating effects on the most helpless among us babies. When a pregnant women becomes infected there is a link between Zika infection and her baby being born with a small head and brain. This is called microcephaly. As you can imagine with an infection affecting the brain microcephaly leads to developmental issues with the baby and many do not survive beyond adolescence.
While microcephaly is obvious at birth this could be the tip of the iceberg in terms of the number of children with neurological problems that will be revealed as they grow older. Adults can be infected resulting in neurological consequences also. In infected adults there is a times higher chance of developing GuillainBarre syndrome which results the immune system attacking nerves. GBS can be mild for some it can last for months and in of cases GBS can lead to death.
Recent studies may have started to reveal how the Zika virus causes brain damage leading to the symptoms observed in babies and others. It has been shown that Zika interacts with neuroprogentior cells which are immature cells on the path to becoming glia cells or neurons two of the most important cells in the brain. In experiments percent of the neuroprogenitor cells became infected with the Zika virus and went on to produce more virus. Here is the punch line this means that two of the major cell types in the brain are susceptible to Zika infection and those infected cells are eventually killed by the virus or slowed in growth significantly. This could be the smoking gun that explains how Zika can damage the brain.
Many adults who become infected with the Zika virus dont experience symptoms and its usually mild for those that do such as joint pain fatigue and low fever which usually last two to seven days. However women who are pregnant or want to become pregnant in the near future should avoid Zikainfected areas and men whove traveled to Zikainfected area should refrain from unprotected sex. Currently there are not any treatments or vaccines for Zika so hang on we are in for a bumpy ride this summer and beyond.

The future of treating genetic diseases may lie within the emerging field of molecular surgery. It may seem impossible to imagine doing surgery on such a micro level but the development of a molecular technique called genome editing can be used to correct genetic defects within cells. We are always looking for new weapons in the fight against genetic diseases which can have devastating effects. We inherit our genes from our parents and each of us has variations in the sequence of our genes that make us unique. However mutations as small as a single base these are A T C G in your DNA can lead to lifealtering diseases such as sickle cell anemia or cystic fibrosis.
In laboratories around the world new molecular tools are being developed that can be used to correct such genetic mutations and therefore provide a cure for the diseases they cause. Using molecular surgery doctors could theoretically fix the genetic defect.
A recently developed molecular technique that enables scientists to edit genes is called CRISPRCas. CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats. These are short repetitive sequences in our genomic DNA that are spread throughout the genome. Cas is a protein that acts as molecular scissors.
This works by creating a short piece of RNA a genetic molecule like DNA that targets a specific gene in the lab. Then the RNA and the Cas protein are introduced into cells where the RNA provides a guide to the gene to be modified then acts as a target for the cutting action of the Cas protein. This can be used to remove or more importantly in this case to replace a defective gene with a functioning one. So far experiments in the laboratory show CRISPRCas is able to repair the genetic mutation that causes sickle cell anemia and also cystic fibrosis mutations. In addition it has been used to prevent and slow the spread of HIV. This technology also has the capability to correct multiple mutations simultaneously which will be crucial to curing diseases that arise by more than one genetic mutation. The next step will be clinical trials to evaluate CRISPRCass potential to correct mutations and treat disease directly in humans. For some diseases correcting the mutation in even half of the affected cells could prevent symptoms and essentially cure the disease.
As with any technology that provides the ability to change the human genome scientists must consider the ethics of molecular surgery seriously. For example could parents alter an embryo or childs genes so they are more athletic or have a specific eye color The range of options when changing genes is almost limitless and profound. To that end scientists from around the world have already met to start developing a system of guidelines for this type of research. It will take our scientists medical ethicists and citizens to decide the boundaries of this powerful and far reaching technology.
CRISPRCas and other methods of molecular surgery have a profound potential to cure diseases and could alter our future health in ways we can only imagine.

Have you noticed in the past few years we seem to be continuously assaulted by microbial menaces Some years back it was SARS which set off a global panic. People were screened for fevers at many major international airports. Then came the West Nile virus which started from a single case in New York and in a matter of years marched across the U.S. Who can forget the avian flu or swine flu which happened around the same time More recently the MERS virus has emerged with outbreaks in the Arabian Peninsula and then whole villages in Korea. We are just now reaching the end of the devastating Ebola outbreak in West Africa. Even if youre not an alarmist its hard to ignore the threat of these new microbial menaces.
The latest is one that we are beginning to know well is Zika. While it sounds like the name of a modern Scandinavian rock band this virus was first isolated in in Uganda. It emerged in the Pacific Islands before it spread to Brazil and its rapidly spreading through two dozen countries in the Caribbean Central America and South America. Now cases of Zika have been confirmed in the U.S. and Europe in people who have recently traveled to an outbreak area where the virus is spreading. Individuals can also become infected after direct contact with someone who has just returned from one of these areas. What makes public health officials in America highly concerned about this virus is that it is spread by mosquitoes called Aedes aegypti and Aedes albopictus that are common in the eastern and southeastern United States.
There is accumulating evidence that Zika infection in pregnant women leads to birth defects most notably microcephaly. This means Zika could potentially threaten thousands of unborn fetuses. The images of the babies afflicted by this disorder which causes abnormally small head sizes are heartbreaking.
But the damage to babies born to a mother who was infected is not limited to this highly visible birth defect. There is emerging evidence that Zika can cause other neurological problems. In a recent study of fetuses from women testing positive for Zika babies showed a range of neurological problems. Seven had lesions in the central nervous system five had issues with brain development and an additional two were stillborn. The neurological lesions are devastating and lead to significant developmental issues. Mothers who become infected with Zika immediately become part of a highrisk pregnancy group. Evidence now suggests that Zika infection is associated with neurological disorders in children and adults as well.
Most adults who become infected with the Zika virus dont experience symptoms and its usually mild for those that do. They have symptoms such as joint pain fatigue and low fever which usually last two to seven days. Some adults however can develop GuillainBarr syndrome an autoimmune disorder. However women who are pregnant or want to become pregnant in the near future should avoid Zikainfected areas and men whove traveled to Zikainfected areas should refrain from unprotected sex for at least two months since the virus can be transmitted sexually. Currently there are not any treatments or vaccines for Zika so hang on we are in for a bumpy ride this summer and beyond.

By Drs. David Niesel and Norbert Herzog Medical Discovery News When you get sick how do you know when its safe to come into contact with other people without spreading the infection For many infections such as influenza you get sick one to four days after being exposed and you can spread the virus for an additional five to seven days after becoming sick. Now consider the importance of that timeline when it comes to a deadly virus like Ebola. The Ebola outbreak in West Africa has been declared over but we may need to rethink that conclusion.
Ebola causes an acute illness that has a high mortality rate. People become infected many die up to percent but some recover. It was thought that once you survived the infection you could not infect other people and you were immune against the virus in the future. However we have learned that once you have become infected with the Ebola virus you are not free of the virus when your symptoms disappear. The virus is not necessarily gone from your body and can reemerge. Lately a new twist in this news has significant public health implications. A Liberian woman contracted Ebola from a male sex partner who was an Ebola survivor. The couple had sex nine months after the male was first infected with Ebola and more than days after he was determined to be free of infection. Based on this clearance the couple had unprotected sex at a point beyond the threemonth waiting period currently recommended by health authorities. Molecular analysis and sequencing of the virus showed that the virus did most likely come from her male partner and not from another source. Ironically she became infected just days after the West African nation of Liberia was declared Ebolafree. Unfortunately the woman did not survive the infection. The recommended waiting period for unprotected sex has now been extended to six months after recovery.
Recent studies found males who recovered from an Ebola infection still had the virus in their semen. No reactivation of this infection from this source have been reported yet. In additional studies semen samples from almost Ebola survivors were tested for the virus. Half the men carried the virus for up to six months and a quarter carried it for up to nine months. If there is good news it appears that sexual transmission of Ebola is rare. Fewer than cases of sexual transmission were observed from the male survivors. Still the U.S. Centers for Disease Control has recommended the testing of male survivors until two consecutive tests of semen are negative and more is understood about sexual transmission. Safe sex practices should be used during this period.
Research on Ebola has intensified since the outbreak. Now there are promising new vaccines in field and laboratory testing offering real hope that epidemics like this one will not happen again.

Experts in Egyptology and snakes collaborated to determine if the story of the Egyptian Cobra or asp could have killed Cleopatra and her two attendants. The first issue is that most cobras would have been too big to smuggle into a room in a basket which is part of the legend. Cobras are usually five to six feet in size but can grow to eight feet. The second issue is whether the same snake could kill three people with consecutive bites. The snake experts claim it would be very unlikely that a cobra could be induced to bite two or three people in quick succession. Snakes are capable of biting defensively without injecting venom and in fact most bites from a cobra are dry bites when no venom is injected so the snake can conserve it for hunting and protection. In addition it appears that cobras can control the amount of venom delivered depending on the threat they face. However cobras do not exhaust their store of venom even after several strikes.
Cobra bites can be fatal if not treated with antivenom or an artificial respirator until the paralysis of the diaphragm muscle wears off. The venom includes a neurotoxin that causes problems with swallowing vision speaking muscle weakness difficulty breathing respiratory failure vomiting and abdominal pain. Other symptoms include necrosis of tissue in and around the bite site as well as anticoagulation. It is a slow and very painful death if untreated nothing like the quick and painless death the Egyptian queen would have preferred. It seems likely that William Shakespeare and Elizabeth Taylor have framed the snake and that the real Cleopatra committed suicide by some other means such as poison.

