Four Dimensional (4-D) BioChemInfoPhysics Models of Cardiac Cellular and Sub-Cellular Vibrations (Oscillations)

Cellular and Sub-cellular Models of Excitable Cells

Cellular and subcellular mechanisms of cardiac pacemaker oscillations.

Rhythmic oscillations in the membrane potential of heart cells are important in normal cardiac pacemaker activity as well as cardiac arrhythmias. Two fundamentally different mechanisms of oscillatory activity can be distinguished at the cellular and subcellular level. The first mechanism, referred to as a surface membrane oscillator, can be represented by a control loop in which membrane potent...

Leader Election by d Dimensional Cellular Automata

Leader Election by d Dimensional Cellular Automata

We present a cellular algorithm in O(w) for the leader election problem on a finite connected subset F of ZZ of excentricity w, for any fixed d. The problem consists in finding an algorithm such that when setting the elements of F to a special state, and all the others to a state #, the cellular automaton iterates a finite number of steps and eventually sets only one precise element of F to a s...

Vitamin D suppresses cellular pathways of diabetes complication in liver

Objective(s): The aim of this study was to investigate the effect of vitamin D on glucose metabolism, as well as the expression of five key genes involved in the development of diabetes complications in liver tissue of diabetic rats. Materials and Methods: Twenty-four male Sprague–Dawley rats were randomly divided into three groups (8 ra...
