The purpose of this period prevalence study is to compare the prevalence of cardiovascular disease (CVD) in current/former established smokeless tobacco (SLT) users (ever SLT users who have used the product fairly regularly) to those who were: 1) never established cigarette smokers and SLT users, and 2) current/former established exclusive cigarette smokers (have smoked at least a 100 or more cigarettes in lifetime) only, adjusting for known risk factors for CVD.
aPDT adjunctive to MD improved periodontal parameters i.e., plaque index, pocket depth, and crestal bone loss along with metabolic marker RANK-L in water pipe smokers compared to non piped smokers.
N-Nitrosonornicotine (NNN) is a human carcinogen present in cigarette smoke and smokeless tobacco. Urinary NNN is usually measured in order to assess the exposure to this toxicant for tobacco users.
This study aimed to assess the effects of BPA maternal exposure on CYP450s expression in fetal brain. Sprague-Dawley dams were exposed to BPA concentrations of 0, 0.5, 5, and 50 mg/L in drinking water, individually, and with nicotine. Fetal brains were isolated at gestational days GD14 and GD19, and protein expression was assessed by Western blotting. Results showed a BPA-induced significant decrease in CYP1B1 expression levels at GD14 (p = 0.001), and CYP19A1 (aromatase) expression at both mid- and late-stage development (p < 0.001). In addition, nicotine individually decreased expression levels of all examined protein targets, significantly for CYP1B1 (p < 0.001), CYP19A1 (p = 0.010), AhRR (p = 0.042), and ARNT (p < 0.001), compared to control. When combined with BPA, nicotine suppressive effects were attenuated at both GD14 and GD19.
Smoking triggers environmental changes in the oral cavity and increases the risk of mucosal infections caused by Candida albicans such as oral candidiasis. While cigarette smoke has a significant impact on C. albicans, how e-cigarettes affect this oral pathogen is less clear.
Tobacco use is a well-established risk factor for multiple adverse oral conditions. Few nationally representative oral health data sets encompass the current diversity of tobacco and nicotine products.
Aromatic amines are a class of carcinogenic compounds in tobacco smoke that are listed on the FDA list of harmful and potentially harmful constituents (HPHCs).
The goal of this paper is to investigate the influence of oral dipping of Tombak Smokeless Tobacco (SLT) on prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio(INR) values, and platelet counts (PLTs), in Sudanese Tombak users.
