    Analysis of protein modifications induced by cigarette smoke

    LE FAOUDER P.; EMAMI I.; ROLANDO C.; TOKARSKI C.
    University of Sciences and Technologies of Lille, Laboratory of Organic and Macromolecular Chemistry, CNRS IMR 8009, Villeneuve d'Ascq, France
    We will present here work done on identification of protein modifications induced by cigarette smoke, particularly protein oxidation and nitration, using on-line nanoLC, ECD hyphenation on a FT-ICR instrument (Fourier Transform- Ion Cyclotron Resonance). ...

    Identification and quantification of free radical content in cigarette smoke using nanoLC nano ESI FT-ICR MS/MS

    LE FAOUDER P.; TOKARSKI C.; EMAMI I.; ROLANDO C.
    University of Sciences and Technologies of Lille, Laboratory of Organic and Macromolecular Chemistry, CNRS IMR 8009, Villeneuve d'Ascq, France
    Cigarette smoke is a highly complex aerosol of several thousand chemical substances of which free radicals, short-life time molecules, are present in high concentration. In order to identify and quantify them, we have developed a new methodology based on ...

    Proteomics study of the influence of free radicals contents in cigarette smoke on culture cells

    LE FAOUDER P.; TOKARSKI C.; EMAMI I.; ROLANDO C.
    University of Sciences and Technologies of Lille, Laboratory of Organic and Macromolecular Chemistry, CNRS IMR 8009, Villeneuve d'Ascq, France
    The influence of free radicals from cigarette smoke on MCF-7 cell lines has been investigated in our laboratory using proteomics study. The work presented here will expose the comparison between untreated cells and cells incubated with conventional ...

    Feature selection from near infrared spectra using genetic algorithms for tobacco blend recognition

    FIGUERES G.; DE SOUZA S.; REYNES C.; SABATIER R.; VIDAL B.
    Altadis Research Centre, Fleury-les-Aubrais, France
    Near infrared reflectance spectroscopy has proved to be very useful for predicting concentrations of chemical compounds in tobacco, classification or pattern recognition of cigarette blends. The resulting measurement of a sample is a whole reflectance ...

    How representative of the human smoking behaviour would be the new alternative smoking regimes? A first attempt of assessment

    MARCHAND V.; TESSIER C.; DUMERY B.
    Altadis Research Centre, Fleury-les-Aubrais, France
    The ISO or FTC smoking conditions (35 mL- 2 s puffs, 1 puff per minute) have been more and more criticized during the last decade, especially because they would not reflect the human smoking behaviour. Their main objective was not to predict the exact ...

    A mixture experimental design with six variables and the effects on smoke components:1 - Presentation of this experimental design and of some initial results on physical characteristics of cigarettes and blends

    VIDAL B.; FIGUERES G.; BIESSE J.P.; BREGEON B.; LOUVET F.; MUZELLEC L.
    Altadis Research Centre, Fleury-les-Aubrais, France
    The objective of this paper is to examine the effects of six tobacco components on the chemical and physical characteristics of blends and cigarettes and particularly on the mainstream smoke yields. First of all, we will develop the philosophy of this ...

    A mixture experimental design with 6 variables and the effects on smoke components:2 - Hoffmann analytes behaviour through a mixture experimental design

    FIGUERES G.; VIDAL B.; BIESSE J.P.; BREGEON B.; LOUVET F.; MUZELLEC L.
    Altadis Research Centre, Fleury-les-Aubrais, France
    Today in the tobacco industry, one of the main scientific challenges is to understand the formation of some smoke compounds ("Hoffmann analytes"). For several years, work has been conducted in order to know the influence of cigarette design ...
