question:
Question: Does the usage of overtube have a favorable effect on endoscopic submucosal dissection?
Answer: We conclude that using an overtube during an upper gastrointestinal ESD decreases the need for suction, favors the speed of dissection, and eases the comfort of the procedure.
answer:
yes


question:
Question: Is pyruvate dehydrogenase inactivity responsible for sepsis-induced insulin resistance?
Answer: Activation of pyruvate dehydrogenase with dichloroacetate does not ameliorate the impairment of whole-body, insulin-stimulated glucose uptake in septic humans or rats, or reverse the specific defect in insulin-mediated skeletal muscle glucose uptake by septic rats. Therefore, the decreased pyruvate dehydrogenase activity associated with sepsis does not appear to mediate sepsis-induced insulin resistance during insulin-stimulated glucose uptake at either the whole-body or tissue level.
answer:

no
