Papillary muscle and left ventricle show different contractile and metabolic responses during myocardial stunning
Autor: C J, Zuurbier, J H, van Beek
Publikováno v: Advances in experimental medicine and biology. 454
We conclude that a global ischemic/hypoxic insult results in a heterogeneous response of mechanical and mitochondrial performance in isolated Langendorff-perfused hearts. The results warn against the use of models of stunning in which stunning is det

The dynamic regulation of myocardial oxidative phosphorylation: analysis of the response time of oxygen consumption
Autor: J H, van Beek, X, Tian, C J, Zuurbier, B, de Groot, C J, van Echteld, M H, Eijgelshoven, J B, Hak
Publikováno v: Molecular and cellular biochemistry. 184(1-2)
Although usually steady-state fluxes and metabolite levels are assessed for the study of metabolic regulation, much can be learned from studying the transient response during quick changes of an input to the system. To this end we study the transient

A mathematical model for the heterogeneity of myocardial perfusion using nitrogen-13-ammonia
Autor: K R, Visser, J G, Meeder, J H, van Beek, E E, van der Wall, A T, Willemsen, P K, Blanksma
Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 39(8)
Heterogeneity of left ventricular myocardial perfusion is an important clinical characteristic. Different aspects of this heterogeneity were analyzed.The coefficient of variation (v), characterizing heterogeneity, was modeled as a function of the num

Function of isolated rabbit hearts perfused with erythrocyte suspension is not stable but improvement may be feasible with hemoglobin solution
Autor: J B, Hak, P T, Biessels, J H, van Beek, J C, Bakker, N, Westerhof
Publikováno v: Advances in experimental medicine and biology. 345
In the present study isolated rabbit hearts were perfused with erythrocyte suspensions (hematocrit 21.5 +/- 0.5%) or hemoglobin solutions according to Langendorff with a constant flow at 37 degrees C. In preliminary experiments three types of stroma-

The microvascular unit size for fractal flow heterogeneity relevant for oxygen transport
Autor: J H, van Beek, J P, Barends, N, Westerhof
Publikováno v: Advances in experimental medicine and biology. 345
In this study we used a computer model for oxygen transport in heterogeneously perfused tissue to define the microvascular unit size of relevance to oxygen transport. Flow within this unit is presumably heterogeneous, but this internal heterogeneity
