background: cigarette smoking has been linked with the suppression of immune responses and increased susceptibility to numerous infections in humans. tetanus is also a major public health problem in many countries. the aim of the present study was to evaluate the serum levels of anti-tetanus toxin antibodies in c igarette smoking and healthy non-smoking people .   materials and methods: a total...

We consider the Yamabe flow of a conformally Euclidean manifold for which the conformal factor’s reciprocal is a quadratic function of the Cartesian coordinates at each instant in time. This leads to a class of explicit solutions having no continuous symmetries (no Killing fields) but which converge in time to the cigar soliton (in two-dimensions, where the Ricci and Yamabe flows coincide) or i...

BACKGROUND We aimed to investigate the immediate respiratory effects of cigar smoking(CS), among young smokers with and without mild asthma. MATERIALS AND METHODS Forty-seven young smokers (18-31years old, 29 males, average pack-years = 3.6 ± 2.8) were enrolled. Twenty-two were mild asthmatics(MA-subgroup) and the remaining 25 were otherwise healthy smokers(HS-subgroup). Exhaled carbon monoxi...

We provide a unified investigation of normal modes and sound propagation at zero temperature in Bose condensed gases confined in highly asymmetric harmonic traps and interacting with repulsive forces. By using hydrodynamic theory for superfluids we obtain explicit analytic results for the dispersion law of the low energy discretized modes for both cigar and disk shaped geometries, including the...

Abstract Background Polytobacco product use is increasingly popular, but little known about the prevalence, trend, and factors of such particularly in non-western countries. Method A representative sample 1139 current cigarette smokers aged 15+ (84.1% male) were telephone interviewed Tobacco Control Policy-related Surveys 2015–2017. Information collected included poly-tobacco (PTU), smoking soc...

STUDY OBJECTIVE To study the effect of long-term smoking on all-cause and cause-specific mortality, and to estimate the effects of cigarette and cigar or pipe smoking on life expectancy. DESIGN A long-term prospective cohort study. SETTING Zutphen, The Netherlands. PARTICIPANTS 1373 men from the Zutphen Study, born between 1900 and 1920 and studied between 1960 and 2000. MEASUREMENTS Ha...
