Summary: Plastic waste is a major issue in modern society, and there is a need for environmentally friendly disposable materials. In this study, gelatin blends modified with polysaccharides were produced and characterized using various techniques. The addition of agarose increased the hardness, surface energy, softening point, and glass transition temperature of the blend. The addition of starch increased the softening point and glass transition temperature. Aging affected the hardness and tensile strength of both blends.

Summary: The diffusion kinetics of vitamin B6 from composite gels of gelatin and agarose were studied using blending law and diffusion modelling. Structural properties of the composite gels were analyzed using various techniques, including FTIR, XRD, CLSM, and small-deformation dynamic oscillation in shear. UV-vis spectroscopy was employed to study the diffusion kinetics of vitamin B6. The results showed that blending law-based diffusion theory can predict the diffusion kinetics of bioactive compounds in aqueous composite gels.

Summary: Agarose/fish gelatin double-network hydrogels (DNs) were fabricated and compared with beef tendons and single-network hydrogels. Increasing the concentration of fish gelatin significantly improved the mechanical strength and toughness of the DNs, while a moderate increase in agarose concentration only improved the mechanical strength. The DNs had higher hardness, water holding capacity, and lower swelling rate compared with single-network hydrogels, and showed a high correlation with beef tendons, indicating their potential as artificial food.

Summary: A novel gelatin-based adhesive hydrogel was successfully prepared using mussel-inspired chemistry, showing hemostatic properties in a rat hepatic hemorrhage model. The incorporation of graphene oxide enhanced the conductivity and mechanical properties of the hydrogels, enabling successful monitoring of EMG signals and demonstrating good cytocompatibility in L929 cell experiments. These results suggest the potential application of GelDA/GO hydrogels in tissue adhesives, wound dressings, and wearable devices.

Summary: Sonochemistry utilizes ultrasound to generate reactive radicals, offering a green alternative for hydrogen production, wastewater treatment, and chemical synthesis. Conventional sonochemical reactors often have design limitations resulting in low efficacy and slow reaction kinetics. A novel reactor design was constructed, creating intense localized high pressure amplitudes capable of spontaneous cavitation, leading to significantly higher hydroxyl radicals production rate and sonochemical efficiency.

Summary: We have synthesized hydroxyl-radical (OH) responsive fluorescent probes using the 3,5-dihydroxybenzyl (DHB) functionality. In the presence of OH radicals, Umb-DHB and Res-DHB showed significant increases in fluorescence emission intensities at 460 nm and 585 nm respectively. Incubating Res-DHB in HeLa cells followed by therapeutic ultrasound resulted in a significant increase in fluorescence emission intensity, allowing the monitoring of ultrasound-induced OH production in live cells.

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.
