Experiences with the computational modelling of the contact between the hip joint endoproshesis head and cup with production inaccuracies
Fuis, Vladimír
The paper presents the experiences with the computational modelling of the forces on the inner spherical area of the polyethylene cup of the total hip joint endoprosthesis with consideration of the production inaccuracies (different cup's diameters).
Computational modelling of the influence of area tolerance on the contact pressure between the hip joint endoprosthesis parts
Fuis, Vladimír ; Krbec, M. ; Florian, Z.
The paper presents the experiences with the computational modelling of the forces on the inner spherical area of the polyethylene cup of the total hip joint endoprosthesis with consideration of the production inaccuracies (different cup's diameters).
Effect of modulation of ionic channel conductivities on restitution processes in cardiac cells (Computer modelling)
Pásek, Michal ; Šlichta, J.
The restitution properties of cardiac action potential were shown to be important determinants of stability of reentrant arrhythmias. The restitution hypothesis states that steeply sloped restitution curves (relations between action potential duration and preceding diastolic interval) induce unstable wave propagation that results in wave break, the event that leads to fibrillation. In this contribution we try to explore the effect of modulation of membrane channel conductuvities on electrical restitu**n curves by means of computer modelling.
The quantitative exploration of refractory period in human atrial cells
Brožková, K. ; Pásek, Michal ; Šlichta, J.
The refractory period of cardiac cell plays a significant role in process of suppression of cardiac arrhythmias. The aim of this study is to explore the refractory period of human atrial cells. The method used in this work is based on quantitative modelling.
Computer modelling of effect of transversal tubules on excitation - contraction coupling in cardiac cells (Basic study)
Pásek, Michal ; Christé, G. ; Šimurda, J.
The transverse tubular system (T-system) of cardiac muscle is a structure that allows rapid propagation of excitation into the cell interior. As suggested in many resent experimental works it could have a significant effect on cardiac cell function in **ed by the accumulation or the depletion of ions in restricted tubular space. The aim of our work was to design a mathematical model of electrical activity of cardiac cell including a quantitative description of T-system function and to explore the phy
