Available in PDF, EPUB and Kindle. Book excerpt: To a number of physiological and pathological human conditions, there are a variety of natural animal models that can be studied in an effort to obtain greater knowledge and insight into the progression of the disease, as well as enable more accurate and successful therapeutic strategies. The northern elephant seal, specifically the fasting pups, have been established as a powerful, natural model for a number of human diseases, including the onset and development of insulin resistance. Thyroidal regulation has been implicated to change or be changed during the progression of the disease. Therefore, the aim of this dissertation is to elucidate how the two are regulating one another, and specifically what the contributions of an active thyroidal system are, to the regulation of substrate metabolism, especially lipid. In the first chapter, we demonstrated that despite a prolonged fasting period, northern elephant seal pups do not down-regulate thyroid hormone-mediated events, but rather increase all components that would result in increased cellular metabolism. In the second chapter we showed that fasting duration increases the sensitivity of adipose TH-mediated mechanisms to insulin, some of which may be mediated by increased glucose. The third chapter underscored the physiological relevance of an increased thyroidal status, which very clearly is substantially up-regulated with fasting duration, as the thyroid gland evidently increases its production of thyroid hormones with fasting duration. The fourth chapter reveals the contribution of this perplexing physiological response to fasting and its capacity to not only drive lipid metabolism but also lead the system into a necessary state of insulin resistance. Evolution has led some species to develop unique adaptations to environmental influences and lifestyles that are fascinating, perplexing and, if only understood, bare solutions to widespread health issues. Elephant seals are such a species. Despite prolonged fasting their metabolism neither slows down nor reduces its sensitivity to stimulation, as is common, to avoid resource depletion. Instead we find the opposite. Increased thyroid hormone levels and dynamic response to thyroid gland stimulation reveal how the seals thrive on a fasting-driven body fat diet. These studies have the potential to elucidate new therapeutic targets for hormone treatment of human obesity and related metabolic dysfunctions.

Download or read book Comparative Physiology of Fasting Starvation and Food Limitation written by Marshall D. McCue and published by Springer Science & Business Media. This book was released on 2012-05-17 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: All animals face the possibility of food limitation and ultimately starvation-induced mortality. This book summarizes state of the art of starvation biology from the ecological causes of food limitation to the physiological and evolutionary consequences of prolonged fasting. It is written for an audience with an understanding of general principles in animal physiology, yet offers a level of analysis and interpretation that will engage seasoned scientists. Each chapter is written by active researchers in the field of comparative physiology and draws on the primary literature of starvation both in nature and the laboratory. The chapters are organized among broad taxonomic categories, such as protists, arthropods, fishes, reptiles, birds, and flying, aquatic, and terrestrial mammals including humans; particularly well-studied animal models, e.g. endotherms are further organized by experimental approaches, such as analyses of blood metabolites, stable isotopes, thermobiology, and modeling of body composition.

Available in PDF, EPUB and Kindle. Book excerpt: Taking an integrated approach to the biology of marine carnivores, cetaceans, and sirenians, twenty-two prominent researchers compare marine mammals with one another and with terrestrial mammals, providing a framework for fundamental biological and ecological concepts. They describe functional morphology, sensory systems, energetics, reproduction, communication and cognition, behavior, distribution, population biology, and feeding ecology. They also detail the physiological adaptations—for such activities and processes as diving, thermo-regulation, osmoregulation, and orientation—that enable marine mammals to exploit their aquatic environment.
