Veterans with blast-induced traumatic brain injury report poorer vision quality
Date: Oct-18-2013Veterans with blast-induced traumatic brain injury (TBI) reported poorer vision quality on questionnaires, according to a report by Sonne Lemke, Ph.D., of the VA Palo Alto Health Care System, Menlo Park, Calif., and colleagues. TBI is an important health issue. More than 280,000 cases of TBI have been identified in U.S. military members since 2000, the authors write in the study background. Researchers administered questionnaires to 60 veterans with TBI to assess the effect of blast exposure on perceived visual functioning...
Scientists hope new soy flour will reduce dementia risk
Date: Oct-18-2013Scientists in Loughborough and Indonesia have developed a new soy-based flour product they hope will improve memory in older age and reduce the risk of dementia. The flour originates from tempe - a fermented soy-based product similar to tofu used widely in Asian cooking. Tempe contains phytoestrogens (plant based hormones) and several B vitamins and has been shown in studies to be associated with improved memory function amongst the older population...
New international practical reference guide: which probiotics for which lower GI symptoms?
Date: Oct-18-2013Doctors, people with gastrointestinal (GI) problems as well as the general public are becoming increasingly aware of the probiotics in general. However, with the increasingly broad range of products, it is difficult to choose which probiotics might be useful for a specific GI problem. For a number of lower GI symptoms in adults, an international guide now identifies, based on sound scientific evidence, which available probiotics are helpful. The guide will also be presented today at the United European Gastroenterology Week (UEG Week) in Berlin...
Autistic children look less friendly to peers
Date: Oct-18-2013A new study suggests that children with autism are seen as less friendly and less trustworthy by their peers, based solely on their appearance. The research, published in the journal Autism, suggests that typically developing children are less positive towards children with autism and form negative impressions after just a 30-second encounter. Dr Steven Stagg of Anglia Ruskin University, and psychologists at Royal Holloway, University of London, investigated the initial impressions that typically developing children form when watching silent videos of children with autism...
Babies know when you're faking
Date: Oct-18-2013If you're happy and you know it, clap your hands! That's easy enough for children to figure out because the emotion matches the movement. But when feelings and reactions don't align, can kids tell there's something wrong? New research from Concordia University proves that they can - as early as 18 months. In a study recently published in Infancy: The Official Journal of the International Society on Infant Studies, psychology researchers Sabrina Chiarella and Diane Poulin-Dubois demonstrate that infants can detect whether a person's emotions are justifiable given a particular context...
Sleep is 'detox' for the brain
Date: Oct-18-2013New research shows that a recently discovered mechanism that removes waste products from the brain is mainly active during sleep. This revelation could transform scientific understanding of what sleep is for, and how it works and offers new directions for brain disease treatments. The team, from University of Rochester Medical Center (URMC), write about their findings in the latest online issue of Science. Lead author Dr...
Developing world faces breast cancer surge, study suggests
Date: Oct-18-2013Rising breast cancer incidence and mortality represent a significant and growing threat for the developing world, according to a new global study commissioned by GE Healthcare. Explained report co-author Bengt Jönsson, Professor in Health Economics at the Stockholm School of Economics: "Breast cancer is on the rise across developing nations, mainly due to the increase in life expectancy and lifestyle changes such as women having fewer children, as well as hormonal intervention such as post-menopausal hormonal therapy...
Drugs for hypertension shown to decrease risk of Alzheimer's disease dementia
Date: Oct-18-2013A Johns Hopkins-led analysis of data previously gathered on more than 3,000 elderly Americans strongly suggests that taking certain blood pressure medications to control blood pressure may reduce the risk of dementia due to Alzheimer's disease (AD). In a report published in a recent edition of the journal Neurology, a team of researchers found that people over the age of 75 with normal cognition who used diuretics, angiotensin-1 receptor blockers (ARBs) and angiotensin-converting enzyme (ACE) inhibitors showed a reduced risk of AD dementia by at least 50 percent...
Scientists attempting to predict health risks posed by everyday chemicals
Date: Oct-18-2013Concern over the safety of everyday household products, such as baby bottles and soaps, has spurred a wide-ranging research effort into predicting the health risks of tens of thousands of chemicals. That's the topic of the cover story in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society. Britt E. Erickson, C&EN senior editor, points out that the U.S. Environmental Protection Agency (EPA) is charged with overseeing the safety of chemicals in consumer products...
Light pulses stimulate designer peptides to initiate a death pathway in cancerous cells
Date: Oct-18-2013Researchers at Cardiff University have created a peptide (a small piece of protein), linked to a light-responsive dye, capable of switching 'on' death pathways in cancer cells. The peptide remains inactive until exposed to external light pulses which convert it into a cell death signal. Complex mechanisms in healthy cells normally protect us from developing cancer. However, when the finely balanced networks of interactions between proteins that control such mechanisms are disturbed, uncontrolled cell growth can occur...
