Brain Scans Reveal Distinctive Features In The Brain Structure Of Karate Experts Which Correlate With Punching Ability
Date: Aug-17-2012Karate experts are able to generate extremely powerful forces with their punches, but how they do this is not fully understood. Previous studies have found that the force generated in a karate punch is not determined by muscular strength, suggesting that factors related to the control of muscle movement by the brain might be important. The study, published in the journal Cerebral Cortex, looked for differences in brain structure between 12 karate practitioners with a black belt rank and an average of 13...
Particles That Shut Off Cancer Genes Could Also Allow Researchers To Screen Potential Drug Targets More Rapidly
Date: Aug-17-2012By sequencing cancer-cell genomes, scientists have discovered vast numbers of genes that are mutated, deleted or copied in cancer cells. This treasure trove is a boon for researchers seeking new drug targets, but it is nearly impossible to test them all in a timely fashion. To help speed up the process, MIT researchers have developed RNA-delivering nanoparticles that allow for rapid screening of new drug targets in mice...
Skin Cancer: Potential New Treatment Target Identified For Melanoma
Date: Aug-17-2012New research from Western University, Canada, has identified a potential new target for the treatment of melanoma, the deadliest of all skin cancers. Silvia Penuela and Dale Laird discovered a new channel-forming protein called Pannexin (Panx1) that is expressed in normal levels on the surface of healthy skin cells. But they found, in melanoma, Panx1 is over-produced to a pathological level. The researchers also discovered that if you reduce it or knock it down, the cell becomes more normal. The research is published in the August 17th issue of the Journal of Biological Chemistry...
Simulated Blood Flow Device Provides Evidence Of How Bloodstream Infections Begin
Date: Aug-17-2012New research may help explain why hundreds of thousands of Americans a year get sick - and tens of thousands die - after bacteria get into their blood. It also suggests why some of those bloodstream infections resist treatment with even the most powerful antibiotics. In a new paper in the Journal of Infectious Diseases, a team of University of Michigan researchers demonstrate that bacteria can form antibiotic-resistant clumps in a short time, even in a flowing liquid such as the blood...
The Fight Against Childhood Obesity Looks To School Food
Date: Aug-17-2012Childhood Obesity, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers, has published a special issue dedicated to the role that schools can and should play in providing and encouraging healthy nutrition and good eating habits to help stem the tide of the obesity epidemic in children and adolescents. The special issue provides comprehensive coverage of food policy, systems, and programs to improve food culture, practices, and nutrition standards in the school environment, and is available free on the Childhood Obesity website*...
By Studying Animal Health, Researchers Find Improved Ways For Developing, Testing Cancer Therapies
Date: Aug-17-2012A group of Kansas State University researchers has made valuable findings in the search for cancer's cure. While researching ways to improve animal health, the scientists -- Raymond "Bob" Rowland, a virologist and professor of diagnostic medicine and pathobiology, and Deryl Troyer, professor of anatomy and physiology -- have made two important discoveries that can also improve human health. Not only have they found pigs with severe combined immunodeficiency, or SCID, but they are also the first to discover the connection with human cancer, particularly melanomas and pancreatic cancers...
Focusing On Children Instead Of Relationship Problems Helps Separated Couples Parent Effectively, Civilly
Date: Aug-17-2012New research conducted at the University of Missouri offers hope for divorced parents and suggests hostile relationships can improve when ex-spouses set aside their differences and focus on their children's needs. "Most people falsely believe that, when people get divorced, they'll continue to fight, to be hostile," said Marilyn Coleman, Curators' Professor of Human Development and Family Studies at MU. "We found in our study that's not always true...
New American Chemical Society Podcast: A Non-Antibiotic Approach For Treating Urinary Tract Infections
Date: Aug-17-2012The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series describes a potential new approach for treating urinary tract infections (UTIs) - which affect millions of people annually - without traditional antibiotics. Because it involves non-antibiotic compounds, the approach would not contribute to the growing problem of antibiotic-resistant bacteria, or "superbugs." Based on a report by Beat Ernst, Ph.D., and colleagues in ACS' Journal of Medicinal Chemistry, the new podcast is available without charge...
Rehab For Stroke Victims: Therapy Combining Exercise And Neuroprotective Agent
Date: Aug-17-2012In a study published in the current issue of Restorative Neurology and Neuroscience scientists report that a therapy combining exercise with the neurovascular protective agent S-nitrosoglutathione (GSNO) improved recovery from stroke in a rat model. GSNO is a compound found naturally in the body and it has no known side effects or toxicity. "In our study, GSNO or motor exercise provided neuroprotection, reduced neuronal cell death, maintained tissue structure, and aided functional recovery by stimulating the expression of neuronal repair mediators," says lead investigator Avtar K...
Yoga Could Be A Cost-effective Treatment For Back Pain
Date: Aug-17-2012According to research published in Spine, the yoga intervention program called 'Yoga for Healthy Lower Backs' is most likely going to be cost effective for not only the UK National Health Service (NHS), but for the wider society as well. The specially-developed 12-week group yoga intervention program was observed and compared to conventional general practitioner (GP) care alone. In order to decide if this was an appropriate use of NHS resources, the cost of the program needed to be checked out...
