Example Output: no

Example Input: Question: Does cYP3A5 genotype influence everolimus in vitro metabolism and clinical pharmacokinetics in renal transplant recipients?
Answer: This study provides direct and indirect evidence that CYP3A5 genotyping cannot help improve everolimus therapy.
Example Output: no

Example Input: Question: Are the microneme proteins CTRP and SOAP essential for Plasmodium berghei ookinete to oocyst transformation in vitro in a cell free system?
Answer: Neither CTRP nor SOAP is required for parasite transformation in vitro. By-passing the midgut lumen allows for the transformation of P. berghei CTRP-KO ookinetes suggesting that it is not required for transformation in vivo.
Example Output:
no
