question:
Question: Is epithelium-dependent bronchodilatory activity preserved in pig bronchioles after normothermic cardiopulmonary bypass?
Answer: Normothermic cardiopulmonary bypass does not result in epithelial dysfunction in pigs. Epithelium-dependent and epithelium-independent bronchodilators may be equally effective before and after cardiopulmonary bypass.
answer:
yes

question:
Question: Does prescription consisting of Vitamin C and Baicalin inhibit tumor growth by enhancing the antioxidant capacity in vivo?
Answer: PVB shows better antitumor effect than Vc and baicalin used alone, and it can significantly enhance the immunity and antioxidant capacity of the mice.
answer:
yes

question:
Question: Does tissue plasminogen activator promote postischemic neutrophil recruitment via its proteolytic and nonproteolytic properties?
Answer: Endogenously released tPA promotes neutrophil transmigration to reperfused tissue via proteolytic activation of plasmin and gelatinases. As a consequence, tPA on transmigrating neutrophils disrupts endothelial junctions allowing circulating tPA to extravasate to the perivascular tissue, which, in turn, amplifies neutrophil recruitment through the activation of mast cells and release of lipid mediators.
answer:
yes
