Manganese mineralization is diverse in occurence, origin, mineralogy and geochemistry. This volume includes a review of the range of terrestrial Mn deposits and their relative abundance through geological time. Experimental and modelling approaches to Mn geochemistry and mineralogy can further aid our understanding of the formational and depositational processes involved and thereby our interpretation of deposit metallogenesis.

Explains the characteristics of manganese, where it is found, how it is used by humans, and its relationship to other elements found in the periodic table.

Manganese in Health and Disease discusses recent advances of the role of manganese on different human pathologies. The book presents research discussing the possible role of manganese in the development of some degenerative diseases such as diabetes, osteoporosis, and atherosclerosis. The role of manganese in individuals with epilepsy and congenital malformations is also discussed. This comprehensive book will interest basic researchers and clinicians including research scientists, physicians, nutritionists, dietitians, nurses, and educators.

This volume provides an update on the chemistry of manganese, technetium and rhenium covered in Volume 4 of COMC. The literature surveyed is from 1982 to 1993. The explosive growth in organorhenium chemistry, the use of manganese hydrocarbon complexes in organic synthesis, and the development of the chemistry of high oxidation manganese and rhenium compounds are highlighted. The growth of organotechnetium chemistry which was virtually unknown at the time of COMC is covered in depth.

Volume 19, entitled Essential Metals in Medicine: Therapeutic Use and Toxicity of Metal Ions in the Clinic of the series Metal Ions in Life Sciences centers on the role of metal ions in clinical medicine. Metal ions are tightly regulated in human health: while essential to life, they can be toxic as well. Following an introductory chapter briefly discussing several important metal-related drugs and diseases and a chapter about drug development, the focus is fi rst on iron: its essentiality for pathogens and humans as well as its toxicity. Chelation therapy is addressed in the context of thalassemia, its relationship to neurodegenerative diseases and also the risks connected with iron administration are pointed out. A subject of intense debate is the essentiality of chromium and vanadium. For example, chromium(III) compounds are taken as a nutritional supplement by athletes and bodybuilders; in contrast, chromate, Cr(VI), is toxic and a carcinogen for humans. The benefi cial and toxic effects of manganese, cobalt, and copper on humans are discussed. The need for antiparasitic agents is emphasized as well as the clinical aspects of metal-containing antidotes for cyanide poisoning. In addition to the essential and possibly essential ones, also other metal ions play important roles in human health, causing harm (like the metalloid arsenic, lead or cadmium) or being used in diagnosis or treatment of human diseases, like gadolinium, gallium, lithium, gold, silver or platinum. The impact of this vibrant research area on metals in the clinic is provided in 14 stimulating chapters, written by internationally recognized experts from the Americas, Europe and China, and is manifested by approximately 2000 references, and about 90 illustrations and tables. Essential Metals in Medicine: Therapeutic Use and Toxicity of Metal Ions in the Clinic is an essential resource for scientists working in the wide range from pharmacology, enzymology, material sciences, analytical, organic, and inorganic biochemistry all the way through to medicine ... not forgetting that it also provides excellent information for teaching.
