CHG cloths more effective in reducing risk for acquiring HAIs Study shows 64 percent decreased risk of infection from MRSA or VRE May be beneficial for both ICU and general medical unit patients PROVIDENCE, R.I. – A new study from Rhode Island Hospital has found a reduced risk of hospital-acquired infections (HAI) when using two percent chlorhexidine gluconate (CHG) cloths for daily bathing instead of soap and water. The study found a 64 percent decrease in the risk of acquiring an infection from either methicillin-resistant Staphylococcus aureus (MRSA) or Vancomycin-resistant ...

The way the heart responds to an early beat is predictive of cardiac death, especially for people with no conventional markers of cardiovascular disease, according to new research from Washington University School of Medicine in St. Louis. The conventional risk factors, such as high cholesterol, smoking, diabetes and high blood pressure, account for many but not all deaths from cardiovascular causes. As a result, doctors are always searching for better ways to identify patients at risk of cardiac death. The new research indicates that an abnormal response to an early ...

GAINESVILLE, Fla. — University of Florida researchers say their supercomputer, named Novo-G, is the world's fastest reconfigurable supercomputer and is able to perform some important science applications faster than the Chinese supercomputer touted as the world's most powerful. In November, the TOP500 list of the world's most powerful supercomputers, for the first time ever, named the Chinese Tianhe-1A system at the National Computer Center in Tainjin, China as No. 1. In his state of the union speech, President Barack Obama noted, "Just recently, China became home ...

Alexandria, VA – The U.S. had two key strategic advantages over the Axis in World War II: oil and water. Although other factors played major roles in the U.S. and its allies winning the war, these two natural resources played a much larger role than recognized. World War II was the first highly mechanized war. In the March feature "How Oil and Water Helped the U.S. Win World War II," EARTH magazine explores how the abundance of domestic US oil and water in the South and Pacific Northwest drove not only tanks and planes, but also industrial production and technological ...

OAK BROOK, Ill. – Feb. 15, 2011 – Researchers from Korea report that, compared with conventional sedation, balanced propofol sedation (BPS) using propofol in combination with midazolam and meperidine, provided higher health care provider satisfaction, better patient cooperation, and similar adverse event profiles in patients undergoing therapeutic endoscopic procedures. This is the first prospective study of BPS in direct comparison with conventional sedation. The researchers note that this study provides further evidence to support the adoption of endoscopist-directed ...

The latest mashup technology and mobile applications make it possible to come up with solutions. Inspired by the UK website www.fixmystreet.com, the Fraunhofer Institute for Open Communication Systems FOKUS in Berlin is taking this approach further. Damage reports can be assigned GPS coordinates by cell phone and entered. The system then provides ...

You might think that a loving partner helps keep you on track—say, when you want to stick to your jogging or concentrate on your studies. But a new study in Psychological Science, a publication of the Association of Psychological Science, reports the opposite: Thinking about the support a significant other offers in pursuing goals can undermine the motivation to work toward those goals—and can increase procrastination before getting down to work. The study's authors, psychological scientists Gráinne M. Fitzsimons of Duke University and Eli J. Finkel of Northwestern University, ...

The auto industry faces major challenges. New models are entering the market at ever shorter intervals, products are becoming more complex, and the trend towards electric cars requires modified vehicle structures. European production sites are coming under increasing cost pressure from low-wage countries. Cost reductions, shorter production times, new materials and innovative assembly techniques are needed if companies are to remain competitive. To achieve these goals, 23 business and research organizations are participating in the EU's Pegasus project (www.pegasus-eu.net). ...

Just when everyone thought that almost every plant species on the Iberian Peninsula had been discovered, Spanish researchers have discovered Taraxacum decastroi and Taraxacum lacianense, two dandelions from the Pyrenees and the Cordillera Cantábrica mountain range, respectively. This finding confirms Spain's privileged position as a hotbed of biodiversity. "It's hard to find new species now in Spain. It depends on the complexity of the group of plants you study", Antonio Galán de Mera, lead author of the study and a researcher in the Department of Biology (Botany) at ...

WASHINGTON – A National Research Council committee asked to examine the scientific approaches used and conclusions reached by the Federal Bureau of Investigation during its investigation of the 2001 Bacillus anthracis mailings has determined that it is not possible to reach a definitive conclusion about the origins of the anthrax in letters mailed to New York City and Washington, D.C., based solely on the available scientific evidence. Findings of the committee's study include: The FBI correctly identified the dominant organism found in the letters as the Ames strain ...

