CHSS 2019 Abstracts: Pulsatile Perfusion Of Cardiovascular Progenitor Cells Drives Vascular Smooth Muscle Differentiation And A Contractile Phenotype

Consumption of carbohydrates has been demonstrated to alter resting cardiovascular function and cardiovascular reactions to mental stress (known as cardiovascular reactivity). Previous investigations of the effects of acute carbohydrate administration on cardiovascular reactivity suggest that ingestion of glucose followed by mental stress alters hemodynamic responses by attenuating elevations in cardiac output and increasing total peripheral resistance. However, these prior investigations have utilized tasks which have limited generalizability to real-life stressors and were conducted with participants in a recumbent position. The present study investigated the effects of oral glucose administration on resting cardiovascular parameters and cardiovascular reactivity in twenty four seated healthy male college students. Interpersonal speech and anger recall tasks were utilized to elicit a greater emotional response than those used in previous studies and to more closely mirror stressors encountered ...

Cardiovascular System - Cardiovascular System Diagram - Cardiovascular System Chart - Cardiovascular Diagram - Cardiovascular system is a visual representation of the human organs carrying blood through the body including human heart, veins, arteries and aorta.

There are several possible explanations for the dominant effect of age on the likelihood for occurrence of these cardiovascular diseases. One is that aging is synonymous with disease; however, many people achieve old age without evidence of these diseases. Another explanation for the epidemic of cardiovascular disease in older persons is that other defined risk factors co-vary in number or severity with increasing age. A related, but distinct, idea is that increasing age contributes to an increased exposure time to these other age-dependent risk factors. According to this view, time indirectly confers an increased risk for the occurrence and increased severity and extent of pathophysiological manifestations of these diseases in older persons. A somewhat different view is that cardiovascular structure and function change with time because an aging process, and that, over time, this process alters the substrate on which specific pathophysiological disease mechanisms, such as those that have ...

VÁLYI Péter. [The world population in both industrialized and developing countries is aging. The clinical and economic implications of this demographic shift are staggering because age is the most powerful risk factor for cardiovascular diseases. The incidence and prevalence of hypertension, coronary artery disease, congestive heart failure, and stroke increase steeply with advancing age. Although epidemiologic studies have discovered that some aspects of lifestyle and genetics are risk factors for these diseases, age, per se, confers the major risk. There is a continuum of age-related alterations of cardiovascular structure and function in healthy humans, however these alterations are not synonymous with diseases processes. Old age is not a disease. Although cardiovascular aging changes are considered normative, they lower the threshold for development of cardiovascular disease, and appear to influence the steep increases in hypertension, atherosclerosis, stroke, left ventricular ...

Cardiologists and oncologists must work together in an attempt to avoid or prevent adverse cardiovascular effects in patients from certain chemotherapies, especially for those who may be at a higher risk for such effects, according to a new review published online December 10 in the Journal of the National Cancer Institute.. With an aging population, it is highly probable that an increasing number of people may have both cancer and cardiovascular disease. Many chemotherapeutic and chemoprevention drugs affect the cardiovascular system, making cardiovascular side effects a new challenge in cancer therapy.. In a review of the literature, Adriana Albini, Ph.D., Chief of Oncology Research of the Clinical and Research Institute MultiMedica, Milan, Italy, Francesco Donatelli, Chief of MultiMedica Cardiovascular Department, and others from the Universities of Milan, Genova and Varese, summarize the potential cardiovascular toxicities for a range of cancer chemotherapeutic and chemopreventive agents and ...

The circulatory system is a closed system in which the heart consists of two pumps in series. During pulmonary circulation, blood rich in oxygen is pumped into the left atrium of the heart from the lungs, whereas blood low in oxygen exits the heart through the right ventricle to the lung. The main function of the circulatory (or cardiovascular) system is to deliver oxygen to the body tissues, whilst simultaneously removing carbon dioxide produced by metabolism. The blood carries oxygen and nutrients to every cell of the body. The cardiovascular system helps regulate the temperature with the following: Balancing the fluids in the body means that every cell gets the proper amount of electrolytes, nutrients and gases. These are the main roles of the circulatory system. 5. The circulatory system carries oxygen, nutrients, and . It transports oxygen and other essential substances throughout the body, fights sickness, and performs other vital functions. Blood is propelled by the heart, with arteries, ...

