Download or read book Physiology and Pathophysiology of Iron in Humans written by Rosalia Kripke and published by American Medical Publishers. This book was released on 2023-09-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For human beings, iron is an important trace element. It is required for various bodily processes such as cell growth and division, oxygen transport, various catalytic reactions, and oxidative metabolism. Human body requires only a small amount of iron on a daily basis. It must be consumed in a strictly monitored manner because there is no mechanism for excreting excess iron out of the body. Erythropoiesis, i.e., the production of new blood cells, takes place in the bone marrow, which is the major consumer of iron. The reticuloendothelial system helps in recycling iron by erythrocyte phagocytosis. Various proteins are involved in iron metabolism. For instance, hepcidin is a liver-derived peptide hormone that works as a major regulator of iron metabolism. This book explores all the important aspects of the physiology and pathophysiology of iron in the present day scenario. It is a valuable compilation of topics, ranging from the basic to the most complex advancements. Those in search of information to further their knowledge will be greatly assisted by this book.
Download or read book Iron Metabolism written by Robert Crichton and published by John Wiley & Sons. This book was released on 2016-03-30 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iron is indispensable for the growth, development and well-being of almost all living organisms. Biological systems from bacteria, fungi and plants to humans have evolved systems for the uptake, utilisation, storage and homeostasis of iron. Its importance for microbial growth makes its uptake systems a natural target for pathogenic microorganisms and parasites. Uniquely, humans suffer from both iron deficiency and iron overload, while the capacity of iron to generate highly reactive free radicals, causing oxidative stress, is associated with a wide range of human pathologies, including many neurodegenerative diseases. Whereas some essential metal ions like copper and zinc are closely linked with iron metabolism, toxic metals like aluminium and cadmium can interfere with iron metabolism. Finally, iron metabolism and homeostasis are key targets for the development of new drugs for human health. The 4th edition of Iron Metabolism is written in a lively style by one of the leaders in the field, presented in colour and covers the latest discoveries in this exciting area. It will be essential reading for researchers and students in biochemistry, molecular biology, microbiology, cell biology, nutrition and medical sciences. Other interested groups include biological inorganic chemists with an interest in iron metabolism, health professionals with an interest in diseases of iron metabolism, or of diseases in which iron uptake systems are involved (eg. microbial and fungal infections, cancer, neurodegenerative disorders), and researchers in the pharmaceutical industry interested in developing novel drugs targeting iron metabolism/homeostasis.

This book was released on 2002-07-19 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

Download or read book Iron Chelation Therapy written by Chaim Hershko and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last few years, iron research has yielded exciting new insights into the under standing of normal iron homeostasis. However, normal iron physiology offers little protec tion from the toxic effects of pathological iron accumulation, because nature did not equip us with effective mechanisms of iron excretion. Excess iron may be effectively removed by phlebotomy in hereditary hemochromatosis, but this method cannot be applied to chronic anemias associated with iron overload. In these diseases, iron chelating therapy is the only method available for preventing early death caused mainly by myocardial and hepatic iron toxicity. Iron chelating therapy has changed the quality of life and life expectancy of thalassemic patients. However, the high cost and rigorous requirements of deferoxamine therapy, and the significant toxicity of deferiprone underline the need for the continued development of new and improved orally effective iron chelators. Such development, and the evolution of improved strategies of iron chelating therapy require better understanding of the pathophysiology of iron toxicity and the mechanism of action of iron chelating drugs. The timeliness of the present volume is underlined by several significant develop ments in recent years. New insights have been gained into the molecular basis of aberrant iron handling in hereditary disorders and the pathophysiology of iron overload (Chapters 1-5).
Download or read book The Importance Of Iron In Pathophysiologic Conditions written by Raffaella Gozzelino and published by Frontiers Media SA. This book was released on 2015-06-09 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The iron element (Fe) is strictly required for the survival of most forms of life, including bacteria, plants and humans. Fine-tuned regulatory mechanisms for Fe absorption, mobilization and recycling operate to maintain Fe homeostasis, the disruption of which leads to Fe overload or Fe depletion. Whereas the deleterious effect of Fe deficiency relies on reduced oxygen transport and diminished activity of Fe-dependent enzymes, the cytotoxicity induced by Fe overload is due to the ability of this metal to act as a pro-oxidant and catalyze the formation of highly reactive hydroxyl radicals via the Fenton chemistry. This results in unfettered oxidative stress generation that, by inducing protein, lipid and DNA oxidation, leads to Fe-mediated programmed cell death and organ dysfunction. Major and systemic Fe overloads occurring in hemochromatosis and Fe-loading anemias have been extensively studied. However, localized tissue Fe overload was recently associated to a variety of pathologies, such as infection, inflammation, cancer, cardiovascular and neurodegenerative disorders. In keeping with the existence of cross-regulatory interactions between Fe homeostasis and the pathophysiology of these diseases, further investigations on the mechanisms that provide cellular and systemic adaptation to tissue Fe overload are instrumental for future therapeutic approaches. Thus, we encourage our colleagues to submit original research papers, reviews, perspectives, methods and technology reports to contribute their findings to a current state of the art on a comprehensive overview of the importance of iron metabolism in pathophysiologic conditions.

