question:
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.
answer:
no

question:
Question: Does in vivo imaging of antileukemic drug asparaginase reveal a rapid macrophage mediated clearance from the bone marrow?
Answer: We show that asparaginase is rapidly cleared from the serum by liver, spleen and bone marrow-resident phagocytic cells. As a consequence of this efficient uptake and protease mediated degradation, particularly bone marrow resident macrophages may provide a protective niche to leukemic cells.
answer:
yes

question:
Question: Does chronic aerobic exercise improve blood pressure dipping status in African American nondippers?
Answer: This study suggests that the nondipping pattern of ambulatory BP can be improved by chronic AEXT in African American nondippers, regardless of a change in the 24-h average BP. This finding may be clinically important because of the target organ implication of nondipping nocturnal BP.
answer:
yes
