Iron chlorosis is a very common disorder of crops grown in calcareous soils. It is well known that the total iron concentration in leaves is not a valid index for iron nutritional status of crops and that the total iron concentration in chlorotic leaves are often similar or even greater than in the green leaves. In this study, we compare three extraction methods for iron deficiency diagnosis in...

Iron metabolism is tightly regulated in osteoblasts, and ferroportin 1 (FPN1) is the only identified iron exporter in mammals to date. In the present study, the regulation of FNP1 in human osteoblasts was investigated following various iron treatments. The human osteoblast cell line hFOB 1.19 was treated with ferric ammonium citrate (FAC) or desferrioxamine (DFO) of various concentrations. The ...

Little is known about the expression of heme transporters in human placenta and possible associations between these transporters and maternal or neonatal iron status. To address this area of research, relative protein expression of 2 heme transporters, Feline Leukemia Virus, Subgroup C, Receptor 1 (FLVCR1) and Breast Cancer Resistance Protein (BCRP), was assessed using Western-blot analysis in ...

The transition metal iron is catalytically highly active in vitro, and not surprisingly, body iron has been suggested to promote oxidative stress in vivo. In the current analysis we studied the association of serum ferritin concentration and serum soluble transferrin receptor concentration with daily urinary 8-hydroxydeoxyguanosine excretion, a marker of oxidative stress, in 48 mildly dyslipide...

Glass cell experiments were conducted to investigate kinetics of iron sulfide and mixed iron sulfide/carbonate scale precipitation in CO2/H2S corrosion. Weight gain/loss (WGL) method was used to investigate the scale formation using X65 carbon steel as substrates. Scanning Electron Microscopy (SEM/EDS), X-ray Diffraction methodology (XRD), X-ray Photoelectron Spectroscopy (XPS), and Electron Pr...

The role of iron overload as cause of liver dysfunction has never been studied in detail in patients without concomitant hepatotropic infections who receive multiple transfusions. We therefore investigated the relationship between the extent of hepatocellular injury as reflected by serum levels of aminotransferases (alanine aminotransferase [ALT] and aspartate aminotransferase [AST]) and severa...

OBJECTIVES To evaluate the efficacy and safety of intravenous iron, focusing primarily on its effects on haemoglobin, requirement for transfusion, and risk of infection. DESIGN Systematic review and meta-analysis of randomised controlled trials investigating the safety and efficacy of intravenous iron therapy. DATA SOURCES Randomised controlled trials from Medline, Embase, and the Cochrane ...

this study presents a comparison between aluminum and iron plate electrodes on phosphate removal from aqueous solutions by electrocoagulation process. the effectiveness of main operational parameters such as initial ph, initial phosphate concentration and current density were examined. in addition, treated solution and sludge characteristics, energy consumption and electrode mass depletion were...

conclusions in spite of what the parents believe, iron supplements not only do not cause dental carries but also they have preventive and inhibitory effects on them. furthermore, it is highly recommended that supplements containing both iron and zinc elements should be preferred over supplements containing only iron elements. materials and methods the antimicrobial effects of six different type...

Background: Iron deficiency anemia is one of the important problems during pregnancy.  Iron deficiency has several adverse effects on pregnant women and their newborns. Objective: To determine the status of iron store in newborns born to mothers with iron deficiency anemia. Methods: In a cross-sectional study, 90 mothers were categorized into three groups according to their pre-delivery hemoglo...
