The case of a 59 year old white man who had chronic malabsorption and selective IgA deficiency with severe iron deficiency is reported. In addition, he was deficient in vitamin E and selenium, important antioxidants which protect against lipid peroxidation. He was intolerant of oral iron and when treated with iron-dextran developed symptoms suggestive of polymyositis with evidence of rhabdomyol...

Rheumatoid arthritis is a chronic inflammatory polyarthritis characterised by an inflammatory cell infiltration of the synovial membrane. I t has been suggested that in these patients an aggressive oxidant such as the OH’ radical may be responsible for membrane damage and other harmful effects within the synovial membrane [l]. Iron, in a form able to catalyse OH’ formation may be released from ...

Ni-Hard4 white cast iron is excellent wear resistant material and has been widely used in wearaffected equipment operated under extreme conditions, such as in mineral processing, cement, copper and iron manufacturing. In this study the effect of titanium addition (1.2, 0.7 and 0.2 wt.%) to the Ni-hard 4 cast iron with the nominal composition of Si= 1.5%, Mn=0.5%, C=3%, P=0.05%, S= 0.05%, Mo= 0....

Pregnancy, mostly because of the mitochondria-rich placenta, is a condition that favors oxidative stress. Transitional metals, especially iron, which is particularly abundant in the placenta, are important in the production of free radicals. Protective mechanisms against free radical generation and damage increase throughout pregnancy and protect the fetus, which, however, is subjected to a deg...

background: the most common metal used in the body is iron and since it may produce ros, it could potentially be a dangerous substance. objectives: regarding the side effects of nanomaterials such as nano iron particles and possibility of environmental contamination including air pollution with nanoscale iron particle, this study was designed to compare the effects of conventional iron oxide wi...
