Features of replication suggest viruses have common themes, vulnerabilities
... Ahlquist's group and their collaborators made the first
three-dimensional maps of a viral replication complex using flock house virus, which, like all viruses, requires a host cell to make new genetic material and maintain the chain of infection. In the case of flock house virus, the Wisconsin group fo...

clinical study to show proof that chemicals in green tea can increase detoxification enzymes in humans, Chow said. There may be other mechanism in play by which green tea may protect against cancer development, but this is a good place to start....
High blood pressure, low energy -- a recipe for heart failure
