Metal Ion in Stroke

by John H. Zhang Yang V. Li

Stroke is a major cause of death and disability in the U.S. and worldwide.

Metal Ions in Biochemistry: 2nd Edition

by Pabitra Krishna Bhattacharya Prakash B. Samnani

The second edition of Metal Ions in Biochemistry deals with the multidisciplinary subject of bio-inorganic chemistry, encompassing the disciplines of inorganic chemistry, biochemistry and medicine. The book deals with the role of metal ions in biochemistry, emphasising that biochemistry is mainly the chemistry of metal-biochemical complexes. Hence, the book starts with the structures of biochemicals and the identification of their metal binding sites. Thermodynamic and kinetic properties of the complexes are explained from the point of view of the nature of metal-ligand bonds. Various catalytic and structural roles of metal ions in biochemicals are discussed in detail. Features The role of Na+ and K+ in brain chemistry. The role of zinc insulin in glucose metabolism and its enhancement by vanadium and chromium compounds. Discussion of the role of zinc signals, zinc fingers and cascade effect in biochemistry. Haemoglobin synthesis and the role of vitamin B12 in it. The role of lanthanides in biochemical systems. A detailed discussion of the role of non-metals in biochemistry, a topic missing in most of the books on bio-inorganic chemistry. The study of bio-inorganic chemistry makes biochemists rethink the mechanistic pathways of biochemical reactions mediated by metal ions. There is a realisation of the role of metal complexes and inorganic ions as therapeutics such as iron in leukaemia, thalassemia and sickle cell anaemia, iodine in hypothyroidism and zinc, vanadium and chromium in glucose metabolism. The most recent realisation is of the use of zinc in the prevention and treatment of COVID-19.

Metal Ions in Neurological Systems

by Henryk Kozlowski Wolfgang Linert

Metal ions in the brain are a necessity as well as a poison. The presence of metal ions in the active sites of biological catalysts or metalloproteins and in the biological functioning of nucleic acids is very well documented and they are required for brain activity. On the other hand, metals are very effective in generating oxidative stress. This effect does not only play a role in immunology but also is the root of practically all neurodegenerative disorders by inducing disease via the death of neurons. Managing metal ions in the brain could therefore be an important strategy in the search for therapeutic agents used in the treatment of neurodegenerative diseases. This new title gives an overview to key topics in the area of metal ions in the brain. It focuses on the role of metal ions in neurological systems by describing their advantageous functions as well as their poisonous features. It is therefore of interest for scientists in biochemistry and biophysics, physiology, toxicology as well as for physicians focused on this topic.

Metal Toxicology Handbook

by Debasis Bagchi and Manashi Bagchi

Heavy metals and metalloids, singly or in combination, induce toxic manifestations either through acute or chronic pathology. In particular, long-term chronic exposure to diverse heavy metals and metalloids to humans and animals can lead to numerous physical, muscular, neurological, nephrological, and diverse degenerative diseases and dysfunctions, including multiple sclerosis, muscular dystrophy, Parkinson’s and Alzheimer’s diseases, cardiovascular disorders, and several others. Recognized heavy metals such as lead, mercury, arsenic, cadmium, thallium, and hexavalent chromium are known for enormous toxicity. The immediate vital signs of acute heavy metal exposure include nausea, vomiting, diarrhea, and acute abdominal pain. Mercury has been identified as the most toxic heavy metal, and mercury poisoning is known as acrodynia or pink disease. Similarly, lead, another toxic heavy metal, was at one time an integral part of painting. Metal Toxicology Handbook further explains and discusses the varying attributes of metals, discussing toxicity, safety, and proper human utilization of metals. Beginning with a broad overview of metals, metalloids, redox biology, and neurodegeneration and going further into the roles, benefits, and toxicity of metals with each section, the text contains 28 chapters from eminent researchers and scientists in their respective fields and is a must-have for anyone researching the potential toxicity in metals. Key Features Discusses the pathology of metal toxicity Highlights the benefits of metals Explains the mechanism and salient features of restoring metabolic homeostasis Highlights dose-dependent beneficial and adverse effects of vanadium safety and toxicity The initial introductory section provides a broad overview of metals, metalloids, redox biology, and neurodegeneration. The second section discusses the pathology of metal toxicity in two chapters, while the third section highlights the mechanism and salient features of restoring metabolic homeostasis in two chapters. The fourth section demonstrates the aspect of radionuclides toxicity. In a change of pace, the fifth section discusses the benefits of metals in four chapters. The sixth section, titled "Toxic Manifestations by Diverse Heavy Metals and Metalloids," provides fourteen chapters that discuss the toxicological mechanism and manifestation of individual metals. The editors have crafted a commentary titled "A Treatise on Metal Toxicity" and summarized a vivid scenario of metal toxicity and its consequences.
