Natural Selection and the Evolution of Asynchronous Aging [PDF]

open access: yesThe American Naturalist, 2022
AbstractUnderstanding within-population variation in aging rates across different phenotypic traits is a central focus of biogerontological studies. Early evolutionary models predict that natural selection acts to cause all traits to deteriorate simultaneously.

Skin Ageing: Natural Weapons and Strategies [PDF]

open access: yesEvidence-Based Complementary and Alternative Medicine, 2013
The fact that the skin is the most visible organ makes us aware of the ageing process every minute. The use of plant extracts and herbs has its origins in ancient times. Chronological and photo-ageing can be easily distinguished clinically, but they share important molecular features.

Natural history of the aging spine [PDF]

open access: yesEuropean Spine Journal, 2003
The unrelenting changes associated with aging progressively affects all structures of the spinal units. The degenerative process starts early during the first decade of life at the disc level. Discal degeneration is associated with biochemical changes followed by macroscopic alterations including tears and fissures, which may lead to discal herniation,

Effect of live birth on the age at natural menopause and predicting the age at natural menopause [PDF]

open access: yesClimacteric
This study aimed to determine whether live birth affects the age at menopause (AAM), explore the relationship between different characteristics and AAM, and develop a model to project the AAM in middle-aged women. A cross-sectional study was conducted with 630 postmenopausal women in Cyprus between January 2022 and June 2022.

Aging, Natural Death, and the Compression of Morbidity [PDF]

open access: yesNew England Journal of Medicine, 1980
The average length of life has risen from 47 to 73 years in this century, but the maximum life span has not increased. Therefore, survival curves have assumed an ever more rectangular form. Eighty per cent of the years of life lost to nontraumatic, premature death have been eliminated, and most premature deaths are now due to the chronic diseases of ...
