Magnetic Resonance Assessment of Aortic Stiffness in Diabetes and Cardiovascular Disease
… from measurements such as pulse wave velocity (PWV). Aortic PWV can be estimated from the carotid and femoral sites (CFPWV) by applanation tonometry and ultrasound. However, these methods only estimate a gross global burden, which may mitigate regional stiffness within the vasculature, and can …

Determination of the suitability of MT Gamsberg in Namibia for millimetre wave stronomy by measurements of the precipitable water vapour
Precipitable Water Vapour (PWV) is the amount of water vapour in the atmospheric column above a location equivalent to the amount of liquid precipitation that would result if all the water vapour in the column was condensed. Water vapour is the main source of opacity in the Earth’s atmosphere at …

ACUTE EFFECTS OF LONG DISTANCE RUNNING ON C-REACTIVE PROTEIN AND ARTERIAL STIFFNESS
… stiffness, indicated by pulse wave velocity (PWV), is increased during the hour post ultramarathon (ULT), but it's currently unknown if PWV remains elevated 24 hours after ULT or marathon (MAR). <strong>PURPOSE: </strong>To determine the effects of ULT and MAR on C-reactive protein (CRP), …

The effects of an acute bout of traditional versus circuit resistance exercise on arterial stiffness and blood pressure
… on separate days. Pulse wave velocity (PWV) was used as a measure of central and peripheral arterial stiffness at baseline, at 15 minutes post, and at 30 minutes post exercise. Central PWV increased in the CREP mode and returned toward baseline at 30 minutes post-exercise (p<0.05). …

The estimation of precipitable water vapour from GPS measurements in South Africa
… the amount of precipitable water vapour (PWV) in the atmosphere. The application of the GPS data for the estimation of PWV in the atmosphere is not a new concept and has been described in numerous publications and reports since the early 1990's (Bevis et al., 1992, Rocken et al., 1993). …

The effects of an acute bout of whole-body vibration on pulse wave velocity in individuals with SCI
… compliance as measured by pulse wave velocity (PWV). On separate days, arm, leg and aortic PWV were measured pre- and post- a 45 minute session of passive stance (PS) and WBV. The WBV was intermittent with a set frequency of 45Hz and amplitude of O.6mm. There was no condition by time effect when …

The role of pulmonary arterial stiffness in right ventricular remodelling in COPD
… undertaken to test the hypothesis that pulmonary PWV would be elevated in COPD, and that this would correlate with right ventricular mass, and predict future adverse remodeling.<br/><br/>Two commonly used techniques are available for measuring PWV with MRI: the transit time technique and the …

Association of Aortic Vascular Stiffness with Epicardial and Pericardial Adipose Tissues on 64-Multidetector Computed Tomography : In Relation with Coronary Atherosclerosis
… and their carotid-radial pulse wave velocity (PWV) was measured using SphygmoCor tonometry. EAT and total thoracic adipose tissue (TAT) volumes were measured using MDCT. PAT was calculated as TAT – EAT. The highest tertile of EAT (≥ 111 ml) and PAT (≥ 103 ml) were defined as significant adipose …

Effects of smoking on arterial stiffness and haemodynamics in male adolescents in Lusaka
… blood pressure. Increase in Pulse Wave Velocity (PWV), suggesting an increased arterial stiffness has been demonstrated in white smokers. An increase in plasma catecholamines and an impaired Nitric Oxide production are the likely cause of the endothelial dysfunction. The aim of this study was to …

Osteoporosi e biomarcatori precoci di danno vascolare.
… carotideo (IMT) e della Pulse Wave Velocity (PWV), confrontando tali risultati con quelli di una popolazione sana di controllo. Sono stati arruolati 58 pazienti con osteoporosi e un pari numero di soggetti sani di controllo. Tutti i soggetti sono stati sottoposti ad esame densitometrico osseo …

The Relationship of Physical Activity and Fruit and Vegetable Intake on Pulse Wave Velocity
… using carotid-femoral pulse wave velocity (PWV). While supine, a cuff was placed around the right thigh and inflated. Concurrently, a tonometer was placed over the carotid artery and data were obtained from both carotid and femoral waveforms after 10 consecutive seconds. Results: …

Sensing atmospheric water vapour using the global positioning system
… and geodesists. Precipitable water vapour (PWV) is a greenhouse gas to be reckoned with in numerical weather models and climate change studies, it is a nuisance in centimetre-wavelength radio astronomy and introduces range errors in space geodetic techniques. The propagation time of …

Does smoking impact on the association between oxidative stress and vascular function in young normotensives? the African-Predict study
… also been shown to increase pulse wave velocity (PWV). Higher levels of antioxidant enzymes such as glutathione peroxidase-3 (GPx-3) is associated with wider central retinal artery equivalent (CRAE). Cigarette smoke is associated with increased PWV and decreased compliance, suggesting an increase …

Arterial Destiffening with Weight Loss in Overweight and Obese Middle-Aged and Older Adults
… carotid-femoral artery pulse wave velocity (C-F PWV), and with high-resolution ultrasonography of the carotid artery (β-SI). There were no baseline differences between groups in our variables of interest. Consistent with our hypothesis, both measures of AS were significantly reduced (C-F PWV= …

Large Artery Stiffness: Genes and Pathways
… that had undergone ex vivo pulse wave velocity (PWV) phenotyping. The first part of this work sought to investigate the molecular basis of Loeys-Dietz type 4 syn- drome in a pedigree with multiple cases of aortic aneurysms and dissections. A missense variant p.(Arg320Cys) was identified in a …

A Novel Method to Assess Pulse Wave Velocity using Single Velocity Encoding in Phase Contrast Imaging
The measurement of pulse wave velocity (PWV) using conventional phase contrast magnetic resonance imaging (PC-MRI) is recognized as a standard technique to assess arterial stiffness by measuring the arrival times of blood velocity waveforms. Conventional PC-MRI requires the acquisition of two sets …
