New Tool Allows Early Prediction Of Patient's Stroke Outcome
Scientists have developed a new tool that may help physicians predict, during the first several hours a stroke patient is in the hospital, the degree of recovery the patient will eventually experience. The tool uses three factors for the accurate prediction of stroke outcome: measurement of brain injury using magnetic resonance imaging (MRI); the patient's score on the NIH stroke scale; and the time in hours from the onset of symptoms until the MRI brain scan is performed. more

Marijuana-Like Substances Linked To Cirrhosis Complications
Marijuana-like substances (endocannabinoids) intrinsic in animals and humans act at specific receptors on the blood vessel wall to produce vasodilation, the generalized blood vessel dilation seen in many patients with advanced liver cirrhosis, according to an article by George Kunos, M.D., Ph.D., and colleagues in the 1 July 2001, issue of Nature Medicine (Volume 7, Number 7; "Endocannabinoids: acting at vascular CB1 receptors mediate the vasodilated state in advanced liver cirrhosis"). Dr. Kunos, who serves as Scientific Director, Division of Intramural Clinical and Biological Research, NIAAA, performed some of the research under a National Heart, Lung, and Blood Institute (NHLBI) grant while at his previous position on the faculty of the Department of Medicine at Virginia Commonwealth University. more
