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 …

Quantitative Cerebrovascular Reserve Measured by Acetazolamide-Challenged Dynamic CT Perfusion in Ischemic Adult Moyamoya Disease : Initial Experience with Angiographic Correlation
… hemispheres. We classified the degrees of distal carotid artery stenosis according to modified Suzuki stage and determined the presence of basal Moyamoya vessels (BMVs). The values of normalized parameters and their PCs were compared with angiographic findings. Normalized baseline mean transit …

Investigation of inflammatory and oxidative stress mechanisms in the disruption of white matter structure and function following chronic cerebral hypoperfusion
… cerebral hypoperfusion (bilateral carotid artery stenosis). There were no differences in the severity of blood flow reductions between genotypes initially, however, wild type mice displayed improved recovery compared to Nrf2 deficient mice. Hypoperfusion induced white matter …

Investigating the role of TREM2 and neuroinflammation in an experimental model of chronic cerebral hypoperfusion
… white matter damage, the bilateral common carotid artery stenosis (BCAS) model of chronic cerebral hypoperfusion was implemented in wild type (WT) and TREM2-/- C57BL/6Ntac mice. Initial studies demonstrated 0.18 mm internal diameter microcoils failed to induce sufficient white matter …

Hypertension, blood pressure, cognition and cerebral blood flow in the cohort of "Men born 1914"
… investigation, ultrasonographic measurement of carotid arteries, 24-hour ambulatory blood pressure monitoring, regional cerebral blood flow, and cardiovascular risk factors. It is well known that hypertension plays a major etiological role in the development of cerebrovascular disease, ischemic …

Improved qualification of vascular abnormalities in contrast enhanced magnetic resonance angiographic images
… stroke is the percentage of the narrowing in the carotid arteries, which lead blood from the heart to the brain, which currently is quantified manually. This project is in collaboration with Blackpool Victoria Hospital and Christies Hospital in Manchester. The aim of this project is to develop …

Characterization of The Vascular Pathology In The Acta2 R258C Mouse Model and Cerebrovascular Characterization of The Acta2 Null Mouse
… by distal occlusion of the internal carotid artery, stenosis of arteries in the Circle of Willis, and straightening of cerebral arteries. Patient samples are scarcely available for analysis, and the few obtained are from end stages of the disease. For these reason, we decided to study …

Identifying Patients at Risk for Hyperperfusion after Carotid Stenting Using CT Perfusion with Acetazolamide Challenge
… hemodynamic impairment who candidate for carotid stent. We investigated whether preprocedural measurement of cerebrovascular reserve (CVR) by using CT perfusion (CTP) with acetazolamide (ACZ) challenge could identify patients at risk for hyperperfusion after CS. For 12 patients with …

Effects of Sex and Aging in the Response to Global Cerebral Hypoperfusion
… modeled in mice using bilateral common carotid artery stenosis (BCAS). Most BCAS studies have used young male mice, overlooking potential age and sex differences in the response to cerebral hypoperfusion. In this study, we induced BCAS in aged male and female mice to examine sex …
