The so-called reactive oxygen species (ROS) are defined as oxygen-containing species that
are more reactive than O 2 itself, which include hydrogen peroxide and superoxide …

Oxidative stress and DNA damage have been proposed as mechanisms linking pesticide
exposure to health effects such as cancer and neurological diseases. A study of pesticide …

Chronic inflammation and oxidative stress are important features in the pathogenesis of
COPD. The increased oxidative stress in patients with COPD is the result of an increased …

Study objectives The aim of this study was to characterize the elemental composition of
exhaled breath condensate (EBC) in order to identify new biomarkers of exposure and …

Chronic obstructive pulmonary disease (COPD) is associated with a high incidence of
morbidity and mortality. Cigarette smoke-induced oxidative stress is intimately associated …

Despite the attractiveness of breath analysis as a non-invasive means to retrieve relevant
metabolic information, its introduction into routine clinical practice remains a challenge …
