Background: In chronic kidney disease (CKD), anomalies of mineral bone disorder (MBD) play a central role in vascular calcification and increased aortic stiffness. The impact of antihypertensive drugs on MBD-induced vascular calcification remains uncertain. The aim of this study was to examine whether...

Background: Arterial stiffening is an important predictor of cardiovascular risk. In order to identify the pathogenic mechanisms it is necessary to characterise arterial micro-structure and –mechanical properties. Here, we test the hypothesis that chemical fixation (employed in microscopical preparation...

Background: Aortic Pulse Wave Velocity (Ao-PWV) predicts cardiovascular disease and renal dysfunction in Type 2 Diabetes (T2DM). Klotho is a circulating anti-ageing hormone that has direct cardio-renal protective effects in animal studies. We have previously demonstrated that circulating levels of Klotho...

Technological developments made it possible to detect a longitudinal motion of the arterial wall. Our previously presented method can estimate this motion with high accuracy, but the method requires ultrasound images of very high quality. The aim of this study was to evaluate a novel method for estimating...

This paper describes the first Artificial Bee Colony (ABC) Algorithm approach applied to nurse scheduling evaluated under different working environments. For this purpose, the model has been applied on a real hospital where data taken from different departments of the hospital were used and the schedules...

We analyze the relation of the notion of a pluri-Lagrangian system, which recently emerged in the theory of integrable systems, to the classical notion of variational symmetry, due to E. Noether. We treat classical mechanical systems and show that, for any Lagrangian system with m commuting variational...

Baby Boomers (BBs) are responsible for three-quarters of hepatitis C virus (HCV) infections in the United States; however, HCV testing is distinctly underused by them. A cross-sectional study was conducted to assess the prevalence of HCV testing and to evaluate predictors of HCV testing intention among...

The issues raised by noncommunicable diseases (NCDs) during and after disasters are a challenge to equity within local communities, as well as between countries. Individuals with NCDs are particularly vulnerable in disasters and their aftermath given health systems are disrupted. Although welcome progress...

Blood pressure variability (BPV) is defined by the standard deviation of a given sample of population of normotensive or hypertensive subjects. Recent studies have suggested that this parameter might constitute a cardiovascular risk factor. Reduction of blood pressure variability could be an important...

Laccase is a Class 1 oxidoreductase enzyme, which catalyzes the oxidation of a wide range of phenolic substrates. Previously, several reviews had highlighted on the industrial importance of laccase, including in food industry. Similarly, the ability of laccase to crosslink and polymerize food protein...

Although by the end of 2020, most of companies will be running 1000 node Hadoop in the system, the Hadoop implementation is still accompanied by many challenges like security, fault tolerance, flexibility. Hadoop is a software paradigm that handles big data, and it has a distributed file systems so-called...

During the COVID-19 pandemic, it was rapidly established that cancer patients have an increased risk of developing severe forms of the 2019 coronavirus disease (COVID-19) due to a backlog of cancer diagnostics and immunosuppressive treatments. Cancer centers had to quickly adapt to continue cancer therapies...

Using the Inverse Scattering Method with a nonvanishing boundary condition, we obtain an explicit breather solution with nonzero vacuum parameter b of the focusing modified Korteweg–de Vries (mKdV) equation. Moreover, taking the limiting case of zero frequency, we obtain a generalization of the double...

Background: Diabetes converts from a metabolic disorder into a predominantly vascular disease, once its duration extends over several years or/and when additional cardiovascular risk factors such as hypertension coexist. We analyzed various vascular parameters in the renal, retinal and systemic circulation,...

Objectives: Assessment of pulse wave velocity (PWV) is normally used as a measure of arterial stiffness. However, measurement of change in PWV before and after a period of reactive hyperaemia may enable the technique to be harnessed as a measure of endothelial function as flow-mediated slowing (FMS)....

Background: The relation between telomere dynamics and obesity remains unclear. Cross-sectional studies found associations between short leukocyte telomere length (LTL) and high body mass index (BMI) but longitudinal studies did not find any association between LTL attrition and BMI. In two parallel...

Objectives: Determination of the cross-sectional mechanical properties of artery is crucial for correlating regional arterial stiffness with the biological components such as collagen, elastin, and deposited calcium. While ultrasound imaging has been used to determine these properties from the arterial...

Background: Relatively little is known about equine arterial hemodynamics because it is technically and ethically challenging to investigate a large number of arteries. Pulsed-wave Doppler images of arterial flow velocities typically display patterns of a higher oscillatory nature than in humans, but...

Objectives: Carotid artery stiffness has been suggested to alter local haemodynamic and arterial remodelling. It has also been shown to be associated with ischaemic stroke. The aim of this pilot study is to assess the feasibility of measuring carotid pulse wave velocity (cPWV) using magnetic resonance...

As the growth of network technology with high parallelism and high reliability of distributed systems, they have been widely adopted in the enterprise and society. But, how to design for testing the real-time or a communication delay of distributed systems is not been discussed much. This paper proposes...

In ad hoc networks, due to the mobility of nodes, communication links are unstable and restricted. As such, an efficient routing protocol is needed in order to solve these problems. In the present paper, we propose a neighbors based routing (NBR) protocol by constructing paths in an area in which a large...

Vulnerability of urban receptors in flood prevention is rising during the rapid urbanization, and emergency response strategies were introduced to strengthen the capacity of urban flood prevention and flood disaster response. Emergency plan for flood control, which is considered as one of the most important...

Following V. Drinfeld and G. Olshansky, we construct Manin triples (g, a, a ) such that g is different from Drinfeld's doubles of a for several series of Lie superalgebras a which have no even invariant bilinear form (periplectic, Poisson and contact) and for a remarkable exception. Straightforward superization...
