Airway Resistance, Airway Conductance, Specific Airway Resistance, and Specific Airway Conductance in Children [PDF]

Pediatric Research, 1983
In 82 healthy children and in asthmatic children before and during positive allergen provocation test, airway resistance (Raw), airway conductance (Gaw), specific airway resistance (SRaw), and specific airway conductance (SGaw) were measured by body plethysmography during quiet breathing.

Myeloid-associated differentiation marker is a novel SP-A-associated transmembrane protein whose expression on airway epithelial cells correlates with asthma severity

Scientific Reports, 2021
Surfactant protein A (SP-A) is well-known for its protective role in pulmonary immunity. Previous studies from our group have shown that SP-A mediates eosinophil activities, including degranulation and apoptosis.

Reduced Local Response to Corticosteroids in Eosinophilic Chronic Rhinosinusitis with Asthma

Biomolecules, 2020
Eosinophilic chronic rhinosinusitis (ECRS), a subgroup of chronic rhinosinusitis with nasal polyps, is recognized as a refractory eosinophilic disorder characterized by both upper and lower airway inflammation.

Inflammatory cytokines can be monitored in exhaled breath particles following segmental and inhalation endotoxin challenge in healthy volunteers

Scientific Reports, 2022
Particles in exhaled air (PEx) are generated when collapsed small airways reopen during breathing. PEx can be noninvasively collected by particle impaction, allowing the analysis of undiluted epithelial lining fluid (ELF).

Relationship between concavity of the flow-volume loop and small airway measures in smokers with normal spirometry

BMC Pulmonary Medicine, 2022
Background There is increasing evidence of small airway abnormalities in smokers despite normal spirometry. The concavity in the descending limb of the maximum expiratory flow curve (MEFV) is a recognised feature of obstruction and can provide ...

Assessment of the Clinical Diagnosis of Onychomycosis by Dermoscopy

Frontiers in Surgery, 2022
BackgroundAs a common clinical superficial fungal infection, the diagnosis of onychomycosis relies on clinical features, traditional KOH direct microscopy and fungal culture. In recent years, dermoscopy has been widely used in the diagnosis and treatment
