Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.

Unraveling the Role of Gene Length in Aging

Aging may be less about specific "aging genes" and more about how long a gene is. Many of the changes associated with aging could be occurring due to decreased expression of long genes, say researchers in an opinion piece publishing March 21 in the journal Trends in Genetics.
