Researchers work at the frontiers of islet cell transplantation

Tampa, Fla. (Feb. 17, 2011) -- Two studies published in the current issue of Cell Transplantation (19:12) investigate frontiers of islet cell transplantation for treating diabetes. Researchers in Milan, Italy re-examine the role of bone marrow st...

AUGUSTA, Ga. -- Fat appears to associate with some distinctive chemical changes in the DNA -- a finding that may help explain why obesity can increase the risk for chronic problems such as cardiovascular disease and diabetes, researchers repo...

Less fit teens more likely to have precursor to diabetes

A child who is overweight and unfit may already be on the road to developing insulin resistance, an early sign of diabetes, researchers reported today at the American Heart Association's 43rd Annual Conference on Cardiovascular Disease Epidemiology and Prevention. Insulin sensitivity is a measure of how well the body responds to insulin, a hormone that transports carbohydrates from the blood into cells where they are turned into energy. High insulin sensitivity means the body is responding well to insulin. Low insulin sensitivity ? also called insulin resistance ? is often a precursor to diabetes.

Fat that may benefit diabetics reduces weight, blood sugar

Supplementing the diet with a certain fatty acid may lead to better weight control and disease management in diabetics, a new study suggests. Diabetics who added an essential fatty acid called conjugated linoleic acid (CLA) to their diets had lower body mass as well as lower blood sugar levels by the end of the eight-week study. Hyperglycemia, or high blood sugar, is a hallmark of diabetes. Researchers also found that higher levels of this fatty acid in the bloodstream meant lower levels of leptin, a hormone thought to regulate fat levels. Scientists think that high leptin levels may play a role in obesity, one of the biggest risk factors for adult-onset diabetes.
