Siglec receptors impact mammalian lifespan by modulating oxidative stress. [PDF]

, 2015
Aging is a multifactorial process that includes the lifelong accumulation of molecular damage, leading to age-related frailty, disability and disease, and eventually death. In this study, we report evidence of a significant correlation between the number

Obesity accelerates thymic aging

Blood, 2009
Abstract As the expanding obese population grows older, their successful immunologic aging will be critical to enhancing the health span. Obesity increases risk of infections and cancer, suggesting adverse effects on immune surveillance.

Failure of immunosurveillance accelerates aging [PDF]

OncoImmunology, 2019
Immunosurveillance is generally conceived as a mechanism through which the immune system detects and eliminates (pre-)malignant cells, thus reducing the risk of developing cancer. A recent paper by Ovadya et al. demonstrates that knockout of the gene coding for perforin-1 causes accelerated accumulation of senescent cells in multiple mouse organs ...

Obesity and Accelerated Aging

The Journal of nutrition, health and aging, 2023
Abstract Obesity in the older population has increased in prevalence and incidence over the last several decades and has been associated with a decline in physical function, quality of life, and increased risk of complications from cardiometabolic diseases. Several interrelated hallmarks of aging have been proposed.

Subfertility reflects accelerated ovarian ageing [PDF]

Human Reproduction, 2003
The aim of the study was to explore the extent to which accelerated ovarian ageing may lead to subfertility early in reproductive life and eventually cause early menopause.The population studied (n = 2393) never used oral contraceptives, hormone replacement therapy or an intrauterine device.

Rheological aging and rejuvenation in solid friction contacts

, 2002
We study the low-velocity (0.1--100 $\mu$m.s$^{-1}$) frictional properties of interfaces between a rough glassy polymers and smooth silanized glass, a configuration which gives direct access to the rheology of the adhesive joints in which shear localizes.
