The rise of deadly insect sting allergies: Is there a cure?
Date: Aug-06-2013If you think summer insects are done setting their sights on ruining your outdoor gathering, think again. August's hot and dry climate is the perfect breeding ground for insects, especially yellow jackets. And for the millions of Americans allergic to insect stings, these late summer bugs can be deadly. According to a report released in the August issue of Annals of Allergy, Asthma & Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI), insect sting allergy is increasing, affecting five percent of the population...
New study explores the pathways that lead to jail time for women
Date: Aug-06-2013How do pathways to jail vary for females who are victims of specific types of trauma? New research published in Psychology of Women Quarterly, a SAGE journal, pinpoints the types of trauma such as caregiver violence, witnessing violence, and intimate partner violence, that lead to specific types of offending later in life and offers explanations based on real experiences. Researchers Dana DeHart, Shannon Lynch, Joanne Belknap, and Bonnie Green conducted life-history interviews with 115 female inmates from five U.S...
'Soft robotic' devices created using water-based gels
Date: Aug-06-2013Researchers from North Carolina State University have developed a new technique for creating devices out of a water-based hydrogel material that can be patterned, folded and used to manipulate objects. The technique holds promise for use in "soft robotics" and biomedical applications. "This work brings us one step closer to developing new soft robotics technologies that mimic biological systems and can work in aqueous environments," says Dr. Michael Dickey, an assistant professor of chemical and biomolecular engineering at NC State and co-author of a paper describing the work...
Seeking the right target to fight Alzheimer's disease
Date: Aug-06-2013The future is looking good for drugs designed to combat Alzheimer's disease. EPFL scientists have unveiled how two classes of drug compounds currently in clinical trials work to fight the disease. Their research suggests that these compounds target the disease-causing peptides with high precision and with minimal side-effects. At the same time, the scientists offer a molecular explanation for early-onset hereditary forms of Alzheimer's, which can strike as early as thirty years of age...
Moderate kidney disease costs medicare tens of billions of dollars each year
Date: Aug-06-2013Even early stages of kidney disease come with steep medical costs, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The study found that expenses related to moderate chronic kidney disease (CKD) cost Medicare tens of billions of dollars each year. Approximately 60 million people globally have CKD. Most of the costs of CKD are thought to arise when the disease progresses to kidney failure, also known as stage 5 CKD...
Feeling left out can lead to risky financial decisions, research finds
Date: Aug-06-2013People who feel isolated are more inclined to make risker financial decisions for bigger payoffs, according to new research presented at the American Psychological Association's 121st Annual Convention...
Simple ultrasound treatment may help protect the kidneys
Date: Aug-06-2013Ultrasound treatments may prevent acute kidney injury that commonly arises after major surgery, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The findings suggest that this simple and noninvasive therapy may be an effective precaution for patients at risk. Acute kidney injury, an abrupt decline in kidney function, is an increasingly prevalent and potentially serious condition in hospitalized patients...
Fly study finds 2 new drivers of RNA editing
Date: Aug-06-2013RNA editing gives organisms a way to adapt the instructions that their DNA provides for making proteins. Few people would have described RNA editing as a simple process, but a new paper in Nature Communications demonstrates the process as more complex and difficult to predict than previously assumed. The study, done in living fruit flies, discovered two new mechanisms that govern editing in a key neurodevelopmental gene...
2 dimensions of value: dopamine neurons represent reward but not aversiveness
Date: Aug-06-2013To make decisions, we need to estimate the value of sensory stimuli and motor actions, their "goodness" and "badness." We can imagine that good and bad are two ends of a single continuum, or dimension, of value. This would be analogous to the single dimension of light intensity, which ranges from dark on one end to bright light on the other, with many shades of gray in between...
McMaster researchers find home of best stem cells for bone marrow transplants
Date: Aug-06-2013McMaster University researchers have revealed the location of human blood stem cells that may improve bone marrow transplants. The best stem cells are at the ends of the bone. It is hoped this discovery will lead to lowering the amount of bone marrow needed for a donation while increasing regeneration and lessening rejection in the recipient patients, says principal investigator Mick Bhatia, professor and scientific director of the McMaster Stem Cell and Cancer Research Institute...
