    Indoor air chemistry (IAC): comparative study between conventional cigarette and heat-not-burn technology

    GOUJON C.; MAEDER S.
    Philip Morris International R&D, Neuchâtel, Switzerland
    Philip Morris International (PMI) is developing products with the potential to reduce the risk associated with smoking. The Electrically Heated Tobacco System (EHTS) operates by heating a tobacco stick with a holder at a controlled temperature. By heating ...

    Evaluating the genotoxicity of tobacco smoke-derived aerosols using the flow cytometry-based in vitro micronucleus assay

    POULEAU B.; SMART D.J.; McHUGH D.
    Philip Morris International R&D, Philip Morris Products S.A., Neuchâtel, Switzerland
    The in vitro micronucleus (MN) assay is used to assess the genotoxic potential of a test substance by measuring the induction of micronuclei in cultured mammalian cells. The flow cytometry-based assay (in vitro MicroFlow ® kit, Litron Laboratories, USA) ...