Secondhand smoke from tobacco products is a complex mixture of thousands of different chemicals. Hundreds of these chemicals are toxic and at least are carcinogenic. Even brief exposure to these chemicals is not considered safe. It can lead to molecular changes that cause cancer and changes in the cells that line blood vessels and alter platelets in the blood which can increase the chances of a heart attack. An estimated . million nonsmoking Americans have died from exposure to secondhand smoke since the mids. Smoking during pregnancy is especially deadly leading to or more infant deaths annually.
We already know that secondhand smoke can have serious and longterm effects on a childs health. Exposed children are known to get sick more frequently. Children are more likely to experience wheezing and coughing and those with asthma are subject to more frequent and severe attacks which can become lifethreatening. They show a reduction in lung growth during their development and experience more bronchitis pneumonia and other respiratory and ear infections. Secondhand smoke can also lead to sudden infant death syndrome in children.
A Swedish study published last year studied how exposure to secondhand smoke in children can lead to increased risks of sensitization to food allergens and the development of food allergies. The common foods children are allergic to include cows milk eggs wheat peanuts and fish. This large study enrolled more than children who were followed from birth until they were years old. The study used periodic questionnaires to track secondhand smoke exposure and symptoms of allergic disease. This study did not include children who were exposed during pregnancy. This made it easy to determine the effects of secondhand smoke.
Results from this study clearly showed that secondhand smoke exposure resulted in increased sensitization of children starting at age four. This sensitization to food allergens persisted into adolescence. Food allergies can have a tremendous impact on childrens lives and the health care costs associated with managing this longterm health concern are significant.
How can you protect children from the health effects of secondhand smoke First do not smoke around your children where you live or in your car. Second do not permit anyone else to do so either. Third choose babysitters daycares and schools that are smoke free. If you suspect your child is suffering any health effects due to secondhand smoke food allergens or otherwise see your pediatrician.
It sounds logical but consider the many smokers who come in contact with a child throughout their development and the complications of creating a smokefree environment.

We all need light to see but now a new gene therapy is restoring sight to those with vision problems by figuratively lighting up their vision.
Your vision cannot process anything without light. When light comes in contact with the cornea the transparent outer layer of the eye it bends the rays that pass through the pupil the dark circle in the center of the eye. The purpose of the iris the colored part of the eye is to make the pupil bigger or smaller to let in enough but not too much light like a camera.
Behind the pupil is a lens that focuses the light on the retina in the back of the eye. The retina is composed of millions of cells some called rods and cones for their distinctive shapes whose purpose is to sense light. The cones provide sharp vision fine details and clear colors. The rods provide the peripheral vision vision in dim light and the ability to see motion.
The retina converts the light entering the eye into electrical impulses and sends those to the brain through the optic nerve. The brain then deciphers the electrical signals into an image we can process.
Many different diseases can affect sight from concussions and other brain injuries to diabetes. Lifestyle choices such as how much or how little your eyes are exposed to the sun also affect eye health.
Of course our genes can play a role in how strong or poor sight is as well. Take for example retinal pigmentosa RP a group of rare genetic disorders where certain genes that encode instructions for proteins are mutated. When these proteins malfunction the rods and cones in the retina are slowly lost and with them the ability to detect light. Scientists created a gene therapy that can restore the loss of light receiving cells in those with RP by targeting a gene called RPE.
The protein this gene encodes is involved in the visual cycle which is triggered by light entering the eye. The cycle begins when a molecule similar to vitamin A is converted to another molecule called alltrans retinal. This conversion tells the eye to send electrical signals to the brain but for us to continue to see the RPE protein has to convert the alltrans retinal back into the vitaminA like molecule. Then it is ready to go again.
This cycle does not happen when the protein malfunctions so the new therapy targets the protein by using an engineered virus called AAV. Its engineered to carry the normal form of the RPE gene. The engineered viruses are surgically introduced into the eye where they infect cells and begin making normal RPE proteins to correct the defect. In a clinical trial involving people all showed improved sensitivity to light. Some nearly blind patients had restored sight even three years after the therapy.
The treatment may be approved this year but many people wont be able to afford the cost. Still were excited this gene therapy works and this approach could benefit other genetic vision disorders.

By Drs. David Niesel and Norbert Herzog Medical Discovery News The rise of antibioticresistant bacteria is reaching epidemic proportions and if new antibiotics arent created to combat even common bacterial infections we may find ourselves without the ability to combat even the common illnesses. Can you imagine going back to the dark ages before penicillin
While firstworld countries use the most antibiotics a new report reveals that antibiotic use in second and thirdworld countries is steadily increasing. While this may be good in terms of treating and preventing diseases it has some serious consequences for the global threat of antibiotic resistance. As researchers wrote in a recent report When it comes to antibiotic resistance the rich pay with their wallets and the poor pay with their lives.
The use of antibiotics grew by an astounding percent from and according to the report Antibiotic use drives antibiotic resistance. The countries with the biggest increases in antibiotic use were India and South Africa. You can track antibiotic use and resistance worldwide on the Center for Disease Dynamics Economics and Policys website. Three dangerous antibioticresistant bacteria commonly called superbugs to public health are E. coli Klebsiella pneumoniae and Staphylococcus aureus. Between and the incidence of multiple drug resistance in Klebsiella doubled. Doctors in India are using an antibiotic of last resort to fight Klebsiella infections.
There are multiple ways bacteria can become resistant to antibiotics. Bacteria can create new ways to function subverting antibiotics completely. They can change sites within themselves where drugs act rendering the antibiotics ineffective. They can actively pump antibiotics out to remove them. They can produce enzymes that alter or destroy drugs. Bacteria can even work together forming a dense barrier called a biofilm that prevents antibiotics from reaching them. Bacteria are always reinventing themselves and they can do so quickly.
The new report also promotes six strategies that belong in every countrys plan to control the growth of antibiotic resistance. The first is to prevent bacterial infections by improving sanitation water quality and immunization rates. The second strategy is to lower hospital infections and therefore the overuse of antibiotics by improving hygiene and surveillance and creating an antibiotic use protocol. The third is to change the incentives that lead to antibiotic overuse. There are powerful incentives for hospitals doctors communities and agriculture industries that lead to antibiotic overuse. The fourth step is to phase out the practice of using antibiotics to promote livestock growth. China the U.S. and Brazil are the biggest offenders when it comes to agricultural misuse of antibiotics totaling almost tons in . The final two recommendations are efforts to educate medical providers policy makers and citizens about responsible use of antibiotics. Public awareness campaigns political commitment and sensible guidelines can change expectations for antibiotic use.
The only way we are going to solve the spread of antibiotic resistance is with a global focus. With thousands of travelers crisscrossing the world daily the quick spread of infections is a real threat. This is problem that we all face and one we must solve together.

Behind every sip of beer you drink there are millions of years of evolution at work. Research into million years of primate evolution indicates that our ancestors evolved a markedly enhanced ability to metabolize or break down ethanol million years ago. Who knew they had happy hours back then
That doesnt mean that humans have been drinking wine and beer that long. After the first civilizations formed in the Middle East about years ago people discovered that the fermentation process preserves food. That is probably when people began experimenting with alcoholic beverages. Previously historians believed this was the first time alcohol that is specifically ethanol entered the human diet. It has been argued that alcoholism is due to the relatively short amount of time humans have been consuming ethanol which has not allowed us evolve an effective way of metabolizing and digesting it.
However the new theory suggests that early primates began eating low amounts of ethanol around million years ago when flowering plants began producing fruit. These fruits became infected with yeast that was capable of fermenting the sugars stored within. Then as primates began living on the ground below instead of in the trees they would have eaten the fruit that fell to the ground which would have been at various stages of fermentation with even higher levels of ethanol. This would have given them an evolutionary advantage over other species that could not break down ethanol.
When we digest ethanol it is absorbed in the small intestine enters the blood stream moves to the liver and is metabolized there by enzymes called alcohol dehydrogenase or ADH and aldehyde dehydrogenase. These enzymes work together to break down ethanol molecules to carbon dioxide and water. In this process ethanol is first converted to acetaldehyde a very toxic and highly reactive molecule. Some acetaldehyde enters your blood causing tissue damage. We can thank acetaldehyde for our hangovers and their symptoms.
A small amount of alcohol is also excreted through sweat saliva urine and your breath which is how it can be detected by a breathalyzer test. Since alcohol is metabolized more slowly than it is absorbed drinking too much too quickly causes alcohol to accumulate in the body resulting in intoxication.
To determine when our ancestors developed the ability to metabolize ethanol scientists looked for a version of ADH in primates along our evolutionary tree. They looked for when there was a molecular change in the gene encoding the enzyme that made it more active against ethanol. Of the primates that evolved in the past million years only hominids and four other primates have the enzyme. This group split off million years ago which corresponds to our enhanced ability to enjoy ethanol. Even today primates with this enzyme can eat lower quality partially fermented foods unlike other primates.
We have our ancestors to blame for our attraction to alcohol. It turns out our kind has been partying for much longer than previously thought.

Het calls for government to remain resolute now that it has developed sound recommendations
In experimental research repeated exposure of an unfamiliar rejected vegetable during eight sessions over a period of weeks has been shown to increase the consumption and liking of a previously rejected food. Therefore encourage children to sample a wide variety of foods persevere repeated exposure will eventually result in consumption.
Market research data has suggested that children today eat far fewer meals with the family than a generation ago of todays parents consumed meals on a regular basis with their parents compared to just over of todays children. This reduction of family meals consumptions is suggested as a further contributory factor effecting childhood obesity levels.
The increase in numbers of children eating separately from parents is a consequence of our busy lifestyles specifically the large number of hours parents work a week and the increase in the proportion of women who work. This reduces the amount of time available to prepare balanced meals which has helped to drive the increase in consumption of convenience foods that have a relatively low nutrient value. This has also led to an increase in the number of children eating alone where they are more likely to consume high fat low fibre convenience foods.
Therefore the importance of eating regularly in a social setting is important both for nutrient intake and social skills. Perhaps switching the TV off during mealtimes may help to bring the conversation around to the food on the plate and hence improve interest and awareness in food.
Good guidance on what to feed children from an early age is essential so good eating patterns can be established early to foster a lifelong healthy approach to food. Its never too late to change eating habits for the better even if children in a household have already adopted unhealthy eating patterns. If parents focus on changing their own diet and family eating is adopted as the norm even if only on certain days of the week eventually at least some healthy habits will be reflected in their childrens eating patterns

