When a stroke affects the language areas in the left side of the brain, the right side takes over and learns how to perform language tasks, according to research at Washington University School of Medicine in St. Louis. The study found that patients right side of the brain is more active than normal during a verbal language task, and that the right sides activity decreases with practice, similar to what happens on the left side of the brain in healthy individuals.

Finding may lead to new treatments for neurologic disease and nerve injury
Why do some nerve cells survive and regrow after injury while others shrink away and die? A new discovery by researchers at Massachusetts General Hospital (MGH) shows that the expression of a particular gene may be responsible for protecting neurons from death. The results, published in the September 26 issue of Neuron, could lead the way for new treatment strategies for a variety of neurological diseases.
An international team of scientists have today reported the discovery of a protein, called DIR1, that is a key step in the pathways that enable plants to protect themselves against disease. DIR1 is involved in the transmission of a warning signal from plant cells infected by disease. The signal alerts cells, in areas remote from the infected site, that the plant is under attack and switches on defence mechanisms that prevent the disease establishing further infection sites. The report, from scientis
More than one-third of patients undergoing chemotherapy at risk for heart failure
Researchers at The University of Texas M. D. Anderson Cancer Center have found that cancer patients who develop heart failure as a result of chemotherapy treatment can be effectively treated, with the condition potentially reversed, when standard medicated therapy for heart failure is utilized.
The findings were presented today at the Sixth Annual Scientific Meeting of the Heart Failure Society
A new Scottish multi-million pound photonics company is geared up for the future of telecommunications after securing a seven figure private investment deal.
The investment has allowed Helia Photonics Ltd, a Heriot-Watt University spin-out to purchase the coatings division of Terahertz Photonics in a technology transfer deal, and say they are already in discussions with a European partner over a major contract.
Helia Photonics CEO, David Hamilton, says they will be concentrating on
Losartan tops beta blocker in patients with high top number blood pressure
A drug that reduces high blood pressure in people with a form of the disease thats common later in life also cuts their risk of stroke and death, and does it better than another hypertension drug, a new study finds.
In the Sept. 25 issue of the Journal of the American Medical Association, an international team of researchers report that patients over age 55 who took a drug called los
