Pulse wave analysis and pulse wave velocity techniques: are they ready for the clinic? [PDF]

Hypertension Research, 2010
interestingly describe animportant factor when arterial stiffness is clini-cally assessed: subject’s body position. Althoughthis is an important question, especially ifwe want to bring this research tool to the clinicin a regular basis, there are several other factorsthat should be considered.

Aortic pulse wave velocity and augmentation index@75 measured by oscillometric pulse wave analysis in Gujarati nonhypertensives

Vascular Investigation and Therapy, 2018
BACKGROUND: Augmentation indexes (AIxs) and pulse wave velocity (PWV) are arterial stiffness parameters. They can be studied by pulse wave analysis (PWA) noninvasively.

Reproducibility of pulse-wave analysis and pulse-wave velocity determination in chronic kidney disease [PDF]

Nephrology Dialysis Transplantation, 2007
Indices of central arterial stiffness, derived by use of applanation tonometry, have shown to be strong independent predictors of cardiovascular morbidity and mortality in patients with chronic kidney disease (CKD). The objective of this study was to evaluate the intra- and inter-observer and day-to-day reproducibility of pulse-wave analysis (PWA) and ...

Development of pressure-pulse-sensor using a gyro sensor for postprandial blood glucose level estimation

Nihon Kikai Gakkai ronbunshu, 2021
Self-measurement of blood glucose is usually done using a drop of blood from the fingertip. Non-invasive methods have been studied vigorously, but have not been put into practical use because of difficulties resolving problems of portability, accuracy ...

A non-invasive blood viscosity detecting method based on pulse wave [PDF]

MATEC Web of Conferences, 2020
A non-invasive blood viscosity detection method based on pulse wave is proposed. The method establishes a relationship equation between blood viscosity and peripheral resistance, arterial compliance, and pulse wave waveform characteristics by extracting ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Epilepsy‐Associated Variants of a Single SCN1A Codon Exhibit Divergent Functional Properties

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Pathogenic variants in SCN1A, which encodes the voltage‐gated sodium channel NaV1.1, are associated with multiple epilepsy syndromes exhibiting a range of clinical severity. SCN1A variants are reported in different syndromes, including Dravet syndrome, which is associated with loss‐of‐function, whereas neonatal/infantile‐onset ...

A unified mechanism for the water hammer pulse and pulsus bisferiens in severe aortic regurgitation: Insights from wave intensity analysis

Artery Research, 2017
The carotid bisferiens pulse and the radial water hammer pulse are typical of severe chronic aortic regurgitation. Little is known about the mechanism of these classic cardiovascular signs identified on physical examination.

Research on Electromagnetic Susceptibility of Electronic Modules in Component-Level HEMP PCI Test

Energies, 2022
The study of electromagnetic sensitivity of electronic modules is crucial for the selection of a component-level pulse current injection (PCI) waveform, which will determine whether a component-level PCI test is equivalent to a system-level pulse ...

Aquaporin‐4 in Narcolepsy Type 1: Investigation of Perivascular Fluid Movement in Sleep Disorders

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Narcolepsy type 1 (NT1) is caused by the loss of hypocretin‐1 leading to excessive daytime sleepiness and cataplexy. Additionally, disrupted nighttime sleep has become an increasingly recognized feature of NT1. As the glymphatic fluid movement has been linked to sleep architecture, we investigated cerebrospinal fluid (CSF) Aquaporin‐4 (AQP4 ...
