Baylor University researchers study barriers, resources to physical activity in Texas towns

WACO, Texas (Feb. 20, 2013) —Obesity, diabetes and other ailments plague impoverished communities at higher rates than the general United States population. In rural Texas border towns, or colonias, Mexican-American residents are at an even greater risk for chronic health problems.

Activation of cortical type 2 cannabinoid receptors ameliorates ischemic brain injury

Philadelphia, PA, February 21, 2013 – A new study published in the March issue of The American Journal of Pathology suggests that cortical type 2 cannabinoid (CB2) receptors might serve as potential therapeutic targets for cerebral ischemia.

The brainless origin of our head

In many animals, the brain is located in a specific structure, the head, together with sensory organs and often together with the mouth. However, there are even more distantly related animals, which have a nervous system, but no brain, like sea anemones and corals.

Wanted: A life outside the workplace

EAST LANSING, Mich. — A memo to employers: Just because your workers live alone doesn't mean they don't have lives beyond the office.

New research at Michigan State University suggests the growing number of workers who are single and without children have trouble finding the time or energy to participate in non-work interests, just like those with spouses and kids.

Workers struggling with work-life balance reported less satisfaction with their lives and jobs and more signs of anxiety and depression.

Rutgers neuroscientist sheds light on cause for 'chemo brain'

It's not unusual for cancer patients being treated with chemotherapy to complain about not being able to think clearly, connect thoughts or concentrate on daily tasks. The complaint – often referred to as chemo-brain – is common. The scientific cause, however, has been difficult to pinpoint.

In rich and poor nations, giving makes people feel better than getting, research finds

WASHINGTON - Feeling good about spending money on someone else rather than for personal benefit may be a universal response among people in both impoverished countries and rich nations, according to new research published by the American Psychological Association.

"Our findings suggest that the psychological reward experienced from helping others may be deeply ingrained in human nature, emerging in diverse cultural and economic contexts," said lead author Lara Aknin, PhD, of Simon Fraser University in Canada.

Schizophrenia genes increase chance of IQ loss

People who are at greater genetic risk of schizophrenia are more likely to see a fall in IQ as they age, even if they do not develop the condition.

Scientists at the University ofEdinburgh say the findings could lead to new research into how different genes for schizophrenia affect brain function over time. They also show that genes associated with schizophrenia influence people in other important ways besides causing the illness itself.

The researchers used the latest genetic analysis techniques to reach their conclusion on how thinking skills change with age.

UCLA life scientists identify drug that could aid treatment of anxiety disorders

The drug scopolamine has been used to treat a variety of conditions, including nausea and motion sickness. A new study by UCLA life scientists suggests that it may also be useful in treating anxiety disorders.

Cooling may prevent trauma-induced epilepsy

In the weeks, months and years after a severe head injury, patients often experience epileptic seizures that are difficult to control. A new study in rats suggests that gently cooling the brain after injury may prevent these seizures.

Scientists identify molecular system that could help develop treatments for Alzheimer's disease

Scientists from the University of Southampton have identified the molecular system that contributes to the harmful inflammatory reaction in the brain during neurodegenerative diseases.

An important aspect of chronic neurodegenerative diseases, such as Alzheimer's, Parkinson's, Huntington's or prion disease, is the generation of an innate inflammatory reaction within the brain.

Study advances LSUHSC research, shows fish oil component reduces brain damage in newborns

New Orleans, LA – Research 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.

Omega-3 lipid emulsions markedly protect brain after stroke in mouse study

New York, NY (February 20, 2013) — Triglyceride lipid emulsions rich in an omega-3 fatty acid injected within a few hours of an ischemic stroke can decrease the amount of damaged brain tissue by 50 percent or more in mice, reports a new study by researchers at Columbia University Medical Center.

The results suggest that the emulsions may be able to reduce some of the long-term neurological and behavioral problems seen in human survivors of neonatal stroke and possibly of adult stroke, as well. The findings were published today in the journal PLoS One.

Antioxidants in your diet may not reduce risk of stroke or dementia

MINNEAPOLIS – Contrary to other research, a new study found that the total level of antioxidants in people's diets is not related to their risk of developing stroke or dementia. The study is published in the February 20, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. Antioxidants such as lycopene, beta-carotene and vitamins C and E are found in many foods.

Bullied children can suffer lasting psychological harm as adults

DURHAM, NC – Bullied children grow into adults who are at increased risk of developing anxiety disorders, depression and suicidal thoughts, according to a study led by researchers at Duke Medicine.

The findings, based on more than 20 years of data from a large group of participants initially enrolled as adolescents, are the most definitive to date in establishing the long-term psychological effects of bullying.

Employees shed pounds in worksite-based weight loss intervention with behavioral counseling

BOSTON (Wednesday, February 20, 2013)- Workplace-based programs that include dietary advice coupled with behavioral counseling appear to be a promising approach for men and women with significant weight loss goals, based on the results of a pilot study conducted by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University. Employees enrolled in the intervention arm of a randomized controlled trial lost on average, 18 pounds over a six-month period compared to a two pound weight gain in a control group.
