Available in PDF, EPUB and Kindle. Book excerpt: This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Download or read book Sensory and Metabolic Control of Energy Balance written by Wolfgang Meyerhof and published by Springer Science & Business Media. This book was released on 2010-09-24 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last two decades, the prevalence of obesity has dramatically increased in western and westernized societies. Its devastating health consequences include hypertension, cardiovascular diseases, or diabetes and make obesity the second leading cause of unnecessary deaths in the USA. As a consequence, obesity has a strong negative impact on the public health care systems. Recently emerging scienti?c insight has helped understanding obesity as a complex chronic disease with multiple causes. A multileveled gene–environment interaction appears to involve a substantial number of susceptibility genes, as well as associations with low physical activity levels and intake of high-calorie, low-cost, foods. Unfor- nately, therapeutic options to prevent or cure this disease are extremely limited, posing an extraordinary challenge for today’s biomedical research community. Obesity results from imbalanced energy metabolism leading to lipid storage. Only detailed understanding of the multiple molecular underpinnings of energy metabolism can provide the basis for future therapeutic options. Numerous aspects of obesity are currently studied, including the essential role of neural and endocrine control circuits, adaptive responses of catabolic and anabolic pathways, metabolic fuel sensors, regulation of appetite and satiation, sensory information processing, transcriptional control of metabolic processes, and the endocrine role of adipose tissue. These studies are predominantly fuelled by basic research on mammalian models or clinical studies, but these ?ndings were paralleled by important insights, which have emerged from studying invertebrate models.

Download or read book Metabolic Basis of Obesity written by Rexford S. Ahima and published by Springer Science & Business Media. This book was released on 2010-11-16 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The obesity epidemic has generated immense interest in recent years due to the wide-ranging and significant adverse health and economic consequences that surround the problem. Much attention has been focused on behaviors that lead to obesity, in particular to over consumption of energy-dense food and to sedentary lifestyle. However, obesity is an extremely complex condition with poorly defined pathogenesis. Thanks to greatly enhanced research in the area, the discovery of pathways in the brain and peripheral organs that mediate energy homeostasis has provided a framework for understanding the biological basis of obesity. Metabolic Basis of Obesity adds an important new dimension to the growing literature on obesity by offering a comprehensive review of specifically how metabolic imbalance culminates in obesity. Developed by a team of expert authors, this important title discusses the principles of energy balance, genetics of body weight regulation, hormones and adipokines, and metabolic pathways in the brain, liver, muscle and fat, to name just several of the areas covered. The book also examines the connection between obesity and diabetes, cardiovascular disease and other complications. Current and future diagnostic and treatment strategies are also reviewed. Comprehensive and timely, Metabolic Basis of Obesity is an essential reference for understanding the burgeoning problem of obesity.

Download or read book Role of Protein Kinase R in Metabolic Homeostasis written by Agnieszka Pindel and published by . This book was released on 2014 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Obesity related conditions, predominantly cardiovascular disease and diabetes constitute the most significant burden to healthcare in much of the western world. The physiological response to excess nutrients influences the health consequence of obesity. Hence regulation of cellular processes that maintain energy homeostasis, such as protein translation, are critical to the pathogenesis of metabolic disease. The Protein Kinase R (PKR) participates in cell signalling and plays a key role in the maintenance of protein translation by regulating the activity of the eukaryotic initiation factor 2-alpha (eIF2[alpha]). We hypothesized that metabolic sensing via PKR and its substrate, eIF2[alpha], would initiate a general stress response to high fat diets that then modulates obesity-related diseases. This study provides the first evidence supportive of a critical role for PKR in regulating metabolic and inflammatory responses to ameliorate diet-induced obesity and ensuing pathologies. PKR ameliorates weight gain and subcutaneous fat mass deposition in response to a high fat diet. However, the detected decrease in locomotor activity and BAT temperature in mice ablated for PKR was found to not be statistically significant. Loss of PKR also perturbs major lipid signalling pathways, resulting in augmented expression of fatty acid synthase (FASN) and diacylglycerol transferase 2 (DGAT2), both of which induce triglyceride synthesis and likely contribute to adipose tissue expansion. Indeed, mice ablated for PKR are hyperlipidemic as reflected by increased serum concentration of triglycerides, decreased concentration of low-density lipoprotein (LDL) and an unfavourable ration of high to low density lipoprotein (HDL/LDL). The consequence of this altered lipid metabolism is explored by measuring the effect of PKR deficiency on obesity associated cardiovascular disease in the apolipoprotein E (apoE) deficient mouse as a model for atherosclerosis. Ablating PKR from mice also deficient in apoE exacerbates diet-induced atherosclerosis, confirming that PKR plays a key role in disease development.We also show that PKR maintains pancreatic islet size and normal glucose homeostasis. Ablation of PKR increases expression of the gluconeogenic enzyme glucose-6-phosphatase (G6pase) in the liver accounting for increased hepatic glucose production and glucose intolerance. We also establish that PKR deficiency in vitro suppresses expression of the insulin receptor substrate 2 (IRS2) and consequently disrupts insulin signalling by reducing phosphorylation of p70S6K. In contrast to a recent report by Nakamura et al, that PKR promotes diet-induced obesity by increasing inflammation and suppressing insulin signalling by phosphorylation of IRS1, we see no PKR-dependent regulation of classic inflammatory cytokines IL-6 and TNF-[alpha]. Instead, in the absence of PKR heightens secretion of IL-1[beta] from the pancreas, which has previously been reported to associate with pancreatic islet cell damage and disturbed glucose homeostasis. The mechanism likely to explain this effect is PKR-mediated inflammasome activation; however further research is required to confirm this mode of action.Collectively these findings demonstrate that PKR is protective against diet-induced weight gain and the pathogenesis of metabolic disease. These results fit in with the principle function of PKR to relieve stress by inducing the integrated stress response.

Download or read book ATP and the Heart written by Joanne S. Ingwall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: ATP plays a central role in the two leading causes of cardiac morbidity and mortality in the western world: ischemia and heart failure. We are in our infancy applying what is known about biology and chemistry of ATP toward developing effective therapies for these diseases. In this volume, the current understanding of the chemistry and biology of ATP specifically in the cardiomyocyte is presented. New insights into ATP have been gleaned using biophysical techniques allowing dynamic measurement of chemical events in the intact beating heart and using new animal models in which cardiac proteins are either over expressed, deleted or harbor specific mutations. This book provides a summary of the basic understanding and includes illustrations of why ATP and the Heart is important to both the clinician and scientist.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