It Is Unintentional Chronic Dehydration That Causes Pain and Disease Including Cancer In The Body
My groundbreaking medical discovery reveals the missing natural element that prevents even cures the bodys painful degenerative diseases naturally and at no cost
I am honored and proud to inform you that my research over years in addition to my medical training and subsequent years as a doctor has exposed the simplest natural cure to a vast number of health problems.
What you are going to find out may at first sound too good to be true This newly uncovered ultimate cure is so simple you will wonder why it has not been discovered until now But I will prove every word you are about to read. I will also tell you why I think the drug industry has concealed this information when asking trusting physicians to prescribe its medications.
What you will discover in this letter is that we in medicine are trained to use chemicals to treat pain and disease when all the body needs is water a simple and abundantly available natural element.
This is the reason why we in medicine have made so many deadly mistakes We are routinely treating symptoms signs and complications of drought in the body with toxic chemicals that kill more rapidly than the dehydration itself
Who in hisher right mind would want to take toxic chemicals when all that their body needs is water free water natural water the ultimate medication of choice to cure pain and prevent disease
The commercial sickcare system and the drug industry do not want you to know that in most health problems you are only thirsty and not sick
They survive and thrive if we remain ignorant of the knowledge of the different ways our bodies show we are thirsty that we are suffering from local or regional drought. When there is shortage of water some parts of the body are forced to go without water. In this report you will get to know how the droughtstricken parts reflect dehydration and how you can recognize that you are truly thirsty. You will recognize why dry mouth is not a sign of thirst but why different pains are
The fundamentals of the information you have in your hands have been scientifically peerreviewed and presented at different national and international medical conferences and published in scientific journals. You are receiving this information directly because the AMA and The National Institutes of Health that you fund with your tax dollars and believe they are working for you have so far refused to tell the American people they were wrong in their past assumptions about the cause of pain and disease in the human body.
Now that I am at it and before we get into the meat of this report let me first give you some background information and then tell you a true story that will dispel any illusions you may have had about the drug companies being on your side
As you will learn I have the scientific distinction of having successfully treated with only water over people suffering from peptic ulcer disease. My report of this event was published as the main editorial of the Journal of Clinical Gastroenterology in June and also reported in the SCIENCE WATCH Science Times of the New York Times Tuesday June .
To me as a clinician it became obvious that these people were suffering from a thirst problem and the label of disease is something we have concocted because we have not understood that pain and local damage can be one of the ways that persistent drought in the body shows itself.
One day at a meeting held in the office of Professor Howard Spiro of Yale University I made this view known. Professor Gregory Eastwood who was then head of the department of gastroenterology at the University of Massachusetts and who is now dean of a prestigious medical school asked me if I could prove this view scientifically. I said I could.

FitTV was an American digital cable and satellite channel owned by Discovery Communications. The channel focused on fitness and exerciserelated programming. FitTV offered programming with such fitness celebrities as Cathe Friedrich Sharon Mann Gilad Janklowicz Marilu Henner Tamilee Webb and others. On February it merged with Discovery Health Channel to become Discovery Fit Health now known as Discovery Life.
International Family Entertainment debuted a continuous preview of the Cable Health Club on August . Beginning Aug. the channel would be available in a halfhour continuous programming format to cable system operators for free. In October the channel moved to hour programming. Jake Steinfeld who had starred on the networks Big Brother Jake hosted its first program and was a constant presence on the channel in its early years.
The original formatting of an hour on Cable Health Club included a minute aerobic conditioning workout at the top of the hour featuring Tamilee Webb a segment on healthy living a Body by Jake workout starting at the bottom of the hour and Fitness Plus a home shopping segment for fitness items and equipment.
In Cable Health Club received new sponsors and minority partners Reebok International its first charter advertiser and Liberty Media. By this time the channel was received in one million homes and carried for two hours a day on the Family Channel. By November the Club was sharing a channel with Prime Sports Northwest on Seattle cable.
By April the Cable Health Club was renamed Fit TV. On June Fox Kids Worldwide Inc. purchased International Family Entertainment.
Americas Health Network was in separate operation from FitTV from March until . The channel was based in Orlando Florida and had an million production center with squarefoot m soundstage built at Universal Studios in late . The executives at the channel were Joe Maddox a former Discovery Channel executive and Webster Web Golinkin who had spent two and a half years planning raising million in capital and building the channel. The majority owner was the Providence Journal Company. The channel also had a fiveyear agreement with Mayo Clinic and IVI Publishing its electronic publisher to provide medical information and illustrative graphics. Mayo and IVI were also minority owners of the channel and other investors included venture capital firm Medical Innovation Partners Inc.
minutes an hour on AHN was devoted to shopping. The Health Mall carried upscale hardertofind items for healthy living. AHN had a deal with Clearwater Floridabased Home Shopping Network to provide orders and shipping infrastructure. For cable operators carriage deals included a small percentage of advertising and shopping revenue.citation needed
With an initial cable audience of subscribers Americas Health Network had reached subscribers by May and million by the time of the sale of its first majority owners. However cable carriage was a long struggle for AHN and other cable outlets that launched in this time frame Electronic Media now TV Week magazine described the environment many cable networks launched in faced as a jungle. Time Warner Cable the primary cable provider in Orlando did not carry AHN and so many people in the channels own hometown were unable to see its programs.
In Providence Journal was bought by the A.H. Belo Corporation. It was Belos first venture into cable television according to Golinkin Belo did not desire to gain any market share in cable. of the channels employees were laid off and they ceased producing live programs. The employees that remained including the entire management team were a skeleton crew to keep the channel running. A sale of most of the Belo stake to ColumbiaHCA Health Care Corp. for million was soon proposed. Columbia wanted to put AHN in its nearly hospitals and surgery centers plus many more outpatient clinics. However during this time period federal investigations over its billing practices government raids charges of Columbia officials with conspiracy and fraud and changes in management at ColumbiaHCA turned the company upside down according to a senior official. This turmoil spurred reviews of company strategies and the cancellation of some transactions including the sale of the AHN stake. New York real estate tycoon Howard Milstein offered a bridge loan which was accepted. Belos stake eventually was bought back by AHN. An investment group of former ColumbiaHCA officials including Richard Scott and David Vandewater took control of the network in late and live series resumed.
During this time another minority investor in the channel was Access Health a referral service.
On June AHN presented the first human birth carried live over the Internet from Orlandos Arnold Palmer Hospital for Children. The birth brought AHN major national and worldwide media attention and was even the focus of an editorial cartoon two days later in USA Today. By this time it reached million cable homes comparable to the CNNSI cable network which would fold in and the Game Show Network.
By June Scott and Vandewater had reduced their stake in Americas Health.
On September News Corp.s Fox Cable Networks Group bought FitTV and merged it with Americas Health Network which Fox Cable already owned in a joint venture with Scott and Vandewater. The resulting network was named The Health Network. In December Fox Cable sold of the channel to WebMD.
By the start of The Health Network reached . million homes. At the start of the station began new headquarters in Los Angeles and about half of its Orlando workforce was laid off leaving people out of work. The station also ran supplementary offices in New York and Nashville. At the time The Health Network said it was moving more of its production to New York and Los Angeles so it could feature more celebrities on its lineup. In the fall of it very nearly relaunched as WebMD Television with new programs and the removal of the AHN studio program library from its schedule that plan was put on hold and Fox received the of the channel it had sold back from WebMD which had lost billion in the year .
On September Discovery Communications bought The Health Network for million in cash and equity. On January Discovery reinstated the FitTV name as Discovery already owned its own health channel Discovery Health.
In March New Yorks Cablevision dropped the channel from its systems resulting in the loss of some three million subscribers down to million. In January the channels carriage remained significantly lower than most cable networks only holding a reach of million homes.
On January Discovery Communications announced that FitTV would be rebranded as Discovery Fit Health on February reflecting the changes to the networks schedule incorporating Discovery Healths programming.

As part of a new personalized medicine initiative the Medical Center offers genetic testing to help doctors determine which medication a patient should take after a stenting procedure in order to prevent blood clots that could lead to serious and potentially fatal heart attacks and strokes.
Fighting infectious disease is a key area for basic science research. Stefanie Vogel PhD professor in the departments of Microbiology and Immunology Medicine is part of a team that found an experimental drug can treat influenza and prevent virusinduced lung injury and death even when administered days after initial infection.
The University of Maryland Lung Transplant Team is the first in the country to use ex vivo lung perfusion to repair donor lungs prior to transplantation. This outofthebody technique in which donor lungs are evaluated and repaired increases the donor lung pool significantly and provides more transplantable lungs to more than on the waiting list. Click here for more information on the Lung Perfusion Program.
Cardiac surgeons at the University of Maryland Heart Center have implanted a ventricular assist device using a minimally invasive technique that employs small openings in the chest a patientfriendly approach that provides the same results as traditional chestsplitting openheart surgery for heart pump implantation. For the patient the new technique means quicker recovery reduced chance of infection and minimal blood loss. Click here for more information about this procedure.
There are many factors that determine a patients wait time for an organ transplant including severity of organ failure blood type and overall health status. Studies have shown that patients who join wait lists at more than one transplant center have an increased chance of getting transplanted sooner. Double listing means that a patient has been evaluated and approved for the transplant wait list at two or more centers. As one of the busiest transplant program in the country with wait times shorter than the national average for kidney and liver transplants the University of Maryland Medical Center encourages patients to list with us as well as list with a transplant center close to home.Click hereto learn more about double listing.
If you were diagnosed with heart failure years ago your chances of recovery were very low. Now advances in medical and surgical treatments make it possible to slow stop or reverse heart failure. And for patients in the advanced stages of heart failure and are not eligible for a heart transplant there are new ways to use ventricular assist devices also called VADs as a proven treatment option.

