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

Drug Testing and Analysis, Volume 17, Issue 6, Page 903-914, June 2025.
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.

Utilizing Caenorhabditis Elegans as a Rapid and Precise Model for Assessing Amphetamine‐Type Stimulants: A Novel Approach to Evaluating New Psychoactive Substances Activity and Mechanisms

Advanced Science, Volume 12, Issue 17, May 8, 2025.
This study uses Caenorhabditis elegans to assess the activity of amphetamine‐type stimulants (ATS) and their analogs. The research highlights the roles of dopamine and serotonin pathways, distinguishes chiral forms of ATS, and identifies structure‐activity relationships. These findings provide a rapid and cost‐effective model for evaluating the effects

Detoxification of 3,4-dichloroaniline in soybean by n-malonylation [PDF]

, 2003
3,4-Dichloroaniline (DCA), the degradation product of certain herbicides, is not readily degraded by micro-organisms and, due to its persistence in the environment, is considered to be a reference xenobiotic.
