Study identifies risk factors for spread of respiratory infections in hospitals

...se treatments may propel infectious air from these patients farther than without masks or ventilation. Alternatively, they may generate more infectious aerosols. "There is a gap in the knowledge of how oxygen and ventilation therapy may promote the spread of infection. Future research should include inves...

Genes and biomarkers that allow doctors to choose the right therapy for the right patient

Carnegie Mellon University research shows how sensory-deprived brain compensates

... use" therapy is already applied in the clinic for patients with motor deficits. For example, a patient who suffers a brain injury is made to use a poorly performing arm with the expectation that the brain may be plastic enough to assist that arm in recovering motion. "We think that our well-designed ...

Selective marker found to indicate aggressive form of breast cancer

...ke nestin would enable clinicians to monitor these patients through frequent tests of a biomarker and, in doing so, detect the cancer before it has a chance to come back." Basal epithelial tumors lack important molecular targets such as the estrogen receptor, progesterone receptor and Her2. This not only ...

Gene therapy for blindness clears hurdle in mice

...al sight. The rate of progression varies, but most patients are blind by 40. UF Genetics Institute researchers engineered the interfering RNA into a virus, which in turn was injected below the retinas in more than a dozen normal mice. Analysis showed the technique reduced the amount of rhodopsin by about 6...

In mice, gallium treatment blocked both chronic and acute infections caused by this bacterium. The idea of using gallium as a substitute for iron was developed by a group led by Bradley Britigan, a res...

Xylitol reduces risk of cavities

...take of xylitol is recommended as a supplement for patients at high risk for tooth decay. Xylitol products that actively stimulate the secretion of saliva should be the first choice, such as chewing gum. About 6 g of xylitol per day is needed to counteract the production of acid and thereby reduce the r...
