Nitric Oxide in the Exhaled Breath Condensate of Healthy Volunteers Collected With a Reusable Device
(EDICIONES DOYMA S ABARCELONA, 2012)
Background: The analysis of exhaled breath condensate (EBC) is a non-invasive technique that enables the determination of several volatile and nonvolatile substances produced in the respiratory tract, whose measurement may ...
Inflammatory mediators in exhaled breath condensate of healthy donors and exacerbated COPD patients
(Elsevier, 2012-06)
Samples of exhaled breath condensate (EBC) provide a convenient and non-invasive method to study inflammation in lung diseases. The aim of the present study was to evaluate and compare the inflammatory protein mediator ...
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 ...
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 ...
Feasibility of Early Detection of Cystic Fibrosis Acute Pulmonary Exacerbations by Exhaled Breath Condensate Metabolomics: A Pilot Study
(American Chemical Society, 2017-02)
Progressive lung function decline and, ultimately, respiratory failure are the most common cause of death in patients with cystic fibrosis (CF). This decline is punctuated by acute pulmonary exacerbations (APEs), and in ...
Moderate altitude but not additional endurance training increases markers of oxidative stress in exhaled breath condensate
(CIENCIAS, 2009)
Oxidative stress occurs at altitude, and physical exertion might enhance this stress. In the present study, we investigated the combined effects of exercise and moderate altitude on redox balance in ten endurance exercising ...
Moderate altitude but not additional endurance training increases markers of oxidative stress in exhaled breath condensate
(2009)
Oxidative stress occurs at altitude, and physical exertion might enhance this stress. In the present study, we investigated the combined effects of exercise and moderate altitude on redox balance in ten endurance exercising ...
Exhaled breath condensate collection for nitrite dosage: a safe and low cost adaptation
(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2010)
PURPOSE: Standardization of a simple and low cost technique of exhaled breath condensate (EBC) collection to measure nitrite. METHODS: Two devices were mounted in polystyrene boxes filled either with crushed ice/salt ...
Lung oxidative stress as related to exercise and altitude. Lipid peroxidation evidence in exhaled breath condensate: a possible predictor of acute mountain sickness
(CIENCIAS, 2005)
Lung oxidative stress (OS) was explored in resting and in exercising subjects exposed to moderate and high altitude. Exhaled breath condensate (EBC) was collected under field conditions in male high-competition mountain ...
Nitrite exhaled breath condensate study in patients undergoing cardiopulmonary bypass cardiac surgery
(Sociedade Brasileira de Cirurgia Cardiovascular, 2011)
BACKGROUND: There is a relative lack of studies on postoperative changes in nitrite (NO2 - ) concentrations, a marker of injury, following cardiac surgery. In this context, investigations on how exhaled NO concentrations ...
