Journal ArticleDOI
TL;DR: In this paper, measurements of flow disturbances in the downstream region of modeled stenoses in a rigid tube, with upstream pulsatile flow are reported, based on the tube diameter and the time-averaged value of upstream centerline velocity.

TL;DR: The mechanism of insulin release from the electroresponsive PDMAPAA gel is associated with electrokinetic flow of solvated insulin with water; that is, transportation process of counterions and water molecules (electroosmosis) in the crosslinked polyelectrolyte gel network.

Journal ArticleDOI
TL;DR: The results suggest that in many cases, major aspects of the behavior of aneurismal hemodynamics for important classes ofAneurysms can be learned from an analysis of steady, non-pulsatile flow, which is simpler and faster to simulate than time-dependent, pulsatile flow.

TL;DR: Mammalian blood in pulsatile flow through a rigid tube has been shown to be anisotropic with regard to its electrical conductivity.
Abstract: Mammalian blood in pulsatile flow through a rigid tube has been shown to be anisotropic with regard to its electrical conductivity. When flow increases there is a rise in conductivity in the longitudinal and a fall in the radial direction. These changes are caused by flow-dependent variations in the orientation of the disk-shaped erythrocytes.

TL;DR: It is concluded that the use of pulsatile flow resulted in improved patient outcome in preserving cardiac function and maintaining better renal and pulmonic function (shorter intubation period) in the early postbypass period.
Abstract: The use of pulsatile flow during cardiopulmonary bypass (CPB) with regard to improved patient outcomes is controversial. We evaluated pulsatile perfusion in pediatric patients undergoing CPB in a clinical setting. Fifty consecutive pediatric patients undergoing open heart surgery for repair of congenital heart disease were prospectively entered into the study and randomly assigned to either the pulsatile perfusion group (group P, n 25) or the nonpulsatile perfusion group (group NP, n 25). Study parameters included intubation time, duration of intensive care unit (ICU) stay and hospital stay, need for inotropic support, preoperative and postoperative enzymes, creatinine, C-reactive protein, blood count, mean urine output, and total drainage. Group P, compared with group NP, had significantly less
