DNA Damage: Health and Longevity

Mitochondrial DNA Damage and Animal Longevity: Insights from Comparative Studies

Chemical reactions in living cells are under strict enzyme control and conform to a tightly regulated metabolic program. However, uncontrolled and potentially deleterious endogenous reactions occur, even under physiological conditions. Aging, in this chemical context, could be viewed as an entropic process, the result of chemical side reactions that chronically and cumulatively degrade the func...

Loneliness, health, and longevity.

BACKGROUND Objective measures of loneliness and poor social contacts are associated with negative health outcomes. However, the influence of subjective loneliness among elderly persons is poorly documented. We hypothesized that loneliness among persons aged 70-90 years is associated with subsequent decline in health, function, and longevity. METHODS Mortality data for subjects aged 70-90 year...

Food and health longevity.

Japan has the longest life expectancy in the world. It was an average 85.59 years for women and 78.64 years for men and 77.2 years for women and 71.9 years for men in average health expectancy in 2004. As the diet becomes more westernized, the number of patients with diabetic, cardiovascular, and cerebrovascular diseases due to the metabolic syndrome is increasing. In 2002, our university was s...
