Amyotrophic lateral sclerosis (ALS), characterized by degeneration of spinal motor neurons, consists of sporadic and familial forms. One cause of familial ALS is missense mutations in the superoxide dismutase 1 (SOD1) gene. Iron accumulation occurs in the CNS of both forms of ALS; however, its contribution to the pathogenesis of ALS is not known. We examined the role of iron in a transgenic mou...

Although blood transfusions are important for patients with anemia, chronic transfusions inevitably lead to iron overload as humans cannot actively remove excess iron. The cumulative effects of iron overload lead to significant morbidity and mortality, if untreated. Although the current reference standard iron chelator deferoxamine has been used clinically for over four decades, its effectivene...

Introduction: Adherence to the treatment regimen is among the key principles in chronic diseases, like thalassemia. The difficult treatment of these patients and the significant biopsychosocial changes that occur during adolescence may lead to numerous psychosocial changes. Such issuesmay affect their adherence to the treatment regimen. Objective: The current study aimedto deter...

Background:  Deferasirox is an oral iron chelator widely used to treat iron overload in patients with transfusion-dependent β-thalassemia. This study investigated the prevalence of visual and auditory complications caused by deferasirox. Materials and Methods: This cross-sectional study included 156 patients aged less than 18 years with transfusion-dependent β-thalassemia and deferasirox iron...

Iron availability affects swarming and biofilm formation in various bacterial species. However, how bacteria sense iron and coordinate swarming and biofilm formation remains unclear. Using Serratia marcescens as a model organism, we identify here a stage-specific iron-regulatory machinery comprising a two-component system (TCS) and the TCS-regulated iron chelator 2-isocyano-6,7-dihydroxycoumari...

Background: Iron is an essential mineral for normal cellular physiology but its ‎overload can lead to cell injury. For many years, deferoxamine injection has been used ‎as an iron chelator for treatment of iron overload. The aim of this study is to compare ‎oral deferoxamine, activated charcoal, and vitamin C, as an absorbent factor of Fe, in ‎changing the serum level of iron in iron overload r...
