Oxidative stress can contribute to the development of diseases, and may originate from
exposures to toxicants commonly found in air pollution and cigarette smoke such as …

Objective: To evaluate the effect of cigarette smoking on oxidative and nitrosative stress, we
assessed urinary levels of 8-hydroxy-2′-deoxyguanosine (8-OHdG), isoprostane 15-F2t …

Cigarette smoking predisposes to the development of multiple diseases involving oxidative
damage. We measured a range of oxidative damage biomarkers to understand which differ …

Waterpipe (aka hookah) tobacco smokers are exposed to toxicants that can lead to oxidative
DNA and RNA damage, a precursor to chronic disease formation. This study assessed …

Introduction Cross-sectional studies have consistently shown an association between
current smoking and oxidative stress biomarkers. However, no longitudinal studies have …

Chronic obstructive pulmonary disease (COPD) is a disease characterized by chronic
inflammation and irreversible airway obstruction. Cigarette smoking is the predominant risk …

Background: The objective of this study was to obtain baseline data on biomarkers of
exposure (BoE) and biomarkers of potential harm (BoPH) in smokers, former smokers and …

Background: While cigarette smoking is the leading cause of lung cancer, the majority of
smokers do not develop the disease over their lifetime. The inter-individual differences in …

7, 8-Dihydro-8-oxo-2′-deoxyguanosine (8-oxo-dGuo) is a useful biomarker of oxidative
stress. However, its analysis can be challenging because 8-oxo-dGuo must be quantified in …

In a previous study, evidence was provided that indoor secondhand tobacco smoke (SHS)
air pollution remains high in Lisbon restaurants where smoking is allowed, regardless of the …
