Summary: This work presents the targeted modification of carbon paste (CP) by adding conductive graphene oxide (GO) and mesoporous natural zeolite with Ni2+ cations (NiZ), which enhances the electrocatalytic properties. A univariate optimization showed that 5% (w/w) of NiZ and GO in the CP led to a threefold increase in peak current, decreased overpotential of paracetamol (PAR) oxidation, low background current, and high signal-to-noise ratio. The CPE/NiZ/GO sensor exhibited a linear response in the PAR concentration range of 0.004 to 0.12 mg L-1, with a low limit of detection of 0.0012 mg L-1 (0.0078 μM) and high stability (RSD = 3%). The proposed method demonstrated good selectivity and robustness to interference, and was successfully applied for the determination of PAR in pharmaceuticals, human urine, and serum.

Summary: A polymer-based carbon paste electrode was constructed using electropolymerized Alizarin Red S (ARS) film on the surface of the carbon paste electrode (CPE). The electrode's electrochemical properties were characterized using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), and its physical morphology was analyzed using scanning electron microscopy (SEM). The optimized electropolymerization cycles and supporting electrolyte resulted in the ability of poly-ARS/CPE to generate clear and distinguishable oxidation peaks for anthracene (ANT) and phenanthrene (PHE) during square wave voltammetry (SWV) in the presence of 0.1 M LiClO4 as a supporting electrolyte. The poly-ARS/CPE was successfully used for the detection of ANT and PHE in various water samples, demonstrating its selectivity, stability, and reproducibility.

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.
