Discovery of novel benzo[b][1,4]oxazine derivatives as ferroptosis inhibitors.

Ferroptosis is a novel type of programmed cell death characterized by radical-driven lipid peroxidation accumulation, which is involved in various diseases, including acute organ injury and neurodegenerative disorders. Pharmacological inhibition of ferroptosis is a promising strategy for treating these diseases. In this study, 16 benzo[b][1,4]oxazine derivatives were synthesized and assayed for their antiferroptotic activity.

Effects of Supplementation on Growth Performance, Hepatic Lipid Metabolism, and mRNA Expression of Lipid Metabolism Genes and Intestinal Flora in Geese.

The effects of () at a concentration of 1.0 × 10 CFU/mL on growth performance, hepatic lipid metabolism, and mRNA expression related to lipid metabolism, intestinal morphology, and intestinal flora were investigated in geese. A total of 60 male geese, aged 30 days and of similar weight, were randomly assigned to 2 groups.

Isolation and Evaluation of Strains from Traditional Rice Wine Starters (): Enzyme Activities, Antioxidant Capacity, and Flavour Compounds.

Seventy-eight autochthonous strains of were isolated from rice wine starter samples across twenty-nine regions in China to evaluate their potential in traditional rice wine fermentation. Strains were assessed for enzyme activity, antioxidant properties, amino acid production, and volatile flavour compounds. Significant variation in enzyme activities was observed, with acidic protease activity ranging from 280 to 1023 U/g, amylase from 557 to 1681 U/g, and esterase from 370 to 2949 U/g.

Deformation behavior of additive manufactured 316 L stainless steel using in situ neutron diffraction.

Manufacturing of metallic components using additive manufacturing technique is of great interest for the industrial applications. Here, the mechanical and microstructural responses of a 316 L stainless steel (316LSS) built by selective laser melting (SLM) with XOY and XOZ directions were revealed by performing in situ neutron diffraction tensile tests. The tensile strength of the XOY-printed samples reaches 700 MPa, while the tensile strength of the XOZ-printed samples is less than 600 MPa.

Dual effects of exogenous ferulic acid bound in rice starch as 3D printable food ink: Structural fluidity and antimicrobial activity.

Starch-ferulic acid (FA) composites have been developed for medical and food fields, while little focus is caused on their use in functional products by 3D printing. In this work, dynamic high-pressure microfluidization was employed to treat starch at various concentrations, for preparing modified starch-FA composites. The high-performance liquid chromatography results showed that an increased starch concentration was conducive to a high yield of composite with enhanced binding of FA.
