Nasal eosinophilia: an indicator of eosinophilic inflammation in asthma
(WILEY-BLACKWELL, 2010)
Background It is noteworthy that there is a clear clinical, epidemiological and pathophysiological association between upper and lower airway inflammation in rhinitis and asthma. Objective The aim of this study was to ...
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 ...
Irrigação intranasal: avaliação dos efeitos do uso de soluções hidroeletrolíticas na mucosa de ratos
(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2003-08-01)
Nasal irrigation is an important adjuvant therapy for nasosinusis diseases. Many hydroelectrolytic solutions have been used for it, but studies are lacking to analyze the histological reactions they may cause to the nasal ...
CR3 (CD11b/CD18) activation of nasal neutrophils: a measure of upper airway endotoxin exposure
(TAYLOR & FRANCIS LTD, 2009)
Inhaled endotoxin (lipopolysaccharide, LPS) initiates an inflammatory response and leads to the expression of CR3 (CD11b/CD18) receptors on polymorphonuclear leukocytes (PMNs). We determined if PMN activation in nasal ...
Subchronic effects of nasally instilled diesel exhaust particulates on the nasal and airway epithelia in mice
(TAYLOR & FRANCIS INC, 2010)
Diesel exhaust is the major source of ultrafine particles released during traffic-related pollution. Subjects with chronic respiratory diseases are at greater risk for exacerbations during exposure to air pollution. This ...
