Fabrication and testing of a microdynamic rotor for blood flow measurements
microdynamic rotor blood flow measurements
2009/12/23
Flow studies have been conducted, in vitro, on prototype
microfabricated blood flow sensors. The envisioned measurement principle is the
detection of the rotation of a micromachined polysilicon rot...
The Potential Effects of a Biofeedback Writing Exercise on Radial Artery Blood Flow and Neck Mobility
radial artery blood flow cervical range of motion neck trauma biofeedback
2009/10/30
Background:It has been suggested that sustained contraction of the deep neck muscles may reduce axial cervical range of motion (CROM) and radial artery blood flow velocity (vrad.art.mean). No studies ...
Simulations of time harmonic blood flow in the Mesenteric artery: comparing finite element and lattice Boltzmann methods
the Mesenteric artery finite element lattice Boltzmann methods
2010/2/25
Background
Systolic blood flow has been simulated in the abdominal aorta and the superior mesenteric artery. The simulations were carried out using two different computational hemodynamic methods: th...
Cerebral Blood Flow Measurement Using fMRI and PET: A Cross-Validation Study
fMRI PET Cerebral Blood Flow Measurement
2009/9/4
An important aspect of functional magnetic resonance imaging (fMRI) is the study of brain hemodynamics, and MR arterial spin labeling (ASL) perfusion imaging has gained wide acceptance as a robust and...
Development of a Miniaturized Fiber-optic Laser Doppler Velocimetry Sensor for Local Blood Velocity Measurement—Measurement of Velocity Profile of Pulsatile Blood Flow in Model Vessel—
fiber-optic LDV sensor pulsatile flow opaque fluid local velocity measurement flow
2009/6/8
In order to measure local velocity in a pulsatile flow, the optical system and the curvature of the fiber sensor tip were improved. The fiber sensor was inserted at an insertion angle of 120 deg. thr...
Visualization of Thrombus Formation Process and Flow Analysis on Shear Blood Flow
Thrombus Shear rate Concentration Pulsatile flow
2009/6/5
This paper describes the visualization of thrombus formation process by using the plasma water to develop the CFD based prediction method of thrombus formation. The experimental apparatus has one ori...
Ingestion of bonito extract ameliorates peripheral blood flow in mice loaded from over crowding stress
peripheral blood crowding stress
2009/5/8
Bonito extract (BE) has been shown to improve various fatigue-related symptoms. The possibility that the improvement of blood flow contributes to the improvement of fatigue-related symptoms has been...
Comparison of Intraocular Pressure Fluctuations Measured by Goldmann Applanation Tonometer and Pulsatile Ocular Blood Flow Analyser
glaucoma intraocular pressure Goldmann applanation tonometry pulsatile ocular blood flow analyser
2009/4/20
Evaluation of the effect of glaucoma medication is restricted by measurement of IOP as a dynamic physiological parameter. Present paper aimed to compare IOP fluctuations over time using Goldmann appla...
A model of blood flow in the mesenteric arterial system
blood flow the mesenteric arterial system
2010/2/26
The computational model developed shows close agreement with physiologically realistic geometries other researchers have recorded in vivo. Using this model as a framework, results were analyzed for th...
Stress analysis in a layered aortic arch model under pulsatile blood flow
Stress analysis a layered aortic arch model pulsatile blood flow
2010/2/26
Our analysis indicates that circumferential stress in the aortic wall is directly associated with blood pressure, supporting the clinical importance of blood pressure control. High stress in the aorti...
Computational model of blood flow in the aorto-coronary bypass graft
blood flow the aorto-coronary bypass graft
2010/3/1
The computed results have revealed that (i) maximum perfusion of the occluded artery occurs during mid-diastole, and (ii) the maximum wall shear-stress variation is observed around the distal anastomo...
Computational studies of the effects of myocardial blood flow reductions on cardiac metabolism
myocardial blood flow cardiac metabolism
2010/3/1
Changes in phosphorylation state and glucose uptake only significantly affect the initial phase of the glycolytic response to ischemia, while glycogen breakdown exerts control over glycolysis during t...
