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: Does transient ischemia limit subsequent ischemic regional dysfunction in humans : a transesophageal echocardiographic study during minimally invasive coronary artery bypass surgery?
Answer: Ischemic dysfunction was precipitated by the 5-min LAD occlusion, as shown by the increase in LVWMS and pulmonary artery pressure. However, a 5-min coronary occlusion and the resulting ischemia do not alter regional left ventricular systolic function during subsequent ischemia in humans.
answer:
no

question:
Question: Is central venous saturation an alternative to mixed venous saturation during cardiopulmonary bypass in coronary artery surgery patients?
Answer: Although mean biases between the measurements were low, limits of agreement were too large to provide a clinically acceptable estimation of SvO(2) by ScvO(2) in these conditions. Variations in regional oxygen consumption seem to be the main factor worsening the relationship.
answer:
no

question:
Question: Is the multidrug resistance 1 ( MDR1 ) gene polymorphism G-rs3789243-A associated with disease susceptibility in Norwegian patients with colorectal adenoma and colorectal cancer ; a case control study?
Answer: The MDR1 intron 3 (G-rs3789243-A) polymorphism was not associated with a risk of colorectal adenomas or carcinomas in the present Norwegian study group. Thus, this MDR1 polymorphism does not seem to play an important role in colorectal carcinogenesis in this population.
answer:
no
