1. Promoters effectiveness in the improvement in iron and zinc absorption from the rice and bean
Abstract Iron and zinc are essential micronutrients for the organism functioning and their lack can result in prejudices to human health. The information about the presence of minerals in the diet are normally referred to its total concentrations, however these values do not reproduce the fraction that might be bioaccessible for the human body. The objective

2. Dealing with iron metabolism in rice: from breeding for stress tolerance to biofortification
Abstract Iron is a well-known metal. Used by humankind since ancient times in many different ways, this element is present in all living organisms, where, unfortunately, it represents a two-way problem. Being an essential block in the composition of different proteins and metabolic pathways, iron is a vital component for animals and plants. That is why iron

3. Identification of genes expressed by Cryptococcus gattii during iron deprivation
Cryptococcus neoformans and C. gattii are pathogenic yeasts that cause life-threatening diseases in humans and animals. Iron is an essential nutrient for virtually every organism as it functions as a cofactor in numerous essential enzymatic reactions. In the literature, the competition for iron between microbes and mammalian hosts during infection is well do

4. Efeito do acetato de chumbo associado ou não ao sulfato ferroso em cérebro de ratos: análise das enzimas antioxidantes / Effect of lead acetate with or without iron sulfate in brain of rats: Analysis of antioxidant enzymes
Lead (Pb2+) is a toxic heavy metal, found in all stages of the inert environment and in several biological systems. When uptaken by the organism, acts on several organs and systems and may cause severe damage in Central Nervous System. In addition, it has been reported that iron (Fe2+) may present, a protective effect on neurotoxicity caused by Pb2+. Therefo

5. Estudo geoquímico e microfaunístico da região circunjacente ao emissário submarino de esgoto das Cigarras, São Sebastião, SP / Geochemistry and microfaunistic study of the area around the submarine outfall of Cigarras, São Sebastião, SP
The influence of submarine outfall of domestic sewage on the benthic foraminifera and sediments quality at Cigarras, São Sebastião, SP, is evaluated in this dissertation. Twenty water and bottom sediment samples were collected around the outfall in September 2006 (ten samples) and 2007 (ten samples). Another two samples were collected in the São Sebastiã

6. Impacto da doação de sangue nos depósitos de ferro do organismo de doadores
Iron is a vital element in the human metabolism. It plays a central role in erythropoiesis and is also involved in many other intracellular processes in all the tissues of the body. Blood donation results in a substantial (200 to 250 ng) loss of iron at each donation (425 to 475 ml) with subsequent mobilization of iron from body deposits. Repetitive donation

7. Análises transcricionais no estudo da expressão gênica de Paracoccidioides brasiliensis em condições que mimetizam nichos do hospedeiro
Paracoccidioides brasiliensis is a fungal human pathogen with a wide distribution in Latin America. It causes paracoccidioidomycosis, the most widespread systemic mycosis in Latin America. The fungus causes infection through host inhalation of airborne propagules of the mycelial phase of the organism. These particles reach the lungs, and disseminate to other

8. Avaliação morfológica de baço, linfonodo e fígado de macacos-prego cebus apella tratados com nanopartículas magnéticas recobertas com DMSA
Magnetic fluids (MF) are colloidal suspensions formed by magnetic iron oxide nanoparticles (MNPs) such as magnetite (Fe3O4) and maghemite ( Fe2O4), dispersed in a liquid medium. In recent years, the use of magnetic fluid has been suggested as a promising tool for various biomedical applications; however, it is necessary to evaluate the effects caused by the

10. OXIDATIVE STRESS IN HEMODIALIZED PATIENTS AND THE INFLUENCE OF TERAPEUTIC TREATMENT / O ESTRESSE OXIDATIVO EM PACIENTES HEMODIALISADOS E A INFLUÊNCIA DO TRATAMENTO TERAPÊUTICO
The imbalance between the oxidant species formation and the activity of antioxidants is known as oxidative stress and it is directly related to the etiology and/or the progression of chronic diseases such as chronic renal failure (CRF), atherosclerosis and cardiovascular diseases. The CRF can be the result of variety renal injuries that lead to toxic substan

11. EFEITO DO EXCESSO DE FERRO E DIETA HIPERCOLESTEROLÊMICA SOBRE O PERFIL DE LIPÍDIOS SÉRICOS E ESTRESSE OXIDATIVO EM HAMSTERS
O aumento nos níveis de LDL e a diminuição de HDL têm sido apontados como fatores de risco para a aterosclerose e contribuído para o desenvolvimento de doenças cardiovasculares (DCV). Por outro lado, estudos epidemiológicos e experimentais sugerem que o excesso de ferro, também, pode contribuir para o desenvolvimento dessas doenças. O objetivo do tr

12. Deficiência de ferro em doadores de sangue
Iron deficiency continues to be an important problem worldwide. As a synthetic alternative has not been found until now blood donation remains indispensable. But blood donation can cause a substantial reduction of iron in the organism of the donor. Here we wish to bring attention to this in order to improve the quality of the donated blood and to preserve th
