Iron-reducing bacteria can transfer electrons to ferric iron oxides which are barely soluble at neutral pH, and electron-shuttling compounds or chelators are discussed to be involved in this process. Experiments using semipermeable membranes for separation of ferric iron-reducing bacteria from ferric iron oxides do not provide conclusive results in this respect. Here, we used ferrihydrite embed...

β-thalassemia is one of the most common hereditary diseases in Egypt. The leading causes renal dysfunction thalassemic patients include chronic anemia, iron overload from repeated blood transfusions, and kidney-induced damage use chelators.

abstract background: iron overload is a clinical consequence of repeated blood transfusions and causes significant organ damage, morbidity, and mortality in the absence of proper treatment. the primary targets of iron chelators used for treating transfusional iron overload are the prevention of iron ingress into tissues and its intracellular scavenging. the present study was aimed at elucidatin...

this work reports a facile sonochemical route in the synthesis of nano particle of deferasirox for the first time. one application of nanotechnology is in improvement of available treatments for various diseases. deferasirox (icl670 or exjade) is a tridentate chelating agent for removing transfusion overload iron in thalassemia patients. in the present work, deferasirox was prepared in nano size...

This study details the prevention of gentamicin-induced hearing loss in guinea pig in vivo. The approach is based on our recent demonstrations of a redox-active gentamicin-iron complex in vitro and partial attenuation of gentamicin-induced hearing loss by the iron chelators deferoxamine and 2,3-dihydroxybenzoate. In our study, guinea pigs receiving injections of gentamicin (120 mg/kg body weigh...

In view of the profound functional and structural abnormalities shown in our previous studies in cultured, iron-loaded rat heart cells, we have examined the ability of the orally effective iron chelators dimethyl-3-hydroxypyrid-4-one (DMHP or L1) and diethyl-3-hydroxy-pyrid-4-one (DEHP or CP94) and of deferoxamine (DF) to reverse the damage caused by iron loading to heart cell organelles. At a ...
