Ciliated epithelium represents the first line of host defense against lung infection. Most alcoholics smoke and are at high risk for developing lung infections. We reported that cigarette smoke activates protein kinase C (PKC) and alcohol desensitizes ciliary beat frequency (CBF) to beta-agonists in bovine bronchial epithelial cells in vitro. The combined effect of smoke and alcohol exposure on...

Effects of tobacco smoke on hematologic derangements have received little attention. This study employed a mouse model of cigarette smoke exposure to explore the effects on bone marrow niche function. While lung cancer is the most widely studied consequence of tobacco smoke exposure, other malignancies, including leukemia, are associated with tobacco smoke exposure. Animals received cigarette s...

This study evaluated the hypothesis that smoke from harm reduction cigarettes impedes attachment and proliferation of H9 human embryonic stem cells (hESCs). Smoke from three harm reduction brands was compared with smoke from a conventional brand. Doses of smoke were measured in puff equivalents (PE) (1 PE = the amount of smoke in one puff that dissolves in 1 ml of medium). Cytotoxic doses were ...

several epidemiological studies have reported that passive smoking (ps) is a public health hazard and perhaps increases the risk of heart disease. this study evaluated the relationship between female coronary heart disease and ps among married women who described themselves as non-smokers in an area of south-east iran. using household exposure to tobacco smoke as an estimate of ps, a hospitalba...

BACKGROUND One of the requirements of the Osun State smoke-free legislation is to ensure smoke-free enclosed and partially enclosed workplaces. This survey was conducted to assess the knowledge and attitude of workers in indoor bars, beer parlors and discotheques to smoke-free legislation in general and the Osun State smoke-free law in particular. METHODS A convenience sampling of 36 hospital...

A novel and effective approach is proposed in this paper to detect smoke using transmission from image or video frame. Inspired by the airlightalbedo ambiguity model, we introduce the concept of transmission as a new essential feature of smoke, which is employed to detect the smoke and also determine its corresponding thickness distribution. First, we define an optical model for smoke based on ...

objective: infertility is an important social concern. environmental factors such as smoking and tobacco consumption can affect sperm and follicular function and infertility. smoke cessation reduces its complications and makes infertility treatment more effective which motivates and encourages infertile smokers to consider quitting. the aim of current study was to assess brief smoking cessation...

Cigarette smoke contains around 4000 chemical substances including free radicals and carcinogens, which are xenobiotic agents in the body, affecting the reproductive system. Purple sweet potatoes contain the color pigment anthocyanin. The purple color pigment (anthocyanin) in purple sweet potatoes is a beneficial antioxidant because it can react with free radicals that can cause damage in the b...
