This thesis sought to examine the influence of the vascular bed on the tissue response to endovascular stent implantation. Closed form analytic solutions were obtained for the different beds studied. Ideal arteries were considered of normal, tapered, curved, or eccentric morphology. The application of the stent boundary conditions in the appropriate defining equations produced the desired strai...

An equivalent static method is employed in calculating the impact response of vessel-bridge collisions, which dynamic characteristics collisions are ignored. spectrum for design proposed according to principle earthquake spectrum. The force time-histories obtained through a numerical simulation using finite element software. relationship between displacement amplification factor single-degree-o...

This paper reviews the use of texture analysis in studying the performance of hydrophilic matrices of highly soluble drugs and different types of excipients (i.e. water-soluble, water-insoluble and swellable, and water insoluble and non-swellable). Tablets were prepared by direct compression, and their swelling and erosion in presence of these different excipients were assessed with the help of...

polyarteritis nodosa is a multisystem necrotizing vasculitis of small and medium size muscular arteries in which involvement of the renal and viserat arteries is characteristic. the etiology is unknown but hepatitis b antigenemia is found in 30% of patients. drug exposures and hypersensitivity reactions are other possible causes. excellent therapeutic results have been reported in classic polya...

Carotid paragangliomas are usually slowly enlarging and painless lateral neck masses. These mostly benign lesions are recognized due to their typical location, vessel displacement and specific blood supply, features that are usually seen on different imaging modalities. Surgery for carotid paraganglioma can be associated with immediate cerebrovascular complications or delayed neurological impai...

Animals exposed to anthropogenic disturbance make trade-offs between perceived risk and the cost of leaving disturbed areas. Impact assessments tend to focus on overt behavioural responses leading to displacement, but trade-offs may also impact individual energy budgets through reduced foraging performance. Previous studies found no evidence for broad-scale displacement of harbour porpoises exp...

This is a study of the fluid-structure interaction between the stationary Stokes flow of an incompressible, Newtonian viscous fluid filling a three-dimensional, linearly elastic, pre-stressed hollow tube. The main motivation comes from the study of blood flow in human arteries. Most literature on fluid-structure interaction in blood flow utilizes thin structure models (shell or membrane) to des...

RESULTS: The ATC provided consistently stable environmental and temperature control throughout extended cultures. Live imaging revealed dynamic endothelia with cells migrating throughout the vessel walls, both downstream (with) and upstream (against) the flow direction. Cell-cell junctions were contiguous, indicating a confluent, healthy endothelium with intact cytoskeletons. The cross-sectiona...
