INTRODUCTION Eosinophil cationic protein (ECP) has been widely investigated as a potential biomarker of airway inflammation. METHOD A systematic review was performed using Medline with key terms eosinophil cationic protein and asthma, limiting the search to titles or abstracts. Out of 688 potential papers found, abstracts were reviewed based on the(More)
BACKGROUND AND PURPOSE Depression and cognitive impairment after stroke are associated with physical functional outcomes, but there are limited data on whether depressive symptoms and cognitive status and improvements independently influence functional status and recovery.

Saliva eosinophil cationic protein (ECP) is higher in asthmatic adults than in healthy ones. However, its relationship with asthma severity, other atopic conditions and allergic sensitization have not been reported. Saliva collection is painless, readily acceptable to children and parents, and can be a potentially useful body fluid to measure asthma(More)
