Cyclooxygenase (COX) is an enzyme that converts arachidonic acid to prostanoids. There are two isoforms of COX, namely COX-1 and COX-2. COX-2 is highly inducible by several stimuli and is associated with inflammation. Recent studies have shown that COX-2 is upregulated in the airway epithelium of patients with asthma but ...

PURPOSE: Le Fort III osteotomy and midfacial advancement expand the nasopharynx and potentially increase airway dimensions in patients with syndromic bilateral coronal synostosis. Distraction osteogenesis allows greater midfacial advancement, and may offer more improvement in airway obstruction, compared with the conventional 1-stage procedure. This study aimed to document the effect ...

Asthma and chronic obstructive pulmonary disease (COPD) are diseases of airway inflammation with clinical and physiological similarities, making their differentiation difficult. Airway inflammatory changes are associated with systemic changes. However, no serum marker is known for their differentiation. Therefore, serum interleukin (IL)-1beta levels were determined. Out of a total of ...
