Metformin and tBHQ Treatment Combined with an Exercise Regime Prevents Osteosarcopenic Obesity in Middle-Aged Wistar Female Rats. [PDF]

open access: yesOxid Med Cell Longev, 2021
Osteosarcopenic obesity (OSO) is characterized by bone density, mass, and muscle strength loss, in conjunction with adipose tissue increase. OSO impairs physical activity and mobility, provoking autonomy loss; also, it is known that augmenting body fat in the elderly decreases life expectancy.

Low-Intensity Exercise Routine for a Long Period of Time Prevents Osteosarcopenic Obesity in Sedentary Old Female Rats, by Decreasing Inflammation and Oxidative Stress and Increasing GDF-11. [PDF]

open access: yesOxid Med Cell Longev, 2021
The loss of skeletal muscle mass and strength is known as sarcopenia; it is characterized as a progressive and generalized muscle disorder associated with aging. This deterioration can seriously compromise the elderly’s health and reduce their quality of life.

Unveiling the Proteomic Landscape of Extracellular Vesicles: Implications for Neurodegeneration and Neuroprotection. [PDF]

open access: yesJ Neurochem
Extracellular vesicles (EVs) are tiny, membrane‐covered packets that cells naturally release to send molecular information to one another. In the brain, they function as couriers that move proteins, lipids, and other signals between neurons, glial cells, and the blood–brain barrier.

Sex Differences in Age-Associated Type 2 Diabetes in Rats-Role of Estrogens and Oxidative Stress. [PDF]

open access: yesOxid Med Cell Longev, 2019
Females live longer than males, and the estrogens are one of the reasons for this difference. We reported some years ago that estrogens are able to protect rats against oxidative stress, by inducing antioxidant genes. Type 2 diabetes is an age‐associated disease in which oxidative stress is involved, and moreover, some studies show that the prevalence ...
