Identification of stable cytotoxic factors in the gas phase extract of cigarette smoke and pharmacological characterization of their cytotoxicity.
Toxicology 314(1) , 1-10, (2013) Smoking is a major risk factor for atherosclerotic vascular diseases, but the mechanism for its genesis is unknown. We have recently shown that the gas phase of cigarette smoke (nicotine- and tar-free cigarette smoke extract; CSE) likely to reach the systemic... |

Analysis of 3'-phosphoglycolaldehyde residues in oxidized DNA by gas chromatography/negative chemical ionization/mass spectrometry.
Chem. Res. Toxicol. 16(12) , 1560-6, (2003) Deoxyribose oxidation in DNA represents a biologically important facet of oxidative DNA damage that gives rise to protein-DNA cross-links and base adducts. Toward the goal of quantifying deoxyribose oxidation chemistry in cells, we report a method for the qua... |

Determination of carbonyl compounds in pool water with O-(2,3,4,5,6-pentafluorobenzyl)hydroxyamine hydrochloride and gas chromatographic-tandem mass spectrometric analysis.
J. Chromatogr. A. 1046(1-2) , 293-6, (2004) To avoid microbiological decay pool water is disinfected, a procedure which results into a lot of disinfection by-products, like carbonyl compounds, as well as a large number of others. The carbonyl compounds dissolved in pool water were derivatisized with O-... |
