    Lowering TSNAs through nitrite reductase activity

    DAVENPORT S.E.; FORSYTH K.; TULLY L.; LISTER R.; LE LAY P.; MAUNDERS M.; SANCHEZ-TAMBURRINO J.P.
    Advanced Technologies Ltd., Cambridge, UK (holding of British American Tobacco Ltd.)
    Tobacco specific nitrosamines (TSNAs) are compounds in tobacco that have been shown to be carcinogenic. TSNAs are formed by the nitrosation of tobacco alkaloids with the main nitrosating agent believed to be nitrite. High levels of nitrate accumulation ...

    Use of an EpiOralTM human tissue model for testing of substances for oral irritancy in vitro

    JAI T.S.; DELVES S.J.; FAUX S.P.; KUMARAVEL T.S.; NEILSON L.R.; MEREDITH C.
    Advanced Technologies Ltd., Cambridge, UK
    The EpiOralTM tissue model consists of normal human keratinocytes differentiated to form a multilayered tissue. The phenotype is analogous to human oral epithelium in vivo providing the opportunity for in vitro irritancy testing on human tissue. This ...
