Researchers at Lund University in Sweden have developed a new mouse model that answers the question of what actually happens in the body when type 2 diabetes develops and how the body responds to drug treatment. Long-term studies of the middle-aged mouse model will be better than previous studies at confirming how drugs for type 2 diabetes function in humans. http://medicalxpress.com/news/2013-05-mouse-diabetes.html Diabetes Fri, 03 May 2013 07:50:01 EST news286784059 Massachusetts General Hospital (MGH) researchers have identified a gene variant that helps predict how much weight an individual will lose after gastric bypass surgery, a finding with the potential both to guide treatment planning and to facilitate the development of new therapeutic approaches to treating obesity and related conditions like diabetes. The report receiving advance online publication in The American Journal of Human Genetics is the first to identify genetic predictors of weight loss after bariatric surgery. http://medicalxpress.com/news/2013-05-gene-variant-weight-loss-gastric.html Genetics Thu, 02 May 2013 12:00:02 EST news286710668 Hydrogen sulfide (H2S) may play a wide-ranging role in staving off aging, according to a paper published online ahead of print in the journal Molecular and Cellular Biology. In this review article, a team from China explores the compound's plethora of potential anti-aging pathways. http://medicalxpress.com/news/2013-01-hydrogen-sulfide-anti-aging-agent.html Medical research Tue, 29 Jan 2013 12:03:46 EST news278683401 Fructose, a sugar much maligned in recent years, recently took another hit when a preliminary study by Yale University found that it might stimulate appetite more than other sugar types. The results came as no surprise to Robert Lustig, MD, a pediatric endocrinologist at the UCSF Benioff Children's Hospital who's made headlines for years with his public health crusade against excess sugar consumption. http://medicalxpress.com/news/2013-01-sugar-simmer-brain-fructose-appetite.html Health Mon, 14 Jan 2013 06:04:23 EST news277365651 (Medical Xpress)—A team of researchers at McGill University have discovered a molecular basis for the potential cancer preventive effects of vitamin D. The team, led by McGill professors John White and David Goltzman, of the Faculty of Medicine's Department of Physiology, discovered that the active form of vitamin D acts by several mechanisms to inhibit both the production and function of the protein cMYC. cMYC drives cell division and is active at elevated levels in more than half of all cancers. Their results are published in the latest edition of Proceedings of the National Academy of Sciences. http://medicalxpress.com/news/2012-11-vitamin-d-cells-premalignant-malignant.html Cancer Fri, 23 Nov 2012 07:19:01 EST news272877506 (Medical Xpress)—Previously existing ideas on how advanced maternal age affects adult health of children have to be reconsidered. It had been thought that mothers delivering later in life have children that are less healthy as adults, because the body of the mother had already degenerated due to physiological effects like decreasing oocyte quality or a weakened placenta. In fact, what affects the health of the grown-up children is not the age of their mother but her education and the number of years she survives after giving birth and thus spends with her offspring. This is the conclusion of a new study by Mikko Myrskylä from the Max Planck Institute for Demographic Research in Rostock, Germany carried out with data from 18,000 US children and their mothers. http://medicalxpress.com/news/2012-09-advanced-maternal-age-children-adulthood.html Health Thu, 06 Sep 2012 10:25:44 EST news266145929 Genetics play an important role in the variation in, and risk of, low testosterone concentrations in men. A study by the CHARGE Sex Hormone Consortium, published in the open-access journal PLoS Genetics on Thursday, 6th October, is the first genome-wide association study to examine the effects of common genetic variants on serum testosterone concentrations in men. http://medicalxpress.com/news/2011-10-testosterone-men-affected-genetic-makeup.html Genetics Thu, 06 Oct 2011 17:00:01 EST news237129242
