Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by amyloid-β (Aβ) accumulation, tau hyperphosphorylation, neuroinflammation, and synaptic loss. Existing therapies provide only modest symptomatic relief and fail to slow disease progression. Beyond its role in promoting pituitary growth hormone (GH) secretion, growth hormone-releasing hormone (GHRH) has shown neuroprotective effects in experimental ischemic stroke and spinal muscular atrophy. Here, we explored...

With elderly populations increasing in many countries, rates of Alzheimer disease and related dementias (ADRD) are expected to rise worldwide in the coming years. Low-income and middle-income countries, where barriers to health care are most pronounced and research representation is limited, are predicted to experience the greatest increases in ADRD prevalence. Access to advanced diagnostic and research tools, such as neuroimaging, is severely restricted in these regions, but low-field MRI is...

Regular physical activity is fundamental in promoting health and longevity. Numerous studies highlight the beneficial effects of exercise on metabolic parameters, but uncovering the mechanisms underlying the complex cellular responses and adaptations remains challenging in humans. Thus, animal models, in particular rodent models, have been indispensable for unveiling the underlying biological responses to exercise. Studies with precise exercise designs and diverse genetic models are vital for...
