Three dialysis patients have received the world's first blood vessels grown in a lab from donated skin cells. It's a key step toward creating a supply of ready-to-use arteries and veins that could be used to treat diabetics, soldiers with damaged limbs, people having heart bypass surgery and others. http://phys.org/news228409720.html Medicine & Health - Medical research Mon, 27 Jun 2011 16:08:53 EST news228409720 (AP) -- Scientists say they've found cells in the hearts of mice that can make new muscle after a heart attack, raising hopes that doctors can one day help the human heart repair itself. http://phys.org/news226771459.html Medicine & Health - Medical research Wed, 08 Jun 2011 17:05:41 EST news226771459 Some guy in his pajamas, home sick with bronchitis and complaining online about it, could soon be contributing to a digital collection of medical information designed to help speed diagnoses and treatments. http://phys.org/news225286322.html Medicine & Health - Medical research Sun, 22 May 2011 12:32:36 EST news225286322 Every day the world over, runners hit the streets, pounding the pavement.

Thanks to new research at the University of Pennsylvania, there is new insight into how these processes regulate tissues formation in the heart. http://phys.org/news222693017.html Medicine & Health - Medical research Fri, 22 Apr 2011 12:40:04 EST news222693017 A new study in fruit flies offers a broad view of the potent and sometimes devastating molecular events that occur throughout the body as a result of methamphetamine exposure. http://phys.org/news222539270.html Medicine & Health - Medical research Wed, 20 Apr 2011 17:28:06 EST news222539270 In the future, when you walk into a doctor's surgery or hospital, you could be asked not just about your allergies and blood group, but also about your gut type. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and collaborators in the international MetaHIT consortium, have found that humans have 3 different gut types. The study, published today in Nature, also uncovers microbial genetic markers that are related to traits like age, gender and body-mass index. These bacterial genes could one day be used to help diagnose and predict outcomes for diseases like colo-rectal cancer, while information about a person's gut type could help inform treatment. http://phys.org/news222523896.html Medicine & Health - Medical research Wed, 20 Apr 2011 13:11:53 EST news222523896 Tinnitus, a relentless and often life-changing ringing in the ears known to disable soldiers exposed to blasts, unwary listeners of too-loud music and millions of others, is the result of under-inhibition of key neural pathways in the brain's auditory center, according to scientists at the University of Pittsburgh School of Medicine in this week's early online edition of the Proceedings of the National Academy of Sciences. The discovery, which used a new technique to image auditory circuits using slices of brain tissue in the lab, points the way to drug development and effective treatment for a condition that currently has no cure. http://phys.org/news222361166.html Medicine & Health - Medical research Mon, 18 Apr 2011 15:59:37 EST news222361166 Anti-depressants may help spur the creation and survival of new brain cells after brain injury, according to a study by neurosurgeons at the University of Rochester Medical Center. http://phys.org/news222340603.html Medicine & Health - Medical research Mon, 18 Apr 2011 10:17:11 EST news222340603 Scientists from the Florida campus of The Scripps Research Institute have developed the first of a new class of highly selective compounds that effectively suppresses the severity of multiple sclerosis in animal models. The new compound could provide new and potentially more effective therapeutic approaches to multiple sclerosis and other autoimmune diseases that affect patients worldwide. http://phys.org/news222337751.html Medicine & Health - Medical research Mon, 18 Apr 2011 09:29:31 EST news222337751 Five years ago, patients with Marfan syndrome received new hope when laboratory studies suggested that losartan, an FDA-approved drug used to treat high blood pressure, might prevent the potentially deadly enlargement of the aorta that the syndrome can cause. Now, researchers have a clearer picture of the cellular signals that contribute to progression of aortic aneurysm in Marfan syndrome and how losartan alters those signals. The new information is expected to help guide treatment decisions, as well as efforts to develop therapies that might offer benefits that losartan does not. http://phys.org/news222008770.html Medicine & Health - Medical research Thu, 14 Apr 2011 14:06:28 EST news222008770 (PhysOrg.com) -- Certain cases of major depression are associated with premature aging of immune cells, which may make people more susceptible to other serious illness, according to findings from a new UCSF-led study. http://phys.org/news221236763.html Medicine & Health - Medical research Tue, 05 Apr 2011 16:00:01 EST news221236763 Until now, there have been no witnesses to the death of brain cells in people with Parkinson's disease.

Glitches in the enzymes can trigger diabetes, impair immune function, or drive the spread of cancers, and scientists are finding more and more examples of kinase mutations that drive disease. It’s not surprising that the list of guilty kinases is long, because the family of enzymes is large – in healthy cells, more than 500 different kinases help keep all manner of essential processes running smoothly. http://phys.org/news221140675.html Medicine & Health - Medical research Mon, 04 Apr 2011 14:30:02 EST news221140675 In the future you may hear the doctor say: "Give me your arm and I'll do some heart surgery." http://phys.org/news221138361.html Medicine & Health - Medical research Mon, 04 Apr 2011 13:10:02 EST news221138361 (PhysOrg.com) -- How we perceive the taste of bitter foods -- and whether we like or dislike them, at least initially -- depends on which versions of taste-receptor genes a person has, according to a researcher in Penn State's College of Agricultural Sciences. http://phys.org/news221139373.html Medicine & Health - Medical research Mon, 04 Apr 2011 12:36:30 EST news221139373 Laboratories at the University of New Mexico (UNM), Brown University, and House Ear Institute (HEI) have developed a new technique to observe herpes simplex virus type 1 (HSV1) infections growing inside cells. HSV1, the cause of the common cold sore, persists in a latent form inside nerve cells. Re-activation and growth of HSV1 infections contribute to cognitive decline associated with Alzheimer's disease. Details are published in the March 31 issue of PLoS ONE magazine from the Public Library of Science. http://phys.org/news221138858.html Medicine & Health - Medical research Mon, 04 Apr 2011 12:28:54 EST news221138858 UCSF scientists are reporting several studies showing that psychological stress leads to shorter telomeres – the protective caps on the ends of chromosomes that are a measure of cell age and, thus, health.

In a study appearing in the March 30, online edition of Nature, the dye, also known as Thioflavin T, (ThT) extended lifespan in healthy nematode worms by more than 50 percent and slowed the disease process in worms bred to mimic aspects of Alzheimer's. The research, conducted at the Buck Institute for Research on Aging, could open new ways to intervene in aging and age-related disease. http://phys.org/news220709157.html Medicine & Health - Medical research Wed, 30 Mar 2011 13:06:17 EST news220709157
