Dietary agents in red chili pepper and vegetables linked to cancer prevention

Two new studies suggest that vegetables such as broccoli and spices like red chili pepper, may provide a cancer-fighting benefit by slowing or preventing the growth of cancerous tumor cells. The findings, being presented at the annual meeting of the American Association for Cancer Research held April 16 to 20 at the Anaheim Convention Center in Anaheim, Calif., looked at the effect of these dietary agen

A national survey has found that after a long, slow downward trend alcohol-impaired driving has recently increased significantly. From 1993 to 1997 the estimated annual number of episodes of alcohol-impaired driving (AID) declined at a rate of a little more than one percent per year, from 123 million to 116 million. From 1997 to 1999, however, it increased 37 percent, from 116 million to 159 million. It stayed at that increased rate in 2002.

“Family members continue to be the primary source of nurturance and safety for those who do this high-stress job,” says Cheryl Regehr, U of T professor of social work and director of the university’s Centre for Applied Social Research. “If they don&#146

Results suggest CT perfusion improves outcomes

Interventional neuroradiologists at West Virginia University School of Medicine and Hospitals today presented the largest study to date on the utility of computed tomography (CT) perfusion imaging of the brain in determining and predicting stroke outcomes. Results will help better identify patients who are suitable candidates for treatment utilizing either clot busting medicines or clot retrieval devices. The research was presented to

This study was aimed at the detection of lung cancer in its early stages amongst high-risk persons by means of Computerised Axial Tomography (CAT).

Currently, 85% of cases are diagnosed at a late stage, which considerably reduces the rate of cure.

Lung cancer is the most common carcinoma in western countries and the one that causes most deaths; more than those caused by breast cancer, cancer of the colon and prostate cancer put together.
