Gene therapy study takes aim at prostate cancer

...ctivated adenovirus (related to viruses that cause respiratory infections) to the RTVP-1 gene. As the virus infects the tumor cells, it will introduce the gene into the cells as well. (RTVP stands for related to testes-specific, vespid and pathogenesis proteins.) The RTVP-1 gene was isolated in the laboratory of...

UGA scientists unravel 'molecular inch-worm' structure of walking-pneumonia bacterium

...ause it is involved in cell division, adherence to respiratory tissues and a little-understood mechanism of propulsion called "gliding motility." Bacteria can move in a variety of ways, including the use of flagella to "swim." But since M. pneumoniae lack flagella, they "glide," a method of movement that has b...

Mayo Clinic study suggests that a central nervous system viral infection can lead to memory deficits

...ommon cold; enteroviruses, a virus associated with respiratory and gastrointestinal ailments; encephalitis, inflammation of the brain; myocarditis, inflammation of heart muscle; and meningitis. Other viruses in this family include those that cause foot-and-mouth disease, polio and hepatitis A. Researchers wer...

High hourly air pollution levels more than double stroke risk

...nd Environmental Medicine. Currently, the risk of respiratory and cardiovascular problems tends to be linked to the average daily amount of air pollution, rather than variations in hourly levels. The researchers assessed data on stroke deaths in people aged 65 years and older, occurring between January 1990 an...

NASA study: Alaskan fires affected Houston air quality in 2004

...tion. Besides posing a health risk for people with respiratory problems, ground-level ozone has also been linked to increased rates of asthma among children, and it can destroy plants and reduce crop yields. Federal regulators have given the Houston-Galveston region until 2007 to comply with federal air-quality ...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

...threats such as H5N1 avian influenza. "For some respiratory viruses, you've either cleared the infection at that point or succumbed to the infection," Tripp said. "What we've developed is the next generation of diagnostic testing." ...

Scientists find mutations that let bird flu adapt to humans

... gain easy access to cells, typically in the human respiratory system. The change is thought to occur when human patients are exposed at the same time to a human flu virus and an avian flu virus. Most viruses, including influenza, readily swap genes with one another. In the new study, conducted by an intern...

Faster, more accurate tuberculosis test developed

... authors collected 3,760 sputum--saliva mixed with respiratory discharge--in order to complete sensitivity and susceptibility studies of the MODS test. All samples were decontaminated and then used for parallel MODS testing, as well as for two current gold standard TB tests-- the Lowenstein-Jensen culture and au...
