    Development of a method for the estimation of mouth level exposure to nicotine from electronic cigarettes

    KUBOTA T.; SUZUKI T.; SHIBATA T.
    Japan Tobacco Inc., R&D Group, Scientific Product Assessment Center, Yokohama, Kanagawa, Japan
    Mouth level exposure (MLE) assessments are valuable in helping interpret, as well as potentially predict, the results from clinical investigations, such as biomarkers of exposure studies. To date, methods to estimate nicotine-MLE from electronic cigarette ...

    The retention of nicotine from a new type of heated tobacco product in human respiratory tracts

    SUZUKI T.; YUKI D.; KITAGAWA M.; SHIBATA T.
    Japan Tobacco Inc., R&D Group, Scientific Product Assessment Center, Yokohama, Kanagawa, Japan
    Nicotine is the major alkaloid in tobacco leaf and therefore present in tobacco products. Previous studies suggest that absorption sites of nicotine in human respiratory tracts affect nicotine pharmacokinetics. This study investigated the retention of ...

    Comparison of in vitro and in vivo exposed chemical levels following cigarette smoke exposure

    ISHIKAWA S.; SUZUKI T.; NAGATA Y.
    Japan Tobacco Inc., Tobacco Science Research Center, Yokohama, Kanagawa, Japan
    For the risk assessment of airborne chemicals, a variety of in vitro direct exposure systems have been developed and applied in the biological evaluation of cigarette smoke. In direct exposure systems, cells are exposed to cigarette smoke as an aerosol at ...

    Theory of estimating tobacco materials breakage Vol. 3 (Development of the numerical simulation of tobacco cut-rag breakage)

    SAKUMA Y.; SUZUKI T.; FUKUCHI J.; MASHINO S.
    Japan Tobacco Inc., Manufacturing Technology Research & Development Div., Tokyo, Japan.
    Tobacco materials are progressively damaged and broken by the external forces of manufacturing machinery and equipment throughout the entire process. Recently, with the increase in the speed of equipment, the level of tobacco materials' breakage has ...

    The theory of estimating tobacco materials breakage Vol. 2

    SUZUKI T.; SAKUMA Y.; FUKUCHI J.; MASHINO S.
    Japan Tobacco Inc., Manufacturing Technology Research & Development Div., Tokyo, Japan.
    The breakage of tobacco cut-rags appears in the tobacco manufacturing process, and it causes some quality problems and loss of tobacco materials. The authors have already established and verified the theory of tobacco materials breakage (presented in 2001 ...

    Development of novel lines resistant to tobacco yellow spotted streak disease by ion beam irradiation

    SUZUKI T.; TANAKA A.; WATANABE H.
    Japan Tobacco Inc., Leaf Tobacco Research Laboratory, Oyama, Tochigi, Japan.
    Ion beams have a higher LET than X and gamma rays. The irradiation of ion beams has a high potential for inducing in mutant plants novel characters that might not be obtained by commonly used mutagens. Tobacco yellow spotted streak disease caused by ...
