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 hIC2 a novel dosage-dependent regulator of cardiac development located within the distal 22q11 deletion syndrome region?
Answer: Our results demonstrate a novel role for Hic2 in cardiac development. Hic2 is the first gene within the distal 22q11 interval to have a demonstrated haploinsufficient cardiac phenotype in mice. Together our data suggest that HIC2 haploinsufficiency likely contributes to the cardiac defects seen in distal 22q11 deletion syndrome.

A: yes

Q: Question: Are wedding rings a significant source of bacterial contamination following surgical scrubbing?
Answer: This preliminary study would suggest that a traditional band wedding ring is not a source of a bacterial load following a standard surgical scrub procedure and, as such, there is no requirement for their removal pre-operatively.

A: no

Q: Question: Is body mass index associated with higher Gleason score and biochemical recurrence risk following radical prostatectomy in Chinese men : a retrospective cohort study and meta-analysis?
Answer: The present study suggested that higher BMI was an independent risk factor for a higher Gleason score, as well as an independent predictor of BCR after radical prostatectomy in Chinese patients. Meta-analysis of Asian studies also indicated that obese patients, although without statistical significance, might be more likely to suffer from BCR.

A:
yes
