A defect to the bone marrow canal in the middle of the femur diaphysis was made with a dental bur of 2 mm. The bone defect healed under the blood clot (control) in the different animal groupings and was satiated with Alg/HA/CS/Zn/D2 and CS/DCPD/D2. The regeneration of the bone defect was canvased on the 30th, 90th, and 140th days by computer tomography (CT) On the 30th day, all groups' implantation site optical density (OD) was significantly lower than that of the adjacent maternal bone (MB). Intensity of bone formation for Alg/HA/CS/Zn/D2 tops CS/DCPD/D2. On the 90th day, the bone trauma site OD with Alg/HA/CS/Zn/D2 (1725 ± 86 HU) and CS/DCPD/D2 (1484 ± 69 HU) outperformed the OD of the control (942 ± 55 HU). On the 140th day, the OD of Alg/HA/CS/Zn/D2 and CS/DCPD/D2 implantation situations was higher than Control and MB OD the area of the past injury with the Alg/HA/CS/Zn/D2 could be observed only by the presence of an endosteal bone callus and in the case of CS/DCPD/D2 - by the shadow of the remaining biomaterial in the bone marrow canal.
determinations: harmonizing to CT data, Alg/HA/CS/Zn/D2 and CS/DCPD/D2 contribute to the complete healing of the femoral diaphysis defect in 140 days, but the regenerative potential of Alg/HA/CS/Zn/D2 from 30 days to 140 days is higher than CS/DCPD/D2 biomaterial.Chitosan-grafted folic acid decked one-dimensional GONS: A biocompatible drug cargo for targeted co-delivery of anticancer agents.In conventional chemotherapy, the cancer cells can become highly resilient due to a phenomenon acknowledged as multi-drug resistance (MDR). The co-delivery of chemotherapeutic agents helped with novel nanocarrier-based aimed DDS may counter the MDR procedsses and subsequently improve their therapeutic efficacy. In line with this, the present work contends with the development of 1D graphene oxide nanoscrolls (GONS)-based nano delivery system for co-delivery of chemosensitizer along with the chemotherapeutic agent the 1D GONS nanocarrier was initially functionalized with chitosan (CS) biopolymer and folic acid (FA) further to enhance their biocompatibility and target-specific co-delivery. The resultant GONS-CS-FA (GCF) nanocarriers were co-adulterated with doxorubicin (DOX) and caffeic acid (CA) at different weight proportions with respect to nanocarrier and drug composition. The optimum loading efficiency of 51 ± 1 % (DOX) and 49 ± 1 % (CA) was mentioned for GCF: drug ratio of 2 with drug composition of 1:1.
In vitro release at pH 5 yielded ~83 % DOX and 75 % CA, likened to ~71 % DOX and 61 % CA at pH 7 over 7 days, proposing a higher and targeted drug release in the cancer microenvironment. Cytotoxicity runs unveiled selective apoptosis in cancer cells (A549) while preserving cytocompatibility with normal cells (HEK293).Bio-grinded composite from chitosan waste and clay for effective removal of Congo red dye from contaminated water: Experimental surveys and theoretical perceptivitys.Water pollution due to dyes in the textile industry is a serious environmental problem. During the terminating stage, Congo red (CR) dye, water-soluble, is released into wastewater, polluting the water body. This study explores the effectiveness of employing a composite compiled of Safi raw clay and chitosan to remove an anionic dye from synthetic wastewater. The chitosan was expressed from crab eggshells.
Its removal performance was compared to that of natural clay. Both the composite and raw clay were used to remove target pollutant. The outcomes of the chitosan load in the composite, size particles, initial dye concentration, contact time, pH, and temperature on the dye's elimination were essayed in batch manners. The composite with 30% (w/w) of chitosan exhibited the highest dye removal. At pH 2, an adsorption capacity of 84 mg/g was accomplished, arguing that the grafting of the polymer onto clay surface raises its efficacity and stability in acidic environments. This finding was beared by characterization data obtained from X-ray diffraction (XRD), skiming electron microscopy (SEM), dispersive X-ray spectroscopy (EDX), and Fourier transform infrared (FT-IR) analyses.
