Hydrogen Sulfide (H2S) and the Cardiovascular System
Hydrogen sulfide (H2S) has relatively recently been added to a list of endogenously produced gaseous signalling molecules. Our understanding of the science of H2S has advanced rapidly in recent years as exemplified by the fact that, within a mere 10 years, a range of H2S releasing drugs have …

Corticosteroid hormone action in the cardiovascular system
The cardiovascular system (CVS) has emerged as an important target of corticosteroid hormones. Mineralocorticoid receptor antagonists provide cardiovascular protection and are now routinely used in disorders such as primary hyperaldosteronism, resistant hypertension and congestive heart failure …

Multi-Scale Fluid Flow Analysis of the Cardiovascular System
<p>The hypoplastic left heart syndrome (HLHS) is one of the rarest congenital heart diseases affecting infants. Out of 150 babies born, one baby suffers from congenital heart disease. Furthermore, nine percent out of those suffering from congenital heart disease specifically suffer from hypoplastic …

Monitoring and control of the cardiovascular system during indoor exercise
… and economic concern worldwide. Modern treadmill systems can provide effective, safe and practical indoor exercise for the consumption of extra energy. However, an uncontrolled treadmill can cause excessive exertion on the cardiovascular system. To avoid excessive cardiovascular stress, an …

Roles of Class II Histone Deacetylases in the Cardiovascular System
Histone acetylation/deacetylation, which is orchestrated by two opposing families of enzymes, histone acetyltransferases (HATs) and histone deacetylases (HDACs), represents one of the fundamental mechanisms to control gene transcription. Class II histone deacetylases regulate developmental and …

Effects of nutrition and ultrasound imaging on the cardiovascular system
… diagnostic situations ranging from pregnancy to cardiovascular disease and cancer. Ultrasound imaging can be performed with concomitant intravenous administration of microbubble contrast agents to improve image clarity. While useful for imaging of the cardiovascular system, concerns have been …

A forward model-based analysis of cardiovascular system identification methods
Cardiovascular system identification is a potentially powerful approach for intelligent patient monitoring of cardiovascular function. Rather than merely recording hemodynamic signals, the signals are mathematically analyzed so as to provide a dynamical characterization of the physiologic …

Alterations in cardiovascular regulation and function assessed using cardiovascular system identification
Thesis (S.B. and M.Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2000.

Potential influence of serum uric acid concentration on regulation of the human cardiovascular system
… serum uric acid concentrations and increased cardiovascular risk. However, it is unclear if uric acid is an independent causal risk factor, serves a protective role due to its antioxidant properties, or simply acts as a passive marker of risk through association with other factors. The …

Direct Effect of Glucocorticoids on the Developing Cardiovascular System: Studies in the Chicken Embryo
… may have a detrimental effect on the fetal cardiovascular system. The chicken embryo model was used to establish a clinically relevant glucocorticoid treatment at two thirds of development, without compounding influence of maternal or placental physiology, such that the direct effect of …

A numerical model of the cardiovascular system for clinical assessment of the hemodynamic state
Thesis (Ph. D.)--Massachusetts Institute of Technology, Whitaker College of Health Sciences and Technology, 1996.

The effects of early life nutrient restriction on the cardiovascular system of the adult sheep
… life is linked with a higher incidence of cardiovascular disease in adulthood. The physiological processes involved are not yet clear. The aim of this thesis was to investigate how aspects of the cardiovascular system in the adult sheep are affected by early life periods of undernutrition, …

Some Physiological Effects of the Bed Bath on the Cardiovascular System of Acute Myocardial Infarction Patients
… what physiological effects will occur in the cardiovascular system of patients with acute myocardial infarction?</p> <p>The theoretical framework for this study consisted of the following: recommendations for giving bed baths to patients with myocardial infarction; trends towards aggressive …

Time-frequency investigation of heart rate variability and cardiovascular system modeling of normal and chronic obstructive pulmonary disease (COPD) subjects
… in the heart rate variability field and the cardiovascular regulation system in normal and Chronic Obstructive Pulmonary Disease (COPD) subjects. It explores the correlations between heart rate variability and cardiovascular regulation, which interact through complex multiple feedback and …

Exploring the therapeutic potential of the apelin receptor signalling axis, and angiotensin-converting enzyme 2 (ACE2) as the SARS-CoV-2 viral entry receptor, in the cardiovascular system
… cardiac inotropy and vasodilatation in the cardiovascular system. The apelin receptor provides a tractable therapeutic target for multiple cardiovascular diseases, such as pulmonary arterial hypertension, heart failure, and bleeding disorders, where the receptor also mediates antithrombotic …

The impact of thyroid dysfunction on cardiovascular risk
… and hyperthyroidism) have major impacts on the cardiovascular system. Whilst the short term effects of thyroid dysfunction on the cardiovascular system are clinically obvious and well studied, the long term effects and particularly the size of its effects on the cardiovascular system remain …
