University of Pennsylvania School of Medicine Using a University of Pennsylvania-designed device to noninvasively and continuously monitor cerebral blood flow (CBF) in acute stroke patients, researchers from Penn Medicine and the Department of Physics & Astronomy in Penn Arts and Sciences are now learning how head of bed (HOB) positioning affects blood flow reaching the brain. Most patients admitted to the hospital with an acute stroke are kept flat for at least 24 hours in an effort...

Dl-3n-butylphthalide can effectively treat cerebral ischemia; however, the mechanisms underlying the effects of dl-3n-butylphthalide on microcirculation disorders following diffuse brain injury remain unclear. According to a study by Prof. Jianmin Li and team from Hebei United University of China, models of diffuse brain injury were established in Sprague-Dawley rats with the vertical impact method, and dl-3n-butylphthalide at 80 and 160 mg/kg was given via intraperitoneal injection...

How the intricate network of blood vessels forms within the brain has long fascinated biologists. Though the human brain comprises only 2 percent of body weight it receives up to 15 percent of the cardiac output through this network, or vessel vasculature. The vasculature in the human brain consists of a complex branching network of blood vessels, in total some several hundred miles in length. The network is formed so as to distribute blood efficiently to all brain regions, and abnormalities...

A new monitoring method and blood test may provide early warnings when a child's brain isn't getting enough blood during heart surgery, according to new research presented during the American Heart Association's Emerging Science Series webinar. Brain injury occurs in 30 percent to 70 percent of infants and children undergoing repair of congenital heart defects. A congenital heart defect is a heart abnormality present at birth. Out of 1,000 live births in the United States, about 8 babies...

Researchers in Germany have used a magnetic resonance imaging (MRI) technique called continuous arterial spin labeling (CASL) to map cerebral blood flow patterns in schizophrenic patients quickly and without using radiation or contrast agents. Their findings appear in the online edition and July printed issue of the journal Radiology. "Arterial spin labeling is a powerful technique that can help reduce the cost and complexity of examinations," said the study's lead author, Lukas Scheef, M.D.,...

A new study shows that altered blood flow in the brain due to high blood pressure and other conditions may lead to falls in elderly people. The research is published in the May 18, 2010, issue of Neurology®, the medical journal of the American Academy of Neurology. Each year, unintentional falls in the United States account for more than 16,000 deaths and 1.8 million emergency room visits. "At age 60, 85 percent of people have a normal walking ability. However, by age 85,...

The organs of the inner ear have a direct effect on brain blood flow, independent of blood pressure and CO2 levels in the blood. Researchers writing in the open access journal BMC Neuroscience used a series of human centrifuge experiments to investigate the effects of stimulation of the otoliths and semi-circular canals on cerebrovascular response. Dr. Jorge Serrador, from Harvard Medical School, worked with a team of researchers, including NASA scientists, to carry out the tests. He said,...
