Polyphenols in Human Health and Disease documents antioxidant actions of polyphenols in protection of cells and cell organelles, critical for understanding their health-promoting actions to help the dietary supplement industry. The book begins by describing the fundamentals of absorption, metabolism and bioavailability of polyphenols, as well as the effect of microbes on polyphenol structure and function and toxicity. It then examines the role of polyphenols in the treatment of chronic disease, including vascular and cardiac health, obesity and diabetes therapy, cancer treatment and prevention, and more. - Explores neuronal protection by polyphenol metabolites and their application to medical care - Defines modulation of enzyme actions to help researchers see and study polyphenols' mechanisms of action, leading to clinical applications - Includes insights on polyphenols in brain and neurological functions to apply them to the wide range of aging diseases

Inorganic Species, Part 1 separately considers the various inorganic and organic components that occur in water. While this separation is traditional, it does provide some distinct organizational advantages. This is important because of the wide-ranging audience likely to be using these works. Both practicing professionals and students in environmentally related disciplines will find these volumes to be a useful reference source. This book comprises six chapters, and begins with a focus on the origin and nature of selected inorganic constituents in natural waters. Succeeding chapters go on to discuss redox potential, which discusses its measurement and importance in water systems; alkalinity and acidity; conductance, which is defined here as a collective measure of dissolved ions; the theory and measurement of turbidity and residue; and, finally, a summary of methods for water-quality analysis of specific species. This book will be of interest to practitioners in the fields of geology and environmental engineering.
