    Potential of molecular marker analysis for assessment of genetic diversity in tobacco varieties

    ROSSI L.; BINDLER G.; PIJNENBURG H.; GADANI F.
    Philip Morris Europe, R&D, Neuchatel, Switzerland.
    The objective of the study was to investigate the genetic diversity of tobacco varieties by developing polymerase chain reaction (PCR)-based procedures that can detect DNA polymorphisms in tobacco. An effective DNA extraction method is required in order ...

    The application of polymerase chain reaction (PCR) technology to the detection, identification and quantification of genetically modified organisms (GMOs): current approaches

    GADANI F.; BINDLER G.; PIJNENBURG H.; ROSSI L.; ZUBER J.
    Philip Morris Europe, R&D, Neuchâtel, Switzerland.
    Analytical methods based on the polymerase chain reaction (PCR) technology are increasingly used for the detection of deoxyribonucleic acid (DNA) sequences associated with genetically modified organisms (GMOs). Prerequisites for GMO detection are a ...

    The effect of ingredients added to tobacco in a commercial Marlboro Lights cigarette on FTC nicotine yield, "smoke pH', and Cambridge filter trapping efficiency

    ELLIS C.; COX R.; CALLICUTT C.; LAFFOON S.; PODRAZA K.; SEEMAN J.; KINSER R.; FARTHING D.; HSU F.
    Philip Morris USA, Research Center, Richmond, VA, USA
    The objectives of this study were to determine the effect of added ammonia compounds and other ingredients, in levels utilized in a commercial cigarette, on: (1) FTC nicotine yield; (2) "smoke pH"; and (3) Cambridge filter trapping efficiency ...

    The oxidation of nicotine with sodium hypochlorite. Identification of some of the products formed, and a rationalization of the pathways by which they arose

    PAINE J.B. III
    Philip Morris USA, Research Center, Richmond, VA, USA
    The oxidation of nicotine with sodium hypochlorite was studied. Autoanalyzer-monitored reactions showed rapid consumption of about 8 molar equivalent of oxidant. Further oxidation was slow, incomplete, and pH-dependent. Simultaneous monitoring of pH ...

    Modeling nicotine intake in smokers and snuff users using biological fluid nicotine metabolites

    BOSWELL C.; CURVALL M.; ELSWICK R.K.; LEYDEN D.
    Philip Morris USA, Research Center, Richmond, VA, USA
    While urinary cotinine is the nicotine metabolite most commonly utilized to quantify nicotine intake, many additional nicotine metabolites have been identified and quantified in urine samples. Data from two studies involving smokers and snuff users are ...

    Experimental investigation of formation of aromatic hydrocarbon from pyrolysis of cellulosic materials

    HAJALIGOL M.R.; WAYMACK B.; KELLOGG D.
    Philip Morris USA, Research Center, Richmond, VA, USA
    The major chemical pathway to produce aromatic hydrocarbons in the pyrolysis followed by flaming combustion of biomass is high temperature secondary reactions of the primary pyrolysis products. The second and less explored route that is more pertinent to ...
