A new genetically engineered lab rat that has the full array of brain changes associated with Alzheimer's disease supports the idea that increases in a molecule called beta-amyloid in the brain causes the disease, according to a study, published in the Journal of Neuroscience. The study was supported by the National Institutes of Health. http://medicalxpress.com/news/2013-04-next-generation-alzheimer-disease.html Alzheimer's disease & dementia Tue, 09 Apr 2013 17:00:07 EST news284745162 The research was published early in the January issue of the journal Technology in Cancer Research and Treatment. The article describes experiments using ultrasonic molecular imaging (USMI) and Dynamic Contrast Enhanced-Perfusion Imaging (DCE-PI) to measure response to therapy for pancreatic cancer. http://medicalxpress.com/news/2013-02-preclinical-potential-technologies-response-cancer.html Cancer Wed, 20 Feb 2013 12:09:47 EST news280584578 Recent research has shown that there are new cells that develop in the heart, but how these cardiac cells are born and how frequently they are generated remains unclear. In new research from Brigham and Women's Hospital (BWH), researchers use a novel method to identify these new heart cells and describe their origins. http://medicalxpress.com/news/2012-12-birth-cardiac-cells.html Cardiology Wed, 05 Dec 2012 13:00:19 EST news273929710 Researchers have defined the gene responsible for a rare developmental disorder in children. The team showed that rare variation in a gene involved in brain development causes the disorder. This is the first time that this gene, UBE3B, has been linked to a disease. http://medicalxpress.com/news/2012-11-mice-mutations-gene-ube3b-rare.html Genetics Thu, 29 Nov 2012 12:05:40 EST news273413130 A study published this month by researchers at the University of Toronto and Toronto's Princess Margaret Hospital has shown that cells derived from the umbilical cord, "Human Umbilical Cord PeriVascular Cells" (HUCPVCs), are more effective in restoring heart function after an acute myocardial infarction (in common parlance, a heart attack) in a pre-clinical model than a similar cell population derived from bone marrow. http://medicalxpress.com/news/2012-11-umbilical-cord-cells-outperform-bone.html Medical research Thu, 15 Nov 2012 12:29:11 EST news272204941 Action is the foundational key to success. The triumph—or failure—of the UC clinical enterprise hinges equally on strict alignment of goals and priorities across the College of Medicine, UC Physicians and UC Health and a culture of personal accountability and collegiality among employees.  http://medicalxpress.com/news/2012-05-accountability-transparency-key-themes-uc.html Health Fri, 04 May 2012 09:30:01 EST news255341784
