LC-HRMS of derivatized urinary estrogens and estrogen metabolites in postmenopausal women [PDF]

Journal of Chromatography B, 2020
In order to undertake an epidemiologic study relating levels of parent estrogens (estrone and estradiol) and estrogen metabolites (EMs) to other breast cancer risk factors, we have optimized methods for EM quantification with ultra high performance liquid chromatography-high resolution mass spectrometry (UHPLC-HRMS).

Metabolism Profile of Mequindox in Sea Cucumbers In Vivo Using LC-HRMS

Antibiotics, 2022
In this work, the metabolism behavior of mequindox (MEQ) in sea cucumber in vivo was investigated using LC-HRMS. In total, nine metabolites were detected and identified as well as the precursor in sea cucumber tissues. The metabolic pathways of MEQ in sea cucumber mainly include hydrogenation reduction, deoxidation, carboxylation, deacetylation, and ...
