HRT and anti-aging

Aging, anti-aging, and hormesis.

As a result of almost 50 years of efforts in collecting descriptive data, biogerontologists are now able to construct general principles of aging and to explore possibilities of gerontomodulation. Most of the data indicate that aging is characterized by a stochastic accumulation of molecular damage and a progressive failure of maintenance and repair, and the genes involved in homeodynamic pathw...
