For years it has been postulated that the cigarette smoker adversely affects the nonsmoker by contaminating the indoor atmosphere (2,3). Recently, the U.S. Surgeon General, J. L. Steinfeld, focused public attention on the question when he requested a ban on smoking in closed public spaces (4). The average person spends the great majority of his time, probably 80 to 90 percent, indoors (5);thus,...

BACKGROUND The prevalence of home smoking bans in the United States has increased overtime, but educational disparities have persisted. Little research has explored potential associations between tobacco control policies and disparities by socioeconomic status in home smoking bans. We examined educational disparities in home smoking bans in the United States from 1995 to 2007 and investigated t...

The objective of the present study was to assess the ascorbic acid (AA) levels in seminal plasma of the fertile and infertile men and to investigate its relationship with sperm count, motility and normal morphology. Semen samples were provided by fertile [smoker (n = 25), nonsmoker (n = 21)] and infertile men [smoker (n = 23), nonsmoker (n = 32)]. A simplified method of reverse phase high perfo...

Background: The prevalence of asthma varies among different regions based on the presence risk factors. Second-hand smoking is one factors that leads to an increased prevalence, exacerbation, and poor control asthma. Thereby, this study aimed investigate children impact second-hand patients. Methodology: This cross-sectional included parents in Saudi Arabia. It was conducted during period from...

We examined the relationship between maternal smoking during pregnancy and serum lipid, lipoprotein and apolipoprotein levels in newborns. Serum concentrations of total cholesterol, triglyceride, high density lipoprotein cholesterol, low density lipoprotein cholesterol, apolipoprotein A-1, apolipoprotein B and lipoprotein (a) were assessed in blood samples from 38 mothers who were smokers and t...

Exposure to ozone causes symptoms, changes in lung function, and airway inflammation. We studied whether individuals who differ in lung-function responsiveness to ozone, or in smoking status, also differ in susceptibility to airway inflammation. Healthy subjects were selected on the basis of responsiveness to a classifying exposure to 0.22 ppm ozone for 4 h with exercise (responders, with a dec...

BACKGROUND/AIM This study determined the effects of cotinine concentrations in follicular fluid (FF) and seminal plasma (SP) on the pregnancy outcome of couples using assisted reproductive techniques (ARTs). MATERIALS AND METHODS This study was conducted as a case-control study. A total of 217 couples were included in the study. Among these couples, there were nonsmokers (66 women and 40 men)...

Regular tobacco use in the enclosed environment of a car raises concerns about longer-term contamination of a car's microenvironment with residual secondhand smoke pollutants. This study (a) developed and compared methods to measure residual contamination of cars with secondhand smoke, (b) examined whether cars of smokers and nonsmokers were contaminated by secondhand smoke, and (c) how smoking...
