Determination of hormones in water samples using liquid chromatography coupled with tandem mass spectrometry
PublicationOver the past few years, many synthetic (ethinylestradiol) and natural (estradiol,estriol, estrone) compounds present in the environment have been affecting the hormonalbalance of humans and animals. Steroid hormones are very often used for medical purposesand have high estrogenic activity what makes them endocrine disrupters. Most hormonalcompounds are released into the water as a result of their incomplete removal in wastewatertreatment...

Comparison of High Performance Liquid Chromatography Methods with Different Detectors for Determination of Steroid Hormones in Aqueous Matrices
PublicationThis paper presents the development and comparison of procedures for the qualitative and quantitative determination of five estrogenic compounds (17-a-ethynylestradiol, estrone, estradiol, estriol, and progesterone) in drinking water and wastewater samples. Five extraction columns and two disks were tested for their efficiency. The C18 columns were superior on the basis of cost for solid phase extraction of drinking water or sewage....

Relationships between concentrations of selected organohalogen contaminants and thyroid hormones and vitamins A, E and D in Faroese pilot whales
PublicationPilot whales (Globicephala melas) from the Faroe Islands, North-East Atlantic, have high body concentrations of organohalogenated compounds (OHCs), such as polychlorinated biphenyls (PCBs), organochlorinated pesticides (OCPs) and brominated flame retardants (BFRs). The aim of the present study was to examine if and to what extent blood plasma and liver concentrations of several groups of these OHCs are related to concentrations...

An electrochemical biosensor for the determination of hormone Human Chorionic Gonadotropin (hCG) in human serum
PublicationThis work describes the modification of a gold electrode to create an electrochemical biosensor capable of detecting human chorionic gonadotropin (hCG). The biosensor was obtained by modifying the gold electrode with cysteamine and oligopeptide (PPLRINRHILTR). The modification steps of the gold electrode were confirmed by cyclic voltammetry (CV) and impedance electrochemical spectroscopy (EIS) measurements. The conducted EIS experiments...

Recent progress in the development of steroid sulfatase inhibitors – examples of the novel and most promising compounds from the last decade
PublicationThe purpose of this review article is to provide an overview of recent achievements in the synthesis of novel steroid sulfatase (STS) inhibitors. STS is a crucial enzyme in the biosynthesis of active hormones (including estrogens and androgens) and, therefore, represents an extremely attractive molecular target for the development of hormone-dependent cancer therapies. The inhibition of STS may effectively reduce the availability...

Determination of sex hormone concentration in wastewater samples.
Open Research DataConcentration levels of five selected steroid hormones in influent and effluent waters from wastewater treatment plant were determined using SPE(C18)-HPLC-ESI/MS/MS method. Sex hormones like: estradiol, estriol, estrone, 17-α-ethynyloestradiol, progesterone were present in all influent wastwater samples.

Analityka hormonów steroidowych w próbkach materiałów biologicznych pobranych od człowieka
PublicationPróbki materiału biologicznego pobranego od człowieka (krew, mocz, ślina, łożysko, płyn owodniowy) mogą być źródłem cennych informacji o stanie zdrowia pacjenta. Wyniki zawartości hormonów steroidowych mogą być wykorzystane do diagnostyki hormonalnej lub w kontroli dopingu u sportowców. W pracy omówiono informacje literaturowe o dwóch podejściach w zakresie analityki hormonów steroidowych: - wykorzystanie bezpośrednich...

Hormony płciowe w środowisku - zagrożenia jakie niosą ze sobą
PublicationSpośród dużej ilości i różnorodności związków chemicznych dostających się do środowiska coraz większą uwagę i szczególne zainteresowanie poświęca się związkom endokrynnym (ang. Endocrine Disrupting Coumpounds - EDCs). Wśród związków endokrynnych to estrogeny zarówno naturalne jak i syntetyczne zostały wskazane i opisane jako związki niosące ze sobą największy potencjał aktywności estrogennej. Jednym z głównych źródeł estrogenów...

Bisphenols (A, S, and F) affect the basic hormonal activity determined for pharmaceuticals – Study of Saccharomyces cerevisiae
PublicationPharmaceuticals and analogs of bisphenol A (BPA) are increasingly threatening environmental pollutants. In this study, mixtures of selected pharmaceuticals (diclofenac sodium salt, chloramphenicol, oxytetracycline hydrochloride, fluoxetine hydrochloride, estrone, ketoprofen, progesterone, gemfibrozil and androstenedione) were prepared with BPA and its two analogs (namely, bisphenols F and S) at such ratios to reflect environmentally...
