Drug Testing and Analysis, EarlyView.A two‐stage transcriptomic filter comparing rHuEPO, exercise and altitude responses reduced 153 candidate genes to 50 that were unaffected by physiological stimuli. These retained transcripts offer focused biomarker leads to strengthen antidoping detection of rHuEPO.

Ethyl Glucuronide in Hair: A 10‐Year Overview
Drug Testing and Analysis, EarlyView.The present study builds on a unique collection of more than 68,000 hair EtG results collected in the Northen Italy between 2013 and 2022. We investigated trends in alcohol consumption in terms of age, gender, recidivism, applicants, sampling region, sampling length, across seasons, and the COVID‐19.

Drug Testing and Analysis, EarlyView.Tablets submitted to drug checking services that were found to contain bromazolam. Over half of these counterfeit tablets mimicked the appearance of licensed formulations (e.g., alprazolam Xanax bars and diazepam Roche 10 mg pills). Bromazolam is now the most commonly detected street benzodiazepine in drug poisoning deaths in the United Kingdom ...

Drug Testing and Analysis, EarlyView.This study examines the isomeric composition of PEth reference materials and compares it with the natural variation in isomer distribution found in blood samples. ABSTRACT The direct blood‐alcohol biomarker phosphatidylethanol (PEth), especially its most abundant analogue 1‐palmitoyl‐2‐oleoyl‐sn‐phosphatidylethanol (PEth 16:0/18:1) has gained ...

Drug Testing and Analysis, EarlyView.The paper describes an investigation related to the pentedrone norephedrine metabolite. The athlete's sample was analyzed using ultra‐performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS). According to the literature, this metabolite may originate from pentedrone, α‐pyrrolidinopentiophenone (PVP), or N‐ethylpentedrone (NEP).

Drug Testing and Analysis, EarlyView.A basic EPO IEF profile was identified in patients with familial erythropoiesis linked to mutations in noncoding parts of EPO gene. Comparison of blood and urine EPO profiles from these patients differed from adult wild‐type EPO (WT) and from Eprex‐administered patients. Patients' EPO do not differ from WT EPO after analysis using SDS‐PAGE/SAR‐PAGE. It

Neural Network‐Based Detection of Adulterants in Opioid Samples Using IR Absorption Spectroscopy
Drug Testing and Analysis, EarlyView.We construct a neural network for the classification of bromazolam and fluorofentanyl in illicit opioid samples. The model outperforms a random forest classifier and shows elevated performance for low concentration samples. ABSTRACT Community‐based drug checking services are challenged in their ability to reliably detect low concentration adulterants ...

Concentration and Detection Time of Nitrous Oxide in Blood Following Controlled Inhalation
Drug Testing and Analysis, EarlyView.In a study with controlled inhalation of nitrous oxide (N2O), elimination followed a two‐compartment model with half‐lives of 2.4 and 31 min, and N2O remained detectable in blood samples for 1–3 h after inhalation. ABSTRACT Recreational use of nitrous oxide (laughing gas, N2O) is becoming increasingly common and abuse is often seen in relation to ...
