Thinner and younger

...nflammation seems to mediate aging. Overweight and obese people tend to have higher levels of inflammation than lean people, so it makes sense that losing weight might increase average lifespan by lowering the risks of some age-related diseases, such as diabetes and atherosclerosis. But in animal studies n...

Insects and mammals share common fat-building pathway, study suggests

...e found at lower than normal levels in genetically obese mice than in normal mice. "These data support the notion that Hh signaling plays a conserved role, from invertebrates to vertebrates, in inhibiting fat formation and highlighting the potential of the Hh pathway as a therapeutic target for osteoporos...

Researchers develop portable 'vein finder' for faster, more accurate injections

...rd to locate. It's also difficult to find veins in obese people and young children because their vessels are covered by layers of fat." In addition to speed, the vein finder's accuracy will make treatment easier for hospital patients who need ongoing IVs or blood work. Larsen recalls a hospital stay of ...

An essential regulator of body weight revealed

...High levels of NPY in the brain of both hungry and obese mice provided further evidence that NPY was likely to stimulate feeding. Ten years ago, Palmiter's lab created mice that lacked the NPY protein, expecting that they would eat less than normal mice. "We thought they might chronically eat less than n...

Weight control protein may yield antiobesity drugs

...red following leptin treatment, Rui said. However, obese animals, with high blood concentrations of the hormone, often exhibit resistance to leptin's usual effects. As a result, leptin itself has proven to be insufficient for obesity therapy. The new findings reveal SH2-B as a critical component in mainta...

Insulin pulses keep the liver lean

The findings suggest that periods of fasting between meals play a critical role in maintaining a lean and healthy liver by allowing insulin levels to rise and fall, ...
