Exposure to pyrethroid insecticides linked to mortality

(HealthDay)—Environmental exposure to pyrethroid insecticides is associated with an increased risk for all-cause and cardiovascular disease mortality, according to a study published online Dec. 30 in JAMA Internal Medicine. Wei Bao, M.D., Ph.D., from the University of Iowa in Iowa City, and colleagues examined the correlation of pyrethroid exposure with all-cause and cause-specific mortality using data from 2,116 adults aged […]

Identification of a key protein linked to ageing

Ageing is a dramatic public health issue in the face of the current demographic changes: the proportion of 60 and over in the world’s population will almost double by 2050. In this context, a new discovery has just broadened scientific knowledge. Researchers from the Developmental and Stem Cell Biology Department at the Institut Pasteur shed light on the mechanisms of […]

Schizophrenia risk gene linked to cognitive deficits in mice

Researchers have discovered in mice how one of the few genes definitively linked to schizophrenia, called SETD1A, likely confers risk for the illness. Mice genetically engineered to lack a functioning version of the enzyme-coding gene showed abnormalities in working memory, mimicking those commonly seen in schizophrenia patients. Restoring the gene’s function corrected the working memory deficit. Counteracting the gene’s deficiencies […]

Concussions linked to erectile dysfunction in former NFL players

Former professional football players who have experienced concussion symptoms, including loss of consciousness, disorientation or nausea after a head injury, are more likely to report low testosterone and erectile dysfunction (ED), according to research published Aug. 26 in JAMA Neurology. The research—based on a survey of more than 3,400 former NFL players representing the largest study cohort of former professional […]

Eating more plant-based foods may be linked to better heart health

Eating mostly plant-based foods and fewer animal-based foods may be linked to better heart health and a lower risk of dying from a heart attack, stroke or other cardiovascular disease according to new research published in the Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association. “While you don’t have to give […]

Microvascular disease anywhere in the body may be linked to higher risk of leg amputations

Microvascular disease is independently associated with a higher risk of leg amputation compared to people without the disease, according to new research in the American Heart Association’s journal Circulation. The study, funded by the American Heart Association Strategically Focused Research Network in Vascular Disease and the U.S. Department of Veterans Affairs, examined amputation risk among people with microvascular disease or […]

Rapid spread of a meningitis bacteria linked to hypermutable sequences helping avoidance of the immune system

An enhanced potential to avoid the human immune system has been found in recent serogroup W isolates of Neisseria meningitidis by University of Leicester researchers, which may explain in part why the strain spread so rapidly among young people in 2013. The study, published last week in the Journal of Infectious Diseases, saw researchers from Leicester, the University of Nottingham […]

Genetic marker linked to increased risk of diabetic peripheral neuropathy

Researchers from Joslin Diabetes Center, using a genome-wide association study, have identified a genetic factor linked to the development of diabetic peripheral neuropathy. This finding suggests a new target for preventive therapies. The research has been published online and will appear in the August print issue of Diabetes. While neuropathy, which causes pain or numbness in the legs and an […]

Circadian clock and fat metabolism linked through newly discovered mechanism

The enzyme Nocturnin, which governs daily tasks such as fat metabolism and energy usage, works in an entirely different way than previously thought, reported a team of researchers at Princeton University. The newly discovered mechanism reveals the molecular link between the enzyme’s daily fluctuations and its energy-regulating role in the body, according to a study published this week in Nature […]
