    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...

    Currently, tobacco product submissions are organized differently across application types and often, across applicants, and are received in a format that is not amenable for reviewers to organize and easily find what they need. This “unstructured”...

    Comparison of the acetaldehyde, formaldehyde, and acrolein yields in cigars under different smoking regimens using a linear cigarette smoking machine

    YOUNG M.; CECIL T.L.; JOHNSON T.; FENG S.
    US Food and Drug Administration (FDA), Calverton, MD, USA
    Currently, there is very little information on the mainstream smoke yields of carbonyl compounds (e.g., formaldehyde, acetaldehyde, and acrolein) in cigar tobacco products. This study used a standard linear smoking machine and puffing protocols to...

    Cigars are among the broad variety of deemed tobacco products that have been less extensively studied and characterized than cigarettes. Small sheet-wrapped cigars, often called little cigars, are a subcategory of cigars that are similar to...

    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...

    In May 2016, the jurisdiction of the Federal Food Drug and Cosmetic Act was extended to include all tobacco products, including cigars. Because limited information exists on the chemistry of cigar filler and smoke, 60 brands of popular little cigars...

    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...

    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...
