Summary: Carboxymethyl bacterial cellulose (CMCn) was synthesized from bacterial cellulose from nata de coco by carboxymethylation using different NaOH concentrations, with the optimal condition resulting from 30g/100mL NaOH providing the highest DS value. The tensile strength of CMCn films increased with NaOH concentration up to 30g/100mL, but decreased at higher concentrations. The highest elongation at break was obtained from CMCn films synthesized with 50g/100mL NaOH concentration.

Summary: In this study, quaternized and crosslinked carboxymethylcellulose sodium (QCCMC) films, as well as quaternized (QCMC) and crosslinked CMC Na (CCMC) derivatives, were prepared using a one-step synthesis. The derivatives were characterized using high-resolution nuclear magnetic resonance (NMR) spectroscopy. Size-exclusion chromatographic multi-angle laser light scattering (SEC-MALS) was used to determine the solubilities of the derivatives and the gyration radii (Rg) of the polysaccharide coils.

Summary: In this study, antimicrobial nanocomposite films were fabricated using biocompatible polymers sodium carboxymethyl cellulose (CMC) and sodium alginate (SA) reinforced with nanosilver (Ag) and graphene oxide (GO) using the solvent casting approach. The addition of GO increased the thermal and mechanical performance of the CMC/SA/Ag-GO nanocomposites. The CMC/SA/Ag-GO2% nanocomposite exhibited the highest zone of inhibition against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Furthermore, the CMC/SA/Ag-GO nanocomposites showed excellent antibacterial activity due to the synergistic effects of GO and Ag, and their cytotoxic activity was also assessed for biocompatibility evaluation.

Summary: In this study, bacterial cellulose from nata de coco was modified into carboxymethyl cellulose (CMC) form using various concentrations of monochloroacetic acid (MCA), with the optimum treatment found to be 24 g of MCA per 15 g of cellulose. Different concentrations of MCA affected the degree of substitution (DS), chemical structure, viscosity, color, crystallinity, and morphology of CMCn. The use of various MCA concentrations also increased the mechanical properties and water vapor permeability of CMCn, which were related to the DS value.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
