South Africa has one of the world?s highest rates of HIV infection. New research, led by Brown University professor Mark Lurie, shows that the movement of workers between urban and rural areas played a key role in the spread of the epidemic. Results are published in AIDS.
Genetic testing for eye disease is providing vital information about complex retinal diseases, especially when used to confirm a clinician?s diagnosis, according to a newly published study of such tests that were conducted over a five-year period.
A new type of protein discovered by Queen?s University researchers may be useful in developing treatments for antibiotic-resistant bacteria, such as those that cause food poisoning and typhoid.
A CNRS team headed by Philippe Froguel (CNRS, University of Lille 2, Pasteur Institute, Imperial College London) and Rob Sladek (McGill University, Montreal, Canada) in a French-British-Canadian collaboration that accounts for about 70 percent of the genetic risk for patients with type two diabetes.
Expenditures for the uninsured in Maryland totaled $1.47 billion in FY2002, according to an analysis conducted by researchers at the Johns Hopkins Bloomberg School of Public Health.
Johns Hopkins brain scientists have hit on how and why some powerful drugs used for treating mental illnesses cause patients to gain so much weight that they often develop life-threatening complications such as diabetes and heart disease.
The Scripps Research team, led by neuroscientists Manuel Sanchez-Alavez and Tamas Bartfai, discovered that mice genetically altered to lack a molecule known as the EP3 receptor tend to be more active during their normal sleep cycle and to eat more. In the study, this led to weight increases of up to 30 percent relative to mice with the receptors.
Bioengineers and public health researchers have developed a novel spray drying method for preserving and delivering the most common tuberculosis (TB) vaccine. The low-cost and scaleable technique offers several potential advantages over conventional freezing procedures, such as greater stability at room temperature and use in needle-free delivery.
A new study published in the February 2007 issue of the American Journal of Medical Genetics reveals that individuals with genetic conditions are twice as likely to report having been denied health insurance than individuals with other chronic illnesses.
A complex molecule and snake venom may provide researchers with a more reliable method of diagnosing human diseases and developing new drugs.
