The influence on immunologic parameters during NOTES in a porcine survival model.

Objective: To analyze the effect of natural orifice transluminal endoscopic surgery (NOTES) on the survival of animals, by comparing the change of intraoperative and postoperative immunologic parameters of NOTES with laparoscopy.

Materials And Methods: Twenty pigs were randomized to treatment with NOTES or standard laparoscopy. Each group underwent diagnostic peritoneoscopy by laparoscopy or NOTES in 90 minutes.

Randomized clinical trial of single-incision versus conventional laparoscopic cholecystectomy: short-term operative outcomes.

Background: Single-incision laparoscopic surgery may reduce the complications of port site and postoperative pain. The improved cosmetic result also may improve the satisfaction of patients who have undergone surgery.

Methods: The study enrolled 108 patients who consecutively underwent laparoscopic cholecystectomy by the same surgeons and randomly divided them into single-incision laparoscopic cholecystectomy (SILC) and conventional laparoscopic cholecystectomy (CLC) groups.

A one-dimensional Ag coordination polymer: catena-poly[[[[N'-(4-cyano-benzyl-idene)nicotinohydrazide]silver(I)]-μ-N'-(4-cyano-benzyl-idene)nicotino-hydrazide] trifluoro-methane-sulfonate].

In the title compound, {[Ag(C(14)H(10)N(4)O)(2)]CF(3)SO(3)}(n), the unique Ag(I) ion is coordinated by two N atoms from two pyridine rings of two independent N'-(4-cyano-benzyl-idene)nicotinohydrazide ligands and one N atom of a carbonitrile group of a symmetry-related N'-(4-cyano-benzyl-idene)nicotino-hydrazide ligand, forming a distorted T-shaped coordination environment. One of the independent ligands acts as a bridge connecting Ag(I) ions, forming chains along the a axis. In the crystal structure, two neighbouring anti-parallel chains are connected through N-H⋯O hydrogen bonds.
