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.

This book was released on 2011-08-03 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proteases are everywhere from prokaryotes to eukaryotes, from virus to bacteria and in all human tissues, playing a role in many biological functions. Among these functions, the inflammatory reaction is of particular interest. In inflamed tissues, proteases can have a microbial and/or host origin and are involved not only in tissue remodeling, but also in specific signaling to resident or inflammatory cells, thereby contributing to the innate immune response. This volume presents all advances in our knowledge of the role proteases and their inhibitors play in various diseases associated with inflammatory response. Mechanisms involved in protease signaling to cells are presented, and the different types of proteases that are present at inflammatory sites and their effects on the course of inflammation are discussed. Finally, the evidence for considering proteases and their receptors as potential molecular targets for therapeutic interventions in the treatment of inflammatory diseases is discussed in the context of specific organ inflammatory pathologies (the lung, gastrointestinal tract, skin, joints, etc.).

This book was released on 2018 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crohn's disease (CD) and Ulcerative colitis (UC) are two forms of Inflammatory Bowel Disease (IBD), a chronic inflammatory pathology affecting the digestive tract. Patients suffer from relapsing flares, diarrhea, abdominal pain and bleeding. Although the molecular mechanisms of IBD are poorly understood, recent data suggest that IBD occurs in genetically predisposed individuals developing an abnormal immune response to intestinal microbes after, being exposed to specific environmental triggers. Genetic studies have reported more than 170 polymorphisms susceptible to be involved in IBD pathogenesis. The strongest associations have highlighted three main pathways altered in IBD including bacterial sensing (NOD2, CD), autophagy (ATG16L1 and IRGM, CD) and endoplasmic reticulum stress (ER-Stress) (XBP1, UC). The role of intestinal barrier function is also strongly implicated in IBD pathogenesis, and is modulated by factors present in the lumen derived from microbiota, food or at a molecular level, by factors such as proteases. In IBD pathophysiology, the inflammatory process is characterized by impaired intestinal biology including disruption of tight junctions and leaky gut, decreased amount of Paneth and Goblet cells, and translocation of luminal antigens triggering inflammation. Previous studies have demonstrated an increased level of active serine proteases in the stools and tissues of IBD patients, supposing that proteases originate from infiltrated immune cells, pancreatic secretion or microbiota. However, our team has reported that intestinal epithelial cells are a major source of serine proteases, in particular trypsin-like enzymes, are released by a stressed epithelium in pathogenic context such as irritable bowel syndrome. In this project, we aimed at better understanding whether the three main pathways involved in IBD (Nod2, autophagy, ER-stress) could be linked to an epithelial release of trypsin and reciprocally, if epithelial trypsin is able to induce or modulate these three IBD pathways. We confirmed that trypsin-like activity was significantly higher in biopsies from UC and CD patients compared to healthy controls. In Caco-2 monolayers cultured in transwells, secreted trypsin-like proteolytic activity remained stable upon NOD2 stimulation but decreased under autophagy induction. Thapsigargin (Tg) stimulation a well-known ER-stress inducer, enhanced the apical release of trypsin-like activity in Caco2 cells. [...].

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Proteolytic Enzymes, Second Edition, Volume 1: Aspartic and Metallo Peptidases is a compilation of numerous progressive research studies on proteolytic enzymes. This edition is organized into two main sections encompassing 328 chapters. This handbook is organized around a system for the classification of peptidases, which is a hierarchical one built on the concepts of catalytic type, clan, family and peptidase. The concept of catalytic type of a peptidase depends upon the chemical nature of the groups responsible for catalysis. The recognized catalytic types are aspartic, cysteine, metallo, serine, threonine, and the unclassified enzymes, while clans and families are groups of homologous peptidases. Homology at the level of a family of peptidases is shown by statistically significant relationship in amino acid sequence to a representative member called the type example, or to another member of the family that has already been shown to be related to the type example. Each chapter discusses the history, activity, specificity, structural chemistry, preparation, and biological aspects of the enzyme. This book will prove useful to enzyme chemists and researchers.

Book excerpt: A Comprehensive Guide to Crucial Attributes of Therapeutic Proteins in Biological Pharmaceuticals With this book, Dr. Raju offers a valuable resource for professionals involved in research and development of biopharmaceutical and biosimilar drugs. This is a highly relevant work, as medical practitioners have increasingly turned to biopharmaceutical medicines in their search for safe and reliable treatments for complex diseases, while pharmaceutical researchers seek to expand the availability of biopharmaceuticals and create more affordable biosimilar alternatives. Readers receive a thorough overview of the major co-translational modifications (CTMs) and post-translational modifications (PTMs) of therapeutic proteins relevant to the development of biotherapeutics. The majority of chapters detail individual CTMs and PTMs that may affect the physicochemical, biochemical, biological, pharmacokinetic, immunological, toxicological etc. properties of proteins. In addition, readers are guided on the methodology necessary to analyze and characterize these modifications. Thus, readers gain not only an understanding of CTMs/PTMs, but also the ability to design and assess their own structure-function studies for experimental molecules. Specific features and topics include: Discussion of the research behind and expansion of biopharmaceuticals Twenty chapters detailing relevant CTMs and PTMs of proteins, such as glycosylation, oxidation, phosphorylation, methylation, proteolysis, etc. Each chapter offers an introduction and guide to the mechanisms and biological significance of an individual CTM or PTM, including practical guidance for experiment design and analysis An appendix of biologic pharmaceuticals currently on the market, along with an assessment of their PTMs and overall safety and efficacy This volume will prove a key reference on the shelves of industry and academic researchers involved in the study and development of biochemistry, molecular biology, biopharmaceuticals and proteins in medicine, particularly as biopharmaceuticals and biosimilars become ever more prominent tools in the field of healthcare.

