Biological mechanisms of ageing [PDF]

open access: yesEye, 1987
In a short review of the theories or proposed biological mechanisms of ageing it is necessary to be very selective in the ideas which are included or rejected. Although many theories of ageing are advanced in the literature a high proportion can be considered to be special cases of a previous hypothesis. No one individual theory satisfactorily explains

Age Prediction in Healthy Subjects Using RR Intervals and Heart Rate Variability: A Pilot Study Based on Deep Learning

open access: yesApplied Sciences, 2023
Autonomic cardiac regulation is affected by advancing age and can be observed by variations in R-peak to R-peak intervals (RRIs). Heart rate variability (HRV) has been investigated as a physiological marker for predicting age using machine learning ...
