Despite the development of numerous antibiotics, the continuous rise of drug-resistant bacteria highlights the urgent need for new materials to combat these problems. In this study, four water-soluble quaternized cellulose (QC) derivatives with degrees of substitution (DS) ranging from 0.23 to 0.45 were synthesized homogeneously from cellulose carbamate (CC) in NaOH/ZnO aqueous solution. The QC derivatives exhibited broad-spectrum antibacterial activity against gram-negative/positive bacteria, fungi and drug-resistance bacteria. Models of bacterial vaginitis (BV) and vulvovaginal candidiasis (VVC) were used to evaluate the application of QC derivatives visually. Secretion smears and tissue section staining revealed that treatment with QC derivatives led to a reduction in mycelia and spores in the vagina and secretions in the VVC model, along with improved inflammation. In the BV model, vaginal secretions were reduced, clue cells in smears significantly decreased, and inflammation markedly improved. Additionally, cell experiments and staining of mouse organ tissue sections demonstrated that QC derivatives exhibited good biocompatibility. Therefore, using QC derivatives in flushing douches represents a novel approach for treating vaginitis and could serve as a benchmark for addressing other infectious diseases.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"349 ","pages":"Article 122950"},"PeriodicalIF":10.7,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study developed a temperature-responsive gating chitosan-based microcapsule (CTSMC-g-PNIPAM) by grafting N-isopropyl acrylamide (NIPAM) onto chitosan microcapsules (CTSMC) via atom transfer radical polymerization (ATRP). The interfacial crosslinking of chitosan (CTS) and terephthalendehyde (TPA) formed the CTSMC matrix with a hollow chamber structure and ensured stability. CTSMC-g-PNIPAM exhibited reversible temperature-responsive gating properties and sustained release behavior, and the PNIPAM chains acted like gating switches. Below the low critical solution temperature (LCST) (25 °C), the PNIPAM chains stretched and the gating switch closed, slowing down the release rate. Above the LCST (40 °C), the PNIPAM chains contracted and the gating switch opened, accelerating the release rate. The release behaviors of CTSMC-g-PNIPAM in soil indicated that the gating microcapsule effectively prolonged the release of urea. Moreover, the cumulative release of CTSMC-g-PNIPAM at 40 °C was significantly higher than at 25 °C. The first-order kinetic and Korsmeyer-Peppas model indicate that the urea release involves concentration gradient diffusion and skeleton dissolution.

The emulsions had the best stability when the pH was 4 and the concentration of OVA particles was 3 %. Moreover, since ovalbumin fibril (OVAF) had better adsorption at the water-water interface than ovalbumin sphere (OVAS), OVAF-stabilized TG/AMP emulsion (OF-TE) had a relatively denser interfacial layer and exhibited more satisfactory ionic stability and physical stability than OVAS-stabilized TG/AMP emulsion (OS-TE). The rheological results demonstrated that OVAF and OVAS had little effect on the viscosity of TG/AMP emulsions. In brief, OVAF was more effective in improving the stability of TG/AMP emulsions than OVAS, and OF-TE did not show phase separation for at least 5 days.
