Carotid collar : a device for auscultory detection of carotid artery stenosis
The carotid collar is a hardware device designed to aid in detecting carotid artery stenosis, a disease that increases the risk of stroke. This device consists of three electronic stethoscopes that record heart and carotid artery sounds and an electrocardiograph. A software application, ccrec, was …

Ultrasound features of human carotid plaques
Atherosclerotic plaques in the carotid arteries are common in a middle-aged population. When a carotid plaque ruptures it may result in a cerebrovascular event. However, only a minor part of carotid plaques will eventually rupture. Finding those plaques is essential to decide the most appropriate …

Haematopoietic progenitor cells in carotid disease
… and mobilising cytokines, reflect significant carotid disease or correlate with restenosis following carotid endarterectomy (CEA). Methods Initially the assay conditions to measure HPC number and function were optimized. HPC numbers were measured by flow cytometry (CD133+ve/CD34+ve) and early …

Predictive haemodynamics of the human carotid artery
… parametrically defined geometry of the human carotid artery bifurcation to better understand the relationship between a range of parameters and the associated haemodynamics and to devise strategies to provide guidance for clinical interventions and to assist in the design of stents and grafts. …

Computational analysis on stent geometries in carotid artery
… for treating the narrowed artery or stenosis in carotid artery to restore blood to the brain. However, the restenosis process is usually observed after a few weeks of carotid stenting due to abnormal progression of atherosclerosis and thrombosis. Many studies reported that the activity of …

Vitamin D, ADAM-12 and Carotid Artery Disease
… and cell counting.|Vitamin D-deficient swine carotid artery VSMCs expressed more ADAM-12, released more HB-EGF, and had higher levels of EGFR phosphorylation was increased compared to D-sufficient and D- supplemented swine VSMCs. Treatment of VSMCs with ADAM-12 siRNA inhibited ADAM-12 …

Transcriptome and Functional Analysis of Carotid Body Glomus Cells
<p>The carotid body (CB) is a major arterial chemoreceptor containing glomus cells that are activated by changes in arterial blood contents including oxygen. Despite significant advancement in the characterization of their physiological properties, our understanding on the underlying molecular …

Magnetic Resonance Imaging of Susceptibility Effects in Carotid Atherosclerosis
… susceptibility mapping (QSM), to characterize carotid artery plaques with and without the use of ultrasmall superparamagnetic iron oxide (USPIO) nanoparticle contrast agents. The overall hypothesis is that QSM can serve to differentiate carotid artery plaque features of different susceptibility …

Stabilised decellularised vascular grafts in an ovine carotid model
… were implanted as interposition grafts into the carotid arteries of 6 sheep, using industry standard 6mm expanded polytetrafluoroethylene (ePTFE) on the contralateral side of each animal as control. In-situ patency was determined by ultrasound and angiography at two months, following which the …

Ex-vivo 3D assessment of carotid stenosis with ultrasound
… of arterial structure and composition in the carotid vessel wall. It has been shown that the progression of the disease can be monitored by tracking changes in the carotid intima-media thickness (IMT). Non-invasive peripheral vascular ultrasound (U/S) of the carotid artery is a non-invasive, …

Carotid Atherosclerosis: Why Some Patients are Symptomatic and Others Not?
… and mortality in the United States. OVD of the carotid arteries results in stroke or transient ischemic attacks. A significant number of strokes are caused by carotid artery atherosclerosis. Atherosclerosis, commonly referred to as "hardening of the arteries," is a disease where there is build …

Three-dimensional Quantitative Magnetic Resonance Imaging of Carotid Atherosclerotic Plaque
… with 20% of ischemic strokes attributed to carotid atherosclerosis. In recent years, morphological characteristics of atherosclerotic plaque such as a thin fibrous cap, large lipid-rich necrotic core, intraplaque haemorrhage and ulceration have shown correlations with subsequent clinical …

Sympathetic control of carotid body excitability in hypertension: A preclinical study
… studies have demonstrated that the integrity of carotid bodies is essential for the development and maintenance of hypertension via exacerbated sympathetic drive. Carotid bodies of spontaneously hypertensive (SH) rats exhibit both hypertonicity and hyperreflexia (i.e., hyper-excitability), which …

Longterm peripheral baroreflex and chemoreflex function after bilateral eversion carotid endarterectomy
Introduction The “eversion” technique for carotid endarterectomy (e-CEA), that involves the transection of the internal carotid artery at the carotid bulb and its eversion over the atherosclerotic plaque, has been associated with an increased risk of postoperative hypertension possibly due to a …
