question:
Question: Is visceral pleural invasion a significant prognostic factor in patients with a part-solid lung cancer?
Answer: VPI may not contribute to the prognosis of patients with part-solid nodules. Thus, upgrading of the TNM stage on the basis of VPI should be carefully considered in these patients.
answer:
no


question:
Question: Do nAT1 genotypes predict response to mesalamine in patients with ulcerative colitis?
Answer: NAT1 genotypes do not predict response or side effects to mesalamine in patients with UC. Variations caused by non-genomic effects may be associated with the clinical response to 5-ASA.
answer:
no


question:
Question: Do plasma cytokines reflect expression of pro- and anti-inflammatory cytokine mRNA at organ level after cardiopulmonary bypass in neonatal pigs?
Answer: The cytokine mRNA expression pattern was very different for the pigs killed already 0.5 h after the CPB procedure compared with the pigs killed 4 h post-CPB. The plasma cytokine levels poorly reflected mRNA expression of the pro- and anti-inflammatory cytokines.
answer:

no
