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 …

Myocardial Topical Negative Pressure
… is possible to increase myocardial microvasular blood flow by applying a topical negative pressure source directly onto the myocardium. Topical negative pressure is a relatively new wound healing technique. When used in wound therapy, topical negative pressure has been shown to increase …

The Effects of Short Work Versus Longer Work Periods Within Intermittent Exercise on VO2 Kinetics, Muscle Deoxygenation and Energy System Contribution
… to perform the identical work rate. Enhanced microvascular blood flow facilitated an accelerated matching of total O2 delivery to O2 utilization as well with increased recovery periods.

The Effects of Age and Long-Term Endurance Training on VO2 Kinetics
… the exercise transient; this may reflect a microvascular blood flow limitation. The present study suggests that long-term endurance training can abolish the age-related slowing of τVO2p via improved matching of local O2 delivery to muscle VO2.

Advancing the intravoxel incoherent motion model as a tool for quantifying brain microvascular health
… of the brain with functional measures such as blood flow or cognition in humans, noninvasive techniques are required. One model for measuring microvascular blood flow is the intravoxel incoherent motion (IVIM) model of pseudodiffusive blood flow. In this work, a set of IVIM-derived …

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, …

Negative Pressure Wound Therapy - Mechanisms of Action and Protecting Exposed Blood Vessels in the Wound Bed
… and bleeding when used in wounds with exposed blood vessels. The aims of this work were to investigate the mechanisms of action of NPWT and to explore the possibility of using thin plastic discs to protect exposed blood vessels in the wound bed during NPWT. Three different kinds of wounds were …

Lattice Boltzmann method for integrating the Bloch equation in muscle fibers and microvessels
… been used to obtain measurements of the cerebral blood flow. Blood flow in microvascular vessels plays a vital role in the functional exchange of nutrients essential for healthy development, and toxic waste to be removed from the body, between the blood and tissue. Study of the properties of …

Creatine Monohydrate Supplementation Effects on Oxidative Stress and Blood Flow in Older Adults with Overweight/Obesity
… in reducing ROS concentrations and enhancing blood flow. Therefore, the aim of the dissertation is twofold, first to determine the impact of NOX produced ROS on skeletal muscle microvascular blood flow (SMBF) in older individuals with overweight/obesity. Second, to determine the effect of five …
