Single molecular switch may contribute to major aging-related diseases

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.

Mental health providers not well prepared to care for military veterans, study finds

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.

UT Arlington team says non-genetic changes can help parents or offspring, not both

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.

In preschoolers, office test overestimates eye's ability to change focus, reports Optometry and Vision Science

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 Optometry and Vision Science, official journal of the American Academy of Optometry.

Innovative approach to treating pancreatic cancer combines chemo- and immuno-therapy

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.

High blood pressure puts one in four Nigerians at risk, study says

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.

Single-dose, needle-free Ebola vaccine provides long-term protection in macaques

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.

Research links tobacco smoke and roadway air pollution with childhood obesity

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.

Inhabit(ants) of New York City: High diversity underfoot in urban environments

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.

Scientists unveil new targets, test to develop treatments for memory disorder

JUPITER, FL, November 12, 2014 - In a pair of related studies, scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified a number of new therapeutic targets for memory disorders and have developed a new screening test to uncover compounds that may one day work against those disorders.

A previously unrecognized flame retardant found in Americans for the first time

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.

New 'care bundle' achieves drop in death rate for emergency abdominal surgery patients

Four UK hospitals have achieved a huge reduction in the number of patients dying following emergency abdominal surgery, after adopting a 'care bundle' devised by patient safety specialists.

The care bundle was developed at the Royal Surrey County Hospital in Guildford and implemented in the Royal United Hospital Bath, Torbay Hospital and the Royal Devon and Exeter Hospital. The results were analysed by academics at the University of Bradford

Scientists discover new properties of microbes that cause common eye infection

BOSTON (Nov. 12, 2014) - Scientists from Massachusetts Eye and Ear/Harvard Medical School Department of Ophthalmology have used the power of new genomic technology to discover that microbes that commonly infect the eye have special, previously unknown properties. These properties are predicted to allow the bacterium -- Streptococcus pneumoniae -- to specifically stick to the surface of the eye, grow, and cause damage and inflammation.

Oral cancer-causing HPV may spread through oral and genital routes

Oral human papillomavirus (HPV) infections were more common among men who had female partners with oral and/or genital HPV infection, suggesting that the transmission of HPV occurs via oral-oral and oral-genital routes, according to a McGill University study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Many microbiome studies flawed by contamination

Many published microbiome studies are likely to have been contaminated and may incorrectly report the presence of microorganisms unintentionally introduced from the laboratory environment, says a study published in the open access journal BMC Biology. The findings could explain why unexpected bacteria have been previously identified in clinical samples and suggests that studies may have prematurely proposed links to disease.
