Six male and three female patients previously iron deficient after a partial gastrectomy were investigated using a whole body counter to measure their percentage (59)Fe retention. No significant difference in iron loss between postgastrectomy patients and controls was found in the majority of subjects over a study which lasted from 175 to 225 days. The detection of increased free iron loss requ...

In view of the erythroid hyperplasia found in the bone marrow of subjects with chronic iron deficiency anemia, the delayed appearance of reticulocytosis following iron therapy is unexplained. Profound disturbances were observed in some biochemical functions of the bone marrow cells isolated from such patients. There was a substantial decrease in the cellular nucleic acid content, associated wit...

In the absence of iron, dissolution of zinc sulfide was enhanced by the action of Acidithiobacillus caldus at 40 o C. The bioleaching mechanism was similar to that observed for mesophilic species of Acidithiobacillus at 30 o C, although the final metal recovery was lower. When iron was added to the cultures, the solubilization of zinc and copper from the sulfides was higher than that in sterile...

Introduction Therapeutic cell treatments have been applied to a large number of pathological diseases. Tracking the engraftment of cells is key to planning and assessing cell therapies. Migration dynamics and tissue integration are commonly assessed by locating iron-oxide labeled cells with T2* weighted MRI. Interpretation of the resulting signal voids can be challenging in preclinical scanners...

The presence of inorganic or organic iron in the growth medium induces the production of a reddish-violet pigment in Micrococcus violagabrielhe. This pigment protects the organism against short exposures to ultraviolet (u.v.) radiation of wavelength below 300 mp. The presence of iron also increases the degree of recovery of the normally white organism after such irradiation. Anaerobic growth re...

A simple experiment was performed to ascertain whether proceduresfor estimating the iron-binding capacity (IBC) of blood serum are quantitative. This was accomplishedby addingf3-globulin (obtained by fractionation of human plasma) to various serum specimens. The 3-globulin solutionswere first assayedfor their IBC. Their addition to serum in these recovery experiments provided data for evaluatio...

TO THE EDITOR—We read with interest the article by Minchella and colleagues, who prospectively studied anemia (baseline prevalence, 67%) in patients with tuberculosis in TheGambia [1].Although themost common etiology was immune-mediated anemia of chronic disease (ACD), iron deficiency anemia (IDA) and combined anemia (ACD + IDA) were also frequently observed. Whereas ACD typically resolved with...

Acid-fast bacilli from pediatric patients with lymphadenopathy were detected in the BACTEC radiometric system and in MB Redox broth, but not on Löwenstein Jensen medium. PCR amplification identified the isolates as Mycobacterium haemophilum, which has special nutrition requirements (iron supplements) for growth. Suitable culture medium ensures optimal recovery of this microorganism, avoiding un...

Claims are often found in the literature that metallic materials can be nanocrystallized by severe plastic deformation (SPD). However, SPD does not generate a well-defined nanocrystalline (NC) material, which can be achieved by subsequent annealing/recovery treatment. In this study, molecular dynamics (MD) simulation is employed to study the effect of annealing on structure and mechanical prope...

different samples have been prepared from different products in chadormalu iron ore concentrator plant: low intensity magnetite separators concentrate (magnetite concentrate), reverse flotation tail (final hematite concentrate), flotation concentrate (apatite concentrate), final tail (l.i.m.s. tail + reverse flotation concentrate+ apatite flotation tail). the samples were used for rare earth el...
