In low-income urban neighborhoods the rates of diabetes, hypertension, heart disease and stroke are much higher
Date: Nov-07-2013There is more to the cost of living in a food desert than higher prices for the few fruits and vegetables sold nearby, according to a study by an Indiana University-Purdue University Indianapolis researcher and the Marion County Public Health Department. The study, discussed during the American Public Health Association's annual meeting in Boston, examined the health impact of developing a grocery store in a low-income urban neighborhood on the east side of Indianapolis...
The development and treatment of antisocial behavior
Date: Nov-07-2013Using the hi-tech tools of a new field called neurogenetics and a few simple questions for parents, a University of Michigan researcher is beginning to understand which boys are simply being boys and which may be headed for trouble. "When young children lie or cheat or steal, parents naturally wonder if they'll grow out of it," says Luke Hyde, a U-M psychologist who is studying the development and treatment of antisocial behavior...
Playing out medical experiences can help chronically ill children, as well as their siblings, express fears and foster hope for recovery
Date: Nov-07-2013New research finds that chronically ill children celebrate a successful recovery. It's through their imaginative play with medically themed toys. Laura Nabors, an associate professor of human services in the University of Cincinnati College of Education, Criminal Justice, and Human Services (CECH), presented new research at the American Public Health Association's (APHA) 141st Annual Meeting and Expo in Boston. The project primarily focused on chronically ill children and their siblings who were staying at the Ronald McDonald House in Cincinnati...
Web-based, at-home interventions can help mothers address behaviors known to protect against childhood obesity
Date: Nov-07-2013Never underestimate the power of Mom when it comes to influencing children's health. University of Cincinnati research explains how motherly influence could be even more effective when supported by Web-based parent education programs. Adam Knowlden, a former doctoral student at UC and current assistant professor in the University of Alabama's Health Science Department, hopes his research can better prepare moms to keep their kids from joining the rising ranks of America's obese children...
New insights into brain neuronal networks
Date: Nov-07-2013A paper published in a special edition of the journal Science proposes a novel understanding of brain architecture using a network representation of connections within the primate cortex. Zoltán Toroczkai, professor of physics at the University of Notre Dame and co-director of the Interdisciplinary Center for Network Science and Applications, is a co-author of the paper "Cortical High-Density Counterstream Architectures...
Surgery as 'last resort' for vomiting babies
Date: Nov-07-2013Most babies and young children spit up after feeding, but it can sometimes be more than just infant reflux. However, doctors from Seattle Children's Hospital question whether surgeons are too quick to intervene - especially for infants under 2 months of age. Reflux is no cause for alarm in itself if the infant is thriving and gaining weight. But if the baby spits up green or yellow liquid, blood, or a mixture that looks like coffee grounds, it may be a sign of gastroesophageal reflux disease (GERD)...
Genes definitely linked to brain aging
Date: Nov-07-2013For the first time in a large study sample, the decline in brain function in normal aging is conclusively shown to be influenced by genes, say researchers from the Texas Biomedical Research Institute in San Antonio and Yale University. "Identification of genes associated with brain aging should improve our understanding of the biological processes that govern normal age-related decline," said John Blangero, Ph.D., a Texas Biomed geneticist and the senior author of the paper...
New membrane pores with DNA nanotechnology
Date: Nov-07-2013A new way to build membrane-crossing pores, using Lego-like DNA building blocks, has been developed by scientists at UCL, in collaboration with colleagues at the University of Cambridge and the University of Southampton. The approach provides a simple and low cost tool for synthetic biology and the technique has potential applications in diagnostic devices and drug discovery. The research is featured in the current issue of the journal Angewandte Chemie...
Gene sequencing reveals mutations in estrogen receptor responsible for breast cancer treatment resistance
Date: Nov-07-2013Researchers at the University of Michigan Comprehensive Cancer Center have identified a type of mutation that develops after breast cancer patients take anti-estrogen therapies. The mutations explain one reason why patients often become resistant to this therapy. The study appears online in Nature Genetics. The discovery stems from a program at the U-M Comprehensive Cancer Center called Mi-ONCOSEQ in which patients with advanced cancer have their DNA and RNA sequenced to identify all types of genetic mutations that could play a role in the cancer...
Structure of key complex in the immune system mapped
Date: Nov-07-2013Leicester scientists have mapped the "bouquet-like" structure of a key part of the body's immune system responsible for neutralising bacteria and viruses. A team from the University of Leicester's Departments of Infection, Immunity, and Inflammation and Biochemistry led a project which has mapped the structure of complement component C1 - a large complex of the immune system. The C1 complex is a protein which is responsible for spotting foreign agents in the blood which can cause disease - known as pathogens...
