These impacts are further minimized with daily composites created through the combination of individual images. While high ...

Old drug shows new promise for Huntington's Disease

... given approximately 1 milligram of Clioquinol per day in water. After eight weeks of treatment, they had accumulated four times less toxic protein in their brains than control mice given water alone. The experimental animals lived 20 percent longer than the control animals, did better on tests of motor ...

Researcher at UGA College of Veterinary Medicine identifies new way of combating viral diseases

Four seemingly unrelated viral diseases may some day be defeated by a single treatment, according to a recent collaborative study involving researchers at the University of Georgia's College of Veterinary Medicine. Their study focuses on viruses responsible for HIV, measles, Ebola and Marburg and incl...

Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

...er understanding of how photolyase works could one day lead to drugs that help repair UV damage in human DNA. In the online edition of the Proceedings of the National Academy of Sciences, Dongping Zhong and his colleagues report experimental evidence of what scientists have long suspected -- that visibl...

Does manganese inhaled from the shower represent a public health threat?

...time," Spangler said. "Regulatory agencies may one day need to rethink existing drinking water standards for manganese." The addition of manganese to gasoline as an anti-knock agent may also be a threat, the researchers said. "The manganese, as it settles from car exhaust onto streets and highways, may...

Study findings offer potential new targets for antibiotics

...ets for antibiotics. These sites are what may one day give pharmaceutical companies an edge in creating new antibiotics in order to keep ahead of bacteria's clever way of developing resistance to antibiotics. "Now that we know these other sites exist and that they could be potential targets for antibio...
