The aim of this study was to evaluate the theoretical possibility of assessing the architecture of the coronary small artery circulation in vivo by the analysis of the increments in the total resistance of the vascular system caused by the progressive occlusion of the terminal vessels as would be possible in animal experiments by microsphere embolization.(More)
The aim of this study is to assess vascular architecture and the single vessel resistance distribution of the subepicardial (epi) and subendocardial (endo) layers of the left ventricular wall. For this purpose, coronary embolization was performed by injecting three boluses of 25 microns plastic microspheres into the maximally vasodilated left circumflex(More)
This paper describes an application of the ORBCOMM satellite system for helping pleasure-boat sailors to navigate. The IntraCoastal Satellite Communication System (ICSCS) is an improvement on the well established ChartPlotter made by Geonav 11E Navionix for bidirectional coastal communication. By using a terminal of the ORBCOMM system, ICSCS allows the(More)
Experiments were performed to test whether melatonin plays a role in sun-compass orientation of homing pigeons. Birds were kept for a period of time in dim continuous light (LL) or in artificial light-dark (LD) cycles and then released under the sun from unfamiliar sites. Control birds in dim LL were oriented homeward in all cases. Birds with melatonin(More)
The architecture and resistance distribution of the coronary arteriolar tree downstream 100 mu diameter vessels are still largely unknown, due to technical difficulties in direct visualization. In this study we propose a mathematical model of the architecture and the single vessel resistance distribution of terminal arteriolar vasculature in the beating dog(More)
