Drug prevents Type 2 Diabetes in Majority of High-Risk Individuals

A pill taken once a day in the morning prevented type 2 diabetes in more than 70 percent of individuals whose obesity, ethnicity and other markers put them at highest risk for the disease, U.S. scientists report. The team also noted a 31 percent decrease in the rate of thickening of the carotid artery, the major vessel that supplies blood to the brain. The study, which enrolled 602 participants through The University of Texas Health Science Center San Antonio and seven collaborating centers, is Read more

Eating Apples Extends Lifespan of Test Animals by 10 Percent

Scientists are reporting the first evidence that consumption of a healthful antioxidant substance in apples extends the average lifespan of test animals, and does so by 10 percent. The new results, obtained with fruit flies -- stand-ins for humans in hundreds of research projects each year -- bolster similar findings on apple antioxidants in other animal tests. The study appears in ACS's Journal of Agricultural and Food Chemistry. Zhen-Yu Chen and colleagues note that damaging substances generated Read more

Placebo Effect Works Both Ways

Poor expectations of treatment can override all the effect of a potent pain-relieving drug, a brain imaging study at Oxford University has shown. In contrast, positive expectations of treatment doubled the natural physiological or biochemical effect of the opioid drug among the healthy volunteers in the study. The study of the placebo effect -- and its opposite the nocebo effect -- is published in Science Translational Medicine. The findings suggest that doctors may need to consider dealing with Read more
