In the current edition, Selenium: Its Molecular Biology and Role in Human Health expands extensively on the previous editions providing readers with the most significant advances in the rapidly developing selenium field. Evidence from epidemiology and veterinary science supports the essential role of selenium in (human) health, but its split personality in both preventing and supporting cancer and also in promoting insulin resistance has become more clearly defined. The pivotal role of glutathione peroxidase 4 in a new process of programmed cell death, ferroptosis, brings new impetus to the field. Recently defined mutations in selenoprotein and biosynthesis factor genes have been identified in patients, and the resulting disorders further emphasize the significance of selenoproteins in human health. The mechanism of selenoprotein biosynthesis, the functions of selenoproteins, and the roles of dietary selenium have been further elucidated, and new regulatory mechanisms involving selenoproteins discovered. The book, therefore, covers the breadth of current selenium research. With up-to-date chapters written by leaders in their fields, it serves as an invaluable resource for novices as well as specialists.
This book introduces readers to a wide range of applications for elements in Group 16 of the periodic table, such as, optical fibers for communication and sensing, X-ray imaging, electrochemical sensors, data storage devices, biomedical applications, photovoltaics and IR detectors, the rationale for these uses, the future scope of their applications, and expected improvements to existing technologies. Following an introductory section, the book is broadly divided into three parts—dealing with Sulfur, Selenium, and Tellurium. The sections cover the basic structure of the elements and their compounds in bulk and nanostructured forms; properties that make these useful for various applications, followed by applications and commercial products. As the global technology revolution necessitates the search for new materials and more efficient devices in the electronics and semiconductor industry, Applications of Chalcogenides: S, Se, and Te is an ideal book for a wide range of readers in industry, government and academic research facilities looking beyond silicon for materials used in the electronic and optoelectronic industry as well as biomedical applications.
Nucleic acids are the fundamental building blocks of DNA and RNA and are found in virtually every living cell. Molecular biology is a branch of science that studies the physicochemical properties of molecules in a cell, including nucleic acids, proteins, and enzymes. Increased understanding of nucleic acids and their role in molecular biology will further many of the biological sciences including genetics, biochemistry, and cell biology. Progress in Nucleic Acid Research and Molecular Biology is intended to bring to light the most recent advances in these overlapping disciplines with a timely compilation of reviews comprising each volume.
Research over the years has demonstrated that free radicals mediated oxidative stress lies at the helm of almost all patho-physiological phenomena. These findings emphasize on the need to understand the underlying molecular mechanism(s) and their critical role in the pathogenesis. This book aims to focus on these areas to provide readers a comprehensive outlook about the major redox sensitive pathways and networks involved in various disease conditions. In the first chapter of the book, basic information about the oxidative stress, its generation, its biomarkers and its role in body are discussed. In the next three chapters, the role of oxidative stress in various pathologies ranging from neurological disorders, to cardiovascular diseases, cancers, metabolic diseases and ageing have been described. Chapter 5 cumulatively describes the most important molecular signaling pathways that are affected by reactive oxygen species (ROS). These are the mechanisms which are common denominators in various pathological states. In the next part of the book, various antioxidant strategies to target and mitigate ROS have been discussed with details on the mechanisms. Selenium, being the research focus and interest of the authors for years, the role of selenium as an antioxidant as part of selenoproteins has been included in the book. Finally, the book culminates with authors’ perspective on the future of the redox biology field. Throughout the book, efforts have been made to use simplified language and suitable figures for ease to understand the contents. Although the authors have tried to touch on all the different aspects of oxidative stress in detail, the fact that it is a continuously growing field with updates coming every day, there might be some areas which might not be described in depth. This book is designed for students, young scientists to get acquainted with the redox biology. Overall, this book is a reference to understand the redox regulation of cellular signaling pathways involved in pathogenesis.

Selenium plays a fascinating and still poorly understood role in the function of living cells and therefore in human health. Starting with investigations over 60 years ago into its role as a toxic agent in livestock disease, selenium studies have progressed rapidly with the application of tools from immunology and molecular biology. Selenium is now known to be important in human and animal nutrition, has been discovered as a structural component of so-called selenoproteins, and may play a number of physiological roles, ranging from cancer protection to hormone metabolism. Selenium in Biology and Human Health presents research syntheses on a range of topics involving selenium, written by specialists from around the world. It will be of interest to cell biologists and physiologists, nutritional scientists, and animal health researchers.

The Role of Selenium in Nutrition reviews the most pertinent scientific literature dealing with the basic aspects of the present understanding of the roles of selenium (Se) in nutrition and health. The book begins with a general discussion of Se, covering its various forms, chemistry and physical properties, and techniques for Se analysis. This is followed by separate chapters on the environmental aspects of Se, including its presence in mineral deposits, soils, water, air, and uptake by plants; Se contents of human foods and animal feedstuffs; biological utilization of dietary Se; and absorption, excretion, metabolism, and tissue concentrations of Se. Subsequent chapters deal with the biochemical functions of Se; Se-related diseases of animals and livestock; the role of Se in human health and in support of normal immune function and disease resistance; and the relationship of Se and cancer. The final chapter reviews the evidence concerning the toxicity of Se compounds and sets this in perspective with current knowledge of the roles of Se in nutrition and health, and of the normal exposures of animals and humans to Se compounds.

Patients with the diagnosis "cancer" are increasingly asking for complementary procedures in the treatment of their disease. About 80% of all cancer patients are using complementary measures, frequently without the knowledge of the attending oncologist. Physicians and therapists therefore urgently need information on methods in complementary oncology that have been evaluated for efficacy. This book presents, for the first time, the integration of established complementary medical procedures into oncological treatment plans. Practicing oncologists will appreciate the book's accessible layout and well-organized tables when using the book as a reference work for quick answers and as a resource when counseling cancer patients. For oncologists involved in scientific research this book provides a comprehensive, critical insight into relevant research findings. Based on the criteria of evidence-based medicine (EBM), the book presents reliable information on complementary oncological procedures and straightforward treatment plans - which are always combined with the approved standard therapies and can be directly put into practice. An overview of reliable information on complementary methods in oncology Straightforward treatment plans for the practice A competent guide when counseling cancer patients.
