Application of flexible fiberoptic bronchoscopy in the removal of adult airway foreign bodies.

Background: Flexible fiberoptic bronchoscopy is a rapid, cost effective and safe procedure.

Aim: To analyze demographic information and endoscopic findings in adult patients with airway foreign body aspiration and its removal.

Methods: Fifty-seven adults (40 males, 17 females; average age 40 years old) with airway foreign body aspiration were analyzed.

High-fat diet may impair K(ATP) channels in vascular smooth muscle cells.

K(ATP) channel in vascular smooth muscle cell (VSMC) is closely linked to the etiology of hypertension. The aim of this study was to investigate effect of the high-fat diet-induced obesity on K(ATP) channel and blood pressure. Obesity was induced by a 24-week high-fat diet feeding in rats.

Observation of the morphology and calcium content of vestibular otoconia in rats after simulated weightlessness.

Reduction in bone formation may have been the main reason for the lower calcium content of the otoconia after simulated weightlessness in rats. The head-ward distribution of blood volume may explain the morphological changes observed in the middle and inner ears. To observe morphological changes in the vestibular organs and measure the calcium content of otoconia in rats after simulated weightlessness.
