Colostomy reversal after oncological resections versus non-oncological resections is not associated with worse postoperative outcomes – the results of the Polish Liquidation of Colostomy (LICO) study

Wojciech M. Wysocki, Michał Kisielewski, Natalia Dowgiałło‐Gornowicz, Wiktor Krawczyk et autres

Introduction: Colostomy reversal is a common surgical procedure following oncological and non-oncological resections. Colostomy reversal is performed in 60% in of non-oncological patients, and in only 40% of patients operated on for oncological reasons. Postoperative course as a possible reason for a …

Preliminary results of Polish national multicenter study on colostomy reversal – LICO (Liquidation of Colostomy) study

Michał Kisielewski, Tomasz Wojewoda, Karolina Richter, Michał Wysocki et autres

Introduction: Creation of colostomy is still a commonly performed procedure in emergency settings, when intestinal anastomosis cannot be performed safely. Reversing a stoma has been linked with high rates of morbidity and also mortality. Aim: The primary goal of the study was …

Synthesis and Spectroscopic Characterization of Selected Water-Soluble Ligands Based on 1,10-Phenanthroline Core

Jacek E. Nycz, Natalia Martsinovich, Jakub Wantulok, Tieqiao Chen et autres

Water-soluble ligands based on a 1,10-phenanthroline core are relatively poorly studied compounds. Developing efficient and convenient syntheses of them would result in new interesting applications because of the importance of 1,10-phenanthrolines. In this manuscript, we describe novel and practical ways to introduce …

Spectroelectrochemical Properties of 1,10‐Phenanthroline Substituted by Phenothiazine and Carbazole Redox‐active Units

Jakub Wantulok, Romana Sokolová, Ilaria Degano, Viliam Kolivoška et autres

Abstract Complexes of 1,10‐phenanthrolines with cations of transition metals have broad range of applications. This work aims at designing and investigating phenothiazine and carbazole substituted 1,10‐phenanthrolines as ligands for future complexes with transient metal cations. The combined electrochemical, spectroelectrochemical and DFT studies …

Direct Amination of Nitroquinoline Derivatives via Nucleophilic Displacement of Aromatic Hydrogen

Jakub Wantulok, Jacek E. Nycz, Maria Książek, Joachim Kusz et autres

The vicarious nucleophilic substitution of hydrogen (VNS) reaction in electron-deficient nitroquinolines was studied. Properties of all new products have been characterized by several techniques: MS, HRMS, FTIR, GC-MS, electronic absorption spectroscopy, and multinuclear NMR. The structures of 4-chloro-8-nitroquinoline, 8-(tert-butyl)-2-methyl-5-nitroquinoline, 9-(8-nitroquinolin-7-yl)-9H-carbazole and (Z)-7-(9H-carbazol-9-yl)-8-(hydroxyimino)quinolin-5(8H)-one …
