Chronic Pain Alters DNA Marking In The Brain
Date: Feb-18-2013Injuries that result in chronic pain, such as limb injuries, and those unrelated to the brain are associated with epigenetic changes in the brain which persist months after the injury, according to researchers at McGill University. Epigenetics explores how the environment - including diet, exposure to contaminants and social conditions such as poverty - can have a long-term impact on the activity of our genes. The team led by Prof. Laura Stone, a professor at the Faculty of Dentistry and the Alan Edwards Centre for Research on Pain, and Prof...
New Findings On Morning Sickness Treatment Presented At Society For Maternal-Fetal Medicine Annual Pregnancy Meeting
Date: Feb-18-2013Early use of Diclectin(R) reduces the severity of nausea and vomiting of pregnancy (NVP) symptoms in pregnant women who had severe NVP in a previous pregnancy Duchesnay Inc. announced results from a new study concluding that pre-emptive use of Diclectin(R) (a delayed-release combination of 10 mg doxylamine and 10 mg pyridoxine) is effective in reducing symptoms of severe NVP in patients at high risk for recurrence of severe NVP. The study was conducted by Gideon Koren, M.D., and Caroline Maltepe, B.A...
Common Chemicals Linked To Osteoarthritis
Date: Feb-18-2013A new study has linked exposure to two common perfluorinated chemicals (PFCs) with osteoarthritis. PFCs are used in more than 200 industrial processes and consumer products including certain stain- and water-resistant fabrics, grease-proof paper food containers, personal care products, and other items. Because of their persistence, PFCs have become ubiquitous contaminants of humans and wildlife...
The Effectiveness Of Community-Based, Substance Abuse Prevention Interventions Begun During Middle School Years
Date: Feb-18-2013Middle school students from small towns and rural communities who received any of three community-based prevention programs were less likely to abuse prescription medications in late adolescence and young adulthood. The research, published in the American Journal of Public Health, was funded by the National Institute on Drug Abuse (NIDA), the National Institute on Alcohol Abuse and Alcoholism, and the National Institute of Mental Health, all components of the National Institutes of Health...
Smart Surveillance Rapidly Identifies Emerging Disease Threats
Date: Feb-18-2013EcoHealth Alliance, the nonprofit organization that focuses on local conservation and global health issues, announced new research focused on the rapid identification of disease outbreaks in the peer reviewed publication, Journal of the Royal Society Interface. The article, authored by leading scientists in the fields of emerging disease ecology, biomathematics, computational biology and bioinformatics, shows how network theory can be used to identify outbreaks of unidentified diseases...
Probiotic Helps Male Mice Build Healthy Bones
Date: Feb-18-2013In what could be an early step toward new treatments for people with osteoporosis, scientists at Michigan State University report that a natural probiotic supplement can help male mice produce healthier bones. Interestingly, the same can't be said for female mice, the researchers report in the Journal of Cellular Physiology. "We know that inflammation in the gut can cause bone loss, though it's unclear exactly why," said lead author Laura McCabe, a professor in MSU's departments of Physiology and Radiology. "The neat thing we found is that a probiotic can enhance bone density...
The Genetic Transmission Of Traits Reflects Alterations In Genetic Structure: Life Experiences Put Their Stamp On The Next Generation
Date: Feb-18-2013The 18th century natural philosopher Jean-Baptiste Lamarck proposed that the necks of giraffes lengthened as a consequence of the cumulative effort, across generations, to reach leaves just out of their grasp. This view of evolution was largely abandoned with the advent of modern genetic theories to explain the transmission of most important traits and many medical illnesses across generations...
Published Work On Respiratory Syncytial Virus In Children From Le Bonheur Children's Hospital
Date: Feb-18-2013Studies at Le Bonheur are advancing our understanding of how viruses, including RSV, replicate in humans, mutate to avoid the immune response and can be effectively treated. John DeVincenzo, MD, medical director of Molecular Diagnostics and Virology Laboratories at Le Bonheur, and professor of Pediatrics and Microbiology, Immunology, and Molecular Biology at The University of Tennessee Health Science Center, has recently published three papers on this topic. DeVincenzo's lab is one of only two of its kind in the United States...
New Medical Tool Could Help Surgeons Carrying Out Complex Procedures In The Operating Theatre
Date: Feb-18-2013Researchers have developed a dye which provides a quick and accurate method of checking heparin levels in the blood. Heparin is an important anti-coagulant which has a significant role in major surgery. The scientists in the Department of Chemistry at York have used inspiration from biological systems to allow the dye to bind heparin even in highly competitive human serum. In the laboratory, they have modified existing dyes which previously could not bind with heparin successfully under these challenging conditions...
Cell Adhesion Abnormalities Implicated In Cardiovascular Disease And Cancer
Date: Feb-18-2013Research carried out by scientists at the Georgia Institute of Technology and The University of Manchester has revealed new insights into how cells stick to each other and to other bodily structures, an essential function in the formation of tissue structures and organs. It's thought that abnormalities in their ability to do so play an important role in a broad range of disorders, including cardiovascular disease and cancer...
