Cellular stress response is the wide range of molecular changes that cells undergo in response to environmental stressors, including extremes of temperature, exposure to toxins, and mechanical damage. Cellular stress responses can also be caused by some viral infections. [1]
(The main aim in induced comas is to reduce the intracranial pressure, not brain metabolism). [citation needed] Increased extracellular glutamate levels leads to the activation of Ca 2+ permeable NMDA receptors on myelin sheaths and oligodendrocytes, leaving oligodendrocytes susceptible to Ca 2+ influxes and subsequent excitotoxicity.
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
To reduce heart disease risk, Dr. Chen recommends engaging in regular physical activity, eating a nutritious balanced diet, getting an adequate amount of quality sleep, maintaining a healthy ...
Biopsies were taken both before and after a six-week-long endurance exercise training program. The exercise consisted of riding a stationary bicycle for one hour five days a week for six weeks. Of the 13,108 genes with detected expression in the muscle biopsies, 641 genes were upregulated after endurance training and 176 genes were downregulated.
Just 1.5 to 4 minute small bursts of high intensity exercise throughout the day may lower a person’s risk of major cardiovascular events, such as stroke. 4 or 5-minute bouts of intense exercise ...
This idea has preliminary evidence showing that repetitive mild stress exposure may have anti-aging effects in laboratory models. [ 35 ] [ 36 ] Some mild stresses used for such studies on the application of hormesis in aging research and interventions are heat shock , irradiation, prooxidants , hypergravity , and food restriction.
Morning exposure to the sun’s rays can help promote better quality sleep that night, regardless of how much total sunlight you get throughout the day, according to a 2024 study in Journal of ...
