More Clues About Obesity Revealed by Brain-Imaging Study
The idea that obese people eat too much because they find food more palatable than lean people do has gained support from a new brain-imaging study at the U.S. Department of Energy's Brookhaven National Laboratory. The study reveals that the parts of the brain responsible for sensation in the mouth, lips, and tongue are more active in obese people than in normal-weight control subjects.

Embryonic Mouse Stem Cells Reduce Symptoms in Model for Parkinson's Disease
Embryonic mouse stem cells transformed into neurons in a lab dish and then transplanted into a rat model for Parkinson's disease (PD) form functional connections and reduce disease symptoms, a new study shows. The finding suggests that embryonic stem (ES) cells may ultimately be useful for treating PD and other brain diseases. more

US Health Professionals Learn Spanish the "Soap Opera" Way
The rapid influx of Latinos into the United States has caught health-care providers unprepared, experts say.

Testosterone Gel (AndroGel®) Study Demonstrates Safety and Efficacy Up to 42 Months
Researchers from Israel found that sleep apnea patients have significantly higher overnight plasma vascular endothelial growth factor (VEGF) concentrations than did either age-similar snorers or young healthy control subjects. VEGF is a key mediator of angiogenesis (the formation of new blood vessels). Angiogenesis is a prominent physiologic adaptive response of a tissue to hypoxia (inadequate amounts of oxygen available in the blood). Sleep apnea,involving repeated episodes of breathing cessation for longer than 10 seconds, causes hypoxia. more
