A dual-therapy sirolimus-eluting and CD34+ antibody-coated Combo Stent (DTS) has been developed to enhance endothelization and capture endothelial progenitor cells; however, vessel responses following DTS implantation remain unclear. Therefore, we evaluated early- and mid-term intravascular characteristics of DTS using intravascular imaging modalities. This multicenter, prospective, observational study enrolled 88 patients (95 lesions) who underwent DTS (43 patients, 48 lesions) or sirolimus-eluting Orsiro stent (SES, 45 patients, 47 lesions) implantation.

The development of efficient photocatalysts inspired by natural photosynthesis has drawn considerable interest for sustainable hydrogen (H) production. Among the various strategies for enhancing H evolution, constructing step-scheme (S-scheme) heterojunctions has attracted extensive interest, thanks to their limited charge recombination and enhanced charge transport in comparison to the traditional photocatalytic systems. Herein, we report the engineering of a novel S-scheme heterojunction by integrating ultrathin ZnInS (ZIS) nanosheets with MOF-derived N-doped NiO porous microrods (ZIS/N-NiO) toward superior photocatalytic behaviors.

The current study investigates and compares the biological effects of ultrathin conformal coatings of zirconium dioxide (ZrO) and vanadium pentoxide (VO) on osteoblastic MG-63 cells grown on TiO nanotube layers (TNTs). Coatings were achieved by the atomic layer deposition (ALD) technique. TNTs with average tube diameters of 15, 30, and 100 nm were fabricated on Ti substrates (via electrochemical anodization) and were used as primary substrates for the study.

Polymer heart valves are a promising alternative to bioprostheses, the use of which is limited by the risks of calcific deterioration of devitalized preserved animal tissues. This is especially relevant in connection with the increasingly widespread use of transcatheter valves. Advances in modern organic chemistry provide a wide range of polymers that can replace biological material in the production of valve prostheses.

Purpose: The purpose of this study was to investigate the influence of graphene oxide (GO) and hydrothermal aging on the biaxial flexural strength (BFS) and translucency (TP) of ultrathin monolithic zirconia with different yttria concentrations.
Methods: Disc shaped specimens (n = 120) were milled using zirconia blocks (YZ-HT [HT], YZ-ST [ST], and YZ-XT [XT]) with a diameter of 15.0 mm and a thickness of 0.
