Down-Expression of Kinin Receptors in Allergic Nasal Polyps Epithelia: An Immunohistochemistry Study.

Objectives: To investigate the expression of B1 and B2 receptors in patients with nasal polyps (NPs) compared to controls.

Study Design: Retrospective case series.

Settings: Single academic center.

Imaging of the age-related anatomical relationship between the innominate artery and the trachea.

Purpose: To measure the age-dependent changes of anatomical positions and relations between the trachea, cricoid cartilage (CC), and innominate artery (IA) in adults by computed tomography (CT).

Methods: A retrospective cohort reviewing images of 127 consecutive adult patients who underwent CT angiography (CTA) of the neck. The trachea-to-IA (T-IA) distance was measured as the minimal horizontal distance between them.
