Your chronological age and biological age might not be the same. Chronological age is the number of years you've been alive, while biological age refers to how old your cells and tissues are based on physiological evidence. If you're especially healthy and fit for your age, your biological ...
Theory also predicts that behavioural adjustments should respond to remaining longevity (physiological age) rather than chronological age, but very little information relevant to this issue exists. We studied age-related changes in mating behaviour in an acoustic moth species (Achroia grisella; ...
Maybe age really is just a number. Once my grandfather got up into his 80s, it became very hard for anyone outside the family to guess how old he really was. He was never stooped like other octogenarians, he retained a lush head of salt-and-pepper hair that he kept neatly combed, ...
Physiological age is defined as the physiological status of a seed tuber at any time, determined by genotype, chronological age, and environmental conditions... DO Caldiz - 《Potato Research》 被引量: 21发表: 2009年 Chronological vs. Physiological Age as Determinants of Mating Decisions: Studies...
Interestingly, the integration of chronological age did not dramatically improve the model's performance. Limitations include the use of a national registry and a single frailty index. This provides impetus to explore biological age, rather than chronological age, as a potential tool for surgical ...
Some humans age faster than others. Variation in biological aging can be measured in midlife, but the implications of this variation are poorly understood. We tested associations between midlife biological aging and indicators of future frailty risk in the Dunedin cohort of 1,037 infants born the ...
Currently, it remains unclear how cells make the decision to differentiate into one of the two cell types. Davidson and colleagues[11]proposed that the differentiation of Q and NQ cells is determined by an epigenetic change before entering the post-diauxic phase...

A regression model based on Kernel partial least squares algorithm was built to correlate the chronological age of healthy male individuals with their "physiological age" as determined from their urinary EAAS profile. Strong correlation (R2?=?0.75; slope?=?0.747) and good prediction ability of the...
There is much for caregivers and cardiovascular researchers to learn about how the linear passing of time from birth to old age, compared with how the accumulation of molecular and cellular changes result in a decline of cognitive and physiological function (Central Illustration). The series ...
