Insulin boost restores muscle growth in elderly
When most people think of insulin, they think of diabetes — a disease that arises when, for one reason or another, insulin can't do the critical job of helping the body process sugar. But the hormone has another, less well-known function. It's also necessary for muscle growth, increasing blood flow through muscle tissue, encouraging nutrients to disperse from blood vessels and itself serving as a biochemical signal to boost muscle protein synthesis and cell proliferation.

Component of Probiotics Improve Cellular Signs of Aging, Study Says
Title: Effect of lta isolated from bifidobacteria on d-galactose-induced aging. Experimental gerontology.
Summary: A new study shows that a component of the cell wall of bacteria (LTA) can reduce some signs associated with the aging process. Yi et al demonstrated that the use of probiotics in mice improved general appearance, raised antioxidant levels in the brain, increased Il-2 and decreased Tnf-a. In addition, it inhibited DNA damage in lymphocytes. This study showed that LTA can suppress the aging process through a variety of mechanisms and including improving antioxidant levels and improving immune and alteration of gene expression.
