The objective of the study is to investigate the propagation of Ca(2+) waves in full-width cardiac myocytes and carry out sensitivity analysis to study the effects of various physiological parameters on global Ca(2+) waves. Based on the anomalous subdiffusion of Ca(2+) sparks, a mathematical model was proposed to characterize the Ca(2+) waves. The computed results were in agreement with the exp...

Introduction Cardiac excitation–contraction coupling is a transduction cascade that results in muscle contraction and relaxation. In ventricular myocytes, the arrival of an action potential activates sarcolemmal L-type Ca channels, and the subsequent inward Ca current, in turn, activates several RyRs in the SR membrane (the Ca release unit [CRU]). Activation of a CRU causes more Ca to be releas...

Senegal is a country of the Sahel. In this region, most populations live from agro-pastoral activities. The northern zone strongly influenced by river cultures. And dynamics River are dependent on rainfall. rainfall in area very closely linked to atmosphere. study spatio-temporal variability region requires quality observation data. It includes Ferlo and valley, particular regions Louga (depart...
