Blood protein offers clues to heart attack in seemingly healthy people
07-02-2007 · EurekAlert!
We've all wondered how a seemingly healthy person can actually be at high risk for heart disease or a heart attack. Now researchers have uncovered a new clue to this mystery. The culprit: myeloperoxidase, a protein secreted by white blood cells that both signals inflammation and releases a bleach-like substance that damages the cardiovascular system.

All itches not created equal -- Different parts of brain activated depending on cause
12-06-2006 · EurekAlert!
Different reactions in the brain to two common allergy triggers -- allergens (pollen and dust) and histamine (allergy cells within the body caused by foods, drugs or infection) -- may shed some light on the itch-scratch cycle. Allergen-induced itch intensity ratings were higher compared to histamine and perception of itch and changes in blood flow were significantly greater when allergen induced. Itch intensity and changes in blood flow were perceived to exist for significantly longer periods.

Memory tasks require more coordinated brain blood flow for people with high blood pressure
09-27-2007 · EurekAlert!
Blood flow to the parts of the brain that support memory function differs between people with high blood pressure and those with normal blood pressure, and this difference seems to increase when high blood pressure is treated with medications, researchers reported today at the American Heart Association's 61st Annual Fall Conference of the Council for High Blood Pressure Research.

Undernourished stroke patients may have more complications, worse outcomes
01-14-2008 · EurekAlert!
Patients who are undernourished when they enter the hospital with an acute ischemic stroke -- the most common type of stroke, in which blood flow to the brain is blocked -- are likely to remain undernourished in the hospital and may have worse clinical outcomes, according to a report in the January issue of Archives of Neurology, one of the JAMA/Archives journals.

Technology could enable computers to 'read the minds' of users
10-01-2007 · EurekAlert!
Tufts researchers are developing techniques that could allow computers to respond to users' thoughts of frustration or boredom (too much or too little work) by applying functional near-infrared spectroscopy technology, which uses light to monitor brain blood flow as a proxy for user workload stress. Applying this noninvasive, portable imaging technology in new ways, the researchers hope to gain real-time insight into the brain's emotional cues.
