Exhaled breath condensates and COPD.
BORRILL et al. [1] have recently provided a timely review of exhaled breath condensates (EBC) in chronic obstructive pulmonary disease. However, there are several issues that deserve comment. BORRILL et al. [1] argue that although it would be useful to use dilutional indicators for estimating the dilution of respiratory droplets from the airway lining fluid (ALF) by water vapour, none of these ...
متن کاملDiagnosis of lung cancer by the analysis of exhaled breath with a colorimetric sensor array.
BACKGROUND The pattern of volatile organic compounds (VOCs) in the exhaled breath of patients with lung cancer may be unique. New sensor systems that detect patterns of VOCs have been developed. One of these sensor systems, a colorimetric sensor array, has 36 spots composed of different chemically sensitive compounds impregnated on a disposable cartridge. The colours of these spots change based...
متن کاملExhaled breath analysis with a colorimetric sensor array for the identification and characterization of lung cancer.
INTRODUCTION The pattern of exhaled breath volatile organic compounds represents a metabolic biosignature with the potential to identify and characterize lung cancer. Breath biosignature-based classification of homogeneous subgroups of lung cancer may be more accurate than a global breath signature. Combining breath biosignatures with clinical risk factors may improve the accuracy of the signat...
متن کاملExhaled breath condensate biomarkers in COPD.
Biomarkers in chronic obstructive pulmonary disease may be useful in aiding diagnosis, defining specific phenotypes of disease, monitoring exacerbations and evaluating the effects of drugs. Exhaled breath condensate is a noninvasive means of sampling the airways, allowing biomarkers of airway inflammation and oxidative stress to be measured. In the present review, the use of exhaled breath cond...
متن کاملToward a hydrogen peroxide sensor for exhaled breath analysis
In this contribution a chip-integrated amperometric sensor for the detection of H2O2 in exhaled breath condensate (EBC) is reported. The electrode chip is characterized, and detection of H2O2 in an aqueous phase is shown by means of cyclic voltammetry (CV) and amperometry. Variation of conditions such as the composition of the supporting electrolyte largely influences the obtained electrochemic...
