Cancer revealed: New $10M grant establishes cancer imaging center
...in its role of detecting and leading the repair of damaged
DNA. The p53 protein builds up in cells whose DNA has been damaged, so a test that looks for a buildup of p53 (through a buildup of luciferase) could help evaluate everything from the protective effect of new sunscreens to the mutation-causing potent...

Kidney disease in diabetics relates to insulins effectiveness, say Pittsburgh researchers
...ease, in which the kidneys' tiny blood vessels are damaged
and unable to filter wastes and excess water from the blood. Untreated, nephropathy leads to end stage renal disease (ESRD), in which the kidneys' entire filtration system closes down and the kidneys fail to function. A patient with ESRD requires dia...
Jefferson scientist links gene to alcoholic's vulnerability to heart failure
...drink much less, yet they can have hearts that are damaged
and perform worse. Dr. Rubin and his colleagues wondered if genetics contributed to this difference. They studied 30 Spanish men who were alcoholics and came into a hospital emergency room or clinic in Barcelona with congestive heart failure. The re...
Rutgers researcher finds brain connections may reorganize in Parkinson's disease
...ical clues that may explain why parts of the brain damaged
by Parkinson's disease, specifically those that control sensory-guided movements, aren't repaired by dopamine replacement therapy. Parkinson's is the second most common neurodegenerative disease affecting older people in the United States and is cha...
Gene therapy promising for preventing restenosis

blood vessels, they could control free radical damage and thereby short-circuit the process that leads to restenosis. In the study they tested this hypothesis by using a deactivated virus to deliver EC-SOD to cells in the arterial walls of animals. ...

Shocking the heart after prolonged cardiac arrest may be harmful, say Pitt researchers
...uscitate because the injured heart is only further damaged
by shocking it. This evidence suggests we should try other treatment options before defibrillation," stated James Menegazzi, Ph.D., research professor of emergency medicine at the University of Pittsburgh School of Medicine and lead author of the stu...

Carcinogen in cigarettes causes mutation linked to lung cancer
