Metal-induced toxicity and carcinogenicity, with an emphasis on the generation and role of reactive oxygen and nitrogen species, is reviewed. Metal-mediated formation of free radicals causes various modifications to DNA bases, enhanced lipid peroxidation, and altered calcium and sulfhydryl homeostasis. Lipid peroxides, formed by the attack of radicals on polyunsaturated fatty acid residues of phospholipids, can further react with redox metals finally producing mutagenic and carcinogenic…

A review of metal‐catalyzed molecular damage: protection by melatonin

Melatonin, an ubiquitous and pleiotropic molecule, exerts efficient protection against oxidative stress and ameliorates oxidative/nitrosative damage by a variety of mechanisms, which may contribute in reducing metal‐induced toxicity as postulate here.

Non-redox cycling mechanisms of oxidative stress induced by PM metals.

The Role of Oxidative Stress in Metals Toxicity; Mitochondrial Dysfunction as a Key Player

The oxidative injuries induced by metals can be restored by use of antioxidants such as chelators, vitamin E and C, herbal medicine, and through increasing the antioxidants level, to elucidate many aspect of mechanism toxicity of metals.

Redox active metal-induced oxidative stress in biological systems

The role of iron and copper in uncontrolled formation of ROS leading to various human diseases such as cancer, cardiovascular disease, and neurological disorders (Alzheimer's disease and Parkinson's disease) is discussed and a discussion is devoted to the various protective antioxidant networks against the deleterious action of free radicals.

Heavy metal induced oxidative stress & its possible reversal by chelation therapy.

A comprehensive account of recent developments in the research on heavy metal poisoning particularly the role of oxidative stress/free radicals in the toxic manifestation is attempted, an update about the recent strategies for the treatment with chelating agents and a possible beneficial role of antioxidants supplementation to achieve the optimum effects are attempted.

Comparative oxidative stress, metallothionein induction and organ toxicity following chronic exposure to arsenic, lead and mercury in rats.

Exposure to sodium arsenite and mercuric chloride lead to more pronounced oxidative stress and hepatotoxicity while lead acetate caused significant alterations in haem synthesis pathway compared to two other thiol binding metal/metalloid.

Biomedical Implications of Heavy Metals Induced Imbalances in Redox Systems

The present review illustrates an account of the current knowledge about the effects of heavy metals induced oxidative stress as well as the possible remedies of metal toxicity through natural/synthetic antioxidants, which may render their effects by reducing the concentration of toxic metal(s).

SCE increased at all the tested concentrations except the lowest dose, while that low dose induced a significant effect on the induction of chromosomal aberrations in the germ cells, indicating that rifampicin has a potential clastogenic effect.


Recently, many cellular oncogenes were identified in human cancerous cells by the DNA transfection method, some of which were found to contain sequences related with already known viral oncogenees.


MRI revealed lesions of the central portions of the corpus callosum as well as the deep white matter of the left frontal lobe, which is possible to consider this case as MarchiafavaBignami disease.

The Metabolic Basis Of Inherited Disease.

This volume, more than most, explains the contributions of the laboratory to clinical medicine, and shedding light on fundamental metabolic sequences and biologic mechanisms.

The blood's functions include oxygen transport from lungs to tissues in exchange for waste carbon dioxide, transport of hormones, nutrients and waste products between organs, clotting to seal off haemorrhage and the transport of white cells to combat infection.
