BACKGROUND Our study examines the effects of xenoestrogen mixtures on estradiol-induced non-genomic signaling and associated functional responses. Bisphenol-A, used to manufacture plastic consumer products, and nonylphenol, a surfactant, are estrogenic by a variety of assays, including altering many intracellular signaling pathways; bisphenol-S is now used as a bisphenol-A substitute. All three...

Bisphenol A (BPA) is being removed from many consumer products because of concerns about the chemical’s potential to disrupt the endocrine system. A chemical analog known as bisphenol S (BPS) has been adopted as an alternative in products such as water and baby bottles, thermal paper, and linings of metal cans. In this issue of EHP, a new study shows that BPS has nearly identical impacts on the...

OBJECTIVE To investigate associations between serum bisphenol A (BPA) concentrations and follicular response to exogenous ovary stimulation. DESIGN Fasting serum was prospectively collected on the day of oocyte retrieval and assessed for unconjugated BPA using high-performance liquid chromatography with Coularray detection. Multivariable linear regression and negative binomial regression were...

The paper shows a procedure for selecting the control method parameters (factors) to obtain preset ‘analytical target profile’ when liquid chromatographic technique is going be carried out simultaneous determination of five bisphenols (bisphenol-A, bisphenol-S, bisphenol-F, bisphenol-Z and bisphenol-AF), some them regulated by European Union. has three steps. first consists building D-optimal c...
