Deployment to Operation Enduring Freedom or Operation Iraqi Freedom was not associated with suicide in a study of more than 3.9 million U.S. military personnel in the Air Force, Army, Marine Corps and Navy, according to an article published online by JAMA Psychiatry. The suicide rate among active duty U.S. military members has increased in the last decade and research on the potential effect of deployment to Operation Enduring Freedom (OEF) or Operation Iraqi Freedom (OIF) is limited, according to the study background. Mark A. Reger, Ph.D., of Joint Base Lewis-McChord, ...

First meta-analysis to look at quality of safety reporting in published reports of clinical trials of the drug finasteride for male pattern baldness Zero of 34 clinical trials had adequate safety reporting Available toxicity information in published reports of clinical trials is very limited, of poor quality and appears systematically biased CHICAGO --- Published reports of clinical trials provide insufficient information to adequately establish the safety of finasteride for treatment of hair loss in men, according to a new Northwestern Medicine study to be published ...

Those suffering from depressive symptoms have an increased risk for physical diseases, especially for arthrosis and arthritis. These findings were reported by researchers from the University of Basel and the Ruhr-University Bochum. Their results, based on data from 14,300 people living in Switzerland, have been published in the scientific journal "Frontiers in Public Health". Depression is one of the leading health risks and affects 350 million people worldwide. In Switzerland, around 400,000 people individuals suffer from it each year. Several studies in countries around ...

For the crew of the Starship Enterprise, Star Trek's "Tricorder" was an essential tool, a multifunctional hand-held device used to sense, compute, and record data in a threatening and unpredictable universe. It simplified a number of Starfleet tasks, scientific or combat-related, by beaming sensors at objects to obtain instant results. The Tricorder is no longer science fiction. An invention by Tel Aviv University researchers may be able to turn smartphones into powerful hyperspectral sensors, capable of identifying the chemical components of objects from a distance. ...

Low doses of the anti-cancer drug imatinib can spur the bone marrow to produce more innate immune cells to fight against bacterial infections, Emory researchers have found. The results were published March 30, 2015 in the journal PLOS Pathogens. The findings suggest imatinib, known commercially as Gleevec , or related drugs could help doctors treat a wide variety of infections, including those that are resistant to antibiotics, or in patients who have weakened immune systems. The research was performed in mice and on human bone marrow cells in vitro, but provides information ...

COLUMBIA, Mo. - A drug used for decades to treat leukemia may have other uses in the fight against cancer, researchers at the University of Missouri have found. Previously, doctors used 6-Thioguanine, or 6-TG, as a chemotherapy treatment to kill cancer cells in patients with leukemia. In recent years, many doctors have shelved 6-TG in exchange for newer drugs that are more effective. Now, Jeffrey Bryan, an associate professor of oncology at the MU College of Veterinary Medicine, and his colleagues found that 6-TG can not only kill cancer cells, but also works to change ...

College students may realize that texting in the shower or at a funeral is inappropriate, but many do it anyway, according to Penn State psychologists. "We have looked at inappropriate texting behavior -- texting while driving, for instance -- before, but what we wanted to find out is whether the people who are engaging in these forms of behavior even know whether or not it is the right thing to do," said Marissa Harrison, associate professor of psychology, Penn State Harrisburg. The researchers suggest that college students are not necessarily trying to create new ...

Why It's Not Time for Health Care Rationing Peter A. Ubel There is a notable change in professional debates about how to better control health care costs. Discussion of health care rationing has become much more muted. "I contend that debates about health care rationing have waned not because the need to ration has dwindled nor because ethical debates about how or whether to ration have been resolved," writes Peter A. Ubel. They have declined because the word "rationing" has been replaced by terms such as "value" that "are not burdened by emotional and historical baggage." ...

DETROIT - A new study by scientists at the Wayne State University School of Medicine demonstrates that communication between some of the brain's most important centers is altered in children with obsessive-compulsive disorder. The research led by the Department of Psychiatry and Behavioral Neuroscience's David Rosenberg, M.D., and Vaibhav Diwadkar, Ph.D., sheds significant light on our understanding of how brain networks contribute to obsessive-compulsive disorder in youth. The study included youth with a diagnosis of OCD and a comparison group free of psychiatric illness. ...

A Chemistry undergraduate at the University of York has helped to develop a new drug release gel, which may help avoid some of the side effects of painkillers such as ibuprofen and naproxen. In a final year project, MChem undergraduate student Edward Howe, working in Professor David Smith's research team in the Department of Chemistry at York looked for a way of eliminating the adverse side-effects associated pain-killing drugs, particularly in the stomach, and the problems, such as ulceration, this could cause patients. Supervised by PhD student Babatunde Okesola, whose ...

Andres Pinto, an orofacial pain and oral medicine specialist at Case Western Reserve University School of Dental Medicine, often feels like the doctor in the television series House, who solves medical mysteries each week. Pinto is among about 700 facial pain and oral medicine specialists nationally who patients often turn to when their own doctors are unable to identify and treat complex and rare medical conditions. In fact, according to a new study Pinto conducted with input from fellow members of the American Academy of Oral Medicine (AAOM), patients see, on average, ...

A small area in the midbrain known as the substantia nigra is the control center for all bodily movement. Increasing loss of dopamine-generating neurons in this part of the brain therefore leads to the main symptoms of Parkinson's disease - slowness of movement, rigidity and shaking. In recent years, there has been increasing scientific evidence suggesting that inflammatory changes in the brain play a major role in Parkinson's. So far, it has been largely unclear whether this inflammation arises inside the brain itself or whether cells of the innate immune system that ...

