Abstract:
We evaluated changes in DNA synthesis, structure, and mechanical activity in isolated arteries during exposure to growth factors. Renal arteries were isolated from rats, sympathectomized, denuded of endothelium, and maintained in tissue culture. Up to 4 days of culture did not affect maximal contractile responses to depolarization. From the results of nuclear incorporation of the thymidine analogue 5-bromo-2-deoxyuridine (BrdUrd), culture stimulated DNA synthesis. In the media, incorporation of BrdUrd was maximal after 3 days but fell precipitously thereafter. Culture of arterial segments did

The objective of the study was to establish the correlation between serum selenium concentrations, total antioxidant status, and the carotid intima media thickness in ultrasound assessment in patients with arterial hypertension.

Abstract:
The relative role of the arterial lumen, adventitial vasa vasorum, and medial vasa vasorum in nutritional support of arteries is unclear. We have used a newly developed autoradiographic method to study diffusion of metabolically inert [14C]antipyrine into arteries to determine the relative importance of different pathways in nutritional support of arteries. [14C]antipyrine was homogenously distributed across the media of small arteries within 15 s, which indicates that diffusion into the central media was rapid. In the thoracic and abdominal aorta, levels of antipyrine were higher in the inner

ABSTRACT:Discontinuous non-circumferential lesions of tunica media were observed in four cases of traumatic rupture of the vertebral artery.

To test this hypothesis, healthy vertebral arteries were incubated with crude extracts of bovine smooth muscle cytosol in attempt to reproduce the histological changes of the arterial media in traumatized vertebral arteries.

Abstract:
Arteries display highly nonlinear, anisotropic material behavior and can be considered to be a layered composite of fiber oriented materials composed of three layers: intima, media and adventitia. The intima does not affect the material properties of the artery. Thus, the mechanical properties of an artery result from the combined interaction of the media and adventitia with each layer displaying different material properties. It has been widely accepted that atherosclerosis changes the material properties of the arterial wall. However, little experimental data exists relating the properties o

Abstract:
Changes in medial elastin are critical to arterial remodeling following a sustained increase in blood flow, wherein the lumen enlarges in two phases tending to restore the intimal shear stress to control: 1st, via rapid smooth muscle relaxation and, 2nd, via chronic reconstruction of the media [1]. At the same time, wall thickening takes place aiming at restoring the baseline levels of wall stress [2].

Abstract:
Percutaneous transluminal angioplasty (PTA) can lead to vascular damage when used to treat atherosclerotic obstructions and vasospasm in cerebral vessels [1–3]. In a controlled study of angioplasty in normal arteries of mongrel dogs, changes to the arterial wall due to over inflation were studied at two dilation levels (24%,50%) [4]. Damage to the wall was progressive — increasing with inflation level. At 25% inflation, localized fractures and stretching of the internal elastic lamina (IEL) were observed. Damage to the media was limited to the inner one-third of the wall. At 50% inflation, fur

Abstract:
The present paper introduces in vivo measurements of viscoelasticity of arterial wall developed in our laboratory. The endothelial dysfunction is considered to be an earliest stage of atherosclerosis. Moreover, it was reported that the smooth muscle, which constructs the media of the artery, changes its characteristics due to atherosclerosis. Therefore, it is essential to develop an in vivo measurement method to assess the regional endothelial function and mechanical property (viscoelasticity) of the arterial wall. To evaluate the endothelial function, there is a conventional technique for mea

Abstract:
In a wide range of biomechanical modeling of aorta from traumatic injury to stent grafts, the arterial wall has been considered as a single homogeneous layer vessel, ignoring the fact that arteries are composed of distinct anatomical layers with different mechanical characteristics. In this study, using a custom-made nanoindentation technique, changes in the mechanical properties of porcine thoracic aorta wall in the radial direction were characterized using a quasi-linear viscoelastic model. Two layers of equal thickness were mechanically distinguishable based on the radial variations in the
