Watch nowThis study shows that exercise that promotes muscular strength may be important for longevity. Other studies have shown that muscle mass is positively correlated with a longer lifespan. As with all observational studies, causality cannot be established. However, adjustments were made to reduce the influence of other factors such as age, sex, health status, lifestyle behaviors and education level. ... exercise aging muscle
Read moreRandomized controlled trial finds that high dose vitamin D supplementation (4,000 IU/day) for 18 weeks improves visual memory in healthy adults but low-dose vitamin D (400 IU/day) does not. Serum 25 hydroxy vitamin D levels increased significantly more in the high dose group (from 27 ng/ml to 52 ng/ml) than the low dose group (24 ng/ml to 34 ng/ml). What is interesting is that even though 34 ng/ml is considered sufficient, it still was not enough to improve visual memory. It has been suggested that visual memory tasks place greater demands on cognitive processing, organization, planning, and o... vitamin d brain performance memory vitamin a
Read moreFasting before exercise increased the expression of genes in adipose tissue that signify that stored fat is being used to fuel metabolism in overweight men but eating a meal 2 hours before did not. There was also greater fat oxidation (burning of fat) during exercise in the fasted state. One potential caveat is the meal was composed of refined carbohydrates and sugars (ie. cornflakes, bread with jam). It would be interesting to see if the same results hold true for either a high-fat meal or a meal rich in fiber (ie. vegetables). The question is...is it the food type or just the signaling pathw... exercise obesity fasting fat carbohydrates

Read moreFTA: > One way many cancers grow resistant to treatment is by generating a web of blood vessels that are so jumbled they fail to provide adequate oxygen to the tumor. With oxygen starvation, the tumor gains a sort of cloaking device that protects it from the toxic effects of chemotherapy drugs and radiation, which are designed to seek out well-oxygenated tissue. Researchers have long tested various approaches to improving blood flow to the tumor in the hopes of restoring potency to treatments, however, to date, not much has shown promise. ... exercise cancer