Medical XpressIt was an exciting year in the medical research field as teams across the world continued to strive for a deeper understanding of the human body and for ways to prevent or treat ailments. Some focused on aging or ways to prevent it while others looked for ways to enhance what Mother Nature gave us naturally.
The geographic origin of AIDS is now knownA widely diverse team of researchers with members from the U.S. and several countries in Europe was able to piece together where when and how the first instance of AIDS in humans occurred. Using statistical analysis the team was able to pinpoint the original infection site as Kinshasa the capital of what is now the Democratic Republic of Congosometime during the s. The team has published their findings in the journal Science. The first human infection came courtesy of a chimpanzee as has been suspected. The teams work illustrates how social change and transport methods contributed to the pandemic that began in the s.
Cesarean section may cause epigenetic changesA study conducted by a team of researchers at the Karolinska Institutet in Sweden revealed evidence that suggests delivering babies via cesarean section can result in changes made to the babys stem cells. Such changes the team found can be blamed for an increased risk of immunological diseases such as asthma diabetes type celiac disease etc. The team has published its findings in the American Journal of Obstetrics and Gynecologyit also reports that it remains unclear whether such epigenetic changes are lifelong or shortlived.
Trigger for stress processes discovered in the brainA team of researchers working at the Center for Brain Research at MedUni in Vienna along with colleagues from the Karolinska Institutet in Sweden discovered an important factor related to stressthe protein secretagogin was found to work as a trigger in the brain by releasing the stress hormone CRH. The team has published its findings in the EMBO Journal. Prior research had shown that CRH is part of the process that leads to signaling in the pituitary gland and to other organs.
Researchers identify first steps in formation of pancreatic cancerA team of bioresearchers working at the Mayo Clinic were able to identify the initial processes that lead to pancreatic cancera finding that could lead to therapies for preventing the cancer from getting started. The team has published its findings in the journal Cancer Discovery. The team discovered that the initial processes which occur at the molecular level came about due to the development of lesions some of which morphed into cancerous growths.
Scientists locate homing signal in brain explaining why some people are better navigatorsResearchers working at University College London identified the part of the brain that is responsible for allowing people to know which direction to travel given their current location and orientation. In a paper published in Current Biology the team explains that the study found that the entorhinal region in the brain which was already known to be responsible for orientation is also responsible for our ability to navigate. Researchers found they were actually able to measure a persons sense of direction using fMRI scans.
Research shows sevenyearolds can think strategicallyA trio of researchers working at the University of Minnesota conducted a study that involved testing children on thinking strategies and found evidence that suggests that kids as young as just six and a half years old are able to use strategies comparable to those of adults when playing games. The team published its results in Proceedings of the National Academy of Sciences finding that the children were able to use recursive thinking and had an ability to infer what others were thinking based on incentives presented to them.
Scientists discover how to switch off autoimmune diseasesA team of researchers working at the University of Bristol reported on a major breakthrough in finding a cure for autoimmune diseases such as multiple sclerosis. In a paper published in Nature Communications the team describes finding a way to stop the immune system from attacking healthy tissueby learning how the process of conversion from attacker to protector works. The process is currently going through clinical development by a biotechnology company affiliated with the university.
Researchers discover genetic marker behind stroke and cardiovascular diseasea team of researchers working at the University of Virginia announced that it had found a genetic variant tied to an increased risk of stroke and certain types of cardiovascular disease. In a paper published in the journal PLOS Genetics the team described the study which included analyzing the genomes of over people and how it also led to findings related to metabolic pathways that play a role in many types of diseases.
Memory loss associated with Alzheimers reversed for first timeA combined team of researchers with UCLA and the Buck Institute for Research on Aging reported that a point therapeutic program they had developed had reduced signs of dementia in nine out of ten volunteer patients involved in the study. In a paper published in the journal Aging the team describes the program and details the results they observed with patients that adhered to it over a three to sixmonth trial period.
Human clinical trial of drug shown to completely reverse diabetes in human islets miceA team of researchers working at the University of Alabama announced that studies they had conducted testing the drug blood pressure medicine verapamil showed that it had completely eliminated any signs of diabetes in lab animalsthat success has led to . million grant from Juvenile Diabetes Foundation. The team has not published the results yet but will likely do so after test trials which are scheduled to start sometime early next year.

Australia is headed for a severe flu season with doctors advising people take precautions to protect themselves from getting sick and spreading the virus.
Mental health advocates are warning that vulnerable people could fall through the gaps because reforms to the sector are being rolled out too quickly. All mental health services funded by the Federal Health Department will soon be commissioned through the recently established primary health networks. But Mental Health Australia is worried that existing services will close before new arrangements are in place.
As NSW and Qld face off in the opening match of this years State of Origin series former State of Origin greats Steve Mortimer and Steve Ella have called on rugby league to put an end to alcohol sponsorship of the sport.
One in six Australians have gone hungry in the past year according to Foodbanks annual survey. The nations longest serving food relief organisation says the hunger plight is reaching crisis point with per cent of welfare agencies and community groups not having enough food to meet demand.
The Australian Population Research Institute says there are too many doctors in Australia which is why GP costs to the government are rising. Other researchers say the rise in costs is reasonable given the ageing population and more chronic conditions while GPs say its not that there are too many doctors thats the problem its that some areas of cities are oversupplied while rural and remote areas are not well serviced.
There are calls for greater regulation of the IVF industry following last nights Four Corners story about the dismally low success rates of fertility treatment in women aged over . Medical legal experts and some of the pioneers of the IVF technology last night issued warnings about the proliferation of socalled snakeoil treatments within fertility clinics. Today fertility specialists have hit back saying Australia is an international leader in infertility research and treatment and is governed by a code of practice thats the envy of the world. But observers of health policy and fertility technology say the industry has undergone enormous change and regulation hasnt kept pace.
A spike in the use of the drug ice on Tasmanias North West coast prompted the state government to invest in programs including the funding of a new bed residential drug and alcohol rehabilitation centre.

The latest arthritis research is recommending ways to slash Australias health budget by hundreds of millions of dollars. The cost to the Government is expected to grow significantly unless more is done to prevent and better manage the condition. Australias peak arthritis body says better treatments for people with the condition including diet changes and exercise routines could save the health system as much as million a year.
Health authorities in the Northern Territory have issued an alert for a potentially fatal mosquitoborne virus. Murray Valley Encephalitis has been detected in chickens on the outskirts of Darwin and while it is considered a rare virus there is no vaccine available.
The decadeslong drought in antibiotic discovery could be over after a breakthrough by US scientists.
Their novel method for growing bacteria has yielded new antibiotics with one deemed very promising.
The last new class of antibiotics to make it to clinic was discovered nearly three decades ago.
The study in the journal Nature has been described as a gamechanger and experts believe the antibiotic haul is just the tip of the iceberg.
The heyday of antibiotic discovery was in the s and s but nothing found since has made it into doctors hands.
Since then microbes have become incredibly resistant. Extensively drugresistant tuberculosis ignores nearly everything medicine can throw at it.
The researchers at the Northeastern University in Boston Massachusetts turned to the source of nearly all antibiotics soil.
The team created a subterranean hotel for bacteria. One bacterium was placed in each room and the whole device was buried in soil.
It allowed the unique chemistry of soil to permeate the room but kept the bacteria in place for study.
The scientists involved believe they can grow nearly half of all soil bacteria.
Chemicals produced by the microbes dug up from one researchers back yard were then tested for antimicrobial properties.
The study shows uncultured bacteria do harbour novel chemistry that we have not seen before. That is a promising source of new antimicrobials and will hopefully help revive the field of antibiotic discovery.
Tests on teixobactin showed it was toxic to bacteria but not mammalian tissues and could clear a deadly dose of MRSA in tests on mice.
The researchers also believe that bacteria are unlikely to develop resistance to teixobactin.
It targets fats which are essential for building the bacterial cell wall and the scientists argue it would be difficult to evolve resistance.
Here is an antibiotic that essentially evolved to be free of resistance said Prof Lewis. We havent seen that before.
It has several independent different tricks that minimise resistance development.
There are limits to the discovery of the antibiotic teixobactin which has yet to be tested in people.
It works on only Grampositive bacteria this includes MRSA and mycobacterium tuberculosis.
It cannot penetrate the extra layer of protection in Gramnegative bacteria such as E. coli.
But even if their method does mark a new era of antibiotic discovery there are big questions.
Sir Alexander Fleming who discovered penicillin warned of the dangers of resistance back in his Nobel prize speech in .
Yet even now prescriptions in England are rising with half deemed inappropriate and contributing to the problem.
But can we be trusted with new antibiotics Or will we make the same mistakes again
Prof Laura Piddock from the University of Birmingham said it was an amazing and exciting study and that the tool could be a gamechanger.
The discovery of this new antibiotic from a new class with a novel mode of action is very exciting.
I hope that teixobactin will now enter clinical development as the basis for a new drug to treat infections.
It could leave many common infections untreatable and make many staples of modern medicine including surgery chemotherapy and organ transplants impossible.
He said it was vital the antibiotic pipeline was reopened if we are to avert a publichealth disaster.
Dr James Mason from Kings College London said the antibiotic pipeline had all but dried up.
Its impressive what theyve done. From one soil sample theyve found one new antibiotic and their approach opens up a new route to a huge number of potential products.
They have shown that screening soil microorganisms for antibiotics is unfinished business.
However he cautioned that although the new antibiotic had exciting properties it was too early to conclude it would entirely avoid the development of resistance.
The researchers said their discovery was similar to vancomycin. It was discovered in the s but it took until the late s for resistance to develop.
They argue the delay in resistance is an inherent property but vancomycin was kept back and not used that extensively Dr Mason said.
Tony Blair says he accepts full responsibility as the Iraq Inquiry report concludes the former PM overstated Saddam Husseins threat and sent UK troops to war in with wholly inadequate plans for the aftermath.
The survey showed that only of women consulted a healthcare professional about their symptoms despite the fact that many women said their symptoms were having a significant effect on their work life social life home life and sex life.
The goal of CliniCloud is to bring healthcare home. For us what that means is a patientcentered and patientmodeled healthcare system where we focus on the fact that consumers want access to healthcare and to a doctor.
Delivering drugs to the lungs via inhalation has a number of potential advantages over traditional routes of administration like pills or injections. For treating pulmonary diseases the obvious logic we are applying is topical delivery to the airways via inhalation.
IDPs is now a widely used acronym that stands for intrinsically disordered proteins. It is the term generally used by the scientific community to refer to a wide variety of proteins that do not have a stable D structure
It is extremely common. Indeed I think it is difficult to encounter an individual that did not experience it at one point or another. It occurs primarily during bacterial and viral infections but also in other diseases like cancer.
An increase in the level of the chemical isoprene may be the warning sign some dogs can detect in the breath of patients with type diabetes who are reaching risky low levels of blood sugar according to research by the University of Cambridge.
Although our knowledge and understanding of tinnitus still has a long way to go in the last few years research has improved its grasp on tinnitus and as such we are heading in a more positive direction for sufferers.
Sarcomas are rare tumours of connective tissue and as a result they can affect any part of the body. These are tumours of fat nerves bone tendons muscle and skin.
Idiopathic pulmonary fibrosis IPF is a debilitating and fatal lung disease that affects approximately million people worldwide. Despite the condition killing more people every year than some cancers it remains relatively unheard of frequently misdiagnosed and little understood.
While many are familiar with type diabetes few are aware of prediabetes a serious health condition that affects million Americans more than one in three adults and often leads to type diabetes.
Since in deaths in the UK are related to a heart or circulatory disease addressing heart health is a concern of national importance. Heart disease is the leading cause of death in men over and an estimated million of us are living with an undiagnosed risk factor high blood pressure.
Demodex mites are one of the most challenging problems that ophthalmologists and optometrists face in the routine care of their patients.

