Rejuvenating old tissue stem cells could help maintain organ function and potentially reverse aging phenotypes. The study explores biochemical cues and signaling pathways, such as Notch/Delta and Wnt, which regulate tissue stem cell function. Researchers have demonstrated the potential to rejuvenate stem cell function, leading to broader organismal rejuvenation.

A Review of Neuroimaging Findings in Repetitive Brain Trauma, sheds new light on the impacts of repetitive brain trauma, particularly in athletes and military personnel.

Testosterone deficiency can manifest in various ways, including fatigue, poor memory, decreased libido, and erectile dysfunction. The AUA guideline recommends using a total testosterone level below 300 ng/dL as a diagnostic cutoff, confirmed by two separate early morning tests. Many men are prescribed testosterone without proper testing, leading to inappropriate treatment and potential risks.

Zinc can inhibit viral replication, reduce lung injury, and enhance the immune system’s response to infections, making it a promising candidate for supporting existing COVID-19 treatments. However, long-term zinc supplementation can lead to copper deficiency, potentially resulting in anemia and neurological issues; therefore, caution is essential.
