Lipid metabolism in the normoxic and ischaemic heart


Book Description

Scientific progress with respect to the important role of various lipids in myocardial function and the dearrangements of lipid metabolism underlying ischaemic heart disease(s) has been con siderable in recent years. In 1986 alone, an overall number ofl 044 full papers covering the topics "Lipids-Heart-Heart Disease", have been published in a variety of biochemistry, physiology, pharmacology and cardiology journals (source: Index Medicus). They have broadened our in sight into the molecular basis of myocardial lipidology and the lipido-chemical basis of car diology in health and disease, and have narrowed the gap between promising pharmacological intervention in experimental animals and clinical treatment of patients suffering from an ischaemic heart. Furthermore, they illustrate the fundamental significance of the product of the union between basic and clinical science. The rapid development of knowledge in the "Lipids-Heart-Heart Disease" triad prompted us to organize the International Symposium on Lipid Metabolism in the Normoxic and lschaemic Heart, held in Rotterdam (The Netherlands) on September 22 and 23, 1986. This meeting was a coproject of the Department of Biochemistry I (Medical Faculty, Erasmus University Rotter dam) and the Department of Physiology (Medical Faculty, University of Limburg) and was held under the auspices of the GerritJan Mulder Foundation (named after a famous Rotterdam physi cian and chemist who lived from 1802-1880) whom we thank for their co-operation. The present volume is a compendium of invited papers and contributions selected from the posters presented during the symposium.




Lipid Metabolism in Normoxic and Ischemic Heart


Book Description

During recent decades, bewildering progress has occurred in the field of Molecular and Cellular Biochemistry. Progress has been extraordinarily rapid primarily because of the challenge for finding solutions to a wide variety of diseases and the availability of new techniques for monitoring biochemical processes. This has resulted in a voluminous and complex literature in the field of biochemical medicine so that there is a clear need for the synthesis and analysis of the continuing expansion of valuable data. It was thus considered appropriate to initiate a new series of monographs, each dedicated to a specialized area of investigation, encompassing molecular and cellular processes in health and disease. Most of the biochemical scientists have devoted their energies in understanding the fundamentals of biochemistry and indeed impressive advances have been made in the past. However, the full potential for explanation has been hampered by the concept of universality of biochemical reactions occurring in the cell. In view of the fact that each organ in the body performs a distinct function, it is now beginning to be realized that each cell type is unique in its need to survive and perform its specific function. Accordingly, the aspect of individualty is receiving increased attention for revealing new avenues in the study of pathophysiology of cellular abnormalities.

Cardiac Metabolism in Health and Disease


Book Description

This special issue of Molecular and Cellular Biochemistry contains original research papers as well as invited reviews focused in the field of cardiac metabolism and its regulation under normal and disease conditions. These papers cover many areas under intensive and rapid development such as the regulation of fatty acid oxidation in the heart, the role of cardiac glycogen during ischemia, the role of CPT I isoenzymes, the pathophysiology of diabetic cardiomyopathy, cardiac protection through regulation of energy production, the role of fatty acid binding protein under normal and pathological conditions, and several other important topics in this area of research. We hope that this special issue of Molecular and Cellular Biochemistry provides an up-to-date source of information for scientists and clinicians interested in the mechanism by which cardiac metabolism is regulated in health and disease and the mechanistic relationship between disturbances in cardiac metabolism and the genesis of cardiovascular diseases.

Biochemistry of Diabetes and Atherosclerosis


Book Description

Diabetes is an autoimmune, inflammatory disease affecting many different organ systems and exhibiting both primary and secondary defects. Because diabetes affects a wide range of cellular systems, a multidisciplinary effort has been mounted over the past several decades using a wide range of investigative techniques and methodologies in order to identify molecular mechanisms responsible for cellular dysfunction. Because primary defects at various levels of sub-cellular signaling, intracellular calcium handling, protein expression and energy regulation are often a primary consequence of diabetes. This volume is a compilation of new multidisciplinary research that will broaden our current understanding of diabetes and cardiovascular disease as well as provide the basis for the development of novel therapeutic interventions.




Regulation of Coronary Blood Flow


Book Description

Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.




Cardiac Energy Metabolism in Health and Disease


Book Description

The heart has a very high energy demand but very little energy reserves. In order to sustain contractile function, the heart has to continually produce a large amount of ATP. The heart utilizes free fatty acids mainly and carbohydrates to some extent as substrates for making energy and any change in this energy supply can seriously compromise cardiac function. It has emerged that alterations in cardiac energy metabolism are a major contributor to the development of a number of different forms of heart disease. It is also now known that optimizing energy metabolism in the heart is a viable and important approach to treating various forms of heart disease. Cardiac Energy Metabolism in Health and Disease describes the research advances that have been made in understanding what controls cardiac energy metabolism at molecular, transcriptional and physiological levels. It also describes how alterations in energy metabolism contribute to the development of heart dysfunction and how optimization of energy metabolism can be used to treat heart disease. The topics covered include a discussion of the effects of myocardial ischemia, diabetes, obesity, hypertrophy, heart failure, and genetic disorders of mitochondrial oxidative metabolism on cardiac energetics. The treatment of heart disease by optimizing energy metabolism is also discussed, which includes increasing overall energy production as well as increasing the efficiency of energy production and switching energy substrate preference of the heart. This book will be a valuable source of information to graduate students, postdoctoral fellows, and investigators in the field of experimental cardiology as well as biochemists, physiologists, pharmacologists, cardiologists, cardiovascular surgeons and other health professionals.




Regulation of Tissue Oxygenation, Second Edition


Book Description

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.
