An approach to the effects of longevity, sexual maturity, and reproduction on telomere length and oxidative stress in different Psittacidae species [PDF]

open access: yesFrontiers in Genetics, 2023
Introduction: Aging is a multifactorial process that includes molecular changes such as telomere shortening. Telomeres shorten progressively with age in vertebrates, and their shortening rate has a significant role in determining the lifespan of a ...

DNA damage (8-OHdG) and telomere length in captive Psittacidae birds with different longevity. [PDF]

open access: yesFront Vet Sci
Aging is a complex process influenced by internal and external factors. Oxidative stress damages DNA, leading to 8-hydroxy-2’ deoxyguanosine formation (8-OHdG).
