Mechano-electric heterogeneity of the myocardium as a paradigm of its function
Myocardial heterogeneity is well appreciated and widely documented, from sub-cellular to organ levels. This paper reviews significant achievements of the group, led by Professor Vladimir S. Markhasin, Russia, who was one of the pioneers in studying and interpreting the relevance of cardiac functional heterogeneity
Kidney Disease and Perinatal Programming of Arterial Hypertension: the Results of Experimental Researches
Deterioration of development conditions in the perinatal period (starvation of the mother, excess sodium ions in her diet, exposure to glucocorticosteroids, placental insufficiency) programs significant changes in the excretion of sodium ions in the newborn and leads to the development of hypertension. Studies on experimental animals show that unfavourable conditions of intrauterine development can reduce the effective area of glomerular filtration and its rate. These circumstances increase the expression of membrane carriers of sodium ions in the apical membranes, the production of superoxide radicals and enhance the reabsorption of sodium. The article discusses the potential mechanisms of perinatal programming of renal hypertension in humans
