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.
no

Question: Does implementing goal-directed protocols reduce length of stay after cardiac surgery?
Answer: A milestone-driven pathway supported by team rounding was associated with decreased lengths of CVICU and hospital stay. However, tracking patient trajectories by milestones suggests a more complex relationship than anticipated and presents new opportunities for SREBP implementation and research.
yes

Question: Is clinical success of intrauterine insemination cycles affected by the sperm preparation time?
