Newly discovered gene regulates hyperglycemia-induced beta cell death in type 2 diabetes

http://ift.tt/1O2Cdfl Elevated levels of blood glucose (hyperglycemia) can induce the death of the pancreatic beta cells over time. The death of these cells (responsible for the production of insulin) underlies much of the pathology of diabetes. Exactly how and why they die is not fully understood, but a new research report sheds light on the answer and a new therapeutic target.

Is endurance training bad for you?

http://ift.tt/1Us0dYs In 2012, Belgian scientists published a study that concluded that repeated bouts of intensive endurance exercise at the elite level may result in the pathological enlargement of the right ventricle, which, according to the article, is associated with potential health hazards including sudden cardiac death. The publication was the cause of considerable debate among experts in the medical and sports communities. Sports medicine physicians have now tested the conclusions of the 2012 study by examining the hearts of elite master endurance athletes. Their findings refute the hypothesis proposed by their Belgian colleagues.