Download or read book The Physiology and Pathology of Iron in Pregnancy written by Allison Lynn Fisher and published by . This book was released on 2020 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iron is an essential nutrient required for vital metabolic and cellular processes. Despite its importance, it is poorly understood how maternal and fetal iron homeostasis is regulated during pregnancy, including the contribution of the maternal, placental, and fetal signals during healthy pregnancy or in conditions of iron deficiency and excess. Maternal iron insufficiency causes anemia, which is a global health problem linked to adverse outcomes. Iron availability in maternal circulation is ensured by the physiological suppression of the hormone hepcidin. We showed that suppression of maternal hepcidin during pregnancy is essential for embryo health, as high maternal hepcidin activity induced by administering a hepcidin mimetic to pregnant mice caused severe iron restriction and anemia in dams and embryos, low birthweight, and embryo mortality. Using mouse models, we showed that during maternal iron deficiency, maternal hepcidin is further suppressed, but this is not sufficient to maintain plasma iron levels and embryo iron endowment. With severe iron deficiency, the placenta altered iron transporters to preserve its own iron and metabolic function at the expense of the fetus, ultimately protecting the fetus from the consequences of placental dysfunction. We further showed that embryo hepcidin does not regulate placental iron transfer under physiological conditions. However, in mouse, rhesus macaques and human pregnancies complicated by inflammation, we found that fetal hepcidin was increased and associated with fetal hypoferremia. The fetus's ability to respond to inflammatory signals represents a conserved mechanism thought to be important in fetal host defense. We discovered in mouse models an adverse interaction between maternal iron excess and inflammation that led to embryotoxicity which was not observed with either condition alone. Embryotoxicity was observed not only in a mouse model of systemic acute inflammation induced by bacterial lipopolysaccharide, but also with chronic inflammation caused by diet-induced obesity. We found that maternal iron excess increased oxidative stress in the placenta and embryo endothelium, which sensitized the placental and embryo endothelium to inflammation-induced lethal apoptotic damage. The interaction between iron excess and inflammation is dependent on TNF -signaling and can be reversed by maternal anti-TNF and antioxidant therapy. These findings raise important questions about the safety of indiscriminate iron supplementation in pregnant women with underlying inflammation. We analyzed the interaction between iron, inflammation, and the endothelium in cultured endothelial cells. Iron loading induced cholesterol biosynthesis, promoted novel TNFR1 proteolytic processing, and sensitized cells to TNF -mediated apoptosis. We determined that during iron excess, the contribution of altered cholesterol homeostasis is the driving pathogenic mediator of apoptosis. Altered cholesterol metabolism by iron excess in endothelial cells may contribute to iron-mediated toxicity in human iron overload disorders. We further described that iron deficiency in pregnant mice also adversely interacts with inflammation caused by acute and chronic inflammation, triggered respectively by lipopolysaccharide and diet-induced obesity. Only the combination of maternal iron deficiency and inflammation caused embryo malformations and demise. Iron deficiency potentiated placental inflammation in complicated pregnancies, and in normal pregnancies iron deficiency induced TNF -receptor 1 expression in mouse and human placentas, representing possible mechanisms for how iron deficiency worsens outcomes in inflamed pregnancies. We defined the pathophysiology of iron regulation in pregnancy and articulated several novel concepts: placental adaptation to limited iron availability, the roles of maternal and fetal hepcidin, and adverse synergy between iron and inflammation. The discovery of the interaction between iron and inflammation highlights the utility of iron status as a modifying factor to ameliorate severity of injury in inflamed pregnancy and in a variety of inflammatory conditions outside of pregnancy. These concepts have translational impact and may eventually inform the clinical management of pregnant women worldwide.
Download or read book Military Strategies for Sustainment of Nutrition and Immune Function in the Field written by Institute of Medicine and published by National Academies Press. This book was released on 1999-05-13 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
