    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 for...

    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...

    The development of low TSNA air-cured tobaccos. I. Effects of tobacco genotype and fertilization on the formation of TSNA

    WAHLBERG I.; LONG R.C.; BRANDT P.; WIERNIK A.
    Swedish Match, Research & Analysis, Stockholm, Sweden
    A project having the objective to evaluate tobaccos suitable for smokeless products was initiated in 1989. In the course of this project, a broad range of genotypes was grown under a regimen of heavy nitrogen fertilization (250 lbs N/A) near...

    The development of low TSNA air-cured tobaccos. II. Effects of curing conditions and post-curing drying on TSNA formation

    LONG R.C.; WAHLBERG I.; BRANDT P.; WIERNIK A.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    As a part of the project to produce dark air-cured tobaccos with low TSNAs and other acceptable characteristics, studies were conducted to evaluate the effect of varying curing conditions. Very low levels of TSNAs were observed when tobaccos were...
