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.

Wrist Photoplethysmography Pulse Waves: Morphological Classes and Physiological Influences

Engineering Proceedings
Wearables such as smartwatches provide opportunity for large-scale cardiovascular health monitoring. Wearables often use photoplethysmography (PPG), an optical sensing technique, to measure the arterial pulse wave and derive insights into cardiovascular ...

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 ...

Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

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 ...

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 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 ...

Neurovascular Contacts in the Pathophysiology of Neuralgic Amyotrophy: An Observational Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuralgic amyotrophy (NA) is a prevalent, monophasic, multifocal immune‐mediated neuropathy. A distinctive characteristic of the disease is the occurrence of nerve or fascicle constrictions and torsions (NA‐associated focal nerve lesions, NAFL). The pathophysiology underlying this phenomenon remains to be fully elucidated.

Integration of Serum Neurofilament Light Chain and Cortical Dysfunction Improves Diagnostic Accuracy in ALS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether integration of serum neurofilament light chain (NfL) and cortical dysfunction improves diagnostic accuracy in amyotrophic lateral sclerosis (ALS) when applied alongside the Gold Coast criteria (GCC). Methods In this prospective study, 148 participants with suspected ALS were recruited (101 ALS and 47 with ALS ...
