Dried blood spot analysis in antidoping: Technical challenges, analytical advances, and future perspectives

open access: yesBulletin of the Korean Chemical Society, Volume 47, Issue 6, Page 674-688, June 2026.
Dried blood spot (DBS) analysis enables minimally invasive blood collection with strong analyte stability and simplified logistics, supporting anti‐doping applications beyond traditional matrices. Recent advances address hematocrit, volume variability, and matrix effects while expanding coverage to steroid esters, World Anti‐Doping Agency‐listed ...

A Personalised and Gamified Digital Decision Aid for Colorectal Cancer Screening: A Randomised Controlled Pilot Study

open access: yesCancer Medicine, Volume 15, Issue 6, June 2026.
ABSTRACT Background Colorectal cancer (CRC) is the second leading cause of tumour‐related mortality worldwide, accounting for approximately 903,000 deaths annually. Despite the proven effectiveness of population‐based screening in reducing mortality, participation rates remain suboptimal, hindered by cognitive, psychological, and socioeconomic barriers.

Effect of Reaction Time and Temperature on the Impurity Profile of Amphetamine in the Leuckart Method

open access: yesDrug Testing and Analysis, Volume 18, Issue 6, Page 725-738, June 2026.
This study investigates the effect of the reaction temperature (step 1) and reaction time (step 1 and 2) on the conversion efficiency and impurity profile of amphetamine synthesized via the Leuckart method. Conversion efficiency and impurity profile were assessed using gas chromatography–flame ionization detection (GC–FID) and GC–mass spectrometry (GC ...

In Vivo and In Vitro Evaluation of PTeCA (1H‐Pyrrole‐2,3,4,5‐Tetracarboxylic Acid) in Hair Matrix as a Marker for Oxidative Cosmetic Treatment

open access: yesDrug Testing and Analysis, Volume 18, Issue 6, Page 739-749, June 2026.
A total of 3378 self‐reported treated and untreated hair samples were analyzed for PTCA and PTeCA by LC‐MS/MS. Moreover, their in vitro formation was assessed in 225 untreated hair by different cosmetic treatments with and without oxidative agents. Data suggest that PTeCA could be a reliable marker for oxidative cosmetic treatments in hair.

Chemical Straightening as a Source of Analytical Variability in Hair Testing: A Dual‐Analyte Case Report

open access: yesDrug Testing and Analysis, Volume 18, Issue 6, Page 771-776, June 2026.
Permanent chemical hair straightening was associated with analyte‐dependent changes in hair concentrations, showing increased endogenous GHB levels and decreased alprazolam concentrations after treatment. These results suggest that chemical hair straightening procedures may influence hair concentrations and should be considered when interpreting hair ...