Large amount of fat in neck muscles predicts chronic pain, disability and PTSD Will enable earlier treatment for whiplash victims Fat indicates atrophy, shows the chronic pain is not psychological Whiplash affects more than 4 million Americans annually CHICAGO --- While most people should expect to fully recover from whiplash injuries within the first few months, about 25 percent have long-term pain and disability that lasts many months or years. Using special MRI imaging, Northwestern Medicine scientists have identified, within the first one and two weeks ...

EAST LANSING, Mich. --- America's welfare state is quietly evolving from needs-based to an employment-based safety net that rewards working families and fuels dreams of a better life, indicates a new study led by a Michigan State University scholar. The major reason: the little-known Earned Income Tax Credit, a $65 billion federal tax-relief program for poor, working families. The program has been expanded dramatically during the past 25 years, while cash welfare has been sharply curtailed. Reporting in the April issue of the American Sociological Review, Jennifer Sykes ...

ENVIRONMENT - Invertebrates' role in bioaccumulation ... By studying fish and invertebrates in a creek with known mercury contamination, researchers are gaining a better understanding of the relationship between the toxin in the stream and bioaccumulation in organisms. While mercury concentrations in East Fork Poplar Creek in Oak Ridge, Tenn., have decreased significantly over the last 30 years, levels in tissue from fish have remained the same or increased. To understand why, a team led by Monica Poteat of Oak Ridge National Laboratory is examining the intricacies of ...

WASHINGTON, DC, April 1, 2015 -- America's welfare state is quietly evolving from needs-based to an employment-based safety net that rewards working families and fuels dreams of a better life, indicates a new study led by a Michigan State University (MSU) scholar. The major reason: the little-known Earned Income Tax Credit (EITC), a $65 billion federal tax-relief program for poor, working families. The program has been expanded dramatically during the past 25 years, while cash welfare has been sharply curtailed. Reporting in the April issue of the American Sociological ...

Irvine, Calif., April 1, 2015 -- A pouchlike structure inside the heart's left atrial chamber in some people may explain strokes that otherwise lack an identifiable cause, according to UC Irvine School of Medicine researchers. Dr. Mark Fisher, a professor of neurology and pathology & laboratory medicine, and colleagues evaluated 75 stroke patients at UC Irvine Medical Center to learn whether this left atrial septal pouch could be a potent source of stroke-causing blood clots. Of the 23 patients who had experienced a stroke of undetermined origin (a "cryptogenic" stroke), ...

Jena (Germany) The "Villa trans lacum" at the eastern shore of the Laacher See (lake) in the volcanic part of the Eifel - a rural landscape in Germany - was a highly dangerous place. In the 19th century the Jesuit order bought the abbey Maria Laach and built a villa at the shore of the lake. This is where the friars congregated to pray far away from everyday life. But numerous Jesuits paid with their lives for the religious beliefs in the villa. Between 1864 and 1888 17 of them died in the building - literally in their sleep. "The monks possibly died of carbon dioxide ...

This news release is available in German. The Bacillus cereus bacteria is one of the potential causes of food poisoning. Indeed, a recent study in Analytical and Bioanalytical Chemistry shows that this versatile pathogen produces 19 different variants of a poison that causes nausea and vomiting in human beings. This variety could explain why some cases are relatively benign and others can result in death. Across Europe, the number of food poisoning cases caused by the Bacillus species is on the rise. While unpleasant, infections resulting from B. cereus are usually ...

Our opponents always seem to be one step ahead. Although pest controllers now have numerous chemical preparations available, allowing them to take action against unwanted insects, the species targeted are developing a resistance against the different active substances at a rapid pace. Often a single change in the organisms' genetic material is enough to do this. This means that scientists know more than 500 pests all over the world currently able to resist a total of 300 different insecticides. Many disease-transmitting mosquitoes defy any attempts to control them just ...

The core circuits of quantum teleportation, which generate and detect quantum entanglement, have been successfully integrated into a photonic chip by an international team of scientists from the universities of Bristol, Tokyo, Southampton and NTT Device Technology Laboratories. These results pave the way to developing ultra-high-speed quantum computers and strengthening the security of communication. Qubits (quantum bits) are sensitive quantum versions of today's computer 0's and 1's (bits) and are the foundation of quantum computers. Photons are particles of light and ...

Penicillin has nearly eradicated rheumatic heart disease (RHD) in the United States. But 15 million people still suffer with the disease worldwide, and 1.4 million die each year, according to World Heart Federation. Access to penicillin can prevent deaths from RHD. Researchers from Case Western Reserve University, Makerere University and the Uganda Heart Institute at Mulago Hospital, a national referral hospital in Kampala, collaborated to learn about those obstacles to receive the medication and find ways to overcome them. The researchers heard from some Ugandans ...

The media is littered with celebrity trainers, bakers, nutritionists, even gardeners. But, one profession is always missing from the roster - the celebrity accountant. The reason is most likely due to the negative stereotypes propagated for centuries. However, this is no bad thing, according to researchers in Australia who suggest in the International Journal of Critical Accounting, that stock characters entrenched in popular culture provide professional stability. Frances Miley of the University of New South Wales and Andrew Read of the University of Canberra, Australia, ...

Damage to neural tissue is typically permanent and causes lasting disability in patients, but a new approach has recently been discovered that holds incredible potential to reconstruct neural tissue at high resolution in three dimensions. Research recently published in the Journal of Neural Engineering demonstrated a method for embedding scaffolding of patterned nanofibers within three-dimensional (3D) hydrogel structures, and it was shown that neurite outgrowth from neurons in the hydrogel followed the nanofiber scaffolding by tracking directly along the nanofibers, particularly ...
