(Medical Xpress)—A Yale-led team of researchers has uncovered a genetic malfunction that may lead to hardening of the arteries and other forms of cardiovascular disease. The study appears in the journal Cell Reports. http://medicalxpress.com/news/2012-11-loss-gene-trigger-cardiovascular-disease.html Medical research Fri, 30 Nov 2012 08:02:31 EST news273484929 In a study to investigate the detection by MRI of six kinds of positively-charged magnetic iron oxide nanoparticles designed to help monitor transplanted islet cells, a team of Japanese researchers found that the charged nanoparticles they developed transduced into cells and could be visualized by MRI while three kinds of commercially available nanoparticles used for controls could not. The study is published in a recent special issue of Cell Medicine [3(1)], now freely available on-line. http://medicalxpress.com/news/2012-10-mri-images-transplanted-islet-cells.html Medical research Mon, 01 Oct 2012 12:02:47 EST news268311760 Researchers from South Korea, Sweden, and the United States have collaborated on a project to restore neuron function to parts of the brain damaged by Huntington's disease (HD) by successfully transplanting HD-induced pluripotent stem cells into animal models. http://medicalxpress.com/news/2012-05-neuron-function-brains-huntington-disease.html Neuroscience Tue, 29 May 2012 11:41:22 EST news257510422 Biomedical engineers at Tufts University's School of Engineering have demonstrated the first all-polymeric bone scaffold material that is fully biodegradable and capable of providing significant mechanical support during repair. The new technology uses micron-sized silk fibers to reinforce a silk matrix, much as steel rebar reinforces concrete. It could improve the way bones and other tissues are repaired following accident or disease. http://medicalxpress.com/news/2012-04-high-strength-silk-scaffolds-bone.html Medical research Mon, 30 Apr 2012 15:50:02 EST news255019420 A new study published in the American Journal of Transplantation reveals that cigarette smoke exposure, in a cause-effect manner, results in graft rejection that would have been prevented by certain drug treatments. http://medicalxpress.com/news/2012-02-secondhand-results-graft.html Surgery Thu, 23 Feb 2012 12:05:23 EST news249221116
