Summary: Chondroitin sulphate (CS) proteoglycans, which are closely associated with the stem cell niche of articular cartilage, were found to be present in the subepithelial corneal stroma and nearby ossicles in the adult chicken cornea. When cultivated on CS/dermatan sulphate (DS)-coated dishes, corneal stromal cells exhibited a less-differentiated phenotype and expressed stem cell markers. These findings suggest that CS/DS may play a role in maintaining a stem cell phenotype in corneal cells.

Summary: This study aimed to enhance the therapeutic efficacy of long-term oral tofacitinib (TOF) administration by coating chondroitin sulphate (CS) onto proglycosomes and anchoring high-affinity CS to CD44 receptors on immune cells in the inflammatory region. The optimized CS-TOF-PG showed small particle sizes and high entrapment efficiency. Ex-vivo studies demonstrated that CS-TOF-PG gel exhibited higher flux and dermal retention compared to FD-gel. In vivo efficacy studies revealed that CS-TOF-PG significantly reduced inflammation compared to oral TOF and FD gel.

Summary: This paper describes the surface modification of polytetrafluoroethylene (PTFE) through plasma treatment. By optimizing various parameters, such as active gases, RF power, distance between the plasma source and sample, and plasma duration, the hydrophobic nature of PTFE was successfully reduced. The results showed that using N-2 as an active gas in plasma treatment significantly improved the wettability of the PTFE membrane. Various surface characterizations were used to verify the modified PTFE surface, which revealed significant surface modifications but non-uniform fiber alignment and torn fibers in some areas.

Summary: In this study, we investigated the hydrophilic surface modification of SiOx containing amorphous hydrogenated carbon nanocomposite films (DLC:SiOx) through atmospheric oxygen plasma treatment. The modified films showed effective hydrophilic properties with complete surface wetting. The treatment process increased the surface roughness and changed the surface chemical states, leading to the enrichment of hydrophilic chemical bonds and removal of hydrophobic functional groups.

Summary: This article investigates the surface modification of polyethylene (PE) using atmospheric pressure plasma jets. The results show that the use of a premixed gas containing 90% argon and 10% CH4 leads to a smaller jet length, a shift in the transition point from laminar to turbulent regime, and the appearance of CH, H-2 and C-2 emissions. Surface treatment of PE using both laminar and turbulent regimes improves its hydrophilicity due to the incorporation of oxygen groups (C=O), but the use of pure argon plasma induces surface degradation compared to Ar/CH4 plasma due to higher excited species.

Summary: Due to the increase of service temperature, the bond strength of polyimide composite film decreases significantly. This study proposes a double-layer structure consisting of a polyimide substrate and Polyetheretherketone coating to improve the adhesion between them. Atmospheric plasma treatment is used to enhance the PI/PEEK interface adhesion. Surface properties of PI films, such as wettability, chemical structure, element analysis, morphology, and roughness, were studied. The surface free energy increased after plasma treatment, and reactive groups containing oxygen were generated. The adhesion between PI film and PEEK coating was increased by exposing the inorganic particles on the PI film surface through plasma etching. The relative energy change and reactivity sequence of functional groups were simulated.

Summary: Biodegradable metals, such as zinc-based materials, have become popular for biomedical applications due to their ability to assist in tissue healing. This study investigated the combined effect of minor iron addition and a polyethylene glycol (PEG) coating on the surface morphology, degradation, cytotoxicity, and mechanical properties of zinc-based materials. The results showed that the addition of iron and polymer coating had a positive effect on degradation rate and mechanical properties, but led to a reduction in biocompatibility.

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.
