Cardiac ion channels in health and disease.
Cardiac electrical activity depends on the coordinated propagation of excitatory stimuli through the heart and, as a consequence, the generation of action potentials in individual cardiomyocytes. Action potential formation results from the opening and closing (gating) of ion channels that are expressed within the sarcolemma of cardiomyocytes. Ion channels possess distinct genetic, molecular, ph...
متن کاملMechanisms linking Mental Health Problems and Cardiac Disease: A Review
Psychological problems play a critical role in development of cardiovascular disease. Several mechanisms were suggested to explain the association and mechanism of this effect, recently. Knowledge of the mechanisms mediating the association between psychological status and heart disease could help in developing treatments. The effects of mind and mood on the cardiovascular system can be due to ...

نظر به اهمیت و تاثیر روزافزون عوامل روانی – اجتماعی در سلامت جسمی و تاثیر عوامل روان شناختی در بروز بیماریهای مختلف از جمله بیماریهای قلبی و عروقی این پژوهش با هدف کلی بررسی ارتباط تیپ شخصیتی d ، حمایت اجتماعی و خود دلسوزی در پیش بینی رفتارهای بهداشتی بیماران کرونر قلبی و تعیین تفاوت بین بیماران کرونر قلبی با و بدون جراحی و افراد سالم در این متغیرها و رفتارهای بهداشتی آنان، انجام گرفت. جامعه آ...
15 صفحه اولInactivation of voltage-gated cardiac K+ channels.
Inactivation is the process by which an open channel enters a stable nonconducting conformation after a depolarizing change in membrane potential. Inactivation is a widespread property of many different types of voltage-gated ion channels. Recent advances in the molecular biology of K+ channels have elucidated two mechanistically distinct types of inactivation, N-type and C-type. N-type inactiv...
متن کاملCaMKII regulation of cardiac K channels
Cardiac K channels are critical determinants of cardiac excitability. In hypertrophied and failing myocardium, alterations in the expression and activity of voltage-gated K channels are frequently observed and contribute to the increased propensity for life-threatening arrhythmias. Thus, understanding the mechanisms of disturbed K channel regulation in heart failure (HF) is of critical importan...
