Example Input: Question: Does vagus nerve stimulation have antidepressant effects in the kainic acid model for temporal lobe epilepsy?
Answer: The KA rats displayed anhedonia which was significantly decreased by VNS, indicating that this neuromodulatory treatment could likewise diminish depressive symptoms in patients suffering from temporal lobe epilepsy and comorbid depression.
Example Output: yes

Example Input: 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.
Example Output: yes

Example Input: Question: Does remote ischemic preconditioning affect the incidence of acute kidney injury after elective abdominal aortic aneurysm repair?
Answer: RIPC did not reduce the risk of postoperative renal failure or myocardial injury in patients undergoing open AAA repair. The authors' results do not support the introduction of this technique to routine clinical practice.
Example Output:
no
