Hormone helps mice 'hibernate,' survive starvation

...at has been shown to lower blood glucose levels in diabetic and obese mice. FGF21, in turn, stimulates the use of stored fats as energy and causes torpor. In properly fed mice, FGF21 is not normally active; however, when the researchers introduced FGF21 into these mice, the animals’ metabolism changed. ...

Maggots rid patients of MRSA

Fat screen delivers plant-derived chemical with antidiabetic effects

...e active. Further study of harmine's effects in diabetic mice found that the chemical increases insulin sensitivity in a manner similar to, though more roundabout than, the predominant antidiabetes drugs. Rather than triggering PPARã directly, the chemical blocks a pathway that normally inhibits fat cells'...

...en late in life. One drug, normally used to treat diabetic patients, seems to produce many of the beneficial effects of a low calorie diet. However, it is important to be sure that healthy people will benefit from the drug. A very low level of toxicity could interfere with the beneficial effects of such a ...
