volunteers ingested 20 mg of either flmodafinil or fladrafinil. Urine and blood (DBS) samples were analyzed by means of LC-HRMS, where limits of detection between 0.2 and 4 ng/mL were accomplished. After

Sixty participants, in four groups, younger than 12, 15, 16. and 23 yr (U12, U15, U16, U23), were analyzed. A Footbonaut, equipped with a 3D motion capture system consisting of 16 cameras, was used to capture

fraction) and human liver microsomes (HLMs) were analyzed. In addition, selected metabolites of SLU-PP-915 were synthesized and their structures were analyzed by nuclear magnetic resonance (NMR) spectroscopy

contamination of urine by seminal fluid. To this end, 480 seminal fluids from nonathletes were analyzed to identify concentration ranges and metabolite profiles of therapeutic drugs that are also classified

administration studies with 1, 10, and 50 μg of S-23 were conducted, and collected urine samples were analyzed by LC–MS/MS following enzymatic hydrolysis and solid-phase extraction. The analytical method was

samples were prepared for analysis using enzymatic hydrolysis followed by solid-phase extraction and analyzed via LC-HRMS/MS. Including isomers, a total of 15 phase I metabolites were detected in the urine

exploratory study, urine samples collected post-administration of 1.5 and 2.0 g of hypoxen were analyzed by means of liquid chromatography-high resolution/high mass accuracy (tandem) mass spectrometry

by gas chromatography/tandem mass spectrometry. All 23 commercially available hemp products were analyzed, and assay characteristicssuch as selectivity, limit of detection, limit of identification, limit

via Internet-based providers and advertised as EPO -gene- and IGF1 -gene-containing materials were analyzed for the presence of potential gene doping agents using a newly developed analytical approach, allowing

on of organically bound cobalt is permitted. To date, doping control urine samples are commonly analyzed for total cobalt concentrations by means of inductively coupled plasma mass spectrometry (ICP‐MS)
