Neuroimaging Study Shows Cold Reasoning, Hot Feelings Intimately Connected
Date: Mar-07-2013Kirk and Spock may not need a Vulcan mind meld to share cognition: Virginia Tech Carilion Research Institute scientists have found that our cold reasoning and hot feelings may be more intimately connected than previously thought. "We tend to believe we have rational parts, like Spock, and separate emotional parts, like Kirk. But our research suggests that's not true," said Read Montague, director of the Human Neuroimaging Laboratory at the Virginia Tech Carilion Research Institute, who led the study. "We're all a combination of logical Spock and intuitive Kirk...
Potential Shift In Burden Of Pneumococcal Disease Suggested By New Study
Date: Mar-07-2013New studies revealed by Latin American researchers and global health leaders suggest that the highest burden of deadly pneumococcal disease in Latin America may be shifting to adults as countries successfully immunize more infants with new vaccines. The experts called for increased disease monitoring and more surveillance to understand the full extent of pneumococcal disease in the Americas, including its economic impact, and to devise effective strategies to prevent it...
DNA Analysis Finds Human Y Chromosome Much Older Than Previously Thought
Date: Mar-07-2013A newly discovered Y chromosome places the most recent common ancestor for the Y chromosome lineage more 100,000 years before the oldest known anatomically modern human fossils. UA geneticists have discovered the oldest known genetic branch of the human Y chromosome - the hereditary factor determining male sex. The new divergent lineage, which was found in an individual who submitted his DNA to Family Tree DNA, a company specializing in DNA analysis to trace family roots, branched from the Y chromosome tree before the first appearance of anatomically modern humans in the fossil record...
Short Bouts Of Exercise Boost Self Control
Date: Mar-07-2013Increased blood and oxygen flow to pre-frontal area of brain may explain effects Short bouts of moderately intense exercise seem to boost self control, indicates an analysis of the published evidence in the British Journal of Sports Medicine. The resulting increased blood and oxygen flow to the pre-frontal cortex may explain the effects, suggest the researchers...
In The UK Disabled Employees Are At Double The Risk Of Being Attacked At Work
Date: Mar-07-2013Employees with disabilities are twice as likely to be attacked at work and they experience higher rates of insults, ridicule and intimidation, a new UK study has found. Researchers from Cardiff and Plymouth universities found that people with physical or psychological disabilities or long-term illness reported higher rates of 21 types of ill-treatment than other workers did, often from their managers and colleagues. These included being given impossible deadlines and being ignored, gossiped about or teased...
Clinical Pharmacist-Led Free Online Monitoring Program Helps Reduce Blood Pressure
Date: Mar-07-2013People with high blood pressure enrolled in a clinical pharmacist-led web-based monitoring program were more likely to lower their pressure to recommended level than people who did not use the program. The study was published in the American Heart Association journal Circulation: Cardiovascular Quality and Outcomes. The study, led by David J. Magid, M.D., M.P.H., at Kaiser Permanente Colorado in Denver, followed people who use the American Heart Association's Heart360 program...
Genetics Journal Highlights For March 2013
Date: Mar-07-2013Listed below are the selected highlights for the March 2013 issue of the Genetics Society of America's journal, Genetics.* ISSUE HIGHLIGHTS Cellular Genetics: Systems genetics implicates cytoskeletal genes in oocyte control of cloned embryo quality, pp. 877-896 Yong Cheng, John Gaughan, Uros Midic, Zhiming Han, Cheng-Guang Liang, Bela G. Patel, and Keith E. Latham Cloning by somatic cell nuclear transfer is a powerful technology that offers a unique means of dissecting developmental processes. This article reveals oocyte-expressed genes that support early cloned embryo development...
Bitter Compounds Have The Potential To Be Used Therapeutically To Relax Airways
Date: Mar-07-2013That kale and bitter melon you are eating may someday save your life. An interdisciplinary team of scientists at the University of Massachusetts Medical School have taken a step forward in understanding how the substances that give some foods their bitter flavor also act to reverse the contraction of airway cells, a process known as bronchodilation. This effect may one day be harnessed to provide improved treatments for airway obstructive diseases such as asthma and chronic obstructive pulmonary disease. The findings were published in the open access journal PLOS Biology...
Identification Of Genetic Mutation May Open Up New Treatment Options For Type 1 Diabetes
Date: Mar-07-2013In type 1 diabetes, the immune system destroys insulin-producing cells in the pancreas, but the precise cause has not been clear. A study published by Cell Press in Cell Metabolism reveals that a single mutation in the "longevity gene" SIRT1 can cause type 1 diabetes in humans. The findings unearth the role this gene plays in human autoimmunity and disease and also offer new avenues for treating a range of autoimmune disorders...
Stroke Or Benign Dizziness? Portable Device Diagnoses Stroke With 100 Percent Accuracy
Date: Mar-07-2013A bedside electronic device that measures eye movements can successfully determine whether the cause of severe, continuous, disabling dizziness is a stroke or something benign, according to results of a small study led by Johns Hopkins Medicine researchers. "Using this device can directly predict who has had a stroke and who has not," says David Newman-Toker, M.D., Ph.D., an associate professor of neurology and otolaryngology at the Johns Hopkins University School of Medicine and leader of the study described in the journal Stroke...
