Assessment of a methodology for determination of H[2]O[2] concentration and pH in exhaled breath condensate in horses with and without lower airway inflammation
… hydrogen peroxide (H2O2) concentration and pH in exhaled breath condensate (EBC) is useful for detection and monitoring of diseases of the lower respiratory tract in humans, including asthma and chronic obstructive pulmonary disease. In contrast, limited information on the use of these parameters …

Biomarker in Atemkondensat und Serum bei asbestbedingten Lungenfibrosen
… was very successful. Measurements were taken in exhaled breath condensate and serum. In exhaled breath condensate there is a high dilution effect which has to be compensated by relation to the standardisation parameters. The sample volume of 1 ml was still sufficient. In serum proline and …

Auswirkung von körperlicher Belastung auf die Konzentration von 3-Nitrotyrosin im Atemkondensat
… functional pulmonary damages. The analysis of breath condensate is a new non-invasive method to examine processes in the air passages. The breath condensate contains non-gaseous compounds of exhaled breath, which reflects the composition of the bronchoalveolar extracellular lining fluid. The …

Analysis of Endogenous Particles in Exhaled Air
Exhaled air contains non-volatile particulate material from the respiratory tract. The precise location in which exhaled particles are formed is unknown, and details on their chemical content are scarce. The aim of this work was to chemically characterize and to study the mechanisms of formation of …

Biomarkers of oxidative stress and inflammation in biological samples collected from recurrent airway obstruction (RAO)-affected horses and their controls
… inflammatory and oxidative stress biomarkers in exhaled breath condensate (EBC), bronchoalveolar lavage fluid (BALF), red blood cells, white blood cells, and plasma; and cytokine expression in airway inflammatory cells and mucosal biopsies of RAO-affected horses and their controls. Sixteen horses …

Characterisation of exacerbations in non-CF Bronchiectasis to establish endpoints in measuring treatment efficacy
… by a visual analogue score are useful endpoints. Breathlessness is a reliable endpoint when measured using either a visual analogue score or modified Borg’s breathlessness score. Health related quality of life measured using the Euroqol questionnaire is a sensitive marker of change during an …

Health Assessment of Artisanal Metal Work: Injury Patterns, Aerosol Exposures, and Biomonitoring
… biological matrices: blood, urine, saliva, and exhaled breath condensate (EBC). Blood samples yielded the most consistent quantification, particularly for manganese and chromium, and correlated with personal air concentrations. Saliva and EBC also showed promise as non-invasive alternatives for …

Exhaled nitric oxide in asthmatic airway inflammation
Measuring the level of exhaled NO (eNO) in the breath is a new method to monitor airway inflammation in asthma and may have a role in the management of asthma. The hypotheses were that eNO will reflect the degree of inflammation in chronic asthma, and will indicate how anti- inflammatory therapy …

Nitric oxide in airway inflammation
Exhaled breath condensate (EBC) is a non-invasive method of investigating airway inflammation associated with nitric oxide (NO) and the metabolites nitrite/nitrates (NOx) in diseases such as chronic obstructive pulmonary disease (COPD), but some of the variables affecting the results are unknown. …

Detection of hydrogen peroxide and ethanol in exhaled breath using biosensors: Considerations in standardizing breath collection
Breath monitoring is a non-invasive, safe, and repeatable approach to determining the health status of humans and other mammals. Breath samples could be detected in two ways directly sensing exhaled breath (EB) or chilling the EB to obtaining the exhaled breath condensate (EBC). Each has its …

Analytical methods to investigate occupational exposure to toxic elements and their species
… the work in this thesis also evaluates exhaled breath condensate (EBC) for its potential as a new biological matrix for biological monitoring of chromium and RCS. The analytical technique used for arsenic speciation, chromium speciation and single particle analysis of RCS was inductively …

N[Epsilon]-(Carboxymethyl)Lysin und 3-Nitrotyrosin im Atemkondensat von Patienten mit chronischem Nierenversagen
Exhaled breath condensate (EBC) is the exhaled water steam with dissolved substances, which are set free from the airway lining fluid in small droplets. EBC can be collected and analysed by cooling down the exhaled air and collecting the condensate. Oxidative stress is the imbalance of increased …

Oxidative stress and metal homeostasis at the air-lung interface in Chronic Obstructive Pulmonary Disease
… and oxidative damage marker concentrations in exhaled breath condensate and induced sputum. Whilst these samples are easier to obtain than bronchoscopy-based lavage, there remains contention concerning how well they reflect the distal airway lining fluids and hence the actual disease state. In …
