Iron is transported throughout the body as part of the transferrin protein and is stored as ferritin. The earliest stage of iron deficiency occurs when stores are depleted, characterized by a drop in serum ferritin levels and an increase in total iron binding capacity that refers to incomplete saturation of the transferrin molecule. Serum ferritin levels below 12 μg/l are associated with comple...

BACKGROUND Women who inherit heterozygosity for the C282Y mutation of the HFE gene may have increased serum iron indices and hemoglobin and are less likely to develop iron deficiency compared with women with the wild-type genotype. METHODS We performed a cross-sectional analysis of 497 women 20-44 years of age and 830 women >51 years of age drawn from the Busselton (Australia) population stud...

We thank Conway for his comment (1) on our article in Diabetes Care (2) on the risk of diabetes associated with elevated transferrin saturation levels in two follow-up studies (risk as hazard ratios and exposure preceding disease) and a case-control study (risk as odds ratio) with neither study being cross-sectional. We agree with Conway that the pathophysiology of diabetes is complex. We ackno...

BACKGROUND Iron deficiency (ID) is common in patients with cystic fibrosis (CF) and may be related to GI factors and chronic inflammation. Pseudomonas aeruginosa (PA) infection is predominantly responsible for chronic lung suppuration in patients with CF, but its survival is critically dependent on the availability of extracellular iron, which it obtains via highly efficient mechanisms. OBJEC...

Hepcidin, produced in the liver, is a key regulator of systemic iron metabolism. This study aimed to estimate the significance of hepcidin for diagnosis of iron deficiency anemia (IDA) among children and to determine whether routine hematological parameters and iron profile correlate with hepcidin levels in children in Saudi Arabia. Blood samples from children were analyzed for hematology param...

fischer-tropsch catalysts with high activity and selectivity for olefins were produced using mordenite type sio2/al2o3= 12, 20, 28, 62 zeolite supported iron carbonyl compounds and were characterized by x-ray powder diffraction. the adsorptionof volatile fe(co)5 on the support surface was carried out under vacuum at room temperature. reduction les were monitored by vibrating sample magnetometer...

BACKGROUND/AIMS The pathogenesis of non-alcoholic steatohepatitis (NASH) is poorly understood. Hepatic iron and copper overload can directly cause lipid peroxidation and eventually hepatic damage. The aim of this study was to investigate the role of hepatic iron and copper accumulation in the development of NASH. METHODS Fifty-three patients with NASH were studied. All patients underwent live...

OBJECTIVE Oxidative stress is characterized by an increased concentration of oxygen free radicals which can cause a critical, or even an irreversible, cell injury. The study was designed to determine and compare the levels of oxidative stress and iron indices in Coronary Heart Disease and healthy individuals. MATERIAL AND METHODS Blood malondialdehyde, iron, total iron-binding capacity, trans...

The condition of hereditary hemochromatosis (HH) is caused by gene-dependent protein abnormalities involved in iron absorption, storage, or modulation of iron; these abnormalities result in iron overload. The clinical laboratory plays a significant role in case finding, diagnostic validation, and monitoring HH therapy. Elevated serum iron, transferrin saturation, and ferritin suggest HH, but re...

The mechanism whereby deferoxamine (DF) inhibits the growth of malaria parasites was studied in rats infected with Plasmodium berghei. Peak parasitemia was 32.6% (day 14) in untreated controls and 0.15% (day 7) in rats receiving 0.33 mg/g in 8 hourly DF injections, subcutaneously. DF inhibition of parasite growth was achieved without any reduction in transferrin saturation or hemoglobin synthes...
