TASK 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.
PROBLEM: Question: Does chronic reduction of myocardial ischemia attenuate coronary collateral development in miniswine?
Answer: We conclude that growth and development of the coronary collateral circulation measured functionally during exercise at 90% of maximal heart rate is unrelated to the extent and duration of myocardial ischemia in this model.

SOLUTION: no

PROBLEM: Question: Does effective inhibition of nitric oxide production by aminoguanidine reverse hypotension in endotoxaemic rats?
Answer: AG inhibited NO formation in a dose-dependent way. Yet, AG had no haemodynamic effects, suggesting a minor cardiovascular influence of iNOS in this endotoxin model, in parallel to what has been found in microbial sepsis.

SOLUTION: no

PROBLEM: Question: Is the expression of Wnt-inhibitor DKK1 ( Dickkopf 1 ) determined by intercellular crosstalk and hypoxia in human malignant gliomas?
Answer: In this study, we showed for the first time that the expression of DKK1 was hypoxia dependent in human malignant glioma cell lines. The induction of DKK1 by intracellular crosstalk or hypoxia stimuli sheds light on the intense adaption of glial tumour cells to environmental alterations.

SOLUTION:
yes
