First Occurrence of Fatal Intoxication Involving Methiodone (IC‐26) in Finland; a Medicolegal Autopsy Case Report

Drug Testing and Analysis, EarlyView.
ABSTRACT Methiodone (IC‐26) is a non‐fentanyl novel synthetic opioid which has recently been detected in drug seizures in Europe. There is still limited data about the drug in published toxicological case work, both in non‐fatal and fatal cases. We present a medicolegal autopsy case report on a fatal intoxication in an individual undergoing opioid ...

Estimating Illicit Stimulant Drug Consumption in Luxembourg Using Wastewater‐Based Epidemiology

Drug Testing and Analysis, EarlyView.
Wastewater‐based epidemiology provided nationwide estimates of illicit stimulant consumption in Luxembourg, revealing higher urban use, weekend increases in cocaine and MDMA, and cocaine as the dominant stimulant. The approach offers an objective complement to conventional drug surveillance for informing public health and policy.

A Single‐Aliquot Strategy for Simultaneous Carbon Isotope Confirmation of 6‐Oxo‐Androstenedione and Testosterone Misuse in Doping Control

Drug Testing and Analysis, EarlyView.
This method enables simultaneous carbon isotope confirmation of 6‐oxo‐androstenedione and testosterone markers from a single urine aliquot, using bench‐top extraction, two preparative HPLC steps with intermediate acetylation, and GC/C/IRMS analysis. It was fully validated according to WADA requirements, and real samples demonstrated its fitness for ...

A proteomic investigation of forebrain regeneration in the leopard gecko (Eublepharis macularius)

Developmental Dynamics, EarlyView.
Our investigation reveals ontogenetic, injury‐ and regeneration‐associated proteomic changes in the leopard gecko forebrain. Abstract Background The ability to replace lost or damaged neurons following an injury is termed reactive neurogenesis. Although reactive neurogenesis has been reported in several lizard species, the molecular mechanisms ...
