Intra-carotid arterial transfusion of circulatory-derived autologous endothelial progenitor cells in rodent after ischemic stroke-evaluating the impact of therapeutic time points on prognostic outcomes.

Stem Cell Res Ther 2020 06 5;11(1):219. Epub 2020 Jun 5.

Division of Cardiology, Department of Internal Medicine, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University, College of Medicine, Kaohsiung, Taiwan.

Background: This study tested the optimal time point for left intra-carotid arterial (LICA) administration of circulatory-derived autologous endothelial progenitor cells (EPCs) for improving the outcome in rat after acute ischemic stroke (IS).

Methods And Results: Adult male SD rats (n = 70) were equally categorized into group 1 (sham-operated control), group 2 (IS), group 3 (IS+EPCs/1.2 × 10 cells/by LICA administration 3 h after IS), group 4 (IS+EPCs/LICA administration post-day-3 IS), group 5 (IS+EPCs/LICA administration post-day-7 IS), group 6 (IS+EPCs/LICA administration post-day-14 IS), and group 7 (IS+EPCs/LICA administration post-day-28 IS).

Internal carotid and vertebral arteries diameters and their interrelationships to sex and left/right side.

Folia Morphol (Warsz) 2020 1;79(2):219-225. Epub 2019 Jul 1.

Informatic in Medicine, Faculty of Medicine, University of Banja Luka, Save Mrkalja 14, 78000 Banja Luka, Bosnia and Herzegovina.

Background: The available anatomical data about diameters of inflow vessels to the circle of Willis reflect various diagnostic and imaging methods used, sample sizes, levels of measurements, and lack of possible specific ethnic, regional or genetic data. Additionally, the data are often without distinctions about left-right or sex.

Materials And Methods: Therefore, using computed tomography angiography (CTA) we investigated diameters of internal carotid (ICA) and vertebral (VA) arteries in 70 adult persons (28-75 years) of both sexes (34 males and 36 females), at predefined cervical parts of ICA (2 cm above carotid bifurcation) and of VA (5 mm before VA penetrated the dura).

Fast cerebral flow territory mapping using vessel encoded dynamic arterial spin labeling (VE-DASL).

Magn Reson Med 2016 May 22;75(5):2041-9. Epub 2015 Jun 22.

Department of Radiology, C. J. Gorter Center for high field MRI, Leiden University Medical Center, Leiden, The Netherlands.

Purpose: Whole-brain territory mapping using planning-free vessel-encoded pseudocontinuous arterial-spin-labeling (VE-pCASL) takes approximately 5 min, which is frequently considered too long for standard clinical protocols. In this study, vessel-encoded dynamic-ASL (VE-DASL) is optimized to achieve fast (< 30 s) cerebral flow territory mapping, especially aimed for the acute setting.

Methods: VE-DASL is based on the creation of a continuous stream of magnetically labeled or unlabeled blood with different encoding patterns for each feeding artery, whose inflow into the brain tissue is monitored continuously. Read More

Carotid artery stenting in patients with left ICA stenosis and bovine aortic arch: a single-center experience in 60 consecutive patients treated via the right radial or brachial approach.

J Endovasc Ther 2014 Feb;21(1):127-36

1 Department of Clinical Sciences and Community Health, University of Milan, Centro Cardiologico Monzino, IRCCS, Milan, Italy.

Purpose: To assess the safety and efficacy of carotid artery stenting (CAS) of the left internal carotid artery (LICA) from a right radial/brachial approach in patients with bovine aortic arch.

Methods: Among 505 consecutive CAS patients treated at our facility between June 2007 and December 2012, 60 (11.9%) patients (44 men; mean age 73±9 years) with LICA stenosis and bovine arch were treated from a right radial (n=32) or brachial (n=28) approach. Read More

Sonographic characteristics of carotid artery plaques: Implications for follow-up planning?

J Ultrasound 2012 Sep 23;15(3):151-7. Epub 2012 Jun 23.

