Photochemical Formation of Hydroxylated Polybrominated Diphenyl Ethers (OH-PBDEs) from Polybrominated Diphenyl Ethers (PBDEs) in Aqueous Solution under Simulated Solar Light Irradiation.
Environ. Sci. Technol. 49 , 9092-9, (2015) Hydroxylated polybrominated diphenyl ethers (OH-PBDEs) are of great concern due to their higher toxicity compared to PBDEs. However, the abiologic process whereby PBDEs are converted to OH-PBDEs in the aquatic environment is not well understood. To explore th... |

Gas chromatographic-mass spectrometric analysis of sulfur mustard-plasma protein adducts: validation and use in a rat inhalation model.
J. Anal. Toxicol. 32(1) , 37-43, (2008) Sulfur mustard (HD) is an alkylating agent that reacts rapidly with macromolecular targets resulting in the formation of stable adducts providing depots for markers of exposure. The purpose of this study was to validate an analytical procedure for detection o... |

Improvements in the methodology of monitoring sulfur mustard exposure by gas chromatography-mass spectrometry analysis of cleaved and derivatized blood protein adducts.
J. Anal. Toxicol. 32(1) , 31-6, (2008) An analytical method for determining exposure to 2,2'-dichlorodiethyl sulfide (sulfur mustard, HD) has been enhanced. The method is based on the cleavage of adducted HD (protein-hydroxyethylthioethyl esters) to produce thiodiglycol. Following cleavage, a deut... |

Analysis of dextrorphan, a metabolite of dextromethorphan, using gas chromatography with electron-capture detection.
J. Pharmacol. Toxicol. Methods 41(4) , 143-6, (1999) Dextromethorphan, a constituent of many over-the-counter cough syrups, is used as a probe drug for phenotyping subjects for their cytochrome P450 2D6 (CYP2D6) enzyme activity and for measuring CYP2D6 activity of preparations such as microsomes. In such studie... |

Evidence of estrone-sulfate uptake modification in young and middle-aged rat prostate.
J. Steroid Biochem. Mol. Biol. 152 , 89-100, (2015) High plasma exposure to estrogens is often associated with prostate cancer. Reducing this phenomenon may present therapeutic benefits. The involvement of estrone sulphate (E1S), the most abundant circulating estrogen in men, has been partially studied in this... |

Quantitation of 1-stearoyl-2-arachidonoyl-sn-3-glycerol in human basophils via gas chromatography-negative ion chemical ionization mass spectrometry.
Anal. Biochem. 236(2) , 309-21, (1996) Investigation of the role of diacylglycerol molecular species in signal transduction in human basophils has been impeded by the lack of an assay method with adequate sensitivity and selectivity. Conversion of 1-stearoyl-2-arachidonoyl-sn-3-glycerol to the pen... |
