CONTEXT Hypoxia is a major cause of pulmonary hypertension in respiratory disease and at high altitude. Recent work has established that the effect of hypoxia on pulmonary arterial pressure may depend on iron status, possibly acting through the transcription factor hypoxia-inducible factor, but the pathophysiological and clinical importance of this interaction is unknown. OBJECTIVE To determi...
• Elevation of the pulmonary arterial pressure is known to occur during hypoxia in a number of mammalian species. The mechanisms involved in the production of this hypertension are, however, not clearly understood. Most previous investigations have been concerned with the effect of short periods of severe hypoxia upon the pulmonary circulation. The effects of mild, prolonged hypoxia are less we...
the aim of this study was to investigate the effects of dietary garlic on the growth performance, intestinal mucosa morphology, and pulmonary hypertensive response in broiler chickens with pulmonary hypertension induced by 3, 5, 3′-l triiodothyronine. chicks were reared for 42 days and treated with triiodothyronine (1.5 mg/kg diet) and 0 (control), 0.2, 0.6 or 1% garlic powder. intestinal segme...
an elevated pulmonary artery pressure (pap) from any cause is associated with increased mortality, especially in cases of primary pulmonary arterial hypertension (pah). one of the many reasons behind a bad prognosis is the inherent difficulty in assessing right ventricular (rv) function with reproducible methods. intensive research involving the left heart has made it relatively easy to assess ...
