Syrian golden and European hamsters were exposed to 14C-labelled cigarette smoke. The deposition of the 14C activity in the respiratory and digestive tracts was determined immediately after the exposure. From the results obtained it can be seen that the distribution of particulate matter between the upper and lower respiratory tract, as well as, between the respiratory and digestive tracts is related to the body weight of the experimental animals.

Objective: To compare the salivary profiles of smokers (e-cigarette smokers, e-cigarette and former conventional cigarette smokers, dual users, and conventional cigarette smokers) and non-smokers in adolescents, focusing on acidity level, flow rate, viscosity, as well as the quantity of Streptococcus mutans, Porphyromonas gingivalis, and Candida albicans.
Methods: This analytical observational study, with a cross-sectional design, involves collecting saliva samples from five groups through the draining method. Saliva viscosity was assessed visually, while saliva flow rate was monitored over a ten-minute period.
Background And Aims: Tobacco use among students is one of the most alarming problems throughout the world. This study was carried out to investigate the prevalence of cigarette and waterpipe smoking as well as their determinants among students in dormitories of Jahrom University of Medical Sciences.
Methods: This cross-sectional study was conducted on 293 students living in the dormitories of Jahrom University of Medical Sciences using random sampling method.

Background And Method: This study set out to identify the factors and combinations of factors associated with the individual's premature death, using data from the Finnish Longitudinal Study on Ageing Municipal Employees (FLAME) which involved 6,257 participants over a 29-year follow-up period. Exact dates of death were obtained from the Finnish population register. Premature death was defined as a death occurring earlier than the age- and sex-specific actuarial life expectancy indicated by life tables for 1981, as the baseline, with the threshold period of nine months.

Cigarette smoke extract (CSE)-induced airway mucus hypersecretion and inflammation are prominent features of chronic obstructive pulmonary disease (COPD). As a factor associated with inflammation regulation, T cell immunoglobulin and mucin domain-1 (TIM-1) is found to be involved in various inflammatory disorders such as asthma and COPD. In this study, the GEO database provides two human COPD gene expression datasets (GSE67472, n = 62) along with the relevant controls (n = 43) for differentially expressed gene (DEG) analyses.
