Acupuncture to Boost Muscle Health
Muscle loss can have a significant impact on a person’s quality of life, leading to decreased mobility and strength. A study published in the Journal of Acupuncture and Meridian Studies offers evidence that acupuncture may stimulate muscle regeneration and preserve muscle health, thus serving as a potentially noninvasive solution to muscle atrophy. The study of patients with sarcopenia, a disorder involving accelerated muscle loss, was conducted at Nanjing Hospital of Traditional Chinese Medicine. The control group was given nutritional treatments, and the study group was given the same nutritional treatments plus 24 sessions of electro-acupuncture over the study’s 12-week period. While both groups experienced improvements, the acupuncture group experienced more significant improvements in skeletal muscle mass and grip strength, as well as the ability to complete a 20-foot walk more than one minute quicker.
According to a paper published in Nature, researchers have made significant strides in the development of an artificial kidney. This exciting breakthrough offers hope for patients on waiting lists for transplants. Engineered using human stem cells, the new artificial kidney can filter blood and produce urine just like a natural kidney. The bio-hybrid device combines microchip filters and living kidney cells, leveraging the body’s natural blood pressure for filtration. Its potential to mimic the function of a real kidney without the need for dialysis or immunosuppressive drugs might render it a game-changing alternative to traditional kidney transplants and dialysis treatments. While the artificial kidney has shown promise in initial animal tests, there is still a long journey ahead before it can be safely implanted in humans.
Vitamins May Improve Memory Taking multivitamin supplements may improve memory in older adults, according to a study published in The American Journal of Clinical Nutrition. The randomized, controlled trial involved 3,562 individuals 65 and older that were given either a placebo or a daily multivitamin supplement and evaluated after one year. Those that took multivitamins had better memory performance compared to the placebo group. While further research is needed to understand how and which vitamins affect memory, the study suggests that these supplements are safe, accessible and beneficial for older adults looking to maintain cognitive function.
