Pulsatile blood flow in the arteries
… partial differential equations for pulsatile flow in a flexible tube. The fluid is assumed to be a Newtonian, incompressible liquid similar to blood. The vessel is modeled as circular in cross section and tapering with increasing distance from the heart. The governing equations are solved …

The Blood Flow and Perceptual Response To Lower Body Resistance Training With and Without Blood Flow Restriction
… low-load resistance exercise in combination with blood flow restriction (BFR) is well studied but less was known about the cardiovascular response. It was also unknown what impact resistance exercise at 15% 1RM with or without BFR would have on the acute and chronic cardiovascular adaptations and …

Parallel algorithms for direct blood flow simulations
Fluid mechanics of blood can be well approximated by a mixture model of a Newtonian fluid and deformable particles representing the red blood cells. Experimental and theoretical evidence suggests that the deformation and rheology of red blood cells is similar to that of phospholipid vesicles. …

Sympathetic neural control of renal blood flow
… in four parts, investigate how total renal blood flow (RBF) and intrarenal blood flow are controlled by these changes in RSNA. While RSNA and RBF both show oscillations at various frequencies, the functional significance and regulation of these oscillations is not well understood. To …

Mathematical modeling of foetal arterial blood flow
… various haemodynamic viriables on common Doppler blood flow velocity waveform indices. The foetal model consists of an number of vascular compartments, cascaded together using electrical transmission line analogies.

Numerical methods for computationally efficient and accurate blood flow simulations in complex vascular networks: Application to cerebral blood flow
… of this interacting cerebral fluids dynamics is blood flow. In the last decades, mathematical modeling and fluid dynamics simulations have become a valuable complementary tool to experimental approaches, contributing to a deeper understanding of the circulatory physiology and pathology. However, …

Enhancing Team Pursuit Performance using Blood Flow Restriction
… TP. This thesis also examined the integration of blood flow restriction (BFR) into high-intensity interval training (HIIT) as an intervention to improve factors related to TP performance. A series of related investigations were conducted with trained cyclists up to the Olympic level. Study One …

Modeling arterial blood flow using radial basis functions
<p>Investigation into the mechanics of blood flow in arteries helps provide insight into the mechanism of cardiovascular disease. As experimental measurements can be difficult, it is of interest to apply numerical simulation to the problem. This thesis examined fluid flow in arteries using a …

Renal blood flow in the conscious, unrestrained rat
… is to test the hypothesis that the rate of renal blood flow remains constant under normal physiological conditions. Methods were developed for long term studies of renal blood flow (using the Doppler flow probe) and blood pressure in the conscious unrestrained rat. Special care was taken to …

Towards imaging cerebral microvascular blood flow using MRI
… capillaries and venules, in which the blood flow velocity is slow (≤ 2 cm/s). The hemodynamic signals, blood oxygenation-level dependent response, cerebral blood flow, cerebral blood volume and cerebral metabolic rate of oxygen are the common surrogate markers to detect brain neural …

ARTERIAL STIFFNESS AND CEREBRAL BLOOD FLOW AMONG OLDER ADULTS
… vascular factors arterial stiffness and cerebral blood flow (CBF) with mild cognitive impairment (MCI). This study analyzes arterial stiffness and CBF as potential pre-clinical factors of AD in the Alzheimer’s Disease Prevention Participant Repository (ADPPR) cohort. There was a total of 91 …

Nonlinear dynamics of blood flow in simple microvascular networks
… oscillations of nodal pressures, hematocrit, and blood velocity can occur in microvascular networks in the absence of biological control. In this paper, both analytical and numerical methods have been used to investigate the nonlinear dynamics of microvascular blood flow in simple networks. First, …

Optical Cerebral Blood Flow Monitoring of Mice to Men
… used to compute tissue oxygen saturation and blood volume (Section 2.13). DCS is a qualitatively different dynamic technique that analyzes rapid temporal fluctuations in tissue-scattered light with a correlation diffusion approach to derive tissue blood flow (Chapter 4). Further, in …

An investigation of liver blood flow in systemic inflammation
… As the liver is hypermetabolic the delivery of blood would appear to be important in critical illness. Liver blood flow has been studied in systemic inflammation but the relative inaccessibility of the portal vein and the hepatic artery has made this a difficult task. The few studies that have …
