Scientists at the Virginia Bioinformatics Institute and Duke University Medical Center have pinpointed a fungal gene that appears to play an important role in the development and virulence of Alternaria brassicicola, a destructive fungal pathogen that results in considerable leaf loss in many economically important crops worldwide, including canola, cabbage and broccoli.
Transplanted neural stem cells hold promise for reducing the destruction of dopaminergic cells that occurs in Parkinson’s disease and for replacing cells lost to the disease, scientists say.
Scientists have discovered that mutations in a gene known as SOS1 account for many cases of Noonan syndrome (NS), a common childhood genetic disorder which occurs in one in 1,000-2,500 live births. NS is characterized by short stature, facial abnormalities and learning disabilities, as well as heart problems and predisposition to leukemia.
Dartmouth researchers report that three different steroid hormones all show similar responses to arsenic, suggesting a broader effect and a common mechanism of arsenic on how these hormones function.
A database developed by a research team based at Massachusetts General Hospital — the first comprehensive list of emergency departments (EDs) across the country — shows that one-third of all EDs care for less than one patient each hour, on average. The database is the first step in a process that may lead to the development of an ED classification system, similar to what currently exists for trauma centers.
Bill Clinton, former President of USA, says India is the new epicenter of the global pandemic of HIV. He commented this with British interviewers on the World AIDS Day.
An 11 year study conducted by the Queensland Institute of Medical Research has concluded that eating leafy greens such as spinach may be as important as wearing sunscreen, protective clothing and a hat in the prevention of skin cancer, highlighting the importance of eating a healthy, well-balanced diet.
A sugar molecule present on embryonic stem cells also has been found on the surface of a type of adult stem cell, a discovery that may help researchers isolate and purify adult stem cells for use in therapies aimed at bone healing, tendon repair and cartilage regeneration, researchers at UT Southwestern Medical Center report.
Researchers in the Oregon Health & Science University Digestive Health Center are first to report that screening people with chronic heartburn or pre-cancer of the esophagus in an office setting using a “skinny scope” is as accurate, less expensive and less risky than a traditional sedated screening in a procedure room — and patients prefer it. The findings are published online and in print in this month’s issue of the American Journal of Gastroenterology.
Taking your child to a pediatric subspecialist may mean a big-time travel commitment, researchers at the University of North Carolina at Chapel Hill’s School of Public Health have found.
