Download or read book Regulation Digestion Nutrition Excretion written by G. A. Kerkut and published by Elsevier. This book was released on 2013-10-22 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, seven of the chapters deal with feeding and diet, which is reasonable since insects consume an estimated l5-20% of all the world's planted crops. Many insects even have a specialized larval feeding stage that usually occupies a different ecological niche to the adult and so does not compete for the adult's food stock. Other chapters describe the means by which insects maintain their water balance, nitrogen balance and temperature balance under a range of conditions. These involve regulation by hormonal and behavioural systems that are also described here. The l4 chapters are all extensively illustrated and referenced and therefore provide excellent summaries of current knowledge. They will be of great value to entomologists, zoologists and biologists in general.
Download or read book The Exocrine Pancreas written by Stephen Pandol and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Without the exocrine pancreas, malabsorption and malnutrition result. This chapter describes the cellular participants responsible for the secretion of digestive enzymes and fluid that in combination provide a pancreatic secretion that accomplishes the digestive functions of the gland. Key cellular participants, the acinar cell and the duct cell, are responsible for digestive enzyme and fluid secretion, respectively, of the exocrine pancreas. This chapter describes the neurohumoral pathways that mediate the pancreatic response to a meal as well as details of the cellular mechanisms that are necessary for the organ responses, including protein synthesis and transport and ion transports, and the regulation of these responses by intracellular signaling systems. Examples of pancreatic diseases resulting from dysfunction in cellular mechanisms provide emphasis of the importance of the normal physiologic mechanisms.

Download or read book Regulatory Mechanisms in Insect Feeding written by Reg F. Chapman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: The only book to deal comprehensively with insect feeding was published by C. T. Brues in 1946. His Insect Dietary was an account of insect feeding habits. Since that time there has been a revolution in biology, and almost all aspects of our understanding of insect feeding have expanded to an extent and into areas that would have been unthinkable in Brues' day. Yet, our book does not replace Insect Dietary but, instead, complements it, because our aim is to bring together information on the mechanisms by which food quality and quantity are regulated. We deliberately focus attention on the feeding process; to include food-finding would have required a much larger book and would have moved the focus away from more proximate mechanisms. This book is dedicated to the late Vincent G. Dethier. As a pioneer in studying the physiological basis of animal behavior, he focused on regulation of feeding in flies and caterpillars. His work on the blowfly, together with that by his many students and co-workers, still provides the most completely described mechanism of insect feeding. The citation of his work in almost every chapter in this book illustrates the importance of his findings and ideas to our current understanding of regulation of insect feeding. The authors in this book provide many innovative and stimulating ideas typifying Dethier's approach to the study of feeding be havior.

The major themes of metabolism, proteins and nucleic acids, and biochemical events in the nervous system each have several chapters devoted to them, but specific topics such as pigments, toxins, and aging are also covered in detail. This extensive volume is therefore an invaluable source of information not only for entomologists but also for all scientists whose work involves insect biochemistry, including zoologists, biochemists, and molecular biologists and geneticists.
Download or read book Endocrinology II written by G. A. Kerkut and published by Elsevier. This book was released on 2013-10-22 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endocrinology II concerns the actions of hormones in insects, complementing Volume 7 which is concerned with the production and chemistry of insect hormones. While the preceding volume is directed mainly towards the insect endocrinologist, this volume has much of intrinsic interest to the general physiologist. It deals with the regulation of metabolism, reproduction, cuticle properties, and certain aspects of behaviour from a systems point of view and amply documents how hormones have provided basic insights into the functioning of such systems. Interference in endocrine regulation could provide future systems for insect control and this volume will provide the foundation on which the future formulation of these strategies is based. More information on diverse aspects of insect hormone action is brought together here than in any previous single work and this volume will therefore be a valuable reference source for many years to come.

Download or read book Neural Control of Gastrointestinal Function written by David Grundy and published by Morgan & Claypool Publishers. This book was released on 2011-12 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: The gastrointestinal tract is a long, muscular tube responsible for the digestion of food, assimilation of nutrients and elimination of waste. This is achieved by secretion of digestive enzymes and absorption from the intestinal lumen, with different regions playing specific roles in the processing of specific nutrients. These regions come into play sequentially as ingested material is moved along the length of the GI tract by contractions of the muscle layers. In some regions like the oesophagus transit it rapid and measured in seconds while in others like the colon transit is measured in hours and even days, commensurate with the relative slow fermentation that takes place in the large bowel. An hierarchy of controls, neural and endocrine, serve to regulate the various cellular targets that exist in the gut wall. These include muscle cells for contraction and epithelial cells for secretion and absorption. However, there are complex interactions between these digestive mechanisms and other mechanisms that regulate blood flow, immune function, endocrine secretion and food intake. These ensure a fine balance between the ostensibly conflicting tasks of digestion and absorption and protection from potentially harmful ingested materials. They match assimilation of nutrients with hunger and satiety and they ensure that regions of the GI tract that are meters apart work together in a coordinated fashion to match these diverse functions to the digestive needs of the individual. This ebook will provide an overview of the neural mechanisms that control gastrointestinal function.

Download or read book Nanotechnology and Functional Foods written by Cristina Sabliov and published by John Wiley & Sons. This book was released on 2015-04-21 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continued advancement in the sciences of functional foods and nutraceuticals has clearly established a strong correlation between consumption of bioactives and improved human health and performance. However, the efficacy and bioavailability of these bioactive ingredients (e.g., omega-3 oils, carotenoid antioxidants, vitamins, and probiotic bacteria) in foods often remains a challenge, due to their instability in food products and gastrointestinal tract, as well as their limited bioavailability. In some cases, these bioactive ingredients may impart an undesirable organoleptic characteristic to the final product, which hinders acceptance by consumers. In addressing these challenges, development of effective delivery systems is critical to meet the consumer needs for effective bioactives. The scientific knowledge behind developing effective delivery of bioactive components into modern and wide-ranging food products will be essential to reap their health-promoting benefits and to support the sustained growth of the functional foods market. Nanotechnology and Functional Foods: Effective Delivery of Bioactive Ingredients explores the current data on all aspects of nanoscale packing, carrying and delivery mechanisms of bioactives ingredients to functional foods. The book presents various delivery systems (including nano-emulsions, solid lipid nanoparticles, and polymeric nano-particles), their properties and interactions with other food components, and fate in the human body. Later chapters emphasize the importance of consumers attitude towards nano-delivery for the success of the technology and investigate the challenges faced by regulatory agencies to control risks and harmonize approaches worldwide. The wide applicability of bioactive delivery systems with the purpose of improving food quality, food safety and human health will make this book a worthy reference for a diverse range of readers in industry, research and academia.
