Frontiers in Pharmacology, 2020 BackgroundThe importance of dietary potassium in health and disease has been underestimated compared with that placed on dietary sodium. Larger effort has been made on reduction of sodium intake and less on the adequate dietary potassium intake, although

Compact integral manifolds of differential systems [PDF]
arXiv, 2010 The boundedness tests for the number of compact integral manifolds of autonomous ordinary differential systems, of autonomous total differential systems, of linear systems of partial differential equations, of Pfaff systems of equations, and of systems of exterior differential equations are proved.

Using Structure-Behavior Coalescence Method for Systems Definition 2.0 [PDF]
arXiv, 2021 Systems definition is an artifact created by humans to describe what a system is. A system has been defined, by systems definition 1.0, hopefully to be an integrated whole, embodied in its components, their interrelationships with each other and the environment, and the principles and guidelines governing its design and evolution.

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Coronary slow flow and no reflow significantly predict poor prognosis in acute myocardial infarction (AMI) patients, especially those with chronic kidney disease (CKD). Early identification of factors contributing to these conditions can mitigate ischemic events and improve outcomes.

Aliskiren: An orally active renin inhibitor
Journal of Pharmacy and Bioallied Sciences, 2011 Renin inhibitors are antihypertensive drugs that block the first step in the renin-angiotensin system. Their mechanism of action differs from that of the angiotensin-converting enzyme inhibitors and angiotensin-receptor antagonists, but like these drugs,

High salt intake damages the heart through activation of cardiac (pro) renin receptors even at an early stage of hypertension. [PDF]
PLoS ONE, 2015 It has not yet been fully elucidated whether cardiac tissue levels of prorenin, renin and (P)RR are activated in hypertension with a high salt intake.

Morphisms of Networks of Hybrid Open Systems [PDF]
arXiv, 2019 This thesis (defended 10/07/2019) develops a theory of networks of hybrid open systems and morphisms. It builds upon a framework of networks of continuous-time open systems as product and interconnection. We work out categorical notions for hybrid systems, deterministic hybrid systems, hybrid open systems, networks of hybrid open systems, and morphisms

Contraction analysis of time-varying DAE systems via auxiliary ODE systems [PDF]
arXiv, 2023 This paper studies the contraction property of time-varying differential-algebraic equation (DAE) systems by embedding them to higher-dimension ordinary differential equation (ODE) systems. The first result pertains to the equivalence of the contraction of a DAE system and the uniform global exponential stability (UGES) of its variational DAE system ...

Epigenetic Changes Related to Hypertension in Asian Adults: A Systematic Review
Chronic Diseases and Translational Medicine, EarlyView.PRISMA study flow diagram. ABSTRACT Background Elevated high blood pressure is controlled by complicated, little‐understood genetic and epigenetic pathways that are influenced by both heritable and environmental variables. Many adult systolic and diastolic blood pressure‐related genomic loci have been identified through previous genome‐wide association

Brazilian Journal of Medical and Biological Research, 2001 In the present study, we investigated the involvement of the brain renin-angiotensin system in the effects of central cholinergic stimulation on blood pressure in conscious, freely moving normotensive rats. In the first step, we determined the effects of
