question:
Question: Is plasminogen activation by fibroblasts from periodontal ligament and gingiva directly affected by chemokines in vitro?

answer:
no

question:
Question: Does transoral incisionless fundoplication significantly increase morbidity of subsequent laparoscopic Nissen fundoplication?
Answer: Severe recurrent gastroesophageal reflux necessitating laparoscopic Nissen fundoplication occurs in a subset of patients following TIF. In this series, previous TIF did not result in prolonged operative times, significant operative hemorrhage, or iatrogenic hollow viscus injury. These data suggest that laparoscopic Nissen fundoplication can be safely performed in this patient population without increased operative morbidity.
answer:

no
