Since there is evidence that both antioxidants and calorie restriction increase lifespan and reduce aging-related diseases, Du...

Pesticides may promote Parkinson's disease and exercise may offer protection

...s studying Parkinson's and other neurodegenerative diseases is programmed (or apoptotic) cell death, which is known to occur in these diseases. Przedborski and his colleagues recently investigated whether the COX-2 protein is involved in the apoptotic death of nerve cells in Parkinson's disease. Using the MPT...

NIH funds rare childhood disease to provide insights into the origins of adult cancer

...nded with Drs. Vlachos and Lipton. While childhood diseases were once considered to hold little relevance to adult medicine, researchers are now learning otherwise. To illustrate, Dr. Vlachos cited how researchers have already discovered a genetic link between another rare childhood disease, Fanconi anemia, a...

Despite ever-growing knowledge about blood vessel formation (angiogenesis), scientists still know little about how the new blood vessels ...

Findings challenge Darwinian theory
