...J.C. Ribeiro-Silva; A.A. Miyakawa; Jose E. Krieger Smooth muscle cell (SMC) contractility is essential to vessel tone maintenance and blood pressure regulation. In response to vasoconstrictors, calcium-dependent mechanisms promote the activation of the regulatory myosin light chain, leading...

...) infusion prevents HG + ISO-induced cardiac dysfunction. We found that insulin rescued proper cardiac redox balance, but not mitochondrial respiration or contractile performance. Conversely, Palm restored redox balance and preserved myocyte function. Thus, stressors such as peaks of HG and adrenergic...

... patients with normal ventricular function underwent two dipyridamole echocardiography tests, and 11 with regional contractility defects from previous myocardial infarction were submitted to two ECG exercise tests combined with 201 Tl myocardial perfusion scintigraphy; the tests were preceded by 60 min...

... and regional ischaemia of the posterior wall. These parameters were compared with global contractility [E ES (end-systolic elastance)] measured by a conductance catheter. Ischaemia was induced by an active coronary hypoperfusion in the circumflex coronary artery. Measurements were done at baseline, during...

For example, papillary muscles exposed to serum obtained from patients with chronic anaemia exhibit increased contractility P21. Although the effects of iron deficiency on the overall cardiovascular...

.... The media thickness in both veins increased rapidly, reaching a maximum at 14 days (82%, oesophageal; 56%, mesenteric) and thereafter decreasing. 4. The contractility of oesophageal veins was transiently decreased (at 4 days), while that of the mesenteric veins was transiently increased (at 14 days). 5...
