Antimicrobial Activity of Anionic Bis(-Heterocyclic Carbene) Silver Complexes.

The antimicrobial properties of a series of anionic bis(carbene) silver complexes Na[Ag(NHC)] were investigated (- and , where NHC is a 2,2'-(imidazol-2-ylidene)dicarboxylate-type -heterocyclic carbene). The complexes were synthesized by the interaction of imidazolium dicarboxylate compounds with silver oxide in the presence of aqueous sodium hydroxide. Complexes , were characterized analytically and spectroscopically, and the ligand precursor and complexes and were structurally identified by X-ray diffraction methods.

Lateral unicompartmental knee arthroplasty: is really a good option?

Introduction: Lateral unicompartmental knee arthroplasties (LUKA) account for only < 1% of all knee arthroplasties and for only 5-10% of all unicompartmental knee replacements. This means that there is less published literature on these procedures and that the surgeon's experience with them is smaller than with medial UKA. The aim of this study was to analyze the survival and the clinical-functional outcomes of LUKA according to the type of bearing surface (all-polyethylene versus metal-backed) used.

Megaprosthesis use in Paprosky III/IV femoral defects in non-oncological patients: analysis of survival, clinical, and functional outcomes after an average follow-up of five years.

Purpose: To determine the survival and patient-reported outcomes in non-oncological patients treated with proximal femoral resection (PFR) using MEG for femoral reconstruction.

Materials And Methods: This retrospective study included 16 patients. Demographic variables and complications developed were analyzed.

Electroassisted Incorporation of Ferrocene within Sol-Gel Silica Films to Enhance Electron Transfer.

The sol-gel method is a straightforward technique that allows electrode modification with silica thin films. Furthermore, the silica pores could be functionalized to enhance the electrical conductivity and reactivity of the silica films. In this context, silica thin films were functionalized with ferrocene species.
