The intake of maqui (Aristotelia chilensis) berry extract normalizes H2O2 and IL-6 concentrations in exhaled breath condensate from healthy smokers - an explorative study
(BioMed Central, 2015)
Background: Respiratory diseases are associated with pulmonary oxidative stress and inflammatory processes.
Though studies in animal models suggest that dietary polyphenols improve lung injury, no intervention studies
were ...
Increase of pro-oxidants with no evidence of lipid peroxidation in exhaled breath condensate after a 10-km race in non-athletes
(Springer, 2014)
It is a well-established fact that exercise increases pro-oxidants and favors oxidative stress; however, this phenomenon has been poorly studied in human lungs. Pro-oxidative generation (H(2)O(2), NO(2) (-)), lipid ...
pH in exhaled breath condensate and nasal lavage as a biomarker of air pollution-related inflammation in street traffic-controllers and office-workers
(Faculdade de Medicina / USP, 2013-12-01)
OBJECTIVE: To utilize low-cost and simple methods to assess airway and lung inflammation biomarkers related to air pollution. METHODS: A total of 87 male, non-smoking, healthy subjects working as street traffic-controllers ...
Update on the Mechanisms of Pulmonary Inflammation and Oxidative Imbalance Induced by Exercise
(2016)
The mechanisms involved in the generation of oxidative damage and lung inflammation induced by physical exercise are described. Changes in lung function induced by exercise involve cooling of the airways, fluid evaporation ...
Comparison of Ambient and Atmospheric Pressure Ion Sources for Cystic Fibrosis Exhaled Breath Condensate Ion Mobility-Mass Spectrometry Metabolomics
(Elsevier Science Inc, 2017-08)
Cystic fibrosis (CF) is an autosomal recessive disorder caused by mutations in the gene that encodes the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The vast majority of the mortality is due to ...
Beta-Lactam Antibiotics Can Be Measured in the Exhaled Breath Condensate in Mechanically Ventilated Patients: a Pilot Study
(2023)
Different techniques have been proposed to measure antibiotic levels within the lung parenchyma; however, their use is limited because they are invasive and associated with adverse effects. We explore whether beta-lactam ...
A novel non-invasive tool for disease surveillance of large free-ranging whales and its relevance to conservation programs
(Animal Conservation, 2010)
The numbers of potentially pathogenic microorganisms that have been isolated from stranded cetaceans in the last three decades underscore the urgent need for methods of detection of microorganisms that might cause significant ...