The team published its results in Proceedings of the National Academy of Sciences finding that the children were able to use recursive thinking and had an ability to infer what others were thinking based on incentives presented to them.
Scientists discover how to switch off autoimmune diseasesA team of researchers working at the University of Bristol reported on a major breakthrough in finding a cure for autoimmune diseases such as multiple sclerosis. In a paper published in Nature Communications the team describes finding a way to stop the immune system from attacking healthy tissueby learning how the process of conversion from attacker to protector works. The process is currently going through clinical development by a biotechnology company affiliated with the university.

The decadeslong drought in antibiotic discovery could be over after a breakthrough by US scientists.
Their novel method for growing bacteria has yielded new antibiotics with one deemed very promising.
The last new class of antibiotics to make it to clinic was discovered nearly three decades ago.
The study in the journal Nature has been described as a gamechanger and experts believe the antibiotic haul is just the tip of the iceberg.
The heyday of antibiotic discovery was in the s and s but nothing found since has made it into doctors hands.
Since then microbes have become incredibly resistant. Extensively drugresistant tuberculosis ignores nearly everything medicine can throw at it.
The researchers at the Northeastern University in Boston Massachusetts turned to the source of nearly all antibiotics soil.
The team created a subterranean hotel for bacteria. One bacterium was placed in each room and the whole device was buried in soil.
It allowed the unique chemistry of soil to permeate the room but kept the bacteria in place for study.
The scientists involved believe they can grow nearly half of all soil bacteria.
Chemicals produced by the microbes dug up from one researchers back yard were then tested for antimicrobial properties.
The study shows uncultured bacteria do harbour novel chemistry that we have not seen before. That is a promising source of new antimicrobials and will hopefully help revive the field of antibiotic discovery.
Tests on teixobactin showed it was toxic to bacteria but not mammalian tissues and could clear a deadly dose of MRSA in tests on mice.
The researchers also believe that bacteria are unlikely to develop resistance to teixobactin.
It targets fats which are essential for building the bacterial cell wall and the scientists argue it would be difficult to evolve resistance.
Here is an antibiotic that essentially evolved to be free of resistance said Prof Lewis. We havent seen that before.
It has several independent different tricks that minimise resistance development.
There are limits to the discovery of the antibiotic teixobactin which has yet to be tested in people.
It works on only Grampositive bacteria this includes MRSA and mycobacterium tuberculosis.
It cannot penetrate the extra layer of protection in Gramnegative bacteria such as E. coli.
But even if their method does mark a new era of antibiotic discovery there are big questions.
Sir Alexander Fleming who discovered penicillin warned of the dangers of resistance back in his Nobel prize speech in .
Yet even now prescriptions in England are rising with half deemed inappropriate and contributing to the problem.
But can we be trusted with new antibiotics Or will we make the same mistakes again
Prof Laura Piddock from the University of Birmingham said it was an amazing and exciting study and that the tool could be a gamechanger.
The discovery of this new antibiotic from a new class with a novel mode of action is very exciting.
I hope that teixobactin will now enter clinical development as the basis for a new drug to treat infections.
It could leave many common infections untreatable and make many staples of modern medicine including surgery chemotherapy and organ transplants impossible.
He said it was vital the antibiotic pipeline was reopened if we are to avert a publichealth disaster.
Dr James Mason from Kings College London said the antibiotic pipeline had all but dried up.
Its impressive what theyve done. From one soil sample theyve found one new antibiotic and their approach opens up a new route to a huge number of potential products.
They have shown that screening soil microorganisms for antibiotics is unfinished business.
However he cautioned that although the new antibiotic had exciting properties it was too early to conclude it would entirely avoid the development of resistance.
The researchers said their discovery was similar to vancomycin. It was discovered in the s but it took until the late s for resistance to develop.
They argue the delay in resistance is an inherent property but vancomycin was kept back and not used that extensively Dr Mason said.
Tony Blair says he accepts full responsibility as the Iraq Inquiry report concludes the former PM overstated Saddam Husseins threat and sent UK troops to war in with wholly inadequate plans for the aftermath.

The discovery of the first chemical to prevent the death of brain tissue in a neurodegenerative disease has been hailed as the turning point in the fight against Alzheimers disease.
But scientists say a resulting medicine could treat Alzheimers Parkinsons Huntingtons and other diseases.
In tests on mice the Medical Research Council showed all brain cell death from prion disease could be prevented.
The research team at the Medical Research Council Toxicology Unit based at the University of Leicester focused on the natural defence mechanisms built into brain cells.
When a virus hijacks a brain cell it leads to a buildup of viral proteins. Cells respond by shutting down nearly all protein production in order to halt the viruss spread.
However many neurodegenerative diseases involve the production of faulty or misfolded proteins. These activate the same defences but with more severe consequences.
The misfolded proteins linger and the brain cells shut down protein production for so long that they eventually starve themselves to death.
This process repeated in neurons throughout the brain can destroy movement or memory or even kill depending on the disease.
This process is thought to take place in many forms of neurodegeneration so safely disrupting it could treat a wide range of diseases.
The researchers used a compound which prevented those defence mechanisms kicking in and in turn halted neurodegeneration.
It is rare to get cautious scientists keen to describe a study in mice as a turning point in treating Alzheimers.
It is early science a lot can go wrong between a drug for mice and a drug for humans and the only published data is for prion disease not even Alzheimers.
It is the first time that any form of neurodegeneration has been completely halted so it is a significant landmark. It shows that the process being targeted has serious potential.
If this can be successfully developed which is not guaranteed the prize would be huge.
In Parkinsons the alphasynuclein protein goes wrong in Alzheimers its amyloid and tau in Huntingtons its the Huntingtin protein.
But the errant protein is irrelevant here as the researchers are targeting the way a cell deals with any misfolded protein.
It means one drug could cure many diseases and that really would be something to get excited about.
The study published in Science Translational Medicine showed mice with prion disease developed severe memory and movement problems. They died within weeks.
Whats really exciting is a compound has completely prevented neurodegeneration and thats a first.
This isnt the compound you would use in people but it means we can do it and its a start.
She said the compound offered a new pathway that may well give protective drugs and the next step was for drug companies to develop a medicine for use in humans.
Prof Malluccis lab is also testing the compound on other forms of neurodegeneration in mice but the results have not yet been published.
Side effects are an issue. The compound also acted on the pancreas meaning the mice developed a mild form of diabetes and lost weight.
Any human drug would need to act only on the brain. However this gives scientists and drug companies a starting point.
David Allsop professor of neuroscience at Lancaster University described the results as very dramatic and highly encouraging but cautioned that more research was needed to see how the findings would apply to diseases such as Alzheimers and Parkinsons.
It will be important for these findings to be repeated and tested in models of other neurodegenerative diseases including Alzheimers disease.
Tony Blair says he accepts full responsibility as the Iraq Inquiry report concludes the former PM overstated Saddam Husseins threat and sent UK troops to war in with wholly inadequate plans for the aftermath.

With the recent launch of MITsInstitute for Medical Engineering and Science MIT News examines research with the potential to reshape medicine and health care through new scientific knowledge novel treatments and products better management of medical data and improvements in healthcare delivery.
To understand the progression of complex diseases such as cancer scientists have had to tease out the interactions between cells at progressively finer scales from the behavior of a single tumor cell in the body on down to the activity of that cells inner machinery.
To foster such discoveries mechanical engineers at MIT are designing tools to image and analyze cellular dynamics at the micro and nanoscale. Such tools including microfluidics membrane technology and metamaterials may help scientists better characterize and develop therapies for cancer and other complex diseases.
New medical discoveries depend on engineering advances in realtime multifunctional imaging and quantitative analysis says Nicholas Fang an associate professor of mechanical engineering.
Fang is developing new imaging tools from metamaterials materials engineered to exhibit properties not normally found in nature. Such materials may be designed as superlenses that bend and refract light to image extremely small objects. For example Fang says that todays best imaging tools can capture signaling between individual neurons which may appear as a fuzzy plume of neurotransmitters. A superlens in contrast would let scientists see individual neurotransmitter molecules at the scale of a few nanometers. Such acuity he says would allow scientists to identify certain chemical transmitters that are directly related to particular diseases.
Metamaterials may also help scientists manipulate cells at the microscale. Fang is exploring the use of metamaterials as optical antennae to improve a technique known as optogenetics. This technique developed in and pioneered by MITs Ed Boyden the Benesse Career Development Associate Professor of Research in Education involves genetically engineering proteins to respond to light. Using various colors of light scientists may control the activity or expression of such proteins to study the progression of disease. However researchers have found that the technique requires a large amount of light to prompt a response risking overheating or damaging the proteins of interest.
To solve this problem Fang and his colleagues are looking to metamaterials to design tiny optical receivers similar to radio antennae. Such receivers would attach to a given protein boosting its receptivity to light and thereby requiring less light to activate the protein. The project is in its initial stages Fang says his group is now seeking materials that are compatible with proteins and other biological tissues.
MIT researchers are also developing tools to sort individual cells part of an effort to provide simple costeffective diagnostic tools for certain diseases. Rohit Karnik an associate professor of mechanical engineering is approaching cell sorting from a variety of directions. His lab is fabricating microfluidic or labonachip devices chips as small as a dime that efficiently sort cells separating out those of interest from a sample of blood or biological fluid.
Karniks group employs nanofabrication techniques to etch tiny precisely patterned channels into small squares of polymer. The arrangement of the channels directs fluid capturing cells of interest via cell rolling a phenomenon by which cells roll to one side of a channel attracted by a walls surface coating. The device is a relatively simple passive cellsorter that Karnik says may efficiently sort out material such as white blood cells cells that may quickly be counted to identify conditions such as sepsis and inflammation.
Karnik is also developing small membranes punctured with microscopic pores. Each pore is a few nanometers wide small enough to let individual DNA molecules through. By passing an electric current through the nanopore the researchers can measure certain characteristics of a DNA molecule such as its size and the presence of any additional proteins bound to it.
Such membrane technology may drastically simplify the process of sizing DNA molecules and mapping DNA modifications which are critical for understanding gene regulation and the dynamics of cellular machinery now a lengthy process that involves expensive benchtop instruments. Instead Karnik says nanopore membranes may be a faster cheaper alternative that could work with single DNA molecules with no loss of information from DNAamplification steps.
Researchers are investigating microfluidics not only as a means to sort cells but as a way of replicating whole biological environments at the microscale.
We use microfluidics to develop more realistic models of organs and human physiology so that we can look at for example how a tumor cell interacts with other cells in the local environment says Roger Kamm the Cecil and Ida Green Distinguished Professor of Biological and Mechanical Engineering.
Kamm and his colleagues have developed a microfluidic chip that contains tiny channels and reservoirs in which they can seed various cell types. The group is using the device to study how cancer spreads through the body. Cancer becomes metastatic when tumor cells break off from a primary tumor and cross through a blood vessel wall and into the bloodstream. Kamm is using the groups microfluidic designs to mimic the metastatic process and identify agents to prevent it.
To replicate the lining of a blood vessel Kamm seeds one channel in the chip with endothelial cells. In a neighboring channel he injects a gel mimicking the bodys extracellular matrix. The group can introduce tumor cells into the gel along with other chemical agents. In the controlled setup they can monitor the behavior of tumor cells and the conditions in which the cells penetrate the endothelial lining in order to enter a blood vessel.
This allows us to put cells in close proximity so they can signal with each other in a more realistic fashion Kamm says.
Compared with conventional cancerscreening techniques the microfluidic technique more closely resembles natural processes in the body Kamm says. For example pharmaceutical companies tend to test potential drugs in large batches injecting a drug into tiny isolated wells containing tumor cells. That works well to test for drugs that kill the tumor but not so well for identifying drugs that can prevent metastatic disease.
What were finding is that cells behave completely differently when you have a realistic environment with cells communicating with different cell types and when a cell is in a threedimensional matrix as opposed to when you have a single cell type inside a well on a twodimensional rigid surface Kamm says. Highthroughput systems probably miss a lot of potentially good drugs and they also identify drugs that fail at subsequent stages of testing.
Karnik who has collaborated with Kamm on a few labonachip designs sees such devices and other engineering tools as a key connection in pushing medical discoveries and effective therapies forward.
A clinician might say I need to know whether the patient has this disease or that disease and the biologist would say Oh in order to do that you need to measure molecules A B and C and its up to the engineers to figure out how to do it Karnik says. Thats our key role bridging in between.

