Study holds hope of a treatment  for deadly genetic disease, MPS IIIB

LOS ANGELES – (Sept. 29, 2014) –MPS IIIB is a devastating and currently untreatable disease that causes progressive damage to the brain, leading to profound intellectual disability, dementia and death -- often before reaching adulthood.

New learning mechanism for individual nerve cells

The traditional view is that learning is based on the strengthening or weakening of the contacts between the nerve cells in the brain. However, this has been challenged by new research findings from Lund University in Sweden. These indicate that there is also a third mechanism – a kind of clock function that gives individual nerve cells the ability to time their reactions.

Modeling shockwaves through the brain

Since the start of the military conflicts in Iraq and Afghanistan, more than 300,000 soldiers have returned to the United States with traumatic brain injury caused by exposure to bomb blasts — and in particular, exposure to improvised explosive devices, or IEDs. Symptoms of traumatic brain injury can range from the mild, such as lingering headaches and nausea, to more severe impairments in memory and cognition.

Self-compassion key to positive body image and coping

Women who accept and tolerate their imperfections appear to have a more positive body image despite their body mass index (BMI) and are better able to handle personal disappointments and setbacks in their daily lives.

Research out of the Faculty of Arts at the University of Waterloo found that this self-compassion might be an important means to increase positive body image and protect girls and young women against unhealthy weight-control practices and eating disorders.

Chefs move to schools can increase school meal participation and vegetable intake among students

Gourmet pizza in school? According to a new Food and Brand Lab pilot study, published in Appetite, chef-made meals can increase participation in the National School Lunch Program (NSLP) by 9% and overall selection and consumption of vegetables by 16%!

Chefs Move to Schools (CMTS), an initiative of Michelle Obama's Let's Move campaign, pairs chefs with schools in order to provide nutrition instruction to students and culinary advice to interested school food service workers.

Transplant drug could boost the power of brain tumor treatments, U-M study finds

ANN ARBOR, Mich. — Every day, organ transplant patients around the world take a drug called rapamycin to keep their immune systems from rejecting their new kidneys and hearts. New research suggests that the same drug could help brain tumor patients by boosting the effect of new immune-based therapies.

In experiments in animals, researchers from the University of Michigan Medical School showed that adding rapamycin to an immunotherapy approach strengthened the immune response against brain tumor cells.

A 'frenemy' in Parkinson's disease takes to crowdsourcing

The protein alpha-synuclein is a well-known player in Parkinson's disease and other related neurological conditions, such as dementia with Lewy bodies. Its normal functions, however, have long remained unknown. An enticing mystery, say researchers, who contend that understanding the normal is critical in resolving the abnormal.

BUSM researchers identify brain changes involved in alcohol-related sleep disturbances

(Boston) – A review article published online in Behavioral Brain Research provides novel insight into changes that happen in the brain as a result of chronic alcohol exposure that can lead to disruptions in the sleep cycle.

Clinical assessments and research indicate that individuals with alcohol use disorders frequently suffer from severely disrupted sleep. This can occur when people are actively drinking, when they are going through withdrawal or when they are abstaining.

Study reveals new clues to help understand brain stimulation

BOSTON – Over the past several decades, brain stimulation has become an increasingly important treatment option for a number of psychiatric and neurological conditions.
