[Open observational study with a retrospective analysis of the efficacy and tolerability of aceclofenac in patients with acute non-specific low back pain].

Objective: To analyze the efficacy and tolerability of aceclofenac in the treatment of patients with acute non-specific musculoskeletal pain in the lower back (ANBP) compared with other NSAIDs (dexketoprofen, nimesulide and lornoxicam), as well as to assess the impact of NSAIDs therapy on the relative risk of recurrence and chronicity of this pathology.

Material And Methods: The study involved 80 patients (47 women and 33 men), average age 52.6 [47.

Iron Oxide Nanoparticle-Assisted Delamination of TiCT MXenes: A New Approach to Produce Magnetic MXene-Based Composites.

TiCT MXene is one of the most comprehensively studied 2D materials in terms of its adsorptive, transport, and catalytic properties, cytotoxic performance, etc. Still, conventional MXene synthesis approaches provide low single-flake MXene yield and frequently uncontrollable properties, demanding further post-processing. The MXene family also lacks magnetism, which is helpful for producing effective nanoadsorbents as their magnetic decantation is the cheapest and most convenient way to remove the spent adsorbent from water.

[Indocyanine green in liver transplantation].

The purpose of this study was to evaluate the first own experience of using indocyanine green (ICG) in liver transplantation compared to literature data and to determine its potential for clinical practice. Liver transplantation is an effective option for patients with end-stage disease, but this procedure is associated with many problems such as graft rejection, graft dysfunction, surgical risk and postoperative management. Modern methods for assessing graft function have their limitations, so a more efficient method is needed.

New Titanium(IV)-Alkoxide Complexes Bearing Bidentate OO Ligand with the Camphyl Linker as Catalysts for High-Temperature Ethylene Polymerization and Ethylene/1-Octene Copolymerization.

In order to increase the thermal stability of olefin polymerization precatalysts, new titanium(IV) complexes with diolate ligands differing in the degree of steric hindrances were synthesized from readily available precursor (±)camphor. The structures of the complexes were established by X-ray diffraction. Complexes in the presence of an activator {EtAlCl + BuMg} catalyzed the synthesis of UHMWPE with an M up to 10 million and a productivity of up to 3300 kg/mol·atm·h.
