Researchers from the Polytechnic University of Valencia (UPV) have produced a new league table of Spanish savings banks based on economic, financial and social criteria. This is the first study of these characteristics carried out in Spain, and the data used come from the savings banks' annual accounts for 2007. "All the banking sector rankings previously produced have revolved around a single variable, such as size, number of assets or number of deposits, meaning they fail to give an overall vision of the organisation as a whole", Fernando García, co-author of the study ...

(Boston) – Boston Medical Center (BMC) doctors have proven the reliability of the Boston Bowel Preparation Scale (BBPS), a tool that assesses the cleanliness of the colon during colonoscopies. This study, published in the October 2010 issue of the journal Gastrointestinal Endoscopy, demonstrates the scale's accuracy and could become an international standardized tool to rate colon cleanliness during colonoscopy. Audrey Calderwood, MD, a physician in BMC's section of gastroenterology and an assistant professor at Boston University School of Medicine (BUSM), is lead author ...

(Rosemont, IL) Oct. 1 – For the past three decades, saturated fat has been considered a major culprit of cardiovascular disease (CVD) and as a result dietary advice persists in recommending reduced consumption of this macronutrient. However, new evidence shows that saturated fat intake has only a very limited impact on CVD risk -- causing many to rethink the "saturated fat is bad" paradigm. A series of research articles published in the October issue of Lipids provides a snapshot of recent advances in saturated fat and health research, based on science presented at ...

The U.S. Department of Agriculture (USDA) today released a new study by scientists and conservationists showing that non-federal rangelands in the Western United States are productive, but that non-native grasses and shrubs pose a potential threat to the rangelands' productivity. "American ranchers and farmers are at the front line of the effort to protect the health and productivity of our western rangelands," said Agriculture Secretary Tom Vilsack. "This new study not only provides valuable information about the current state of these lands, but also sets a baseline ...

New York, 1 October, 2010 – A special article published today in the journal Nutrition sharply criticizes the recent Report of the 2010 Dietary Guidelines Advisory Committee (DGAC). Authors Hite et al. argue the Report fails to conform to the standards of evidence-based medicine, despite its claimed reliance on a newly created USDA Nutrition Evidence Library. The authors call the DGAC to task for failing to consider recent scientific results while at the same time further confusing the American public. The Dietary Guidelines are the basis for the USDA Food Pyramid, and ...

Researchers at the National Institutes of Health have found that variations in a gene for an enzyme involved in cell energy metabolism appear to increase the risk for prostate cancer. The genetic variations all impair the enzyme phosphodiesterase 11A (PDE11A), which helps regulate a cell's responses to hormones and other signals. Previous studies by NIH researchers have linked genetic variations that inactivate PDE11A with increased susceptibility to testicular cancer and adrenal tumors The researchers found that a group of men with prostate cancer were nearly four ...

An analysis of geological records that preserve details of the last known period of global warming has revealed 'startling' results which suggest current targets for limiting climate change are unsafe. The study by climate change experts at the University of Exeter has important implications for international negotiators aiming to agree binding targets for future greenhouse gas emission targets. Professor Chris Turney and Dr Richard Jones, both from the University's Department of Geography, have reported a comprehensive study of the Last Interglacial, a period of warming ...

The convergence in the coming year of three cyclical conditions affecting ocean temperatures and weather is likely to create unprecedented challenges for states that depend on water from the Colorado River, a new UCLA study suggests. "If I were concocting a recipe for a perfect drought, this would be it," said Glen MacDonald, co-author of the study and director of UCLA's Institute of the Environment and Sustainability. Along with a former graduate student, MacDonald has found that the combination of La Niña with two less commonly known ocean conditions — the Pacific ...

CORVALLIS, Ore. – Faster development of the promising field of cellulosic biofuels – the renewable energy produced from grasses and trees – is being significantly hampered by a "deep and thorny regulatory thicket" that makes almost impossible the use of advanced gene modification methods, researchers say. In a new study published today in the journal BioScience, scientists argue that major regulatory reforms and possibly new laws are needed to allow cellulosic bioenergy to reach its true potential as a form of renewable energy, and in some cases help reduce greenhouse ...

BUFFALO, N.Y. -- Biomedical researchers at the University at Buffalo have engineered adult stem cells that scientists can grow continuously in culture, a discovery that could speed development of cost-effective treatments for diseases including heart disease, diabetes, immune disorders and neurodegenerative diseases. UB scientists created the new cell lines – named "MSC Universal" – by genetically altering mesenchymal stem cells, which are found in bone marrow and can differentiate into cell types including bone, cartilage, muscle, fat, and beta-pancreatic islet cells. ...

ROCHESTER, Minn. -- In a review article published in the October issue of Mayo Clinic Proceedings,(http://www.mayoclinicproceedings.com) Mayo Clinic physicians differentiate the ethical and legal permissibility of withholding or withdrawing life-sustaining treatments and accepted comfort measures, specifically palliative sedation, from that of physician-assisted suicide or euthanasia. Physician reviewers find that palliative sedation has an important place on the continuum of appropriate palliative care. "At the end of life, patient goals often shift to comfort, and removal ...

What does it take to save a species in the 21st century? The specter of climate change, with predicted losses to biodiversity as high as 35 percent, has some scientists and managers considering taking their conservation strategies on the road. Managed relocation (MR) is literally the physical relocation of endangered or threatened species of plants and animals, by humans, to new, and foreign geographical climes. It addresses the concern that climate shifts may make many species' historical ranges environmentally inhospitable, and that the rapid speed of change and habitat ...
