    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 ...

    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 ...

    Combustible and smokeless tobacco product preparations differentially regulate calcium mobilization in the human leukemic HL60 cell line

    MAKENA P.(2); ARIMILLI S.(1); DAMRATOSKI B.E.(1); PRASAD G.L.(2)
    (1) Wake Forest University School of Medicine, Department of Microbiology & Immunology, Winston-Salem, NC, U.S.A.; (2) RAI Services Co., Winston-Salem, NC 27102, U.S.A.
    Increased calcium (Ca 2+) mobilization is central to leukocyte signaling and for regulation of immune responses. Although evidence suggests that cigarette smoking affects several biological functions including inflammatory responses, how the use of ...

    Role of polyamines in leaf ripening of low alkaloid tobacco varieties

    NÖLKE G.(1); VOLKE D.(1); CHUDOBOVA I.(1); HOUDELET M.(1); LUSSO M.(2); FREDERICK J.(2); WAREK U.(2); STRICKLAND J.(2); XU D.(2); FISCHER R.(1); SCHINKEL H.(1); SCHILLBERG S.(1)
    (1) Fraunhofer Institute for Molecular Biology and Applied Ecology IME, Aachen, Germany; (2) Altria Client Services LLC, Research, Development and Regulatory Affairs, Richmond, VA, U.S.A.
    Traditional breeding and molecular approaches have been used to develop tobacco varieties with reduced nicotine and secondary alkaloid levels. However, low-alkaloid (LA) tobacco varieties often show impaired leaf ripening and senescence leading to poor ...

    (1) Altria Client Services LLC, Research, Development and Regulatory Affairs, Richmond, VA, U.S.A.; (2) Fraunhofer Institute for Molecular Biology and Applied Ecology IME, Muenster, Germany
    Tobacco plants exhibit strong apical dominance that effectively inhibits axillary bud development. However, upon shoot apical meristem removal (topping), loss of apical dominance quickly allows axillary buds to grow (suckers) resulting in yield loss and ...
