1. The uptake of different iron salts by the yeast Saccharomyces cerevisiae
Yeasts can be enriched with microelements, including iron; however, special physicochemical conditions are required to formulate a culture media that promotes both yeast growth and iron uptake. Different iron sources do not affect biomass formation; however, considering efficacy, cost, stability, and compatibility with Saccharomyces cerevisiae metabolism, fe

2. Ferritin gene expression and antioxidant response of two Coffea arabica cultivars exposed to iron and aluminium / Expressão de genes da ferritina e resposta antioxidante em duas cultivares de Coffea arabica expostas a ferro e aluminio
Ferritin is a protein capable to store iron (Fe) atoms in a nontoxic form, controlling the level of this metal in the cells. In humans, ferritin is able to accommodate aluminium (Al) atoms, avoiding its toxicity. Considering that Coffea arabica plants are able to grow well in acidic soils with high Al and suspension cells treated with this same metal showed

3. Produção de sulfato ferroso a partir de rejeitos de carvão
A mineração de carvão gera grandes volumes de rejeitos que podem ser responsáveis por graves danos ambientais. A oxidação da pirita (FeS2), na presença de ar e água, promove a formação da drenagem ácida de mina (DAM), uma solução aquosa fortemente ácida e rica em sulfato e ferro (nas formas Fe²+ e Fe³+), além de outros metais associados. Atu

4. Efeito da adição de Glutationa na função e estresse oxidativo em sêmen ovino criopreservado / Effect of glutathione on ovine cryopreserved sperm function and oxidative status
It is well known that sperm is extremely susceptible to the oxidative stress. This occurs especially due to the high content of poly-unsaturated fatty acids (PUF As) in its plasma membrane. The PUF As provide the necessary fluidity to the plasma membrane, which allows the sperm to move. However the double bonds present in those fatty acids are more susceptib

5. Viability of artificial diets and preys for Eriopis connexa (Germar) (Coleoptera: Coccinellidae) / Viabilidade de dietas artificiais e presas para Eriopis connexa (Germar) (Coleoptera: Coccinellidae)
This research was conducted in the Laboratory of Insects Rearing (LACRI), of the Brazilian Company of Agricultural Research (EMBRAPA Maize and Sorghum Research Center) in Sete Lagoas, Minas Gerais State, Brazil. The objective was to study biological aspects of the immature phase of Eriopis connexa (Germar) (Coleoptera: Coccinellidae), with different artifici

6. Avaliação do programa nacional de suplementação de ferro no controle de anemia, em crianças de 6 a 24 meses, assistidas nos centros de educação infantil do município do Guarujá / Evaluation of the national control program of iron-deficiency anemia suplementation in 6 to 24-month-old children, attended by public nursery services
The iron-deficiency anemia in children is a major nutritional problem faced by developing countries. The National Program of Iron Supplementation established in Brazil in 2005, which seeks to control this nutritional deficiency, consists of weekly supplementation of iron, distributed freely in health care centers, for 6 to 18-month-old children. Objective: T

7. Analise da expressão de genes que codificam proteinas transportadoras em Acidithiobacillus ferrooxidans e Acidithiobacillus thioxidans na presença de sulfetos metalicos / Expression analyses of genes that encode for transporter protein in Acidithiobacillus ferrooxidans and Acidithiobacillus thioxidans maintained in contact with metal sulphiides
Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans are acidophilic, chemolitotrophic and mesophilic bacteria found in bioleaching environments. A. ferrooxidans uses ferrous iron and sulphur compounds as an e1ectron donor and A. thiooxidans uses on1y sulphur and sulphur compounds. Both species are aerobic using oxygen as final e1ectron acceptor.

8. Evaluation of impact of the National Program of Iron Supplementation on non anemic infants, Viçosa, MG / Avaliação do impacto do Programa Nacional de Suplementação de Ferro em lactentes não anêmicos,Viçosa, MG
The limited success of prophylaxis programs of iron deficiency anemia on infants force to the need of programs evaluation researches in order to improve health public policies related to that lack. On this way, this work aimed to evaluate the impact of the National Program of Iron Supplementation on non anemic infants from 6 to 18 months of age (PNSF) attend

9. Estabilidade físico-química de ácido fólico em farinha de milho fortificada
The pteroylglutamic acid, also called folic acid or folate, is one water-soluble B vitamins. Studies have found that women who take folic acid supplements before conception and during the first trimester, may reduce their risk of having children with neural tube defects by 75%. In 2004, the ANVISA, the Brazilian Health Surveillance Agency obligated the addit

10. Papel do molibdÃnio na anemia da infÃncia
Three hundred and twenty nine (329) children of 1 to 6 years of age, of 6 day-care centers of the city of Recife, had been submitted to a initial evaluation of the nutritional state of iron using hemoglobin levels and, divided in 3 groups, received, during 30 days, 500μg of supplements of molybdenum and 15mg of ferrous sulphate (SFMO â 91 children), or

11. Iron lung: bronchoscopic and pathological consequences of aspiration of ferrous sulphate.
Acute bronchial damage was caused by aspiration of a ferrous sulphate tablet, early histological changes (unlike in the few previously reported cases) being observed in the biopsy specimens.

12. Influence of iron preparations on occult blood tests
Ferrous fumarate (Fersamal) and ferrous carbonate (Ferrodic) may produce false-positive results with the orthotolidine tablet tests (Occultest and Hematest) if administered to patients being investigated for alimentary bleeding. Misleading results are also likely if the benzidine test is employed as a filter-paper procedure. Ferrous sulphate, gluconate, succ
