(Press-News.org) New Rochelle, NY, September 26, 2013—Traumatic brain injury (TBI) during childhood can have long-term effects on cognitive and psychosocial functioning, including poor academic achievement. Pediatric TBI can cause significant deficits in working memory, as demonstrated in a study published in Journal of Neurotrauma, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Neurotrauma website at http://www.liebertpub.com/neu.
Working memory is the ability to collect, retain, and use information needed to perform tasks and respond to immediate demands. Amery Treble and coauthors from University of Houston, Texas and University of Texas Health Science Center at Houston used brain imaging studies to measure verbal and visuospatial working memory in a group of children who sustained TBI and a control group who did not. The comparison showed poorer visuospatial working memory in the pediatric TBI group, which was associated with disruptions in brain connectivity between neural networks that underlie working memory.
In the article "Working Memory and Corpus Callosum Microstructural Integrity after Pediatric Traumatic Brain Injury: A Diffusion Tensor Tractography Study," the authors propose that the identification of neuroanatomical biomarkers indicative of these changes in brain microstructure might allow for early identification of children at increased risk for impaired working memory and for earlier intervention.
"While confirming the longstanding belief that the corpus callosum is consistently involved with traumatic brain, this study's exquisite regionally specific analyses of callosal integrity, together with its evaluation of working memory in a pediatric brain-injured population, make this a particularly important contribution to the field of pediatric TBI," says John T. Povlishock, PhD, Editor-in-Chief of Journal of Neurotrauma and Professor, VCU Neuroscience Center, Medical College of Virginia, Richmond.

Beautiful brushstrokes drawn from data
2013-09-26
A good painter uses simple strokes of a brush to bring texture, contrast and depth to a blank canvas. In comparison, computer programs can have difficulty reproducing the complex and varied forms of brushstrokes, and often require painstaking effort to mimic a brief sweep of paint.
Now, a team of researchers including scientists at Princeton University has developed a program that allows graphic artists to quickly and easily produce realistic brushstrokes on their computers. Called RealBrush, the program combines graphics algorithms with "Big Data" storage and retrieval ...
Penn researchers use Facebook data to predict users' age, gender and personality traits
2013-09-26
In the age of social media, people's inner lives are increasingly recorded through the language they use online. With this in mind, an interdisciplinary group of University of Pennsylvania researchers is interested in whether a computational analysis of this language can provide as much, or more, insight into their personalities as traditional methods used by psychologists, such as self-reported surveys and questionnaires.
In a recent study, published in the journal PLOS ONE, 75,000 people voluntarily completed a common personality questionnaire through a Facebook application ...
NASA views a transitioning Tropical-Storm Pabuk
2013-09-26
Typhoon Pabuk weakened and the core of the storm was changing from a warm core tropical system to a cold core low pressure system as it continued paralleling the coast of Japan on Sept. 26. NASA's Aqua satellite provided a visible image of the transforming storm that had lost its eye.
On Sept. 26, 2013 at 03:55 UTC/Sept. 25 at 11:55 p.m. EDT, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite captured a visible image of Tropical Storm Pabuk skirting eastern Japan. MODIS imagery also showed a steady influx of cold air stratocumulus ...
Future sea level rises should not restrict new island formation in the Maldives
2013-09-26
The continued accumulation of sand within the iconic ring-shaped reefs inside Maldivian atolls could provide a foundation for future island development new research suggests. Islands like the Maldives are considered likely to be the first to feel the effects of climate change induced sea level rise, with future island growth essential to counter the threat of rising sea levels.
The study published in the journal Geology, and carried out by researchers from the University of Exeter in collaboration with the University of Auckland, James Cook University, the National Institute ...
Scripps research institute scientists discover important wound-healing process
2013-09-26
LA JOLLA, CA -- September 26, 2013 -- Scientists at The Scripps Research Institute (TSRI) have discovered an important process by which special immune cells in the skin help heal wounds. They found that these skin-resident immune cells function as "first responders" to skin injuries in part by producing the molecule known as interleukin-17A (IL-17A), which wards off infection and promotes wound healing.
"This appears to be a critical and unique component of mammals' defense against skin wounds, and we hope that it will point the way towards better therapies for people ...
Microbes facilitate the persistence and spread of invasive plant species by changing soil chemistry
2013-09-26
Invasive species are among the world's greatest threats to native species and biodiversity. Once invasive plants become established, they can alter soil chemistry and shift nutrient cycling in an ecosystem. This can have important impacts not only on plant composition, diversity, and succession within a community, but also in the cycling of critical elements like carbon and nitrogen on a larger, potentially even global, scale. Clearly, both native and exotic plants form intimate relationships with bacteria in the soil that facilitate the extraction and conversion of elements ...
Colorectal surgeons develop a novel tool for measuring quality and outcomes
2013-09-26
Since the publication in 2000 of a report titled "To Err is Human" by the Institute of Medicine which called for a reduction in preventable medical errors, there has been an increasing demand for making improvements in the quality and measurement of health care outcomes. Although many measures have been developed, they tend to be complex, labor intensive, have an unclear relationship with improved outcomes, and concentrate on processes of care rather than clinical outcomes.
In a new paper published online by the Annals of Surgery, physician-researchers at University Hospitals ...
First long temperature reconstruction for the eastern Mediterranean based on tree rings
2013-09-26
For the first time a long temperature reconstruction on the basis of stable carbon isotopes in tree rings has been achieved for the eastern Mediterranean. An exactly dated time series of almost 900 year length was established, exhibiting the medieval warm period, the little ice age between the 16th and 19th century as well as the transition into the modern warm phase. Moreover, Ingo Heinrich from the GFZ German Research Centre for Geosciences and colleagues revealed that the modern warming trend cannot be found in the new chronology. "A comparison with seasonal meteorological ...
Eating fish, nuts may not help thinking skills after all
2013-09-26
MINNEAPOLIS – Contrary to earlier studies, new research suggests that omega-3 fatty acids may not benefit thinking skills. The study is published in the September 25, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. Omega-3s are found in fatty fish such as salmon and in nuts.
"There has been a lot of interest in omega-3s as a way to prevent or delay cognitive decline, but unfortunately our study did not find a protective effect in older women. In addition, most randomized trials of omega-3 supplements have not found an effect," ...
Missouri ponds provide clue to killer frog disease
2013-09-26
The skin fungus, Batrachochytrium dendrobatidis (Bd), also known as amphibian chytrid, first made its presence felt in 1993 when dead and dying frogs began turning up in Queensland, Australia. Since then it has sickened and killed frogs, toads, salamanders and other amphibians worldwide, driving hundreds of species to extinction.
As a postdoctoral researcher Kevin Smith studied Bd in South Africa, home to the African clawed frog, a suspected vector for the fungus. When he took a position at Washington University in St. Louis, where he is now interim director of the Tyson ...
