Analysis of doping control samples using supercritical fluid chromatography‐tandem mass spectrometry: Ready for routine use

Journal of Separation Science, Volume 46, Issue 7, April 2023., 2023
Supercritical fluid chromatography is proving to be a good separation and sample preparation tool for various analytical applications and, as such, has gained the attention of the anti‐doping community. Here, the applicability of supercritical fluid chromatography hyphenated to tandem mass spectrometry for routine doping control analysis was tested.

Setting up criteria for drug‐induced autoimmune‐like hepatitis through a systematic analysis of published reports

Hepatology Communications, Volume 6, Issue 8, Page 1895-1909, August 2022., 2022
Although some drugs have well‐documented ability to induce autoimmune‐like disorder, documented evidence for many other drugs and herbal and dietary supplements (HDS) has not been analyzed. Criteria for drug‐induced hepatitis (DI‐AIH) were set up to analyze case reports of suspected Di‐AILH.
