'Living Off The Land' Associated With Lower Age-Related Blood Pressure Increases
Hunter-gatherers and forager-horticulturalists who live off the land and grow what they need to survive have lower age-related increases in blood pressure and less risks of atherosclerosis, according to two new studies in the American Heart Association journal Hypertension. High blood pressure and atherosclerosis - a disease in which arteries stiffen and fill with plaque - increase with age in the United States and other countries, raising risks for heart attack, stroke, kidney disease and death...

Nanotechnology In Brain Treatment Research
Researchers at Purdue University are working with the U.S. Army and neurosurgeons at the Walter Reed National Military Medical Center to create a new type of bioactive coating for stents used to treat brain aneurisms including those caused by head trauma from bomb blasts. Stents coated with a bioactive coating might be inserted at the site of an aneurism to help heal the inside lining of the blood vessel, said Jean Paul Allain, an associate professor of nuclear engineering. Aneurisms are saclike bulges in blood vessels caused by weakening of artery walls... (Source: Health News from Medical News Today)