Available in PDF, EPUB and Kindle. Book excerpt: The microcirculation of the gastrointestinal tract is under the control of both myogenic and metabolic regulatory systems. The myogenic mechanism contributes to basal vascular tone and the regulation of transmural pressure, while the metabolic mechanism is responsible for maintaining an appropriate balance between O2 demand and O2 delivery. In the postprandial state, hydrolytic products of food digestion elicit a hyperemia, which serves to meet the increased O2 demand of nutrient assimilation. Metabolically linked factors (e.g., tissue pO2, adenosine) are primarily responsible for this functional hyperemia. The fenestrated capillaries of the gastrointestinal mucosa are relatively permeable to small hydrolytic products of food digestion (e.g., glucose), yet restrict the transcapillary movement of larger molecules (e.g., albumin). This allows for the absorption of hydrolytic products of food digestion without compromising the oncotic pressure gradient governing transcapillary fluid movement and edema formation. The gastrointestinal microcirculation is also an important component of the mucosal defense system whose function is to prevent (and rapidly repair) inadvertent epithelial injury by potentially noxious constituents of chyme. Two pathological conditions in which the gastrointestinal circulation plays an important role are ischemia/reperfusion and chronic portal hypertension. Ischemia/reperfusion results in mucosal edema and disruption of the epithelium due, in part, to an inflammatory response (e.g., increase in capillary permeability to macromolecules and neutrophil infiltration). Chronic portal hypertension results in an increase in gastrointestinal blood flow due to an imbalance in vasodilator and vasoconstrictor influences on the microcirculation.

This book was released on 2019-11-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Increasing evidence suggests that microbiota and especially the gut microbiota (the microbes inhabiting the gut including bacteria, archaea, viruses, and fungi) plays a key role in human physiology and pathology. Recent findings indicate how dysbiosis—an imbalance in the composition and organization of microbial populations—could severely impact the development of different medical conditions (from metabolic to mood disorders), providing new insights into the comprehension of diverse diseases, such as IBD, obesity, asthma, autism, stroke, diabetes, and cancer. Given that microbial cells in the gut outnumber host cells, microbiota influences human physiology both functionally and structurally. Microbial metabolites bridge various—even distant—areas of the organism by way of the immune and hormone system. For instance, it is now clear that the mutual interaction between the gastrointestinal tract and the brain (gut–brain axis), often involves gut microbiota, indicating that the crosstalk between the organism and its microbial residents represents a fundamental aspect of both the establishment and maintenance of healthy conditions. Moreover, it is crucial to recognize that beyond the intestinal tract, microbiota populates other host organs and tissues (e.g., skin and oral mucosa). We have edited this eBook with the aim of publishing manuscripts focusing on the impact of microbiota in the development of different diseases and their associated treatments.]

Book excerpt: Why is eating food in its natural state, unprocessed and unrefined, so vital to the maintenance of good health? What is lacking in our modern diet that makes us so susceptible to degenerative disease? What natural elements in food may play a key role in unlocking the secrets of life extension? These fascinating questions, and many more, are answered in Enzyme Nutrition. Written by one of America’s pioneering biochemists and nutrition researchers, Dr. Edward Howell, Enzyme Nutrition presents the most vital nutritional discovery since that of vitamins and minerals—food enzymes. Our digestive organs produce some enzymes internally, however food enzymes are necessary for optimal health and must come from uncooked foods such as fresh fruits and vegetables, raw sprouted grains, unpasteurized dairy products, and food enzyme supplements. Enzyme Nutrition represents more than fifty years of research and experimentation by Dr. Howell. He shows us how to conserve our enzymes and maintain internal balance. As the body regains its strength and vigor, its capacity to maintain its normal weight, fight disease, and heal itself is enhanced.

Available in PDF, EPUB and Kindle. Book excerpt: This reference work provides comprehensive information about the bioactive molecules presented in our daily food and their effect on the physical and mental state of our body. Although the concept of functional food is new, the consumption of selected food to attain a specific effect existed already in ancient civilizations, namely of China and India. Consumers are now more attentive to food quality, safety and health benefits, and the food industry is led to develop processed- and packaged-food, particularly in terms of calories, quality, nutritional value and bioactive molecules. This book covers the entire range of bioactive molecules presented in daily food, such as carbohydrates, proteins, lipids, isoflavonoids, carotenoids, vitamin C, polyphenols, bioactive molecules presented in wine, beer and cider. Concepts like French paradox, Mediterranean diet, healthy diet of eating fruits and vegetables, vegan and vegetarian diet, functional foods are described with suitable case studies. Readers will also discover a very timely compilation of methods for bioactive molecules analysis. Written by highly renowned scientists of the field, this reference work appeals to a wide readership, from graduate students, scholars, researchers in the field of botany, agriculture, pharmacy, biotechnology and food industry to those involved in manufacturing, processing and marketing of value-added food products.
