Regulation of Heart Beats by the Autonomous Nervous System in Health and Disease: Point-Process-Theory based Models and Simulation [V-I] [PDF]

open access: yesarXiv, 2019
We have advanced a point-process based framework for the regulation of heart beats by the autonomous nervous system and analyzed the model with and without feedback. The model without feedback was found amenable to several analytical results that help develop an intuition about the way the heart interacts with the nervous system.

Oxidative Stress in the Brain Causes Hypertension via Sympathoexcitation

open access: yesFrontiers in Physiology, 2012
Activation of the sympathetic nervous system has an important role in the pathogenesis of hypertension, and is determined by the brain. Previous many studies have demonstrated that oxidative stress, mainly produced by angiotensin II type 1 (AT1) receptor

Mathematical models of cardiovascular control by the autonomic nervous system [PDF]

open access: yesarXiv, 2018
This PhD thesis develops an integrated mathematical model for autonomic nervous system control on cardiovascular activity. The model extensively covers cardiovascular neural pathways including a wide range of afferent sensory neurons, central processing by autonomic premotor neurons, efferent outputs via preganglionic and postganglionic autonomic ...

Heart rate variability in marketing research: A systematic review and methodological perspectives

open access: yesPsychology &Marketing, Volume 40, Issue 1, Page 190-208, January 2023., 2023
Abstract Heart rate variability is a promising physiological measurement that accesses psychophysiological variations in response to a marketing stimulus. While its application spans diverse fields, there is a limited understanding of the usability and interpretation of heart rate variability in marketing research.

THE PARTICIPATION OF CATECHOLAMINES IN THE PATHOGENESIS OF DIABETIC CARDIOMYOPATHY

open access: yesMedicina v Kuzbasse, 2020
Under normal conditions, the sympathetic nervous system, through its main mediators (catecholamines) plays an important role in the functioning of the cardiovascular system.

Tumor-induced neoneurogenesis and perineural tumor growth: a mathematical approach [PDF]

open access: yesarXiv, 2015
Primary tumors infrequently lead to demise of cancer patients; instead, mortality and a significant degree of morbidity result from the growth of secondary tumors in distant organs (metastasis). It is well-known that malignant tumors induce the formation of a lymphatic and a blood vascular network around themselves.

QTc Interval Changes in Preeclampsia vs. Normal Pregnancy: A Systematic Review and Meta‐Analysis

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Pregnancy induces significant adaptations in the cardio‐autonomic nervous system, with additional cardiac stress in preeclampsia potentially impacting ventricular repolarization. Despite the widespread use of QT‐prolonging drugs during pregnancy, the extent of heart rate (HR)‐corrected QT (QTc) interval changes during normal pregnancy and preeclampsia ...

Assessing the Level of Autonomic Nervous Activity for Effective Biofeedback Training [PDF]

open access: yesarXiv, 2019
This paper proposes a prototype of a new biofeedback training based on mathematical models of cardiovascular control. For this purpose we develop a low-cost device that is able to record and process arterial pulse wave via photoplethysmograph and skin temperature on the peripheral part of the arm. A benchmark analysis of our device against a registered
