Summary: The purpose of this study was to evaluate the survival rate of full-coverage tooth-supported fixed prosthetic restorations, including single crowns (SCs) and fixed dental prostheses (FDPs), and to consider the influences of tooth vitality, presence and type of post, and type of prosthetic restoration material. The results showed that SCs made of metal-ceramic and all-ceramic had the highest 5-year survival rate when the abutments were vital, while all-ceramic SCs with fiber post had a high survival rate when the abutments were non-vital. For FDPs, the survival rate was higher when the abutments were vital compared to non-vital, regardless of the presence, type of post, and FDPs material.

Summary: This study synthesized and characterized lignin-decorated zinc oxide nanoparticles and incorporated them into resin-modified glass ionomer cement (RMGIC) to enhance their anticariogenic potential and mechanical properties. The experimental groups demonstrated significantly greater anticariogenic potential compared to the control group. The shear bond strength test showed the highest value for the experimental group with the highest nanoparticle concentration, and the microhardness test yielded the highest value for the same group. Evaluation over 28 days indicated sustained anticariogenic potential without detrimental effects on shear bond strength and microhardness.

Summary: This study aimed to evaluate the incorporation of zirconia/silver phosphate nanoparticles in dental adhesives, measuring their physical and mechanical properties. The nanoparticles demonstrated antibacterial activities and inhibited biofilm formation. Higher concentrations of nanoparticles in the resin led to increased micro-hardness and flexural strength. Bond strength was higher on day 1 than on day 30, with the 0.5 wt.% group showing significantly higher values. Long-term color stability was observed for all samples. The experimental adhesives showed promise for clinical applications, but further investigations are needed.

Summary: Renewable energy can be obtained from wastewater by utilizing photocatalysis with Zinc oxide (ZnO), Copper-doped Zinc oxide (CuZnO), and Cobalt-doped Zinc oxide (CoZnO) nanostructures (NSs). The synthesized nanostructures showed good crystalline and structural stability, as confirmed by XRD and FESEM analysis. The highest photodegradation rate was observed on pH similar to 12 using ZnO, CoZnO, and CuZnO, and the photodegradation of methylene blue demonstrated the superior performance of ZnO, CuZnO, and CoZnO. Thus, CuZnO is recommended for industrial wastewater treatment like methylene blue.

Summary: Trauma, burns, and chronic illnesses can lead to non-healing wounds or defective healing, resulting in scar formation. The present study focuses on the development of highly compatible PLA-PHBV bilayer electrospun (ES) membrane dressings coated with chitosan polymer and pure plant extracts. These coated ES membranes are hydrophilic, carry and release the extracts, and have antibacterial potential. They also significantly promote wound healing in vitro compared to non-coated control ES membranes. Further molecular analyses and in vivo tests are needed to determine their effectiveness against scars and hyperpigmentation.

Summary: Soft tissue defects can be resolved with coated silk meshes, which have antimicrobial and wound healing properties. The coating alters the pore size and fiber diameter of the mesh, while also improving its mechanical strength. Among the variants tested, MHRJ showed the best cell viability and wound healing effects. In vivo experiments with rat hernia model confirmed the non-toxic nature and wound healing characteristics of the modified mesh. This study suggests that MHRJ could be a valuable biomedical implant.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.

Summary: This paper reviewed the primary methods for improving the overall properties of biodegradable zinc stents. It discussed the mechanical properties, degradation behavior, and biocompatibility of various improvement strategies. Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.
