(Medical Xpress)—The use of a new brain tumor-targeting contrast agent that differentiates between normal and cancer cells in conjunction with a high-powered microscopy system could potentially lead to a method of more precise neurosurgery for brain tumors, according to research paper published as a cover story in the December issue of Translational Oncology. Developed by researchers in the Department of Biomedical Engineering (BME) at Stony Brook University, the contrast agent adheres to a molecular marker of medulloblastoma, a form of brain cancer, and can be seen by the optical microscope system, also developed by the research team. http://medicalxpress.com/news/2013-01-method-brain-tumors-neurosurgery.html Cancer Thu, 10 Jan 2013 06:42:01 EST news277022515 (Medical Xpress)—Using a super-resolution fluorescent microscope, medical scientists are a step closer to understanding why and how human immune cells decide to activate or not, thus enabling or preventing disease taking hold in the body. http://medicalxpress.com/news/2012-12-super-resolution-microscope-human-t-cells-life.html Immunology Mon, 03 Dec 2012 07:31:30 EST news273742283 Routine smear tests have considerably reduced the number of cases of cervical cancer, but despite intensive screening 250 women in Sweden still die from the disease every year. Researchers at Sahlgrenska Academy, University of Gothenburg, Sweden, have developed new methods of minimising the number of missed cases and making diagnosis more reliable. http://medicalxpress.com/news/2012-11-cervical-cancer.html Cancer Fri, 23 Nov 2012 12:52:25 EST news272897537
