This study was conducted to investigate the effects of dietary ascorbic acid (AA) on transcriptional expression patterns of antioxidant proteins, heat shock proteins (HSP) and nuclear factor kappa B (NF-κB) in the hepatopancreas of Pacific abalone Haliotis discus hannai Ino (initial average length: 84.36 ± 0.24 mm) using real-time quantitative PCR assays. L-ascorbyl-2-molyphosphate (LAMP) was added to the basal diet to formulate four experimental diets containing 0.0, 70.3, 829.8 and 4967.5 mg AA equivalent kg(-1) diets, respectively...

Neuroferritinopathy is an autosomal dominant, adult-onset disorder characterized by the deposition of iron and ferritin in the brain and a decreased level of serum ferritin. The disease is caused by mutations of the gene encoding ferritin light chain polypeptide. Seven pathogenic mutations have so far been reported, and two of the mutations were found in Japanese families. The mutations are predicted to affect tertiary structure and stability of the ferritin light chain polypeptide and may cause inappropriate iron release from feritin polymers...

Renal anemia is complication of chronic kidney disease. It is caused by crythropoietin deficency and is associated with adverse outcomes in CKD patients. Renal anemia should be treated with erythropoesis-stimulating agents (ESAs), supplementary iron, adequate dialysis, and if necessary with red blood cells transfusions. The main problem of treatment is how to determine target hemoglobin value and keep it within the constant range. Current guidelines recommend target hemoglobin level 110 - 120 g/l, but optimal value need to be adjusted for every patient individualy keeping in mind primary kidney disease, age, gender and comorbidities...

OBJECTIVE: To study the effectiveness and safety of deferasirox (DFX) in the treatment of iron overload in children with β-thalassemia major. METHODS: Twenty-four β-thalassemia major children with iron overload who received regular blood transfusion were randomly enrolled. The serum feritin (SF) levels were measured in the patients after different doses of DFX treatment. The DFX treatment-related adverse events were observed. The values of cardiac MRI T2* and liver MRI T2* were compared between the patients receiving DFX treatment for 5 years and the patients treated with deferoxamine and deferiprone...

This study involved all children with celiac disease admitted and seen in the Paediatric Gastroenterology Clinic at King Khalid University Hospital (KKUH) over a 10-year period. In the first year, we identified 62 cases with celiac disease. Their mean age at presentation, introduction to cereals in the diet, and onset of symptoms were 6.5, 6 and 6 months, respectively, and most of the children belonged to the indigenous population. There were three Arabia families with more than one affected child and most families were of good social status...

INTRODUCTION: A few small-scale studies have shown that high levels of various parameters of inflammation were associated with a less efficient response to erythropoetin. The responsiveness to EPO in haemodialysis (HD) patients with relative risk of cardiovascular disease (CVD) remains undetermined. In a retrospective study of HD patients, we compared causes of CV morbidity and mortality in relation to various weekly EPO doses needed for stable hemoglobin (Hb) levels, according to the definition currently suggested by international guidelines...

OBJECTIVE: To study the effect of different therapeutical regimens of Ferro-Folgamma, in pregnant patients with iron deficiency anemia. MATERIALS AND METHODS: 22 pregnant patients between 20 and 35 week of gestation (mean 29 gestational week) with hemoglobin levels between 83.1-106 g/l were included. They were divided in two groups: group 1 included patients with hemoglobin levels up to 100g/l and group 2--with hemoglobin levels between 100 and 110. The dosage of the preparation in group 1 was 1 tablet Ferro-Folgamma tid for 40 days, and 1 tablet Ferro-Folgamma bid for the same period...

BACKGROUND: It has been established that many patients with chronic hepatitis C have elevated serum iron, feritin levels and iron deposites in the liver. Therefore, the liver damage due to hepatitis C virus may be aggravated with iron overload. In many studies higher levels of iron in the blood and the liver were connected with the decreased response to interferon-alfa therapy for chronic viral hepatitis C. Recent introduction of pegylated interferons plus ribavirin has improved the therapeutic response, so it is now possible to cure more than 50% of the patients...

I.v. ascorbic acid has been used in an effort to mobilize ferritin stores in hyporesponsive HD patients receiving Epoetin alfa. However, not all patients who respond to i.v. ascorbic acid therapy will have subsequent decline in feritin stores (Gastaldello et al., 1995; Tarng & Huang, 1998). Additionally, predicting those patients who will overcome their Epoetin alfa hyporesponsiveness remains unclear. Ascorbic acid's effect on hemosiderin deposits may be another possible mechanism to the increased Epoetin alfa response observed in some HD patients (Hemosiderin is a pathologic deposition of iron in tissues including the spleen, small intestine, and bone marrow)...

The authors examined the transendothelial passage of tracer macromolecules (feritin) in the endothelial cells of the lung stem of white rats (Wistar) by means of an electron microscope. They found that the feritin granules were detained by the pilous surface of the luminal cytolema at the initial phase of the process. This was enhanced also by luminal buds and invaginations respectively paraluminal canals, functioning as stagnating devices. The uptake and transcellular passage of the macromolecules was realized by micropinocytose vesicules, part of which were intracellularly and formed vacuole depots...

Human neutrophils stimulated with phorbol myristate acetate or formylmethionylleucylphenylalanine caused superoxide-dependent release of iron from feritin, measured as the formation of a ferrous-ferrozine complex. The stimulated cells also caused ferritin-dependent peroxidation of phospholipid liposomes. Peroxidation was inhibited by lactoferrin, but only at concentrations considerably in excess of what could be achieved by release of endogenous lactoferrin. Peroxidation was enhanced by catalase and methionine, especially when stimulants that release myeloperoxidase were used...

The control of hepatic iron uptake was studied in the perfused liver isolated from rats subjected to nutritional iron deficiency. The total hepatic iron uptake and incorporation into ferritin was found to be higher in iron deficiency and during the 48 h of oral refeeding with iron than in the normal state. Specific incorporation of iron into feritin from a perfusate of normal transferrin iron saturation was enhanced in nutritional iron deficiency as compared to controls after 5 h of perfusion but not after 1 h, suggesting that increased uptake of iron from the perfusate may play a role in stimulating hepatic ferritin synthesis and assembly...

Human plasma low density lipoprotein (LDL) that had been rendered polycationic by coupling with N, N-dimethyl-1, 3-propanediamine (DMPA) was shown by electron microscopy to bind in clusters to the surface of human fibroblasts. The clusters resembled those formed by polycationic ferritin (DMPA-feritin), a visual probe that binds to anionic site on the plasma membrane. Biochemical studies with (125)I-labeled DMPA-LDL showed that the membrane-bound lipoprotein was internalized and hydrolyzed in lysosomes. The turnover time for cell bound (125)I-DMPA-LDL, i...
