A new study from the University of Haifa has found that walking around the ward during hospitalization significantly reduces the length of the older patient's stay. "Given the over-occupancy of many hospitals, this finding can be of great importance," the researchers stated. Walking around the ward during hospitalization reduces the length of geriatric patients' stay in internal wards. This has been shown in a new study by Dr. Efrat Shadmi and Dr. Anna Zisberg of the University of Haifa's Department of Nursing, funded by the Israeli Science Foundation and published in ...

Nearly half of all women scientists and one-quarter of male scientists at the nation's top research universities said their career has kept them from having as many children as they had wanted, according to a new study by Rice University and Southern Methodist University (SMU). The study, "Scientists Want More Children," was authored by sociologists Elaine Howard Ecklund of Rice and Anne Lincoln of SMU and appears in the current issue of the journal PLoS ONE. For the past three years, Ecklund and Lincoln have been studying what junior and senior scientists in physics, ...

U.S. Department of Agriculture (USDA) scientists are using a technology known as "Fourier transform infrared-attenuated total reflection" (FTIR-ATR) spectroscopy to rapidly identify with 95 percent accuracy citrus plant leaves infected with the devastating disease known as citrus greening. Scientists from the Agricultural Research Service (ARS) Subtropical Plant Pathology Research Unit in Fort Pierce, Fla., and the agency's Quality and Safety Assessment Research Unit in Athens, Ga., collaborated on the use of FTIR-ATR spectroscopy to identify citrus greening in plants. ...

OTTAWA – August 8, 2011 – There are increasing pressures for health care providers to make individual-level data readily available for research and policy making. But Canadians are more likely to allow the sharing of their personal data if they believe that their privacy is protected. A new report by Dr. Khaled El Emam, the Canada Research Chair in Electronic Health Information at the University of Ottawa and the Children's Hospital of Eastern Ontario Research Institute, suggests that Canadians can be uniquely identified from their date of birth, postal code, and gender. ...

A liquid does not have to be a disordered bunch of particles: A team of researchers at Vienna University of Technology (TU Vienna) and the University of Vienna has discovered intriguing structures formed by tiny particles floating in liquids. Under mechanical strain, particle clusters in liquids can spontaneously form strings and dramatically alter the properties of the liquid. What is common to blood, ink and gruel? They are all liquids in which tiny particles are suspended – so called "colloids". In some of these liquids, the particles form groups (clusters), which ...

Hospitals vary markedly when it comes to the rate at which diagnostic coronary angiography or catheterization – an invasive procedure that allows doctors to see the vessels and arteries leading to the heart – actually finds obstructive coronary artery disease (CAD) in people without known heart disease. In fact, while some U.S. hospitals report that 100 percent of patients undergoing this procedure were found to have CAD, others had rates as low as 23 percent, meaning the majority of patients selected for elective catheterization did not have blockages, according to ...

CINCINNATI—A new study supports the use of a DNA-based "biomarker" blood test as a complement to the prostate-specific antigen (PSA) test currently offered to screen men for prostate cancer. University of Cincinnati (UC) researchers report their findings online ahead of print in the British Journal of Cancer. Researchers conducted a meta-analysis of existing published data related to DNA methylation in bodily fluids. The goal was to evaluate a specific cancer biomarker—known as GSTP1—as a screening tool for prostate cancer. The study was a cross-disciplinary collaborative ...

Nearly half of men undergoing surgery for prostate cancer expect better recovery from the side effects of the surgery than they actually attain one year after the operation, a University of Michigan Comprehensive Cancer Center study finds. In addition, prior to surgery, a small proportion of men had expected to have better urinary continence and sexual functions a year after the surgery than they had before it – the exact opposite of what typically happens. "This is a belief that does not reflect preoperative counseling which, on the contrary, alerts men to urinary ...

FINDINGS: Whitehead Institute researchers have uncovered a novel association between two fungal recognition receptors on the surface of certain immune cells, called macrophages. The interaction of these receptors (dectin-1 and galectin-3) sheds new light on how the innate immune system discriminates between non-pathogenic and pathogenic fungi. RELEVANCE: Invasive fungal infections are a rising source of morbidity and mortality in healthy individuals, as well as in patients suffering from chronic diseases, such as cancer or AIDS. Research into the role of the dectin-1/galectin-3 ...

Researchers have found a potential new source for sexual problems among middle-aged and older men: the relationships between their female partners and the men's closest friends. A study published Monday, August 8, by scholars at the University of Chicago and Cornell University has found a connection between erectile dysfunction and the social networks shared by heterosexual men and their partners. They describe the situation as "partner betweenness." In such cases, a man's female partner has stronger relationships with his confidants than the man does — in effect, the ...

Modifying stomach acid levels may not be enough to treat symptoms in neonates suspected of having gastroesophageal reflux disease. According to a study from Nationwide Children's Hospital, this is the first study to classify reflux and its associated symptoms in neonates based on how and what is refluxed. Gastroesophageal reflux disease (GERD) is a frequent consideration in infants at risk of the life-threatening events chronic lung disease and dysphagia. Yet, the definition of GERD in neonates and infants and its treatment remains controversial. Acid suppressive medications ...

