In Vitro Inhibition of Human Sperm Creatine Kinase by Nicotine, Cotinine and Cadmium, as a Mechanism in Smoker Men Infertility
Background Nicotine, cotinine and cadmium are harmful components of cigarettes that have an effect on human reproductive function. Although the effects of cigarette smoke on male reproductive function is characterized in several articles its mechanism of action is still unknown. In the present study, we investigate the effect of nicotine, cotinine and cadmium on human sperm creatine kinase acti...
متن کاملEffects of nicotine patch or nasal spray on nicotine and cotinine concentrations in pregnant smokers.
OBJECTIVE To examine the short-term effects of the nicotine patch or nasal spray on measures of nicotine exposure, withdrawal symptoms, and on maternal and fetal heart rates in pregnant smokers. METHODS We measured nicotine/cotinine concentrations and maternal and fetal heart rates during an 8-h monitoring session while smoking and again after 4 days of nicotine patch (15 mg/16 h), nasal spra...
متن کاملEffects of basic fibroblast growth factor on density and morphology of fibroblasts grown on root surfaces with or without conditioning with tetracycline or EDTA.
A study was conducted to evaluate in vitro the effect of root surface conditioning with basic fibroblast growth factor (b-FGF) on morphology and proliferation of fibroblasts. Three experimental groups were used: non-treated, and treated with 50 microg or 125 microg b-FGF/ml. The dentin samples in each group were divided into subgroups according to the chemical treatment received before applicat...
متن کاملthe in-vitro effects of nicotine, cotinine and leptin on sperm parameters analyzed by casa system
backgrand: cotinine (cot) is a major degradation product of nicotine (nic). the participation of leptin in female reproduction is well-established, but any role in male reproductive function is at the best tenuous. objective: the aim of this study was to evaluate the in-vitro effects of nicotine, cotinine and leptin on sperm parameters in normal semen of non-smokers fertile men. materials and m...

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
