Explaining Link Between Heart Failure And Diabetes

Either heart failure or diabetes alone is bad enough, but oftentimes the two conditions seem to go together. Now, researchers reporting in the January Cell Metabolism appear to have found the culprit that leads from heart failure to diabetes and perhaps a novel way to break that metabolic vicious cycle.

"Our findings clarify the reasons why the incidence of heart failure is high among diabetic patients, why the prevalence of insulin resistance is increased in heart failure patients, and why treatment of insulin resistance improves the prognosis of heart failure patients," says Tohru Minamino of Chiba University Graduate School of Medicine.

How Muscle Growth Is Triggered By Exercise

Muscle GrowthWe take it for granted, but the fact that our muscles grow when we work them makes them rather unique. Now, researchers have identified a key ingredient needed for that bulking up to take place. A factor produced in working muscle fibers apparently tells surrounding muscle stem cell "higher ups" that it's time to multiply and join in, according to a study in the January Cell Metabolism, a Cell Press journal.

The Buried Code To Healthy Ageing

Jena`s Leibniz Institute for Age Research Fritz Lipmann Institute (FLI) and Berlin`s Leibniz Institute for Zoo and Wildlife Research (IZW) from Germany are jointly starting a project for ageing research in 2012. Within the framework of the "Joint Initiative Research and Innovation" (PAKT), researchers want to identify molecular networks responsible for a long life in health. Naked mole-rats (Heterocephalus glaber) act as a model organism, these animals can reach a high age without suffering from age-related diseases. The Federal Ministry of Education and Research (BMBF) and the Federal States invest 1.5 million euro within three years for this innovative research.
