A team of University of California, San Diego physicists and neuroscientists has discovered a bottleneck in the network of blood vessels in the brain that makes it vulnerable to strokes. The finding may explain the origin of the puzzling damage to the brain?s gray matter often detected in brain scans, especially among the elderly.
Neuroscientists at Duke University have mapped the timing and sequence of neural activations that unfold in the brain when people focus their attention on specific locations in their visual fields.
A University of Vermont study suggests that the astrocytic BK channel is an important participant in the cellular process responsible for signaling regional blood flow changes in the brain, providing a new key to understanding such disorders as stroke, migraine and Alzheimer’s disease.
Uric acid is commonly associated with the excruciatingly painful joint disease known as gout, but it can also play a crucial role in the treatment of spinal cord injury and other central nervous system disorders, such as stroke, multiple sclerosis and Parkinson’s disease, according to Rutgers’ Bonnie Firestein.
In work with mice, researchers at the University of California, San Diego, School of Medicine discovered a factor that could be responsible for many unexplained cases of elevated triglyceride levels.
Researchers at the Harvard School of Public Health (HSPH), Beth Israel Deaconess Medical Center and Dutch research institute TNO Quality of Life and Wageningen University, the Netherlands, found that, among hypertensive men, moderate alcohol consumption was associated with a decreased risk of fatal and non-fatal heart attack.
Undernourished women who take a vitamin and mineral supplement while pregnant may be less likely than women taking only iron and folic acid supplements to have babies weighing less than 2,500 grams, and their newborns may be less likely to have morbidity in the first seven days of life, according to a report in the January issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.
A new study found that men with high blood pressure can have one or two drinks a day without increasing risk for heart attack or stroke. It is known that moderate consumption of alcohol lowers risk of heart disease.
Heart disease hits Americans who live in southern states harder than residents of other regions of the country, according to the latest annual survey of cardiovascular disease in the United States.
Two novel treatments — a basic compound found in every cell in the body and an extract of green tea — may prevent brain damage caused from stroke, according to two studies in rats led by a researcher at the San Francisco VA Medical Center.
