Summary: Under ultrasonication, Cu2O microparticles are fragmented into NPs and strongly interact with alkali lignin to form a nanocomposite. The L-Cu nanocomposite exhibits enhanced antibiofilm activities against various pathogens. Experimental evidence reveals the destruction of bacterial cell walls by L-Cu, leading to the loss of structural morphology. The MICs for biofilm inhibition and bacterial eradication vary for different pathogens, highlighting the potential of L-Cu as an alternative to neutralize MDR pathogens.

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.
