Dontsov V.I. Methods of aging research (Theoretical and experimental gerontology). ISBN: 978-3-8484-1140-5. Lambert Academic Pulishing GmbH&Co. 2012. 330 c. (Russian)

 

An overview of various methods of aging research is provided, allowing the researcher to assess the severity of aging processes both in the study of populations and individual organisms, and in most cases to use the methods himself, without resorting to searching for the original. The article describes theoretical methods of research and mathematical modeling of aging, statistical methods for estimating life expectancy and aging rate, viability, genetic, physiological, biochemical, immunological and morphological methods.
