[Oscillations in the cardiovascular system--physical models for the interpretation of physiological phenomena].

Kardiologia polska, 2012
We discuss the foundations of the theory of homeostasis within the framework of modern physics. We analyse the paradigm of homeostasis, which is based on the physical assumption that the internal environment undergoes random fluctuations around a steady state equilibrium. We show how the notion of homeodynamics extends the concept of homeostasis.

Heart Rate Variability in Young Adults with Bronchial Asthma with and without Previous COVID-19 Infection: A Cross-sectional Study

Journal of Clinical and Diagnostic Research
Introduction: Heart Rate Variability (HRV) is a validated, non invasive measure of Autonomic Nervous System (ANS) function. Both bronchial asthma and post Coronavirus Disease-2019 (COVID-19) syndrome are independently associated with autonomic ...

Hypoxia Tolerance in Teleosts: Implications of Cardiac Nitrosative Signals

Frontiers in Physiology, 2018
Changes in environmental oxygen (O2) are naturally occurring phenomena which ectotherms have to face on. Many species exhibit a striking capacity to survive and remain active for long periods under hypoxia, even tolerating anoxia.

β-Hydroxybutyrate as an epigenetic modifier: Underlying mechanisms and implications

Heliyon, 2023
Previous studies have found that β-Hydroxybutyrate (BHB), the main component of ketone bodies, is of physiological importance as a backup energy source during starvation or induces diabetic ketoacidosis when insulin deficiency occurs. Ketogenic diets (KD)

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

Arthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

The Lupus Damage Index Revision Program: Results From the Item Generation and Reduction Phases

Arthritis Care &Research, EarlyView.
Objective A data‐driven and expert/patient consensus‐based project to develop a revised Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology (ACR) Damage Index (SDI) is under way supported by SLICC, ACR, and the Lupus Foundation of America. Our objective is to report the item generation and reduction phase results

Creatine monohydrate increases skeletal muscle microvascular blood flow and promotes lipid mobilization in postmenopausal women

Journal of the International Society of Sports Nutrition
Background Postmenopausal females have an elevated cardiovascular disease (CVD) risk, induced partly by reduced skeletal muscle microvascular blood flow (SMBF), elevated reactive oxygen (ROS), and impaired meal metabolism (glycerol, glucose, lactate ...

Anorectal Dysfunction in Systemic Sclerosis: Clinical Phenotypes and Functional Patterns

Arthritis Care &Research, EarlyView.
Objective The aim of this study was to characterize specific physiologic defects in anorectal dysfunction in systemic sclerosis (SSc) using anorectal manometry (ARM), evaluate associations with gastrointestinal (GI) and extraintestinal clinical phenotypes, and explore potential serologic markers for risk stratification.

Individuals With Multijoint Osteoarthritis Demonstrate Larger Longitudinal Declines in Frailty: Data From the Canadian Longitudinal Study on Aging

Arthritis Care &Research, EarlyView.
Objective The aim of this study was to test the hypothesis that multijoint osteoarthritis would modify the relation between time and frailty progression, in which more affected joints would lead to larger declines over six years compared to those without osteoarthritis using data from the Canadian Longitudinal Study on Aging.
