IntroductionAge-related declines in cognitive and motor functions show highly variable trajectories. To better understand the underlying mechanisms, we investigated multivariate associative effects between modifiable vas...

IntroductionAlzheimer’s disease (AD) is strongly associated with cerebrovascular dysfunction and impaired glymphatic clearance. These dysfunctions may precede, contribute to, and interact bidirectionally with AD pathol...

Background and purposeThe aging brain is particularly sensitive to alterations in selenium status. Selenium deficiency has been associated with impaired neural function, cognitive decline, and increased vulnerability to ...

Abstract Astrocytes play key roles in maintaining brain homeostasis, metabolism, and neurovascular integrity, yet their diversity and age-related modulation remain insufficiently understood, particularly across primate l...

Aging is a complex biological process characterized by progressive functional decline and increased vulnerability to age-related diseases, particularly neurodegenerative disorders. At the biological level, aging is chara...

There is a growing interest in the potential of mesenchymal stem cells (MSCs) for implementing regenerative medicine in the brain as they have shown neurogenic and immunomodulatory activities. We assessed the effect of i...

BackgroundHigh blood pressure (BP) is a known risk factor for dementia, but the relationships between BP and gross brain volumes are mixed and are understudied in groups who are at particularly high risk for dementia, su...

Early adversity programs induce changes that can accelerate biological aging. Using the early stress model of maternal separation (MS), we assessed oxidative, metabolic, and biochemical consequences in serum derived from...

BackgroundFrailty is significantly more prevalent in individuals with Parkinson’s disease (PD) than in general population, yet the underlying neuropathophysiological mechanisms remain poorly understood. This study aime...

During aging, the brain undergoes changes that impair cognitive capacity and circuit plasticity, including a marked decrease in production of adult-born hippocampal neurons. It is unclear whether development and integrat...

Background and objectivesMitochondrial dysfunction and oxidative stress are key contributors to the progression of Alzheimer’s disease (AD). Salidroside, a bioactive glycoside derived from Rhodiola rosea, exhibits neur...

Aging is associated with numerous physiological, musculoskeletal, and neurological impairments including a loss of muscle, strength, function, bone mineral, and cognition. Strength training is an effective intervention ...
