Magnetic Pinecone Biochar‐Activated Peroxymonosulfate for Efficient Sulfamethoxazole Degradation: Performance, Mechanism, and Toxicity Analysis

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study successfully prepared magnetic iron/cobalt codoped biochar catalyst (CFSBC) using a one‐step calcination method. The morphology and structure of the material were systematically characterized using SEM, XRD, FTIR, TEM, BET, Raman, VSM, and XPS techniques. The effects of key parameters such as catalyst dosage, peroxymonosulfate (PMS)

Emergence of Staphylococcus aureus Resistance to Antimicrobial Peptides Nisin, NZ2114 and Bacitracin Involves Multiple Phenotypic Changes

Animal Research and One Health, EarlyView.
The AMP‐induced mutant Staphylococcus aureus strain nzR showed increased resistance, five gene mutations, and decreased surface anion levels. AMPs affect the NDH‐2 protein encoded by ndh gene inhibiting the growth of S. aureus. The deletion of the ndh gene promotes the development of AMPs resistance.

Dietary Baicalin Supplementation Can Enhance the Growth Performance of Weaned Piglets and Maintain the Intestinal Barrier Integrity

Animal Research and One Health, EarlyView.
This research innovatively illustrates baicalin’s multifaceted mechanisms in enhancing piglets’ intestinal health: modulating bile acid metabolism via probiotics, reinforcing tight junction proteins (ZO‐1/claudin), suppressing TLR4/NF‐κB‐mediated inflammation, whereas promoting growth and reducing diarrhea.

Multi‐Omics Insights Into the Role of Fructooligosaccharides Supplementation in Alleviating Salpingitis in Laying Hens

Animal Research and One Health, EarlyView.
Multi‐omics analysis revealed that FOS supplementation increased the abundance of Phascolarctobacterium, GCA‐900066575, Shuttleworthia, Olsenella, Eubacterium_hallii_group while decreasing Alistipes. It also influenced the metabolism of S‐lactoylglutathione, p‐cresol glucuronate, 2‐phenylethanol glucuronide, propionic acid, dulcitol, and inhibited the ...
