Bioethicists Call For Collaborative Consent To Ensure Ethical Practices While Leveraging The Web's Research Potential
Date: Feb-22-2013Status updates, patient forums, blog comments - among the incredible amount of personal information on the Web is a potential trove of health data. Bioethicists writing in Science Translational Medicine acknowledge the value of this resource but argue that to be ethically acceptable for use in research, traditional models of informed consent must be adapted to suit the dynamic online environment...
Researchers Implant Ultrathin Nanowires To Receive First Signals From Brain Nerve Cells
Date: Feb-22-2013Electrodes inserted into the brain are today used in research and to treat diseases such as Parkinson's. However, their use has been limited by their size. At Lund University in Sweden, researchers have, for the first time, succeeded in implanting an ultrathin nanowire-based electrode and capturing signals from the nerve cells in the brain of a laboratory animal. The researchers work at Lund University's Neuronano Research Centre in an interdisciplinary collaboration between experts in subjects including neurophysiology, biomaterials, electrical measurements and nanotechnology...
Chemical Reaction With Methylene Blue, Potential Alzheimer's Drug, Modifies Tau Proteins
Date: Feb-22-2013The chemical compound known as "methylene blue" is a potential candidate for treating Alzheimer's, as it prevents the harmful clumping of so-called tau proteins typically associated with this disease. However, until now it was unknown why methylene blue had this effect. Researchers from Göttingen and Bonn have now shed light on this microscopic process. The study published in Angewandte Chemie might help to work out strategies for developing potential drugs...
Sport And Business Performance May Be Improved By Healthy Rivalry
Date: Feb-22-2013New research shows that people can recover from poor performance when rivals comment on their failures. The research, to be published in the Journal of Experimental Social Psychology, shows that while criticism from team members sends individuals into downward performance spirals, external criticism can be a trigger that boosts performance as people try to prove the outsiders wrong...
Fish Oil Component Reduces Brain Damage In Newborns
Date: Feb-22-2013Research conducted by a team of scientists from Columbia University College of Physicians and Surgeons and Dr. Nicolas Bazan, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health Sciences Center New Orleans, found the novel use of a component of fish oil reduced brain trauma in newborn mice. The study reports that neonatal brain damage decreased by about 50% when a triglyceride lipid emulsion containing docosahexaenoic acid (DHA) was injected within two hours of the onset of ischemic stroke...
Quality Of Patient Care In Hospitals May Be Affected By Staff Satisfaction
Date: Feb-22-2013The satisfaction levels among a hospital's staff are closely linked to the quality of healthcare it provides, say a team of doctors from Imperial College London. In the first study of its kind, Dr Richard Pinder and colleagues at Imperial found that hospitals in England with lower mortality rates were more likely to have members of staff satisfied with the quality of care they provide. Despite the researchers' initial assumptions, satisfaction levels among non-clinical staff were found to be as closely tied to a hospital's performance as those of doctors...
How Surprisingly Potent Hepatitis C Drug Works Revealed By Computer Modeling
Date: Feb-22-2013A study by researchers from Los Alamos National Laboratory and a multinational team reveals how daclatasvir, a direct-acting antiviral agent in development for the treatment of hepatitis C virus (HCV), targets one of its proteins and causes the fastest viral decline ever seen with anti-HCV drugs - within 12 hours of treatment. Chronic infection with hepatitis C virus affects about 150 million people worldwide. It is the leading cause of cirrhosis, liver cancer and liver transplants and results in some 350,000 deaths worldwide every year...
Possible Link Between Childhood Obesity And ADHD, Learning Disabilities
Date: Feb-22-2013A University of Illinois study has established a possible link between high-fat diets and such childhood brain-based conditions as attention deficit hyperactivity disorder (ADHD) and memory-dependent learning disabilities. "We found that a high-fat diet rapidly affected dopamine metabolism in the brains of juvenile mice, triggering anxious behaviors and learning deficiencies...
Children With Heart Defects May Experience Abnormal Growth Regulation
Date: Feb-22-2013The poor growth seen in children born with complex heart defects may result from factors beyond deficient nutrition. A new study by pediatric researchers suggests that abnormalities in overall growth regulation play a role. "When compared with their healthy peers, children with congenital heart disease have impaired growth, as measured in weight, length, and head circumference," said senior author Meryl S. Cohen, M.D., a pediatric cardiologist in the Cardiac Center at The Children's Hospital of Philadelphia...
Delirium Can Lead To Short- And Long-Term Confusion And Memory Problems But Simple Measures To Promote Sleep Can Help In Intensive Care
Date: Feb-22-2013A hospital is not the best place to get a good night's sleep, especially in a noisy intensive care unit. It's a cause for concern because studies have shown that a lack of sleep can cause patients to experience delirium - an altered mental state that may delay their recovery and lead to short and long-term confusion and memory problems...
