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: Does maraviroc concentrate in the cervicovaginal fluid and vaginal tissue of HIV-negative women?
Answer: Higher maraviroc exposure in the female genital tract provides a pharmacologic basis for further evaluation of chemokine receptor 5 antagonists in HIV infection prophylaxis. This is the first study to report antiretroviral VT concentrations, CVF protein binding, and CVF terminal elimination.
[A]: yes


[Q]: Question: Is visceral pleural invasion a significant prognostic factor in patients with a part-solid lung cancer?
Answer: VPI may not contribute to the prognosis of patients with part-solid nodules. Thus, upgrading of the TNM stage on the basis of VPI should be carefully considered in these patients.
[A]: no


[Q]: Question: Does syngap1 haploinsufficiency damage a postnatal critical period of pyramidal cell structural maturation linked to cortical circuit assembly?
Answer: Pathogenic Syngap1 mutations have a profound impact on the dynamics and structural integrity of pyramidal cell postsynaptic structures known to guide the de novo wiring of nascent cortical circuits. These findings support the idea that disrupted critical periods of dendritic growth and spine plasticity may be a common pathologic process in developmental brain disorders.
[A]:
yes
