UHPLC‐QTOFMS Urine Drug Screening With Dilute‐and‐Shoot Sample Preparation and Vacuum‐Insulated Probe‐Heated Electrospray Ionization

Drug Testing and Analysis, EarlyView.
The new ionization technique, vacuum‐insulated probe‐heated electrospray, allows for a simple dilute‐and‐shoot sample preparation to be used with liquid chromatography time‐of‐flight mass spectrometry in urine drug screening. Comparison with a method relying on solid‐phase extraction and conventional electrospray ionization shows improved performance ...

Cost Minimized Immunoaffinity Purification of EPO and Its Analogs in Doping Control—A Step‐by‐Step Protocol for Human Urine and Blood

Drug Testing and Analysis, EarlyView.
A cost minimized immunoaffinity protocol was developed, which allows the direct purification of ERAs from human urine. After slight modification, the protocol is also applicable to serum and plasma and is fully compliant with WADA TD2024EPO. Compared to commercial EPO‐purification kits, the material costs are significantly lower.

The Impact of Triptorelin on Hormone Levels in Human and Its Metabolite Confirmation Using Liquid Chromatography–Ion Trap/Time‐of‐Flight Mass Spectrometry (LC/MS‐IT‐TOF) and Liquid Chromatography–Orbitrap (LC‐Orbitrap) for Doping Control Analysis

Drug Testing and Analysis, EarlyView.
Triptorelin (5–10) confirmation using LC/MS‐IT‐TOF and LC‐Orbitrap can be used as evidence of triptorelin abuse in doping control. ABSTRACT Triptorelin, a synthetic gonadotrophin‐releasing hormone (GnRH), is mainly used in the clinical treatment of prostate cancer.

Identification and Investigation of the Intrinsic Receptor Activation Potential and Metabolization of the New Oxo‐Pyridyl Synthetic Cannabinoid Receptor Agonist CH‐FUBBMPDORA

Drug Testing and Analysis, EarlyView.
Another Chinese generic ban‐evading SCRA, CH‐FUBBMPDORA, has emerged. This study reports its first identification in Europe, its analytical characterization (NMR, Raman, FTIR, GC–MS, and HRMS), its cannabinoid activation potential in a βarr2 recruitment assay, and its metabolization profile.

Arrhythmia onsets triggered by acute myocardial ischemia are not mediated by lysophosphoglycerides accumulation in ventricular myocardium

Scientific Reports
Lysophosphoglycerides (LPLs) have been reported to accumulate in myocardium and serve as a cause of arrhythmias in acute myocardial ischemia. However, in this study we found that LPLs level in the ventricular myocardium was decreased by the onset of ...
