'Defensive' action by influenza viruses demonstrated by Hebrew university researcher
...--- and before you know it, they've found a way to defend themselves and neutralize the anti-viral treatment. How, exactly, do the viruses do it? In an article published as the cover story in a recent issue of the journal Proteins, a Hebrew University of Jerusalem researcher, Prof. Isaiah (Shy) T. Arkin, h...Anti-cancer compound in vegetables found to block late-stage breast-cancer cell growth
...SUL is a potent inducer of enzyme systems that can defend against carcinogens," Singletary said. Such defense mechanisms are effective during the early stage of cancer.
