Alzheimer's Disease: Green Tea Extract Found To Interfere With The Formation Of Amyloid Plaques
Date: Mar-08-2013Researchers at the University of Michigan have found a new potential benefit of a molecule in green tea: preventing the misfolding of specific proteins in the brain. The aggregation of these proteins, called metal-associated amyloids, is associated with Alzheimer's disease and other neurodegenerative conditions...
Progression Of Barrett's Esophagus To Esophageal Adenocarcinoma May Be Predicted By Biomarkers
Date: Mar-08-2013A series of microRNA expression signatures that may help to define progression of the precancerous condition Barrett's esophagus into esophageal adenocarcinoma was reported recently in Cancer Prevention Research, a journal of the American Association for Cancer Research...
Stress-Based Drug Relapse Halted In Rats
Date: Mar-08-2013In a new study in Neuron, scientists identified specific key steps in the chain of events that causes stress-related drug relapse. They identified the exact region of the brain where the events take place in rat models and showed that by blocking a step, they could prevent stress-related relapse. All too often, stress turns addiction recovery into relapse, but years of basic brain research have provided scientists with insight that might allow them develop a medicine to help...
'Prevent Loss' Message Better Than 'Provide Benefits' In Blood Donation Campaigns
Date: Mar-08-2013Subtle changes in messaging can have a profound impact on the effectiveness of charitable messages such as calls for blood donations, according to research published in the open access journal PLOS ONE by Eileen Chou from the University of Virginia and co-author Keith Murnighan at Northwestern University. Though chronic shortages in U.S blood banks could be alleviated by a small increase in the number of blood donors, people are not always motivated enough to help...
Brain Injury May Be Autoimmune Phenomenon, Like Multiple Sclerosis
Date: Mar-08-2013Most scientists are starting to agree that repeat, sub-concussive hits to the head are dangerous and linked to neurological disorders later in life. A new collaborative study, though, attempted to find out why - and discovered that damage to the blood-brain barrier and the resulting autoimmune response might be the culprit...
Focusing On One Speaker In A Noisy Crowd To Solve The 'Cocktail Party Problem'
Date: Mar-08-2013In the din of a crowded room, paying attention to just one speaker's voice can be challenging. Research in the Cell Press journal Neuron demonstrates how the brain hones in on one speaker to solve this "Cocktail Party Problem." Researchers discovered that brain waves are shaped so that the brain can selectively track the sound patterns from the speaker of interest and at the same time exclude competing sounds from other speakers...
A Role Played By A Portion Of The Hippocampus In Modulating Anxiety
Date: Mar-08-2013Columbia University Medical Center (CUMC) researchers have found the first evidence that selective activation of the dentate gyrus, a portion of the hippocampus, can reduce anxiety without affecting learning. The findings suggest that therapies that target this brain region could be used to treat certain anxiety disorders, such as panic disorder and post-traumatic stress syndrome (PTSD), with minimal cognitive side effects. The study, conducted in mice, was published in the online edition of the journal Neuron. The dentate gyrus is known to play a key role in learning...
Improving Healthy Beverage Practices In Child Care, Increasing Consumption Of Water
Date: Mar-08-2013Support is needed in child care centers to help meet existing water policies and new water requirements included in the 2010 Child Nutrition Reauthorization Act, according to a study published by the Yale Rudd Center for Food Policy & Obesity. The study, published in the March/April 2013 issue of the Journal of Nutrition Education and Behavior, is the first to document availability and accessibility of water in compliance with state and federal policy and accreditation standards in child care centers...
Cash Can Coax Dieters To Lose Weight
Date: Mar-08-2013When motivating people to lose weight, money is an effective incentive, a new study by the Mayo Clinic reveals. Participants in a weight loss study who received financial incentives were noticeably more likely to adhere to a weight-loss program and collectively lost more weight than those who did not get incentives. Earlier research has shown that financial rewards encourage people to lose weight, however, the current study analyzed a much larger group of participants (100) over a longer period (one year), according to author Steven Driver, M.D...
Children Benefit From School-Based Kitchen Gardens
Date: Mar-08-2013Grow it, try it, and you just might like it is a motto many schools are embracing to encourage children to eat more fruits and vegetables. Through community-based kitchen garden programs, particularly those with dedicated cooking components, schools are successfully introducing students to healthier foods. In a new study released in the March/April 2013 issue of the Journal of Nutrition Education and Behavior, researchers found that growing and then cooking the foods that kids grew increased their willingness to try new foods...
