Magnetic molecular imprinted covalent organic framework composite for the magnetic solid-phase extraction of bisphenol AF.

A magnetic molecular imprinted covalent organic framework composite (MCOF-MIP) that possessed the 'dual-selectivity' of a covalent organic framework and molecular imprinted polymer (MIP) with rapid response performance was successfully prepared for the removal of bisphenol AF (BPAF) from real water and blood samples.

The MCOF showed high crystallinity and good adsorption capacities for BPAF (107.

ZnS/CuFeO/MXene ternary heterostructure photocatalyst for efficient adsorption and photocatalytic degradation of azo dyes under visible light: Synergistic effect, mechanism, and application.

ZnS/CuFeO/MXene (ZSCFOM) composite with ternary heterostructures was prepared by solvothermal methods for the first time to effectively adsorb and photodegrade the azo dyes. ZSCFOM mainly adsorbed azo dyes through the hydrogen bonding and electrostatic interactions, with saturated adsorption capacities of 377 mg g for direct brown M and 390 mg g for direct black RN. ZSCFOM exhibited both characteristics of Schott heterostructure and p-n heterostructure, but it is not a simple superposition of the two heterostructures, but rather achieves better photocatalytic property.

Carbonized human hair derived carbon dots for detection of clozapine.

Fabrication of highly crystalline covalent organic framework for solid-phase extraction of three dyes from food and water samples.

Herein, a covalent organic framework, which was fabricated at room temperature by using 1,3,5-tris(p-formylphenyl) benzene and 1,3,5-tris(4-aminophenyl)benzene as building blocks, was employed as an adsorbent for solid-phase extraction of dyes including congo red, methyl blue and direct red 80 for the first time. The prepared covalent organic framework was properly characterized by different techniques and the results revealed that it had a uniform spherical structure, high crystallinity, satisfactory surface area, and good thermal stability.

Effects of Selected Resveratrol Analogues on Activation and Polarization of Lipopolysaccharide-Stimulated BV-2 Microglial Cells.

Increasing health-promoting effects of resveratrol and its molecular structural analogues have been discovered, and the acting mechanism has been explored. However, the activity comparison of such compounds in targeting macrophage-related inflammation associated with neurodegenerative diseases remains untouched. In this study, we evaluated the activation and polarization transition of lipopolysaccharide (LPS)-stimulated BV-2 mouse microglial macrophages exposed to resveratrol (RES) and its analogues pterostilbene (PTE), oxyresveratrol (ORES), acetyl--resveratrol (ARES), and -2,3,5,4'-tetrahydroxystilbene-2-O-glucopyranoside (TSG).

Protective effect of pterostilbene on concanavalin A-induced acute liver injury.

Pterostilbene (PTE) is broadly found in berries and has antioxidant and anti-inflammatory properties. To examine the effect of PTE on acute liver injury, mice were administrated PTE prior to concanavalin A (ConA).

Effect of ultrasound-assisted extraction on physicochemical properties and TLR2-affinity binding of the polysaccharides from Pholiota nameko.

The effect of the ultrasonic treatment on the physicochemical properties, oil-holding capacities, foaming capacities, and TLR2-affinity of the polysaccharides from Pholiota nameko (PNPS), was evaluated. Compared with the protein content of PNPS before ultrasonic treatment, the protein content of PNPS all presented a decrease under different ultrasonic conditions. The viscosity of PNPS showed a decrease when the ultrasonic intensity was strong enough, as well as the molecular weight.

Effects of Pholiota nameko polysaccharide on NF-κB pathway of murine bone marrow-derived dendritic cells.

This study investigated the effect of a polysaccharide purified from Pholiota nameko (PNPS-1) on the NF-κB signaling pathway of murine bone marrow-derived dendritic cells (BMDCs) and relevant mechanisms. The results showed that PNPS-1 could decrease the expression of maturation markers CD40 and CD80 on BMDCs.

This paper recognized the affinity bind between PNPS and the five receptors (TLR2, TLR4, CD14, Dectin-1 and Mannose receptor) on BMDCs, using the bio-layer interferometry (BLI)-based biosensor technology developed by ForteBio on Octet RED system (Fortebio, Inc.).

Effects of polysaccharides from Pholiota nameko on maturation of murine bone marrow-derived dendritic cells.

This paper studied some structure characters of the Pholiota nameko polysaccharides (PNPS-1), including morphology under SEM and AFM, also the effects of PNPS-1 on the maturation of bone marrow dendritic cells (BMDCs) via concrete changes both inside and outside BMDCs. These impacts on BMDCs were assessed with use of inverted phase contrast microscope for morphology, flow cytometry for key surface molecules, mixed lymphocyte reaction (MLR) for allogeneic T cells proliferation, and bio-assay and enzyme linked immunosorbent assay (ELISA) for cytokine production. We found that PNPS-1 could inhibit phenotypic maturation as evidenced by decreasing expression of CD11c, CD40, CD80, CD83, CD86, and I-A/I-E.
