Impaired Diffusion Coupling-Source of Arrhythmia in Cell Systems
نویسندگان
چکیده
A detailed analytical and numerical analysis of a simple reaction-diffusion model of the source of non-homogeneities and arrhythmias in an originally homogeneous reaction system is pre sented. Solution, bifurcation and evolution diagrams are used to describe the behaviour of the model. It is shown that under certain conditions steady and/or oscillatory nonhomogeneous states are the only stable solutions of the model. These phenomena are essentially not dependent on a particular reaction kinetics. A possible relevance to some biological situations is discussed.

Lattice Boltzmann modeling of two component gas diffusion in solid oxide fuel cell
In recent years, the need for high efficiency and low emission power generation systems has made much attention to the use of fuel cell technology. The solid oxide fuel cells due to their high operating temperature (800 ℃ -1000 ℃) are suitable for power generation systems.Two-component gas flow (H2 and H2O) in the porous media of solid oxide fuel cell’s anode have been modeled via lattice Boltz...
متن کاملA Quick update from the Past to Current Status of Human Pluripotent Stem Cell-derived Hepatocyte culture systems
Pluripotent stem cells (PSCs) may be offered as an unlimited cell source for the hepatocyte generation. The generation of hepatocytes from stem cells in vitro would provide an alternative cell source for applications in drug discovery and cell transplantation. In this review, we discuss different approaches to generate pluripotent stem cell-derived hepatocytes, advantages, limitations for each ...
متن کاملSodium Current Reduction Unmasks a Structure-Dependent Substrate for Arrhythmogenesis in the Normal Ventricles
BACKGROUND Organ-scale arrhythmogenic consequences of source-sink mismatch caused by impaired excitability remain unknown, hindering the understanding of pathophysiology in disease states like Brugada syndrome and ischemia. OBJECTIVE We sought to determine whether sodium current (INa) reduction in the structurally normal heart unmasks a regionally heterogeneous substrate for the induction of ...
متن کاملOptical mapping of arrhythmias induced by strong electrical shocks in myocyte cultures.
Strong electrical shocks can induce arrhythmias, which might explain why shocks fail to defibrillate. In this work, the localization of arrhythmia source and the relationship with local changes of transmembrane potential (V(m)) were determined in geometrically defined cell cultures using optical mapping technique. Uniform-field shocks with strength (E) of 10 to 50 V/cm were applied across cell ...
