OBJECTIVES The purpose of this work was to assess the effect of severe maternal iron-deficiency anemia and nutritional status on cord blood and breast milk iron status. METHODS We conducted a prospective observational study over a 6-month period in a teaching hospital in central India. The study population consisted of 55 anemic (hemoglobin: < 110 g/L) and 20 healthy nonanemic (hemoglobin: > ...

Iron is an indispensable element for plant growth and defense and hence it is essential to improve the plant's ability to accumulate iron. Besides, it is also an important aspect for human health. In view of this, we attempted to increase the iron content in banana cultivar Rasthali using MusaFer1 as a candidate gene. Initially, the expression of all five genes of the MusaFer family (MusaFer1-5...

-1. The iron content of whole milk and the distribution of iron between fractions separated by centrifugation was determined on milk obtained from lactating laboratory rats (Rattus norvegicus), rabbits (Oryctolagus cuniculus) and quokkas (Setonix brachyurus) at various stages of lactation. In rat milk, the distribution of 59Fe label administered in vivo or added in vitro was also studied. 2. Mi...

An automated procedurehas been developedfordeterminingserum iron content and iron-binding capacity with a new iron-chelating ligand, a 5. pyridyl.benzodiazepin-2-one derivative. A simplified manifoldand flowsystem, together with improved reagent combinations, offer distinct advantages over existing automated procedures. The results obtained by auto. mated analysis for serum iron and iron-bindin...

Iron is ubiquitous in the environment and in biology. The study of iron biology focuses on physiology and homeostasis-understanding how cells and organisms regulate their iron content, how diverse tissues orchestrate iron allocation, and how dysregulated iron homeostasis leads to common hematological, metabolic, and neurodegenerative diseases. This has provided novel insights into gene regulati...

The effect of iron oxide content on the crystallisation of a diopside glass–ceramic glaze was investigated using a glass–ceramic frit in the K2O–ZnO–MgO–CaO–Al2O3–SiO2 system and a granite waste glass. Measurements by X-ray diffraction (XRD) combined with scanning electron microscopy (SEM) and EDX microanalysis showed that the distribution of Fe ions among different crystalline phases such as f...

High-pressure oxygen fugacity (‘redox’) sensors are widely used to make estimates of the effective concentration of oxygen in experimental petrology. They typically rely on iron either diffusing into a nominally iron free mineral (e.g. iron into magnesiowüstite [1]) or iron alloying with a noble metal[2, 3]. In both cases the iron content of the sensor material should reflect the prevailing oxy...

Transferrin receptor (TfR) expression is regulated by iron at the level of mRNA stability through a factor (IRF/IRE-BP) which binds to specific iron-responsive elements (IRE). On the other hand, growth-dependent regulation of TfR expression is generally believed to be transcriptionally controlled. We analyzed the molecular mechanisms that control TfR gene expression at the onset of cell prolife...

Analyses of commercial crude sOYbean oils showed a highly significant correlation of 0.74 betwee~ free fatty acid and iron content. Poor flavor characteristics exhibited by finished oils extracted from damaged beans may be caused in part by a higher free fatty acid and related higher iron content in crude oils. Source of the increased iron appears to be both damaged beans and steel processing e...
