Alagebrium may prevent arterial aging in patients with systolic hypertension

A compound called alagebrium, which is very similar to another used in anti-wrinkle creams, may be useful in reducing the deleterious effects of arterial aging in the majority of elderly Americans with systolic hypertension, a new study from researchers at Johns Hopkins shows.

Disruption of normal gene interaction linked to schizophrenia

Disruption of the normal interaction between the genes PRODH and COMT contributes directly to major symptoms of schizophrenia by upsetting the balance of the brain chemicals glutamate and dopamine, according to a group of investigators that includes a scientist now at St. Jude Children's Research Hospital.

Olfactory epithelium plays a critical role in pheromone detection

Howard Hughes Medical Institute researchers have discovered that pheromones essential for mating behavior in mice are recognized by the nose and not by the vomeronasal system, as researchers had long suspected.

Lifelong exercise decreases cellular aging in the brain

In the first study to show that lifelong exercise decreases cellular aging in the brain, scientists from the McKnight Brain Institute of the University of Florida say that moderately active rats have healthier DNA and more robust brain cells than their less active counterparts. The research was presented at the Society for Neuroscience's 35th annual meeting in Washington, D.C.
