Ie abstract background— obstructive sleep apnea syndrome (osas), characterized by intermittent hypoxia/reoxygenation (ihr), is an independent risk factor for cardiovascular disease. We investigated the underlying molecular mechanisms of this association in a translational study. 8000 mg viagra Methods and results— in a novel in vitro model of ihr, we used hela cells transfected with reporter constructs and dna binding assays for the master transcriptional regulators of the inflammatory and adaptive pathways (nfîºb and hif-1, respectively) to investigate underlying transcriptional events initiated by repeated cell exposure to ihr. Furthermore, we prospectively studied 19 male osas patients (median apnea-hypopnea frequency, 48. 8000 mg viagra 5 episodes per hour; interquartile range [iqr], 28. viagra for sale 5 to 72. 9) and 17 matched normal control subjects. Circulating levels of the proinflammatory cytokine tumor necrosis factor-î± and the adaptive factor erythropoietin were assayed in all subjects at baseline and again after 6 weeks of continuous positive airway pressure therapy in patients. buy viagra online Full blood count was measured as part of a detailed baseline evaluation. Hela cells exposed to ihr demonstrated selective activation of the proinflammatory transcription factor. Effects of viagra for women
