The efficient and regenerable antibacterial properties of Nhalamines make them an ideal candidate for parapretion of antimicrobial textiles. In this study,a 5,5-dimethylhydantoin-based reactive N-halamine precursor, 4-( 4-( 3-( 3-hydroxypropyl)-5,5-dimethylhydantoin)-6-chloro-1,3,5-triazinylamino)-benzenesulfonate( HTB), was synthesized and characterized by ~1H-NMR. The synthesized compound was coated to cotton fabrics via reactive dye dyeing process. The coated cotton showed excellent antimicrobial activities against S. aureus( Gram-positive) and E. coli O157: H7( Gram-negative) with short contact times after exposing to diluted household bleach. The treatment method used in this study has a small effect on the tensile strength of cotton fabrics. The durability and regenerability of the chlorinated cotton samples were *** the chlorine content decreased towards washing and storage,almost all of the initial oxidative chlorine levels could be regained after rechlorination.

Three dimensional（3D） bioprinting, which involves depositing bioinks（mixed biomaterials） layer by layer to form computer-aided designs, is an ideal method for fabricating complex 3D biological structures. However, it remains challenging to prepare biomaterials with micro-nanostructures that accurately mimic the nanostructural features of natural tissues. A novel nanotechnological tool, electrospinning, permits the processing and modification of proper nanoscale biomaterials to enhance neural cell adhesion, migration, proliferation, differentiation, and subsequent nerve regeneration. The composite scaffold was prepared by combining 3D bioprinting with subsequent electrochemical deposition of polypyrrole and electrospinning of silk fibroin to form a composite polypyrrole/silk fibroin scaffold. Fourier transform infrared spectroscopy was used to analyze scaffold composition. The surface morphology of the scaffold was observed by light microscopy and scanning electron microscopy. A digital multimeter was used to measure the resistivity of prepared scaffolds. Light microscopy was applied to observe the surface morphology of scaffolds immersed in water or Dulbecco＇s Modified Eagle＇s Medium at 37℃ for 30 days to assess stability. Results showed characteristic peaks of polypyrrole and silk fibroin in the synthesized conductive polypyrrole/silk fibroin scaffold, as well as the structure of the electrospun nanofiber layer on the surface. The electrical conductivity was 1 × 10^-5–1 × 10^-3 S/cm, while stability was 66.67%. A 3-（4,5-dimethyl-2-thiazolyl）-2,5-diphenyl-2-H-tetrazolium bromide assay was employed to measure scaffold cytotoxicity in vitro. Fluorescence microscopy was used to observe Ed U-labeled Schwann cells to quantify cell proliferation. Immunohistochemistry was utilized to detect S100β immunoreactivity, while scanning electron microscopy was applied to observe the morphology of adherent Schwann cells. Results demonstrated that the polypyrrole/silk fibroin scaffo

In order to improve the stabilization and spinnability of polyacrylonitrile, a bifunctional comonomer containing both ester and amide groups was synthesized to prepare poly（acrylonitrile-co-3- aminocarbonyl-3-butenoic acid methyl ester） [P（AN-co-ABM）] copolymers used as the carbon fiber precursor instead of poly（acrylonitrile-acrylamide-methyl acrylate） [P（AN-AM-MA）] terpolymer. The differential scanning calorimetry and thermogravimetry results show that the stabilization of P（AN-co- ABM） have been remarkably improved by ABM compared with P（AN-AM-MA） terpolymer, such as lower initiation temperature, broadened exothermic peak and smaller activation energy. Moreover, the spinnability of P（AN-co-ABM） is also improved by ABM due to the lubrication of ester groups in ABM. This study clearly shows that P（AN-co-ABM） copolymer is a better material for use as a carbon fiber precursor than P（AN-AM-MA） terpolymer.

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

Great efforts have been devoted to improve the photocatalytic activity of TiO2 in the visible light region. Rational design of the external structure and adjustment of intrinsic electronic status by impurity doping are two main effective ways to achieve this purpose. A facile onepot synthetic approach was developed to prepare C-doped hollow TiO2 spheres, which simultaneously realized these advantages. The synthesized TiO2 exhibits a mesoporous hollow spherical structure composed of fine nanocrystals, leading to high specific surface area（~180 m^2/g） and versatile porous texture. Carbonate-doping was achieved by a postthermal treatment at a relatively low temperature（200°C）, which makes the absorption edge red-shifted to the visible region of the solar spectrum. Concomitantly, Ti^（3＋） induced by C-doping also functions in improving the visible-light photocatalytic activity by reducing the band gap. There exists a synergistic effect from multiple stimulatives to enhance the photocatalytic effect of the prepared TiO2 catalyst. It is not out of expectation that the asprepared C-doped hollow TiO2 spheres exhibits an improved photocatalytic activity under visible light irradiation in organic pollutant degradation.
