Wave propagation in stenotic vessels; theoretical analysis and comparison between 3D and 1D fluid-structure-interaction models [PDF]
, 2019 Using analytical expressions for the pressure and velocity waveforms in tapered vessels, we construct a linear 1D model for wave propagation in stenotic vessels in the frequency domain. We demonstrate that using only two parameters to approximate the exact geometry of the constriction (length and degree of stenosis), we can construct a model that can ...

The effect of varying degrees of stenosis on transition to turbulence in oscillatory flows [PDF]
arXiv, 2022 Many complications in physiology are associated with a deviation in flow in arteries due to a stenosis. The presence of stenosis may transition the flow to weak turbulence. The degree of stenosis as well as its configuration whether symmetric or non-symmetric to the parent artery influences whether the flow would stay laminar or transition to ...

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.ABSTRACT Patients with Turner Syndrome (TS) and those exposed to high concentrations of glucocorticoids have a number of characteristics in common, including an increased risk of cardiovascular disease. Pediatric TS patients underwent studies of salivary cortisol (SC) and cortisone (SCn), body composition, continuous glucose monitoring, vascular ...

Ultrasonographic Screening of the Carotid Artery in Coronary Artery Bypass Surgery [PDF]
Journal of Tehran University Heart Center, 2009 Background: The incidence of stroke after coronary artery bypass grafting (CABG) is between 0.9% and 6.7%, which significantly increases in-hospital and out-hospital costs.

The identification of the vulnerable carotid plaque and haemodynamic compromise of the brain in carotid artery stenosis [PDF]
, 2019 Introduction: Carotid stenosis plays a large role in the aetiology of ischaemic stroke. The main mechanism of carotid stenosis causing stroke is the forming of thrombus and consequently embolus formation.

Prosthetic bypass for restenosis after endarterectomy or stenting of the carotid artery [PDF]
, 2017 OBJECTIVE: The objective of this study was to evaluate the results of prosthetic carotid bypass (PCB) with polytetrafluoroethylene (PTFE) grafts as an alternative to carotid endarterectomy (CEA) in treatment of restenosis after CEA or carotid artery ...

Animal Models and Experimental Medicine, EarlyView.Our study used behavioral tests, laser speckle flowmetry, long‐term potentiation, histochemical staining, molecular experiments, and voxel‐based morphometry to evaluate the hippocampal impairments. It demonstrates early functional and structural impairments in the hippocampus contributing to learning and memory deficits after 1 month of BCAS ...

3-D Registration on Carotid Artery imaging data: MRI for different timesteps [PDF]
2016 38th Annual International Conference of the IEEE Engineering
in Medicine and Biology Society (EMBC), 2016 A common problem which is faced by the researchers when dealing with arterial carotid imaging data is the registration of the geometrical structures between different imaging modalities or different timesteps. The use of the "Patient Position" DICOM field is not adequate to achieve accurate results due to the fact that the carotid artery is a ...
