Oxidation of Low-Density Lipoprotein by Iron at Lysosomal pH: Implications for Atherosclerosis
Low-density lipoprotein (LDL) has recently been shown to be oxidized by iron within the lysosomes of macrophages, and this is a novel potential mechanism for LDL oxidation in atherosclerosis. Our aim was to characterize the chemical and physical changes induced in LDL by iron at lysosomal pH and to investigate the effects of iron chelators and α-tocopherol on this process. LDL was oxidized by i...
متن کاملComparative Effects of Copper, Iron, Vanadium and Titanium on Low Density Lipoprotein Oxidation in vitro
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 (...
متن کاملحذف پایرن از خاک های آلوده به روش اکسیداسیون فنتون اصلاح شده با استفاده از نانو ذرات آهن
Background and Aim: Problems related to conventional Fenton oxidation, including neccesity of having a low pH and production of considerable amounts of sludge, have prompted researchers to consider chelating agents to improve the pH operating range and iron nano-oxide particles to reduce excess sludge. The main objective of this study was to remove pyrene from contaminated soils by a modified F...
متن کاملEffect of pH and Temperature on Iron Oxidation by Mesophilic Mixed Iron Oxidizing Microflora
The aim of the work described in this paper was to establish the effect of physical parameters such as pH and temperature on the microbial growth and iron oxidation rate of an isolated iron oxidizing bacterial strain from mine effluent. The bacterial lag phase was reduced to zero by repeated subculturing in fresh nutrient media. The rate of iron oxidation was considered as the growth rate of th...
متن کاملMicrobiological oxidation of ferrous iron at low temperatures.
Acidophilic iron-oxidizing bacteria were enriched from mine water samples with ferrous sulfate as the substrate at incubation temperatures in the range of 4 to 46 degrees C. After several subcultures at each test temperature except 46 degrees C, which was prohibitive to growth, the rates of iron oxidation were determined in batch cultures. The results yielded linear rates in a semilogarithmic s...
