Objectives: We sought to investigate whether reverse dipping status is associated with self-reported health-related quality of life (HRQOL). Methods: BP was evaluated non-invasively under 24-hour ABPM with a brachial cuff-based automatic oscillometric device (Mobilo-O-Graph, IEM); all subjects maintained...

Introduction: Intra-aortic balloon pumping is widely used to augment diastolic coronary perfusion. However, far less is known about its effects on other large arteries. In this study we assessed the effects of intra-arterial balloon pump pressure support on pressure and flow in the proximal aorta, carotid,...

Objects: Waon-Therapy was invented for the therapy of heart failure by Dr. Tei. The purpose of this study was to confirm the efficacy of Waon therapy and to clarify the role of Waon-therapy in the arterial stiffness monitoring with cardio-ankle vascular index (CAVI). Subjects and methods: Study 1 Subjects...

Background: Patients with rheumatoid arthritis (RA) have increased cardiovascular morbidity and mortality. Objective: To explore whether early markers of RA inflammatory disease activity could predict later cardiovascular disease and arterial stiffness, and to describe the impact of later use of disease-modifying...

Introduction: The increased risk of stroke following a Transient Ischaemic Attack (TIA) is well established. Central aortic pressure, a marker of arterial stiffness, is emerging as a predictor of cardiovascular events including stroke. Additionally brachial Blood Pressure (BP) measurements may not accurately...

The kernel approach has been applied using the adaptive kernel density estimation, to inference on the generalized gamma distribution parameters, based on the generalized order statistics (GOS). For measuring the performance of this approach comparing to the Asymptotic Maximum likelihood estimation,...

Web services bring more conveniences for users and developers. However, it makes user face the problem of service information explosion. The personalized service recommendation solves the problem. This paper proposes a mechanism to evaluate Web service composition’s reliability which bases on user context...

Emergency management agencies will organize people to evacuee when disasters are forecasted. However, contradictions between individual behavior and group objective appear frequently during large-scale evacuations, the problem is obviously in the process of fisher boats evacuation. So, this paper set...

A model for simulating the output signals of Hall sensors installed with misalignment in a brushless DC (BLDC) motor is proposed in this paper. In the past, Hall sensors have been very widely adopted to evaluate the commutation timing and rotation speed of a BLDC motor. However, no simulation model is...

It is known that many integrable systems can be reduced from self-dual Yang-Mills equations. The formal solution space to the self-dual Yang-Mills equations is given by the so called ADHM construction, in which the solution space are graded by vector spaces with dimensionality concerning topological...

The problem of studying the maximal Lie symmetry of some nonlinear generalization of the vector subsystem of the Maxwell equations is completely solved.

The singular manifold expansion of Weiss, Tabor and Carnevale [1] has been successfully applied to integrable ordinary and partial differential equations. They yield information such as Lax pairs, Bäcklund transformations, symmetries, recursion operators, pole dynamics, and special solutions. On the...

We classify the Noether point symmetries of a generalized Lane-Emden equation. We obtain first integrals of the various cases which admit Noether point symmetry and find reduction to quadratures for these cases. Three new cases are found for the function f (y). One of them is f (y) = ?y r, where r

The analytical solutions of a nonlinear fin problem with variable thermal conductivity and heat transfer coefficients are investigated by considering theory of Lie groups and its relations with λ-symmetries and Prelle-Singer procedure. Additionally, the classification problem with respect to different...

The world stunned by a pandemic of such cataclysmic scale is reeling under the joint burden of health impact unleashed by the diseases and the strain on the economy. Glaring shortfalls and inconsistencies in strategies to combat the pandemic have surfaced worldwide irrespective of the country’s economic...

A reciprocal transformation is introduced for a three-component Camassa-Holm type equation and it is showed that the transformed system is a reduction of the first negative flow in a generalized MKdV hierarchy.

Background: Migraine is associated with an increased risk for ischemic stroke and other cardiovascular (CV) events, including angina, myocardial infarction, and CV death. However, the mechanisms which link migraine to CV disease remain uncertain. In the present case-control study, we hypothesized that...

Objectives: To examine the role of physical activity in vascular stiffness and markers of adiposity and inflammation in “healthy” subjects. Methods: Seventy-nine (51 male & 28 female) healthy subjects were recruited. All were lifelong non-smokers, normotensive, normolipidaemic and normoglycaemic....

Introduction: Risk of a cardiovascular event is known to increase in the period immediately post-transplantation before returning to baseline or lower. We hypothesised that this might be due to changes in arterial stiffness and/or endothelial function. Methods: We measured aortic pulse wave velocity...

Objectives: Music has been correlated to cardiovascular health and used as additional therapy in patients with cardiovascular disease, however, few are known on the impact of music on arterial stiffness and central hemodynamics which are both predictors of cardiovascular risk. We investigated the effect...

Background: Arterial calcification is commonly observed in cardiovascular disease and is associated with increased arterial stiffness, systolic hypertension and adverse cardiovascular outcome. Arterial calcification is an actively regulated process with several stimulating and inhibiting factors. An...

Objective: Polycystic ovary syndrome (PCOS) is characterised by obesity and a high prevalence of insulin resistance (IR) but this may not translate into increased cardiovascular events. The energy and timing of waves in large arteries may be quantified by separated wave analysis from wave intensity (WI)...

Introduction: Aortic stiffness is related to renal function in patients with chronic kidney disease and may contribute to the high cardiovascular mortality in this group. However, the relationship between renal function and arterial haemodynamics in the general population has not previously been reported. Methods:...
