First large-scale survey of Chagas disease in the United States confirms that the 'silent killer' is a major public health challenge for the country

Thu, 13/04/2017 - 4:00pm
A study of almost 5,000 Latin American-born residents of Los Angeles County found that 1.24 percent tested positive for Chagas disease, a parasitic infection that can cause life-threatening heart damage if not treated early. Chagas disease is one of the leading causes of heart failure in Latin America.

Genetic link to susceptibility and resistance to inflammatory bowel disease

Thu, 13/04/2017 - 4:00pm
Inflammatory bowel disease (IBD), characterized by chronic relapsing inflammation of the gut, is a common problem in the industrialized world. However, how IBD develops remains unknown. There is currently no cure and treatment options are costly and limited to alleviating symptoms. A new study reveals that the Cd14 gene is a protective factor in experimental inflammatory bowel disease by enhancing the intestinal barrier function.

Study of Ebola patient traces disease progression and recovery

Thu, 13/04/2017 - 1:50pm
Analysis of daily gene activation in a patient with severe Ebola virus disease in 2015 found changes in antiviral and immune response genes that pinpointed key transition points in the response to infection. The changes included a marked decline in antiviral responses that correlated with clearance of virus from white blood cells.

Citizen scientists help identify shorebird extinction threat

Thu, 13/04/2017 - 1:50pm
A major contributor to the dramatic decline of migratory shorebird populations in Australia has been identified by researchers. Australian shorebirds were under threat due to the degradation and destruction of mudflats thousands of kilometers away in north-east Asia, they say.

Common drugs, uncommon risks? Higher rate of serious problems after short-term steroid use

Thu, 13/04/2017 - 1:50pm
People taking corticosteroids for short-term relief were more likely to break a bone, have a potentially dangerous blood clot or develop sepsis in the months after treatment, compared with similar adults who didn't use the drugs, a new study finds. Though only a small percentage of both groups went to the hospital for these serious health threats, the higher rates seen among people who took steroids are cause for caution, the researchers say.

Cognitive and psychosocial function of retired professional hockey players

Thu, 13/04/2017 - 1:24pm
Researchers have reported on the most comprehensive neuropsychological study of retired professional ice hockey players to date. They found that the alumni involved in the study, most of whom played in the NHL, were free from significant brain impairment on objective testing. Yet the players reported a high level of emotional, behavioural and cognitive challenges on questionnaires rating subjective complaints.

Moabosaurus discovered in Utah's 'gold mine'

Thu, 13/04/2017 - 1:24pm
Move over, honeybee and seagull: it's time to meet Moabosaurus utahensis, Utah's newly discovered dinosaur, whose past reveals even more about the state's long-term history. The bones of the 125-million-year-old dinosaur were extracted over the course of four decades from a quarry near Arches National Park.

Nanopores could map small changes in DNA that signal big shifts in cancer

Thu, 13/04/2017 - 12:47pm
Detecting cancer early, just as changes are beginning in DNA, could enhance diagnosis and treatment as well as further our understanding of the disease. A new study describes a method to detect, count and map tiny additions to DNA called methylations, which can be a warning sign of cancer, with unprecedented resolution.
