oxidation of low density lipoprotein (ldl) has been strongly implicated in the phathogenesis of atherosclerosis. the use of oxidants in dietary food stuff may lead to the production of oxidized ldl and may increase both the development and the progression of atherosclerosis. the present work investigated the effects of some elements including: copper (cu), iron (fe), vanadium (v) and titanium (...

Mutations in the HFE gene may be associated with increased tissue iron stores reflected in an elevated serum ferritin. With homozygous mutation C282Y, the increase in serum ferritin may be associated with tissue damage in the liver, pancreas, and pituitary and with a reduced bone mineral density. With heterozygous mutation C282Y, the degree of iron retention is less but information relating to ...

Corrosion resistance of iron can be drastically improved by addition of passivating alloying elements. A supersaturated solid solution of Fe-25at%Sn was produced by mechanical alloying of commercially pure iron and tin powders for 24 hours using a planetary ball mill. Electrochemical measurements were performed on cold compacted unsintered specimens.. XRD investigation on produced alloy showed ...

Determination of stockpile weight and stockpile inventory are critical to any quarry or mining operation, whether it is required by accounting firms or used internally for the quarterly balance of production and sales. Generally, errors and problems originate from two factors. Volume of stockpile that is traditionally worked out from the mapping results has a low accuracy due to irregular shape...

The effects of powder particle size on the densification and microstructure of iron powder in the direct laser sintering process were investigated. Iron powders with particle sizes ranging from 10 to 200 m were used. It was found that the sintered density increases as the laser energy input is increased. There is, however, a saturation level at which higher density cannot be obtained even at ve...

Background & Aims: The present study deals with an investigation on the effect of iron deficiency anemia and iron supplementation on anemia markers and plasma lipid profiles in pregnant women. Methods: A total of 350 pregnant women were taken and divided into four groups on the basis of haemoglobin levels viz. control (100), mild (100), moderate (100) and severe (50) patients. All the groups we...

OBJECTIVE To review the epidemiological and experimental data concerning iron and the development of atherosclerosis and ischemic heart disease. DATA SOURCES The English-language literature was searched from 1981 through 1998 manually and using MEDLINE and Current Contents. Important references in the articles that were found were also included in this review. RESULTS There is growing epide...

OBJECTIVE The aim of this study was to evaluate the impact of iron overload on the profile of interleukin-10 levels, biochemical parameters and oxidative stress in sickle cell anemia patients. METHODS A cross-sectional study was performed of 30 patients with molecular diagnosis of sickle cell anemia. Patients were stratified into two groups, according to the presence of iron overload: Iron ov...
