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...

The Narrow-line Seyfert I galaxy, 1H0707-495, has been well observed in the 0.3– 10 keV band, revealing a dramatic drop in flux in the iron Kα band, a strong soft excess, and short timescale reverberation lags associated with these spectral features. In this paper, we present the first results of a deep 250 ks NuSTAR observation of 1H0707-495, which includes the first sensitive observations abo...

BACKGROUND Anaemia is a major cause of morbidity and mortality for children in Africa. The plasma protein haptoglobin (Hp) binds avidly to free haemoglobin released following malaria-induced haemolysis. Haptoglobin polymorphisms result in proteins with altered haemoglobin-binding capacity and different antioxidant, iron-recycling, and immune functions. Previous studies examined the importance o...

Background & Aims: Iron deficiency anemia is the most common kind of anemia in childhood. Iron supplements that are usually prescribed for the treatment stain teeth. The purpose of this study was an in vitro comparison of the adsorption rate of iron onto incisor primary teeth after exposure to three different Iron drops (Darupakhash, Fer–In– Sol, Shahredaru). Methods: This study was performed o...

In this study, iron reduction and concomitant biomineralization of a deep-sea iron reducing bacterium (IRB), Shewanella piezotolerans WP3, were systematically examined at different hydrostatic pressures (0.1, 5, 20, and 50 MPa). Our results indicate that bacterial iron reduction and induced biomineralization are influenced by hydrostatic pressure. Specifically, the iron reduction rate and exten...

It is recognized that iron overload is associated with excess mortality in HIV/AIDS, and that this may be due to iron acting as an HIV-1 transcriptional activator. In vitro evidence using iron chelators suggests that therapeutic iron depletion may be beneficial in HIV-1 infection. We describe the clinical course of a Caucasian man with hereditary haemochromatosis and HIV infection where a signi...

the requirement of iron insreased in growing children due to accelerating of growth.However nutritional iron intake and capacity to adopt iron deficiency are limited.it is not surprising then,that iron deficiency is most common in infants and children.therefore iron deficiency aneamia(IDA) is a topic of importance,not only for the management of individual patients but also for necessary public ...

iron oxide nanoparticles were synthesized by coprecipitation method using ammonia as precipitation agent. most researchers usually add ammonia into the iron salt solution but in this work the salt solution drop wise has been added to the ammonia and the new obtained results were compared with those of other researches. magnetic properties of nanoparticles were measured by vsm. the effect of rea...
