Background/aim: The aim of this study was to analyze survivorship and functional outcome of cementless spongy metal structured total hip arthroplasty (THA) after ultra-long-term follow-up.
Patients And Methods: A total of 100 THAs in patients under 65 years at initial surgery were performed between 1985 and 1989 at our Department. Twenty patients (23 hips) were available for final follow-up. Implant survivorship and functional results (Merle d'Aubigné, SF-12) were assessed.
Results: At a mean follow-up of 30 years (range=27.7-31.7 years), the overall stem survival rate was 82.6% (19/23 stems) and the overall cup survival rate was 52.2% (12/23 cups). Revision surgeries were performed for aseptic loosening in all cases. Functional evaluation revealed good to excellent results in 16 patients (80%) Conclusion: Spongy metal structured cementless THA provides remarkable survivorship and excellent functional results even after ultra-long-term follow-up. Further research regarding modern implants, bearing surfaces etc. is required to assess survivorship and clinical outcomes of different implant designs.

The most time-consuming aspect of dental prosthesis installation is the osseointegration of a metal implant with bone tissue. The acceleration of this process may be achieved through the use of extracorporeal shock wave therapy. The objective of this study is to investigate the conditions for osseointegration of the second premolar implant in the mandibular segment through the use of a poroelastic model implemented in the movable cellular automaton method.

The fully porous structure of the Lübeck prosthesis is designed to closely resemble cancellous bone. Several studies have reported 'good' to 'excellent' mid- to long-term results for use of the Lübeck, but stem fractures have been reported as a complication. We report on the case of an 85-year-old patient who underwent total hip arthroplasty (THA) using the Lübeck more than 25 years ago who underwent revision surgery for management of two periprosthetic femoral fractures and a stem fracture.

Iron nitrides with the merits of high theoretical capacities, cost-effectiveness, and good electronic/ionic conductivity have been recognized as attractive anode candidates for lithium-ion batteries (LIBs). Carbon compositing, pore engineering, and nanostructure construction have proved to be effective strategies to prepare high-performance metal nitride anodes for LIBs. Herein, we synthesized a series of FeN-embedded and N-doped carbon nanorods (FeN@NCNR) with a hierarchical porous system and controllable topography by metal-catalyzed graphitization-nitridization of the Fe(III)-triazole framework (Fe-MOF) and thermal evaporation of the triblock copolymer F127 template assembled in Fe-MOF via hydrogen bonding interaction, followed by the air oxidation and urea-assisted ammonolysis processes.

Article Synopsis
- - Phenoxy carboxylic acid herbicides (PCAs) are persistent pollutants that can harm both the environment and human health, with strict drinking water limits set globally for compounds like 2,4-dichlorophenoxyacetic acid.
- - Metal-organic frameworks (MOFs) are promising materials for detecting PCAs due to their high surface area and excellent adsorption abilities, but their practical use is hindered by challenges in isolating them and inefficiencies in liquid-phase mass transfer.
- - The study explores creating a greener and more efficient method for preparing MOF aerogels, which combine the desirable properties of MOFs with aerogels' unique structure to enhance their adsorption efficiency for target molecules.

The "one-pot" cascade process involves multiple catalytic conversions followed by a single workup stage. This method has the capability to optimize catalytic efficiency by reducing chemical processes. The key to achieving cascade reactions lies in designing cascade catalysts with well-dispersed, stably immobilized, and accessible noble metal nanoparticles for multiple catalytic conversions.
