Summary: This study investigated the effects of L.plantarum strains with antioxidation properties on the quality of fermented sausage. The results showed that these strains were able to reduce lipid and protein oxidation during fermentation, as well as enhance the production of flavor substances. These findings suggest that L.plantarum strains with antioxidation properties have potential applications in maintaining the stability of sausage quality and improving flavor.

Summary: The study demonstrated that Lactobacillus pentosus R3 effectively reduces N-nitrosodimethylamine (NDMA) content in fermented sausages through various mechanisms, including direct degradation, indirect reduction of precursors, weakened oxidation, and decrease in non-haem iron content. This is achieved by inoculating the sausages with L. pentosus, which also improves microbial quality and inhibits NDMA formation.

Summary: Cytoglobin (Cygb) has potent superoxide dismutase (SOD) function, rapidly dismutating superoxide in cells to protect against oxidative stress. Its role in cellular superoxide metabolism is important due to its ubiquitous expression in cells at micromolar concentrations.

Summary: One of the most critical challenges in applying amine-based CO2 adsorbents on a large scale is their long-term stability and oxidative degradation. In this study, the oxidation of polyethylenimine (PEI) was investigated using various analysis techniques, and the presence of radical species and their increase in the presence of transition metal catalysts were observed for the first time. Significant amounts of CO2, water, and ammonia were also detected. Surprisingly, although epoxybutane (EB) and polyvinyl alcohol (PVA) improved the oxidation resistance of PEI, they did not reduce the amount of radical species. Theoretical calculations suggested that PEI is more prone to oxidation due to its weaker C-H bonds. The findings provide insights into the oxidation and antioxidation mechanisms of amines and offer clues for further improvement.

Summary: The study demonstrates that Fe(II)/PAA system can effectively remove diclofenac sodium in neutral condition, with removal rate influenced by operational parameters. Natural organic matter has a negative impact on DCF degradation, and multiple degradation pathways may exist based on detected reaction products.

Summary: We have successfully synthesized an optical nanoprode (Ag0-pullulan-Ag+) for sensitive and selective detection of ferrous ions (Fe2+) in solution over ferric ions (Fe3+). The nanoprode, made of pullulan biopolymer and silver nanoparticles (AgNPs), showed a sharp absorption peak at 415 nm and a size distribution of 20-30 nm. By reducing available Ag+ to more AgNPs, it exhibited a colorimetric response from light yellow to brownish yellow upon the addition of Fe2+. The detection of Fe2+ was linear within the range of 1.0-20.0 and 20.0-125.0 mM, with a limit of detection (LOD) of 0.15 mM. Our work demonstrates the potential of carefully synthesized nanomaterials for sensitive and accurate analyte sensing.

Summary: Rational design of metallic active sites and its microenvironment is critical for constructing superoxide dismutase (SOD) nanozymes. Here, a novel SOD nanozyme design was reported, using graphene oxide (GO) as the framework and delta-MnO2 as the active sites to mimic natural Mn-SOD. The nanozyme achieved superlative SOD-like catalytic performance with a 95.5% inhibition rate, which is significantly higher than GO and MnO2 nanoparticles.

Summary: In this study, metabolites in Shenheling (SHL) fermented by Lactobacillus fermentum were analyzed using UHPLC-QE-MS. A total of 102 differential metabolites in nine categories were identified before and after fermentation, including alkaloids, organic acids, and flavonoids. After fermentation, the contents of several metabolites associated with antioxidation, anti-obesity, hypoglycemic, antibacterial, and improved immunity effects were increased. KEGG pathway analysis revealed important metabolic pathways affected by fermentation.

Summary: The study synthesized PC-PSPANBs to control persulfate release for targeted PAHs' degradation, showing significantly slower release rate with polystyrene coating. The Fe(II)-activated PC-PSPANBs achieved high removal efficiencies and degradation rate constants for ACE, 2-MN, and DBF, while the presence of anions SO42- and Cl- enhanced the degradation. The effectiveness of PS release longevity was demonstrated with sustained degradation of ACE and DBF even after repeated spiking.

Summary: This study investigated the effects of different levels of beta-hydroxy-methylbutyrate (HMB) in the diet on the fatty acid and amino acid compositions, and lipid metabolism in broiler chickens. The results showed that 0.10% HMB supplementation had a beneficial effect on lipogenesis in the breast muscle, while 0.05% and 0.15% HMB supplementation decreased lipogenesis and meat nutritional values in the leg muscles.
