New research reinforces the claim that resveratrol–a compound found in plants and food groups, notably red wine–prolongs lifespan and health-span by boosting the activity of mitochondria, the cell's energy supplier. "The results were surprisingly clear," said David Sinclair, a professor of genetics at Harvard Medical School and the study's senior author. "Without the mitochondria-boosting gene SIRT1, resveratrol does not work." Over the last decade, Sinclair and colleagues...

Light of specific wavelengths can be used to boost an enzyme's function by as much as 30 fold, potentially establishing a path to less expensive biofuels, detergents and a host of other products. In a paper published in The Journal of Physical Chemistry Letters, a team led by Pratul Agarwal of the Department of Energy's Oak Ridge National Laboratory described a process that aims to improve upon nature - and it happens in the blink of an eye. "When light enters the eye and hits the...

A previously unknown serine protease forms part of the antibacterial defense arsenal of neutrophil granulocytes Neutrophil granulocytes comprise important defenses for the immune system. When pathogenic bacteria penetrate the body, they are the first on the scene to mobilize other immune cells via signal molecules, thereby containing the risk. To this end, they release serine proteases — enzymes that cut up other proteins to activate signal molecules. Scientists at the Max Planck...

Researchers at the University of California, San Diego, the Medical University of South Carolina, the University of Cincinnati, and American Life Science Pharmaceuticals of San Diego have validated the protease cathepsin B (CatB) as a target for improving memory deficits and reducing the pathology of Alzheimer's disease (AD) in an animal model representative of most AD patients. The study has been published in the online edition of the Journal of Alzheimer's Disease. According to...

Curcumin, a substance extracted from turmeric, prolongs life and enhances activity of fruit flies with a nervous disorder similar to Alzheimers. The study conducted at Linköping University, indicates that it is the initial stages of fibril formation and fragments of the amyloid fibrils that are most toxic to neurons. Ina Caesar, as the lead author, has published the results of the study in the prestigious journal PLoS One. For several years curcumin has been studied as a...

Findings may settle scientific debate surrounding this chemical found in red wine and other foods National Institutes of Health researchers and their colleagues have identified how resveratrol, a naturally occurring chemical found in red wine and other plant products, may confer its health benefits. The authors present evidence that resveratrol does not directly activate sirtuin 1, a protein associated with aging. Rather, the authors found that resveratrol inhibits certain types of...
