PHILADELPHIA - New Penn Medicine research has found that elevated levels in the blood of the brain-enriched protein calpain-cleaved αII-spectrin N-terminal fragment, known as SNTF, shortly after sports-related concussion can predict the severity of post-concussion symptoms in professional athletes. The complete findings were released today in the Journal of Neurotrauma.

TORONTO, Nov. 29, 2014--A chemical produced in the pancreas that prevented and even reversed Type 1 diabetes in mice had the same effect on human beta cells transplanted into mice, new research has found.

GABA, or gamma-aminobutryic acid, is an amino acid produced by the same beta cells that make and secrete insulin.

Learning-related brain activity in Parkinson's patients improves as much in response to a placebo treatment as to real medication, according to a new study by researchers at the University of Colorado Boulder and Columbia University.

MAYWOOD, Il. - An award-winning study by a Loyola University Chicago Stritch School of Medicine researcher has documented how homeless, mentally ill women in India face a vicious cycle:

During psychotic episodes, they wander away from home, sometimes for long distances, and wind up in homeless shelters. They then are returned to their families before undergoing sufficient psychosocial rehabilitation to deal with their illness. Consequently, they suffer mental illness relapses and wind up homeless again.

A higher surge of testosterone in competition, the so-called "winner effect," is not actually related to winning, suggests a new study of intercollegiate cross country runners.

The International Journal of Exercise Science published the research, led by David Edwards, a professor of psychology at Emory University, and his graduate student Kathleen Casto.

Researchers at the University of Leeds have shed light on a gene mutation linked to autistic traits.

The team already knew that some people with autism were deficient in a gene called neurexin-II. To investigate whether the gene was associated with autism symptoms, the Leeds team studied mice with the same defect.

They found behavioural features that were similar to autism symptoms, including a lack of sociability or interest in other mice.

Australian average incomes are falling with the country's population growth "masking underlying economic weakness", according to a QUT economist.

Dr Mark McGovern, a senior lecturer in QUT's Business School, said while it was regularly proclaimed Australia had experienced positive economic growth for more than 20 years, there had been periodic per capita declines, indicating the economy was not as healthy as assumed.

CHICAGO - In a study of nearly 2,000 adults, researchers found that a buildup of plaque in the body's major arteries was associated with mild cognitive impairment. Results of the study conducted at the University of Texas (UT) Southwestern Medical Center will be presented next week at the annual meeting of the Radiological Society of North America (RSNA).

UCLA neurophysicists have found that space-mapping neurons in the brain react differently to virtual reality than they do to real-world environments. Their findings could be significant for people who use virtual reality for gaming, military, commercial, scientific or other purposes.

Parents who spend their time playing with and talking to their five-month-old baby may wonder whether their child remembers any of it a day later.

Thanks to a new BYU study, we now know that they at least remember the good times.

The study, published in Infant Behavior and Development, shows that babies are more likely to remember something if there is a positive emotion, or affect, that accompanies it.

LA JOLLA, CA--November 24, 2014--A team led by scientists from The Scripps Research Institute (TSRI) has found a simple method to convert human skin cells into the specialized neurons that detect pain, itch, touch and other bodily sensations. These neurons are also affected by spinal cord injury and involved in Friedreich's ataxia, a devastating and currently incurable neurodegenerative disease that largely strikes children.

Good communication between brain cells is vital for optimal (mental) health. Mutations in the TBC1D24 gene inhibit this process, thereby causing neurodegeneration and epilepsy. Fruit flies with a defect in Skywalker, the fruit fly variant of TBC1D24, are being used as a model for neurodegeneration. Researchers from VIB and KU Leuven have succeeded in completely suppressing neurodegeneration in such fruit flies, by partially inhibiting the breakdown of 'defective' proteins in brain cells.

(MEMPHIS, Tenn. - November 24, 2014) Most long-term survivors of retinoblastoma, particularly those who had been diagnosed with tumors by their first birthdays, have normal cognitive function as adults, according to a St. Jude Children's Research Hospital study. The research, which appears in the current issue of the journal Cancer, found that the vast majority of survivors work full time, live independently and fulfill other milestones of adult life.

Scientists have discovered a gene that protects people against one of the major causes of stroke in young and middle-aged adults and could hold the key to new treatments.

Researchers from Royal Holloway, University of London, together with an international team from across the United States and Europe, have found that people with a specific variant of a gene, known as PHACTR1, are at reduced risk of suffering cervical artery dissection, which is caused by a tear in an artery that leads to the brain.

After more than six years of intensive effort, and repeated failures that made the quest at times seem futile, Harvard Stem Cell Institute (HSCI) researchers at Boston Children's Hospital (BCH) and Harvard's Department of Stem Cell and Regenerative Biology (HSCRB) have successfully converted mouse and human skin cells into pain sensing neurons that respond to a number of stimuli that cause acute and inflammatory pain.