Medications add a toxic LOAD that eventually catches up with you. So the less you need the better. WhyYou may feel off not because you are sick but because ALL meds
On one ridge stand scientists clutching discoveries rich with possibility along another are physicians reaching for therapies to alleviate their patients suffering. Between them runs an abyss its floor strewn with abandoned drug candidates and failed clinical trials.
Into this chasm ventured two unsuspecting Harvard Medical School neurobiology professors Clifford Woolf and Bruce Bean. After years of collaboration the scientists wanted to use their experience in deciphering the neurophysiology of pain to develop a new generation of analgesics. Joining forces with a group of neurobiologists and clinicians they sought venture capital. In the group launched Solace Pharmaceuticals with a plan to translate several key discoveries into new drugsand to bridge the gaps between bench and bedside basic and applied science academia and the pharmaceutical industry.
Neither Woolf nor Bean had attempted anything like this before and they found that the journey from idea to drug carried a steeper learning curve and more stepsseeking a patent licensing the technology raising money for further testing among many othersthan either had anticipated. Nevertheless their plan seemed to proceed flawlessly and they quickly identified a compound that relieved pain in rats. Then came the giant hurdle of translation to human clinical trials.
The results were beautifully clear says Woolf. The drug didnt work in humans.
And academics are ill equipped to traverse that valley alone. Medical schools arent set up to do smallscale proofofprinciple human clinical trials much less largescale ones and scientists arent used to navigating regulatory issues says Jeffrey Flier dean of HMS. Those capacities lie in industry.
But the road can be treacherous for the pharmaceutical industry as well. Nine of ten potential medicines entering clinical trials fail. Highprofile latestage drug failures have cost Big Pharma billions of dollars and prompted the industry to seek new innovative approaches to drug discovery and development. These approaches include closer collaborations with academic institutions from which says Flier most of the fundamental discoveries come.
Meanwhile many brilliant universitybased discoveries with true drugdevelopment potential just get left on the pages of medical journals says Frances Jensen an HMS professor of neurology and director of epilepsy research at Childrens Hospital Boston. At the basic science level scientists might do great research get their results published in a highprofile journal and then move on to the next fundamental experiment. Their discovery just sits on a shelf. Nobody picks it up and nobody takes the next step of translation.
Even when promising ideas get noticed universities lack the resources and knowhow to develop them. The continued shrinking of research dollars adds more pressure to an already competitive process. And industry is cutting budgets as well.
These forces have created what one HMS official calls a perfect storm. But the School is creating shelters for those willing to brave the tempest.
Around the time that Solace halted clinical trials of the pain medication that Woolf and Bean had developed the National Institutes of Health was unveiling an initiativeeventually expected to surpass million a yearto address the very issues that had caused the researchers grief. Universities and medical centers around the country began to vie for a share of the funds with the hope of using them to create clinical and translational science centers or CTSCs designed to ease the journey from discovery to therapy.
In Flier had barely settled in his new position as dean of HMS when he learned that the NIH would be phasing out the general clinical research center grants historically awarded to Harvards major teaching hospitals. Instead HMS would have to apply for funding to create a CTSC to be shared with its hospital affiliates and the rest of the University. Flier pulled together a team that under the leadership of Lee Nadler crafted a winning proposal for a fiveyear .million award for such a center now known as Harvard Catalyst.
Were still a long way from even a basic grasp of the mechanisms that underlie most human diseases Flier says. Even when we have that understanding as we do with cystic fibrosis for example its not an easy leap to therapies. Turning discoveries into effective treatments is daunting even before you encounter issues in funding conflict of interest regulation or a host of other arenas.
To help bridge that gap in the past few years Flier created two new postsdean for clinical and translational research held by Nadler and executive dean for research held by William Chin both of whom brought significant experience in translational research and human clinical experimentation.
Medical schools have at their heart a desire to help patients says Chin. We focus on basic researchusing such model systems as mice zebrafish and fruit fliesbecause we need this information for enough insight to learn what leads to human disease in the first place. But remember one of our primary goals is to alleviate human suffering caused by disease and stopping at basic research would leave us short of that goal. So while we dont require scientists to take a translational approach we encourage them to think about it. Were also working to make the process easier for those who do.
Sometimes adds Nadler the hardest step is the first one. My colleagues who are basic scientists often tell me Id really like to pursue translational research. But I dont know what the question should be or how to proceed to the answer.
Chin agrees that collaboration is key to the Schools translational research initiatives. We want to foster more productive multidisciplinary interdepartmental and crossinstitutional work and team formation he says. We believe this will lead to more innovation and creativity.
But that goal bumps up against another hurdle to translational researchthe culture of science. When basic scientists have a translatable discovery Jensen says they generally have to hand that discovery over to a translation scientist and then to a clinician. She adds that the incentives in academic medicinejournal publications grants awards promotionsoften reward individuals rather than teams. In contrast translational and clinical work require more collaboration. Its hard she says for translational researchers to show their added value and get credit for their work.
Part of the solution Nadler says is to evolve the culture and incentives. What we need is a precise question a team of investigators with the diverse skills to solve the problem the required tools and technologies and incentives to bring people from disparate disciplines together. If we say we need an answer to a specific problem and then provide pilot funding for that research he says we give collaborations more focus and means.
As part of its incentivebuilding program Harvard Catalyst provides oneyear pilot grants for investigations that carry a high risk of failure yet offer big payoffs if successful. But theres a catch says Nadler. You cant work with anyone youve worked with before and you must reach across the University system to find a collaborative partner. In three funding cycles thus far the program has awarded grants for innovative projects aimed at for example engineering resistance to epileptic seizures identifying biomarkers for Alzheimers disease and pinpointing neural indicators of dyslexia in infants.
Harvard Catalyst has also introduced practical courses in clinical research and translational medicine including a weeklong introduction to clinical investigation offered several times a year and more advanced classes. Several affiliated hospitals offer training as well.
Through such initiatives says Chin were creating a new breed of investigator. Basic scientists are engaged in learning about disease and physicians are gaining backgrounds in basic science.
Another program that provides critical assistance to foster and advance translational research at HMS is the Technology Development Accelerator Fund launched and operated by Harvards Office of Technology Development. Fueled by donations raised from philanthropic sources the Accelerator Fund is a grantbased program that enables investigators to bridge the often insurmountable development gap in order to establish proofofprinciple and to transform promising earlystage inventions into viable candidates for development commercialization and clinical application. The Accelerator Fund has provided seed funding for projects at the level of approximately each.
Our primary motivation is to accelerate the development of promising new inventions that might otherwise languish for lack of support and validation and to ensure that theyre expeditiously translated for the public good says Isaac Kohlberg the Universitys chief technology development officer. We cant predict or pick winners with certainty. Its all about planting the right seeds nurturing the seedlings encouraging them to blossom and weeding when necessary. Every now and then well be rewarded with a prizewinning flower but we need to seed and cultivate constantly.
Jensen had no such assistance when she ventured into the foreign landscape of translational medicine two decades ago on a search for a new drug to control seizures in newborns. She had long been fascinated by synaptic plasticityhow synapses or the connections between neurons grow with experience. Now she wanted to apply her knowledge to heal injuries to the infant brain.
Such an approachtranslating findings on rodent brains into aids for human infantsrequires a delicate pairing of basic researcher and clinician. But in my department as in many departments the clinicians dont know many of the basic scientists all that well Jensen says. The gulf between the laboratory and clinic researcher and physician and animal model and human patient is a major obstacle in the translational journey. Yet increasingly people on both sides of the gap are working to bridge it.
As clinical medicine advances and as diagnostic tools such as biomarkers and genetics continue their rapid evolution well discover new areas of science ones that you have to go to the bench to study Jensen says. In some cases were discovering that some pathways involved in one disease process are surprisingly also important in another seemingly unrelated disease processor as Jensens work on controlling seizures in infants shows that a drug intended for one disease may be effective against a vastly different disease.
Medications that control seizures in adults for example work only half the time in infants. From research in animal models Jensen knew that antiseizure drugs work by targeting inhibitory synapses. But infant brains have fewer inhibitory and more excitatory synapses than adult brains do. If you give babies a drug that targets inhibitory receptors Jensen says youll find they dont have enough receptors for the drug to work.
A number of laboratories had shown that lowering the number of chloride receptors inside infant brain cells causes them to respond to a drug that targets inhibitory synapses. It turned out that bumetanide a longused federally approved diuretic targets chloride receptors in the kidney. These receptors also are found in human brains with the numbers found in infant brains surpassing those in adult brains. To win the U.S. Food and Drug Administrations approval for repurposing this drug for infant epilepsy Jensen and her colleagues had to prove that the drug targeted neural chloride receptors in animal brains and then show that such receptors were also in the human brain.
Jensens team then encountered the first of several regulatory hurdles that precede clinical trialsthe institutional review board or IRB which ensures patient safety. Because Jensens trial would involve three Harvard hospitals Brigham and Womens Childrens and Massachusetts Generalit needed approvals from three separate IRBs. It took about months Jensen recalls. That process has since been streamlined through a combined IRB thanks to Harvard Catalyst.
Jensen hopes to tap this eased process when a new mechanism she is investigating one that blocks the progression to epilepsy moves from animal to human studies. But since this mechanism might be a new rather than repurposed agent yet more stepsinvolving for instance medicinal chemistry toxicology and drug metabolismmay be required. For those steps academic institutions which rarely have the needed expertise or infrastructure often need to contract with industry.
Randall King and Daniel Finley stumbled upon those limitations while shepherding a new molecule one that helps rid human brain cells of the misfolded proteins implicated in Alzheimers and other neurodegenerative diseases through the gauntlet needed to prove its investment value to potential industry collaborators.
King and Finley were exploring why ubiquitin a small regulatory protein that normally helps neurons dispose of misfolded proteins sometimes fails. Wayward proteins accumulate forming the signature plaques of neurodegenerative diseases. Finley an HMS professor of cell biology and King an HMS associate professor of cell biology discovered that in cell cultures the enzyme Usp slows the degradation of an Alzheimers diseaselinked protein. So the researchers began to hunt for a Usp inhibitor.
They worked with ByungHoon Lee an HMS research fellow in cell biology who using the Schools Institute of Chemistry and Cell BiologyLongwood screening facility developed a highthroughputscreening assay to search for molecules that inhibited only Usp. The strongest candidate christened IU easily entered both mouse and human cells in cultures and boosted ubiquitins beneficial activity. Although the results were good they werent attractive enough for investors. Pharmaceutical companies tend to have a weak appetite for risk says King.
To make their invention more viable for development and commercialization the researchers needed to demonstrate that the molecule could penetrate neurons. And they needed to boost the molecules potency. Those steps required more medicinal chemistry than they could provide. It was a perfect project for the Accelerator Fund. Kohlberg who oversees the program says this early stage of technology development is where many promising university technologies run aground. The Accelerator Fund enables early innovations to achieve preliminary validation he says and selects earlystage technologies that manifest significant translational promise.
King and Finley now have a compound that not only can cross the bloodbrain barrier but is also ten times more potent than the previous compound. That work made the innovation more attractive to potential industry partners says King. As a result OTD identified potential partners held discussions with a number of industry groups and recently concluded a major agreement with a biotech company Proteostasis Therapeutics for the development and commercialization of this technology.
This progress would have been impossible without the Accelerator Fund Kohlberg says. The fund not only supported the project enabling the key medicinal chemistry work to be done but also devised an effective intellectual property strategy and undertook a dedicated marketing and licensing program. All of these steps culminated in our now having a strong industry partner thats committed to the commercial development of this technology and that can we hope take it to the clinic in the near future. If all goes well Finley points out it will still be two to three years before the scientists can test their molecule in human studies.
Even after their disappointing first attempt Clifford Woolf and Bruce Bean wanted to see their work result in pain medications. As they pondered new approaches they came up with chili peppers.
The time seemed ripe to pursue an industry partner for development and commercialization. This time OTD identified and held discussions with a number of established companies with relevant expertise. Those led to the negotiation and conclusion of a major licensing and collaboration agreement with Endo Pharmaceuticals which will navigate the regulatory hurdles when it comes time to apply for safety trials in humans possibly next year.
The imperatives of translational medicine and the importance of collaborating with industry are inextricably related Kohlberg says. With rare exception he adds its only through licensing and collaboration with industry partners that earlystage inventions made in academic labs can reach fruition and culminate in a new FDAapproved drug. And such a culmination in therapy represents in many ways the ultimate fulfillment of our core mission to serve the public interest.
Another important feature of agreements with industry relates to intellectual property rights and the right to publish. When industry funds research in our laboratories we expect to be able to publish those findings says Flier. Industry has traditionally sought to sequester results as proprietary as often and as long as possible. More and more though industry realizes its important to publish results and researchers acknowledge the need for patent protection.
The right to disseminate research results is sacrosanct Kohlberg says. In all of our agreements with industry we make certain that the right to publish is inviolableit is absolutely protected and guaranteed.
Previously industry and academia each believed it could do everything alone. In the past partnering with industry was a bit frowned upon Jensen recalls. But actually its a necessary relationship. How else can drugs get to patients Medical schools arent set up to make drugs.
As for Woolf and Beans first failed trek not all was lost. In the reverse of a spinout Woolf brought one of Solaces programs back into his laboratory for further development. The path across the formerly formidable Valley of Death might just turn out to be a twoway street.
It wasnt precisely his bout with mononucleosis that led David Knipe into a career in virology. By the time Knipe now the Higgins Professor of Microbiology and Molecular Genetics at HMS lost a semester of college to the illness he had been primed to become a virologist by a string of inspiring courses and a stint in a leadingedge laboratory. But the combination of illness and inspiration sealed that deal involving Knipe in academiabased innovation and now with the aid of Harvards Office of Technology Development a licensing agreement with a manufacturer that may produce a vaccine for herpes simplex the cause of genital herpes.
In his HMS laboratory Knipe developed a replicationdeficient form of the virus. In mice the mutant virus triggered an immune response without reproducing. Knipes hope is to develop a vaccine for humans based on the mutant. That taskand the clinical trials to test his innovations safety and efficacywill fall to Sanofi Pasteur. This vaccine needs to be tested in people says Knipe. Without this agreement that wouldnt happen.
At HMS such academicindustry partnerships are carefully tended to guard against conflicts of interest whether real or perceived. The Schools policy aims to ensure that academic research remains robust and unfettered and that industry involvement remains collaborative and fruitful. Overall the goal is to translate ideas into powerful new medicines devices and technologies a goal underscored by Jeffrey Flier dean of Harvard Medical School when he announced a revamped conflictsofinterest policy last summer.
Neither academia nor industry alone is equipped to develop the therapies so desperately needed to eradicate diseases worldwide says Flier. For this reason we are committed to encouraging collaborations between our faculty and industry while ensuring the transparency of those relationships through a policy that further codifies and enforces our high standards.
The revised policy upholds the ability of HMS faculty to license technology to pharmaceutical and biotechnology companies hold equity in such companies serve on their scientific boards and establish new ventures. At the same time the policy prohibits academicindustry links that might adversely influence the integrity of such ties. Faculty can no longer accept for example personal gifts or any travel and meals from industry other than those received during allowed activities. As of July faculty members are barred from participating in industry speakers bureaus or accepting any speaking engagement that would dictate the faculty members presentation content.
In the realm of medical education the policy reinforces restrictions barring sales and marketing representatives of medical drug device or supply companies from accessing medical students. Continuing medical education courses may no longer be sponsored by a single company and industry advertising and exhibits at continuing medical education events are restricted.
The conflictsofinterest policy addresses the challenges of academicindustry collaborations says Flier while maintaining the Schools commitment to advancing research in human diseases. To review the policy visit the Integrity in Academic Medicine website.
The decadeslong drought in antibiotic discovery could be over after a breakthrough by US scientists.
Their novel method for growing bacteria has yielded new antibiotics with one deemed very promising.
The last new class of antibiotics to make it to clinic was discovered nearly three decades ago.
The study in the journal Nature has been described as a gamechanger and experts believe the antibiotic haul is just the tip of the iceberg.
The heyday of antibiotic discovery was in the s and s but nothing found since has made it into doctors hands.
Since then microbes have become incredibly resistant. Extensively drugresistant tuberculosis ignores nearly everything medicine can throw at it.
The researchers at the Northeastern University in Boston Massachusetts turned to the source of nearly all antibiotics soil.
The team created a subterranean hotel for bacteria. One bacterium was placed in each room and the whole device was buried in soil.
It allowed the unique chemistry of soil to permeate the room but kept the bacteria in place for study.
The scientists involved believe they can grow nearly half of all soil bacteria.
Chemicals produced by the microbes dug up from one researchers back yard were then tested for antimicrobial properties.
The study shows uncultured bacteria do harbour novel chemistry that we have not seen before. That is a promising source of new antimicrobials and will hopefully help revive the field of antibiotic discovery.
Tests on teixobactin showed it was toxic to bacteria but not mammalian tissues and could clear a deadly dose of MRSA in tests on mice.
The researchers also believe that bacteria are unlikely to develop resistance to teixobactin.
It targets fats which are essential for building the bacterial cell wall and the scientists argue it would be difficult to evolve resistance.
Here is an antibiotic that essentially evolved to be free of resistance said Prof Lewis. We havent seen that before.
It has several independent different tricks that minimise resistance development.
There are limits to the discovery of the antibiotic teixobactin which has yet to be tested in people.
It works on only Grampositive bacteria this includes MRSA and mycobacterium tuberculosis.
It cannot penetrate the extra layer of protection in Gramnegative bacteria such as E. coli.
But even if their method does mark a new era of antibiotic discovery there are big questions.
Sir Alexander Fleming who discovered penicillin warned of the dangers of resistance back in his Nobel prize speech in .
Yet even now prescriptions in England are rising with half deemed inappropriate and contributing to the problem.
But can we be trusted with new antibiotics Or will we make the same mistakes again
Prof Laura Piddock from the University of Birmingham said it was an amazing and exciting study and that the tool could be a gamechanger.
The discovery of this new antibiotic from a new class with a novel mode of action is very exciting.
I hope that teixobactin will now enter clinical development as the basis for a new drug to treat infections.
It could leave many common infections untreatable and make many staples of modern medicine including surgery chemotherapy and organ transplants impossible.
He said it was vital the antibiotic pipeline was reopened if we are to avert a publichealth disaster.
Dr James Mason from Kings College London said the antibiotic pipeline had all but dried up.
Its impressive what theyve done. From one soil sample theyve found one new antibiotic and their approach opens up a new route to a huge number of potential products.
They have shown that screening soil microorganisms for antibiotics is unfinished business.
However he cautioned that although the new antibiotic had exciting properties it was too early to conclude it would entirely avoid the development of resistance.
The researchers said their discovery was similar to vancomycin. It was discovered in the s but it took until the late s for resistance to develop.
They argue the delay in resistance is an inherent property but vancomycin was kept back and not used that extensively Dr Mason said.
Tony Blair says he accepts full responsibility as the Iraq Inquiry report concludes the former PM overstated Saddam Husseins threat and sent UK troops to war in with wholly inadequate plans for the aftermath.

