Pages : 511

Book Description
Lipoprotein Kinetics and Modeling contains some of the papers presented at a conference on the analysis and modeling of lipoprotein kinetic data held in Phoenix, Arizona. Contributions from both theorists and experimentalists who attended the conference focus on the developments in the use of mathematical modeling in analyzing the lipoprotein kinetics. The conference highlights the role of kinetic modeling in elucidating the dynamic processes involved in lipoprotein metabolism, the result of improper data analysis that can lead to erroneous physiological interpretations, and the emerging complexities in the lipoprotein system. Organized into six sections comprised of 37 chapters, this book begins with an overview of the theory and applications of kinetic analysis and modeling to lipoproteins. It then discusses the role of kinetic modeling in physiology, the kinetics of apoprotein B in humans, the use of kinetics in investigating the metabolism of very low and intermediate-density lipoproteins, and the models of plasma lipoprotein triglyceride kinetics. It explains the cholesterol kinetics and modeling, the kinetics of high density lipoprotein metabolism in humans, and various techniques for the analysis and modeling of lipoprotein kinetic data such as KABIS (kinetic analysis by interactive simulation) and CONSAM (conversational version of the SAAM modeling program). This book will be of interest to biologists, physiologists, clinical researchers and experts in computer technology and mathematics.

Book Description
The past two decades have seen steady progress in our understanding of the pathogenesis of atherosclerosis. The role of low density lipoprotein (LOL) increase and of LOL receptor deficiency or malfunctions in familial hypercholesterolemia has been largely enlightened by the works of Brown and Goldstein. These authors postulated also that modification of LOL to a form recognized by the scavenger or acetyl-LOL receptor may be required for lipid loading of macrophage-derived foam cells in the lesions. A growing body of evidence suggests that oxidative modification of LOL could enhance its atherogenicity by its implication as a factor in the generation of foam cells. Thus, if the role of LOL in the pathogenesis of hypercholesterolemia was well established a great deal of information appears currently on new approaches such as the mechanisms leading to the accumulation of foam cells, the impact of LOL structural alterations, notably oxidation and the role of gene mutations of apolipoprotein Band/or LOL receptor The opening topic is devoted to these new avenues outlined in the field of hypercholesterolemia. The first part concerns the genetic aspects of atherosclerosis: mainly the genetics of apo 1 ipoprote ins , their transcriptional regulation, the amino acid mutations of the apo B gene and of the LOL receptor gene, the structural domains and the acylation sites of apoprotein B.

Book Description
Plasma lipoproteins constitute a unique macromolecular system of lipid-protein complexes responsible for the transport of lipids from their sites of origin to their sites of utilization either as metabolic fuel or as structural components of cell membranes. Although studies on the role of lipoproteins in the mechanism of lipid transport are meritorious in their own right, the ever-increasing interest in chemical and functional properties of this remarkable class of conjugated proteins stems from the impressive evidence of their direct involvement in the genesis and develop ment of atherosclerotic lesions. The initial emphasis on neutral lipids and phospholipids as the most characteristic constituents of operationally defined lipoprotein classes has shifted in recent years to their protein moieties or apolipoproteins. The discovery of a number of apolipoproteins and characterization of familial hypolipoproteinemias as apolipoprotein deficiency disorders indicated that apolipoproteins play an essential role in maintaining the structural stability and integrity of lipoprotein particles. In addition to their role in the formation of lipoproteins, apolipoproteins were shown to perform a variety of functions in metabolic conversion of lipoproteins and their interactions with cellular surfaces. Results from several laboratories have demonstrated that the chemical and metabolic heterogeneity of operationally-defined lipoprotein classes is due to the presence of several discrete lipoprotein particles with similar physical properties but different and characteristic apolipoprotein composition. Thus, the apolipoproteins have emerged not only as essential structural and functional constituents of lipoproteins but also as unique chemical markers for identifying and classifying lipoprotein particles.

Book Description
Nutrients have been recognized as essential for maximum growth, successful reproduction, and infection prevention since the 1940s; since that time, the lion's share of nutrient research has focused on defining their role in these processes. Around 1990, however, a major shift began in the way that researchers viewed some nutrients particularly the vitamins. This shift was motivated by the discovery that modest declines in vitamin nutritional status are associated with an increased risk of ill-health and disease (such as neural tube defects, heart disease, and cancer), especially in those populations or individuals who are genetically predisposed. In an effort to expand upon this new understanding of nutrient action, nutritionists are increasingly turning their focus to the mathematical modeling of nutrient kinetic data. The availability of suitably-tagged (isotope) nutrients (such as B-carotene, vitamin A, folate, among others), sensitive analytical methods to trace them in humans (mass spectrometry and accelerator mass spectrometry), and powerful software (capable of solving and manipulating differential equations efficiently and accurately), has allowed researchers to construct mathematical models aimed at characterizing the dynamic and kinetic behavior of key nutrients in vivo in humans at an unparalleled level of detail.

Pages : 98

Book Description
Complex disorders including obesity, diabetes, fatty liver disease, cardiovascular disease and cancer are results from a combination of genetic, environmental and lifestyle factors. The prevalence of such disorders has increased dramatically in the last two decades and there is an urgent need for the development of new prognostic tools for the treatment of such diseases. However, this requires a deep understanding of the underlying molecular mechanisms involved in the occurrence of the diseases. With the advances in high throughput technologies, biological components of cells can be measured with a very high resolution and these data can be used for investigating whole systems properties using a network-based approach. Systems medicine provides an integrative platform for studying the interactions between the biological components of the cell using a holistic approach and generating mechanistic explanations for the emergent systems properties. This inter-disciplinary field of study allows for understanding biological processes of cells in health and disease states, gaining new insights into what drives the appearance of the disease and finally identifying proteins and metabolites implicated in human disease. Systems medicine utilizes mathematical approaches to generate models which can be employed for designing new sets of experiments and for mapping the response of the system to perturbations quantitatively. These models as well as the developed tools can accelerate the emergence of personalized medicine which can transform the practice of medicine and offer better targets for drug development with minimum side effects.

Cholesterol Metabolism, LDL, and the LDL Receptor

Cholesterol Metabolism, LDL, and the LDL Receptor PDF Author: N Myant
Publisher: Elsevier
ISBN: 0323148875
Category : Science
Languages : en
Pages : 480

Book Description
Cholesterol Metabolism, LDL, and the LDL Receptor focuses on the cholesterol biochemistry and lipoprotein metabolism. This book is organized into 10 chapters that describe the coordinated actions of three regulated processes, namely, the intracellular synthesis of cholesterol, its esterification by ACAT, and the receptor-mediated uptake of low-density lipoprotein (LDL), for optimal level of free cholesterol. The first five chapters explore the various aspects of cholesterol biology, including discussions on the interaction of ligands with their cell-surface receptors; the role of coated pits in the endocytosis of receptor-bound ligands; and the recycling of receptors through the interior of the cell. These chapters also examine the regulation of gene expression encoding inducible proteins and the use of natural and synthetic mutations in studies of the functions of the separate domains of a multifunctional protein. A chapter describes the cloning of the apoB gene, the receptor-binding domain of apoB-100, and the unusual mode of derivation of apoB-48. Considerable chapters are devoted to LDL receptor and its pathway. The concluding chapter deals with the clinical consequences of genetic dysfunction of the LDL receptor, with particular emphasis on the diagnostic and treatment approaches of familial hypercholesterolemia that are based wholly or in part on knowledge of the LDL receptor or its gene. This book is an indispensable guide for biologists, physiologists, and clinicians who are interested in the epidemiological field of cholesterol and heart attacks.
