German researchers develop first non-invasive test to measure skin aging

...astin, whose degeneration causes the appearance of wrinkles and the progressive loss of skin smoothness. The technique measures relative amounts of collagen and elastin by a single factor, which can be positive or negative, like temperatures. Higher values of the factor correspond to higher collagen content, ...

Biomarkers may hone anti-aging therapies

Lotions and potions that promise to remove wrinkles and other effects of aging crowd cosmetics aisle shelves, but do these treatments really work? Vanderbilt University Medical Center investigators have identified new molecular indicators -- or "biomarkers" -- of aging in the skin that could be used ...

Researchers learn how blood vessel cells cope with their pressure-packed job

...le materials react to stretching by forming stress wrinkles parallel to the direction in which they are being pulled. However, the healthy bovine aorta endothelial cells did not behave that way in tests performed in the laboratory of Shu Chien, a coauthor of the PNAS paper and a professor of bioengineering an...

Cellular Defects in Premature Aging Disease are Reversible

...estored to normal; visually, the nuclei lost their wrinkles and lobes and returned to a natural ellipsoid shape, and the expression of other nuclear proteins was also restored to normal levels. "It's amazing that we could take a cell that looked about ready to die, and a few days later it was healthy and rea...