Specialist Outpatient Clinic for Clinical and Vascular Sonography, Bolzano Healh District, Bolzano, Italy.

Unlabelled: The aim of our study was to analyze the ultrasound characteristics of carotid plaques in an outpatient population and to determine their implications for planning the ultrasound follow-up.

Materials And Methods: We studied 747 consecutive outpatients (397 [53%] of whom were women) who underwent color Doppler sonography of the carotid arteries. Most of the patients presented multiple cardiovascular risk factors or were being followed-up for carotid artery stenosis. Read More

The cerebral vasomotor response in varying CO(2) concentrations, as evaluated using cine phase contrast MRI: Flow, volume, and cerebrovascular resistance indices.

Med Phys 2012 Nov;39(11):6534-41

Department of Automatic Control Engineering, Feng Chia University, Taichung, Taiwan, Republic of China.

Purpose: Previous studies have identified that impaired cerebral vasomotor reactivity (VMR) is associated with a higher risk of stroke and transient ischemic attack. This study aims to evaluate VMR by measuring the blood flow waveforms of the supplying arteries and dural sinuses using cine phase contrast MRI (PC MRI) and hypercapnic challenge.

Methods: PC MRI flow quantification was performed on an oblique slice approximately perpendicular to the target vessels to include the left (LICA) and right internal carotid artery (RICA), basilar artery (BA), sinus rectus (SR), and superior sagittal sinus (SSS). Read More

Cardiovascular Department, S. Donato Hospital, Arezzo, Italy.

Purpose: To investigate the efficacy and safety of a tailored approach to fit access and engagement techniques to the individual arch anatomy in patients with bovine-type aortic arch (BTAA) to overcome the perceived increased risk of technical failure and cerebral embolization during left internal carotid artery (LICA) stenting.

Methods: Thirty-five high surgical risk patients (23 men; mean age 68.6 years, range 62-90) with BTAA and LICA stenosis underwent carotid artery stenting (CAS). Read More

Ultrasonic assessment of cerebral blood flow changes during ischemia-reperfusion in 7-day-old rats.

Ultrasound Med Biol 2008 Jun 20;34(6):913-22. Epub 2008 Feb 20.

AP-HP, Hôpital Lariboisière, Physiologie-Explorations Fonctionnelles, Université Denis Diderot Paris 7, Paris, France.

A model of ischemic brain injury in 7-day-old rat pups has been developed to study perinatal ischemia. It combines permanent occlusion of the distal left middle cerebral artery (LMCA) and transient occlusion of homolateral common carotid artery (LCCA). At removal of the clip on LCCA, reflow allowed brain reperfusion through cortical anastomoses. Read More

Quantitative contrast media dose evaluation for cranial computed tomography.

Comput Med Imaging Graph 1995 May-Jun;19(3):287-93

Division of Neuroradiology, Southern Illinois University School of Medicine, Springfield 62769, USA.

The goal of this study was to quantitatively evaluate the CT enhancement characteristics of selected intracranial blood vessels using four different volumes of a contrast medium under otherwise identical conditions in order to help determine a cost-effective dose. In a double blind, prospective manner, 100 patients referred for contrast-enhanced cranial CT were randomly assigned to receive one of four different volumes (50, 75, 100 or 120 ml) of ioversol 320 mg I/ml which was subsequently administered intravenously at a rate of 1 ml/s via a power injector. Unenhanced images were also obtained. Read More

[Application of mouse tail artery for the study of alpha adrenoceptor agonists and antagonists and calcium antagonists].

Yao Xue Xue Bao 1990 ;25(3):223-6

Institute of Materia Me lica, Chinese Academy of Medical Sciences, Beijing.

Isolated mouse tail artery strip was used for the study of alpha 1-, alpha 2-adrenoceptor agonists and antagonists. NA (alpha 1 and alpha 2 agonist) was shown to have greater activity in contracting tail artery. Phenylephrine (alpha 1 agonist) and clonidine (alpha 2 agonist) exhibited the same contractile action but much weaker than NA. Read More
