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 congenital penile pathology associated with abnormal development of the dartos muscle : a prospective study of primary penile surgery at a tertiary referral center?
Answer: Congenital penile pathology (hypospadias, buried penis) is associated with structural anomalies in dartos tissue. Further research is needed to unveil the pathophysiology of the condition.

SOLUTION: yes

PROBLEM: Question: Is expression of epigenetic modifiers significantly altered by exposure to secondhand smoke?
Answer: Quantification of the expression of genes encoding DNA methyltransferases (Dnmt1, Dnmt3a, Dnmt3b and Dnmt3l), methyl binding domain proteins (Mecp2, Mbd2 and Mbd3) and histone deacetylases (Hdac1 and Hdac2) by quantitative reverse-transcription polymerase chain reaction analysis showed modest but not statistically significant differences in the relative transcription of these key epigenetic regulators between SHS-exposed mice and age-matched controls. The non-significant changes in the expression of main epigenetic modifiers in SHS-exposed mice imply that SHS may predominantly induce genotoxic effects, particularly at non-tumorigenic doses, whereas epigenetic effects may only be secondary and manifest en route to tumor formation.

SOLUTION: no

PROBLEM: Question: Is poor prognosis indicated by nucleated red blood cells in peripheral blood associated with organ failure of the liver or kidney?
Answer: The detection of NRBCs in blood of surgical intensive care patients is of prognostic power with regard to patient mortality. This prognostic significance of NRBCs was independent of some clinical and other laboratory risk parameters. The appearance of NRBCs in blood was not associated with kidney failure or lesion of the liver.

SOLUTION:
no
