Development of blocking ELISA for detection anti-PRRSV antibodies and serological investigation of PRRSV in China.

Porcine reproductive and respiratory syndrome virus (PRRSV) demonstrates a significantly high prevalence among swine populations. Monoclonal antibodies (mAbs) with high affinity for conserved epitopes of PRRSV can facilitate the development of a broad-spectrum detection method for this virus. This study identified two PRRSV-specific mAbs, designated 2B1 and 2C6, which recognized two conformation-dependent epitopes through indirect immunofluorescence assay (IFA) and Western blot analysis.

CMCS-PVA@CA hydrogel dressing: A promoter of wound healing with MRSA virulence attenuation function.

Traditional wound dressings, primarily centered on antimicrobial or bactericidal strategies, have inadvertently contributed to the rise of drug-resistant bacterial colonies at wound sites, thus prolonging the healing process. In this study, we developed an innovative hydrogel dressing, CMCS-PVA@CA, incorporating carboxymethyl chitosan (CMCS), polyvinyl alcohol (PVA), and cichoric acid (CA), specifically designed to treat skin wounds infected with methicillin-resistant Staphylococcus aureus (MRSA). Computational biology analyses reveal that CA exerts substantial anti-virulence activity by targeting serine/threonine phosphatase (Stp1), achieving an IC of 3.

Construction of GOx-loaded metal organic frameworks antibacterial composite hydrogels for skin wound healing.

Bacterial infections and inflammation severely impede wound healing. Here, we developed a zwitterionic hydrogel incorporating MOF/GOx for pH-responsive, controlled drug release. The multifunctional hydrogel embedded with MOF/GOx was successfully prepared through the Schiff base reaction between the copolymer poly[(2-methacryloyloxyethyl phosphorylcholine)-co-(4-formylphenyl methacrylate)] (PMF) and the branched polyethylenimine (PEI) modified by the zwitterionic monomer ((4-hydroxyphenyl)sulfonyl)(4-(trimethylammonio)butanoyl)amide (AB), which possessed excellent injectable and self-healing ability, a highly sensitive and reversible responsiveness to pH changes, and good biocompatibility.

The major roles of intestinal microbiota and TRAF6/NF-κB signaling pathway in acute intestinal inflammation in mice, and the improvement effect by Hippophae rhamnoides polysaccharide.

Acute enteritis, an intestinal disease with intestinal inflammation and injury as the main pathological manifestations.

Unraveling the Peripheral Nervous System's Role in Tumor: A Double-edged Sword.

The peripheral nervous system (PNS) includes all nerves outside the brain and spinal cord, comprising various cells like neurons and glial cells, such as schwann and satellite cells. The PNS is increasingly recognized for its bidirectional interactions with tumors, exhibiting both pro- and anti-tumor effects. Our review delves into the complex mechanisms underlying these interactions, highlighting recent findings that challenge the conventional understanding of PNS's role in tumorigenesis.

Toward one-step As(III) removal in ultrafiltration with in situ BioMnO cake layer: Mechanism and feasibility insights.

Inorganic arsenic (As) is one of the most significant chemical contaminants in drinking water worldwide. Although membrane-based technologies are commonly used for As removal, they often encounter challenges including complex operation, high energy consumption, and the need for chemical addition. To address these challenges, we proposed a one-step ultrafiltration (UF) process empowered by in situ biogenic manganese oxides (BioMnO) cake layers without any additional chemicals, to treat source water contaminated with both As and manganese (Mn).

Flat membrane-based liquid-phase microextraction for the determination of basic and acidic pesticide residues in water samples.

A flat membrane-based liquid-phase microextraction (FM-LPME) method was developed for the first time to simultaneously separate and extract basic and acidic pesticide analytes from the same sample. Using carbendazim and pirimicarb as representative basic pesticides, along with bromacil, diflubenzuron and 1,2-dibenzoyl-1‑tert-butylhydrazine (RH-5849) as representative acidic pesticides, the performance of FM-LPME for the extraction of these model pesticides has been optimised individually. Under optimal extraction conditions, the developed FM-LPME-LC-MS/MS method exhibited excellent linearity, with R values exceeding 0.
