Epigenetic ageing accelerates before antiretroviral therapy and decelerates after viral suppression in people with HIV in Switzerland: a longitudinal study over 17 years

Epigenetic clock

An epigenetic clock is a biochemical test that can be used to measure age. The test is based on DNA methylation levels, measuring the accumulation of methyl groups to one's DNA molecules. The strong effects of age on DNA methylation levels have been known since the late 1960s. A vast literature describes sets of CpGs whose DNA methylation levels correlate with age. The first robust demonstration that DNA methylation levels in saliva could generate age predictors with an average accuracy of 5.

Zéro

Zéro est un chiffre et un nombre. Son nom a été emprunté en 1485 à l’italien zero, contraction de zefiro, issu du latin médiéval zephirum, qui représente une transcription de l’arabe ṣĭfr (صفر), le vide (qui en français a également donné chiffre). Le zéro est noté sous forme d’une figure fermée simple : 0. En tant que chiffre, il est utilisé pour et marquer une position vide dans l’écriture des nombres en notation positionnelle. En tant que nombre, zéro est un objet mathématique permettant d’exprimer une absence comme une quantité nulle : c'est le nombre d'éléments de l’ensemble vide.

Timeline of aging research

This timeline lists notable events in the history of research into senescence or biological aging, including the research and development of life extension methods, brain aging delay methods and rejuvenation. People have long been interested in making their lives longer and healthier. The most anсient Egyptian, Indian and Chinese books contain reasoning about aging. Ancient Egyptians used garlic in large quantities to extend their lifespan.