PHILADELPHIA - In a recent issue of Cancer Research, Daniel J. Powell, Jr., PhD, a research assistant professor of Pathology and Laboratory Medicine and Obstetrics and Gynecology at the Perelman School of Medicine at the University of Pennsylvania, showed for the first time that engineered human T cells can eradicate deadly human ovarian cancer in immune-deficient mice. Ovarian cancer is the most lethal reproductive cancer for women, with one-fifth of women diagnosed with advanced disease surviving five years. Nearly all ovarian cancers (90%) are characterized by their ...

PHILADELPHIA – In the latest issue of Nature, researchers at the Perelman School of Medicine at the University of Pennsylvania clarify the role of two proteins key to T-cell development. They found that one well-known protein called Notch passes off much of its role during T-cell maturation to another protein called TCF-1. T cells are required for many aspects of immunity, and understanding how these proteins influence the production of infection-fighting cells could improve treatments for immune-suppressed patients. The research group, led by senior author Avinash Bhandoola, ...

Almost everything we do leaves a digital trace, whether we send an email to a friend or make a purchase online. That includes law-abiding citizens — and criminals. And with digital information multiplying by the second, there are seemingly endless amounts of information for criminal investigators to gather and process. Now Prof. Irad Ben-Gal, Dr. Eugene Kagan and Ph.D. student Aviv Gruber of the Department of Industrial Engineering in Tel Aviv University's Ibi and Aladar Fleischman Faculty of Engineering are using these digital traces to catch criminals and beef up homeland ...

LOS ALAMOS, New Mexico, August 8, 2011—A Los Alamos National Laboratory research team has harnessed neutrons to view for the first time the critical role that an elusive molecule plays in certain biological reactions. The effort could aid in treatment of peptic ulcers or acid reflux disease, or allow for more efficient conversion of woody waste into transportation fuels. In a paper appearing this week in Angewandte Chemie International Edition, Los Alamos researchers join an international team in describing the role played by the elusive hydronium ion in the transfer ...

It's pretty much a given that the more educated someone becomes, the more likely they are to question their religious beliefs, stop going to church and even abandon their faith entirely. Or is it? A new University of Nebraska-Lincoln study challenges that age-old notion with findings that show education actually has a positive effect on Americans' churchgoing habits, their devotional practices, their emphasis on religion in daily life and their support for religious leaders to weigh in on the issues of the day. The work, to be published in a forthcoming edition of ...

Former Tropical Storm Emily made a brief comeback this weekend after degenerating over the mountains of Hispaniola late last week, and NASA's Aqua satellite captured an image of Emily just after her "rebirth." At 5 p.m. EDT on Saturday, August 6, Emily became a tropical depression for the second time in her life about 70 miles west-northwest of Great Abaco Island, near 26.9 North and 78.1 West. She was moving to the north at 8 mph and had a minimum central pressure of 1012 millibars. Maximum sustained winds were 30 mph. At 18:25 UTC 2:25 p.m. EDT, the Moderate Resolution ...

CORVALLIS, Ore. – Researchers from a team funded by the National Science Foundation have examined some of last spring's massive tornado damage and conclude in a new report that more intensive engineering design and more rigorous, localized construction and inspection standards are needed to reduce property damage and loss of life. As one of the nation's most destructive tornado seasons in history begins to wane, and hurricane season approaches its peak, experts are working to determine if old, tried-and-true approaches to residential and small building construction are ...

Tropical Storm Muifa is filling up the Yellow Sea on NASA satellite imagery as it continues moving north today to a landfall in East China's Shandong province. NASA's Aqua satellite captured visible and infrared imagery that shows Muifa's cloud cover stretches across the Yellow Sea, from China to the west to South and North Korea to the east. At 18:25 UTC 2:25 p.m. EDT, the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Aqua satellite captured a visible image of Tropical Storm Muifa moving through the Yellow Sea on August 6 at10:50 p.m. EDT. ...

DETROIT – Prenatal pet exposure, a mother's delivery mode and race are influential factors in a child's risk of developing allergies by age 2, according to a Henry Ford Hospital study. In a study believed to be the first of its kind, Henry Ford researchers found that babies who have indoor prenatal pet exposure have a pattern of lower levels of the antibody Immunoglobulin E, or IgE, between birth and age 2. IgE is linked to the development of allergies and asthma. Key findings: IgE levels were 28 percent lower during infancy in babies who had indoor prenatal pet ...

Rosemont, Ill. – Patients receiving treatment for carpal tunnel syndrome (CTS) prefer to play a more collaborative role when it comes to making decisions about their medical or surgical care, according to the findings of an August 3rd issue of the Journal of Bone and Joint Surgery (JBJS). "While other studies have shown patients with potentially life-threatening conditions such as cancer tend to prefer a more passive role when it comes to decision-making, this study demonstrates that in carpal tunnel syndrome, which raises issues of quality of life rather than those ...
