A Receptor-Independent Effect of Estrone Sulfate on the hERG Channel

open access: yesJournal of Pharmacological Sciences, 2009
We recently reported that physiological concentrations of 17β-estradiol partially down-regulate cardiac rapidly-activating delayed rectifier K+ currents (hERG currents) independently of estrogen-receptor signaling.

Treatment and removal strategies for estrogens from wastewater [PDF]

open access: yes, 2008
Natural and synthetic steroidal estrogens (estrone, 17β-estradiol and 17α-ethinylestradiol) are endocrine disrupters, that are discharged consistently from the sewage treatment works into surface waters, thereby causing endocrine disrupting effects to ...

Urinary estrogen metabolites and gastric cancer risk among postmenopausal women

open access: yesCancer Reports, 2022
Background The overall incidence of gastric cancer in women is half that in men for most global populations. Sex hormone pathways may be involved in carcinogenesis and estrogens have been postulated to protect women against gastric cancer.

Concentrations of nine endogenous steroid hormones in 70-year-old men and women

open access: yesEndocrine Connections, 2021
Objectives: Circulating concentrations of endogenous steroids have systemic implications on health in elderly. However, population-based age- and ethnic ity-specific data are scarce.

TiO2-assisted photocatalytic degradation of diclofenac, metoprolol, estrone and chloramphenicol as endocrine disruptors in water

open access: yesAdsorption, 2013
The photocatalytic oxidation of diclofenac, metoprolol, estrone and chloramphenicol was tested in the tube reactor using different commercially available TiO2. The photocatalysts were characterized using BET, XRD and SEM.

Comparison of human hepatoma HepaRG cells with human and rat hepatocytes in uptake transport assays in order to predict drug induced hepatotoxicity [PDF]

open access: yes, 2013
Human hepatocytes are the gold standard for toxicological studies but they have several drawbacks, like scarce availability, high inter-individual variability, a short lifetime, which limits their applicability.

Molecularly imprinted TiO2 hybridized magnetic Fe3O4 nanoparticles for selective photocatalytic degradation and removal of estrone

open access: yes, 2014
As a widely used photocatalyst, titania (TiO2) enjoys significant advantages; however, it faces the severe challenge of poor selectivity. And interestingly, molecular imprinting gains great popularity, owing to its desired recognition specificity. Herein,

Regio- and Stereoselective Ruthenium Catalyzed Hydrovinylation of 1,3-Dienes: Application to the Generation of a 20S-Steroidal Sidechain [PDF]

open access: yes, 2003
The addition of ethylene to 1,3-dienes and 1-vinylcycloalkenes, catalyzed by two ruthenium complexes, proceeds in a regioselective fashion to afford 3-methyl-1,4-dienes as products. For a steroidal-based 1-vinylcycloalkene, the addition is stereospecific,

Measurement of Fecal Testosterone Metabolites in Mice: Replacement of Invasive Techniques [PDF]

open access: yes, 2020
Testosterone is the main reproductive hormone in male vertebrates and conventional methods to measure testosterone rely on invasive blood sampling procedures.
