Summary: In this study, a transient photo-electro-thermal (TPET) technique was proposed for the measurement of thermal conductivity of thermoelectric thin films. By combining theoretical and experimental methods, it was found that the TPET technique using laser beam heating can effectively reduce the influence of Peltier effect and achieve high test accuracy. This technique is applicable to both free-standing and deposited thin films.

Summary: This study explored the interactions between gum arabic and alginate, finding that only specific fractions of gum arabic interact with alginate at pH 4. The intensity of interaction was significantly higher for glycoprotein compared to arabinogalactan protein. The findings suggest a potential electrostatic interaction between positively charged proteins in gum arabic and negatively charged carboxylate groups in alginate.

Summary: Modern-day treatment requires scarless wound healing with nanofiber mats as scaffolds, which are tissue and environment-friendly. The combination of neem gum polysaccharide (NGP) and polyvinyl alcohol (PVA) in the form of nanofibers exhibits antimicrobial properties and mimics the extracellular matrix for tissue growth. The optimized grade G14 of the nanofiber mats (NFM), crosslinked using glutaraldehyde vapors, shows maximum tensile strength, smooth surface morphology, hemocompatible properties, in-vitro biodegradability, and antimicrobial action against S. aureus & E. coli. Analytical techniques such as FTIR and TGA confirm the polymer-polymer compatibility of G14.

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.
