Identifying Pathways In The Brain To Understand The Underlying Molecular Mechanism Of Huntington's Disease
Florida Atlantic University researcher Dr. Jianning Wei, assistant professor of biomedical sciences in the Charles E. Schmidt College of Biomedical Science at FAU, has received a grant from the National Institutes of Health (NIH) to further her research into the molecular mechanisms of Huntington"s disease (HD). Named after American physician George Huntington, HD is a highly complex genetic, neurological disorder that causes certain nerve cells in the brain to waste away. The disease, characterized by a selective loss of neurons in the brain, affects the basal ganglia, which controls motor control, cognition, learning and emotions. It also affects the outer surface of the brain, or the cortex which controls thought, perception, and memory. Wei and her colleagues are working to identify the pathways in the brain that are altered in response to mutant proteins, as well as to understand the cellular processes impacted by the disease in order to facilitate the development of effective pharmacological interventions.

Four Out Of 106 Heart Replacement Valves From Pig Hearts Failed
Pig heart valves used to replace defective aortic valves in human patients failed much earlier and more often than expected, says a report from cardiac surgeons at Washington University School of Medicine in St. Louis. This is the first report to demonstrate this potential problem, the researchers say.

Study Supports Validity Of Test That Indicates Widespread Unconscious Bias
In the decade since the Implicit Association Test was introduced, its most surprising and controversial finding is its indication that about 70 percent of those who took a version of the test that measures racial attitudes have an unconscious, or implicit, preference for white people compared to blacks. This contrasts with figures generally under 20 percent for self report, or survey, measures of race bias.

Eat Right, Stay Bright This Winter

"Beware the winter" warn dietitians as research shows more Australians turn to comfort foods at this time of year. According to Australia"s peak nutrition body, the Dietitians Association of Australia (DAA), more Australians eat pastries, cakes and chocolates, and less eat fruit, during the colder months1. Australia"s last national nutrition survey found more than 70 per cent of Australian adults indulge in less nutritious "cereal-based" foods during the winter months1. Such foods included pizza, cakes, pastries, battered food, commercial hamburgers and biscuits. But dietitians say choosing the right "comfort" foods during winter can help you stay healthy and happy all year round. DAA Spokesperson Lisa Renn said: "On short, cool days, it"s tempting to reach for fatty and sugary comfort foods. But any boost from these foods is usually short lived, so you end up with less energy - and more weight in the long term". Ms Renn, an Accredited Practising Dietitian, said the right comfort foods are lower in sugar, fat and kilojoules (energy). "Try nourishing foods like porridge with reduced-fat milk and fruit, chunky vegetable and lentil soups, and slow-cooked casseroles made with lean meat and vegetables like potato and carrot," said Ms Renn. She also recommends eating healthy, low glycaemic index (GI) foods for sustained energy, and maintaining regular physical activity to boost energy levels. Try these tips from the DAA to stay energised this winter: - Cook healthy soups and casseroles in bulk and freeze in meal-sized containers for a quick meal. - Piping hot drinks can be a great way to stay warm. Use reduced-fat milk and limit added sugar. - Keep up a regular exercise routine over winter. Rug up when heading outdoors and have bad weather options to fall back on, such as an exercise DVD. - Warm up with a chunky vegetable soup and crusty wholegrain bread roll. - Try a baked apple with reduced-fat custard for a healthy dessert. - Curries or hearty casseroles make a tasty meal on cold winter nights. Choose lean cuts of meat and experiment with different vegetables. - Baked potatoes are a great winter idea. Try topping potatoes with sliced mushrooms, reduced-fat cheese and chives. 1National Nutrition Survey, 1995 ABS catalogue number 4805.0.
