Mitochondrial Dysfunction, Nutrition and Aging

By Ward Dean, MD Every cell in the human body is packed with tiny organelles called mitochondria (Fig. 1). Mitochondria are often referred to as...

Fasting Induces Stem Cell Regeneration, Restores Immune System

In the first evidence of a natural intervention triggering stem cell-based regeneration of an organ or system, a study in the June 5 issue...

Shock And Age

The accumulation of misfolded protein marks the accrual of years as the body ages. Could heat shock proteins be used to reduce the effects of aging and diminish the risk of disease by untangling improperly folded proteins?

New Anti-Aging Pill Under Fire

A major new study claims the pricey supplement TA-65 may turn back the clock, all the way down to our DNA—but many scientists are brushing it off as snake oil. Thea Singer investigates. In an era of seemingly magical technology, the notion that scientists could develop a pill that might slow the aging process doesn’t seem that far-fetched.

Natural Cellular Antioxidant Declines With Age: Cell’s Reserve Fighting Force Diminished

When the body fights oxidative damage, it calls up a reservist enzyme that protects cells -- but only if those cells are relatively young, a study has found. Biologists at USC discovered major declines in the availability of an enzyme, known as the Lon protease, as human cells grow older.

Study Links Aging to Oxidative Damage in Mitochondria

As long as humans have been alive, they've been seeking ways to extend life just a little longer. So far no one has found...

Glucosamine Increases Life Span 10 Percent by Mimicking Low-Carb Diet in...

Glucosamine has been freely available in drugstores for many decades. It is widely used to treat arthritis and to prevent joint degeneration. Moreover, glucosamine...

Men Twice as Likely to Die After Hip Fracture

Alarming new data published today by the International Osteoporosis Foundation (IOF), shows that one-third of all hip fractures worldwide occur in men, with mortality...

Extending “Healthspan” by Controlling Age-Related Inflammation

Inflammation is the common denominator of many chronic age-related diseases such as arthritis, gout, Alzheimer's, and diabetes. But according to a Yale School of...

Biologists Delay Aging, Increase Lifespan 30% in Animal Model, Suggest Role...

Biologists have identified a gene that can slow the aging process when activated remotely in key organ systems. The life scientists, working with fruit...

Lactate In The Brain Reveals Aging Process

Researchers at Karolinska Institutet have shown that they may be able to monitor the aging process in the brain, by using MRI technique to measure the brain lactic acid levels. Their findings suggest that the lactate levels increase in advance of other aging symptoms, and therefore could be used as an indicator of aging and age-related diseases of the central nervous system.

The Link Between Circadian Rhythms and Aging

Gene Associated With Longevity Also Regulates the Body's Circadian Clock Human sleeping and waking patterns are largely governed by an internal circadian clock that corresponds...
