Input: Consider Input: Question: Do dual inhibition of nuclear factor kappa-B and Mdm2 enhance the antitumor effect of radiation therapy for pancreatic cancer?
Answer: Combination therapy of radiation with nafamostat mesilate exerts enhanced anti-tumor effect against human pancreatic cancer.

Output: yes


Input: Consider Input: Question: Is radiological review of specimen radiographs after breast localisation biopsy always necessary?
Answer: This study shows that a suitably trained or experienced surgeon can assess specimen radiographs effectively without the need for intraoperative radiological input although complete histological resection is not guaranteed despite specimen radiographs demonstrating clear margins.

Output: no


Input: Consider Input: Question: Is gene transfer in vitro and in vivo by cationic lipids significantly affected by levels of supercoiling of a reporter plasmid?
Answer: In considering a specification for the amount of supercoiled plasmid in a gene therapy product, it must be noted that the relaxed forms of the plasmid are no less efficient at gene delivery than the supercoiled forms.


Output: no
