Stroke News and Research

RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

Genes that protect against atherosclerosis identified

One way of combating atherosclerosis is to reduce levels of “bad cholesterol” in the blood. Scientists at the Swedish medical university Karolinska Institutet have now identified the genes that bring about this beneficial effect.

How diabetes drives atherosclerosis

Researchers have discovered how diabetes, by driving inflammation and slowing blood flow, dramatically accelerates atherosclerosis, according to research to be published in the March 14 edition of the journal Circulation Research. Experts once believed that atherosclerosis, or hardening of the arteries, developed when too much cholesterol clogged arteries with fatty deposits called plaques.

Structure reveals how cells 'sugar-coat' proteins - process essential to many proteins' functions can lead to disease when gone awry

Biologists at the U.S. Department of Energy's Brookhaven National Laboratory, Stony Brook University, and the University of Wurzburg, Germany, have deciphered the structure of a large protein complex responsible for adding sugar molecules to newly formed proteins - a process essential to many proteins' functions.

Low dose inhaled corticosteroids improve lung function in mild asthma patients

A study by the Woolcock Institute of Medical Research in Sydney is the first to demonstrate that in patients with very mild or well-controlled asthma, regular treatment with low dose ICS leads to significantly better day-to-day lung function.

Post-stroke clot-busting therapy beneficial for patients on aspirin

Patients given a clot-busting drug following stroke appear to have better outcomes if they were already taking anti-platelet medications, despite an apparent increased risk for bleeding in the brain, according to an article posted online that will appear in the May 2008 print issue of Archives of Neurology.

Magnesium linked to lower risk for some strokes in male smokers

Male smokers who consume more magnesium appear to have a lower risk for cerebral infarction, a type of stroke that occurs when blood flow to the brain is blocked, according to a report in the March 10 issue of Archives of Internal Medicine.

Researchers discover molecular pathway in blood vessels that controls blood pressure and vascular function

University of Iowa researchers have identified a molecular pathway in blood vessels that controls blood pressure and vascular function and may help explain why certain drugs for type II diabetes also appear to lower patients' blood pressure.
