Summary: This study designed a smart formulation of (S)-ketamine for buccal administration to improve absorption by increasing contact with mucosa components. Rheological and mucoadhesion tests were conducted to determine the optimal concentrations and components of the formulation. The study also found that batch-to-batch variability did not have a significant impact on drug release profile. This optimized formulation has fast release and potential clinical value, especially in emergencies.

Summary: The type and concentration of charged groups in polymers play a crucial role in mucoadhesive interactions. This study investigated the correlation between chemical structure and mucin-polymer interactions by designing cationic poly(amino acid)s with different charge densities. The results showed that the interactions between mucin and polyaspartamides with at least 50% cationic groups displayed a non-linear change, causing increased light scattering. The analysis further revealed that fully cationic polyaspartamide is not necessarily superior, and the maximum adsorbed mass of polymers on mucin occurred at medium cationic group contents. This highlights the importance of cationic polyaspartamides as mucoadhesive excipients due to their multiple functionalities.

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.
