1. The effect of supplementing sow and piglet diets with different forms of iron
ABSTRACT The objective of this study was to evaluate the effect of chelated iron supplementation on gestating and lactating sows and on their suckling and weaned piglets. Reproductive traits, piglet performance, hematological parameters, and the iron concentrations in colostrum, milk, and stillborn livers were measured. Ninety-six sows were subjected to one

2. Screening of iron-enriched fungus from natural environment and evaluation of organically bound iron bioavailability in rats
Iron is an essential element for nearly all living organisms, and its deficiency is the most common form of malnutrition in the world. The organic forms of trace elements are considered more bioavailable than the inorganic forms. Although Saccharomyces cerevisiae can enrich metal elements and convert inorganic iron to organic species, its tolerability and tr

3. Efeito de fontes dietéticas de ferro sobre o desempenho de reprodutoras pesadas e conteúdo de ferro no ovo / Dietary effects of iron sources on broiler breeders performance and egg iron contents
O objetivo deste estudo foi comparar dietas com ou sem adição de farinha de carne e ossos e diferentes fontes de suplementação de ferro (Fe) em dietas para matrizes de corte. Sessenta matrizes de corte Cobb, 22 semanas de idade, foram alojadas individualmente em gaiolas e alimentadas com uma dieta (15,6% PB, 2.840 kcal EM /kg, 3,2% Ca, 0,45% de fósforo

4. Optimization of fenton s reaction aiming at in-situ and ex-situ groundwater remediation / Otimização da reação de fenton visando aplicações na remediação in-situ e ex-situ de aguas subterraneas
O desenvolvimento e a aplicação de reações de Fenton modificadas (RFM) baseadas na mistura de sais de ferro e presença de diferentes complexantes (ligantes), foram conduzidos investigando-se a influência dessas variáveis e do pH, em diferentes proporções molares Fe: H2O2:ligante. Os ligantes estudados foram os ácidos cítrico (AC), tartárico (AT),

5. Chemical absorption of H2S for biogas purification
This work presents an experimental study of purification of a biogas by removal of its hydrogen sulphide (H2S) content. The H2S was removed by means of chemical absorption in an iron-chelated solution catalyzed by Fe/EDTA, which converts H2S into elemental sulphur (S). Preparation of the catalyst solution and the results of biogas component absorption in the

6. Efeito da suplementação dietética com micro minerais orgânicos na produção e qualidade de ovos de galinhas poedeiras / Effects of diet supplementation with organic trace minerals on production and egg quality for laying hens
A experiment was conducted to study the effect of organic trace mineral sources supplementation on egg production and quality for laying hens. It were used 8 treatments: one treatment with every trace minerals on inorganic form, one treatment with all minerals on organic form and 6 treatments where only one mineral were organic. The trace minerals were: zinc

7. Determination of chelated iron in the urine
A simplified wet-ashing technique is described for the determination of chelated iron in the urine, with special reference to DTPA-bound iron. The procedure dispenses with the need for quantitative transfer, and gives corresponding economy in time, labour, and glassware without loss of precision. The standard error of the mean estimate of a triplicate determ

8. Serum ferritin in children with thalassaemia regularly transfused
A controlled trial of continuous chelation therapy in regularly transfused children with homozygous β-thalassaemia has been in progress at the Hospital for Sick Children since April 1966. In the sixth and seventh years of the trial the effect of this treatment on iron overload has been assessed by estimating serum ferritin levels and liver iron concentratio

9. Iron uptake from ferrichrome A and iron citrate in Ustilago sphaerogena.
Double radioactive label transport assays with iron, chromium, and gallium chelates were used to investigate the mechanism of iron uptake by Ustilago sphaerogena. In iron-deficient cells, ferrichrome A iron was taken up without appreciable uptake of the ligand. Iron-sufficient cells partially accumulated the ligand with the metal. The chromium- and gallium-c

11. Effect of iron-limiting conditions on growth of clinical isolates of Acinetobacter baumannii.
Different clinical isolates of Acinetobacter baumannii, typed by plasmid profile, were able to grow in iron-chelated medium by secreting iron-regulated siderophores. This iron-scavenging phenotype was associated with the production of iron-repressible catechol. Siderophore utilization bioassays showed the presence of 2,3-dihydroxybenzoic acid in the growth m

12. Effect of iron on the biodegradation of petroleum in seawater.
The biodegradation of South Louisiana (SL) crude oil and the effects of nitrogen, phosphorus, and iron supplements on this process were compared in a polluted (10,900 oil degraders per liter) and in a relatively clean (750 oil degraders per liter) littoral seawater sample taken along the New Jersey coast. Without supplements, the biodegradation of SL crude o
