Efficacy of Intracameral Mydriatics in Pediatric Lens Surgery.

Introduction: The aim of this study was to evaluate the efficacy of intracameral administration of Mydrane® in children undergoing lens surgery.

Methods: We set up a single center prospective cohort trial including 40 consecutive patients between 8 weeks and 17 years old who were planned for lens surgery, including cataract, persistent fetal vasculature or lens subluxation. We injected 0.

A key factor in monitoring cannabis consumption trends through wastewater analysis: Partitioning of THCCOOH between the liquid and solid phase of influent wastewater.

Current wastewater-based epidemiology (WBE) studies are predominantly focused on the analysis of urinary biomarkers present in the liquid phase of influent wastewater (IWW). This approach systematically underestimates less polar metabolites, such as cannabis biomarkers. These biomarkers can potentially sorb to and desorb from suspended particulate matter (SPM) present in IWW.

Trapped and drift-tube ion-mobility spectrometry for the analysis of environmental contaminants: Comparability of collision cross-section values and resolving power.

Rationale: Ion-mobility (IM)-derived collision cross-section (CCS) values can serve as a valuable additional identification parameter within suspect and non-target screening studies of environmental contaminants. However, these applications require to assess the reproducibility of CCS calculations between different IM set-ups. Especially for the comparison of trapped and drift-tube IM (TIMS/DTIM) derived CCS values, data for environmental applications is lacking.

Electrochemical classification of benzodiazepines: A comprehensive approach combining insights from voltammetry and liquid chromatography - mass spectrometry.

The growing non-medical use of benzodiazepines (BZs) has led to the emergence of counterfeit BZ pills and new psycho-active substances (NPS) in the BZ class on the illicit market. Comprehensive analytical methods for BZ identification are required to allow law enforcement, first aid responders and drug-checking services to analyze a variety of sample types and contents to make timely decisions on the spot. In this work, the electrochemical behavior of diazepam (DZ), clonazepam (CZ) and alprazolam (AP) is studied on graphite screen-printed electrodes, both with and without dissolved oxygen in the solution, to link their redox signals to their chemical structure.
