Question: Does catecholamine release induce elevation in plasma lactate levels in patients undergoing adrenalectomy for pheochromocytoma?
Answer: Catecholamine release caused by surgical manipulation may be a possible cause of intraoperative transient lactic acidosis, and it should be considered as a differential diagnosis of intraoperative lactic acidosis. Intraoperative peak plasma lactate level was correlated with preoperative epinephrine-releasing activity.

Ex Output:
yes


Ex Input:
Question: Does tobacco smoking differently influence cell types of the innate and adaptive immune system-indications from CpG site methylation?
Answer: Studying cell type-specific methylation changes provides helpful information regarding the biological relevance of epigenetic modifications. Here, we could show that smoking differently affects both cells of the innate and adaptive immune systems.

Ex Output:

yes
