The upregulation of nitric oxide (NO) by inflammatory cytokines and mediators in central and
peripheral airway sites can be monitored easily in exhaled air. It is now possible to estimate …

The effects of nitric oxide in biological systems depend on its steady-state concentration and
where it is being produced. The organ where nitric oxide is produced is relevant, and within …

Breath tests cover the fraction of nitric oxide in expired gas (F ENO), volatile organic
compounds (VOCs), variables in exhaled breath condensate (EBC) and other …

Nitric oxide (NO) is produced by a family of isoenzymes, nitric oxide synthases (NOSs),
which all utilize l-arginine as substrate. The production of NO in the lung and airways can …

The contribution of the alveolar compartment to exhaled nitric oxide (alveolar nitric oxide or
CA NO) can be calculated as a surrogate of distal inflammation. This value should be …

Air pollution contributes substantially to the development of chronic obstructive pulmonary
disease (COPD). To date, the effect of air pollution on oxygen saturation (SpO 2) during …

There is still an unexplored potential for exhaled nitric oxide (NO) in many clinical
applications. This study presents an overview of the currently available methods for …

Asthma is a chronic inflammatory disease of the lungs, characterized by airway
hyperresponsiveness. Chronic repetitive bouts of acute inflammation lead to airway wall …

High levels of exhaled nitric oxide (NO) predict favourable response to inhaled
corticosteroids in asthma, but the ability of exhaled NO or inflammatory markers in exhaled …

The extended exhaled nitric oxide (eNO) parameters, including peripheral or alveolar eNO,
are investigational biomarkers in COPD. In this study, the hypothesis was tested that …
