Exercise increases brain growth factor and receptors, prevents stem cell drop in middle age

A new study confirms that exercise can reverse the age-related decline in the production of neural stem cells in the hippocampus of the mouse brain, and suggests that this happens because exercise restores a brain chemical which promotes the production and maturation of new stem cells.

Potential new therapeutic targets for rejuvenating the aged immune system

In the November 15th issue of G&D, Dr. Kenneth Dorshkind and colleagues at the David Geffen School of Medicine (UCLA) have identified two genes - p16(Ink4a) and Arf - that sensitize lymphoid progenitor cells to the effects of aging, and confer resistance to leukemogenesis.

Hope for treating relapse to methamphetamine abuse

"Reinstatement of drug-seeking behavior after an extended period of abstinence is the number-one cause of drug-addiction relapse," said Brookhaven neuroanatomist Stephen Dewey, who led the research team. "This animal study suggests that vigabatrin could potentially prevent human methamphetamine addicts from relapsing."

Blood levels of resistin a new biomarker for heart failure

Blood levels of resistin, a hormone produced by fat cells, can independently predict an individual's risk of heart failure, cardiologists at Emory University School of Medicine have found.

NEI releases complete data from age-related eye disease study

The National Eye Institute (NEI), part of the National Institutes of Health (NIH), announces the release of more than 10 years of data collected during the Age-Related Eye Disease Study (AREDS), which looked at the progression of age-related macular degeneration and age-related cataract in 4,757 adults aged 55 to 80.
