(PhysOrg.com) -- Chronic wounds, including venous leg ulcers which are caused by poor circulation in the veins of the legs, are difficult and expensive to treat. Researchers at the University of Pennsylvania School of Medicine have developed the first targeted, short-term delivery method using gene transfer technology to effectively treat venous leg ulcers. http://www.physorg.com/news179085687.html Medicine & Health Thu, 03 Dec 2009 18:30:01 EST news179085687 (PhysOrg.com) -- While studying how the heart is formed, scientists at the University of Pennsylvania School of Medicine serendipitously found a novel cellular source of atrial fibrillation (AF), the most common type of abnormal heart beat. http://www.physorg.com/news176408803.html Medicine & Health Mon, 02 Nov 2009 18:50:04 EST news176408803 The source and mechanisms underlying the abnormal heart beats that initiate atrial fibrillation (Afib), the most common type of abnormal heart beat, have not been well determined. However, a group of researchers at the University of Pennsylvania, Philadelphia, has now identified a population of cells that are like pigment producing cells in the skin (melanocytes) in the atria of the heart and pulmonary veins of mice and humans and uncovered evidence in mice that these cells contribute to Afib. http://www.physorg.com/news174591496.html Medicine & Health Mon, 12 Oct 2009 19:00:01 EST news174591496 (PhysOrg.com) -- Researchers from Boston University School of Medicine (BUSM) have concluded that the 940nm wavelength laser is superior for treating facial spider veins (telangiectasias) as compared to the 532nm wavelength laser. The findings, which appear in the recent issue of Lasers in Surgery and Medicine, are the first time these lasers were tested against each other for superiority. http://www.physorg.com/news174050078.html Medicine & Health Tue, 06 Oct 2009 12:30:01 EST news174050078 Physicians at The Mount Sinai Medical Center in New York became the first in the U.S. to ablate atrial fibrillation using a visually-guided laser balloon catheter. The procedure was performed September 15 by Vivek Y. Reddy, MD, Professor of Medicine and Director of the Cardiac Arrhythmia Service at Mount Sinai Heart, and his colleague, Srinivas R. Dukkipati, MD, Director of Mount Sinai's Experimental Electrophysiology Laboratory. http://www.physorg.com/news172513773.html Medicine & Health Fri, 18 Sep 2009 21:00:01 EST news172513773 A group of genes whose expression is significantly altered following exposure to drug paraphernalia after an enforced 'cold-turkey' period have been identified. Researchers writing in the open access journal BMC Neuroscience studied gene expression in the brains of heroin-addicted rats, identifying those genes that may be involved in precipitating a relapse. http://www.physorg.com/news168806172.html Medicine & Health Thu, 06 Aug 2009 21:40:01 EST news168806172 (PhysOrg.com) -- Natural leaves constantly lose water through evaporation, as the water in their veins is pumped up to the top of the tree. This process, called transpiration, could also create a mechanical water pump effect in synthetic leaves, and be used to generate power. http://www.physorg.com/news168532880.html Physics Mon, 03 Aug 2009 15:42:13 EST news168532880 (PhysOrg.com) -- A new technology involving the fusion of four different types of images into a 3-D map of a patient's brain has helped University of Cincinnati (UC) specialists successfully remove a fist-sized tumor from the brain of an Indiana woman. http://www.physorg.com/news166797844.html Medicine & Health Tue, 14 Jul 2009 14:00:04 EST news166797844 A rare, deadly developmental disorder of the lungs called alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) that usually kills the infants born with it within the first month of life results from deletions or mutations in the FOXF1 transcription factor gene, said a consortium of researchers led by Baylor College of Medicine in a report that appears in the American Journal of Human Genetics. http://www.physorg.com/news163341976.html Medicine & Health Thu, 04 Jun 2009 13:46:48 EST news163341976 Kidney disease patients who are educated about dialysis are more likely to undergo a standard but under-utilized dialysis-related procedure than less knowledgeable patients, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The findings suggest that patients' knowledge about dialysis affects whether they receive optimal care and that physicians should work to educate their patients. http://www.physorg.com/news159727594.html Medicine & Health Thu, 23 Apr 2009 17:47:17 EST news159727594 Individuals diagnosed with a brain arteriovenous malformation (BAVM) -- an abnormal tangle of arteries and veins -- are at increased risk of vessel rupture and bleeding that can cause permanent brain damage. Traditionally, doctors have prescribed preventive interventions like surgery, but there is suggestive evidence that this invasive approach may actually increase risk of a rupture, at least in some patients. http://www.physorg.com/news157826044.html Medicine & Health Wed, 01 Apr 2009 17:35:35 EST news157826044 (AP) -- Surgeons have transplanted a hand onto a Marine who was hurt in a training accident, and he has some movement in his fingers, according to the hospital where the operation occurred. http://www.physorg.com/news157052378.html Medicine & Health Mon, 23 Mar 2009 18:39:55 EST news157052378 Larval (maggot) therapy has similar health benefits and costs compared with a standard treatment for leg ulcers, find two studies published on bmj.com today. http://www.physorg.com/news156710065.html Medicine & Health Thu, 19 Mar 2009 19:34:38 EST news156710065 A pair of studies, led by Medical College of Wisconsin scientists at Children's Research Institute in Milwaukee, may translate into rapid molecular tests to distinguish between hemangiomas and congenital blood or lymph vessel malformations in infants. Hemangiomas are common birthmarks consisting of benign tumors of blood vessels. The studies appear in the January 29, 2009 issue of the journal Blood. http://www.physorg.com/news152464973.html Medicine & Health Thu, 29 Jan 2009 15:23:19 EST news152464973 If blood doesn't move well through your veins and arteries, your tissues and organs aren't getting enough oxygen and nutrients.
