Summary: Bacterial motility can be a significant predictor of AgNP resistance, guiding the development of nanoenabled antimicrobials. The study of bacterial resistance to AgNPs is still in its early stages, with limited understanding of the underlying mechanisms. The resistance to subinhibitory concentrations of AgNPs in Escherichia coli K-12 MG1655 strain was found to be associated with a cusS mutation, potentially enhancing silver ion efflux and suggesting a role for flagellum-based motility in the resistance mechanism.

Summary: Streptomyces spores can utilize the motility machinery of other soil bacteria to be transported to plant tissues by interacting with the flagella of both gram-positive and gram-negative bacteria. This highlights the capability of nonmotile bacteria to use the motility machinery of other microbes to complete necessary stages of their lifecycle.

Summary: The effect of chloride ions on the antimicrobial activity of silver composites was investigated. The adsorption of chloride ions by a composite formed by chitosan and natural zeolite with supported silver nanoparticles obtained by gamma irradiation was also considered. The presence of chloride ions in the solution was found to increase the cell decay time, while without chloride ions, the microbial mortality rate reached 100% within two hours.

Summary: This study evaluated the effects of biologically synthesized silver and copper nanoparticles on bacterial attachment and viability of dormant cells within the biofilm matrix. The nanoparticles significantly reduced bacterial attachment and viable cells in the biofilm matrix, and eradicated mature biofilms formed by various Gram-negative pathogens. Furthermore, they also reduced the expression of biofilm-associated genes. Therefore, these nanoparticles could be used as adjuvant therapy in the eradication of antibiotic resistance and biofilm matrix associated with Gram-negative bacterial infection.

Summary: Lactose is the main sugar in milk and serves as the main energy source for infants. Lactose intolerance can cause symptoms like diarrhea and abdominal cramping, and an estimated 30% of the population in developing countries may suffer from this condition. Lactic acid bacteria may aid in digesting lactose in fermented dairy products, potentially benefiting those with lactose intolerance.

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.
