Input: Consider Input: Question: Is s100A8/A9 involved in host defense against murine urinary tract infection?
Answer: We show that despite high S100A8/A9 expression in bladder and kidney tissue upon UTI, S100A8/A9 does not contribute to an effective host response against E. Coli in the urinary tract system.

Output: no


Input: Consider Input: Question: Does remote ischemic preconditioning affect the incidence of acute kidney injury after elective abdominal aortic aneurysm repair?

Output: no


Input: Consider Input: Question: Does targeting oliguria reversal in perioperative restrictive fluid management influence the occurrence of renal dysfunction : A systematic review and meta-analysis?

Output: no
