(Press-News.org) West Orange, NJ. April 30, 2014. Multiple sclerosis researchers have found that brain reserve and cognitive reserve confer a long-term protective effect against cognitive decline: Sumowski JF, Rocca MA, Leavitt VM, Dackovic J, Mesaros S, Drulovic J, Deluca J, Filippi M. Brain reserve and cognitive reserve protect against cognitive decline over 4.5 years in MS. Neurology. 2014 Apr 18. doi: 10.1212/WNL.0000000000000433 [Epub ahead of print]. James Sumowski, PhD, lead author of the article, and John DeLuca, PhD, are at Kessler Foundation. Co-authors are from the Manhattan Memory Center, New York, NY, the San Raffaele Scientific Institute, Milan, Italy, and the University of Belgrade, Serbia. Neurology is the official journal of the American Academy of Neurology. Dr. Sumowski presented this research at the 2014 AAN conference in Philadelphia.
"Our research aims to answer these questions," explained Dr. DeLuca. "Why do some people with MS experience disabling symptoms of cognitive decline, while others maintain their cognitive abilities despite neuroimaging evidence of significant disease progression? Can the theories of brain reserve and cognitive reserve explain this dichotomy? Can we identify predictors of cognitive decline?"
In this study, memory, cognitive efficiency, vocabulary (a measure of intellectual enrichment/cognitive reserve), brain volume (a measure of brain reserve), and disease progression on MRI, were evaluated in 40 patients with MS at baseline and at 4.5-year followup. After controlling for disease progression, scientists looked at the impact of brain volume and intellectual enrichment on cognitive decline.
Results supported the protective effects of brain reserve and cognitive reserve," noted Dr. Sumowski. "Patients with greater intellectual enrichment experienced lesser degrees of cognitive decline. Those with greater brain reserve showed a protective effect for cognitive efficiency. This study not only confirms these protective effects of brain and cognitive reserve, it shows that these beneficial effects persist for years."

'US Should significantly reduce rate of incarceration,' says new report
2014-04-30
WASHINGTON -- Given the minimal impact of long prison sentences on crime prevention and the negative social consequences and burdensome financial costs of U.S. incarceration rates, which have more than quadrupled in the last four decades, the nation should revise current criminal justice policies to significantly reduce imprisonment rates, says a new report from the National Research Council.
A comprehensive review of data led the committee that wrote the report to conclude that the costs of the current rate of incarceration outweigh the benefits. The committee recommended ...
Seeing the bedrock through the trees
2014-04-30
University of California, Berkeley, geologist William Dietrich pioneered the application of airborne LIDAR – light detection and ranging – to map mountainous terrain, stripping away the vegetation to see the underlying ground surface.
But that didn't take him deep enough. He still couldn't see what was under the surface: the depth of the soil, the underlying weathered rock and the deep bedrock.
He and geology graduate student Daniella Rempe have now proposed a method to determine these underground details without drilling, potentially providing a more precise way to ...
Hope for better drugs to treat stroke and heart attacks
2014-04-30
An international team of researchers in cooperation with the University of Bonn has taken two "snapshots" of a receptor which are of critical importance for blood coagulation. The scientists now hope to be able to develop novel drugs using these results. These include tailor-made blood-thinning substances for heart attack and stroke patients whose effects are reversible and better controllable than those of current therapies. The researchers are presenting their results in the renowned journal "Nature."

Prostate cancer and blood lipids share genetic links
2014-04-30
Numerous studies have suggested a relationship between cardiovascular disease risk factors and prostate cancer. A new study by researchers at the University of California, San Diego School of Medicine, with colleagues in Norway, significantly refines the association, highlighting genetic risk factors associated with low density lipoprotein (LDL) cholesterol and triglycerides as key players and identifying 17 related gene loci that make risk contributions to levels of these blood lipids and to prostate cancer
The findings, published in the April 30, 2014 online issue of ...

Neanderthals were not inferior to modern humans, says CU-Boulder study
2014-04-30
The embargo has been lifted for the article, 'Neandertal Demise: An Archaeological Analysis of the Modern Human Superiority Complex.'
If you think Neanderthals were stupid and primitive, it's time to think again.
The widely held notion that Neanderthals were dimwitted and that their inferior intelligence allowed them to be driven to extinction by the much brighter ancestors of modern humans is not supported by scientific evidence, according to a researcher at the University of Colorado Boulder.
Neanderthals thrived in a large swath of Europe and Asia between about ...

Throwing injuries no longer just for the pros
2014-04-30
ROSEMONT, Ill.—Baseball season is back and so are the injuries. But, elbow injuries, once seen as a problem for professional athletes, are becoming more prevalent among high school and middle school athletes due to increased play and competition at the youth level. Repetitive stress to a pitcher's ulnar collateral ligament (UCL)—an important stabilizing ligament of the elbow joint—can lead to pain and eventually to the inability to pitch and throw.
According to a literature review in the May 2014 issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS), ...
Research finds a way to protect crops from pests and disease
2014-04-30
A team of international researchers has uncovered a mechanism by which plants are able to better defend themselves against disease-causing pathogens.
The work, led by Dr Jurriaan Ton and Dr Estrella Luna at the University of Sheffield, has identified the key receptor binding a chemical called BABA (β-aminobutyric acid) which is boosting plant immunity.
BABA has long been known for its protective effects against devastating plant diseases, such as potato blight, but has so far not been used widely in crop protection because of undesirable side effects.
"We have ...
