instruction:
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:
Question: Is cardiovascular variability similarly altered in coronary patients with normal left ventricular function and in heart failure patients?
Answer: Our study shows that in coronary patients with no MI and no left ventricular dysfunction, there is a profound alteration of both HR and BP variability as in CHF patients, presumably because of a marked impairment of the autonomic modulation of the heart and blood vessels.
answer:
yes


question:
Question: Does monosialotetrahexosylganglioside inhibit the Expression of p-CREB and NR2B in the Auditory Cortex in Rats with Salicylate-Induced Tinnitus?
Answer: These data suggest that chronic salicylate administration induces tinnitus via upregulation of p-CREB and NR2B expression, and that GM1 can potentially be used to treat tinnitus.
answer:
yes


question:
Question: Does serum α-hydroxybutyrate ( α-HB ) predict elevated 1 h glucose levels and early-phase β-cell dysfunction during OGTT?
Answer: Fasting serum α-HB levels predicted elevated 1 h glucose during OGTT, potentially due to impaired insulin secretion kinetics. This association persisted even in patients with an otherwise normal insulin-glucose homeostasis. Measuring serum α-HB could thus provide a rapid, inexpensive screening tool for detecting early subclinical hyperglycemia, β-cell dysfunction, and increased risk for diabetes.
answer:

yes
