Carbon fiber brush electrode as a novel substrate for atmospheric solids analysis probe (ASAP) mass spectrometry: Electrochemical oxidation of brominated phenols.

Jana Skopalová et al.

Analytica chimica acta, 999, 60-68 (2017-12-20)

A carbon fiber brush electrode (CFBE) was newly designed and used as a substrate for both controlled potential electrolysis and atmospheric solids analysis probe (ASAP) mass spectrometry. Electropolymerized and strongly adsorbed products of electrolysis were directly desorbed and ionized from

Tetrabromobisphenol A, terabromobisphenol S and other bromophenolic flame retardants cause cytotoxic effects and induce oxidative stress in human peripheral blood mononuclear cells (in vitro study).

Anna Włuka et al.

Chemosphere, 261, 127705-127705 (2020-07-31)

Brominated flame retardants (BFRs) are the compounds used in the industry in order to decrease flammability of various everyday products. The use of BFRs leads to migration of these substances into the environment, which results in the exposure of humans

Evaluation of the Effect of Selected Brominated Flame Retardants on Human Serum Albumin and Human Erythrocyte Membrane Proteins.

Monika Jarosiewicz et al.

International journal of molecular sciences, 21(11) (2020-06-04)

Brominated flame retardants (BFRs) have been using to reduce the flammability of plastics contained in many products, such as household articles, furniture, mattresses, textiles or insulation. Considering the fact that these compounds may be released into the environment leading to

Structure of human transthyretin complexed with bromophenols: a new mode of binding.

M Ghosh et al.

Acta crystallographica. Section D, Biological crystallography, 56(Pt 9), 1085-1095 (2000-08-25)

The binding of two organohalogen substances, pentabromophenol (PBP) and 2,4,6-tribromophenol (TBP), to human transthyretin (TTR), a thyroid hormone transport protein, has been studied by in vitro competitive binding assays and by X-ray crystallography. Both compounds bind to TTR with high

Pentabromophenol suppresses TGF-β signaling by accelerating degradation of type II TGF-β receptors via caveolae-mediated endocytosis.

Chun-Lin Chen et al.

Scientific reports, 7, 43206-43206 (2017-02-24)

Pentabromophenol (PBP), a brominated flame retardant (BFR), is widely used in various consumer products. BFRs exert adverse health effects such as neurotoxic and endocrine-disrupting effects. In this study, we found that PBP suppressed TGF-β response by accelerating the turnover rate

The Affinity of Brominated Phenolic Compounds for Human and Zebrafish Thyroid Receptor β: Influence of Chemical Structure.

Erin M Kollitz et al.

Toxicological sciences : an official journal of the Society of Toxicology, 163(1), 226-239 (2018-02-07)

Brominated phenolic compounds (BPCs) are found in the environment, and in human and wildlife tissues, and some are considered to have endocrine disrupting activities. The goal of this study was to determine how structural differences of 3 BPC classes impact

Investigations on acute hepato- and nephrotoxicity of pentabromophenol.

J A Szymańska et al.

International journal of occupational medicine and environmental health, 8(3), 245-254 (1995-01-01)

Pentabromophenol (PBP) was administered in a single or repeated doses to mice or in a single dose to rats. Slight changes were noted in the level of SGPT in mice serum and GSH in the liver, with a more pronounced

Mitochondrial-related effects of pentabromophenol, tetrabromobisphenol A, and triphenyl phosphate on murine BV-2 microglia cells.

Christine Bowen et al.

Chemosphere, 255, 126919-126919 (2020-05-14)

The predominant reliance on bromated flame retardants (BFRs) is diminishing with expanded use of alternative organophosphate flame retardants. However, exposure related issues for susceptible populations, the developing, infirmed, or aged, remain given environmental persistence and home-environment detection. In this regard

Molecular characterization of brominated persistent pollutants using extended X-ray absorption fine structure (EXAFS) spectroscopy.

Magnus Bergknut et al.

Analytical and bioanalytical chemistry, 390(3), 921-928 (2007-11-14)

X-ray absorption fine structure (EXAFS) spectroscopy spectra were collected for three brominated persistent pollutants: 6-bromo-2,4,5-trichlorophenol (BrTriClP), pentabromophenol (PentaBrP) and 3,3',5,5'-tetrabromobisphenol A (TBBA). The substances were selected to be symmetrical (BrTriClP and TBBA) or asymmetrical (PentaBrP) with respect to the atomic

Changes in the activities of antioxidant enzymes and reduced glutathione level in human erythrocytes exposed to selected brominated flame retardants.

Monika Jarosiewicz et al.

Chemosphere, 227, 93-99 (2019-04-16)

Currently, more and more concerns are related to oxidative stress appearing in cells as a result of xenobiotics action. It has been found that selected brominated flame retardants (BFRs) can cause reactive oxygen species (ROS) induction at environmental concentrations. Excessive
