Answer: /b>. Ondansetron appears to have little potential for facilitating induction of therapeutic hypothermia.
no

Question: Are flavones from Erythrina falcata modulators of fear memory?
Answer: Our results demonstrate that vitexin, isovitexin and diosmetin-6-C-glucoside and flavonoidic fractions resulted in a significant retention of fear memory but did not prevent the extinction of fear memory. These results further substantiate that the treatment with pure flavonoids or flavanoid-rich fractions might represent potential therapeutic approaches for the treatment of neurocognitive disorders, improvement of memory acquisition and spontaneous recovery of fear.
yes

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.

yes
