Biotransformation of bisphenol AF to its major glucuronide metabolite reduces estrogenic activity. [PDF]

PLoS One, 2013
Bisphenol AF (BPAF), an endocrine disrupting chemical, can induce estrogenic activity through binding to estrogen receptor (ER). However, the metabolism of BPAF in vivo and the estrogenic activity of its metabolites remain unknown. In the present study, we identified four metabolites including BPAF diglucuronide, BPAF glucuronide (BPAF-G), BPAF ...

Cure Kinetics and Chemorheological Modeling of a Transesterification‐Based Epoxy/Anhydride Vitrimer

Journal of Applied Polymer Science, Volume 143, Issue 7, February 15, 2026.
Cure kinetics and chemorheological model predictions of experimental reaction rate and chemoviscosity evolutions. ABSTRACT This study presents the cure kinetics, glass transition temperature (T g ) and chemoviscosity models for an epoxy vitrimer synthesized from DGEBA, methylhexahydrophthalic anhydride (MHHPA), and triethanolamine (TEOA).

Analogy or fallacy, unsafe chemical alternatives: Mechanistic insights into energy metabolism dysfunction induced by Bisphenol analogs in HepG2 cells

Environment International, 2023
Bisphenol analogs (BPs) are widely used as industrial alternatives for Bisphenol A (BPA). Their toxicity assessment in humans has mainly focused on estrogenic activity, while other toxicity effects and mechanisms resulting from BPs exposure remain ...

Steroid Hormones and Endocrine Disruptors: Recent Advances in Receptor–Mediated Actions [PDF]

, 2017
It has been accepted that receptor-mediated action of steroid hormones depends on both the receptor and the hormonal level. The mechanism of transcription by steroid receptors is mediated by cofactors, which function as co-activators or co ...

Epidemiological Comparative Study on Contact Sensitisations in Woodworkers With Occupational Dermatitis: Patch Test Data of the Information Network of Departments of Dermatology, 1999 to 2023

Contact Dermatitis, Volume 94, Issue 2, Page 125-136, February 2026.
The data demonstrates that allergic contact dermatitis is common in WW with OD. The most important allergens include resins (including epoxy resin) and plant‐derived substances (including colophonium). The high share of WW with allergic contact dermatitis and face dermatitis hampers preventive efforts.

Soluble Molecularly Imprinted Polymer-Based Potentiometric Sensor for Determination of Bisphenol AF [PDF]

Analytical Chemistry, 2017
Molecularly imprinted polymer (MIP)-based polymeric membrane potentiometric sensors have been successfully developed for determination of organic compounds in their ionic and neutral forms. However, most of the MIP receptors in potentiometric sensors developed so far are insoluble and cannot be well dissolved in the polymeric membranes.

Predicting bioconcentration factor and estrogen receptor bioactivity of bisphenol a and its analogues in adult zebrafish by directed message passing neural networks

Environment International, 2022
The bioconcentration factor (BCF) is a key parameter for bioavailability assessment of environmental pollutants in regulatory frameworks. The comparative toxicology and mechanism of action of congeners are also of concern.

Effect of Dissolved Hydrogen on Polyamide 11: Observation During Hydrogen Desorption Process After Decompression at Atmospheric Pressure

Journal of Applied Polymer Science, Volume 143, Issue 3, January 15, 2026.
Dissolved hydrogen‐induced plasticization of polyamide 11 (PA11) detected as a decrease in flexural modulus (E f) using Cyclic Three‐Point Bending (Cyc‐3PB). ABSTRACT The effect of dissolved hydrogen on polyamide 11 (PA11) after decompression from a 90 MPa hydrogen gas environment was investigated. Structural analyses using wide‐angle X‐ray diffraction
