Definition: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Input: Question: Does landiolol , an ultra short-acting beta1-adrenoceptor antagonist , alter the minimum alveolar anesthetic concentration of isoflurane in a swine model?
Answer: Landiolol does not alter the antinociceptive effect of isoflurane. This result, combined with that from our previous work, also suggests that landiolol does not influence the anesthetic potency of inhaled anesthetics.
Output:
no
