Phosphorylation of Zearalenone Retains Its Toxicity.

Microbial biotransformation of Zearalenone (ZEN) is a promising deactivation approach. The residual toxicity and stability of Zearalenone-14-phosphate (ZEN-14-P) and Zearalenone-16-phosphate (ZEN-16-P), two novel microbial phosphorylation products of ZEN, remain unknown. We investigated the cytotoxicity, oxidative stress, proinflammatory, and estrogenic activity of phosphorylated ZENs using porcine intestinal cells, uterine explants, and human endometrial cells and traced their metabolic fate by liquid chromatography-tandem mass spectrometry (LC-MS)/MS analysis.

Li-Fraumeni-associated osteosarcomas: The French experience.

Purpose: Describe clinical characteristics and outcome of Li-Fraumeni syndrome (LFS)-associated osteosarcomas.

Methods: TP53 germline pathogenic/likely pathogenic variant carriers diagnosed with osteosarcoma in France between 1980 and 2019 were identified via the French Li-Fraumeni database at Rouen University Hospital. Sixty-five osteosarcomas in 52 patients with available clinical and histological data were included.

Potential of Non- Yeasts as Probiotics and Alternatives to Antibiotics in Animal Production.

Probiotics are live yeast or bacterial organisms that have beneficial effects on the host. Several microorganisms exhibit probiotic properties, the most common types being lactic acid bacteria, , spore-forming bacteria, and some yeast strains. var.

Insights into the genomic and phenotypic characteristics of spp. strains isolated from biofilms in broiler farms.

The characterization of surface microbiota living in biofilms within livestock buildings has been relatively unexplored, despite its potential impact on animal health. To enhance our understanding of these microbial communities, we characterized 11 spore-forming strains isolated from two commercial broiler chicken farms. Sequencing of the strains revealed them to belong to three species , , and .
