Background: The objective of the study was to apply wave intensity analysis (WIA) in the pulmonary artery to characterise the magnitude, origin, type and timing of arterial waves in individuals with and without pulmonary hypertension (PH). Methods: Right heart catheterisation was performed using a pressure...

Independent learning is a condition where students have control over their own learning. This is very essential when we in the new normal era, considering that independent learning affects the success of learning activities. This study investigated students’ learning independence and then presents the...

PDAC is inherently lethal, which can be mostly explained by late detection and low sensitivity of visual inspection during contrast-enhanced CT. Minor changes in the textures, isoattenuation lesions, and large inter-observers’ variability still remain obstacles to consistent detection. AI-based methods...

Introduction: Aortic stiffness predicts cardiovascular mortality but is limited as a risk marker because it is dependent on blood pressure (BP). A potential solution is provided from the ratio of aortic-to-brachial artery stiffness (ab-ratio), which is purported to be a BP-independent risk marker among...

Background: Accuracy of brachial cuff blood pressure (BP) may be influenced by individual variability in central-to-peripheral systolic BP (SBP)-amplification, but this has never been determined. We aimed to achieve this by characterising SBP-amplification phenotypes and examining associations with cuff...

Introduction: Hypertension is associated with stiffening of blood vessels, reduced arterial lumen and reduced cerebral blood flow; however, it is not known how lower cerebral blood flow relates to arterial structure or impacts on wave dynamics. We hypothesise increased backward wave energy and faster...

Background: Mean arterial pressure (MAP) and diastolic blood pressure (DBP) are thought to consistently decline approximately 1–3 mmHg from the aorta to peripheral large arteries, thus providing a small pressure gradient to aid blood flow. The magnitude of this gradient is important for correct waveform...

Objective: Reservoir-excess pressure measured using tonometry methods predicts cardiovascular events, but the operator-dependency of tonometry is an impediment to widespread use. A cuff-based blood pressure device has been developed to derive reservoir-excess pressure from measured brachial pressure...

Purpose/ background/ objectives: People with or at risk of Type II diabetes (T2DM) are at increased risk of vascular disease and arterial stiffness (AS). We hypothesized that spironolactone and dietary nitrate (beetroot juice) separately and together would reduce AS, measured as cardiac-ankle vascular...

Symmetry classification of two-body central potentials in a two-particle Schrödinger equation in terms of contact transformations of the equation has been investigated. Explicit calculation has shown that they are of the same four different classes as for the point transformations. Thus in this problem...

A brief review is presented of the two recent perturbation algorithms. Their common idea lies in a not quite usual treatment of linear Schrödinger equations via nonlinear mathematical means. The first approach (let us call it a quasi-exact perturbation theory, QEPT) tries to get the very zero-order approximants...
