Polyelectrolyte complexes (PEC) of chitosan and ulvan were fabricated to study alkaline phosphatase ( ALP) mediated formation of apatitic minerals. Scaffolds of the PEC were subjected to ALP and successful mineral formation was studied using SEM, Raman and XRD techniques. Investigation of the morphology via SEM shows globular structures of the deposited minerals, which promoted cell attachment, proliferation and extracellular matrix formation. The PEC and their successful calcium phosphate based mineralization offers a greener route of scaffold fabrication towards developing resorbable materials for tissue engineering.

Summary: Cardiovascular diseases are the leading cause of death worldwide. Poly(alkylene terephthalate)s (PATs) with longer alkyl chain lengths show potential for improving compliance in vascular graft materials. This study investigated the effects of polymer molar mass and alkyl chain length on the surface properties of spin-coated PAT films, as well as endothelial cell adhesion and proliferation. The results showed that higher molar mass and longer alkyl chain lengths increased surface roughness, while no significant trend was observed for wettability. All investigated PATs were non-cytotoxic and supported endothelial cell adhesion and growth, with some PATs even promoting angiogenic maturation.

High-throughput intact Glycopeptide quantification strategy with targeted-MS (HTiGQs-target) reveals site-specific IgG N-glycopeptides as biomarkers for hepatic disorder diagnosis and staging

Xuejiao Liu, Bin Fu, Jierong Chen, Zhenyu Sun, Dongdong Zheng, Zhonghua Li, Bing Gu, Ying Zhang, Haojie Lu

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.
