[PMID: 38906342 DOI: 10.1016/j.ijbiomac.2024.133278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 06/11/2024] [Accepted: 06/18/2024] [Indexed: 06/23/2024]
Abstract
Removing free hemoglobin generated during extracorporeal circulation remains a challenge. Currently, there is no adsorbent with specificity and good biosafety for removing hemoglobin. In this study, a new chitosan/sodium alginate/carbon nitride (CS/SA/C3N4) hydrogel adsorbent was prepared by blending SA with C3N4 to drop into CS/CaCl2 solution. The physicochemical properties of CS/SA/C3N4 hydrogel were evaluated using some techniques, including scanning electron microscope, Zeta potential measurement, and thermogravimetric analysis. Hemoglobin adsorption in vitro, stability, hemocompatibility, cell compatibility, inflammatory reaction and blood extracorporeal circulation in vivo were also evaluated. The findings revealed that the CS/SA/C3N4-0.4 % hydrogel exhibited an impressive adsorption capacity of 142.35 mg/g for hemoglobin. The kinetic data of hemoglobin adsorption were well-described by pseudo second-order model, while the isothermal model data conformed to the Langmuir model. The hardness and modulus of CS/SA/C3N4-0.4 % was 11.7 KPa and 94.66 KPa respectively, which indicated robust resistance to breakage. CS/SA/C3N4 demonstrated excellent hemocompatibility, biocompatibility and anti-inflammatory properties. In addition, the results of in vivo rabbit extracorporeal blood circulation experiment demonstrated that CS/SA/C3N4 could adsorb free hemoglobin from blood while maintaining high biosafety standard. Consequently, CS/SA/C3N4 hydrogel emerges as a promising candidate for use as a hemoglobin adsorbent in extracorporeal blood circulation system.

Abstract
Three-dimensional (3D) bioprinting is a fast prototyping fabrication approach that allows the development of new implants for tissue restoration. Although various materials have been utilized for this process, they lack mechanical, electrical, chemical, and biological properties. To overcome those limitations, graphene-based materials demonstrate unique mechanical and electrical properties, morphology, and impermeability, making them excellent candidates for 3D bioprinting. This review summarizes the latest developments in graphene-based materials in 3D printing and their application in tissue engineering and regenerative medicine. Over the years, different 3D printing approaches have utilized graphene-based materials, such as graphene, graphene oxide (GO), reduced GO (rGO), and functional GO (fGO). This process involves controlling multiple factors, such as graphene dispersion, viscosity, and post-curing, which impact the properties of the 3D-printed graphene-based constructs. To this end, those materials combined with 3D printing approaches have demonstrated prominent regeneration potential for bone, neural, cardiac, and skin tissues. Overall, graphene in 3D bioprinting may pave the way for new regenerative strategies with translational implications in orthopedics, neurology, and cardiovascular areas.

A graphene-oxide-based fluorometric assay for norA gene transcription in MRSA using Nb.BbvCI-assisted target recycling and T7 exonuclease-triggered cascade dual recycling signal amplification. Talanta 2023; 259:124549. [PMID: 37062089 DOI: 10.1016/j.talanta.2023.124549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 03/05/2023] [Accepted: 04/10/2023] [Indexed: 04/18/2023]
Abstract
We describe a graphene oxide (GO)-based bioassay for the fluorometric determination of norA gene transcription (mRNA) in methicillin-resistant Staphylococcus aureus (MRSA). This approach is based on Nb.BbvCI-assisted target recycling (NATR) and T7 exonuclease (T7 Exo)-triggered cascade dual-recycling signal amplification (TTCDRSA). The system included GO, a capture probe (CP), an assistant probe (AP), two carboxyfluorescein (FAM)-labeled hairpins (HP1 and HP2), endonuclease Nb.BbvcI, and exonuclease T7. In the presence of a target, AP, together with the target RNA, can hybridise with CP via partial complementarity to one another and open its hairpin structure to form a triple complex that is recognised by Nb.BbvCI. Once the CP is cleaved, the released AP and target RNA can walk on the carboxylated graphene oxide (CGO) surface to bind with another CP which induces the next round of cleavage, accumulating many trigger probes (TPs). The TPs then activate TTCDRSA with the assistance of T7 Exo, HP1, and HP2 to produce large amounts of free FAMs. These free FAMs are repelled by GO and exhibit enhanced fluorescence signals at excitation/emission wavelengths of 480/514 nm. The limit of detection (LOD) of the bioassay was calculated to be 0.37 fM, and the linear range of the method ranged from 1 fM to 1 nM. More importantly, the bioassay also exhibited high sensitivity and selectivity for target RNA detection in real samples, which may open a new promising avenue for monitoring drug efflux and studying the mechanisms of drug actions.

Microwave-assisted extraction of pectin from grape pomace. Sci Rep 2022; 12:12722. [PMID: 35882905 PMCID: PMC9325980 DOI: 10.1038/s41598-022-16858-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Accepted: 07/18/2022] [Indexed: 11/10/2022] Open
Abstract
The utilization of microwave technique for the pectin extraction from grape pomace (Fetească Neagră and Rară Neagră), its influence on yield, galacturonic acid content, degree of esterification and molecular weight of pectin were analyzed. The optimal conditions of the extraction process were microwave power of 560 W, pH of 1.8 for 120 s. The pectin samples extracted by MAE in optimal conditions were analyzed by comparing with commercial apple and citrus pectin based on FT-IR analysis, thermal behavior, rheological characteristics and microstructure. The FT-IR analysis established the presence of different functional groups which are attributed to the finger print region of extracted pectin, while the rheological behavior presented a good viscoelasticity of pectin solutions. The obtained data assumes that grape pomace has a great potential to be a valuable source of pectin which can be extracted by simple and quick techniques, while maintaining analogous quality to conventional sources of pectin.
