New research out of St. Michael's Hospital has found that multiple factors independently predict what makes youth more likely to make repeat suicide-related behaviour. The study, led by Dr. Anne Rhodes, a research scientist at the hospital's Suicide Studies Research Unit, looked at whether factors such as permanent removal from the parental home by the courts due to maltreatment, neighbourhood size or income, gender, severity of first visit to an emergency department, age or having a mental disorder made youth significantly more likely to repeat suicide-related behavior. "We ...

Washington–A new study from The Pew Charitable Trusts, "Making Hard Choices: Navigating the Economic Shock of Unemployment," examines how American families cope with unexpected financial setbacks and how those periods of economic uncertainty draw down financial resources. The report studies families across race and income levels, revealing different experiences resulting from unemployment and the difficult choices many of them face. Building upon Pew's prior research, this report underscores the significance of financial resources other than income, particularly savings ...

Researchers at Moffitt Cancer Center have determined that the overexpression of microRNA-155 (miR-155), a short, single strand of ribonucleic acid encoded by the miR-155 host gene, promotes the growth of blood vessels in tumors, tumor inflammation, and metastasis. As a therapeutic target, miR-155 could potentially provide a new avenue of treatment when targeted with drugs to suppress its activity. The study was published in an online issue of Oncogene in January. MiR-155, which plays an important role in various physiological and pathological processes, is considered ...

JUPITER, FL, April 3, 2013 – Human diseases caused by misfolded proteins known as prions are some of most rare yet terrifying on the planet—incurable with disturbing symptoms that include dementia, personality shifts, hallucinations and coordination problems. The most well-known of these is Creutzfeldt-Jakob disease, which can be described as the naturally occurring human equivalent of mad cow disease. Now, scientists from the Florida campus of The Scripps Research Institute (TSRI) have for the first time identified a pair of drugs already approved for human use that ...

PubMed Central may draw readership away from biomedical journal sites, with this effect increasing over time. This finding—that PubMed Central directly competes with biomedical publishers—was published online in The FASEB Journal. In the study, Phillip M. Davis shows that as articles are deposited in PubMed Central, they draw readership away from the scientific journal even when journals themselves are providing free access to the articles. Over time, this may weaken the ability of journals to build communities of interest around research papers, impede the communication ...

University of Notre Dame researchers have successfully created three-dimensional anatomical models from CT scans using 3-D printing technology, a process that holds promise for medical professionals and their patients. A paper by the researchers, "3D Printing of Preclinical X-ray Computed Tomographic Data Sets," was published in the Journal of Visualized Experiments this week. The strategy was initiated last spring by then-freshman Evan Doney, a Glynn Family Honors student in the laboratory of W. Matthew Leevy, research assistant professor at the Notre Dame Integrated ...

Coral Gables, Fla. – April 2, 2013 -- New research from the University of Miami School of Business Administration offers marketers a strategy for how best to structure free giveaways with products in order to maximize sales. The study, just published in the Journal of Marketing, shows that when a product that triggers more emotion (called affect), such as makeup, is offered with a free gift, shoppers are more likely to buy that product if the type of gift is unknown than if the type of gift is revealed. So much so, that in this case, it can up to double the purchase ...

Bottom-up synthesis of nanowires through metal-catalyzed vapor phase epitaxy is a very attractive process to generate high-quality nanowires thus providing an additional degree of freedom in design of innovative devices that extend beyond what is achievable with the current technologies. In this nano-fabrication process, nanowires grow through the condensation of atoms released from a molecular vapor (called precursors) at the surface of metallic nano-droplets. Gold is broadly used to form these nano-droplets. This self-assembly of nanowires takes place spontaneously ...

Could drug addiction treatment of the future be as simple as an on/off switch in the brain? A study in rats has found that stimulating a key part of the brain reduces compulsive cocaine-seeking and suggests the possibility of changing addictive behavior generally. The study, published in Nature, was conducted by scientists at the Intramural Research Program of the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, and the University of California, San Francisco. "This exciting study offers a new direction of research for the treatment ...

Scientists have decoded the genome of the western painted turtle, one of the most abundant turtles on Earth, finding clues to their longevity and ability to survive without oxygen during long winters spent hibernating in ice-covered ponds. Understanding the natural mechanisms turtles use to protect the heart and brain from oxygen deprivation may one day improve treatments for heart attacks or strokes, the researchers say. Both can lead to severe disability or death within minutes in patients deprived of oxygen. The research team includes scientists at Washington University ...

Consumer-directed health plans (CDHPs) offer low premiums but high deductibles on the premise that patients who are faced with deductibles of $1,000 or more for individual coverage (or twice that for family coverage) will shop around for the best price for the health care. In practice, however, that's not the case, according to a new study by the USC Schaeffer Center for Health Policy and Economics and the RAND Corporation. Examining the consumer decisions with and without CDHPs when receiving nine common outpatient services (such as office visits, chest x-rays and ...

Researchers at the University of Montreal have found that the glycated hemoglobin levels of children with type 1 diabetes followed at its affiliated Sainte-Justine Mother and Child University Hospital (CHU Sainte-Justine) is correlated linearly and negatively with household income. Glycated hemoglobin is the binding of sugar to blood molecules – over time, high blood sugar levels lead to high levels of glycated hemoglobin, which means that it can be used to assess whether a patient properly controls his or her blood glucose level. "Our study highlights a marked disparity ...

DALLAS – April 4, 2013 – Physician-researchers at UT Southwestern Medical Center have identified a vulnerability of certain lung-cancer cells – a specific genetic weakness that can be exploited for new therapies. Although researchers have long known that mutant versions of the KRAS gene drive tumor formation and are key to cell survival in non-small cell lung cancer, the blocking of activated KRAS has proven difficult. For years, investigations have explored stopping lung cancer at this junction, which also would have an impact on many other cancers. KRAS mutations, for ...
