We have previously demonstrated that arterial other molecular weight (Mr ) separated under reducing or nonreducing conditions, suggesting antigens derived from the aorta of spontaneously that these molecules are not subunits of larger hypertensive rats (SHRs) stimulate arterial proteins and may represent monomeric antigens antigen-reactive T cell clones established from the polymerized into the...

1. Cholesterol esterification and accumulation in the arterial wall is a hallmark of atherogenesis. Several preclinical studies suggest that calcium antagonists may exert antiatherosclerotic activity by directly affecting atherogenesis in the arterial wall. We investigated the effect of the second generation dihydropyridine calcium antagonist lacidipine on cholesterol metabolism in vivo in the ...

The purpose of this study was to determine the influence of radial motion of an arterial wall on the shear stress that flowing blood imposes on the wall (wall shear stress). Wall shear stress is known to influence endothelial cell function and may play a role in atherogenesis, but its magnitude and distribution in the circulation are not well understood. To simulate arterial wall motion, we use...

Research on wave propagation in liquid-filled vessels is often motivated by the need to understand arterial blood flow. Theoretical and experimental investigation of the propagation of waves in flexible tubes has been studied by many researchers. The analytical one-dimensional frequency domain wave theory has a great advantage of providing accurate results without the additional computational c...

PURPOSE To present a HOmologous Black-Bright-blood and flexible Interleaved imaging (HOBBI) sequence for dynamic contrast-enhanced magnetic resonance imaging (MRI) of the vessel wall. THEORY AND METHODS A HOBBI sequence is proposed to acquire high-spatial-resolution black-blood and high-temporal-resolution bright-blood dynamic contrast-enhanced images in an interleaved fashion. Black-blood im...

BACKGROUND Arterial remodeling in response to atherosclerosis may be outward (positive) or inward (negative) and is an important mechanism in the clinical manifestations of atherosclerosis and restenosis after percutaneous coronary interventions. Postmortem and intravascular ultrasound studies of arterial remodeling do not allow serial and noninvasive data to be obtained. In a rabbit model of a...

Introduction:In this study, a non-invasive method based on consecutive ultrasonic image processing is introduced to assess time rate changes of the carotid artery wall displacement, velocity and acceleration in the longitudinal direction. The application of these parameters to discriminate healthy and atherosclerotic arteries was evaluated. Methods:Longitudinal displacement rate of common ...
