This review presents the evolution of steroid analytical techniques, including gas
chromatography coupled to mass spectrometry (GC–MS), immunoassay (IA) and targeted …

Accurate measurement of sulfated steroid metabolite concentrations can not only enable the
elucidation of the mechanisms regulating steroid metabolism, but also lead to the diagnosis …

The present study investigated the occurrence of 13 parent and conjugated estrogens and
progestagens in surface water of the Santa Ana River. With the exception of the synthetic …

Steroid detection and identification remain key issues in toxicology, drug testing, medical
diagnostics, food safety control, and doping control. In this study, we evaluate the …

The metabolic genes encoding isocitrate dehydrogenase (IDH1, 2) are frequently mutated in
gliomas. Mutation of IDH defines a distinct subtype of glioma and predicts therapeutic …

Steroid sulfatase (STS) deficiency is the underlying cause of the skin condition known as
recessive X-linked ichthyosis (RXLI). RXLI patients show scales on their skin caused by high …

Various separation and mass spectrometric (MS) techniques have furthered our ability to
study complex mixtures, and the desire to measure every analyte in a system is of continual …

Chemical communication is widespread in amphibians, but if compared to later diverging
tetrapods the available functional data is limited. The existing information on the …

A method for structural elucidation of biomolecules dating to the 1980s utilized high-energy
collisions (~ 10 keV, laboratory frame) that induced charge-remote fragmentations (CRF), a …

A mixture of α-cyano-4-hydroxycinnamic acid and 1, 5-diaminonaphthalene was discovered
as a novel binary matrix for the qualitative analysis of 14 small-molecule (∼ 250–550 Da) …
