Input: Consider 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.

Output: yes

Input: Consider Input: Question: Does patient-prosthesis mismatch in patients undergoing bioprosthetic aortic valve implantation increase risk of reoperation for structural valve deterioration?
Answer: Patients suffering from mismatch were twice as likely to undergo reoperation for aortic bioprosthesis replacement for SVD than those without mismatch.

Output: yes

Input: Consider Input: Question: Does intravitreal Injection of Normal Saline induce Retinal Degeneration in the C57BL/6J Mouse?
Answer: NS is toxic to the C57BL/6J mouse retina and should not be used as a vehicle for intraocular injection. PBS is not toxic to the retina and is a preferred vehicle.
Output: yes
