Is expression of nitrotyrosine associated with angiogenesis in esophageal squamous cell carcinoma?
Our data suggest that NO induces progression of esophageal carcinoma through its effect on angiogenesis, rather than its effect on tumor apoptosis.
Covering tonsillectomy field with mucosal palatopharyngeal arch flap significantly reduces pain after third postoperative day. The flap side had better healing when compared to denuded site. But the sutures in the mucosal flap may cause more tissue edema. Sutures have no significant effect on postoperative infection. Thus, mucosal flap may be used as an adjuvant surgical technique to decrease tonsillectomy pain of children in addition to the analgesic medication.
