Scientists at the Gladstone Institutes have gotten us one step closer to understanding and overcoming one of the least-understood mechanisms of HIV infection—by devising a method to precisely track the life cycle of individual cells infected with HIV, the virus that causes AIDS. http://medicalxpress.com/news/2012-09-scientists-technique-decipher-dormant-aids.html HIV & AIDS Tue, 11 Sep 2012 12:54:58 EST news266586891 University of British Columbia researcher Hongshen Ma has developed a simple and accurate device to study malaria, a disease that currently affects 500 million people per year worldwide and claims a million lives. http://medicalxpress.com/news/2012-02-lab-chip-device-malaria.html Medical research Tue, 28 Feb 2012 13:04:26 EST news249656536 Samuel K. Sia, assistant professor of biomedical engineering at Columbia Engineering, has developed an innovative strategy for an integrated microfluidic-based diagnostic device—in effect, a lab-on-a-chip—that can perform complex laboratory assays, and do so with such simplicity that these tests can be carried out in the most remote regions of the world. In a paper published in Nature Medicine online on July 31, Sia presents the first published field results on how microfluidics—the manipulation of small amounts of fluids—and nanoparticles can be successfully leveraged to produce a functional low-cost diagnostic device in extreme resource-limited settings. http://medicalxpress.com/news/2011-07-hand-held-lab-on-a-chip-blood.html Other Sun, 31 Jul 2011 13:00:09 EST news231309845 A team of engineers and scientists at the University of British Columbia has developed a device that can be implanted behind the eye for controlled and on-demand release of drugs to treat retinal damage caused by diabetes. http://medicalxpress.com/news/2011-06-drug-delivery-device-diabetes-related-vision.html Medical research Thu, 30 Jun 2011 11:16:43 EST news228651353
