Biology of aging brain

Molecular biology of brain aging and neurodegenerative disorders.

A significant component of the aging process is genetically determined. Numerous theories of aging exist, many of which postulate the existence of "longevity genes." Recent advances in molecular biological and other techniques have allowed a significantly greater understanding of aging and age-related disease. This will be illustrated by four genetic and sporadic diseases: Alzheimer's disease (...

Biology of Aging

In spite of the substantial success of modern medicine in curing specific diseases and greatly increasing the average life-span, there has been a complete failure to alter the maximum age that human beings can attain. We live no longer than our ancestors. Marion Lamb's excellent book is devoted to the apparently irreversible process of senescence, and represents a considerable achievement in re...

Molecular biology of aging.

Aging seems to reflect a patterned program of decline in functional reserves and a reduced ability to maintain homeostasis. Advances in molecular biology have provided new insights into the process of aging at the cellular level. In this review, a few selected models of aging that illustrate the molecular methods and techniques used in aging research are discussed.
