Summary: Heating in a nitrogen atmosphere can improve the tribological properties of titanium alloys but reduces their strength. A rapid nitriding method involves bombarding the surface of a titanium alloy with commercially pure titanium fine particles with a nitrided phase at room temperature, forming a nitrided layer within a short period. This method resolves the trade-off between the rapid formation of a nitrided layer and the suppression of grain coarsening for titanium alloys.

Summary: This study is the first to use RNA sequencing to investigate the genome-wide transcriptional profiling of osteoblasts in response to different titanium surface topographies. The findings reveal that osteoblasts on microrough surfaces exhibit upregulated expression of genes involved in immune system, stress/stimulus responses, proliferation control, and signaling pathways.

Summary: The study found that the surface roughness of titanium implants affects their osteogenic potential, with sandblasted/large-grit/acid-etched (SLA) surfaces showing superior osteogenic response compared to machined surfaces, likely due to a different epigenetic landscape, particularly DNA methylation of the Alp gene.

Summary: The study involved preparing a regular nanotube array on titanium surface by anodization, followed by immobilizing a complex of chitosan and zinc ions (CS/Zn) to enhance biocompatibility. The CS/Zn coating not only promoted adhesion and proliferation of osteoblasts, but also up-regulated expression of ALP and OCN. Overall, this method can improve osteogenesis and osteointegration of titanium surface.

Summary: Ti6Al4V-equine bone nanocomposites fabricated by powder metallurgy and heat treatment exhibit excellent biocompatibility and corrosion resistance. The high hydroxyapatite content in equine bone enhances cell adhesion and proliferation on the composite surface. Additionally, the inclusion of equine bone particles in the composite matrix improves corrosion resistance by interfering with the transfer of metal ions.

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: Human skin equivalents (HSEs) play a crucial role in tissue engineering. This study introduces a 3D-printed culture insert to apply a static radial constraint on HSEs and examines its effects on tissue characteristics. The results show that the diameter of the culture insert significantly influences tissue contraction, fibroblast and matrix organization, keratinocyte differentiation, epidermal stratification, and basement membrane formation. This study provides important insights for the design of skin tissue engineering.

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.
