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.

This book combines fundamental concepts of biochemistry and the dental sciences to provide an authentic, coherent and comprehensive text for dental students. It describes in simple language the intricate pathophysiology of biomolecules in health and in diseases of dental and oral tissues. This book also describes the evolution of biochemistry in a chronological order, provides information about the fundamental chemical structure, classification and biological significance of biomolecules, vitamins and hormones, enriched with flow charts and diagrams for easy understanding and quick reference. It includes chapters on nucleic acids, nutrition and serum enzymes and organ function tests, and offers an innovative approach to familiarize dental students with the biochemical composition of enamel, dentine, cementum and saliva, explaining the biochemical basis of dental caries, periodontal diseases, role of fluorides in caries prophylaxis, fluoride toxicity, and the role of amino acids as anti-hypersensitive agents.

“Infogest” (Improving Health Properties of Food by Sharing our Knowledge on the Digestive Process) is an EU COST action/network in the domain of Food and Agriculture that will last for 4 years from April 4, 2011. Infogest aims at building an open international network of institutes undertaking multidisciplinary basic research on food digestion gathering scientists from different origins (food scientists, gut physiologists, nutritionists...). The network gathers 70 partners from academia, corresponding to a total of 29 countries. The three main scientific goals are: Identify the beneficial food components released in the gut during digestion; Support the effect of beneficial food components on human health; Promote harmonization of currently used digestion models Infogest meetings highlighted the need for a publication that would provide researchers with an insight into the advantages and disadvantages associated with the use of respective in vitro and ex vivo assays to evaluate the effects of foods and food bioactives on health. Such assays are particularly important in situations where a large number of foods/bioactives need to be screened rapidly and in a cost effective manner in order to ultimately identify lead foods/bioactives that can be the subject of in vivo assays. The book is an asset to researchers wishing to study the health benefits of their foods and food bioactives of interest and highlights which in vitro/ex vivo assays are of greatest relevance to their goals, what sort of outputs/data can be generated and, as noted above, highlight the strengths and weaknesses of the various assays. It is also an important resource for undergraduate students in the ‘food and health’ arena.

Provides researchers, medical personnel, nutrition students, and others with an up-to-date view of several aspects of fat digestion and absorption and describes potential and realized applications. Topics addressed include enzymatic aspects of fat digestion in the gastrointestinal tract; the uptake of fat digestion products in the brush border membrane, the intracellular transport, and incorporation of these substances in glycerolipids and chylomicrons, or their portal transport; methods used to evaluate fat absorption; the effects of the triglyceride structure on fat digestion and absorption; an overview of fat absorption and studies related to malabsorption due to pancreatic and bile acid deficiency states; the effects of simulated household heating on fat absorption; and the reduction of fat uptake, either by feeding unabsorbable food fats or by interference with the digestion process of usual food fats by pharmacological means.

This second volume of Defining Physiology: Principles, Themes, Concepts. continues on the same format as the first. In this new release, a selection of 44 essential topics in each major organ system is defined, then major themes, concept and principles surrounding these words in their physiologic scenarios are elaborated. For each keyword, a question is posed at the end of the text to test for a better understanding of the associated physiology of nervous and gastrointestinal systems. This book presents an easy reference guide for those just starting out in the area of physiology and for those who are interested in clear and succinct definitions of key terms.

The physiological or psychological stresses that employees bring to their workplace affect not only their own performance but that of their co-workers and others. These stresses are often compounded by those of the job itself. Medical personnel, firefighters, police, and military personnel in combat settingsâ€"among othersâ€"experience highly unpredictable timing and types of stressors. This book reviews and comments on the performance-enhancing potential of specific food components. It reflects the views of military and non-military scientists from such fields as neuroscience, nutrition, physiology, various medical specialties, and performance psychology on the most up-to-date research available on physical and mental performance enhancement in stressful conditions. Although placed within the context of military tasks, the volume will have wide-reaching implications for individuals in any job setting.

The structure of a food influences the way it is transformed during processing and digestion. This in turn has an impact on nutrient bioaccessibility (release) and digestibility, and subsequently on the physiological response and health of the individual who consumes that food. Although evidence exists on the health benefits associated with the inclusion of certain lipid-rich foods (e.g. nuts, dairy products and fish) in the diet, the mechanisms that explain the physiological effects and the long-term benefits are not well understood. Lipids in themselves have many beneficial health effects: they are a source of energy and essential fatty acids, they are structural components of cell membranes, they are required to solubilise fat soluble compounds, and they serve as precursors of hormones. In addition, the overall structure of the food containing the lipids plays a crucial role in determining health benefits, notably by influencing lipid bioaccessibility and digestibility. Bioaccessibility and digestibility of lipids from food uniquely focuses on the physico-chemical properties of lipids and lipid rich food, as well as the subsequent effects on human health. Chapters from experts in food digestion examine food structure at both the macro- and micro- levels, covering lipids from plant and animal food products. The editors have developed the book for dietitians, nutritionists, and food scientists. Clinicians and other health professionals, educators in nutrition, and others working in the food industry will also find the material relevant.
