Answer: There is a high risk of potential traumatic flap problems after LASIK and it is not recommended in army service.

SOLUTION: no

PROBLEM: Question: Does apelin-13 protect the heart against ischemia-reperfusion injury through the RISK-GSK-3β-mPTP pathway?
Answer: The protective mechanism of apelin-13 might be that inactivation of GSK-3β could inhibit the opening of mPTP by activating PI3K/Akt and ERK1/2 involved in the reperfusion injury salvage kinase (RISK) pathway.

SOLUTION: yes

PROBLEM: Question: Does 18β-Glycyrrhetinic acid protect against methotrexate-induced kidney injury by up-regulating the Nrf2/ARE/HO-1 pathway and endogenous antioxidants?
Answer: These results indicate that 18β-GA has a protective effect on MTX-induced nephrotoxicity with possible mechanisms of attenuating oxidative stress and inflammation through up-regulating the Nrf2/ARE signaling. These findings make 18β-GA candidate as a potent agent in preventing MTX-induced kidney injury.

SOLUTION:
yes
