As mice and other organisms age, the pool of neural stem cells in the brain shrinks and produces fewer new neurons cialis-pills.org http://www.cialis-pills.org . These natural changes correlate with the gradual loss of cognitive ability and sensory functions that occur as we approach the end of our lives. However, the lifetime of some experimental animals can be artificially extended by mutating genes involved in metabolism, and some humans outlive their life expectancy by decades. Brunet and her colleagues wanted to know.

Cells associated in mice by genes with longevity AffectedA gene with longevity in roundworms and humans is connected have been shown to of stem cells of stem cells, the new neurons form in the adult brain, according to researchers at Stanford University School of Medicine. Study in mice shows that the gene is to play an important role in the maintenance of cognitive function during aging.

Professor Ross commented: ‘This is a key study demonstrates that low levels of testosterone is in males cancer survivor together and associated with of impaired quality of life, however, is the relationship between testosterone levels and quality of life complexity and appears off. On a threshold no a direct correlation. Now we need interventional trials to identify having of testosterone, which young male cancer survivor substitute therapy replacement therapy. ‘ items: Diana M. Greenfield, Stephen J.