Challenge and threat reflect two distinct psychophysiological approaches to motivated performance situations. Challenge is related to superior performance in a range of tasks compared to threat, thus methods to promote challenge are valuable. In this paper we manipulate challenge and threat cardiovascular reactivity using only resource appraisals, without altering perceived task demands between challenge and threat conditions. Study 1 used a competitive throwing task and Study 2 used a physically demanding climbing task. In both studies challenge task instructions led to challenge cardiovascular reactivity and threat task instructions led to threat cardiovascular reactivity. In Study 1, participants who received challenge instructions performed better than participants who received threat instructions. In Study 2, attendance at the climbing task did not differ across groups. The findings have implications for stress management in terms of focusing on manipulating appraisals of upcoming tasks by ...

Moving blood throughout the body, the circulatory system, also called the cardiovascular system, comprises 4 parts, the heart, arteries, blood, capillaries, and veins. This system stabilizes body temperature and pH, maintains homeostasis, moves nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells into and out of the cells nourishing and fighting disease, while simultaneously keeping us alive [1-2].. This transport of oxygenated blood from the lungs and heart throughout the body occurs through the arteries. As heart disease remains the number one cause of death, coronary artery disease, heart failure, heart attack, arrhythmia, and other cardiovascular conditions such as hypertension and high blood cholesterol levels can damage the cardiovascular system [3-4].. We often overlook the importance of sufficiently effective blood flow to the brain, when considering the mood and cognitive disorders. In studies, we find an improvement in mood and cognition, ...

Research summary:. Lipid mediators as prostanoids and cholesterol derivatives play an essential role in inflammatory processes associated to the onset and development of a number of pathologies as cardiovascular diseases. Prostanoids participate in the inflammatory response and exert important actions in the cardiovascular system, modulating vascular homeostasis and participating in the pathogenesis of vascular diseases. Their importance in inflammation and in maintaining cardiovascular homeostasis is highlighted by clinical experience with drugs inhibiting their production as NSAIDs. In spite of their well-known properties as anti-inflammatory drugs, recent studies have shown that cyclooxygenase-2 selective NSAIDs inhibitors increase the risk of adverse cardiovascular side effects. On the other hand, oxysterols and drugs acting as LXR ligands play a central regulatory role in lipid uptake, metabolism and efflux through their properties as transcriptional regulators of gene expression. In ...

Human cardiovascular system - Human cardiovascular system - Electrocardiogram: The electrical impulse that is generated by each depolarization of the heart can be characterized and examined with the use of an electrocardiogram. From a clinical standpoint, the electrocardiogram has become useful as a mechanism of diagnosing cardiac disease. The circuitry of the electrocardiogram allows the detection of small changes in voltage that occur rhythmically with cardiac excitation. It was discovered in the early 20th century that these changes could be evaluated by leads (wires) that were placed on the chest, arms, and legs. Potential differences between different sets of leads are examined throughout the cardiac cycle. Ultimately, the readout

Two programs were used to demonstrate the effects of drugs on cardiovascular function. The Virtual Cat and RatCVS software programs developed by the University of Strathclyde, Glasgow, UK offer different platforms for CVS experimentation in whole animal models. The virtual cat can be used to demonstrate the effects of 15 standard drugs and 17 unknown drugs on blood pressure and heart rate, skeletal muscle contractions, and nictitating membrane twitches. Students used this program to investigate the effects of agonists, antagonists, and vasodilators on cardiovascular function. RatCVS simulates pithed and normal rat preparations, which are suitable for demonstrating the effects of drugs on the cardiovascular system without the superimposing effects of central baroreceptor reflexes. Pithing refers to the destruction of the spinal cord and the severance of central innervation to the cardiovascular system. The software gave options of using pithed or normal rat and provided the option of using 22 ...

