BACKGROUND The assessment of cardiac iron overload in thalassemia major has been considered as an important predictive factor of heart injury. The magnetic resonance imaging (MRI)-derived relaxation time parameter (T2*) varies inversely with iron level, and elevated myocardial iron levels by T2* are associated with depressed left ventricular (LV) ejection fraction (EF). We compared echocardiogr...

Background. Chronic Helicobacter pylori infection and iron-deficiency anemia (IDA) are common in adults. Although the most common causes of IDA usually arise from the gastrointestinal tract, the association between chronic Helicobacter pylori infection and anemia remains unclear. Aim. To evaluate the association of chronic Helicobacter pylori infection and IDA. Materials and Methods. We enrolle...

BACKGROUND Coronary Artery Disease (CAD) is the most important cause of mortality in the world. About half of cardiovascular risk factors have not been completely understood. Oxidation of LDL by oxidants such as iron plays a central role in atherogenesis. As a result, evaluation of the iron stores is important in the risk evaluation of the atherosclerotic disease. MATERIALS AND METHODS This c...

introduction: aim was to study the influence of serum testosterone and urinary citrate on the formation of urinary stones in men and women, and to apply the findings for preventing urolithiasis. methods: we studied 200 patients (100 were men and 100 women) who had referred to the urology clinic at imam khomeini hospital and seda sima eswl center. in both groups, 50 were stone formers and 50 wer...

background & objective: lichen planus is a mucocutaneous disease which is relatively common and in 30-70% of patients, mucosal lesions can be seen and known as a precancerous lesion but its etiology is not completely understood. desmogleins i and iii are the main desmosomal transmembrane proteins. these proteins have been identified as the autoantigen of the autoimmune disease. the aim of t...

background : the measuring serum ferritin level as a sensitive inflammatory biomarker might effectively predict preterm delivery, but the power and the best cut-off point of this biomarker for predicting preterm labor in iranian population has not been substantially identified. our purpose was to determine what concentrations of serum ferritin could identify patients at risk for preterm deliver...

The combined addition of reduced form of glutathione (GSH) and iron chelators for decrease of the intracellular level of reactive oxygen species (ROSs) and death of Chinese hamster ovary (CHO) cells was investigated. The addition of GSH to the serum-free cultures of CHO cells markedly lowered the intracellular ROS level, which effect was comparable to that of the addition of serum (0.4, 10%) an...

Excess iron causes cell injury by reacting with superoxide anions (O2*) and hydrogen peroxide (H2O2) and producing hydroxyl radical (OH*) and reactive oxygen species (ROS). In the present study, albino rats were fed with biscuits enriched with ferrous sulphate (0.3% w/w) for 10 weeks to have overload iron conditions and observed a significant decrease in serum chromium, brain serotonin and dopa...

The effects of administration of aqueous extract of Alchornea laxiflora leaf at doses of 100, 200 and 300 mg/kg body weight on some antioxidant enzymes and lipid peroxidation in iron deficient albino rats were investigated. Thirty six albino rats (51.17±1.02g) were used for the study. Eight rats were fed on iron-sufficient diet while the remaining twenty eight were made iron-deficient by mainta...
