High-Coverage Disulfide Mapping Enabled by Programmable Disulfide-Ene Reaction Integrated onto a Bottom-Up Protein Analysis Workflow.

Mapping disulfide linkages is crucial for characterizing pharmaceutical proteins during drug development and quality control. Traditional bottom-up protein analysis workflows often suffer from incomplete mapping for tryptic peptides consisting of multiple disulfide bonds. Although the employment of a partial reduction of disulfide bonds can improve disulfide mapping, it becomes a bottleneck of analysis because individual tuning is often needed.

Factors affecting voriconazole concentration to dose ratio changes according to route of administration.

Background: Voriconazole (VRCZ) is commonly used as oral and intravenous (IV) formulations. Few studies have comprehensively analysed the variation factors for the weight-corrected VRCZ serum concentration/dose (C/D) ratio based on the administration route. We retrospectively investigated the risk factors that influence the VRCZ C/D ratio in patients treated with oral or IV formulations.

Influence of cerebrospinal fluid drainage and other variables on the plasma vancomycin trough levels in postoperative neurosurgical patients.

Background: Therapeutic drug monitoring (TDM) aims to minimise the clinical impact of vancomycin (VCM) pharmacokinetic variability. However, TDM data are limited among specific patient populations, including postoperative neurosurgical populations. The objective of this study was to retrospectively investigate the influence of cerebrospinal fluid (CSF) drainage and other factors on the serum trough concentrations of VCM.
