Nearly One Third Of US Combat Soldiers Suffer Traumatic Brain Injury
Date: Feb-08-2013U.S. soldiers in combat often suffer constricted blood vessels and increased pressure in the brain - significant complications of traumatic brain injuries, according to research presented at the American Stroke Association's International Stroke Conference 2013. "Research shows that traumatic brain injury is a hallmark of recent military conflicts, affecting nearly a third of all wounded soldiers," said Alexander Razumovsky, Ph.D., lead researcher and director of Sentient NeuroCare Services in Hunt Valley, Md. Constricted blood vessels in the brain are cerebral vasospasm...
Adult Stroke Survivors Who Practice Tai Chi May Be At Reduced Risk For Falls
Date: Feb-08-2013Tai Chi may reduce falls among adult stroke survivors, according to research presented at the American Stroke Association's International Stroke Conference 2013. Compared to survivors receiving usual care or participating in a national fitness program for Medicare-eligible adults called SilverSneakers®, those practicing Tai Chi had the fewest falls. Tai Chi is a martial art dating back to ancient China. It includes physical movements, mental concentration and relaxed breathing. "Learning how to find and maintain your balance after a stroke is a challenge," said Ruth E...
What Makes People Think And Behave Differently? Clues Provided By Brain Research
Date: Feb-08-2013Differences in the physical connections of the brain are at the root of what make people think and behave differently from one another. Researchers reporting in the Cell Press journal Neuron shed new light on the details of this phenomenon, mapping the exact brain regions where individual differences occur. Their findings reveal that individuals' brain connectivity varies more in areas that relate to integrating information than in areas for initial perception of the world...
Better Awareness Of Internal Bodily Signals Like Heartbeat Linked To Lower Levels Of Self-Objectification
Date: Feb-08-2013Women who are more aware of their bodies from within are less likely to think of their bodies principally as objects, according to research published in the open access journal PLOS ONE by Vivien Ainley and Manos Tsakiris from the Department of Psychology at Royal Holloway, University of London. The authors asked healthy female student volunteers aged between 19 - 26 to concentrate and count their own heartbeats, simply by "listening" to their bodies...
Persistent Organic Pollutants In The Body Linked To The Development Of Type 2 Diabetes
Date: Feb-08-2013A study conducted at the University of Granada has revealed that there is a direct relationship between exposure to pesticides (Persistent Organic Pollutants, CPOs) in food, air and water and prevalence of type 2 diabetes in adults, regardless of age, gender and body mass index. These substances tend to concentrate in body fat, and they might be one of the reasons why obese people are more likely to develop diabetes, since the more fat the higher the COP concentrations in the body...
In Lung Cancer, RNA Promotes Metastasis
Date: Feb-08-2013The vast majority - approximately 80 percent - of our DNA does not code for proteins, yet it gets transcribed into RNA. These RNA molecules are called non-coding and fulfill multiple tasks in the cell. Alongside a well-studied group of small RNAs, there is also a class of so-called long non-coding RNAs consisting of more than 200 nucleotides. Long non-coding RNAs regulate cellular processes such as cell cycle, growth and cell death. Therefore, it came as no surprise that many of these controlling molecules are linked to the progression of cancer...
Bleeding Strokes Occur At Earlier Age, Independent Of Meth Use, In Native Hawaiians
Date: Feb-08-2013Native Hawaiians and Pacific Islanders have more bleeding strokes at an earlier age than other people independent of methamphetamine abuse, according to research presented at the American Stroke Association's International Stroke Conference 2013. "Drug abuse is a huge problem here and it definitely is a cause of hemorrhagic stroke," said Kazuma Nakagawa, M.D., lead investigator and assistant professor of medicine at the University of Hawaii. "But Native Hawaiians and Pacific Islanders are experiencing this form of stroke at a younger age even without methamphetamine use...
New Molecular Inhibitors Successfully Hit Difficult Cancer Target
Date: Feb-08-2013Early laboratory tests are the first to successfully use an experimental molecular therapy to block a hard-to-target part of a protein complex linked to several types of invasive cancer. Scientists report online in PNAS Early Edition the rational design of a small-molecule inhibitor they call Y16. In laboratory tests, the inhibitor helped stop the spread of cultured human breast cancer cells, especially when it was used with another compound known as Rhosin/G04...
Imaging Technologies Transformed By New Modeling Approach
Date: Feb-08-2013Researchers are improving the performance of technologies ranging from medical CT scanners to digital cameras using a system of models to extract specific information from huge collections of data and then reconstructing images like a jigsaw puzzle. The new approach is called model-based iterative reconstruction, or MBIR...
Unexpected Chemical Connection Between Hormone Pathways Revealed By Tiny Weed
Date: Feb-08-2013You might think you have nothing in common with mustard except hotdogs. Yet based on research in a plant from the mustard family, Salk scientists have discovered a possible explanation for how organisms, including humans, directly regulate chemical reactions that quickly adjust the growth of organs. These findings overturn conventional views of how different body parts coordinate their growth, shedding light on the development of more productive plants and new therapies for metabolic diseases...
