One approach to implementation of low-phase-noise integrated fixed-frequency local oscillators (LOs) for use as the RF LO in a blockdown-convert receiver architecture for PCS wireless communications down-converts the entire RF band to a lower frequen

Airway wall remodeling in response to inflammation might alter load on airway smooth muscle and/or change airway wall stability. We therefore determined airway wall compliance and closing pressures in an animal model. Weanling pigs were sensitized to

1. In rodent models, Sephadex produces pulmonary inflammation that may be associated with bronchial hyperresponsiveness. In the present study we examined whether Sephadex-induced inflammation altered airway narrowing in pigs. 2. Twenty millilitres of

Models of airway function indicate that responsiveness (flow reduction) to bronchoconstrictor provocation depends on airway smooth muscle shortening and airway wall morphology. The contribution of these factors to the responsiveness of central and pe

In cartilaginous bronchi, the smooth muscle is attached to the adventitial cartilage by a fibro-elastic matrix. In pigs, this matrix is stretched during muscle contraction so the inner airway wall reversibly uncouples from the outer wall. We hypothes

Studies in small non-cartilaginous airways suggest that the cross sectional area of the airway wall (comprising the smooth muscle and mucosa) is unaltered during the contraction–relaxation cycle produced by bronchial provocation. In the present stu

Bronchoalveolar ravage (BAL) fluid was collected from control ponies and from affected ponies with heaves which were in clinical remission. Significant differences were not detected between the two groups in total nucleated cell count or relative per

Airway obstruction and hyperreactivity are characteristics of human asthma and of "heaves," a naturally occurring respiratory disorder of horses and ponies. We measured pulmonary function and plasma immunoreactive 15-hydroxyeicosatetraenoic acid (i15
