Weight loss—by dietary changes alone or combined with physical exercise—has a positive impact on the production of adipose tissue hormones: Adipose tissue produces less leptin but, instead, more adiponectin, which counteracts diabetes and cancer. This explains, at a molecular level, the health-promoting effect of physical exercise and dietary changes. Heidelberg cancer researchers have published their results in collaboration with colleagues from the US. http://medicalxpress.com/news/2013-03-healthier-hormones-diet.html Health Thu, 07 Mar 2013 11:23:14 EST news281877785 Here's a wake-up call for snorers: Snoring may put you at a greater risk than those who are overweight, smoke or have high cholesterol to have thickening or abnormalities in the carotid artery, according to researchers at Henry Ford Hospital in Detroit. http://medicalxpress.com/news/2013-01-dont-early-future-health.html Sleep apnea Thu, 24 Jan 2013 11:30:47 EST news278249376 New research in Nature concludes the eye – which depends on light to see – also needs light to develop normally during pregnancy. http://medicalxpress.com/news/2013-01-exposure-pregnancy-key-eye.html Ophthalmology Wed, 16 Jan 2013 13:00:05 EST news277561226 Men in their thirties who had inflamed gums caused by severe periodontal disease were three times more likely to suffer from erection problems, according to a study published in the Journal of Sexual Medicine. http://medicalxpress.com/news/2012-12-men-erection-problems-inflamed-gums.html Diseases, Conditions, Syndromes Tue, 04 Dec 2012 00:00:01 EST news273780364 Blood vessels are extremely dynamic: depending on the external conditions, they can adapt their permeability for nutrients, their contractility, and even their shape. Unlike cardiac muscle cells, for example, the smooth muscle cells in blood vessels demonstrate a high degree of plasticity, so they can specialise or multiply as required, even repairing damage to the vessel wall. This vascular remodelling is evidently precisely regulated. Disruptions are extremely significant in conditions such as atherosclerosis or high blood pressure. At the Max Planck Institute for Heart and Lung Research in Bad Nauheim, scientists conducting research on genetically modified mice have discovered how external signals regulate vascular remodelling at cell level. This has created an entirely new understanding of regulation, which could pave the way for new approaches in the prevention and treatment of atherosclerosis and other vascular diseases. http://medicalxpress.com/news/2012-11-proteins-remodelling-blood-vessels.html Medical research Tue, 13 Nov 2012 13:24:58 EST news272035465 Over the last 15 years, researchers have found a significant association between vascular diseases such as hypertension, atherosclerosis, diabetes type 2, hyperlipidemia, and heart disease and an increased risk of Alzheimer's disease. In a special issue of the Journal of Alzheimer's Disease, leading experts provide a comprehensive overview of the pathological, biochemical, and physiological processes that contribute to Alzheimer's disease risk and ways that may delay or reverse these age-related abnormalities. http://medicalxpress.com/news/2012-11-vascular-disease-key-prevalence-alzheimer.html Alzheimer's disease & dementia Mon, 05 Nov 2012 16:45:12 EST news271356276 Recommendations for the practical management of CRT patients have been set out for the first time in an international consensus statement on cardiac resynchronization therapy (CRT) in heart failure. http://medicalxpress.com/news/2012-08-crt-consensus-standardize-patients-worldwide.html Cardiology Tue, 28 Aug 2012 08:10:12 EST news265360204 Tissue implants made of cells grown on a sponge-like scaffold have been shown in clinical trials to help heal arteries scarred by atherosclerosis and other vascular diseases.
