Book Description
Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.

Book Description
This book provides a comprehensive review on the status of iron nutrition in plants. It contains updated reviews of most relevant issues involving Fe in plants and combines research on molecular biology with physiological studies of plant-iron nutrition. It also covers molecular aspects of iron uptake and storage in Arabidopsis and transmembrane movement and translocation of iron in plants. This book should serve to stimulate continued exploration in the field.

Book Description
Metal ions play key roles in biology. Many are essential for catalysis, for electron transfer and for the fixation, sensing, and metabolism of gases. Others compete with those essential metal ions or have toxic or pharmacological effects. This book is structured around the periodic table and focuses on the control of metal ions in cells. It addresses the molecular aspects of binding, transport and storage that ensure balanced levels of the essential elements. Organisms have also developed mechanisms to deal with the non-essential metal ions. However, through new uses and manufacturing processes, organisms are increasingly exposed to changing levels of both essential and non-essential ions in new chemical forms. They may not have developed defenses against some of these forms (such as nanoparticles). Many diseases such as cancer, diabetes and neurodegeneration are associated with metal ion imbalance. There may be a deficiency of the essential metals, overload of either essential or non-essential metals or perturbation of the overall natural balance. This book is the first to comprehensively survey the molecular nature of the overall natural balance of metal ions in nutrition, toxicology and pharmacology. It is written as an introduction to research for students and researchers in academia and industry and begins with a chapter by Professor R J P Williams FRS.

Book Description
Iron is of fundamental importance to the growth, development and well-being of almost all living organisms. Multiple biological systems have evolved for the uptake, utilisation, storage, and homeostasis of iron in microbes, plants and mammals. Both iron deficiency and iron overload are found extensively in humans; the intimate links between iron and oxidative stress are associated with a wide range of pathologies. Iron has a well established role in infections by a range of microorganisms and parasites. Other metals such as copper and zinc are also closely linked with iron metabolism. Iron overloads and deficiencies are important factors in the health of humans and are therefore a key target in drug development. Iron Metabolism: From Molecular Mechanisms to Clinical Consequences, 3rd Edition presents a comprehensive overview of this important field.Topics covered include: Solution chemistry of iron in biological media The importance of iron for biological systems Microbial iron transport and metabolism Iron uptake by plants and fungi Cellular iron uptake and export in mammals Intracellular iron storage and biomineralization Intracellular iron metabolism and cellular iron homeostasis Iron absorption in mammals, with particular reference to man, and regulation of systemic iron balance Pathophysiology of iron deficiency and iron overload in man Iron and oxidative stress Brain iron homeostasis and its perturbation in various neurodegenerative diseases Interactions between iron and other metals Written in a lively style by one of the leaders in the field and presented in full colour, this third, expanded edition of Iron Metabolism has been fully updated with the latest discoveries. Major additions include recent information on mitochondrial iron metabolism and the role of frataxin; transcriptional control of iron homeostasis; orally active iron chelators; the roles of hepcidin and erythropoietin; the increasing number of types of iron overload; and the importance of iron in Alzheimer’s disease. Iron Metabolism is essential reading for researchers and students in biochemistry, molecular biology, microbiology, cell biology, nutrition and the medical sciences. It will also find space on the bookshelves of bioinorganic chemists with an interest in iron metabolism, health professionals with an interest in diseases of iron metabolism, and pharmacologists in the pharmaceutical industry interested in developing novel iron-binding drugs.
