Metallothioneins (MTs) represent a large family of proteins characterized by high heavy metal content (mainly CuII and ZnII) and by an unusual cysteine abundance. They have a powerful protective function in all animal tissues, due most likely to their properties as free radical scavengers protecting against oxidative damage. Moreover, the presence and overexpression of MTs in various pathological conditions, such as metal dyshomeostasis, cell proliferation, neurological disorders, and chemotherapy and radiotherapy resistance, could be used as an important prognostic marker, as a histopathological diagnostic tool, and to follow specific pharmacological treatments.This important book explores the role of MTs in the field of neurological disorders (brain inflammation, Alzheimer''s and prion diseases, autism, ALS, etc.), cardiology (cardiomyopathy, atherosclerosis), and oncology (melanoma, prostate and breast cancer), through authoritative contributions and a description of basic biochemical information and paradigmatic pathological events.

Numerous studies have established a clear connection between neuronal oxidative stress and several neurodegenerative diseases, with consequential damages to lipids, proteins, nucleic acids, etc. In addition, several modifications indicative of oxidative stress have been described in association with neurons, neurofibrillary tangles and senile plaques in Alzheimer''s disease, including advanced glycation end products and free carbonyl oxidation.Oxidative damage and antioxidant responses are now well characterized, but sources of damaging free radicals are yet to be fully understood. Evidences of alteration in metal ions metabolism have been reported in various diseases like Alzheimer''s, Wilson, Menkes, Prion, Pick, Huntington disease, epilepsy and other pathological events. Thus, metal ions play a pivotal role in neurodegenerative phenomena.Chelation therapy is still in the early days of its development, but research in this area could lead to new products that could revolutionize treatment. Two international conferences on “Metals and the Brain: From Neurochemistry to Neurodegeneration” (Padova, Italy, 2000 and Fez, Morocco, 2002) were recently held to discuss the role of metal ions in neurophysiopathology. A third will be held in 2005 in Johannesburg, South Africa.This book follows the same train of thought as those conferences, in order to highlight the unquestionable importance of metal ions in the research on the neurophysiopathology of neurodegenerative diseases. The excellent reputation of the scientists who have contributed to this project ensures the quality of the chapters presented here, and hopefully this will help spur new research initiatives in the field, which is still in its infancy.

Aluminium is the most abundant metal ion in the biosphere and we are continuously exposed to it in our everyday life through food, beverages, pharmaceutical products, etc. This book is a current and comprehensive review of the biochemistry, metabolism and toxicity of aluminium undertaken by an international group of authors, many of whom are outstanding authorities in their respective fields. In contrast with previous books on this topic, much of the subject matter is unique, in that it is primarily directed at aluminium nutrition and toxicity in infants and children. This book covers many aspects of aluminium toxicity in infants including for instance the embryo-fetal as well as the neurodevelopmental effects of this element, contamination of pharmaceutical products, and individual sensitivity through vaccines using aluminium as an adjuvant.This book will be especially useful to paediatricians, paediatric nephrologists & neurologists, nutritionists, toxicologists, biochemical toxicologists and postgraduate students.
