A Case Western Reserve University chemistry professor has begun imbedding magnetic nanoparticles in the toughest of plastics to understand why more than 40,000 Americans must replace their knee and hip replacements annually. http://medicalxpress.com/news/2013-02-effort-hips-knees-bad.html Medical research Mon, 04 Feb 2013 15:52:14 EST news279215497 In a development that could lead to faster and more effective toxicity tests for airborne chemicals, scientists from Rice University and the Rice spinoff company Nano3D Biosciences have used magnetic levitation to grow some of the most realistic lung tissue ever produced in a laboratory. http://medicalxpress.com/news/2013-01-magnetically-levitated-tissues-toxicity.html Medical research Thu, 24 Jan 2013 16:38:46 EST news278267911 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
