Bimagnetic monodisperse CoFe₂O₄/Fe₃O₄ core/shell nanoparticles have been prepared by solution evaporation route. To demonstrate preferential coating of iron oxide onto the surface of ferrite nanoparticles X-ray diffraction (XRD), High resolution transmission electron microscope (HR-TEM) and Raman spectroscopy have been performed. XRD analysis using Rietveld refinement technique confirms single ...

This article proposes a nonlinear controller based on feedback linearization (FL) for synchronous reluctance motor (SynRM) drives which takes into consideration the magnetic saturation. The proposed FL control technique has been developed starting from theoretical definition of an original dynamic model SynRM taking both self- and cross-saturation effects. Such permits dynamics speed axis flux ...

BACKGROUND Recent data shows an increased mortality risk associated with elevated transferrin saturation. Because ingestion of dietary iron may contribute to iron overload in persons with elevated transferrin saturation, we investigated the relationship between elevated transferrin saturation, ingestion of dietary iron and red meat, and mortality. METHODS This 12-year cohort study used data f...

The relationship between plasma iron, transferrin saturation, and plasma iron turnover was studied in 53 normal subjects whose transferrin saturation varied between 17% and 57%, in 25 normal subjects whose transferrin saturation was increased by iron infusion to between 67% and 100%, and in five subjects with early untreated idiopathic hemochromatosis whose transferrin saturation was continuall...

To multiply and cause disease in the host, Mycobacterium tuberculosis must acquire iron from the extracellular environment at sites of replication. To do so, the bacterium releases high-affinity iron-binding siderophores called exochelins. In previous studies, we have described the purification and characterization of the exochelin family of molecules. These molecules share a common core struct...

Iron deficiency anemia(IDA) is one of the most common nutritional problems in the world.children under 5 years old are considerd as the high risk group consisting a high proportion of IDA patients.in this group,due to the specific conditions,the complication of anemia may lead to serious consequences.this study was designed to determine the prevalence of IDA in 1-5 years old children.A total of...

erythropoietin. Transferrin saturation is a good indicator of the current balance of supply and demand of plasma iron, although it is an inadequate indicator of the amount of iron stored. In addition, Bainton and Finch showed that once the transferrin saturation falls below 16% iron supply for erythropoiesis may be inadequate.4 Our data also suggest that, during treatment with erythropoietin, m...

Determination of the reticulocyte hemoglobin content (CHr) provides an early measure of functional iron deficiency because reticulocytes are the earliest erythrocytes released into blood and circulate for only 1 to 2 days. The CHr in 78 patients undergoing bone marrow examination was measured to assess its clinical utility for the diagnosis of iron deficiency. Twenty-eight patients were iron de...
