    Oxidation dynamics of e-liquids in electronic nicotine delivery systems with atomisers of various types

    TROFIMOV A.V.; MENSHOV V.A.; YABLONSKAYA O.I.
    Emanuel Institute of Biochemical Physics, Russian Academy of Sciences, Moscow, Russian Federation
    The processes of the thermal oxidative destruction of e-liquid components play a key role in the appearance of undesirable products in aerosols generated by electronic nicotine delivery systems (ENDS). The objective of the present studies is to obtain ...

    Between vapour and smoke? Prooxidant activity of electronic cigarette emissions

    TROFIMOV A.V.; MENSHOV V.A.
    Emanuel Institute of Biochemical Physics, Russian Academy of Sciences, Moscow, Russian Federation
    Electronic cigarettes (e-cigs) are considered among the most promising tools designed for the reduction of a potential harm derived from smoking. Nevertheless, debates exist over the scientific evidence for claims that e-cigs have no health-related ...

    Cigarette smoke as a source of exogenous and endogenous antioxidants in smokers: novel findings

    TROFIMOV A.V.; MENSHOV V.V.; YABLONSKAYA O.I.
    Emanuel Institute of Biochemical Physics, RAS, Moscow, Russian Federation
    Cellular oxidative stress, derived from imbalance between the production of reactive oxygen species and the efficacy of the antioxidant defence, can be a direct and/or indirect consequence of cigarette smoking. Pro-oxidant properties of cigarette smoke ...

    Influence of gaseous phase components from mainstream cigarette smoke on the propensity of smoke particulate matter to generate hydrogen peroxide

    TROFIMOV A.V.; MENSHOV V.A.
    Emanuel Institute of Biochemical Physics, Russian Academy of Sciences, Moscow, Russian Federation
    Generation of hydrogen peroxide (H 2 O 2) by chemicals in mainstream cigarette smoke is of prime interest for the estimation of the pro-oxidant activity of the smoke. Since most of phenolic compounds (potential H 2 O 2 precursors) reside in the ...

    Chemiluminescence approach to monitor efficiency of cigarette filters

    TROFIMOV A.V.; MENSHOV V.A.
    Emanuel Institute of Biochemical Physics, Russian Academy of Sciences, Moscow, Russian Federation
    It is known that fresh cigarette smoke is at an excited state and this is reflected by the light emission or chemiluminescence. Chemiluminescence of the cigarette smoke can be measured from the mainstream smoke emitted from cigarette filters. In this work ...

    Redox processes in a smoker's organism: Between the imbalance and the stress

    TROFIMOV A.V.; MENSHOV V.A.
    Emanuel Institute of Biochemical Physics, Russian Academy of Sciences, Moscow, Russian Federation
    Estimating a smoker's health may utilise approaches based on the role of oxidative stress in pathogenic developments. In this context, oxidative stress is often considered as an imbalance in redox processes. Nevertheless, our analysis of the ...

    Smoke-derived chemiluminescence as phenomenon and experimental tool

    TROFIMOV A.V.; FEDOROVA G.F.; MENSHOV V.A.; TSAPLEV Yu.B.; VASIL’EV R.F.
    Emanuel Institute of Biochemical Physics, Russian Academy of Sciences, Moscow, Russian Federation
    Chemiluminescence emission can be detected from cigarette smoke. This is thought to link to smoke free radicals, many of which are reactive oxygen and nitrogen species of excited states. Smoke-derived chemiluminescence was first observed in the mid-1970s, ...
