Grate bar is an industrial part which is used in the indurating furnace of an iron ore pelletizing plant. Steel part ofthe grate bars are expected to have high resistance to atmospheric oxidation because of its contact with hot gases(up to 920 °C) during the normal operation of the process. In this study, different samples from several sections ofused grate bars with apparent ...

background: oxidative modification of low-density lipoprotein (ldl) appears to be an early step in the pathogenesis of atherosclerosis. meanwhile, myeloperoxidase (mpo)-catalyzed reaction is one of the potent pathway for ldl oxidation in vivo. the aim of this study was to evaluate in vitro antioxidant effects of vitamins c and e on ldl oxidation mediated by mpo. methods: mpo was isolated from f...

In order to enhance the performance of interconnects which are used in solid oxide fuel cells (SOFCs), a protective/conductive coating can be applied. In this research AISI 430 ferritic stainless steel was coated in a Mn-base pack mixture by pack cementation method. In order to evaluate the oxidation behavior, isothermal oxidation was accomplished for 200 h at 800 ºC. Electrical behavior was al...

quinol oxidation inhibitors (qois) are one of the most important classes of fungicides used in agriculture. they block electron transfer between cytochrome b and cytochrome c1, thereby impeding the production of atp via oxidative phosphorylation. qoi fungicides are generally at high risk of provoking resistance in fungal phytopathogens. resistance has been reported in more than thirty species, ...

BACKGROUND It has been proposed that muscle insulin resistance in type 2 diabetes is due to a selective decrease in the components of the mitochondrial electron transport chain and results from accumulation of toxic products of incomplete fat oxidation. The purpose of the present study was to test this hypothesis. METHODOLOGY/PRINCIPAL FINDINGS Rats were made severely iron deficient, by means...

oxidation of low-density lipoprotein (ldl) has been strongly suggested as a key factor in the pathogenesis of atherosclerosis. thus, the inclusion of some anti-oxidant compounds in daily dietary food stuff may inhibit the production of oxidized ldl and may decrease both the development and the progression of atherosclerosis. the present work investigated the inhibitory effects of extract of all...

Background: Oxidative modification of low-density lipoprotein (LDL) appears to be an early step in the pathogenesis of atherosclerosis. Meanwhile, myeloperoxidase (MPO)-catalyzed reaction is one of the potent pathway for LDL oxidation in vivo. The aim of this study was to evaluate in vitro antioxidant effects of vitamins C and E on LDL oxidation mediated by MPO. Methods: MPO was isolated from f...
