Am J Physiol Heart Circ Physiol 2020 Jul 10. Epub 2020 Jul 10.

Health and Exercise Sciences, Bangor University, United Kingdom.

Changes in the arterial baroreflex arc contribute to elevated sympathetic outflow and altered reflex control of blood pressure with human ageing. Utilizing ultrasound and sympathetic microneurography (muscle sympathetic nerve activity; MSNA)we investigated the relationships between aortic and carotid artery wall tension (indices of baroreceptor activation) andthe vascular sympathetic baroreflex operating point (OP; MSNA burst incidence) in healthy, normotensive young (n = 27, 23 ± 3 years) and middle-aged men (n = 22, 55 ± 4 years).In young men, the OP was positively related to the magnitude and rate of unloading and time spent unloaded in the aortic artery (r = 0.

Motion synchronisation patterns of the carotid atheromatous plaque from B-mode ultrasound.

Sci Rep 2020 Jul 8;10(1):11221. Epub 2020 Jul 8.

Biomedical Simulations and Imaging Lab., School of Electrical and Computer Engineering, National Technical University of Athens, Athens, Greece.

Asynchronous movement of the carotid atheromatous plaque from B-mode ultrasound has been previously reported, and associated with higher risk of stroke, but not quantitatively estimated. Based on the hypothesis that asynchronous plaque motion is associated with vulnerable plaque, in this study, synchronisation patterns of different tissue areas were estimated using cross-correlations of displacement waveforms. In 135 plaques (77 subjects), plaque radial deformation was synchronised by approximately 50% with the arterial diameter, and the mean phase shift was 0. Read More

Neuroimage 2020 Jun 26;220:117095. Epub 2020 Jun 26.

Technical University of Munich, School of Medicine, Klinikum rechts der Isar, Department of Diagnostic and Interventional Neuroradiology, Munich, Germany; Technical University of Munich, School of Medicine, Klinikum rechts der Isar, TUM Neuroimaging Center, Munich, Germany; Technical University of Munich, School of Medicine, Klinikum rechts der Isar, Clinic for Neurology, Munich, Germany.

Magnetic resonance imaging (MRI)-based quantification of the blood-oxygenation-level-dependent (BOLD) effect allows oxygen extraction fraction (OEF) mapping. The multi-parametric quantitative BOLD (mq-BOLD) technique facilitates relative OEF (rOEF) measurements with whole brain coverage in clinically applicable scan times. Mq-BOLD requires three separate scans of cerebral blood volume and transverse relaxation rates measured by gradient-echo (1/T∗) and spin-echo (1/T). Read More

The influence of habitual endurance exercise on carotid artery strain and strain rate in young and middle-aged men.

Exp Physiol 2020 Jun 24. Epub 2020 Jun 24.

Cardiff School of Sport & Health Sciences, Cardiff Metropolitan University, Cardiff, UK.

New Findings: What is the central question of this study? Carotid artery peak circumferential strain (PCS) and strain rate attenuate with age, but appear to be modulated by cardiorespiratory fitness status in young males. However, the relationship between habitual endurance exercise (running) and these parameters has not been studied in young and middle-aged men. What is the main finding and its importance? Young and middle-aged runners exhibited elevated PCS and systolic strain rate (S-SR) compared with non-runners, but habitual running did not influence diastolic strain rate (D-SR). Read More

Carotid Stenosis Assessment with Vector Concentration before and after Stenting.

Diagnostics (Basel) 2020 Jun 20;10(6). Epub 2020 Jun 20.

Department of Radiology, Copenhagen University Hospital, Rigshospitalet, 2100 Copenhagen, Denmark.

Digital subtraction angiography (DSA) is considered the reference method for the assessment of carotid artery stenosis; however, the procedure is invasive and accompanied by ionizing radiation. Velocity estimation with duplex ultrasound (DUS) is widely used for carotid artery stenosis assessment since no radiation or intravenous contrast is required; however, the method is angle-dependent. Vector concentration (VC) is a parameter for flow complexity assessment derived from the angle independent ultrasound method vector flow imaging (VFI), and VC has shown to correlate strongly with stenosis degree.
