[Q]: Question: Does fK778 attenuate cytomegalovirus-enhanced vein graft intimal hyperplasia in a rat model?

[Q]: Question: Do anti-oxidants prevent bile acid-induced cell death in rat hepatocytes?
Answer: In hepatocytes, bile acid-induced toxicity is not prevented by scavengers of oxidative stress. The beneficial effects observed in patients might be because of the contribution of ROS and cytokines rather than bile acid-mediated oxidative stress. However, the use of specific Src kinase inhibitors might be a useful tool to prevent bile acid-induced injury in liver diseases.
[A]:
no
