Background: Vascular and muscle deterioration are age-related processes, which both have a major impact on health and might share common predisposing factors and mechanisms. We investigated the possible association between aortic stiffness and physical performance in older outpatients. Methods: Aortic...

The vascular system is subject to continual variation in mechanical stresses, both physiological and pathological. Vascular remodeling via changes in vessel wall properties, including thickness and stiffness, is a major feature of aging and cardiovascular disease. A more detailed understanding of the...

It is shown that the normal distribution with mean zero is characterized by the property that the product of its characteristic function and moment generating function is equal to 1.

n this paper, we shall firstly illustrate why we should discuss the Aumann type set-valued Lebesgue integral of a set-valued stochastic process with respect to time t under the condition that the set-valued stochastic process takes nonempty compact subset of d -dimensional Euclidean space. After recalling...

Some predictive ratio type estimators in two stage sampling are derived following the model free predictive criterion proposed by Basu (1971) and these estimators are compared with the classical multistage ratio estimator and also with Smith’s (1969) multistage ratio estimator. A numerical illustration...

Background: Abdominal aortic aneurysm (AAA) disease is mainly treated by endovascular aneurysm repair (EVAR), which shows short-term advantages in terms of lower morbidity and mortality compared to open repair. Long-term outcome seems te be inferior with regard to survival. This could partly be explained...

There are few data regarding the effect of aging on pressure asymptote (Pasymptote) and time constant (Tau) of exponential diastolic aortic pressure (AoP) decay in normal human heart.

Background: The interaction between the heart and arteries (i.e. ventricular-arterial coupling, VAC) is a key determinant of cardiovascular performance. As such, VAC indexes might reflect the interplay between arterial stiffness and left ventricular (LV) dysfunction. In a community-based sample, we assessed...

Background: Caffeine, the most widely used pharmacologically active substance causes mental stimulation and a slight raising of blood pressure. The aim of our work was to evaluate the effect of caffeine on the cardiovascular system during rest and during mental stress. Methods: RR interval duration,...

Background: This study evaluated the test-retest reliability of carotid-femoral pulse wave velocity (PWV) and cardio-ankle vascular index (CAVI) among young adults in Jamaica. Methods: We recruited participants from the Jamaica 1986 Birth Cohort Study. PWV was measured using the Arteriograph device™...

According to “Technical Criterion for Ecosystem Status Evaluation” issued by State Environmental Protection Administration, on the basis of Arcgis platform, using the comprehensive evaluation index method, the paper takes Dongsheng district as a case, selected biological richness index, vegetation coverage...

Legendre transformations provide a natural symmetry on the space of solutions to the WDVV equations, and more specifically, between different Frobenius manifolds. In this paper a twisted Legendre transformation is constructed between solutions which define the corresponding dual Frobenius manifolds....
