Summary: Chitin hexanoate-graft-poly(epsilon-caprolactone) (ChHex-g-PCL) was found to be thermoplastic, and the thermoplasticity was confirmed by the formation of a melt-pressed film. Chitin hexanoates were prepared by hexanoylation of chitin and then the surface-initiated ring-opening graft polymerization of epsilon-caprolactone was conducted to graft PCL chains onto the hydroxy groups of chitin hexanoates. The molar substitution and degree of polymerization of the PCL graft chains were influenced by the catalyst, reaction time, and degree of substitution.

Summary: This study investigates the release of levetiracetam using poly(lactic acid), poly(epsilon-caprolactone), and their blend electrospun nanofibers as novel systems. Scanning electron microscopy confirms the smooth and beads-free morphology of the samples. With increasing levetiracetam content, the average diameters of the nanofibers also increase. FTIR spectroscopy is used for structural confirmation and observation of functional groups. X-ray diffraction reveals a decrease in crystallinity and different drug release kinetics are evaluated using various models.

Summary: The scaffolds of PCL/PHBV blends fabricated from fused deposition modeling showed no cytotoxicity, with the surface-treated scaffold with a 25/75 PCL/PHBV blend ratio exhibiting the highest proliferation of porcine chondrocytes and total GAGs. The scaffolds with LP and 1 M NaOH surface treatment had the highest proliferation of cells and GAGs after culture. Degradation behaviors, as well as compressive strengths, were also studied, with results suggesting that scaffolds with LP and surface treatment had the highest potential for cartilage scaffold applications.

Summary: Using polysaccharide nanocrystals as fillers in biodegradable polyesters can create completely biodegradable nanocomposites. The study found that chitin nanocrystals and cellulose nanocrystals have completely different effects on the crystallization of poly(epsilon-capro-lactone) (PCL). Chitin nanocrystals retard the nucleation and overall crystallization process of PCL, while cellulose nanocrystals promote nucleation and accelerate crystal growth.

Summary: Research has shown that preparing cellulose gelators (CLGs) by grafting poly(ethylene glycol)-based amphiphile (PGLE) onto cellulose nanofibers (CNFs) can stabilize oil-in-water emulsions with high oil volume. The stability and oil droplet sizes of CLGs depend on the degree of PGLE substitution, CLG concentration, and volume of aqueous phase.

Summary: The dynamic adsorption and desorption behaviors of rosin colloids onto and from CNFs and TOCNFs in aqueous media were investigated using QCM-D measurements. The effects of maleic anhydride modification, anionic surfactant, and Alum addition on the adsorption were studied. The results showed that maleic anhydride modification contributed to particle size reduction, an increase in Tg, and enhanced stability, while using an anionic surfactant increased the particle size and ionicity. The adsorption of rosin colloids was affected by the surface charge of CNFs and the presence of Alum.

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.
