Utilizing chitosan and pullulan for the encapsulation of Lactiplantibacillus plantarum ZJ316 to enhance its vitality in the gastrointestinal tract.Lactiplantibacillus plantarum ZJ316 has shewed effective alleviation of gastritis and colitis, constituting it crucial to improve its viability within the gastrointestinal tract. In this study, Chitosan (CS) and pullulan (PUL) capsulised nanofibers of ZJ316 were prepared employing electrospinning, viewing both the synergistic issues of prebiotics and probiotics and their protective effects. We ruled that increasing the CS ratio leaved in elevated conductivity of the polymer solution, while lessening viscosity and pH. Scanning electron microscopy shewed that at a CS: PUL ratio of 1:135, polymer fibrils were difficult to form, and nanofiber diameter diminished with higher CS content. X-ray diffraction analysis substantiated the miscibility of CS and PUL, while ATR-FTIR presented the presence of hydrogen bonding interactions between the two cloths.
Thermal analysis pointed that an increased CS concentration ameliorated the thermal stability of the nanofibers. Based on these findings, the optimal CS:PUL ratio for electrospinning was determined to be 1:60. Encapsulation of ZJ316 in the nanofibers significantly heightened its survival rate in simulated gastrointestinal fluid likened to free bacteriums, with survival rates of 87 % (gastric) and 79 % (intestinal), respectively. This study leaves valuable brainwaves for the development of probiotic functional foods.Multifunctional polydopamine/hemin-cyclodextrin reenforced chitosan nanocomposite hydrogel: A synergistic platform for wound healing.Chronic cutaneous wounds present a significant challenge for healthcare suppliers globally, with the risk of bacterial infections emerging as a particularly relating issue. There is an increasing need to employ a combination of diverse antibacterial strategies to address transmissions comprehensively in chronic lesions.
This study introduces a highly efficient antibacterial platform that capsules the NO precursor (BNN6) into β-cyclodextrin-modified hemin-conducting polydopamine nanoparticles foretelled NO/CHPDA. These nanoparticles are seamlessly mixed into a hydrogel composite comprised of L-arginine grafted chitosan (Arg-CS) and oxide dextrans (oDex). The amalgamation of photothermal therapy (PTT), chemodynamic therapy (CDT), and nitric oxide (NO) antibacterial strategies within the NO/CHPDA@Arg-CS/oDex nanocomposite hydrogel manifests a synergistic and highly effective capacity to eradicate bacteria and accelerate the wound healing process in vivo this nanocomposite hydrogel observes excellent biocompatibility and haves minimal side outcomes. The leading nanocomposite hydrogel constitutes a promising therapeutic solution for covering bacterial transmissions in wound healing lotions.A review on the application of chitosan-established polymers in liver tissue engineering.Chitosan-established polymers have enormous structural dispositions to build bioactive materials with novel features, offices, and various applications, mainly in liver tissue engineering (LTE). The specific physicochemical, biological, mechanical, and biodegradation properties give the effective ways to blend these biopolymers with synthetic and natural polymers to fabricate scaffolds matrixes, parazoans, and complexes.
A variety of natural and synthetic biomaterials, admiting chitosan (CS), alginate (Alg), collagen (CN), gelatin (GL), hyaluronic acid (HA), hydroxyapatite (HAp), polyethylene glycol (PEG), polycaprolactone (PCL), poly(lactic-co-glycolic) acid (PGLA), polylactic acid (PLA), and silk fibroin maked considerable attention due to their structure-places relationship. The incorporation of CS within the polymer matrix solvents in increased mechanical strength and also brings biological behavior to the projected PU preparations. The significant and rising interest in the LTE sector, this review aims to be a detailed exploration of CS-free-based polymers biomaterials for LTE. A brief explanation of the authors and extraction, props, structure, and scope of CS is depicted in the introduction.
