Abstract

We present a simple drop-casting method for preparing multiferroic nano-composite film where BiFeO3 (BFO) nanoparticles (NPs) were evenly dispersed into polyvinyl alcohol (PVA) polymer. BFO NPs used in this work were synthesized by the conventional sol-gel method, having diameter of tens of nm and being in good crystallinity. The BFO NPs were loaded into a highly insulating PVA polymer solution as filler. The multiferroic properties of the film reveal ferromagnetic ordering due to the uncompensated spiral ordering and saturated ferroelectric curves due to the cut-off of current leakage. Moreover, the prepared films show high flexibility and their multiferroicities are preserved well even in a high curved condition, reflecting the possibility for fabricating wearable devices based on multiferroic materials.

Abstract

In this study, a novel antimicrobial peptide, scolopendin 1, was identified from adult centipedes, Scolopendra subspinipes mutilans using RNA sequencing. Scolopendin 1 exerted an antimicrobial activity without inducing haemolysis of human erythrocytes. In order to understand the antifungal mechanism, a reactive oxygen species ( ROS) assay was performed, which indicated that scolopendin 1 induced ROS accumulation in Candida albicans. Evaluation of fungal viability using N-acetyl cysteine, a ROS scavenger, suggested that ROS are a major factor in scolopendin 1-induced fungal cell death. Co-staining of annexin V-fluorescein isothiocyanate ( FITC) and propidium iodide, and TUNEL and 4′,6-diamidino-2-phenylindole ( DAPI) assays confirmed that ROS-induced fungal cell death is associated with apoptosis. To further investigate the mechanism that facilitates the progression of apoptosis, changes in intracellular Ca2+ concentration and mitochondrial dysfunction were examined. Ca2+, a signalling molecule in the apoptotic pathway, was increased in the cytosol and mitochondria, and ROS accumulation triggered mitochondrial depolarization and the release of cytochrome c, a pro-apoptotic factor, from the mitochondria to the cytosol. Finally, the released cytochrome c activated intracellular caspase. The present study suggests that scolopendin 1 could emerge as a model molecule that targets the apoptotic pathway and provides a novel remedy. [ABSTRACT FROM AUTHOR]
