Treatment Strategies for Refractory Catheter-Related Central Venous Occlusive Disorders: Review.

Background: Catheter-related central vein occlusive disease (CVOD) is a frequent complication in hemodialysis patients and significantly affects their prognosis. Current treatment options for catheter-related CVOD include standard guidewire and catheter techniques, radiofrequency ablation, and sharp recanalization. However, large-scale clinical trials evaluating these techniques are lacking, making CVOD management challenging.

Self-assembly CuO nanowire arrays on Cu mesh: A solid-state, highly-efficient, and stable photocatalyst for toluene degradation under sunlight.

Sunlight driven photocatalysis offers an effective and eco-friendly technology for volatile organic compounds (VOCs) removal. Three dimensional (3D) and oriented structure can facilitate efficient photon absorption and rapid diffusion of VOCs, which prevails over the powder-formed catalysts. Herein, free-standing and uniform p-type CuO nanowire (NW) arrays were obtained through heat treatment of Cu(OH) NWs, which were spontaneously grown from Cu mesh in air under room temperature for the first time.
