Change of perspective through quality assurance measures on microplastic particle counts in surface waters of the Rhine River - Importance of LOD and LOQ

open access: yes, 2023
Abstract The issues surrounding micro- and nanoplastics (MPs and NPs) are gaining importance as the knowledge about their distribution and impacts on the environment and human health grows. In order to gain a better understanding about the occurrence of those plastic particles and the pollution of different freshwater systems, the project ...

Detection of the GH Analogue Redalsomatropin Alfa in Sports Drug Testing: Immunological Approaches and LC‐HRMS/MS

open access: yesDrug Testing and Analysis, EarlyView.
After evaluating the compatibility of the GH analogue redalsomatropin alfa with approved doping control immunoassays for rhGH, it was implemented into the existing detection method for somatrogon employing affinity purification with GHR‐Fc‐conjugated magnetic beads, tryptic digestion, and LC‐HRMS/MS to allow for a specific and sensitive detection ...

Determination of THC and THC‐COOH in Dried Capillary Blood Spots and Comparison to Venous Blood of Recreational Cannabis Consumers in a Pilot Study

open access: yesDrug Testing and Analysis, EarlyView.
A new extraction method was developed and validated for the extraction of THC and THC‐COOH from capillary blood samples collected as dried blood spots. The extracts were analysed using HPLC–MS/MS resulting in high extraction efficiencies for both THC and THC‐COOH.

Elimination Profile of Deflazacort and Metabolites in Urine and Plasma Following Oral Administration: Relevance to Sports Drug Testing

open access: yesDrug Testing and Analysis, EarlyView.
Results confirm that the MRL of 30 ng/mL for 21‐desacetyl‐deflazacort together with a 3‐day washout period is an appropriated strategy to detect oral deflazacort administration in sport competition. ABSTRACT Deflazacort (DEF) is a glucocorticoid prohibited in sports competitions when orally administered.
