Input: Consider Input: Question: Does resident participation affect surgical outcomes , despite introduction of new techniques?
Answer: In the context of this single surgical operation, resident participation does not substantially affect major complication rates. The common residency training paradigm provides clinical experience and supervision without necessarily impacting patient safety. Analysis of additional operations in different settings will be necessary.

Output: no


Input: Consider Input: Question: Are fatty acid-amino acid conjugates essential for systemic activation of salicylic acid-induced protein kinase and accumulation of jasmonic acid in Nicotiana attenuata?
Answer: Our results reveal that N. attenuata specifically recognizes herbivore-derived FACs in damaged leaves and rapidly send out a long-distance signal to phylotactically connected leaves to activate MAPK and JA signaling, and we propose that FACs that penetrated into wounds rapidly induce the production of another long-distance signal(s) which travels to all systemic leaves and activates TPI defense.

Output: yes


Input: Consider Input: Question: Does minimal hepatic encephalopathy impair health-related quality of life in patients with cirrhosis : a prospective study?
