    Downregulation of a putative nitrate transporter gene substantially reduces the accumulation of TSNAs in air-cured tobaccos

    GOEPFERT S.(1); BOVET L.(1); LU J.(2); CAMPANONI P.(1); LEWIS R.S.(2); DEWEY R.E.(2)

    The influence of Nicotiana alata-derived introgression on plant malformations of tobacco breeding lines resistant to tomato spotted wilt virus

    KORBECKA-GLINKA G.(1); TROJAK-GOLUCH A.(1); DOROSZEWSKA T.(1); GOEPFERT S.(2)
    (1) Institute of Soil Science and Plant Cultivation - State Research Institute, Pulawy, Poland; (2) Philip Morris Products S.A. (part of Philip Morris International group of companies), PMI R&D, Neuchâtel, Switzerland
    Tomato spotted wilt virus (TSWV) is one of the most destructive viruses for tobacco cultivation. Cultivar “Polalta” carries a resistance gene introgressed from a wild species, Nicotiana alata, but the use of this cultivar in breeding is hampered by ...

    Assessing the cytotoxicity of e-liquids without the use of the neutral red uptake assay

    McHUGH D.; CUDAZZO G.; VANSCHEEUWIJCK P.
    Philip Morris Products S.A. (part of Philip Morris International group of companies), PMI R&D, Neuchâtel, Switzerland
    As part of the pre-clinical assessment performed for consumer products in the tobacco industry, an in vitro assessment of a tobacco product’s cytotoxicity was performed using the neutral red uptake (NRU) assay. Since 2004, the CORESTA In Vitro Task Force ...

    Comparison of potential health risks of combustible, heat-not-burn, and electronic cigarettes

    LIU C.; MARANO K.
    RAI Services Company, Winston-Salem, NC, U.S.A.
    Given U.S. Food and Drug Administration (FDA) regulation of tobacco products via the Family Smoking Prevention and Tobacco Control Act, there is a growing recognition of the need for evidence to assist both applicants and the FDA in making determinations ...

    (1) Ramboll U.S. Corp., Amherst, MA, U.S.A.; (2) RAI Services Co., Winston-Salem, NC, U.S.A.
    There are a number of dynamic population models that can be used to quantify the overall population health effects of beneficial and/or harmful changes in tobacco use patterns. These models can be broadly categorized as either following a single birth ...

    Multi-dimensional tipping point analyses: Assessing simultaneous shifts in tobacco use patterns from a higher to a lower risk product

    BACHAND A.(1); SULSKY S.(1); CURTIN G.(2)
    (1) Ramboll U.S. Corp., Amherst, MA, U.S.A.; (2) RAI Services Co., Winston-Salem, NC, U.S.A.
    The Dynamic Population Modeler (DPM(+1)) employs a birth cohort framework to estimate effects on population mortality if tobacco use patterns shift from a higher- to lower-risk product. DPM(+1) allows for evaluation of changes in use patterns within the ...
