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

Diastereoselective Synthesis and Biological Evaluation of Spiro[chromane-2,4′-pyrimidin]-2′(3′H)-ones as Novel Antimicrobial and Antioxidant Agents

Molecules
This study reports an improved diastereoselective synthesis of substituted spiro[chromane-2,4′-pyrimidin]-2′(3′H)-ones via the acid-catalyzed condensation of 6-styryl-4-aryldihydropyrimidin-2-ones with resorcinol, 2-methylresorcinol, and pyrogallol.

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 ...

Polymer and Polymer Composite‐Based Electrochemical Sensors for Real‐Time Detection of River Water Targeted Endocrine Disruptors

Macromolecular Symposia, EarlyView.
ABSTRACT Endocrine‐disrupting chemicals (EDCs) are pervasive environmental contaminants that interfere with hormone function and pose significant risks to ecosystems and human health. Their presence in river water necessitates sensitive, selective, and real‐time detection methods for effective monitoring and mitigation.

Reproductive effects in two species of native freshwater gastropod mollusc exposed to 17β-oestradiol or an environmentally relevant mixture of oestrogenic chemicals in outdoor mesocosms

, 2009
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Recent evidence suggests that molluscs may be sensitive to the effects of endocrine disrupting chemicals (EDCs) in a similar manner to vertebrates, such as

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.

099 | Mechanistic insights into the ecotoxicity of bisphenol analogues and their mixtures in marine mussels: oxidative stress and neuro-immune responses

Journal of Biological Research
Bisphenol analogues such as bisphenol F (BPF) and bisphenol S (BPS) are increasingly used as substitutes for bisphenol A and are now widely detected in marine environments, yet their ecotoxicological effects at environmentally realistic concentrations ...

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 ...

Performance of Glass Fiber Composites With Plastic‐Waste Pyrolysis Char as Filler

Polymer Composites, EarlyView.
Valorisation of mixed plastic waste into carbonaceous char via pyrolysis, its integration as a microfiller in epoxy/E‐glass (GFRP) laminates, and characterisation to assess composite performance as a function of filler loading. ABSTRACT Plastic pyrolysis offers circular solutions for mixed plastic waste but leaves a carbonaceous char that is often ...
