Stony Brook University medical researcher developing new medication to prevent colon cancer

...diagnosed in its earliest stages because cancerous lesions in the colon grown slowly and often without symptoms. More than 148,000 new cases of colon cancer are diagnosed in the U.S. each year and more than 56,000 Americans die of the diseases annually, according to the American Cancer Society. In order t...

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

...isease," says Zigmond. "We've also shown that such lesions can be made in mice as well as in rats." In the second study, the rats were again forced to exercise. When all the animals' brains were analyzed for the presence of dopamine neurons, those that exercised showed a near-complete blockade of the toxic ...

The potential treatment strategy targets this final step of the metastatic cascade--the exit of the metastatic cells from the bloodstream. "We know that the normal blood vessel wall is one final barrier that metastatic ...

Research uncovers role of Apolipoprotein E in Alzheimer's disease

Abundance of myostatin in infected swine may result in reduced muscle mass

... experiment, but it did lead to the development of lesions that affected 8 percent of the total lung area in infected pigs. The finding was similar to earlier work in Johnson's laboratory. However, the introduction of PRRSV caused damage to the lungs from the bacterium to jump to 40 percent. "One thi...

Plant pathologists offer soybean rust identification and management tips
