    Leaf chlorophyll content (LCC) is an important physiological parameter in the process of plant growth. Thus monitoring LCC can be used to detect and study plant mutations, pressure, and nutritional status. Wu et al. found that crop LCC had a linear...

    Review of current methodologies in evaluating abuse liability of nicotine and tobacco products in the U.S. regulatory environment

    EVANS S.(1); KONG M.C.(2); CAMPBELL L.(2); SHERWOOD N.(3); PRASAD K.(4)

    Traditional definitions of abuse and misuse do not apply to a consumer product such as tobacco that consumers essentially use ‘as intended’. In contrast to pharmaceutical products, a guidance for abuse liability testing of nicotine and tobacco...

    Examining the impact of very low nicotine content (VLNC) on cigarette use patterns – a review of current evidence and suggestions for further research

    Neil Sherwood Consulting, Nyon, Switzerland
    A number of scientists and regulatory bodies have called for a reduction in the nicotine content of cigarettes to a minimally addictive level in the expectation that there will be a subsequent increase in the number of smokers who quit and a...

    In the tobacco space, consumer-reported outcome measures (CROM) are essential for understanding motivations, subjective effects, and behavior. Such measures have become particularly important with the advent of candidate modified risk tobacco...

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

    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...

    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...

    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...
