The Effects of Estrogen (E2), Bisphenol A (BPA), Bisphenol S (BPS), and Bisphenol F (BPF) on the Proliferation of MCF-7 Cells

, 2016
Endocrine disrupting compounds (EDCs) are chemicals that disturb the endocrine system and exhibit adverse effects throughout the body. EDCs exert their effects by displaying hormone-like activity and can act as agonists or antagonists to normal hormonal ...

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Corrosion‐Protection of T122 Steel Using g‐C3N5‐Embedded Epoxy Coatings

Materials and Corrosion, EarlyView.
Study evaluates g‐C3N5 (CN) reinforced epoxy coatings on T122 steel in NaCl and H2SO4. Electrochemical tests revealed that 2% loading maximizes corrosion resistance by blocking pores and limiting ion diffusion, increasing Rp and Rn. Optimized CN content enhances epoxy coating performance overall system durability material. ABSTRACT Corrosion‐protection

Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

Macromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

The Endocrine Disrupting Compounds Bisphenol‐A and α‐Zeranol Mimic the Estrogen Transcriptional Program to Promote Proliferation and Stemness in Breast Cancer Cells

Molecular Carcinogenesis, EarlyView.
ABSTRACT Excessive activation of the estrogen receptor (ER) drives proliferation, progression, and the formation of breast cancer stem cells (CSCs) in ER‐positive breast cancer. Estrogenic endocrine disrupting compounds (EDCs) found in plastics, water, and food are also able to bind to the ER.

Microbiological safety in the reuse of materials in home enteral nutrition: A quantitative in vitro experimental study

Nutrition in Clinical Practice, EarlyView.
Abstract Introduction In home enteral nutrition (HEN), the reuse of packaging and administration materials beyond the recommended period, combined with inadequate hygiene practice, increase the risk of microbiological contamination. This study assessed the risk through a simulation that reproduced real‐world usage conditions and hygiene practices ...
