Virginia Tech released today results from the first study ever to instrument child football helmets. Youth football helmets are currently designed to the same standards as adult helmets, even though little is known about how child football players impact their heads. This is the first study to investigate the head impact characteristics in youth football, and will greatly enhance the development of improved helmets specifically designed for children. http://medicalxpress.com/news/2011-10-virginia-tech-biomedical-child-football.html Health Tue, 18 Oct 2011 02:21:53 EST news238123290 Technology developed by researchers at The University of Texas at Austin could significantly reduce the time and cost to finding a cure for Alzheimer's disease and help answer one of the greatest biological questions: why do we age? http://medicalxpress.com/news/2011-10-reversing-aging.html Medical research Mon, 17 Oct 2011 13:51:55 EST news238078304 Columbia Engineering researchers have developed a new technique to reach neurons through the blood-brain barrier (BBB) and deliver drugs safely and noninvasively. Up until now, scientists have thought that long ultrasound pulses, which can inflict collateral damage, were required. But in this new study, the Columbia Engineering team show that extremely short pulses of ultrasound waves can open the blood-brain barrier -- with the added advantages of safety and uniform molecular delivery -- and that the molecule injected systemically could reach and highlight the targeted neurons noninvasively. http://medicalxpress.com/news/2011-09-short-ultrasound-pulses-neurons-blood-brain.html Medical research Mon, 19 Sep 2011 15:00:22 EST news235662789 (Medical Xpress) -- Researchers have created and tested miniature devices that are implanted in tumors to generate oxygen, boosting the killing power of radiation and chemotherapy. http://medicalxpress.com/news/2011-08-tiny-oxygen-boost-effectiveness-anticancer.html Cancer Wed, 31 Aug 2011 07:26:04 EST news233994327 New research from the Jefferson Heart Institute shows that patients in the United States who receive cardiac electrophysiological devices (CIEDs), including permanent pacemakers and implantable cardioverter-defibrillators (ICDs) are now at greater risk of contracting an infection over the life span of the device. http://medicalxpress.com/news/2011-08-infection-patients-cardiac-electrophysiological-devices.html Cardiology Mon, 22 Aug 2011 16:25:47 EST news233249132 A new study into the causes of leakage in one of the heart's most complex valve structures could lead to improved diagnosis and treatment of the condition. http://medicalxpress.com/news/2011-08-vitro-tricuspid-valve-mechanics-uncovers.html Other Tue, 09 Aug 2011 10:10:13 EST news232102443 Every year, millions of people contend with lower back and neck discomfort.

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 Researchers from Aalto University have found the mechanism of action for cancer-cell-killing peptides.
