An essential regulator of body weight revealed

...t. "So I think it's fair to say the POMC neurons gained in stature during the last 10 years as being really important to feeding; meanwhile, the importance of the NPY pathway diminished. To some extent, the field began to think these cells were supporting players, but not really important," said Palmiter....

Grasshopper love songs give insight into sensory tuning

...nce, instead of maximizing the average information gained about natural stimuli, the receptors appear to maximize the information gained about specific, but less often occurring aspects of the stimuli," concluded the researchers. "This r...

Neurotransmitters signal aggressive cancer, offer potential for early diagnosis

...were actually being made. We then took information gained from the mouse and asked whether the same human genes are expressed in poor prognosis as opposed to good prognosis human tumors. We found that the human genes that give rise to the key enzymes required to produce these metabolites were invariably swi...

Drug resistance testing in treatment-naive HIV patients is cost-effective

...n remained below $50,000 per quality-adjusted year gained unless the resistance rate was 1 percent or less, which is much lower than in most areas. An accompanying editorial commentary by Frederick Hecht, MD, and Robert Grant, MD, of the University of California, San Francisco, agrees that "there is now s...
