They found that patients' brains were less well-connected than the brains of people without the disorder.http://www.eurekalert.org/pub_releases/2008-06/sumc-fci062508.php CCNY researchers demonstrate effectiveness of contrast agent Cytate in detectcing prostate cancer- June 26, 2008 Researchers at the Institute for Ultrafast Spectroscopy and Lasers at The City College of New York have conducted time-resolved fluorescence measurement and optical imaging studies that demonstrate the efficacy of Cytate as a fluorescence marker to detect prostate cancer. Cytate, a contrast agent that conjugates to receptors on prostate cancer cells, exhibited greater fluorescence when applied to cancerous prostate tissue as opposed to normal prostate tissue.http://www.eurekalert.org/pub_releases/2008-06/ccon-crd062608.php Study links gastric bypass surgery to increased risk of kidney stones- June 26, 2008 Morbidly obese patients who undergo a particular type of gastric bypass surgery called Roux-en-Y gastric bypass are at an increased risk of developing kidney stones -- small, pebble-like deposits that can result in severe pain and require an operation to remove them -- earlier than previously thought.http://www.eurekalert.org/pub_releases/2008-06/wsw-slg062508.php Why do people vote Genetic variation in political participation- June 26, 2008 A groundbreaking new study finds that genes significantly affect variation in voter turnout, shedding new light on the reasons why people vote and participate in the political system.http://www.eurekalert.org/pub_releases/2008-06/apsa-wdp062608.php New system devised to guide doctors treating patients with symptomatic myocardial bridging- June 26, 2008 What type of intervention, if any, should cardiologists offer their patients who have a heart abnormality called myocardial bridging and symptoms of heart problems A research team at Cedars-Sinai Medical Center, the University of Texas Medical Branch and RWTH Aachen University in Germany has developed a new classification system that may help guide decision-making.http://www.eurekalert.org/pub_releases/2008-06/cmc-nsd062608.php 'No men allowed' in women's secret world- June 26, 2008 From the Petri dish in the controlled environment of a sterile laboratory to the faraway fields of another country, virtually anything can be the topic of scientific study.
