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 …

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
… 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 for the …

Biomarker in Atemkondensat und Serum bei asbestbedingten Lungenfibrosen
… 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 tyrosine are …

Analysis of Endogenous Particles in Exhaled Air
… in the analysis of exhaled particles and exhaled breath condensate. In parallel to chemical analysis, the hypothesis that particles are formed during the reopening of closed airways was tested by measuring particle number concentrations in the air exhaled by healthy volunteers performing different …

Biomarkers of oxidative stress and inflammation in biological samples collected from recurrent airway obstruction (RAO)-affected horses and their controls
… 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 in …

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
… 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 the …

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 couple …

Sensitive microarray-based biomarker detection using photonic crystal enhanced fluorescence and label-free imaging
… biomarker detection in serum, saliva, urine, or breath condensate samples holds great promise for disease diagnostics and therapy monitoring because of its non-invasive nature. The microarray format, for its high-throughput and low analyte consumption characteristics, is particularly well suited …

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
… 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 the …

Exhalatkondensat bei Gesunden und thorakal bestrahlten Patienten
Die thorakale Strahlentherapie birgt stets das Risiko der Entstehung einer Pneumonitis, deren frühe Diagnose wichtig ist. Mit der Exhalat-Kondensat-Methode gelingt es, die alveoläre Oberfläche wenig invasiv und beliebig oft wiederholbar untersuchen zu können. Methodik, Variabilität der …

Versuch einer Standardisierung der Exhalatkondensation
Versuch einer Standardisierung der Exhalationskondensation Die Atemkondensatmessung ist eine ein nichtinvasives Verfahren zur Sammlung von Material aus den unteren Atemwegen, welches in den letzten Jahren immer mehr Beachtung gefunden hat. Mit dieser Methode können nicht flüchtige Subastanzen wie …
