Introduction: Pulse wave velocity or (or VWV) may relate to muscle mass and body fat. We have included measurements for the above in the routine 12 channel ECG. Methods: A 12 channel ECG supplies impedance plethysmographic measurements at the four extremities at 40 kHz [1]. From these VWW was derived...

Objectives: Identification of factors associated with premature vascular aging in patients with arterial hypertension (AH). Methods: The study included 61 patients (29 men, 32 women) with 1–2 grade AH without cardiovascular complications, aged 40 to 60 years, of which 28 (45.9%) had type 2 diabetes....

Digital filters are generally designed by identifying the transfer functions. Most researches are focused on the goal of approaching the desired frequency response, and take less additional consideration of structure characteristics which can greatly affect the performance of the digital filter. This...

Fuzzy tensors encode to what extent n-ary predicates are satisfied. The disjunctive box cluster model is a regression model where sub-tensors are explanatory variables for the values in the fuzzy tensor. In this article, locally optimal patterns for that model, with high areas times squared densities,...

Introduction: Chronic increases in aldosterone (Aldo) levels (hyperaldosteronism) increases blood pressure and induces hypertension. In the cardiovascular system, Aldo stimulates reactive oxygen species (ROS) generation. ROS contribute to vascular dysfunction by increasing vascular smooth muscle contractile...

The objective of this study is to assess the relationship between alcohol taxation changes and drinking initiation among adolescents and young adults (collectively “youth”) in Thailand (a middle-income country). Using a survey panel, this study undertook an age-period-cohort analysis using four large-scale...

Background: Increased risk for cardiovascular diseases is associated with diabetes, can be partially attributed to endothelial dysfunction. However, the cumulative factors leading to endothelial dysfunction in Type 2 DM are not clear. In the current study, a novel attempt was made to understand factors...

Background: Stiffening of the aorta has been associated with microvascular structural brain damage and cognitive dysfunction in cross-sectional and longitudinal studies, probably due to the reduced wave reflection at the interface between carotid and aorta and transmission of excessive flow pulsatility...

In the literature of graph theory, networks are represented as directed graphs or undirected graphs and a mixed of both combinations. In today's era of computing, networks like brain and facebook that do not belong to any of the mentioned networks category and in fact, it belongs to the combination...

One of the key issues in the theory of concept lattices is to extract the useful rules from the decision formal context. The maximal rules implicate the others, thus people are interested in them. This paper proposes two new kinds of attribute reduction in the decision formal context based on maximal...

Genetic algorithm (GA) is a search algorithm based on the theory of Darwin. For the purpose of improving the convergent rate and maintaining the population diversity in GA, this paper presents a new genetic operator called trisecting group and directional selection mechanism (TDGA), in which the worst...

Elevation of plasma [K+] and [angiotensin II] (Ang II), two major physiological stimuli of adrenal zona glomerulosa cells, increase aldosterone production by triggering cytosolic Ca2+ signalling. Cytosolic Ca2+ signals are accompanied by mitochondrial Ca2+ elevations which further strengthen this steroidogenic...

Purpose/Background: We previously demonstrated in both longitudinal study and meta-analysis (pooled relative-risk RR, 2.45)[1,2] that all-cause and cardiovascular mortality is significantly higher in people with diabetes foot ulceration (DFU) than with those without a foot ulcer. In this prospective...

Background: Aortic dissection is a devastating condition, beginning with a tear through from intima to the medial layer, leading to splitting of aortic layers and creating the false and true lumen with a septum (or flap). Little is known about the properties of the dissection flap. Aim: To determine...

Objectives: Central pulse pressure (cPP) is responsible for vital organ hemodynamics, [1,2] and its monitoring is important for cardiovascular disease prevention. [3] Excess sodium intake and (micro)albuminuria, a manifestation of renal microvascular damage, are also known as strong predictors of cardiovascular...

Purpose: Understanding and prediction of ascending thoracic aortic aneurysms (ATAA) progression are not well established yet and aortic dissection is frequently occurring on normally sized and mildly dilated aortas. Despite known theoretical associations between pressures and blood flow patterns there...

A novel fuzzy rough granular neural network (NFRGNN) based on the multilayer perceptron using backpropagation algorithm is described for fuzzy classification of patterns. We provide a development strategy of knowledge extraction from data using fuzzy rough set theoretic techniques. Extracted knowledge...

Introduction: Unraveling aortic cellular and extracellular microstructural and mechanical mechanisms triggered to maintain homeostasis in murine aortae during maturation and aging is fundamental to better understand remodeling in human arteriopathies [1]. Methods: This study, combining ex-vivo extension-inflation...

Background & Purpose: The femoral bifurcation houses complex flow recirculation that may be impacted by downstream peripheral resistance; however, conventional ultrasound is unable to quantify multi-directional flow to study these phenomena. The purpose of this study was to examine the multi-directional...

The prevalence rates of β-thalassemia (β-thal) and Sickle Cell Disease (SCD) in Saudi Arabia are considered one of the highest compared to surrounding countries in the Middle East (0.05% and 4.50%, respectively). In this study, Secondary data analysis was obtained from the premarital screening and genetic...

Purpose/Background/Objective: Cognitive decline is highly prevalent amongst end-stage renal disease (ESRD) patients and is accelerated upon initiation of hemodialysis (HD) [1]. ESRD increases aortic stiffness and blood flow pulsatility, which may damage small vessels of target organs like the brain [2]....

This paper comprises a new iterative method for multi-person decision making based on multiplicative consistency with incomplete reciprocal preference relations (IRPRs). Additionally, multiplicative transitivity property of reciprocal preference relation (RPR) is used at the first level to estimate the...
