Answer: Treatment failure with anti-depressant medication does not predict acute remission status with ECT for nonpsychotically depressed patients.
Example Output: no

Example Input: Question: Does eHD3-dependent endosome pathway regulate cardiac membrane excitability and physiology?
Answer: These data provide new insight into the critical role of endosome-based pathways in membrane protein targeting and cardiac physiology. EHD3 is a critical component of protein trafficking in heart and is essential for the proper membrane targeting of select cellular proteins that maintain excitability.
Example Output: yes

Example Input: Question: Does clostridium difficile Infection be Associated With Lower Inpatient Mortality When Managed by GI Surgeons?
