BACKGROUND Increasing environmental levels of brominated flame retardants raise concern about possible adverse effects, particularly through early developmental exposure. OBJECTIVE The objective of this research was to investigate neurodevelopmental mechanisms underlying previously observed behavioral impairments observed after neonatal exposure to(More)
BACKGROUND Brominated flame retardants, including the widely used polybrominated diphenyl ethers (PBDEs), have been detected in humans, raising concern about possible neurotoxicity. Recent research demonstrated that the hydroxylated metabolite 6-OH-BDE-47 increases neurotransmitter release by releasing calcium ions (Ca2+) from intracellular stores at much(More)
BACKGROUND/OBJECTIVE Polybrominated diphenyl ethers (PBDEs) and their hydroxylated (OH-) or methoxylated forms have been detected in humans. Because this raises concern about adverse effects on the developing brain, we reviewed the scientific literature on these mechanisms. DATA SYNTHESIS Many rodent studies reported behavioral changes after(More)
BACKGROUND Oxidative metabolism, resulting in the formation of hydroxylated polybrominated diphenyl ether (PBDE) metabolites, may enhance the neurotoxic potential of brominated flame retardants. OBJECTIVE Our objective was to investigate the effects of a hydroxylated metabolite of 2,2',4,4'-tetra-bromodiphenyl ether (BDE-47; 6-OH-BDE-47) on changes in the(More)
Polybrominated diphenyl ethers (PBDEs) are bioaccumulating flame retardants found in rising concentrations in human tissue. Epidemiological and animal studies have raised concern for their potential to induce developmental neurotoxicity (DNT). Considering the essential role of calcium homeostasis in neurodevelopment, PBDE-induced disturbance of(More)
Consistent high-quality of papers published in ''Toxicology in Vitro'' can only be maintained with the cooperation and dedication of a number of expert referees. The Editors would like to thank all those who have donated the hours necessary to review, evaluate and comment on manuscripts; their conscientious efforts have enabled the journal to maintain its(More)
Brominated flame retardants such as tetrabromobisphenol-A (TBBPA) may exert (developmental) neurotoxic effects. However, data on (neuro)toxicity of halogen-free flame retardants (HFFRs) are scarce. Recent in vitro studies indicated a high neurotoxic potential for some HFFRs, e.g., zinc stannate (ZS), whereas the neurotoxic potential of other HFFRs, such as(More)
A 331 and are uncertain about why community members are dying from what appear to the survivors to be unusual causes. Although Hrudey may feel this concern is misplaced or unfounded, that opinion does not reflect the feelings of those who live in Fort Chipewyan. The Alberta government's assertion that more extensive health studies are warranted (Chen 2009)(More)
