Effect of head posture on the healthy human carotid bifurcation hemodynamics
(2013)Head and neck postures may cause morphology changes to the geometry of the carotid bifurcation (CB) that alter the low and oscillating wall shear stress (WSS) regions previously reported as important in the development of ...

The Effect of Head Rotation on the Geometry and Hemodynamics of Healthy Vertebral Arteries
(2015)The geometric and hemodynamic characteristics of the left and right vertebral arteries (LVA, RVA) of six healthy volunteers were investigated for the supine (S) and the prone position (P) a common sleeping posture with ...

Effect of posture change on the geometric features of the healthy carotid bifurcation
(2009)Segmented cross sectional MRI images were used to construct 3D virtual models of the carotid bifurcation in 5 healthy volunteers. Geometric features such as bifurcation angle, planarity angle, asymmetry angle tortuosity ...

Effect of posture change on the geometric features of the healthy carotid bifurcation
(2011)Segmented cross-sectional MRI images were used to construct 3-D virtual models of the carotid bifurcation in ten healthy volunteers. Geometric features, such as bifurcation angle, internal carotid artery (ICA) angle, ...

First and second order statistical texture features in carotid plaque image analysis: Preliminary results from ongoing research
(2011)Carotid plaques have been associated with ipsilateral neurological symptoms. High-resolution ultrasound can provide information not only on the degree of carotid artery stenosis but also on the characteristics of the ...

Head posture influences the geometric and hemodynamic features on the healthy human carotid bifurcation
(2012)Atherosclerosis is the third leading cause of morbidity and mortality in the Western world. Low and oscillating wall shear stress (WSS) regions have been previously reported as parameters that correlate with the development ...

Impact of head rotation on the individualized common carotid flow and carotid bifurcation hemodynamics
(2014)This paper aims at evaluating the changes that head rotation poses on morphological and flow characteristics of the carotid bifurcation (CB) and on the distribution of parameters that are regarded as important in atherosclerosis ...

The influence of oxygen concentration on the rheological properties and flow of whole human blood
(2016)Variations in blood oxygen concentrations are not only part of the normal physiology but they may also indicate various pathological conditions. In the present work, we examined the influence of oxygen concentration on the ...

The influence of temperature on rheological properties of blood mixtures with different volume expanders-implications in numerical arterial hemodynamics simulations
(2011)During the complicated cardiac surgery on a non-beating heart with cardiopulmonary bypass, protection of the heart is accomplished by injecting cold cardioplegic solutions. In most forms of circulatory shock, it is necessary ...

Is the mortality rate for septic shock really decreasing?
(2008)Survival rates for patients in septic shock have gradually improved in critical care units worldwide over the last 25 years. Further improvement will be predicated on the discovery of new therapies to disrupt the underlying ...
