Public release date: 29-Jul-2013 [ | E-mail | Share ] Contact: Gina Bericchia Gina.Bericchia@NationwideChildrens.org 614-355-0495 Nationwide Children's Hospital Researchers who collect genetic samples from children for medical research need to explain the process more clearly to parents, according to a new study that suggests many parents don't fully understand the finer details about how these samples will be used and stored. The study was published in June in Genetics in Medicine. Kim McBride, MD, MS, principal investigator in the Center for Cardiovascular and Pulmonary Research in The Research Institute at Nationwide Children's Hospital, and colleagues followed up with families enrolled in a genetic biobanka storage facility for DNA, genetic data, and tissue samplesafter their initial consent, to find out whether they were fully aware of the nature of their agreement. The results were alarming: more than half of all parents misunderstood key concepts of the study. Ensuring parental understanding of the consent process is a crucial element of ethical genetics research, says Dr. McBride. For the study, he and his colleagues collected anonymous questionnaires from families that had consented between 2004 and 2008 to the storage and analysis of their children's DNA samples in a genetic biobank. The biobank was … Continue reading →

Unstable genetic "capacitor" can "discharge" to accelerate the pace of evolutionary change. Scientists historically have argued that evolution proceeds through gradual development of traits. But how can incremental changes apply to the binary switch between two sexes, male or female? Researchers at Case Western Reserve University's School of Medicine have found that a genetic process among the many species of rodents could have significant implications regarding our assumptions about sex determination and the pace of evolution. "What we addressed is a long-standing puzzle in natural history: why different types of rodents can exhibit profound differences in how male sex is determined in the embryo," said Michael Weiss, MD, PhD, chairman of the Department of Biochemistry, the Cowan-Blum Professor of Cancer Research and a professor of biochemistry and medicine. "Some rodent populations have both XY males and XY females, and in other populations the Y chromosome has disappeared entirely." In a study published in Proceedings of the National Academy of Sciences, Weiss and his research team analyzed the Sry gene, which is part of the Y chromosome. This mammalian gene, which steers differentiation in the embryonic gonad toward the development of testes, begins the process leading to the birth of males. … Continue reading →

Washington, July 29 (ANI): Scientists have discovered that a faulty genetic pathway could be responsible for a range of allergies. The research by the Johns Hopkins Children's Center and the Johns Hopkins Institute of Genetic Medicine has found that aberrant signalling by a protein called transforming growth factor-beta, or TGF-beta, may be responsible for disrupting the way immune cells respond to common foods and environmental allergens, leading to a wide range of allergic disorders. It was found that mutations in the genes that lead to abnormal TGF-beta signaling are also keys to Marfan and Loeys-Dietz syndromes, genetic conditions marked by blood vessel laxity and dangerous stretching of the aorta, the body's largest blood vessel. "Disruption in TGF-beta signalling does not simply nudge immune cells to misbehave but appears to singlehandedly unlock the very chain reaction that eventually leads to allergic disease," senior investigator Harry "Hal" Dietz, M.D. said. The study involved 58 children with LDS, ages 7 to 20, followed at Johns Hopkins. Most of them had either a history of allergic disease or active allergies, like allergic rhinitis, eczema, food allergies, asthma, and gastrointestinal and esophageal allergic disease. These patients also had abnormally high levels of several traditional markers … Continue reading →

Featured Article Academic Journal Main Category: Stroke Also Included In: Neurology / Neuroscience;Stem Cell Research Article Date: 29 Jul 2013 - 0:00 PDT Current ratings for: Stem cell discovery: Astrocytes could repair stroke brain damage 4.5 (6 votes) Stem cell researchers have discovered that astrocytes may prove useful against stroke and other brain disorders. Astrocytes - neural cells that form the blood-brain barrier and so control what can and cannot enter the brain from the blood supply - have previously been overlooked in this area of stroke research. A collaborative study published in Nature Communications suggests that astrocytes can do far more than simply support nerve cells (neurons). Wenbin Deng, senior author of the study and associate professor of biochemistry and molecular medicine at UC Davis in California, told Medical News Today: "This exciting research uncovers the brain-protective powers of stem cell-derived astrocytes. Astrocytes may help to limit the spread of damage after an ischemic brain stroke in patients, and may also help to regenerate and repair damaged brain cells. Both of these actions may lead to better functional recovery in patients." Visit link: Stem cell discovery: Astrocytes could repair stroke brain damage … Continue reading →

A Vail doctor is in the midst of employing cutting edge medical technology that could bring an end to invasive reconstructive surgery for people with joint and cartilage injuries. Dr. Scott Brandt, M.D., medical director of ThriveMD in Edwards, has a background in anesthesiology and specializes in regenerative and restorative medicine. He is one of a handful of doctors in the country who recently began employing the natural regenerative benefits of stem cells as an alternative to highly invasive joint replacement surgeries for patients with acute and chronic pain in their knees, shoulders, wrists, ankles, hands, feet, hips, elbows and certain spinal conditions. In addition, because stem cells can take the form of bone, cartilage, ligament, tendons, muscle or fat, they also can be used to treat debilitating conditions, such as degenerative arthritis, rheumatoid arthritis or osteoarthritis. Trained at the University of Illinois and Michael Reese hospitals in Chicago, Brandt first began practicing in Denver. Although he moved to Vail eight years ago, he waited until last September to move his practice and open ThriveMD. Ive been specializing in bioidentical therapy in some form (since 1997), but I didnt think this procedure was quite ready for prime time until about … Continue reading →

Forget about cash-start banking your body. Using a technology that echoes science fiction movies, a French company is offering people a "bank" to store their own stem cells for years in a bet that those cells may be used to grow replacement organs and possibly save their lives someday. "It's a personal deposit of your cell," said Dr. Andr Choulika, CEO of the biotech company Cellectis, which is launching the stem-cell bank known as Scil this month. Given the rate of developments in stem-cell research and their potential for curbing health costs, Choulika thinks Scil's model of creating and storing stem cells one day will become so cheap that it will become mandatory for people with medical insurance. "This pace of science currently goes so fast, probably in a few years, less than 10 years, everyone will have their own cell backup, and it will be a requirement," said Choulika, whose company is named after the Gaelic word for "story," and is pronounced "sail" by Choulika. "We believe that regenerative medicine is the future," he said. In the present, though, it is anything but cheap. Scil's services cost $60,000, Choulika said, adding that it is "a one-time payment, for your … Continue reading →
