WebBiological aging is considered to occur mainly during the period of survival beyond the natural or essential lifespan (ELS) in Darwinian terms. Organisms survive to achieve ELS by virtue of genetically determined longevity assuring maintenance and repair systems (MRS). WebSep 18, 2024 · Telomere theory proposes that telomere shortening is the trigger for aging. However, it remains uncertain how telomeres lead to aging in organisms. Telomere attrition is regarded as the primary hallmark of aging or the cause of age-associated damage resulting in cellular senescence (Lopez-Otin et al. 2013 ).
WebJun 1, 2004 · The failure to distinguish between aging research (biogerontology) and research on age-associated diseases (geriatric medicine) has been, and still is, a source of many misunderstandings.
