Fabrication , characterization , and optimisation of a novel copper-incorporated chitosan/gelatin-based scaffold for bone tissue technology applications.Introduction : Fabricating composite scaffolds with improved physicochemical props as artificial microenvironments are of great interest in bone tissue engineering . presumption advantageous holdings of nano-hydroxyapatite/chitosan/gelatin ( nHA/Cs/Gel ) scaffolds , the present study aspired to synthesise a modified nHA/Cs/Gel biomimetic scaffold with improved characteristics Pure and copper ( Cu ) -substituted nHA was synthesised using the chemical precipitation method under controlled pH and temperature . Pure and Cu-substituted nHA/Cs/Gel scaffolds were fabricated by salt-leaching/freeze-drying method . Physicochemical features of nanoparticles and scaffolds were explored using XRD , FTIR , FE-SEM/EDX , and ICP . Besides , scaffold mechanical enduringness , abasement , porousness , swelling , biomineralization , and cytocompatibility were taxed Pure and Cu-substituted nHA were synthesised and characterised with appropriate Cu switch and improved physical properties .
All scaffolds were extremely holey ( porousness > 98 % ) and Cu incorporation repressed porosity from 99 ± 0 % to 98 ± 0 % while expounded the pore size to more than100 µm . Cu-substitution improved the scaffold mechanical strength and the best upshot was observed in nHA.Cu5 % /Cs/Gel scaffolds by the compressive metier 88 ± 19 MPa . Furthermore , 3 % and 5 % Cu-substituted nHA enhanced the scaffold structural constancy and supported osteoblast outspread , adhesion , endurance , mineralization , and proliferation semipermanent and sustainable Cu release from scaffolds was observed within 28 days Cu-substituted nHA/Cs/Gel scaffolds mimic the porous structure and mechanical forte of cancellous bone , along with lengthy degradation and Cu release , osteoblast bond , viability , calcium deposition , and proliferation . engage together , our upshots show the upgraded dimensions of nHA.Cu5 % /Cs/Gel scaffolds for succeeding coverings in bone tissue engineering.3-Formylindole-based chitosan Schiff base polymer : Antioxidant and in vitro cytotoxicity sketchs on THP-1 cells .
Two imine differentials of chitosan ( i-CTs ) , videlicet 2FCT and 5MCT , were synthesized by responding chitosan ( CT ) with 2- ( 3-formyl-1H-indol-1yl ) acetonitrile ( 2F ) , and 5-methoxyindole-3-carbaldehyde ( 5M ) , respectively . The antimicrobial rating of i-CTs exhibited stronger inhibition effect against Staphylococcus aureus , Escherichia coli and Candida albicans . The antioxidant activity of 2FCT and 5MCT evidenced strong scavenging power with IC ( 50 ) 2 and 6 μg/mL , severally . The results of in vitro cytotoxicity of 2FCT and 5MCT examined using human monocyte leukaemia ( THP-1 ) cellphones indicate no cytotoxic event on host cells and the value of cell viability was bumped to be 87 and 84 % , respectively . Measurement of intracellular Reactive O Species ( ROS ) yield by flow cytometry analysis revealed that the 2FCT and 5MCT reduced the ROS generation by 83 and 43 % , respectively . In summary , these determinations show that i-CTs synthesized to be promising biomaterial for biomedical coatings such as wound healing.Effect of chitosan-based gel dressing on injury infection , synechia , and granulations after endoscopic sinus operation of nasal polyps : A meta-analysis .
A meta-analysis was performed to appraise the effect of chitosan-based gel cliping on wound infection , synechia , and granulations after endoscopic sinus operation of nasal polyps . A taxonomic lit search until March 2022 incorporated 386 subjects after endoscopic sinus surgery of adenoidal polypus at the get-go of the discipline ; 187 were utilizing chitosan-based gel dressing , and 199 were dominance . Statistical peters like the dichotomous method were used within a random or fixed-influence model to base the odds ratio ( OR ) with 95 % self-confidence intervals ( CIs ) to judge the influence of chitosan-based gel dressing on lesion infection , synechia , and granulations after endoscopic sinus surgery of adenoidal polyps .
