Download or read book Cellular and Biochemical Mechanisms of Obesity written by Paramjit S. Tappia and published by Springer Nature. This book was released on 2021-12-15 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global health has been challenged with the dawning of the era of the obesity epidemic, and thus as a consequence, strategies to reduce obesity have become public health priorities. According to the United Nations, obesity has been identified as a concern for achieving Sustainable Development Goals. Obesity is a serious health problem with an increased risk of several common diseases including diabetes, cardiovascular disease, and cancer. Although the fundamental cause of obesity and overweight is an imbalance between calorie intake and calorie expenditure, the underlying biochemical and metabolic processes that cause obesity are not fully understood. Two earlier volumes dedicated to the subject of obesity, published in the series “Advances in Biochemistry in Health and Disease” focused on the pathophysiology of obesity-induced health complications and the biochemistry of cardiovascular dysfunction in obesity. This book brings together contributions from international experts in the field to describe advancements on the mechanisms leading to development of obesity and related complications. There are 21 chapters in two different parts in this book, comprising of Part I: Pathophysiologic Mechanisms of Obesity (11 chapters) and Part II: Therapeutic Mechanisms of Obesity (10 chapters). This book will serve as a resource and be of interest to health professionals, medical students, fellows, residents and graduate students. It will also evoke innovative research and effective approaches for the prevention of obesity. This volume will accentuate that obesity is a major health hazard in its own right and that appropriate public health measures should be implemented to prevent or reduce or even reverse the impact of this global chronic disease.

Available in PDF, EPUB and Kindle. Book excerpt: Obesity is a multi-factorial disease, in which an excess of accumulated body fat can reach levels capable of affecting health. It results from an interplay between environmental factors, eating behavior, genes, epigenetics, and neuronal stimuli. The main aim of this book is to provide a state-of-the-art revision about the molecular mechanisms underpinning the development of obesity, reviewing the current knowledge in areas like monogenic and polygenic obesity forms, but also providing an updated view of the emerging knowledge about epigenetics, nutrigenomics, and neuronal aspects that also contribute to obesity.
Download or read book The Adipocyte and Obesity written by Charles H. Hollenberg and published by New York : Raven Press. This book was released on 1983 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The proceedings of a 1982 international conference covers 33 review articles on research findings and the current state of knowledge of various metabolic and mechanistic aspects of the associations between the adipocyte fat cell and obesity. The articles address various facets of adipose cell growth and development; insulin action; lipid assimilation and lipoprotein and cholesterol metabolism in adipose tissue; lipolysis in adipocytes; and energy expenditure. The role of adipose tissue as a model system for the study of mechanisms of insulin action is highlighted by evidence of new cellular mediators. Recent insights in triglyceride assimilation regulation by lipoprotein lipase and fatty acid release through the lipolytic cascade are discussed. Other topics include the role of lipocytes in cholesterol turnover, the relationship of cholesterol metabolism to lipoprotein turnover and catabolism, and aspects of energy balance and thermoregulation in obesity.

