    Impact of cigarette paper parameters on smoke yields of cigarettes with different circumferences

    MÜLLER P.; GLEINSER M.; BACHMANN S.; VOLGGER D.
    Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria
    Cigarettes with reduced circumference are very popular in several markets. Over the last decade a significant growth rate has been observed worldwide. Changing the circumference has an influence on the physical properties of the unlit cigarette and ...

    Distinct gene expression changes in peripheral blood mononuclear cells exposed to combustible versus non-combustible tobacco product preparations

    TRAN N.Q.(1); ARIMILLI S.(2); MADAHIAN B.(3); HOMAYOUNI R.(3); PRASAD G.L.(1)
    (1) RAI Services, Winston-Salem, NC, USA; (2) Wake Forest University, Winston-Salem, NC, USA; (3) Quire Inc., Memphis, TN, USA
    Cigarette smoking exerts diverse physiological effects including immune suppression. Existing epidemiological data show that consumption of smokeless tobacco products, such as moist snuff, is less harmful relative to smoking. We previously demonstrated ...

    Differential gene expression and functional responses in peripheral blood mononuclear cells pretreated with combustible and non-combustible tobacco products

    TRAN Q.T.(1); ARIMILLI S.(2); LIU Gang(1); MAKENA P.(1); PRASAD G.L.(1)
    (1) RAI Services Company, Winston-Salem, NC, USA; (2) Wake Forest School of Medicine, Winston-Salem, NC, USA
    Chronic smoking is known to alter immune responses, which compromises tumor surveillance and host defense against microbial infections. We previously showed that smokers (SMK) exhibit distinct peripheral blood mononuclear cell (PBMC) gene expression ...

    Identification of genetic determinants controlling cadmium accumulation in tobacco

    BERTRAND J.(1); JULIO E.(2); COTUCHEAU J.(2); DORLHAC DE BORNE F.(2); BERTHOMIEU P.(1)
    (1) UMR de Biochimie et Physiologie Moléculaire des Plantes, INRA/CNRS/Montpellier SupAgro/Université Montpellier, Montpellier, France; (2) Imperial Tobacco Limited, Leaf Research, La Tour, Bergerac, France
    Cadmium is a toxic heavy metal naturally absorbed and accumulated by plants. It is present in tobacco (Nicotiana tabacum) leaves and potentially in the smoke of cigarettes. Reducing the cadmium content in leaves of tobacco plants requires a better ...

    Many recessive resistances against potyviruses are mediated by eukaryotic translation initiation factors (eIF4E). In tobacco, the va resistance gene commonly used to control PVY corresponds to a large (almost 1Mb) deletion affecting a copy of eIF4E ...

    Di@gnoPlant® Tobacco: a mobile tool to identify tobacco diseases

    BLANCARD D.(1); ARMAND J.M.(1); MARIGNAC E.(2)
    (1) INRA, UMR Santé et Agroécologie de la Vigne, ISVV - IFR103, Villenave-d'Ornon, France; (2) CORESTA, Paris, France
    In order to reduce the use of crop protection agents in the field, the early and reliable identification of diseases and the detection of emergent pests have proven to be crucial stages in plant protection. An early diagnosis enables implementation of the ...

    Influence of storage conditions on smoke yields and optical appearance of cigarettes

    GLEINSER M.; BACHMANN S.; VOLGGER D.
    Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria
    Chemical and physical changes of the cigarette paper can occur during the storage of cigarettes. These changes may have an influence on the smoke yields, the taste of a cigarette and also on the optical properties of the cigarette and the ash appearance ...
