NIH announces phase III clinical trial of creatine for Parkinson's disease

...idant that prevents damage from compounds that are harmful to cells in the brain. In a mouse model of PD, creatine is able to prevent loss of the cells that are typically affected. "Creatine, or any compound that may slow the progression of PD, could have very important long-term benefits for people who ...

Antibody signal may redirect inflammation to fuel cancer

...t antibody-producing B cells are essential for the harmful redirection of the leukocyte response. The finding startled many in the field because the B cells do not act at the site of inflammation where the leukocytes are located, so they apparently send the crucial signals remotely through the blood’s serum....

New cigarette designs don't offer lower predicted cancer risks

...ows that simply lowering the levels of a few known harmful compounds from tobacco smoke may not significantly reduce the risks of smoking," she said. Pankow's group examined carcinogen deliveries from 26 brands of conventional "regular," "light" and "ultralight" cigarettes. Using U.S. Environmental Protec...

Scientists find new genes for Crohn's disease

... an individual's ability to respond effectively to harmful microbes influences his or her susceptibility to the disease. "We propose that genetic variation in the ATG16L1 gene leads to alterations in how the body uses autophagy and therefore may result in increased persistence of [toxic] cellular and bact...