Download or read book Weight Management written by Institute of Medicine and published by National Academies Press. This book was released on 2003-12-01 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of fitness and body composition standards in the U.S. Armed Forces has always been to select individuals best suited to the physical demands of military service, based on the assumption that proper body weight and composition supports good health, physical fitness, and appropriate military appearance. The current epidemic of overweight and obesity in the United States affects the military services. The pool of available recruits is reduced because of failure to meet body composition standards for entry into the services and a high percentage of individuals exceeding military weight-for-height standards at the time of entry into the service leave the military before completing their term of enlistment. To aid in developing strategies for prevention and remediation of overweight in military personnel, the U.S. Army Medical Research and Materiel Command requested the Committee on Military Nutrition Research to review the scientific evidence for: factors that influence body weight, optimal components of a weight loss and weight maintenance program, and the role of gender, age, and ethnicity in weight management.
Download or read book Molecular Aspects of the Link Between Obesity Insulin Resistance and Breast Cancer written by Michael Georg Weichhaus and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Obesity is a multi-factorial metabolic disease, resulting in increased adipose tissue acquisition by the host. This disease increases the risk for developing co-morbidities, including Metabolic Syndrome and other disorders such as breast cancer. Obesity, and particularly abdominal obesity, is characterised by metabolic changes, including chronically elevated insulin concentrations and aberrant secretion of cytokines released from fat tissue, called adipokines. Epidemiologically, the risk of developing postmenopausal breast cancer is increased in obese individuals. The molecular link between obesity and breast cancer however is not well understood. The study presented here aimed at identifying the molecular mechanisms involved in this link, by testing the hypothesis that high insulin concentration and certain adipokines may promote breast cancer progression and/or breast cancer aetiology. A cell culture system of breast cancer cells and breast epithelial cells was employed to investigate changes in cell proliferation, activation of cell signalling pathways, cell cycle progression and apoptosis after treatment with insulin, leptin, TNF-[alpha], adiponectin and IL-6. In MDA-MB-231 breast cancer cells, insulin treatment did not affect cell proliferation, cell cycle or apoptosis. Conversely, IR-phosphorylation, AKT-phosphorylation and ERK1/2-phosphorylation were all significantly increased. Microarray analysis indicated several important changes in gene expression with insulin treatment. Leptin treatment increased proliferation by 21%. Additional analyses of the effect of leptin indicated that neither the PI3-kinase pathway nor the MAP-kinase pathway was involved in mediating this effect. Treatment with TNF-[alpha] increased apoptosis, but did not affect cell proliferation or activation of cell signalling pathways. In MCF-10A breast epithelial cells, cell proliferation increased after insulin treatment by 180%. IR-phosphorylation, AKT-phosphorylation and ERK1/2 phosphorylation were all significantly increased while early apoptosis decreased after insulin treatment. Analysis of cell cycle however did not indicate a change in progression. Microarray analysis indicated that insulin treatment may increase expression of genes related to cancer growth. Leptin treatment increased cell proliferation and also increased ERK1/2-phosphorylation, while AKT-phosphorylation was not affected. Leptin did not change cell cycle progression. TNF-[alpha] treatment increased cell proliferation and also increased ERK1/2 phosphorylation, while AKT-phosphorylation was not changed. TNF-[alpha] treatment tended to increase apoptosis, the change however was not statistically significant. In SK-BR-3 breast cancer cells, cell proliferation did not change after insulin treatment. IR-phosphorylation and AKT-phosphorylation increased after insulin treatment, while ERK1/2-phosphorylation decreased. Gene expression of cyclin D and cyclin E increased with insulin treatment, while apoptotic rate and cell cycle profile were also not affected. Cell proliferation increased by 115% after treatment with 100 ng/ml leptin. ERK1/2-phosphorylation however decreased, while AKT-phosphorylation tended to increase, but the change was not statistically significant. Cell cycle profile was not affected by leptin treatment, G1-phase however tended to increase, but the change was again not statistically significant. Cell proliferation increased by 59% after 48 h treatment with 10 ng/ml TNF-[alpha]. AKT-phosphorylation and ERK1/2-phosphorylation increased with TNF-[alpha] treatment. Cell cycle analysis showed a decrease in S-phase and G2-phase, indicative of a decrease in cell cycle progression. These results indicate that none of the examined obesity-related factors is convincingly identified as the main molecular link between obesity and postmenopausal breast cancer. Conversely, all treatments affected each of the cell lines in, at least, one of the examined aspects. This indicates that many of the obesity-related factors may affect breast cancer and that a single breast tumour may utilise a unique combination of those factors to promote growth. All treatments increased proliferation in MCF-10A breast epithelial cells, with additional analysis generally supporting growth promotion. Insulin treatment particularly increased cell proliferation, while leptin and TNF-[alpha] increased MAP-kinase signalling. This may indicate that insulin and adipokines may have a higher impact on breast cancer aetiology than on breast cancer progression.

Download or read book Weighing the Options written by Institute of Medicine and published by National Academies Press. This book was released on 1995-03-01 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly one out of every three adults in America is obese and tens of millions of people in the United States are dieting at any one time. This has resulted in a weight-loss industry worth billions of dollars a year and growing. What are the long-term results of weight-loss programs? How can people sort through the many programs available and select one that is right for them? Weighing the Options strives to answer these questions. Despite widespread public concern about weight, few studies have examined the long-term results of weight-loss programs. One reason that evaluating obesity management is difficult is that no other treatment depends so much on an individual's own initiative and state of mind. Now, a distinguished group of experts assembled by the Institute of Medicine addresses this compelling issue. Weighing the Options presents criteria for evaluating treatment programs for obesity and explores what these criteria meanâ€"to health care providers, program designers, researchers, and even overweight people seeking help. In presenting its criteria the authors offer a wealth of information about weight loss: how obesity is on the rise, what types of weight-loss programs are available, how to define obesity, how well we maintain weight loss, and what approaches and practices appear to be most successful. Information about weight-loss programsâ€"their clients, staff qualifications, services, and success ratesâ€"necessary to make wise program choices is discussed in detail. The book examines how client demographics and characteristicsâ€"including health status, knowledge of weight-loss issues, and attitude toward weight and body imageâ€"affect which programs clients choose, how successful they are likely to be with their choices, and what this means for outcome measurement. Short- and long-term safety consequences of weight loss are discussed as well as clinical assessment of individual patients. The authors document the health risks of being overweight, summarizing data indicating that even a small weight loss reduces the risk of disease and depression and increases self-esteem. At the same time, weight loss has been associated with some poor outcomes, and the book discusses the implications for program evaluation. Prevention can be even more important than treatment. In Weighing the Options, programs for population groups, efforts targeted to specific groups at high risk for obesity, and prevention of further weight gain in obese individuals get special attention. This book provides detailed guidance on how the weight-loss industry can improve its programs to help people be more successful at long-term weight loss. And it provides consumers with tips on selecting a program that will improve their chances of permanently losing excess weight.
