Transcription and induction profiles of three novel P450 genes in Liposcelis bostrychophila (Psocoptera: Liposcelididae).
J. Econ. Entomol. 105(2) , 560-72, (2012) The cDNAs of three novel P450 genes, CYP4CB1, CYP4CC1, and CYP4CD1 (GenBank accessions EU979550, EU979549, and EU979551, respectively), were sequenced and characterized from the psocid Liposcelis bostrychophila Badonnel (Psocoptera: Liposcelididae). CYP4CB1, ... |

Concentration-dependent interactions of the organophosphates chlorpyrifos oxon and methyl paraoxon with human recombinant acetylcholinesterase.
Toxicol. Appl. Pharmacol. 221(2) , 243-50, (2007) For many decades it has been thought that oxygen analogs (oxons) of organophosphorus insecticides phosphorylate the catalytic site of acetylcholinesterase by a mechanism that follows simple Michaelis-Menten kinetics. More recently, the interactions of at leas... |

Thionate versus Oxon: comparison of stability, uptake, and cell toxicity of ((14)CH(3)O)(2)-labeled methyl parathion and methyl paraoxon with SH-SY5Y cells.
J. Agric. Food Chem. 58(14) , 8460-6, (2010) The stability, hydrolysis, and uptake of the organophosphates methyl parathion and methyl paraoxon were investigated in SH-SY5Y cells. The stabilities of ((14)CH(3)O)(2)-methyl parathion ((14)C-MPS) and ((14)CH(3)O)(2)-methyl paraoxon ((14)C-MPO) at 1 microM ... |

Effects of the organophosphate paraoxon-methyl on survival and reproduction of Daphnia magna: importance of exposure duration and recovery.
Environ. Toxicol. Chem. 25(5) , 1196-9, (2006) The aim of this study was to determine the influence of exposure duration (1 h, 24 h, continuous) to paraoxon-methyl on the magnitude of lethal and sublethal effects, the shape of the concentration-response relationships and the recovery processes in Daphnia ... |

Effects of organophosphorus pesticides and their ozonation byproducts on gap junctional intercellular communication in rat liver cell line.
Food Chem. Toxicol. 45(10) , 2057-63, (2007) The effects of organophosphorus pesticides (OPs), oxons and their ozonation byproducts on gap junctional intercellular communication (GJIC) on cultured BRL cell line were investigated using scrape loading and dye transfer (SL/DT) technique. The neutral red up... |

Comparison of cholin- and carboxylesterase enzyme inhibition and visible effects in the zebra fish embryo bioassay under short-term paraoxon-methyl exposure.
Biomarkers 11(4) , 341-54, (2006) The acute zebra fish embryo test (Danio rerio Hamilton-Buchanan, 1822) is an accepted bioassay to assess the toxicity of waste water that may be used for the replacement of testing with adult fish. It is also suggested for chemical hazard characterization and... |

Modulation of the mutagenicity of heterocyclic amines by organophosphate insecticides and their metabolites.
Mutat. Res. 536(1-2) , 103-15, (2003) People are commonly exposed to organophosphorus ester (OP) insecticides through the treatment of pets, homes, lawns, gardens, workplaces and in commercial agriculture. Aromatic amines are another chemical class with wide human exposure particularly dietary he... |

A novel butyrylcholinesterase from serum ofLeporinus macrocephalus, a Neotropical fish
Biochimie 88(1) , 59-68, (2006) We show here that serum of piaussu, a Neotropical characin fish, has the highest butyrylcholinesterase activity so far described for humans and fish. To clarify whether this cholinesterase could protect piaussu against anticholinesterase pesticides by scaveng... |

Development of an indirect enzyme-linked immunosorbent assay for the organophosphorus pesticide paraoxon-methyl.
Immunol. Invest. 38(6) , 510-25, (2009) In the present study, the synthesis of hapten for the organophosphorus (OP) pesticide paraoxon-methyl was developed, with a spacer arm (aminocarboxylic acid) attached at the aromatic ring. It was conjugated to bovine serum albumin (BSA) for use as an immunoge... |

A high-throughput enzyme assay for organophosphate residues in milk.
Sensors (Basel.) 10(12) , 11274-86, (2010) A rapid, high-sensitivity, chemiluminescence (CL) enzyme assay for the determination of organophosphate (OP) residues in milk is presented. The assay for quantification of OP residues in milk is based on the inhibition of enzyme butyrylcholinesterase (BuChE).... |
