The antioxidants butylated hydroxytoluene (BHT) and ethoxyquin protected rats against intoxication and mortality normally produced by hexachlorophene (HCP, 100 mg/kg). BHT also prevented the elevation of cerebrospinal fluid pressure, a central nervous system effect of HCP poisoning. In addition, both phenobarbital and SKF-525A protected against HCP poisoning, with the barbiturate also offering significant protection against triethyltin. L-Ascorbic acid, vitamin E, N,N-diphenyl-p-phenylenediamine and reduced and oxidized glutathione over a range of doses were ineffective in preventing HCP lethality. The protective effect of phenobarbital against HCP and triethyltin intoxication further supports existing evidence of a common or similar mechanism of toxic action for these two structurally dissimilar compounds.

This study successfully synthesised and characterised composites combining chitosan (CH), carboxymethyl cellulose (CMC), and various flavonoids (Fla). This innovative approach demonstrates the potential for developing functional materials with antioxidant and food preservation properties. The composites CH-Fla-CMC (1-5) was characterised using advanced techniques such as FT-IR, UV-Vis, XRD, SEM, TEM, and TGA, providing robust data on their structural, morphological, and thermal properties.

The additive is already authorised as zootechnical feed additive for breeder hens.

Introduction: This study aimed to understand the origin and to explain the maintenance of extended-spectrum β-lactamase (ESBL) isolated from food-producing animals in a third-generation cephalosporin (3GC)-free farm.
Methods: Culture and molecular approaches were used to test molecules other than 3GC such as antibiotics (tetracycline and oxytetracycline), antiparasitics (ivermectin, flumethrin, fenbendazol, and amitraz), heavy metal [arsenic, HNO, aluminum, HNO, cadmium (CdSO), zinc (ZnCl), copper (CuSO), iron (FeCl), and aluminum (AlSO)], and antioxidant (butylated hydroxytoluene) as sources of selective pressure. Whole-genome sequencing using short read (Illumina™) and long read (Nanopore™) technologies was performed on 34 genomes.

() utilizes heme as an iron source from the host during infection. Biliverdin beta and delta (BVIXβ and BVIXδ) are generated by HemO, specific to , while biliverdin alpha is generated from the bacterial BphO system and by mammalian heme oxygenases. Here, we have developed and characterized a quantitative LC-MS/MS assay for the separation of three endogenous isomers, BVIXα, BVIXβ, and BVIXδ.
