http://medicalxpress.com/ en-us Medical Xpress internet news portal provides the latest news on Health and Medicine. Sometimes you just can't resist a tiny piece of chocolate cake. Even the most health-conscious eaters find themselves indulging in junk foods from time to time. New research by scientists at the University of Massachusetts Medical School (UMMS) raises the striking possibility that even small amounts of these occasional indulgences may produce significant changes in gene expression that could negatively impact physiology and health. http://medicalxpress.com/news/2013-03-scientists-dietary-gene-physiology.html Medical research Thu, 28 Mar 2013 12:42:41 EST news283693354 Nitric oxide, the versatile gas that helps increase blood flow, transmit nerve signals, and regulate immune function, appears to perform one more biological feat— prolonging the life of an organism and fortifying it against environmental stress, according to a new study. http://medicalxpress.com/news/2013-02-bacteria-nitric-oxide-life-roundworms.html Medical research Thu, 14 Feb 2013 13:20:01 EST news280070122 (Medical Xpress)—As obesity rates continue to rise, experts are searching for answers in the clinic and at the lab bench to determine the types and amounts of food that people should eat. http://medicalxpress.com/news/2013-02-worm-clues-obesity.html Medical research Fri, 08 Feb 2013 06:35:08 EST news279527698 In a study published today online in Science, researchers at Albert Einstein College of Medicine of Yeshiva University have determined the complete wiring diagram for the part of the nervous system controlling mating in the male roundworm Caenorhabditis elegans, an animal model intensively studied by scientists worldwide. http://medicalxpress.com/news/2012-07-connectomics-neural-network-male-roundworm.html Neuroscience Thu, 26 Jul 2012 14:00:05 EST news262521065 The lowly and simple roundworm may be the ideal laboratory model to learn more about the complex processes involved in repairing wounds and could eventually allow scientists to improve the body's response to healing skin wounds, a serious problem in diabetics and the elderly. http://medicalxpress.com/news/2011-11-worms-reveal-secrets-wound-healing-response.html Medical research Thu, 17 Nov 2011 15:40:01 EST news240763772 (Medical Xpress) -- Mouse sperm propel themselves with a whip-like molecular tail that lashes back and forth. Sperm in the roundworm Caenorhabditis elegans crawl along using a flat, fibrous foot called a pseudopod. They couldn’t be more different, and yet they depend on the same enzymes to help them develop and move about, according to a new study by SF State researchers. http://medicalxpress.com/news/2011-11-live-action-worm-sperm-clues-male.html Genetics Fri, 11 Nov 2011 13:44:21 EST news240241454 (Medical Xpress) -- A University of Michigan biologist and his colleagues have found that the strategies used by the tiny C. elegans roundworm to control its motions are remarkably similar to those used by the human brain to command movement of eyes, arms and legs. http://medicalxpress.com/news/2011-11-tiny-worms-human-like-neural-circuits.html Neuroscience Fri, 11 Nov 2011 13:24:20 EST news240240251 A cheap, common heartworm medication that is already being used to fight other parasites in Africa could also dramatically interrupt transmission of malaria, potentially providing an inexpensive tool to fight a disease that kills almost 800,000 people each year, according to a new study published today in the July edition of the American Journal of Tropical Medicine and Hygiene. http://medicalxpress.com/news/2011-07-cheap-common-drug-malaria-transmission.html Diseases, Conditions, Syndromes Wed, 06 Jul 2011 17:34:58 EST news229192478 (Medical Xpress) -- Scientists at Karolinska Institutet have discovered that a gene linked to dyslexia has a surprising biological function: it controls cilia, the antenna-like projections that cells use to communicate. http://medicalxpress.com/news/2011-06-unexpected-function-dyslexia-gene.html Genetics Mon, 20 Jun 2011 05:09:41 EST news227765318
