Marathon running 'bad for the heart'
Date: Oct-11-2013When we think of cardiovascular health, physical activity - such as running - often comes to mind. But new research shows that running a marathon can prompt heart muscle changes that cause the heart to swell, and this is particularly the case in runners with lower fitness levels. The researchers, who reported their findings in the Canadian Journal of Cardiology, say previous studies have found that many sports competitors show signs of injury to the heart muscle and cardiac abnormalities after they exercise for long periods of time...
Vitamin D supplements do not prevent osteoporosis
Date: Oct-11-2013Taking vitamin D supplements does not improve bone mineral density, a study involving more than 4,000 healthy adults published in The Lancet has found. With almost half of adults aged 50 and older in the US using vitamin D supplements, the authors conclude that continuing widespread use of these supplements to prevent osteoporosis in healthy adults is needless. Professor Ian Reid from the University of Auckland in New Zealand and study leader explains: "Most healthy adults do not need vitamin D supplements...
Peanut butter helps diagnose Alzheimer's disease
Date: Oct-11-2013A dollop of peanut butter and a ruler can be used to confirm a diagnosis of early stage Alzheimer's disease, University of Florida Health researchers have found. Jennifer Stamps, a graduate student in the University of Florida (UF) McKnight Brain Institute Center for Smell and Taste, and her colleagues reported the findings of a small pilot study in the Journal of the Neurological Sciences. Stamps came up with the idea of using peanut butter to test for smell sensitivity while she was working with Dr...
Compugen drug candidate demonstrates high effectiveness in type I diabetes animal model
Date: Oct-11-2013Compugen Ltd. (NASDAQ: CGEN), has announced that CGEN-15001, an Fc fusion protein drug candidate derived from a novel immune checkpoint protein discovered by Compugen, has been shown to be highly efficient in preventing the development of disease in a well-accepted animal model of autoimmune type I diabetes, known also as juvenile diabetes.

Global study highlights physician preference for topical treatments for actinic keratosis with short treatment duration to improve patient outcomes
Date: Oct-11-2013Over 90 per cent of physicians treating actinic keratosis (AK) prefer short duration treatment options with fast resolving local skin responses (LSRs),1 is the finding of a global study ('Physician Perceptions and Experience of Current Treatment in Actinic Keratosis') that is being presented today at the 22nd Congress of the European Academy of Dermatology and Venereology (EADV). This is the first study of its kind to look at physician treatment perceptions in actinic keratosis...
Researchers prevent and reverse fibrosis in a mouse model of stiff skin syndrome; Study shows promise for scleroderma
Date: Oct-11-2013The Scleroderma Research Foundation has said that researchers at The Johns Hopkins University working in a novel mouse model of Stiff Skin Syndrome have made key discoveries that may have broad implications for future scleroderma therapy. In a report to be published online on October 10th in Nature, scientists show that integrin-modulating agents can arrest fibrosis in a model of scleroderma-like skin fibrosis and, more strikingly, that established fibrosis can be resolved with such agents...
Social media gives hope to cancer patients
Date: Oct-11-2013When gathering information on the experiences of cancer patients, future clinicians and researchers may turn to blogs, social media and online forums. The internet offers cancer patients a rich source of news and information, as well as providing a platform for patients to share experiences, offer support and discuss their needs. The resulting patient-led discussions form a resource that may prove useful for healthcare professionals...
Origin of MERS coronavirus identified
Date: Oct-11-2013The newly emerged Middle East respiratory syndrome coronavirus (MERS-CoV) has circulated in bats for a substantial time, before making the species leap to humans, according to research published in BioMed Central's open access publication Virology Journal. By analysing the genome of various bat species, scientists show that bat DPP4 genes have adapted significantly as they evolved, suggesting a long-term arms race between the bat and the virus...
Can social marketing help to moderate teenage binge drinking?
Date: Oct-11-2013Young people and alcohol is a challenging issue - with those aged 14 -19 more likely to drink alcohol at risky levels than any other age group.
