Background: Effects of short-term interventions on large artery stiffness assessed by pulse wave velocity (PWV) have mainly been explained by concomitant changes in blood pressure (BP). However, lower body negative pressure (LBNP), which increases sympathetic activity (SA) has a specific effect on PWV...

Case retrieval is a crucial step in case-based reasoning (CBR), which is related to decision-making effectiveness. To improve decision support, CBR usually calculates case similarity and evaluates utility. However, the psychological behavior of decision makers is seldom considered in case retrieval....

Introduction: It has been long debated whether Arteriograph predicts cardiovascular events and/or all cause mortality, despite that its prognostic value has been proven in systolic heart failure and in myocardial infarction already. However, no data were available about the prognostic value of this method...

Identification and characterization of gene regulatory binding motifs is one of the fundamental tasks toward systematically understanding the molecular mechanisms of transcriptional regulation. Recently, the problem has been abstracted as the challenge planted (l,d)-motif problem. Previous studies have...

Objective: Pulse pressure amplification (PPA) is described as the amplification of pulse pressure from central arteries to the periphery [1] and individuals with a decreased PPA have an increased risk of cardiovascular disease [2]. Adverse changes in PPA are evident in diabetic populations [3]; however,...

Cerebral pulsatility is an emerging contributor to brain health that reflects the balance between the transmission and damping (i.e. attenuation) of pulsatility through extracranial vessels into the cerebrovasculature. Identifying biological (age, sex) and vascular contributors to pulsatile balance may...

Background: Low-flow-Mediated Constriction (LFMC) is considered as a measure of resting endothelial function and is believed to occur in response to reduction in flow during supra-systolic occlusion [1]. However, supra-systolic occlusion may alter flow profile with differential effects on anterograde...

Background: The range of central blood pressure (BP) found in individuals with high-normal brachial BP overlaps the one found in hypertension (HTN) and normotension. As central BP is possibly a better predictor of cardiovascular (CV) disease, the aim of this study was to determine the risk associated...

Background: Literature describes differences in Low flow mediated constriction (LFMC) of radial versus brachial artery [1,2]. We investigated whether differences in occlusion induced changes in luminal flow and shear rates could explain the observed radial vs brachial differences in LFMC responses. Methods:...

Recently, many promising indices of micro- and macrocirculation have been widely used to promptly detect target organ damage before major cardiovascular events occur. More specifically, nailfold capillaroscopy, fundoscopy, near-infrared spectroscopy, ultrasound, laser speckle contrast analysis and central...

The objective of this study was to evaluate the impact of the tuberculosis (TB) mobile teams on treatment outcomes in Riyadh Region by comparing patients who received treatment under mobile teams and those who did not, from 2013 to 2015. This was a retrospective descriptive study using National TB Control...

Background: Exaggerated exercise systolic blood pressure (SBP) is a modifiable risk factor associated with vascular dysfunction. Vascular dysfunction may contribute to the development of late-life depression, but the association between exercise SBP and incident depressive symptoms is unknown. Therefore,...

Background: Dysfunctional cellular mechanosensing appears central to aneurysm formation [1]. We aimed to derive material parameters of aneurysm tissue from in vivo deformations, which may increase insight into the underlying structural integrity of the pathological tissue. Methods: Videos of tracking...

Objective: Exaggerated exercise blood pressure (BP) is associated with cardiovascular risk factors in adolescence. Aerobic fitness and adiposity (fat mass or ‘fatness’) are important independent contributors to cardiovascular risk in adolescence, but their interrelated associations with exercise BP are...

This paper presents a new correlation coefficient measure, which satisfies the requirement of this measure equaling one if and only if two interval neutrosophic sets (INSs) are the same. And an objective weight of INSs is presented to unearth and utilize deeper information that is uncertain. Using the...

Improving maternal health is one of the goals to be achieved under the Millennium Development Goal (MDG), especially MDG-5. One of the predictors of maternal health is place of child birth. This study was carried out to determine the prevalence of home delivery and different socio-demographic factors...

Introduction: Microgravity in space is known to cause major alterations in the cardiovascular system. Left ventricular ejection time (LVET) can be measured by the time from the onset point of the pressure wave to the incisura of the dicrotic notch. The aim of this study was to simulate microgravity by...

Currently, recommender systems (RS) are incorporating implicit information from social circle of the Internet. The implicit social information in human mind is not easy to reflect in appropriate decision making techniques. This paper consists of 2 contributions. First, we develop an item-based prototype...

Over the years, there has been an evolution in the manner in which we perform traditional tasks. Nowadays, almost every simple action that we can think about involves the connection among two or more devices. It is desirable to have a high quality connection among devices, by using electronic or optical...
