    A CFD model for the smouldering combustion of the cellulosic substrate during the ignition propensity test

    GUINDOS P.(1); PATEL A.(1,2); KOLB T.(1)
    (1) Fraunhofer Institute for Molecular Biology and Applied Ecology IME, Aachen, Germany; (2) TU Braunschweig, Braunschweig, Germany
    An experimental and numerical investigation was conducted to characterise the influence of the cellulosic substrate used to assess the ignition propensity (IP) of cigarettes. The objective was to better understand the poor repeatability of the test and ...

    CSEO – The cigarette smoke exposure ontology

    YOUNESI E.(1), COGGINS C.(2); ANSARI S.(3); HOENG J.(3); PEITSCH M.(3); HOFMANN-APITIUS M.(1)
    (1) Fraunhofer Institute for Algorithms and Scientific Computing SCAI, Sankt Augustin, Germany; (2) Carson Watts Consulting, King, NC, USA; (3) Philip Morris International R&D, Neuchâtel, Switzerland
    In the past years, significant progress has been made in the development and use of experimental settings for collection of massive and precise experimental data on tobacco exposure and the diseases induced by it. Despite the growing number of such data, ...

    Influence of the origin of the cigarette paper cellulose on the smoke chemical composition and "in vitro" toxicity tests on mainstream cigarette smoke

    TROUDE V.; ACHARD S.; DESTRUHAUT S.; HAOND C.; SARABIA J.
    Altadis - Imperial Tobacco Group, Research Center, Fleury les Aubrais, France
    Nowadays, cigarette paper is made out of cellulose coming from different sources. Wood cellulose is currently very often used, but cellulose coming from different textile plants like hemp, flax, etc. were used primarily in the past and are still present ...

    Gene expression analysis of human lung cells treated with cigarette smoke

    ACHARD S.; VERRON T.; SEVESTRE O.; DUMERY B.
    Altadis - Imperial Tobacco Group, Research Center, Fleury les Aubrais, France
    Gene expression profiling is considered as a promising tool that may identify more sensitive, mechanism-based biomarkers. Such an experimental approach should provide a better understanding of the impact of chemical compounds on the intracellular ...
