The purpose of this study is to demonstrate in patients with generalized chronic periodontitis that switching from cigarette smoking to using IQOS improves the response to periodontal ther...
It is well established in the scientific literature that people with schizophrenia smoke tobacco cigarettes at rates up to three times that of the general population, relapse more frequent...
The purpose of this study is to measure plasma nicotine uptake parameters, physiological measures, and subjective effect measures in smokers during and following a single ad libitum use of...
The purpose of this study is to assess the effects of electronic cigarettes-nicotine and electronic cigarette-nicotine free on endothelial function as compared to traditional cigarettes. ...
In this one-year pilot study of 30 non-treatment seeking young adult e-cigarette/cigarette dual users (15 males/15 females), we will use smartphone-based ecological momentary assessment (E...
Research indicates that electronic cigarette (e-cigarette) use (vaping) among adolescents is associated with the initiation and progression of combustible cigarette smoking. The reasons for this assoc...
Susceptibility to cigarette smoking has been used since the mid-1990s as a measure to identify youth at risk of cigarette initiation. However, it is unclear how well this measure predicts future smoki...
There is limited evidence on how cigarette smokers use electronic cigarettes (ECIGs) for smoking cessation and reduction. This study used concept mapping, a participatory mixed-methods research approa...
Understanding vaping patterns of electronic cigarette (EC) use is important to understand the real-life exposure to EC vapor. Long term information on vaping topography in relation to tobacco cigarett...
Sugars are major constituents and additives in traditional tobacco products, but little is known about their content or related toxins (formaldehyde, acetaldehyde, and acrolein) in electronic cigarett...
Electronic devices that are designed to provide NICOTINE in the form of an inhaled aerosol. They typically are made in the shape of CIGARETTES in order to simulate the experience of CIGARETTE SMOKING.
Electronic devices that increase the magnitude of a signal's power level or current.
A cytochrome P-450 monooxygenase that can be induced by polycyclic aromatic xenobiotics in the liver of human and several animal species. This enzyme is of significant clinical interest due to the large number of drug interactions associated with its induction and its metabolism of THEOPHYLLINE. Caffeine is considered to be a model substrate for this enzyme. CYP1A2 activity can also be increased by environmental factors such as cigarette smoking, charbroiled meat, cruciferous vegetables, and a number of drugs including phenytoin, phenobarbital, and omeprazole.
Cytoplasmic proteins that bind certain aryl hydrocarbons, translocate to the nucleus, and activate transcription of particular DNA segments. AH receptors are identified by their high-affinity binding to several carcinogenic or teratogenic environmental chemicals including polycyclic aromatic hydrocarbons found in cigarette smoke and smog, heterocyclic amines found in cooked foods, and halogenated hydrocarbons including dioxins and polychlorinated biphenyls. No endogenous ligand has been identified, but an unknown natural messenger with a role in cell differentiation and development is suspected.
Discarded electronic devices containing valuable and sometimes hazardous materials such as LEAD, NICKEL, CADMIUM, and MERCURY. (from http://www.epa.gov/osw/conserve/materials/ecycling/faq.htm#impact accessed 4/25/2010)
