Most community-based mental health providers are not well prepared to take care of the special needs of military veterans and their families, according to a new study by the RAND Corporation that was commissioned by United Health Foundation in collaboration with the Military Officers Association of America. The exploratory report, based on a survey of mental health providers nationally, found few community-based providers met criteria for military cultural competency or used evidence-based approaches to treat problems commonly seen among veterans. "Our findings suggest ...

A new study from The University of Texas at Arlington biologists examining non-genetic changes in water flea development suggests something human parents have known for years - ensuring a future generations' success often means sacrifice. Matthew Walsh, an assistant professor of biology, and his team looked at a phenomenon called "phenotypic plasticity" in the Daphnia abigua, or water flea. Phenotypic plasticity is when an organism changes its trait expressions or physical characteristics, or those of its offspring, because of external factors. In Daphnia, that can mean ...

Chemists at the University of Basel in Switzerland have succeeded in twisting a molecule by combining molecular strands of differing lengths. The longer strand winds around a central axis like a staircase banister, creating a helical structure that exhibits special physical properties. The results were published in the renowned scientific journal Angewandte Chemie International Edition. The chemistry of all substances is to a large extent defined by their spatial arrangement. Many molecules can be present in two forms (enantiomers), which behave like a person's right ...

November 12, 2014 - In preschool-aged children, a simple test performed in the ophthalmologist's or optometrist's office greatly overestimates the eye's ability to "flex and focus" in order to see small objects clearly, reports a study in the November issue of END ...

Nanomedicine is offering patients a growing arsenal of therapeutic drugs for a variety of diseases but often at a cost of thousands of dollars a month. Generics could substantially reduce the price tag for patients -- if only there were a well-defined way to make and regulate them. An article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, details the challenges on the road to generic nanodrugs. Matt Davenport, a C&EN contributing editor, points out that in small-molecule therapeutics -- aspirin, for example -- the active ...

The loss of eyesight, often caused by retinal degeneration, is a life-altering health issue for many people, especially as they age. But a new development toward a prosthetic retina could help counter conditions that result from problems with this crucial part of the eye. Scientists published their research on a new device, which they tested on tissue from laboratory animals, in the ACS journal Nano Letters. Yael Hanein and colleagues point out that a growing range of medical devices has become available to treat conditions, including visual impairment, that involve sending ...

COLUMBIA, MO. - Sugar-sweetened beverages are the largest source of added sugar in the diets of adolescents in the United States, and young adults ages 15-20 consume more of these drinks than any other age group, according to the Centers for Disease Control and Prevention. Adolescent obesity rates, which have quadrupled over the past thirty years, led to widespread scrutiny of added dietary sugars, especially those found in carbonated beverages. Now, MU researchers have found that short-term, moderate consumption of high-fructose and high-glucose beverages has little impact ...

INDIANAPOLIS -- People with a newly identified genetic variant perform better on certain types of memory tests, a discovery that may point the way to new treatments for the memory impairments caused by Alzheimer's disease or other age-associated conditions. In what the international research team is calling the largest study to date of human memory, an analysis of genomic data and memory test results from more than 14,000 older adults identified a location in the genome that was associated with better memory performance. The researchers noted that the gene has not been ...

A study led by Massachusetts General Hospital (MGH) investigators has identified what appears to be a molecular switch controlling inflammatory processes involved in conditions ranging from muscle atrophy to Alzheimer's disease. In their report published in Science Signaling, the research team found that the action of the signaling molecule nitric oxide on the regulatory protein SIRT1 is required for the induction of inflammation and cell death in cellular and animal models of several aging-related disorders. "Since different pathological mechanisms have been identified ...

November 12, 2014 - "I am the smartest kid in class." We all want our kids to be self-confident, but unrealistic perceptions of their academic abilities can be harmful. These unrealistic views, a new study of eighth-graders finds, damage the a child's relationship with others in the classroom: The more one student feels unrealistically superior to another, the less the two students like each other. Katrin Rentzsch of the University of Bamberg in Germany first became interested in the effects of such self-perceptions when she was studying how people became labeled as ...

LOS ANGELES -- New research from Keck Medicine of the University of Southern California (USC) bolsters evidence that exposure to tobacco smoke and near-roadway air pollution contribute to the development of obesity. The study, to be posted online Wednesday, Nov. 12, 2014 in Environmental Health Perspectives, shows increased weight gain during adolescence in children exposed to secondhand tobacco smoke or near-roadway air pollution, compared to children with no exposure to either of these air pollutants. The study is one of the first to look at the combined effects on ...

Applying a thin film of metallic oxide significantly boosts the performance of solar panel cells--as recently demonstrated by Professor Federico Rosei and his team at the Énergie Matériaux Télécommunications Research Centre at Institut national de la recherche scientifique (INRS). The researchers have developed a new class of materials comprising elements such as bismuth, iron, chromium, and oxygen. These "multiferroic" materials absorb solar radiation and possess unique electrical and magnetic properties. This makes them highly promising for solar technology, ...

