Innovative smallpox vaccine research study to be conducted at Case Medical Center

... against smallpox. Smallpox is a contagious and sometimes fatal infectious disease characterized by raised bumps that appear on the face and body of an infected person. There is no specific treatment for smallpox disease, and the only prevention is vaccination. The World Health Organization declared the dis...

Simulations unravel outer membrane transport mechanism

...fore and after activation,” Tajkhorshid said. “And sometimes the labeling agent that they use diffuses into the beta-barrel and labels the inside: You don’t know whether what you have labeled is happening inside or outside.” U. of I. researchers simulated the interaction of part of the inner membrane protein...

Genetic factors are linked to fever following smallpox vaccination

...e virus particles, as in the smallpox vaccine, can sometimes cause reactions that range from fatigue to serious illness. In recent studies testing the safety and potency of stored smallpox vaccine, which uses live vaccinia virus, some individuals developed fevers. The authors of the study, Samuel L. Stan...

Helping chlorine-eating bacteria clean up toxic waste

...chardson explained that in the field "the bacteria sometimes start and then stop. We might improve conditions for the organisms." For example, she said, it has been found that Dehalococcoides needs vitamin B-12, so the vitamin is added to cultures that are injected into cleanup sites. The bacterium also grows ...

Understanding why C. difficile causes disease -- it's hungry

... might help them find a new treatment for what can sometimes be a very difficult disease to treat. "The genes responsible for toxin production only seem to be expressed during periods of nutrient deprivation. This is consistent with the view that most disease-causing bacteria express their pathogenicity whe...
