Book Description
The 21st century has witnessed a complete revolution in the understanding and description of bacteria in eco- systems and microbial assemblages, and how they are regulated by complex interactions among microbes, hosts, and environments. The human organism is no longer considered a monolithic assembly of tissues, but is instead a true ecosystem composed of human cells, bacteria, fungi, algae, and viruses. As such, humans are not unlike other complex ecosystems containing microbial assemblages observed in the marine and earth environments. They all share a basic functional principle: Chemical communication is the universal language that allows such groups to properly function together. These chemical networks regulate interactions like metabolic exchange, antibiosis and symbiosis, and communication. The National Academies of Sciences, Engineering, and Medicine's Chemical Sciences Roundtable organized a series of four seminars in the autumn of 2016 to explore the current advances, opportunities, and challenges toward unveiling this "chemical dark matter" and its role in the regulation and function of different ecosystems. The first three focused on specific ecosystemsâ€"earth, marine, and humanâ€"and the last on all microbiome systems. This publication summarizes the presentations and discussions from the seminars.

Book Description
7 If so, the individual members of each class thus identified could then be subjected to a more profound pharmacokinetic analysis. In other words, we had to determine first which hormone protects against which drug, before we could explore how it did this. We had to know first that a hormone has adaptive value before we could ask whether this is due to a syntoxic or a catatoxic mechanism. Such observations, as the fact that an indomethacin-induced intestinal ulcer can be prevented by ethylestrenol, orthat cortisol aggravates certain infections, reveal nothing about how these hormones work; but only findings of this type can tell us where further research would be rewarding. Of course, scientists can rarely identify by direct observation the tbings that they are looking for; most of the time they have to be guided by indirect indices. The ebernist often first detects a compound, or even a particular functional group in its molecule, by inference from a color reaction, a revealing X-ray diffraction pattern or the formation of a characteristic precipitate. The physician must first suspect the presence of a microbe through certain clinical signs and symptoms before he can verify his diagnosis by looking for a particular organism. It is perhaps not too daring to hope that in our first efforts to clarify the role of hormones in resistance, simple, directly visible indicators might also serve us best.

Book Description
Drawing on expert opinions from the fields of nutrition, gut microbiology, mammalian physiology, and immunology, Diet-Microbe Interactions for Human Health investigates the evidence for a unified disease mechanism working through the gut and its resident microbiota, and linking many inflammation-related chronic diet associated diseases. State of the art post-genomic studies can highlight the important role played by our resident intestinal microbiota in determining human health and disease. Many chronic human diseases associated with modern lifestyles and diets — including those localized to the intestinal tract like inflammatory bowel disease and celiac disease, and more pervasive systemic conditions such as obesity, diabetes and cardiovascular disease — are characterized by aberrant profiles of gut bacteria or their metabolites. Many of these diseases have an inflammatory basis, often presenting with a chronic low-grade systemic inflammation, hinting at persistent and inappropriate activation of inflammatory pathways. Through the presentation and analysis of recent nutrition studies, this book discusses the possible mechanisms underpinning the disease processes associated with these pathologies, with high fat diets appearing to predispose to disease, and biologically active plant components, mainly fiber and polyphenols, appearing to reduce the risk of chronic disease development. - One comprehensive, translational source for all aspects of nutrition and diet's effect on gastrointestinal health and disease - Experts in nutrition, diet, microbiology and immunology take readers from the bench research (cellular and biochemical mechanisms of vitamins and nutrients) to new preventive and therapeutic approaches - Clear presentations by leading researchers of the cellular mechanisms underlying diet, immune response, and gastrointestinal disease help practicing nutritionists and clinicians (gastroenterologists, endocrinologists) map out new areas for clinical research and structuring clinical recommendations

Book Description
A great number of diverse microorganisms inhabit the human body and are collectively referred to as the human microbiome. Until recently, the role of the human microbiome in maintaining human health was not fully appreciated. Today, however, research is beginning to elucidate associations between perturbations in the human microbiome and human disease and the factors that might be responsible for the perturbations. Studies have indicated that the human microbiome could be affected by environmental chemicals or could modulate exposure to environmental chemicals. Environmental Chemicals, the Human Microbiome, and Health Risk presents a research strategy to improve our understanding of the interactions between environmental chemicals and the human microbiome and the implications of those interactions for human health risk. This report identifies barriers to such research and opportunities for collaboration, highlights key aspects of the human microbiome and its relation to health, describes potential interactions between environmental chemicals and the human microbiome, reviews the risk-assessment framework and reasons for incorporating chemicalâ€"microbiome interactions.

Book Description
Presents recent research on metabolism and the health effects of polyphenols Consumer interest in the health benefits of many phenolic compounds found in plant foods and derivatives has grown considerably in recent years, giving rise to an increased demand for functional foods. Although preclinical and observational studies have promoted the protective properties of polyphenols for a range of chronic diseases, evidence has shown that most dietary polyphenols have little bioavailability. Once ingested, most of them are metabolized by either the intestinal enzymes or by the gut microbiota and then undergo extensive phase-II metabolism reaching significant concentrations of conjugated metabolites. They remain in the systemic circulation and target systemic tissues where trigger biological effects. The polyphenol-derived metabolites produced in humans are dependent upon the composition of the gut microbiota and the subject genetics. Thus all the metabolites do not show the same biological activity in different individuals. To fully understand the health effects of polyphenols, further clinical investigations are required. Dietary Polyphenols describes the latest findings on the polyphenol metabolism and reviews the current evidence on their health effects and that of their bioavailable metabolites. Emphasizing the importance of interindividual variability and the critical role of gut microbiota, this authoritative volume features contributions from recognized experts in the field, exploring specific families of extractable and non-extractable phenolic compounds that exhibit potential health effects. Topics include structural diversity of polyphenols and distribution in foods, bioavailability and bioaccessibility of phenolics, metabolism, and gastrointestinal absorption of various metabolites and their health effects. This comprehensive volume: Discusses the bioavailability, bioaccessibility, pharmacokinetics studies, and microbial metabolism of different groups of phenolic compounds Examines the interaction between polyphenols and gut microbiota Describes analytical methods for identifying and quantifying polyphenols in foods and biological samples Reviews recent epidemiological and clinical intervention studies showing protective effects of polyphenols Dietary Polyphenols: Metabolism and Health Effects is an important resource for scientists working in the area of dietary polyphenols and health effects, microbiota, and their interaction with other nutritional compounds, and for health professionals, nutritionists, dieticians, and clinical researchers with interest in the role of polyphenols in the prevention and treatment of chronic diseases.
