Return to play after concussion: Consensus reports summarized
Date: Aug-28-2013Concussions are a common sports injury that can have long-term neurological consequences if not properly diagnosed and treated. Several new or updated guidelines for managing sports concussions were released earlier this year, and their key areas of consensus, including recommendations for return to play, are presented in an article in Journal of Neurotrauma, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Journal of Neurotrauma website. Therese A. West, DNP and Donald W...
Intracerebral stem cell injections to prevent/reduce post-stroke cognitive deficits
Date: Aug-28-2013Cognitive deficits following ischemic stroke are common and debilitating, even in the relatively few patients who are treated expeditiously so that clots are removed or dissolved rapidly and cerebral blood flow restored. A new study in Restorative Neurology and Neuroscience demonstrates that intracerebral injection of bone-marrow-derived mesenchymal stem cells (BSCs) reduces cognitive deficits produced by temporary occlusion of cerebral blood vessels in a rat model of stroke, suggesting that BSCs may offer a new approach for reducing post-stroke cognitive dysfunction...
Flame retardant HBCD worldwide ban
Date: Aug-28-2013The flame retardant HBCD may no longer be produced or used. This was decided by representatives from over 160 countries in late May at a UN conference on chemicals in Geneva. Empa's extensive research on HBCD, formerly used as a flame retardant for plastics, electronics and textiles, and especially for insulation panels in buildings, contributed to the new regulation of HBCD under the Stockholm Convention on Persistent Organic Pollutants (POPs). It is a lengthy process before a contaminant is identified as such and its harmful effects are highlighted with a worldwide ban...
The brain's internal image of the body shaped by touch and movement neurons
Date: Aug-28-2013The brain's tactile and motor neurons, which perceive touch and control movement, may also respond to visual cues, according to researchers at Duke Medicine. The study in monkeys, which appears online in the journal Proceedings of the National Academy of Sciences, provides new information on how different areas of the brain may work together in continuously shaping the brain's internal image of the body, also known as the body schema...
Potential therapeutic target suggested by finding that immune system, skin microbiome 'complement' one another
Date: Aug-28-2013Researchers from the Perelman School of Medicine at the University of Pennsylvania demonstrate for the first time that the immune system influences the skin microbiome. A new study found that the skin microbiome - a collection of microorganisms inhabiting the human body - is governed, at least in part, by an ancient branch of the immune system called complement. In turn, it appears microbes on the skin tweak the complement system, as well as immune surveillance of the skin...
Tumor growth reduced, cancer cells crippled by disabling ether lipid generating enzyme
Date: Aug-28-2013Knocking out a single enzyme dramatically cripples the ability of aggressive cancer cells to spread and grow tumors, offering a promising new target in the development of cancer treatments, according to a new study by researchers at the University of California, Berkeley. The paper, published in the journal Proceedings of the National Academy of Sciences, sheds new light on the importance of lipids, a group of molecules that includes fatty acids and cholesterol, in the development of cancer. Researchers have long known that cancer cells metabolize lipids differently than normal cells...
No contact with heart needed with new implanted defibrillator
Date: Aug-28-2013A new type of defibrillator implanted under the skin can detect dangerously abnormal heart rhythms and deliver shocks to restore a normal heartbeat without wires touching the heart, according to research in the American Heart Association journal, Circulation. The subcutaneous implantable cardiac defibrillator (S-ICD®) includes a lead placed under the skin along the left side of the breast bone. Traditional implantable cardiac defibrillators (ICDs) include electrical conducting wires inserted into blood vessels that touch the heart...
New minimally invasive technique for treating melanoma
Date: Aug-28-2013At first, Krista Easom figured the little red bump on her foot was nothing more than a blister. It didn't hurt, but after a couple months, it didn't go away either. She booked an appointment with a dermatologist to have it removed. She wasn't worried. Easom, a 24-year-old law school student from New Jersey, was healthy, had no family history of cancer and was getting ready to enjoy some time in her newly adopted city of Chicago. That's when she received the results from her dermatologist, who removed a part of the blister and had it tested...
Newly identified personality trait holds clues to why haters have to hate
Date: Aug-28-2013New research has uncovered the reason why some people seem to dislike everything while others seem to like everything. Apparently, it's all part of our individual personality - a dimension that researchers have coined "dispositional attitude." People with a positive dispositional attitude have a strong tendency to like things, whereas people with a negative dispositional attitude have a strong tendency to dislike things, according to research published in the Journal of Personality and Social Psychology...
Skin and food allergies can be result of skin cell 'glue' defeciency
Date: Aug-28-2013In a new study published in Nature Genetics, Northwestern Medicine and Tel Aviv University scientists have found that a structural defect in skin cells can contribute to allergy development, including skin and food allergies, traditionally thought primarily to be a dysfunction of the immune system. The finding is related to the team's identification of a new rare genetic disease, called "severe dermatitis, multiple allergies, and metabolic wasting," or SAM, caused by mutations in the molecule desmoglein 1...
