BACKGROUND: Acinetobacter baumannii is a health threat due to its antibiotic resistance antibiotic susceptibility and its association with the Toxin-antitoxin (TA) system cistrons in A. baumannii clinical isolates from Iran were enquired we readyed meropenem-adulterated chitosan nanoparticles (MP-CS) and inquired their antibacterial upshots against meropenem-susceptible bacterial isolates Out of 240 clinical specimens, 60 A. baumannii isolates were measured. Antibiotic resistance of the isolates against conventional antibiotics was determined alongside investigating the presence of three TA system cistrons (mazEF, relBE, and higBA). Chitosan nanoparticles were characterised in terminusses of size, zeta potential, encapsulation efficiency, and meropenem release activity. Their antibacterial effects were valuated utilising the well diffusion method, minimum inhibitory concentration (MIC), and colony-organising unit (CFU) counting. Their cytotoxic cores and biocompatibility index were defined via the MTT, LDH, and ROS formation attempts Ampicillin, ceftazidime, and colistin were the least effective, and amikacin and tobramycin were the most effective antibiotics.
Out of the 60 isolates, 10 (16%), 5 (8%), and 45 (75%) were multidrug-resistant (MDR), extensively drug-resistant (XDR), and pandrug-resistant (PDR), respectively. TA system cistrons had no significant effect on antibiotic resistance. MP-CS nanoparticles demonstrated an average size of 191 and zeta potential of 27 mV alongside a maximum encapsulation efficiency of 88% and release rate of 69%. MP-CS nanoparticles liaised similar antibacterial gists, as likened with free meropenem, against the A. baumannii sequesters with significantly lower layers of meropenem. MP-CS nanoparticles remarkably forestalled A549 and NCI-H292 cell infection by the A. baumannii isolates alongside attesting a favorable biocompatibility index Antibiotic-loaded nanoparticles should be further designed and enquired to increase their antibacterial effect against A.
baumannii and assess their safety and applicability in vivo scopes.Fabrication and characteristics of multifunctional hydrogel fertilizations habituating dopamine altered hyaluronic acid and phenylboronic acid changed chitosan.The healing of damaged skin is a complex and dynamic process, and the multi-functional hydrogel bandagings could promote skin tissue healing. This study, therefore, explored the development of a composite multifunctional hydrogel (HDCP) by integrating the dopamine changed hyaluronic acid (HA-DA) and phenylboronic acid modified chitosan (CS-PBA) crosslinked using boric acid ester hampers. The integration of HA-DA and CS-PBA could be supported habituating the Fourier transform infrared spectrometer and (1)H nuclear magnetic resonance psychoanalysisses. The fabricated HDCP hydrogels exposed porous structure, elastic solid behavior, shear-thinning, and adhesion properties the HDCP hydrogels showed antibacterial efficacy against Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S.
aureus) the cytocompatibility of the HDCP hydrogels was verified through CCK-8 assay and fluorescent image analysis adopting co-cultivation with NIH-3T3 cells. This research portraies an innovative multifunctional hydrogel that reserves promise as a wound dressing for various applications within the realm of wound healing.Impact of chitosan pulled from shrimp shells on the shrinkage and mechanical attributes of cement-based composites using dendritic fibrous nanosilica.Dendritic fibrous nanosilica (DFNS) was functionalized practicing microcrystalline chitosan, deduced from shrimp exoskeletons, to act as a robust anchor, leaving in DFNS@Chitosan.