In the 50s, the development of medical technology has made it possible to conduct laboratory tests to identify certain factors of the human blood. These very tests indicated an increase in cholesterol and triglycerides in the blood of people suffering from cardiovascular pathologies. As required at the time, with primitive thinking, the scientists have hastily deduced a conclusion about the role of identified substances in the occurrence of human cardiovascular pathologies as well as in the resulting heart attacks and strokes. The given theory emerged about 50 years ago, while the drugs against cholesterol and triglycerides - about 30 years ago. According to the rules of logic and science, having eliminated the source of the disease, the disease itself should disappear forever. Nevertheless, nowhere in the world can anyone show a single cardiovascular patient who had recovered from this disease by taking drugs against cholesterol and triglycerides. Whereas based on the proposed theory, we had to ...

Questa meta analisi riguarda gli effetti dellesercizio aerobico sulla pressione arteriosa e si basa su ricerche cliniche randomizzate e controllate: abbiamo incluso 54 lavori su 2419 soggetti di un ampio spettro di regioni geografiche e di etnie. Lo studio ha dimostrato che lesercizio fisico ha un impressionante effetto sullabbassamento della pressione arteriosa: mmHg per la sistolica e mmHg per la diastolica. Bisogna distinguere limportanza di questi risultati per i singoli soggetti da quelli sulla salute della popolazione. La riduzione di pressione che abbiamo documentato può essere di scarsa importanza per i medici di singoli pazienti; daltra parte, una piccola riduzione della pressione media in una popolazione può ridurre in maniera eccezionale lincidenza delle malattie cardiovascolari e dei conseguenti decessi in una comunità. Tutti i tipi di esercizio sono efficaci per la riduzione della pressione. Lesercizio aerobico riduce la resistenza allinsulina e i livelli di insulina negli ipertesi.

Background: A tumor cell subset known as stem like cells (SLC) defy conventional therapies, requiring identification of SLC-specific therapeutic targets. We established that elevated COX-2 expression by breast cancer cells promotes tumor progression via inactivation of host immune cells, enhancement of cancer cell migration and invasiveness, and promotion of tumor-associated angiogenesis and lymphangiogenesis primarily by activation of the PGE-2 receptor EP4 on tumor and host cells. Cardiovascular side effects of long term use of COX-2 inhibitors argued for an alternative target, potentially EP4. Objectives/approaches: We asked whether COX-2 or EP4 additionally stimulates SLC in breast cancer. COX-2 and HER-2, often co-expressed in human breast cancer, are both major determinants of cancer progression. To define the roles of COX-2 in HER2 +ve and -ve cells, COX-2 cDNA was stably transfected into COX-2-low, HER-2-ve, ER+ve, non-metastatic MCF-7 and COX-2-ve, ER-ve, HER-2-high SKBR-3 human breast ...

What is the role of the cardiovascular system?. The cardiovascular system consists of the heart, blood, and blood vessels (veins, arteries, arterioles and capillaries). The cardiovascular system is responsible for circulating blood throughout the body providing oxygenation, homeostasis, regulation, protection and waste removal. Pulmonary circulation carries blood between the heart and lungs while systemic circulation delivers oxygenated blood to the entire body.. How does the cardiovascular system work?. The heart acts as a pumping system that forces blood into the lungs (pulmonary system) and the body (systemic system) so that oxygen, waste removal and regulation all occur. The pump forces blood into the lungs and out into the rest of the system. The arteries deliver oxygenated blood to the body as the pump action of the heart forces the blood into the arterioles and capillaries that are located in our extremities. The veins then return the deoxygenated blood and blood that has picked up waste ...

The cardiovascular system (CVS) includes both the heart, i.e. endocardium, myocardium and pericardium, and vessels. Biopsies from these organs are relatively uncommon, and most cases actually originate from autopsies. Disease spectrum ranges from inflammatory, ischaemic and degenerative with a handful of primary and metastatic neoplasms involving the heart. Various distinct types of vasculopathies are also sometimes seen in clinical practice. In this chapter, morphological features on light microscopy and utility of special and immunohistochemical (IHC) stains, which are helpful in the workup of these lesions, are described in a compact fashion.
