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.

Question: Do feasibility of using tissue Doppler velocities in stress echo during upright bicycle exercise?
Answer: Tissue velocities decreased from base to apex. Mean difference between the raters was-0.02 cm/sec at rest and 0.45 cm/sec during exercise. Peak-to-peak variability was lowest in the mitral ring during rest (10-14%) and increased at peak exercise (15-21%). The proportion of segments eligible for analysis was 84% in the septum and 67% in the anterior wall during exercise. Thus, in patients with normal coronary arteries, tissue Doppler velocities decrease from base toward the apex during bicycle exercise. Interrater agreement is reduced during exercise and beat-to-beat variability is lowest in the mitral ring.
yes

Question: Does insulin , unlike food intake , suppress ghrelin in human subjects?
Answer: Unlike food intake, the administration of insulin and glucose does not suppress ghrelin levels. These data suggest that the suppressive effect of food intake or oral glucose on serum ghrelin is unlikely mediated by the changes of plasma insulin and glucose observed after the ingestion.
no

Question: Does behavioral and neural discrimination of speech sound after moderate or intense noise exposure in rats?
Answer: These results suggest that rats are able to adjust to the neural changes after moderate NE and discriminate speech sounds, but they are not able to recover behavioral abilities after intense NE. Animal models could help clarify the adaptive and pathological neural changes that contribute to speech processing in hearing-impaired populations and could be used to test potential behavioral and pharmacological therapies.
yes
