Summary: Testing showed that adding stronger layers (TOCNFs + PVA) and increasing adhesion (APTES) in TOCNF laminates can increase flexural strength and bending modulus, while reducing fracture energy and generating different fracture modes. Additionally, using a more ductile epoxy can increase work of failure, but also lead to a higher risk of delamination.

Summary: Hydrogels made from renewable biopolymers and low-cost row materials have gained attention in biomedical applications. In this study, the sol-gel transition of TEMPO-oxidized nano-sized cellulose fibrils (TOCNFs) in the presence of polyvalent cations (Mg2+ and Ca2+) was investigated using multiple techniques. The results showed that ion concentration induced anisotropic swelling and increased flexibility in the nanofibrils, and the flexibility was also affected by the concentration of TOCNFs and the pH value. UV Resonant Raman spectroscopy revealed the structural organization and hydrogen-bonding properties of water in TOCNF dispersions and gels.

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.
