The geroscience hypothesis proposes that underlying biological processes, such as the accumulation of senescent cells, have deleterious effects on multiple tissues and increase the risk of many chronic conditions with aging. Senescent cells produce heterogenous biomarkers, also called senescence-associated secretory phenotype (SASP). Circulating concentrations of senescence biomarkers may reflect an underlying burden of senescent cells in various tissues.

Although anelloviruses have been identified in numerous mammalian hosts, their presence in members of the family Delphinidae has yet to be reported. Here, using a metagenomic approach, we characterize complete anellovirus genomes ( = 69) from four Delphinidae host species: short-finned pilot whale (, = 19), killer whale (, = 9), false killer whale (, = 6), and pantropical spotted dolphin (, = 1).

A qualitative study explored perceptions and factors associated with sleep disturbances in cancer survivors between patients with varying levels of psychological distress.
Methods: Thirty-three Cantonese speaking mixed type cancer survivors were recruited from a community cancer care program.
