Scientists have found a substance called resveratrol in red wine that slows down the aging process in mice. Will it someday lengthen the lives of humans, too? Morley Safer reports.

IntroductionThe functional unit of the mammary gland has been defined as the epithelial cell plus its microenvironment, a hypothesis that predicts changes in epithelial cell function will be accompanied by concurrent changes in mammary stroma. To test this hypothesis, the question was addressed of whether mammary stroma is functionally altered by the anti-estrogen drug tamoxifen. Methods:Forty female rats at 70 days of age were randomized into 2 groups of 20 and treated with 1.0 mg/kg tamoxifen or vehicle s.c. daily for 30 days, followed by a 3 day wash out period. Mammary tissue was harvested and effects of tamoxifen on mammary epithelium and stroma determined. Results:As expected, tamoxifen suppressed mammary alveolar development and mammary epithelial cell proliferation. Primary mammary fibroblasts isolated from tamoxifen treated rats displayed a 3 fold decrease in motility and incorporated less fibronectin (FN) in their substratum in comparison to control fibroblasts; attribute

In this study, we compared the immunogenicity of the recombinant hepatitis B vaccine, which was intramuscularly injected at 0, 1, and 6 months of age, in 71 infants born to mothers with positive or negative ...

Proponents of calorie restriction tout the practice as a means toward a long life. according to a new study, calorie restriction is not healthy, nor does it increase our lifespan. Much research has been devoted to the notion that calorie restriction decreases our chances of developing heart disease, cancer, Alzheimer's disease, even delaying the effects of aging. Some research articles have referenced calorie restriction as 'the fountain of youth'. Current research shows that calorie restriction does not extend life.read more

Authors: Yeap BB As men age, testosterone levels decline, and decreased testosterone levels are associated with increased risks of osteoporosis, metabolic syndrome, type 2 diabetes mellitus and mortality. Nevertheless, it is still uncertain whether reduced testosterone level is a cause of ill-health or a marker of pre-existing disease, as systemic illness lowers testosterone levels. Most circulating testosterone is bound to sex-hormone-binding globulin (SHBG) and albumin, whereas a small proportion circulates as free testosterone. Decreased SHBG level is associated with increased risks for insulin resistance and metabolic syndrome, although it would also be expected to be associated with increased free testosterone level. During male aging, total and free testosterone levels fall while...

(Agency for Science, Technology and Research (A*STAR), Singapore) New research on genetic basis of psoriasis may prove important for early diagnosis and prediction of an individual's risk for this common chronic skin disease.

A growing body of evidence demonstrates that we can take steps to delay age-related cognitive decline, including in some cases that which accompanies Alzheimer's disease, according to a study published in the January 2009 issue of the Journal of Alzheimer's Disease. Thomas B.
