Abstract excerpt

RATIONALE: Asthma is often characterised by inflammation, damage and dysfunction of the small airways, but no standardised biomarkers are available. OBJECTIVES: Using a novel approach-particles in exhaled air (PExA)-we sought to (a) sample and analyse abundant protein biomarkers: surfactant protein A (SPA) and albumin in adult asthmatic and healthy patients and (b) relate protein concentrations with physiological...
