WINSTON-SALEM -- The brains of some people who read poorly -- especially people with dyslexia -- differ physiologically from normal readers, according to pioneering work at the Wake Forest University Baptist Medical Center.
Scientists at Wake Forest University Baptist Medical Center report today that they have found another way to shut down the doorway for HIV-1 to invade two types of white blood cells -- lymphocytes and macrophages. In a report in the Oct 14 issue of the Proceedings of the National Academy of Sciences, Si.-Yi Chen, M.D., Ph.D., assistant professor of cancer biology, and his colleagues describe how they have inactivated the most frequently used co-receptor -- docking site -- for HIV-1 viruses on the surface of both macrophages and lymphocytes, resulting in immunity of those macrophages and lymphocytes to HIV-1 infection.
Dr. James F. Toole of Wake Forest University Baptist Medical Center has been elected president of the World Federation of Neurology for a four-year term, defeating four other candidates.
Winston-Salem -- In what could be the most exciting advance in the treatment of AIDS to date, Bowman Gray School of Medicine scientists today reported a novel way to block the deadly HIV virus from ever invading white blood cells.
Ultrasound is more than 90 percent effective in distinguishing between ischemic and hemorrhagic stroke under emergency treatment conditions, a group of German neurologists report.
Ultrasound contrast agent reflects the signal from transcranial ultrasound probe, illuminating blocked portion of the middle cerebral artery causing an ischemic stroke, German doctors report. Doctors dissolve the stroke-causing clot with 100 milligrams of the thrombolytic rTPA, preventing stroke damage.
Researchers from Brazil and Canada reported today (Aug. 14) that a combination of transcranial Doppler ultrasound and duplex carotid ultrasound can accurately measure the degree of blockage in the carotid arteries that serve the brain, averting the need for cerebral angiography, a risky technique that can provoke a stroke.
Researchers from throughout the world will be coming to Winston-Salem next week to report dramatic and newsworthy findings from a broad spectrum of investigations at International Neurosonology '97 -- only the second time the meeting has been held in the United States.
Abnormalities measured on 3D reconstructions of ultrasound images are more reliable and easier to reproduce than on two-dimensional (2D) ultrasound, researchers from Germany reported today.
Patients suffering from bacterial endocarditis, a heart infection, remain at risk for stroke and other cerebral complications far longer than previously known, a German doctor reported. He said 80 percent of the patients he studied continued to have microembolisms in their brains up to four weeks after having been treated with antibiotics.
Low-frequency ultrasound speeds the clot-busting power of thrombolytic drugs and may allow physicians to dissolve blood clots deep within the brain with lower doses of medication -- reducing the risk of bleeding and other complications, Japanese scientists report.
Ultrasound is a valuable imaging technique for evaluating patients with whiplash and low back pain, investigators at Ultrasound Diagnostic Services Inc. in Cleveland, Ohio, report.
To understand more about back pain, researchers are using sonography to study healthy people who are pain-free, and confirming that ultrasound can be used to map the major landmarks of the spine.
In a finding that could have implications for millions of Americans, particularly those who are diabetic, medical researchers reported today that whites and Hispanics who are insulin resistant are at a higher risk of developing atherosclerosis that can lead to stroke and heart attack.
A content analysis of 518 televised music videos from four major cable networks showed 25.7 percent of MTV videos portrayed use of tobacco, most often by the lead singer, according to a study conducted by faculty from three medical centers.
A combination of a blood test and ultrasound could give physicians a better picture of who is at risk of a fatal or disabling stroke, researchers in Denmark reported today (Aug. 16).
