Summary: This study investigates the effect of various factors on the bond strength of hydroxyapatite coatings on 316L Stainless Steel substrates. The results show that the bond strength is influenced by sonication temperature, time, and acetone concentration. The highest bond strength is achieved at a sonication temperature of 45 °C, time of 15 minutes, acetone concentration of 99%, and yields a bond strength of 91.35 Mpa.

Summary: MgFe-LDHs films, MgFe-LDO films, HA films, and MgFe-LDO&HA films were prepared on the 316L stainless steel surface through hydrothermal method and sol-gel method. The morphology, composition, and structure of the films were analyzed using SEM, EDS, XRD, and FT-IR. EIS and potentiodynamic polarization curves were used to evaluate the corrosion behavior and properties of the coatings. Results show that MgFe-LDO&HA films exhibit better corrosion resistance in SBF compared to HA films due to the more uniform and dense structure of the composite films. Animal muscle tissue embedding experiments demonstrate that MgFe-LDO&HA films maintain good biocompatibility and integrity.

Summary: As 316L stainless steel is commonly used in manufacturing biomedical devices, its inadequate biological reactions often cause failure of these devices shortly after implantation. To address this issue, a Tantalum (Ta) coating was applied on the surface of 316L stainless steel to improve biocompatibility and hydrophilicity. Cell culture experiments and scratch tests showed that the Ta-coated surfaces had improved cell adherence, proliferation, differentiation, and adhesion strength compared to bare 316L SS. Based on these findings, the Ta-coated 316L stainless steel is considered a promising material for orthopedic applications due to its improved biocompatibility and surface properties.

Summary: Rough surfaces with scratches were found to enhance cavitation erosion resistance, especially in the early stage. The effect of scratches on the cavitation erosion resistance of coatings was greater than that on substrates. Moreover, rough surfaces with initial surface scratches could extend the incubation period of 316L stainless steel substrates. This study could also be used as a reference for investigating the cavitation erosion behaviors of materials with specific surface features.

Summary: This study investigates the tribocorrosion behavior of untreated, plasma nitrided, Ti-DLC coated, and duplex treated AISI 316L stainless steel. The results show that the wear mechanism causes much more damage than corrosive effects. Generally, the wear and tribocorrosion performance of the treated samples increase compared to the untreated sample, thanks to the layers formed on the surface. The best tribocorrosion resistance is observed in the duplex surface-treated sample.

Summary: Decellularized tissues, particularly Wharton's jelly (WJ), show promising potential in the field of regenerative medicine by promoting wound closure and reducing infections. In this study, decellularized WJ exhibited inherent effects on the growth and adhesion of both Gram positive and Gram negative bacteria. Furthermore, it was found that macrophages changed their phenotypes in the presence of decellularized WJ. Additionally, subcutaneous implantation of decellularized WJ resulted in complete absorption without any foreign body reaction.

Summary: In inflammatory diseases, the excessive activation of polymorphonuclear neutrophils (PMNs) can lead to tissue damage. This study investigated the effects of two novel compounds, 4aa and 4ba, on PMNs activation and found that they can reduce the release of inflammatory cytokines, decrease PMNs phagocytic ability, and limit the recruitment of PMNs in tissues. These findings suggest the therapeutic potential of these compounds in the treatment of inflammatory diseases.

Summary: Osteoblasts and Staphylococcus aureus interactions can lead to impaired bone homeostasis. This study found that human osteoblast culture supernatant has a moderate effect on S. aureus biofilm formation, but does not significantly change the biofilm matrix or regulation of biofilm-related genes. Additionally, the sensitivity of S. aureus to bone cell secretions is strain-dependent.

Summary: In order to make the cementitious ink suitable for printing, it needs to have contradictory properties - fluid enough to be pumpable and extrudable initially, but quick to stiffen after deposition for buildability. This study aims to compare experimental protocols for mechanical characterization and assess the drop in bond strength with different printing parameters. Classical microindentation tests and a new method for multidirectional compression testing were conducted. Results validate the new experimental procedure and show a weakening and widening of the interface over time, as well as anisotropy in multidirectional compression tests and lower adherence with a larger time gap between layers in instrumented macroindentation.

Summary: This study investigates the effects of different alloying elements on the corrosion resistance and antibacterial performance of two copper alloys. The results show that the nature of the alloying elements significantly influences the corrosion resistance and antibacterial performance. An organic film on the substrate acts as a protective barrier and decreases the antimicrobial performance of copper-based materials.

Summary: This study presents a mechanical investigation of Constantan thin films deposited on a silicon wafer substrate using a cathodic sputtering technique. A modified contact area function method is proposed for data processing of nanoindentation to extract the Martens hardness of the substrate, titanium layer, and Constantan films. The Martens hardness of the substrate and titanium layer were found to be equal, indicating that the influence of the titanium layer on film hardness can be neglected. Additionally, the hardness of the Constantan films was constant while the substrate hardness varied with film thickness, which can be attributed to the brittleness of the substrate and film compacting.

Summary: Infections are a critical issue during the development of biomimetic materials for bone regeneration. Calcium phosphate and collagen substrates may favor bacterial adhesion. Staphylococcus aureus possesses adhesins that allow binding to these substrates, leading to the development of biofilms highly tolerant to immune system attacks or antibiotic treatments. Therefore, choosing the right material for bone substitutes is crucial to prevent bacterial adhesion and reduce the risk of bone and joint infections.

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.
