Bisphenol Analog‐Induced Cytotoxicity: Unraveling Endoplasmic Reticulum (ER) Stress and Apoptotic Pathways

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) is increasingly replaced by structural analogs, yet their safety remains insufficiently characterized. This study investigated whether BPA and selected analogs, bisphenol AF (BPAF), bisphenol AP (BPAP), bisphenol P (BPP), and bisphenol E (BPE), induce cytotoxicity through activation of endoplasmic reticulum (ER) stress and ...

Bisphenol Analogs Downregulate the Self-Renewal Potential of Spermatogonial Stem Cells

The World Journal of Men's Health
Purpose: In this study, we investigated the effect of bisphenol-A (BPA) and its major analogs, bisphenol-F (BPF), and bisphenol- S (BPS), on spermatogonial stem cells (SSCs) populations using in vitro SSC culture and in vivo transplantation models ...

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

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

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

Exposure to Bisphenol A, Bisphenol F, and Bisphenol S in U.S. Adults and Children: The National Health and Nutrition Examination Survey 2013–2014

, 2018
Bisphenol F (BPF) and bisphenol S (BPS) are replacing bisphenol A (BPA) in the manufacturing of products containing polycarbonates and epoxy resins. Data on current human exposure levels of these substitutes are needed to aid in the assessment of their ...

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.