VCU Massey Cancer Center and VCU Institute of Molecular Medicine (VIMM) researchers discovered a unique approach to treating pancreatic cancer that may be potentially safe and effective. The treatment method involves immunochemotherapy - a combination of chemotherapy and immunotherapy, which uses the patient's own immune system to help fight against disease. This pre-clinical study, led by Paul B. Fisher, M.Ph., Ph.D., and Luni Emdad, M.B.B.S., Ph.D., found that the delivery of [pIC]PEI - a combination of the already-established immune-modulating molecule, polyinosine-polycytidylic ...

High blood pressure - already a massive hidden killer in Nigeria - is set to sharply rise as the country adopts western lifestyles, a study suggests. Researchers who conducted the first up-to-date nationwide estimate of the condition in Nigeria warn that this will strain the country's already-stretched health system. Increased public awareness, lifestyle changes, screening and early detection are vital to tackle the increasing threat of the disease, they say. High blood pressure - also known as hypertension - is twice as high in Nigeria compared with other East ...

Scientists have demonstrated for the first time that a single-dose, needleless Ebola vaccine given to primates through their noses and lungs protected them against infection for at least 21 weeks. A vaccine that doesn't require an injection could help prevent passing along infections through unintentional pricks. They report the results of their study on macaques in the ACS journal Molecular Pharmaceutics. Maria A. Croyle and colleagues note that in the current Ebola outbreak, which is expected to involve thousands more infections and deaths before it's over, an effective ...

Geneticists at Heidelberg University Hospital's Department of Molecular Human Genetics have used a new mouse model to demonstrate the way a certain genetic mutation is linked to a type of autism in humans and affects brain development and behavior. In the brain of genetically altered mice, the protein FOXP1 is not synthesized, which is also the case for individuals with a certain form of autism. Consequently, after birth the brain structures degenerate that play a key role in perception. The mice also exhibited abnormal behavior that is typical of autism. The new mouse ...

An electronic "tongue" could one day sample food and drinks as a quality check before they hit store shelves. Or it could someday monitor water for pollutants or test blood for signs of disease. With an eye toward these applications, scientists are reporting the development of a new, inexpensive and highly sensitive version of such a device in the journal ACS Applied Materials & Interfaces. S. V. Litvinenko and colleagues explain that an electronic tongue is an analytical instrument that mimics how people and other mammals distinguish tastes. Tiny sensors detect substances ...

The structure of a soccer player's face can predict his performance on the field--including his likelihood of scoring goals, making assists and committing fouls--according to a study led by a researcher at the University of Colorado Boulder. The scientists studied the facial-width-to-height ratio (FHWR) of about 1,000 players from 32 countries who competed in the 2010 World Cup. The results, published in the journal Adaptive Human Behavior and Physiology, showed that midfielders, who play both offense and defense, and forwards, who lead the offense, with higher FWHRs ...

Queensland University of Technology (QUT) researchers have found the habit of Googling for an online diagnosis before visiting the doctor can be a powerful predictor of infectious diseases outbreaks. Now studies by the same Brisbane-based researchers show combining information from monitoring internet search metrics such as Baidu (China's equivalent of Google), with a web-based infectious disease alert system from reported cases and environmental factors hold the key to improving early warning systems and reducing the deadly effects of dengue fever in China. Dr Wenbiao ...

A new peer-reviewed study found that people are contaminated with several toxic flame retardants rarely studied in the US, including one that has never before been detected in Americans called TCEP. Scientists tested urine samples of California residents for biomarkers of six chemicals, all of which were present. The scientists discovered a way to test for this class of toxic flame retardants (phosphates), which could open up a new wave of research into a group of pervasive flame retardants that were previously not studied nearly as much as some other flame retardants. ...

Depression causes an average of 10 lost working days per episode Managers report need for better legislation, training and counseling to tackle the problem Right Direction Initiative developed to increase awareness of depression, reduce stigma associated with the disease in the workplace, and encourage employees to increase help-seeking behaviors Canton, Ohio- November 12, 2014 - Nearly a quarter (23 percent) of U.S. respondents indicated they have been diagnosed with depression in their lifetime and two in five (nearly 40 percent) of those patients reported taking ...

Cities have more species diversity than you'd expect. A study of ants in Manhattan found not only a wide range of species, but also significant differences in the levels of biodiversity in different urban areas. "People don't think of cities as having ecology, and urban environments haven't been well studied," says Dr. Amy Savage, a postdoctoral biological sciences researcher at North Carolina State University and lead author of a paper on the work. "But protected areas, such as national parks, have been well studied. So we wanted to see if the theories developed to predict ...

ANN ARBOR, Mich. -- There's a cast of characters deep inside your ears -- many kinds of tiny cells working together to allow you to hear. The lead actors, called hair cells, play the crucial role in carrying sound signals to the brain. But new research shows that when it comes to restoring lost hearing ability, the spotlight may fall on some of the ear's supporting actors - and their understudies. In a new paper published online first by the Proceedings of the National Academy of Sciences, researchers from the University of Michigan Medical School, St. Jude Children's ...

New insights into how plants regulate their absorption of an essential nutrient could help avoid pollution caused by excess use of fertiliser. The findings could lead to the development of crop varieties that need less of the primary nutrient - nitrogen - than conventional crops. It could also inform how much nitrogen should be added to plant feed. This would allow optimum plant growth without producing excess nitrogen in run-off from fields, which is a major source of water pollution. Agricultural fertilisers typically contain high levels of nitrogen that boost ...
