Bile salt synthesis, secretion into the intestinal lumen, and resorption in the ileum occur in all
vertebrate classes. In mammals, bile salt composition is determined by host and microbial …

A method is described for multiple monolithic fiber solid-phase microextraction of five sterol
and steroid hormones from complex food samples. A composite was prepared from …

A 27-day controlled exposure study of adult male African clawed frogs (Xenopus laevis) was
conducted to examine the mechanism by which tebuconazole may disrupt steroidogenesis …

Monitoring complex endocrine pathways is often limited by indirect measurement or
measurement of a single hormone class per analysis. There is a burgeoning need to …

Abstract The US Environmental Protection Agency Endocrine Disruptor Screening Program
and the Organization for Economic Co-operation and Development (OECD) have used the …

Serum steroid assays are major tools in the clinical evaluation of adrenal disorders. The
main adrenal steroids are routinely measured with immunoassays. However …

Disruption of steroidogenesis by environmental chemicals can result in altered hormone
levels causing adverse reproductive and developmental effects. A high-throughput assay …

Measuring both progestagens, androgens, corticosteroids as well as estrogens with a single
method makes it possible to investigate the effects of endocrine-disrupting chemicals …

Endocrine disrupting chemicals have been reported to exert effects directly on enzymes
involved in steroid biosynthesis. Here, we present a new liquid chromatography-tandem …

The screening of endocrine disrupting chemicals (EDCs) that may alter steroidogenesis
represents a highly important field mainly due to the numerous pathologies, such as cancer …