With the recent launch of MITsInstitute for Medical Engineering and Science MIT News examines research with the potential to reshape medicine and health care through new scientific knowledge novel treatments and products better management of medical data and improvements in healthcare delivery.
To understand the progression of complex diseases such as cancer scientists have had to tease out the interactions between cells at progressively finer scales from the behavior of a single tumor cell in the body on down to the activity of that cells inner machinery.
To foster such discoveries mechanical engineers at MIT are designing tools to image and analyze cellular dynamics at the micro and nanoscale. Such tools including microfluidics membrane technology and metamaterials may help scientists better characterize and develop therapies for cancer and other complex diseases.
New medical discoveries depend on engineering advances in realtime multifunctional imaging and quantitative analysis says Nicholas Fang an associate professor of mechanical engineering.
Fang is developing new imaging tools from metamaterials materials engineered to exhibit properties not normally found in nature. Such materials may be designed as superlenses that bend and refract light to image extremely small objects. For example Fang says that todays best imaging tools can capture signaling between individual neurons which may appear as a fuzzy plume of neurotransmitters. A superlens in contrast would let scientists see individual neurotransmitter molecules at the scale of a few nanometers. Such acuity he says would allow scientists to identify certain chemical transmitters that are directly related to particular diseases.
Metamaterials may also help scientists manipulate cells at the microscale. Fang is exploring the use of metamaterials as optical antennae to improve a technique known as optogenetics. This technique developed in and pioneered by MITs Ed Boyden the Benesse Career Development Associate Professor of Research in Education involves genetically engineering proteins to respond to light. Using various colors of light scientists may control the activity or expression of such proteins to study the progression of disease. However researchers have found that the technique requires a large amount of light to prompt a response risking overheating or damaging the proteins of interest.
To solve this problem Fang and his colleagues are looking to metamaterials to design tiny optical receivers similar to radio antennae. Such receivers would attach to a given protein boosting its receptivity to light and thereby requiring less light to activate the protein. The project is in its initial stages Fang says his group is now seeking materials that are compatible with proteins and other biological tissues.
MIT researchers are also developing tools to sort individual cells part of an effort to provide simple costeffective diagnostic tools for certain diseases. Rohit Karnik an associate professor of mechanical engineering is approaching cell sorting from a variety of directions. His lab is fabricating microfluidic or labonachip devices chips as small as a dime that efficiently sort cells separating out those of interest from a sample of blood or biological fluid.
Karniks group employs nanofabrication techniques to etch tiny precisely patterned channels into small squares of polymer. The arrangement of the channels directs fluid capturing cells of interest via cell rolling a phenomenon by which cells roll to one side of a channel attracted by a walls surface coating. The device is a relatively simple passive cellsorter that Karnik says may efficiently sort out material such as white blood cells cells that may quickly be counted to identify conditions such as sepsis and inflammation.
Karnik is also developing small membranes punctured with microscopic pores. Each pore is a few nanometers wide small enough to let individual DNA molecules through. By passing an electric current through the nanopore the researchers can measure certain characteristics of a DNA molecule such as its size and the presence of any additional proteins bound to it.
Such membrane technology may drastically simplify the process of sizing DNA molecules and mapping DNA modifications which are critical for understanding gene regulation and the dynamics of cellular machinery now a lengthy process that involves expensive benchtop instruments. Instead Karnik says nanopore membranes may be a faster cheaper alternative that could work with single DNA molecules with no loss of information from DNAamplification steps.
Researchers are investigating microfluidics not only as a means to sort cells but as a way of replicating whole biological environments at the microscale.
We use microfluidics to develop more realistic models of organs and human physiology so that we can look at for example how a tumor cell interacts with other cells in the local environment says Roger Kamm the Cecil and Ida Green Distinguished Professor of Biological and Mechanical Engineering.
Kamm and his colleagues have developed a microfluidic chip that contains tiny channels and reservoirs in which they can seed various cell types. The group is using the device to study how cancer spreads through the body. Cancer becomes metastatic when tumor cells break off from a primary tumor and cross through a blood vessel wall and into the bloodstream. Kamm is using the groups microfluidic designs to mimic the metastatic process and identify agents to prevent it.
To replicate the lining of a blood vessel Kamm seeds one channel in the chip with endothelial cells. In a neighboring channel he injects a gel mimicking the bodys extracellular matrix. The group can introduce tumor cells into the gel along with other chemical agents. In the controlled setup they can monitor the behavior of tumor cells and the conditions in which the cells penetrate the endothelial lining in order to enter a blood vessel.
This allows us to put cells in close proximity so they can signal with each other in a more realistic fashion Kamm says.
Compared with conventional cancerscreening techniques the microfluidic technique more closely resembles natural processes in the body Kamm says. For example pharmaceutical companies tend to test potential drugs in large batches injecting a drug into tiny isolated wells containing tumor cells. That works well to test for drugs that kill the tumor but not so well for identifying drugs that can prevent metastatic disease.
What were finding is that cells behave completely differently when you have a realistic environment with cells communicating with different cell types and when a cell is in a threedimensional matrix as opposed to when you have a single cell type inside a well on a twodimensional rigid surface Kamm says. Highthroughput systems probably miss a lot of potentially good drugs and they also identify drugs that fail at subsequent stages of testing.
Karnik who has collaborated with Kamm on a few labonachip designs sees such devices and other engineering tools as a key connection in pushing medical discoveries and effective therapies forward.
A clinician might say I need to know whether the patient has this disease or that disease and the biologist would say Oh in order to do that you need to measure molecules A B and C and its up to the engineers to figure out how to do it Karnik says. Thats our key role bridging in between.

