Steroid hormones (SH) play a number of important physiological roles in vertebrates
including fish. Changes in SH concentration significantly affect reproduction, differentiation …

Sex steroid hormones are potential biomarkers of reproductive function in teleost fish, but
their measurement continues to rely on antibody-based assays. The objective of this study …

Quantification of steroid hormones in fish is an important step for toxicology and
endocrinology studies. Among the hormone analysis techniques, liquid chromatography …

A new, sensitive, and rapid method based on the Quick, Easy, Cheap, Effective, Rugged and
Safe (QuEChERS) approach and air-assisted liquid-liquid microextraction (AALLME) …

A hybrid solid phase extraction (HybridSPE) protocol tailored to ultra-performance
convergence chromatography tandem mass spectrometry (UPC 2-MS/MS) was developed …

This study aims to provide a rapid, sensitive and precise UPLC–MS/MS method for target
steroid quantitation in biological matrices. We developed and validated an UPLC–MS/MS …

The quantification of steroid hormones of individual zebrafish (Danio rerio) provides
perspective to understand endogenous hormone function. A UPLC–TOF–MS method was …

Capillary electrophoresis and UV-visible absorbance detection are used with sample
stacking to achieve detection limits ranging from 0.2 to 2 ng/mL (0.8 to 6 nM) for steroids …

Steroid hormones are a diverse group of natural and synthetic compounds. Their wide use
in human and veterinary medicine results in their continual introduction into the …
