Colonoscopy represents one of the great weapons against cancer. In one step, a physician can find precancerous lesions in the colon and then cut them out, an on-the-spot intervention that prevents cancer from developing. Now, researchers at the Winthrop Rockefeller Cancer Institute and the University of Arkansas for Medical Sciences have developed another fiber optic technique that can detect lymph node metastases and destroy them on the spot, an action that could prevent the further spread of breast cancer, melanoma, or gastrointestinal cancer, all of which spread through the lymphatic system. http://www.physorg.com/news176116481.html Nanotechnology Fri, 30 Oct 2009 10:15:06 EST news176116481 Researchers led by Dr. Soheil Dadras at the Stanford University Medical Center have developed a novel methodology to extract microRNAs from cancer tissues. The related report by Ma et al, "Profiling and discovery of novel miRNAs from formalin-fixed paraffin-embedded melanoma and nodal specimens," appears in the September 2009 issue of the Journal of Molecular Diagnostics. http://www.physorg.com/news170599789.html Medicine & Health Thu, 27 Aug 2009 14:00:02 EST news170599789 (PhysOrg.com) -- Biomedical researchers at the University of Arkansas and University of Arkansas for Medical Sciences in Little Rock have developed a special contrast-imaging agent that is capable of molecular mapping of lymphatic endothelial cells and detecting cancer metastasis in sentinel lymph nodes. The new material could be used as a more efficient and less toxic alternative to nanoparticles and fluorescent labels used in the non-invasive, targeted molecular detection of normal cells, such as immune-related cells, and abnormal cells, such as cancer cells and bacteria. Findings were published in Nature Nanotechnology. http://www.physorg.com/news170521101.html Nanotechnology Wed, 26 Aug 2009 15:58:52 EST news170521101 Information obtained from a new application of photoacoustic tomography (PAT) is worth its weight in gold to breast cancer patients. http://www.physorg.com/news151072381.html Medicine & Health Tue, 13 Jan 2009 12:33:01 EST news151072381