Scientists have suggested that levels of the protein called clusterin rise many years before symptoms of Alzheimers disease first appear.
An early test for the condition could allow those patients could have early treatment and make improvements to their lifestyle to minimise the impact of the disease.
The study conducted by the Institute of Psychiatry at Kings College London also found that very high levels of the protein may be linked with more rapid and severe memory loss.
Patient groups said the prospect of a blood test for Alzheimers disease was the holy grail for researchers in this area and the latest findings bring this a step closer.
Alzheimers disease is the most common form of dementia in Britain and affects almost people. This is expected to double by as the population ages.
The ethics of any blood test to identify those in the very early stages of Alzheimers disease would need to be examined carefully as there is no cure for the condition.
The researchers compared blood samples taken from people with either Alzheimers disease mild impairment or normal brain function.
The found that clusterin levels were linked with Alzheimers symptoms and higher levels indicated more rapid and severe memory loss and brain shrinkage as shown on brain scans.
Experiments with mice showed that the protein is produced in increasing amounts with age and is also linked to the development of plaques in the brain which interfere with cell communications systems. The clusterin surrounded the plaques.
It is not known if the plaques are the cause of Alzheimers disease or a sign of it but this research has shown that the body produces greater quantities of clusterin along with the plaques and it may be an attempt to protect the brain from the build up of the plaques.
Therefore high levels of clusterin which can be detected in a blood sample could be used as an early warning sign that the body is already fighting Alzheimers disease.
Using patients in America they also found that clusterin levels can be used to predict Alzheimers onset up to years before symptoms appear. Clusterin levels were measured and compared with brain scans taken from the same patients years later.
This revealed that the patients with high clusterin had high levels of plaques in the brain ten years later and this is an indication of the condition.
The researchers have not yet established what level of clusterin is normal and at what exact level it would indicate Alzheimers was developing and this is the subject of further investigations.
A primary goal in Alzheimers research is to develop an inexpensive easily administered test to accurately detect and track the progression of this devastating disease.
Identifying clusterin as a blood biomarker that may be relevant to both the pathology and symptoms of the disease may bring us closer to this goal.
Other studies have linked the gene involved in the production of clusterin to Alzheimers disease.
Research is the only answer to dementia yet our scientists remain in desperate need of funds. Investing in research now will bring the treatment breakthroughs we so urgently need in a world where million live with this devastating condition.

Using patients in America they also found that clusterin levels can be used to predict Alzheimers onset up to years before symptoms appear. Clusterin levels were measured and compared with brain scans taken from the same patients years later.
This revealed that the patients with high clusterin had high levels of plaques in the brain ten years later and this is an indication of the condition.
The researchers have not yet established what level of clusterin is normal and at what exact level it would indicate Alzheimers was developing and this is the subject of further investigations.
A primary goal in Alzheimers research is to develop an inexpensive easily administered test to accurately detect and track the progression of this devastating disease.
Identifying clusterin as a blood biomarker that may be relevant to both the pathology and symptoms of the disease may bring us closer to this goal.
Other studies have linked the gene involved in the production of clusterin to Alzheimers disease.
Research is the only answer to dementia yet our scientists remain in desperate need of funds. Investing in research now will bring the treatment breakthroughs we so urgently need in a world where million live with this devastating condition.
