Improving the Determination of Carbon Isotope Ratios of Endogenous Steroids Found in Human Serum

Drug Testing and Analysis, EarlyView.
A method employing high‐performance liquid chromatographic sample cleanup to determine the carbon isotope ratios of steroids found in human serum was developed and fully validated. A reference population encompassing more than 120 male and female athlete samples was investigated in order to establish population‐based thresholds for Δ‐values.

Multianalyte Approach—Including Automated Preparation of Calibrators—for Validated Quantification of 82 Drugs in Whole Blood by Liquid Chromatography–Tandem Mass Spectrometry

Drug Testing and Analysis, EarlyView.
In forensic bioanalysis, often multianalyte approaches are used given their increased effectiveness but can be difficult to develop and maintain in the laboratory, for example, in terms of calibrator solution preparation. A fast, simple, and robust liquid chromatography–tandem mass spectrometry (LC–MS/MS) method for the quantification of 82 classic ...

Rapid Analytical Method for Quantification of Gamma‐Hydroxybutyrate (GHB) in Hair by UPLC‐MS/MS

Drug Testing and Analysis, EarlyView.
A rapid and simple UPLC‐MS/MS method for quantification of GHB in 10 mg of hair was developed. The method was satisfactorily validated, showing a linear range of 0.5–50 ng/mg, which allows us to quantify endogenous and exogenous GHB concentrations.

Skeletal Muscle Memory: An Update From the Antidoping Perspective

Drug Testing and Analysis, EarlyView.
ABSTRACT This narrative review explores the concept of muscle memory, focusing on the physiological and biochemical mechanisms underlying information retention in skeletal muscle tissue as it relates to antidoping. The discussion encompasses the role of satellite cells (SCs) in myonuclei recruitment, resulting in increased myonuclear density and ...

Lipid and Corticosteroid Biomarkers Under the Influence of Bisphosphonates

Drug Testing and Analysis, EarlyView.
The detection of bisphosphonates is important due to the potential integrity and welfare issues associated with use of these substances. Targeted detection of a nitrogenous and non‐nitrogenous bisphosphonate was detected for 8 h and 28 days post‐administration, respectively.

Waxy‐ or Putty‐Like Materials as a Novel Drug Preparation for Synthetic Cannabinoid Receptor Agonists: Detection in Prisons and In Vitro Cannabinoid Receptor Activity

Drug Testing and Analysis, EarlyView.
Waxy‐ or putty‐like materials has emerged as a novel drug preparation for synthetic cannabinoids and other drugs in UK prisons. An in vitro CB1 bioassay was used to evaluate the CB1 activating potential of MDMB‐INACA and extracts from eight seized samples. MDMB‐INACA had moderate efficacy but low potency at CB1.
