    Influence of the time of and stirring rate during the first step of synthesis of SBA-15 on its catalytic effect for reducing toxicants concentration in tobacco smoke

    JUÁREZ-SERRANO N.; ASENSIO-MORANT J.; MARTÍNEZ-CASTELLANOS I.; BERENGUER D.; BLASCO I.; BELTRÁN M.I.; MARCILLA A.
    University of Alicante, Alicante, Spain
    Certain mesoporous materials can modify notably the composition of smoke tobacco, since they can act as catalysts and/or adsorbents allowing to reduce the toxic and carcinogenic compounds of the smoke. However, the properties of the catalysts strongly ...

    Effect of SBA-15 morphology in the composition of the mainstream tobacco smoke

    MARTÍNEZ-CASTELLANOS I.; MARCILLA A.; BELTRÁN M.I.; BERENGUER D.; BLASCO I.; JUAREZ N.; ASENSIO J.; CALABUIG E.
    University of Alicante, Alicante, Spain
    Mesoporous silica materials, such as SBA-15, are attracting increasing interest in the last years. Our research group has focused in their capability for reducing the toxic compounds generated in the smoking process when mixed with tobacco. By tuning the ...

    Immune functions are perturbed to a greater extent with smoking rather than moist snuff use

    TRAN Q.T.(1); ARIMILLI S.(2); JOHNSON E.(3); LIU Gang(1); PRASAD G.L.(1)

    Cigarette smoking is a major risk factor for lung cancer, chronic obstructive pulmonary disease, and cardiovascular disease (CVD). Existing epidemiological data suggest moist snuff consumption is generally associated with reduced health risks relative to ...

    Effect of the addition of SBA-15 in the pyrolysis of a reference tobacco under inert and oxidizing atmosphere

    CALABUIG E.; MARCILLA A.; BELTRÁN M.I.
    University of Alicante, San Vicente del Raspeig, Spain
    The composition of evolved products from slow pyrolysis under inert and oxidizing atmospheres of a reference tobacco 3R4F from the Reference Cigarette Program of the College of Agriculture of the University of Kentucky and a mixture of the reference ...

    Influence of the time of synthesis of SBA-15 on its effect as a catalyst reducing toxicant concentration in tobacco smoke

    JUÁREZ-SERRANO N.; MARCILLA A.; BELTRÁN M.I.
    University of Alicante, San Vicente del Raspeig, Spain
    In recent years, SBA-15 has been suggested as an additive for reduction of toxic compounds in tobacco smoke. The structure of this type of materials is strongly dependent on the synthesis conditions. The objective of the present work is to analyze the ...

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

    (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 ...

    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 ...
