Electronic address:

Environmentally persistent free radicals (EPFRs) in atmospheric fine particulate matters (PM) possess high bioactivity and result in severe health problems. The facile transformation of aromatic pollutants into EPFRs on montmorillonite (MMT), an important solid component in PM, is an activation of air pollutants into more toxic chemical species and also attributes to the secondary source of EPFRs in PM. In this study, the interfacial reactions of pentachlorophenol (PCP), a typical EPFR precursor in air pollution, on the Fe(III)-, Ca- and Na-MMT surfaces have been explored by the density functional theory (DFT) calculations using the periodic slab models.

Aquat Toxicol 2019 Jan 24;206:1-13. Epub 2018 Oct 24.

Anatomy, Physiology and Cell Biology, School of Veterinary Medicine, University of California, Davis, CA 95616, USA. Electronic address:

Altered transcription of calcium-dependent signaling cascades involving the ryanodine receptor (RyR) and mechanistic target of rapamycin (mTOR) in response to environmental exposures have been described in model vertebrates, including zebrafish, while the relevance for wild fishes remains unknown. To address this knowledge gap, we exposed the euryhaline model species Menidia beryllina (inland silversides) to the insecticide bifenthrin, a known modulator of calcium signaling. The main objectives of this study were to determine: (1) whether exposure of developing silversides to environmentally relevant concentrations of bifenthrin alters their behavior; and (2) whether behavioral changes correlate with altered expression of genes involved in RyR and mTOR-dependent signaling pathways.

Department of Functional Biology and Health Sciences, Faculty of Biology, University of Vigo, Campus Lagoas Marcosende, 36310 Vigo, Spain.

Paraoxon (POX) is an extremely neurotoxic organophosphorous compound (OP) which main toxic mechanism is the irreversible inhibition of cholinesterase. Although the cholinergic system has always been linked as responsible for its acute effects, experimental studies have suggested that the dopaminergic system also may be a potential target for OPs. Based on this, in this study, the acute intrastriatal effects of POX on dopaminergic neurotransmission were characterized in vivo using brain microdialysis in freely moving rats. Read More
