The relation between respiratory symptoms and the range of tobacco product use among US adolescents/young adults is not yet clear. This cross-sectional analysis examines tobacco product use and respiratory symptoms in a nationally representative sample of 21,057 adolescents/young adults aged 12-24 years from Wave 4 (2016-17) of the Population Assessment of Tobacco and Health Study.
Lactate is a metabolite produced during anaerobic glycolysis for ATP resynthesis, which accumulates during hypoxia and muscle contraction. Tobacco smoking significantly increases blood lactate. Here we conducted a counter-balanced crossover study to examine whether this effect is associated with inhaling nicotine or burned carbon particles.
To determine the risk for oral cancer caused by simultaneous occurrence of more than one of the tested cytochrome P450 CYP1A1 MspI, glutathione S-transferase M1 null gnd Glutathione S-transferases T1 null gene polymorphisms.
To investigate the association between the intensity and cumulative dose of cigarette smoking and incidence risk of metabolic syndrome (MetS) in a longitudinal prospective study over 12 years of follow-up.
The present study used data from wave 4 of the Population Assessment of Tobacco and Health (PATH) study, a large, nationally representative U.S. study, to examine relationships among sociodemographic characteristics, internal and external factors, and tobacco use behaviors, with a focus on TGD individuals.
Repair index (RI) using DNA changes reveals the activity of carcinogenesis. Cigarette and waterpipe smoking are important contributors to oral cavity malignancy. The RI in cigarette and waterpipe smokers has not been compared so far. The aim of this study was to compare the RI in cigarette and waterpipe smokers using the human exfoliated buccal mucosa cells.
Nicotine increases reinforcing effects of cigarette smoking by upregulating glutamate and dopamine releases via stimulation of nicotinic acetylcholine receptors (nAChRs) in the dorsal striatum (CPu). The present study was conducted to evaluate whether non-nicotine substances in cigarette smoke potentiate nicotine-induced behaviors by increasing glutamate and dopamine concentrations in the CPu.
The intestinal microbiota is a crucial regulator of human health and disease because of its interactions with the immune system. Tobacco smoke also influences the human ecosystem with implications for disease development. This systematic review aims to analyze the available evidence, until June 2021, on the relationship between traditional and/or electronic cigarette smoking and intestinal microbiota in healthy human adults.
