A genetically engineered herpes simplex virus, primarily known for causing cold sores, may help keep arteries ?free-flowing? in the weeks following angioplasty or stent placement for patients, according to research published early in the online edition of PNAS (Proceedings of the National Academy of Sciences of the United States of America).
Breast cancer patients who possess one of the so-called “breast cancer” or BRCA genetic mutations do not have a higher risk of dying than patients with no BRCA mutations, according to a detailed study by researchers at the Technion-Israel Institute of Technology and the University of Toronto.
A new study to be published in the July issue of the Journal of the American College of Surgeons shows that one academic medical center recouped its investment in electronic health records within 16 months. The new analysis counters concerns of health care providers reluctant to invest in electronic medical records systems.
When a cell is seriously stressed, say by a heart attack, stroke or cancer, a protein called Bak just may set it up for suicide, researchers have found.
Hispanic women with hypertension and coronary artery disease respond better to drug regimens aimed at controlling high blood pressure than non-Hispanic white women, University of Florida researchers report.
For centuries people have been puzzled by the inevitability of human aging. For most of the second half of the twentieth century, aging remained a mystery, or an unsolved biological problem. At the end of the 20th century, a remarkable scientific discovery emerged.
A new type of cone-beam computed tomography (CBCT) imaging system could enable surgeons and interventional radiologists to perform minimally invasive procedures under the guidance of 3-D images acquired during surgery with sub-millimeter spatial resolution.
A solid-state x-ray image intensifier (SSXII), now in development, should greatly improve the spatial resolution of medical x-ray imaging.
By borrowing techniques used in telecommunications technology, computed tomography (CT) scanners may eventually see data collection speeds increase by hundreds of times, leading to better images, faster imaging procedures, and potentially lower x-ray exposures.
Measuring levels of a chemical found in blood offers the best indicator yet of the amount of fat surrounding abdominal organs, according to a new study of lean and obese individuals reported in the July issue of Cell Metabolism, a publication of Cell Press.
