in this paper, we explore a nonlinear mathematical model to study the spread of asthma due to inhaled pollutants from industry as well as tobacco smoke from smokers in a variable size population. the model is analyzed using stability theory of differential equations and computer simulation. it is shown that with an increase in the level of air pollutants concentration, the asthmatic (diseased) ...
Background: It is well documented that cigarette smoking has negative impacts on body health, as well as social health, economy, culture, etc. Nowadays, there is a large body of evidence that smoking is the cause of numerous life-threatening diseases like cardiovascular and pulmonary diseases along with different kinds of cancer. The aim of this study was to compare the physical fitness of smok...
Background & Aim: Hexokinase and pyruvate kinase are two regulatory enzymes of glycolytic pathway in erythrocytes. Increasing evidence suggests that cigarette smoking which produces free radicals and oxidative stress can cause damage to body macromolecules such as proteins and enzymes. The aim of the present study was to investigate the susceptibility of key enzymes of erythrocytes glycolyt...
Background and Objective: Evaluation of neurocognitive mechanism involved in smoking can be helpful in the treatment of this dependence .The aim of this study was to compare the cognitive executive functions in frontal lobe of brain in male smokers and non-smokers. Materiasl and Methods: The method of research was causative-comparitive. In this regard, 40 male smokers and 40 male non-smokers...
Abstract Background and objectives: Smokers are exposed to significant quantities of ROS (Reactive Oxygen Species) and The Level of Nitric Oxide (NO), the primary vasodilator produced by endothelial cells, is changed by cigarette smoking. Cigarette smoking is associated with impaired endothelium-dependent vasodilatation and cardiovascular disease (CVD). The aim of this study is to determine the...
The purpose of this study was to examine the relationship between smoking and cardiopulmonary function, effect habit on exercise tolerance after discharge from hospital, focusing CPX test data patients hospitalized for acute myocardial infarction, at 6 months discharge. A total 123 male infarction April 2014 December 2020 were included. Laboratory compared smokers non-smokers. smokers, ex-smoke...
Background: Hypoxemia is a frequent complication after general anesthesia. It usually takes longer to recover in individuals with respiratory problems. Bakers may suffer from respiratory problems such as asthma. The objective of this study was to compare the occurrence of hypoxemia and duration of supplemental oxygen administration during recovery from general anesthesia in bakers and smokers. ...
Background: E-cigarettes are steadily gaining popularity in Korea. However, the characteristics of e-cigarette smokers, especially nicotine dependence and stress susceptibility, have not been evaluated comparison to those nonsmokers or combustible cigarette smokers Korea. Methods: In this study, 28,059 participants from Korea National Health Nutrition Examination Survey (2013-2017) were classif...
Background and purpose: Smoking increases the incidence and severity of periodontal disease. Elevation in the level of salivary soluble CD44 is considered as a diagnostic marker in some smoking-induced disorders such as periodontal disease. This study evaluated the salivary soluble CD44 level in smokers and non-smokers with and without moderate chronic periodontitis, before and one month after ...
introduction: to assess the salivary composition of proteins and minerals in smokers compared with non-smokers. materials and methods: in this study we compared the total protein and ca, na, k, mg, pb of whole saliva in two groups of men (28 smokers and 31nonsmokers) aged between 29-41years. results: fifty-nine participants were evaluated. the mean age was 33.14±5.32 years among smokers and...
