Aims: To compare central systolic blood pressure (cSBP) and augmentation index (AIx) from 2 recently introduced devices Omron-HEM9000 (OM) and Arteriograph (AG) not using a transfer function with that of the widely used SphygmoCor (SC), which together with another radial device OM is calibrated on brachial...

Background: Abdominal aortic calcification (AAC) is an independent determinant of cardiovascular events. Computed tomography (CT) is currently the gold standard for measuring aortic calcification but is limited by relatively high radiation exposure. Lateral dual-energy X-ray absorptiometry (lateral-DXA)...

Evaluating diastolic function in children remains a topic of clinical discussion and a gold standard measurement technique is still lacking. Wave intensity analysis can provide insight into ventricular filling mechanisms and ventriculo-vascular coupling, and it can be derived directly from cardiovascular...

Objective: Pulse wave velocity (PWV) is accepted as the standard technique to assess aortic stiffness. While the carotid-femoral transit time can be assessed with high accuracy, the measurement of the aortic length is, however, less accurate. Several approaches for measuring aortic length over the body-surface...

Objectives. To combine cardiovascular magnetic resonance (CMR), which provides accurate and non-invasive evaluation of flow, with applanation tonometry to assess aortic characteristic impedance (Zc) in time domain while comparing six different methods. Methods. We studied 72 healthy volunteers (31women,...

This paper explores the effect of geographical location on public risk perception of natural disasters. By conducting an identical questionnaire survey across three East Asia countries (China, Japan and South Korea), the paper finds out that different country has its unique structure of risk perception....

Based on the goodness of fit approach, a new test is presented for testing exponentiality against "exponential Better than Used in moment generating function ordering class" (EBUmgf). The critical values and the powers of this test are calculated. It is shown that the proposed test enjoys good power...

We introduce a nonlinear and noncanonical gauge transformation which allows the rduction of a complex nonlinearity, contained in a Schrödinger equation, into a real one. This Schrödinger equation describes a canonical system, whose kinetics is governed by a generalized Exclusion-Inclusion Principle....

We attempt to reconstruct the irreducible unitary representations of the Banach Lie group U0(H) of all unitary operators U on a separable Hilbert space H for which U - I is compact, originally found by Kirillov and Ol'shanskii, through constrained quantization of its coadjoint orbits. For this purpose...

A relativistic two-particle system with time-asymmetric scalar and vector interactions in the two-dimensional space-time is considered within the frame of the front form of dynamics using the dynamical symmetry approach. The mass-shell equation may be represented in terms of the nonlinear canonical realization...

We describe some recent results for a class of nonlinear hydrodynamical approximation models where the geometric approach gives insight into a variety of aspects. The main contribution concerns analytical results for Euler equations on the diffeomorphism group of the circle for which the inertia operator...

Objectives: To understand the acceptability of, and willingness to pay for, community health insurance coverage among residents of rural India. Methods: We conducted a mixed methods study of 33 respondents located in 8 villages in southern India. Interview domains focused on health-seeking behaviors...

The objective of this study was to examine the epidemiology and the clinical manifestations of typhoid fever as well as the susceptibility and strain relatedness of Salmonella typhi isolates in Lebanon from 2006 to 2007. A total of 120 patients with typhoid fever were initially identified from various...

Novikov super-algebras are related to quadratic conformal super-algebras which correspond to Hamiltonian pairs and play fundamental role in completely integrable systems. In this paper, we focus on quadratic Novikov super-algebras, which are Novikov super-algebras with associative non-degenerate super-symmetric...

Like some social animal groups, the evolution of plant populations in nature also contains swarm intelligence. Aiming at the problem of swarm Unmanned Aerial Vehicles (UAVs) target searching in complex and unknown environments, this paper explores search models suitable for swarm UAVs by investigating...

Background: The exact mechanism by which electrical carotid baroreceptor activation (CBA) lowers blood pressure in patients with hypertension has yet to be fully elucidated. Given the central role of the kidneys in blood pressure regulation, the aim of this study was to assess the impact of CBA on renal...

Background: Recently the pulse wave velocity (PWV) threshold of hypertensive target organ damage (TOD) was set at 10 m/s. New 24 – h monitors (e.g., BPLab-Vasotens) provide not only 1 PWV but several PWV measurements over a 24 – h period. The new Pulse Time Index of Norm (PTIN) can be calculated from...

Rationale: Alpha 1 Antitrypsin (AAT) deficiency is a familial cause of emphysema, due to reduced antiproteolytic activity within lungs. Systemic manifestations however, remain little explored. We have previously demonstrated increased arterial stiffness (AS) in patients with COPD and hypothesised that...

Introduction: Obesity is associated with increased cardiovascular morbidity and mortality. Arterial stiffness (AS) is an independent cardiovascular risk factor. The objective of this study was to evaluate the SA in obese patients. Patients and methods: AS was measured in 212 participants divided into...

Background: Hereditary amyloidosis are late-onset autosomal dominant disorders characterized by amyloid deposition in various tissues. Among them, Apolipoprotein A-I amyloidosis (Leu75Pro) is a rare autosomal dominant condition in which renal, hepatic, and testicular involvement has been demonstrated.No...
