Numerical modeling of the flow in stenosed coronary artery. The relationship between main hemodynamic parameters
The severity of coronary arterial stenosis is usually measured by either simple geometrical parameters, such as percent diameter stenosis, or hemodynamically based parameters, such as the fractional flow reserve (FFR) or coronary flow reserve (CFR). The present study aimed to establish a relationship between actual hemodynamic conditions and the parameters that define stenosis severity in the c...
متن کاملSquare-root relations between main saccadic parameters.
PURPOSE To derive and evaluate two equations in which saccade duration and peak velocity are proportional to the square root of saccade amplitude. METHODS A population of horizontal visually guided saccades in a range of amplitudes from 1.5 degrees to 30 degrees was recorded by means of electro-oculography in eight normal adult subjects. The peak velocity-amplitude data of this population wer...
متن کاملSquare-Root Relations Between Main Saccadic Parameters
Methods. A population of horizontal visually guided saccades in a range of amplitudes from 1.5° to 30° was recorded by means of electro-oculography in eight normal adult subjects. The peak velocity-amplitude data of this population were fitted to four models: inverse linear, exponential, power law, and square root. To approximate the duration-amplitude relation, the square root was tested again...
متن کاملRelationship between serum uric acid levels and intrarenal hemodynamic parameters.
BACKGROUND/AIMS Hyperuricemia has been reported to affect renal hemodynamics in rat models. We evaluate the relationship between serum uric acid and intrarenal hemodynamic parameters in humans, utilizing the plasma clearance of para-aminohippurate (CPAH ) and inulin (Cin). METHODS Renal and glomerular hemodynamics were assessed by simultaneous measurement of CPAH and Cin in 58 subjects. Of th...
متن کاملRelations between ameboid movement and membrane-controlled electrical currents
We have studied the pattern of electrical currents through amebas (mainly Chaos chaos) with an ultrasensitive extracellular vibrating probe. Amebas drive both steady currents and current pulses through themselves. Relatively steady current with an average surface density of 0.1-0.2 muA/cm2 enters the rear quarter of an ameba and leaves its pseudopods. Streaming reversals are preceded by changes...
