Post‐Mortem Identification and Toxicological Findings of Fluetonitazepyne and Isotonitazepyne
Drug Testing and Analysis, EarlyView.In early 2025, five death cases in Finland tested positive for fluetonitazepyne and one for isotonitazepyne in urine drug screening. A peak corresponding to O‐dealkylated fluetonitazepyne, the 4‐OH‐nitazepyne metabolite, was present in all fluetonitazepyne‐positive urine samples and was later used in the identification of isotonitazepynein one fatal ...

Dopamine D4 receptor activation counteracts nigrostriatal pathway activation by morphine: relevance in drug addiction. [PDF]
, 2013 Morphine induces dopamine release in the caudate putamen (CPu), which promotes stereotyped behavior and habit learning for drug-seeking and –taking. Nigrostriatal pathway stimulation by morphine is due to a removal of tonic inhibition arising from SNr ...

Evaluation of Therapeutic Opioids in Hair of Neonatal and Pediatric Patients
Drug Testing and Analysis, EarlyView.This study investigated the incorporation of novel and traditional medically used opioids into the hair of 118 pediatric and neonatal patients. Concentrations (median [range]) in hair were as follows: fentanyl: 4.03 pg/mg [0.10–343], sufentanil: 0.31 pg/mg [0.10–8.64], remifentanil: 0.14 pg/mg [0.10–0.43], and morphine: 27.4 pg/mg [1.0–1870].

Characterization of a Single Chain Fv Antibody that Reacts with Free Morphine
Antibodies, 2013 An immune phage library derived from mice, hyperimmunized with morphine-conjugated BSA, was used to isolate a single-chain Fv (scFv) clone, M86, with binding activity to morphine-conjugated thyroglobulin (morphine-C-Tg) but not to codeine-, cocaine-, or ...
