    Abstract The bioactive peptides and trace element selenium (Se) both have good antioxidant activity. However, whether combined Se and bioactive peptides have more excellent antioxidant activity remain unknown. The aim of this study is to prepare a Se-rich peptide fraction containing both Se and peptides from Se-rich yeast protein hydrolysate and investigated its antioxidant activity and effect on ultraviolet B (UVB) radiation-induced skin oxidative damage. The peptide fractions with different molecular weight (MW) and Se content were obtained by enzymatically hydrolyzing normal or Se-rich yeast proteins followed by a filtration process. In vitro free radical scavenging and lipid peroxidation inhibition assays showed that Se-rich peptides fraction with lower MW of <1 kDa (sSeP) had the highest antioxidant activity compared with Se-rich peptide fractions with higher MW of <3 kDa or normal peptide fractions. Oral administration of sSeP significantly decreased the level of malonaldehyde (MDA) in liver and serum, and increased the activity of glutathione peroxidase (GPx) in liver and serum in normal mice. When topically applied on the dorsal skin of mice, sSeP effectively alleviate UVB radiation-induced skin damage and oxidative stress by increasing GPx and catalase activities and glutathione content in skin or serum. Furthermore, sSeP showed a protective effect against H

    Abstract Bioaccumulation of nanoplastic particles has drawn increasing attention regarding environmental sustainability and biosafety. How nanoplastic particles interact with the cellular milieu still remains elusive. Herein, we exemplify a general approach to profile the composition of a "protein corona" interacting with nanoparticles via the photocatalytic protein proximity labeling method. To enable photocatalytic proximity labeling of the proteome interacting with particles, iodine-substituted BODIPY (I-BODIPY) is selected as the photosensitizer and covalently conjugated onto amino-polystyrene nanoparticles as a model system. Next, selective proximity labeling of interacting proteins is demonstrated using I-BODIPY-labeled nanoplastic particles in both

    Abstract The new porcine epidemic diarrhea (PED) has caused devastating economic losses to the swine industry worldwide. Despite extensive research on the relationship between autophagy and virus infection, the concrete role of autophagy in porcine epidemic diarrhea virus (PEDV) infection has not been reported. In this study, autophagy was demonstrated to be triggered by the effective replication of PEDV through transmission electron microscopy, confocal microscopy, and Western blot analysis. Moreover, autophagy was confirmed to benefit PEDV replication by using autophagy regulators and RNA interference. Furthermore, autophagy might be associated with the expression of inflammatory cytokines and have a positive feedback loop with the NF-κB signaling pathway during PEDV infection. This work is the first attempt to explore the complex interplay between autophagy and PEDV infection. Our findings might accelerate our understanding of the pathogenesis of PEDV infection and provide new insights into the development of effective therapeutic strategies.
