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: Is cerebral acetylcholinesterase activity decreased in MS patients with cognitive impairment?
Answer: In the patient group regional AChE activities had inverse correlations with Word learning and MMSE (Mini-Mental State Examination) scores. In the group of cognitively deteriorated MS patients no change in cerebral AChE activity, compared with controls, was observed, but within the patient group more pronounced cognitive symptoms were associated with higher cerebral AChE activity.

SOLUTION: no

PROBLEM: Question: Is vitamin D deficiency independently associated with greater prevalence of erectile dysfunction : The National Health and Nutrition Examination Survey ( NHANES ) 2001-2004?
Answer: In this cross-sectional analysis of a representative sample of U.S. men, vitamin D deficiency was associated with an increased prevalence of ED independent of ASCVD risk factors. Additional research is needed to evaluate whether treating vitamin D deficiency improves erectile function.

SOLUTION: yes

PROBLEM: Question: Does preconditioning prevent postischemic dysfunction in aging heart?
Answer: Preconditioning transient ischemic stimulus significantly reduces postischemic dysfunction in adult but not in senescent hearts, whereas exogenous norepinephrine is able to mimic preconditioning in both adult and senescent hearts. Ischemic preconditioning induces an increase in norepinephrine release in adult but not in senescent hearts. Preconditioning induced by transient ischemic stimulus and norepinephrine was abolished by alpha-adrenergic receptor blockade in both adult and senescent hearts. Thus, our data demonstrate that preconditioning is absent in aging heart and is probably related to the reduction of norepinephrine release and alpha-adrenergic receptor stimulation in response to ischemic preconditioning.

SOLUTION:
no
