PROBLEM: Question: Does pharmacological preconditioning using intraportal infusion of L-arginine protect against hepatic ischemia reperfusion injury?
Answer: Pharmacological preconditioning with intraportal L-arginine provided protection against hepatic I/RI in early phases of the reperfusion period. The mechanisms underlying the protective effect may include preservation of the mitochondrial structure and inhibition of caspase-3 activity.

SOLUTION: yes

PROBLEM: Question: Do rates of labor induction and primary cesarean delivery correlate with rates of adverse neonatal outcome in level I hospitals?
