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.

[Q]: Question: Is lymphocyte inhibition compromised in mesenchymal stem cells from psoriatic skin?
Answer: This study demonstrated abnormalities in MSCs derived from psoriatic skin lesions. We suggest that the attenuated inhibitory effect on T-cell proliferation might be one of the pathogenic mechanisms of psoriasis.
[A]: yes


[Q]: Question: Does a common variant in the precursor miR-146a sequence predispose to cholangiocarcinoma in a large European cohort?
Answer: Our data do not support a prominent contribution of the pre-miR-146a sequence variant in the genetic predisposition to CCA. However, current studies functionally characterizing rs2910164 have proposed that distinct repertoires of target genes are addressed by genotype-specific mature miR-146a species. Given the detected trend towards a potentially protective role of GC heterozygosity, a subtle modulation of genetic CCA risk by the pre-miR-146a GC genotype may exist and should be evaluated further.
[A]: no


[Q]: Question: Are paraoxonase ( PON1 ) polymorphisms Q192R and L55M associated with human longevity : A meta-analysis?
Answer: No evidence that the Q192R and L55M polymorphisms of PON1 impacted on the probability of reaching extreme ages was found although this cannot be completely ruled out; however, the possibility of population-specific effects due to the influence of and interaction between different genes or environmental factors could not be ruled out.
[A]:
no
