Abstract:

Hemodynamic effects of insulin resistance (IR) are thought to be largely dependent on its relationship with body mass index (BMI) and blood pressure (BP) levels. The first part of the present thesis was aimed at exploring whether IR is associated with hemodynamic indices of cardiovascular function in a large sample of non-diabetic individuals from the general population (n=731) and if so, to explore if such relationship is continuous across different categories of BMI (lean, overweight and obese), and BP (normal BP, high-normal BP and hypertension). IR was assessed with the homeostasis model a

Abstract:

Central aortic systolic blood pressure (cSBP) differs from peripheral systolic blood pressure (pSBP) measured in the arm. cSBP may be estimated non-invasively by application of a generalised transfer function (GIF) to a high fidelity peripheral arterial waveform or from the late systolic shoulder (SBP2) of such a waveform. The relative accuracy of these estimates and the degree to which they depend on the accuracy of peripheral blood pressure is unknown. The interest in estimates of central blood pressure is driven in large part by the fact that aortic pulse pressure (cPP) is thought to be a b

Abstract:

Background High blood pressure is associated with an increased risk of cardiovascular disease and premature death. The shape of association between blood pressure and the risk of cardiovascular events is debated. Some researchers suggest that the association is linear or log-linear, whereas others suggest it is J-shaped. Randomized controlled trials of antihypertensive treatment have been successful in hypertension, but ambiguous in the high normal blood pressure range. Previous systematic reviews have not found any interaction between baseline systolic blood pressure and treatment effect, wit

Abstract:

African Americans disproportionately develop cardiovascular disease risk factors including high blood pressure and high cholesterol levels in comparison to European Americans. The purpose of this study was to examine the associations of diet quality and physical activity with blood pressure levels and cholesterol levels among African Americans. The social ecological model was the theoretical foundation for the study. Research questions were designed to examine the extent to which diet quality and physical activity predict blood pressure levels and cholesterol levels. The research design was qu

Abstract:

With the rise in prevalence of cardiovascular (CV) disease, risk stratification is becoming increasingly important. Accurate characterization of the CV system is required, for which central aortic blood pressure (BP) parameters form an integral part. However, invasive measurement of central aortic BP parameters (aP) is difficult. Therefore, non-invasive methods to estimate aP from the radial pressure pulse (rPulse) have been proposed. To analyze accuracy of estimated aP (aPhat) and applicability in risk stratification and diagnosis, this study presents: (1) a novel representation of the rPuls

Background Central arterial hemodynamics, arterial stiffness and arterial structure are predictive of cardiovascular events and outcomes in adulthood. The tools to measure these parameters have largely been developed and validated in adults, but poorly investigated in children. With increasing interest in cardiovascular risk assessments earlier in life, it is imperative to critically appraise the techniques to measure these parameters in childhood to ensure validity of measurement, and to understand what these parameters mean with regards to association with future cardiovascular disease outco

Abstract:

A large body of research suggests self-perception of stressful experiences is not always a good predictor of stress biomarkers. On this front, anthropologists have an opportunity to disentangle the interactions between individual perceptions of stress and the stress response. To better understand these interactions we chose a sampling frame that allows individual participants to self-identify as high, medium, and low stress responders. We chose to conduct this research in an undergraduate student community for two reasons: 1) final exams serve as a similarly timed stressor, 2) given the percei

Hypertension is the chronic elevation in blood pressure that is regulated in part through the retention and regulation of sodium retention and excretion in the kidneys. Hence the kidney has been considered the organ that regulates blood pressure.

Arterial stiffness is one of the earliest detectable manifestations of adverse structural and functional changes within the vessel wall. It is well known that increased large artery stiffness independently predicts the cardiovascular risk in a variety of populations. The identification of populations at higher risk of increased arterial stiffness and the knowledge of the mechanisms involved in arterial stiffening may help to identificate pharmacological and other treatments to reduce the arterial stiffness and improve the outcome of the patients.

Abstract:

Metabolic syndrome is associated with pathologies that include type 2 diabetes, hypertension, and dyslipidemia, all of which increase the risks of heart disease. Glucagon-like peptide (GLP-1) is a hormone produced by intestinal enteroendocrine L‑cells. GLP-1 increases insulin sensitivity, augments glucose-dependent insulin secretion, and suppresses glucagon release. GLP-1 also works centrally to decrease appetite and increase metabolism. Evidence suggests that the beneficial effect is mediated by metabolically related sympathetic neurons within the hypothalamus. Although the hypothalamus conta

O objetivo deste trabalho foi avaliar o efeito da microinjeção de GLU, GABA, OT, SST e Ang II microinjetados diretamente no AMePD de ratos não anestesiados s

Abstract:

Background: Seasonal fluctuations in outdoor temperature have been shown to affect blood pressure in adults. We have asked whether or not there is either a seasonal variation or an influence of outdoor temperature on blood pressure measurements in children and adolescents in middle Europe. Methods: Blood pressure was routinely measured in healthy and sick children and adolescents in outpatient clinics and during hospitalisation in a total of 6714 subjects (3,497 boys/3,237 girls), age 3 to 21 years, with a median of 10.6 years. Results: Cross-sectional analysis showed a significant seasonal va

Abstract:

Cardiovascular disease varies by ethnicity in the UK. South Asians (SA) have higher coronary heart disease (CHD) and diabetes prevalence, while African-Caribbeans (AfC) have greater stroke, but intriguingly lower CHD rates despite higher blood pressures and diabetes risk than Europeans. Conventional risk factors do not fully explain such differences. This cross-sectional study tested the hypothesis that the hormones, vitamin D measured as 25(OH)D and aldosterone, would be independently associated with intermediate cardiovascular outcome markers in these ethnic groups.

Abstract:

This thesis explores the various meanings and implications of transparency in architecture and in learning environments in particular. Architectural transparency, achieved through choice of materials and principles of formal composition, creates a diversity of relationships and can facilitate visual, conceptual, and functional clarity as well as offering simultaneous perception of different spaces. It offers a range of phenomenological qualities and so provides an opportunity to explore and complicate such dichotomies as translucency and opacity, openness and closure, and public space and pr

Abstract:

The central aortic blood pressure signal is an important source of information that contains cues about the cardiovascular system condition. Measuring this pulse wave clinically is burdensome as it can be only measured invasively with a catheter. As a result, many mathematical tools have been proposed in the past few decades to reconstruct the aortic pressure signal from the peripheral pressure signals that are usually easier to obtain noninvasively. At the distal level, the blood pressure signal is not directly useful since factors, such as length and stiffness of the arteries, play roles in

Abstract:

High blood pressure (BP) is the leading modifiable risk factor for cardiovascular disease (CVD) and death. However, conventional brachial systolic and diastolic BP provide limited information on the underlying BP waveform and do not encompass all the cardiovascular risk associated with BP. Moreover, evidence suggests central (aortic) BP may be more clinically useful than conventional brachial BP, highlighting the importance of differences in central-to-peripheral vascular properties and arterial hemodynamics in the assessment of BP related risk. Recently, the reservoir-excess pressure model ha
