The study's results will be presented today during the American Society for Radiation Oncology (ASTRO) annual meeting in Chicago. http://www.physorg.com/news176395872.html Medicine & Health Mon, 02 Nov 2009 16:30:01 EST news176395872 Researchers at the University of Pittsburgh School of Medicine and the National Cancer Institute (NCI), part of the National Institutes of Health, may be hot on the heels of a Holy Grail of cancer therapy: They have found a way to not only protect healthy tissue from the toxic effects of radiation treatment, but also increase tumor death. The findings appear today in Science Translational Medicine. http://www.physorg.com/news175355067.html Medicine & Health Wed, 21 Oct 2009 15:00:03 EST news175355067 (PhysOrg.com) -- A new study by Cornell researchers uncovers the details of how the world's toughest bacterium survives lethal radiation exposure. http://www.physorg.com/news175197704.html Biology Mon, 19 Oct 2009 19:03:16 EST news175197704 Completing an 18-month mission orbiting the Earth more than 6,000 times on-orbit the International Space Station (ISS), the Optical Reflector Material Experiment (ORMatE-1) returns to Washington, D.C., to NRL's Electronics Science and Technology Division to begin experiment testing and analysis. http://www.physorg.com/news173532760.html Space & Earth Wed, 30 Sep 2009 12:36:05 EST news173532760 Radiologists have discovered that prospective electrocardiogram (ECG) gating allows them to significantly reduce the patient radiation dose delivered during computed tomography (CT) angiography, a common noninvasive technique used to evaluate vascular disease, according to a study published in the October issue of the American Journal of Roentgenology (AJR). http://www.physorg.com/news172733633.html Medicine & Health Mon, 21 Sep 2009 08:40:04 EST news172733633 A research project looking for ways to reduce bone loss in astronauts may yield methods of improving the bone health of cancer patients undergoing radiation treatment. http://www.physorg.com/news172237370.html Medicine & Health Tue, 15 Sep 2009 13:00:07 EST news172237370 Patients who have after-hour orthopaedic surgeries risk a slightly higher rate of necessary follow-up surgeries, according to a study published in the September 2009 issue of The Journal of Bone and Joint Surgery (JBJS). The data also suggests that patients whose surgeries took place during the day have the same healing, recovery time, and major complication rates as patients who have surgery after hours. http://www.physorg.com/news171039252.html Medicine & Health Tue, 01 Sep 2009 18:00:01 EST news171039252 Researchers from Boston University School of Medicine (BUSM) and collaborators have discovered and analyzed several new compounds, collectively called the ''EUK-400 series,'' which could someday be used to prevent radiation-induced injuries to kidneys, lungs, skin, intestinal tract and brains of radiological terrorism victims. The findings, which appear in the June issue of the Journal of Biological Inorganic Chemistry, describe new agents which can be given orally in pill form, which would more expedient in an emergency situation. http://www.physorg.com/news166441850.html Chemistry Fri, 10 Jul 2009 10:51:12 EST news166441850 While screening for possible pulmonary emboli using pulmonary CT angiography, a new study shows that radiologists can effectively lower the patient radiation dose by approximately 44% and improve vascular enhancement without deterioration of image quality, according to a study performed at Brigham and Women's Hospital and Harvard Medical School, Boston, MA. http://www.physorg.com/news165590420.html Medicine & Health Tue, 30 Jun 2009 14:50:01 EST news165590420 Patients with thyroid cancer who have previously been exposed to radiation -for example, in the workplace, through environmental exposure or for treatment of acne or another condition -appear to have more aggressive disease and tend to have worse outcomes in the long term, according to a report in the April issue of Archives of Otolaryngology-Head & Neck Surgery, one of the JAMA/Archives journals. http://www.physorg.com/news159474058.html Medicine & Health Mon, 20 Apr 2009 19:21:17 EST news159474058 Resveratrol, the natural antioxidant commonly found in red wine and many plants, may offer protection against radiation exposure, according to a study by the University of Pittsburgh School of Medicine. When altered with acetyl, resveratrol administered before radiation exposure proved to protect cells from radiation in mouse models. The results of the research will be presented during the American Society for Therapeutic Radiology and Oncology's (ASTRO) 50th Annual Meeting in Boston. http://www.physorg.com/news141407675.html Medicine & Health Tue, 23 Sep 2008 16:54:35 EST news141407675
