Background. The anticontractile effect of perivascular adipose tissue(PVAT) is lost in obese patients due to adipocyte hypertrophy, leading to hypoxia, inflammation, and oxidative stress(Circulation 2009; 119(12):1661–1670).We recently demonstrated that the property of PVAT, partially maintained in an...

Objective. Pressure wave reflection poses a load on the heart often augmenting pressure and adversely affecting cardiac output. Reflection effects are age dependent and may be altered by sympathetic activation by postural stress. We sought to determine the influence of standing on wave reflection and...

Background. Inflammatory bowel disease (IBD) is associated with an increased cardiovascular risk that is not explained by traditional cardiovascular risk factors, as well as an increased arterial stiffness. In this study, we investigated the relationship between inflammation and arterial stiffening and...

Background: prolonged circulatory unloading associated with head-down tilt bed rest (HDTBR) is followed by cardiovascular deconditioning. Aim of the study was to investigate to what extent large artery function and arterial-ventricular coupling (VA) are involved. Methods: ten healthy male volunteers...

Cardiovascular fibrosis is a hallmark of aging. We had previously demonstrated, that a steroidal endogenous Na/K-ATPase inhibitor, marinobufagenin (MBG), plays a central role in cardiac fibrosis occurring in the context of experimental uremic cardiomyopathy (Hypertension 2007;49:215–24) via participation...

Different from other natural disasters and health emergencies, nuclear accident is a kind of special crisis of organizational crises, which tends to generate public and media interests and criticism more easily. In this paper, we reviewed literatures on risk and crisis communication and analyzed the...

In this paper, the researchers attempt to introduce a new generalization of the exponential distribution. This new model is obtained by compounding the exponential distribution and discrete generalized exponential distribution of a second type, which is a generalization of the geometric distribution....

This paper focuses on stability control for the levitated positioning of the magnetic levitation vehicle system. For the nonlinear magnetic levitation system model, the output feedback linearization method is employed to derive a global linearization error model. However, there exists uncertain item...

In this paper, the Weibull-X family is proposed and some of its properties are discussed. A member of the Weibull-X family, the Weibull-logistic distribution, is defined and studied. Various properties of the Weibulllogistic distribution are obtained. The distribution is found to be unimodal and the...

It is shown that the 2-discrete dimensional Lotka-Volterra lattice, the two dmensional Toda lattice equation and the recent 2-discrete dimensional Toda lattice equation of Santini et al can be obtained from a 2-discrete 2-continuous dimensional Lotka-Volterra lattice.

The discrete group generated by reflections of the sphere, or the Euclidean space, or hyperbolic space are said to be Coxeter groups of, respectively, spherical, or Euclidean, or hyperbolic type. The hyperbolic Coxeter groups are said to be (quasi-)Lannér if the tiles covering the space are of finite...

Introduction: Over 80% of cardiovascular deaths take place in low- and middle-income countries; most of these deaths are due to modifiable risk factors. The study aimed at estimating the prevalence and pattern of major cardiovascular risk factors in both men and women older than 18 years. Methods: This...

Programs in the event-driven style that are typical of mobile and/or Web applications are becoming complex and hard to maintain. For the purpose of reducing the burden put on software developers while reading source code to understand its details, we propose a tool for supporting program understanding,...

This paper presents a new spherical mobile robot driven by single omni wheel. The physical model is that an arc track is built inside the sphere shell and can rotate around a spherical diameter freely. It supports one driving omni wheel and keeps the driving omni wheel touching the inside of the sphere...

In this paper, the problem of measuring the degree of subsethood in the interval-valued fuzzy setting is addressed. Taking into account the widths of the intervals, two types of interval subsethood measures are proposed. Additionally, their relation and main properties are studied. These developments...

The satisfaction of the patients and its importance in modern medicine cannot be emphasized enough. It is a potential tool that can invariably give a look-in into the performance of a hospital itself and health professionals (either directly or indirectly). The purpose of this study was to evaluate patient...

We present a method devised by Jacobi to derive Lagrangians of any second-order differential equation: it consists in finding a Jacobi Last Multiplier. We illustrate the easiness and the power of Jacobi's method by applying it to several equations, including a class of equations recently studied...

We present a 3×3 Riemann-Hilbert problem formalism for the initial-boundary value problem of the two-component nonlinear Schrödinger (2-NLS) equation on the half-line. And we also get the Dirichlet to Neuemann map through analysising the global relation in this paper.

Role and function of the Carotid Intima Media Thickness (CIMT) and atherosclerotic Plaque (P) in clinical management of cardiovascular risk factors is yet unclear. Cardiovascular Risk Factor Stratification (SCORE) and CIMT with P typing and visualization were assessed in 269 asymptomatic individuals...

Background. Organic nitrates (e.g. nitroglycerin) are highly selective dilators of muscular conduit arteries. By contrast, the endogenous inorganic nitrite anion (NO2−) is thought to be a hypoxia-dependent dilator of small resistance arterioles, via its reduction to vasodilating nitric oxide (NO) by...

Objectives: Anatomical and physiological data on the forearm venous vascular bed is needed to (i) gain insight into the complex arterial and venous remodeling processes after creation of an arterio-venous fistula, and (ii) provide input data for computer models of the forearm vasculature. Methods: Ultrasound...

Background. No prospective study has examined whether markers of the central hemodynamics, e.g., central pulse pressure, might be a more robust marker of change in the cardiac hemodynamic load, estimated by the change during the study period of the serum levels of N-terminal fragment B-type natriuretic...

Although the viscoelasticity of large arteries has been extensively investigated, few studies have focused on arterial wall viscosity (AWV) itself and its regulation by the endothelium in vivo. This is of particular importance since AWV is a major source of energy dissipation through the vascular system...

Background. Carotid endarterectomy (CEA) is widely recognised as an effective surgical method in both symptomatic and asymptomatic patients with significant internal carotid artery stenosis. Although the association between vulnerable carotid plaques and stroke is well established, little is known about...

Objective: To examine the influence of calibration of peripheral blood pressure on the estimation of central systolic blood pressure (cSBP) from peripheral arterial waveforms using a transfer function. Methods: Central aortic pressure was measured with a pressure tipped catheter (Millar, Houston, Texas)...

Background. Pulse wave analysis (PWA) using cuff based methods emerged within the last years. Compared to traditional sensors used in PWA like catheters and piezo gauges very little is known on the frequency response of cuff based systems according to standard measurement and systems theory. Therefore...

This paper shows a tool for EPN (Extended Place/transition Net)-based mutation testing to evaluate and improve the quality of a test suite for concurrent software. The tool includes functions for (1) construction of an original EPN that represents the expected behavior of concurrent software under test,...