Someday, that potted palm in your living room might go from green to white, alerting you to a variety of nasty contaminants in the air, perhaps even explosives. The stuff of science fiction you say? Not so, says a Colorado State University biologist whose research is funded in part by Homeland Security's Science and Technology Directorate (DHS S&T), as well as by the Defense Advanced Research Projects Agency (DARPA), the Office of Naval Research (ONR), and others. Dr. June Medford and her team in the Department of Biology at Colorado State have shown that plants ...

Interactions between proteins are of fundamental importance for a number of processes in virtually every living cell. However, in order for the proteins to carry out any biological function, they must first assume their specific three-dimensional shape. A number of reactions have been described in recent years, where one of the interaction partners does not assume its active structure until the actual binding process commences. It was still a great mystery, though, how the binding partners could actually recognize such unstructured proteins. Scientists led by Professor ...

Boston, MA – An estimated 10 million Americans suffer from knee osteoarthritis (OA), making it one of the most common causes of disability in the US. Due to obesity and symptomatic knee OA, Americans over the age of 50 will together lose the equivalent of 86 million healthy years of life, concluded researchers at Brigham and Women's Hospital (BWH), who investigated the potential gains in quality and quantity of life that could be achieved averting losses due to obesity and knee OA. These findings are published in the February 15 issue of Annals of Internal Medicine. "Reducing ...

While governments debate about potential policies that might curb the emission of greenhouse gases, new University of Washington research shows that the world is already committed to a warmer climate because of emissions that have occurred up to now. There would continue to be warming even if the most stringent policy proposals were adopted, because there still would be some emission of heat-trapping greenhouse gases such as carbon dioxide and methane. But the new research shows that even if all emissions were stopped now, temperatures would remain higher than pre-Industrial ...

Peer support offers promise as an effective, low-cost tool for fighting depression, a new study by the VA Ann Arbor Healthcare System and University of Michigan Health System finds. Programs in which patients and volunteers share information were found to reduce symptoms of depression better than traditional care alone and were about as effective as cognitive behavioral therapy, researchers found after analyzing 10 randomized trials of peer support interventions for depression dating from 1987 to 2009. The analysis was the first of its kind to look at peer support specifically ...

Up to two-thirds of California's 7 million uninsured residents will become eligible for health insurance coverage when health care reform is implemented in 2014, according to a new policy brief from the UCLA Center for Health Policy Research. The study draws on the latest data from the California Health Interview Survey (CHIS), which will be released shortly. The policy brief, "Two-thirds of California's 7 Million Uninsured May Obtain Coverage Under Health Care Reform," finds that 4.7 million Californians, including both adults and children, will likely be eligible ...

Abnormal heart rate turbulence is associated with an increased risk of heart disease death in otherwise low-risk older individuals, according to a study funded by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. This study appears in the Feb. 15 edition of the Journal of Cardiovascular Electrophysiology. Among the nearly 1,300 study participants, heart rate turbulence, which reflects how well the heart reacts to occasional premature contractions, was an even stronger heart disease risk factor than elevated levels of C-reactive ...

Basic and translational research on cancer, and development of new cancer therapeutics, has focused on different aspects of cancer cellular function. One area of focus is the life and death of a cancer cell. Apoptosis, also known as programmed cell death, is a fundamental process of cells including cancer cells. The signal transduction pathways of apoptosis involve many different proteins and their interactions with each other. Protein-protein interactions involved in these apoptotic signals, like those in many other biological processes, are often determined or influenced ...

An international team of astronomers has identified for the first time a thick stellar disc in the Andromeda galaxy, the nearest large spiral galaxy to our own Milky Way. The discovery of the thick disc, a major result from a five-year investigation, will help astronomers better understand the processes involved in the formation and evolution of large spiral galaxies like ours, according to the team, which includes UCLA research astronomer Michael Rich and colleagues from Europe and Australia. Using the Keck Telescope in Hawaii, the astronomers analyzed the velocities ...

HOUSTON - An essential protein for normal stem cell renewal also promotes the growth of breast cancer stem cells when it's overproduced in those cells, researchers at The University of Texas MD Anderson Cancer Center report in the February edition of Cancer Cell. In mouse and lab experiments, the team also discovered that two drugs block the cascade of molecular events that they describe in the paper, thwarting formation of breast tumor-initiating cells. "Overexpression of the EZH2 protein has been linked to breast cancer progression, but the molecular details of that ...
