Ex Input:
Question: Is cytosine deamination a major cause of baseline noise in next-generation sequencing?
Answer: Baseline noise during NGS is mostly due to cytosine deamination, the source of which is likely to be both biologic and an artifact of thermocycling, and it can be reduced by UNG pretreatment.

Ex Output:
yes


Ex Input:
Question: Does ischemic preconditioning attenuate renal ischemia-reperfusion injury by inhibiting activation of IKKbeta and inflammatory response?
Answer: The evidence suggests that IKKbeta may play a role in renal I/R injury and give rise to the generation of NGAL. It appears that IPC may attenuate renal injury and the expression of NGAL following acute I/R injury. IKKbeta may offer a clinically accessible target for preventing renal injury following I/R.

Ex Output:
yes


Ex Input:
Question: Do thyroid hormones affect recovery from depression during antidepressant treatment?
Answer: Our study suggests that thyroid hormones may have an impact on severity and efficacy of antidepressant treatment. However, our result should be considered with caution and merely as a suggestion due to some methodological limitations. Hence further studies are required to better ascertain the role of thyroid hormones in depression after menopause.

Ex Output:

yes
