Although chemotherapy is used to kill cancer cells, it can also have a strong toxic effect on normal cells such as bone marrow and blood cells, often limiting the ability to use and manage the chemotherapy treatment. Researchers at Fred Hutchinson Cancer Research Center reported at today's annual meeting of the American Society of Gene and Cell Therapy in Seattle that one possible approach to reduce this toxic effect on bone marrow cells is to modify the cells with a gene that makes them resistant to chemotherapy. http://medicalxpress.com/news/2011-05-gene-modified-stem-cells-bone-marrow.html Cancer Sat, 21 May 2011 05:36:52 EST news225174980 Neuroeconomic research at the University of Pennsylvania has conclusively identified a part of the brain that is necessary for making everyday decisions about value. Previous functional magnetic imaging studies, during which researchers use a powerful magnet to determine which parts of a subjects brain are most active while doing a task, have suggested that the ventromedial frontal cortex, or VMF, plays an evaluative role during decision making. http://medicalxpress.com/news/2011-05-region-brain-decisions-economic.html Neuroscience Wed, 18 May 2011 09:38:23 EST news224930251
