Healthy Aging at Moderate Altitudes: Hypoxia and Hormesis
BACKGROUND: Aging is associated with cellular and tissue responses that collectively lead to functional and structural deterioration of tissues. Poor tissue oxygenation, or hypoxia, is involved in such responses and contributes to aging. Consequently, it could be speculated that living at higher altitude, and therefore in hypoxic conditions, accelerates aging. This assumption is indeed supported by evidence from populations residing at very high altitudes (>3,500 m). In contrast, accumulating...
Mild Behavioral Impairment and Quality of Life in Community Dwelling Older Adults
CONCLUSIONS: The study shows that MBI is associated with poorer QoL, independent of sex, on two QoL scales. We addressed depression/anxiety items in the EQ-5D as a potential confounder for the observed MBI-QoL association by conducting a sensitivity analysis that excluded those items from the EQ-5D total score and by employing a novel measure of QoL (QFS-5) that excludes psychiatric symptoms from measurement of QoL. Associations of MBI with the novel QFS-5 were similar to associations between...
Prenatal exposure to undernutrition is associated with a specific lipid profile predicting future brain aging
Prenatal adversity affects cognitive and brain aging. Both lipid and leptin concentrations may be involved. We investigated if prenatal undernutrition is associated with a specific blood lipid profile and/or leptin concentrations, and if these relate to cognitive function and brain aging. 801 plasma samples of members of the Dutch famine birth cohort were assessed for lipidomics and leptin at age 58. Cognitive performance was measured with a Stroop task at 58, and MRI-based BrainAGE was derived...
Utilising an in silico model to predict outcomes in senescence-driven acute liver injury
Currently liver transplantation is the only treatment option for liver disease, but organ availability cannot meet patient demand. Alternative regenerative therapies, including cell transplantation, aim to modulate the injured microenvironment from inflammation and scarring towards regeneration. The complexity of the liver injury response makes it challenging to identify suitable therapeutic targets when relying on experimental approaches alone. Therefore, we adopted a combined in vivo-in silico...

Therapeutic targeting of senescent cells in the CNS
Senescent cells accumulate throughout the body with advanced age, diseases and chronic conditions. They negatively impact health and function of multiple systems, including the central nervous system (CNS). Therapies that target senescent cells, broadly referred to as senotherapeutics, recently emerged as potentially important treatment strategies for the CNS. Promising therapeutic approaches involve clearing senescent cells by disarming their pro-survival pathways with 'senolytics'; or...
