Heart rate variability has been largely used for the assessment of cardiac autonomic activity,
due to the direct relationship between cardiac rhythm and the activity of the sympathetic and …

Photoplethysmography is a key sensing technology which is used in wearable devices such
as smartwatches and fitness trackers. Currently, photoplethysmography sensors are used to …

Introduction: Heart Rate Variability (HRV) and Pulse Rate Variability (PRV), are non-invasive
techniques for monitoring changes in the cardiac cycle. Both techniques have been used for …

Abstract Objective Pulse Rate Variability (PRV) has been widely used as a surrogate of
Heart Rate Variability (HRV). However, there are several technical aspects that may affect …

Estrogen deficiency after menopause is associated with autonomic nervous changes,
leading to memory impairment and increased susceptibility to Alzheimer's disease (AD) …

The clinical use of doxorubicin, an effective chemotherapeutic is hampered by the
development of irreversible cardiotoxicity. Here we test time-frequency analysis of heart rate …

Experimentally induced oscillatory shear stress (OSS) and hypoxia reduce endothelial
function in humans. Acute and sustained hypoxia may cause increases in resting OSS; …

We investigated the mechanism by which ACE2 (angiotensin-converting enzyme 2)
overexpression alters neurohumoral outflow and central oxidative stress. Nrf2 (nuclear factor …

Diabetic nephropathy (DN) is a leading cause of end-stage renal disease in developed
countries where type 2 diabetes mellitus has reached epidemic proportions. Although the …

Elevated sympathetic tone and activation of the renin–angiotensin system are
pathophysiologic hallmarks of hypertension, and the interactions between these systems are …
