  2. 1. Mitochondrial Iron Metabolism : Study of mitoferrin in Drosophila melanogaster

    Author : Christoph Metzendorf; Maria Lind Karlberg; Kenneth Söderhäll; Martina Muckenthaler; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; iron; Drosophila; mitochondria; mitoferrin; ferritin; spermatogenesis; cell cycle; DFO; MRS12; Cell and molecular biology; Cell- och molekylärbiologi; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : Iron has a dualistic character. On the one hand it is essential for the life of most organisms, on the other hand it is involved in the generation of reactive oxygen species that are implicated in diseases and aging. READ MORE

  4. 2. Factors Influencing Iron Dialyzability and Uptake in In Vitro Models

    Author : Susan Salovaara; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ferric iron; iron dialyzability; Caco-2 cells; pea protein; organic acids; gastrointestinal model; transit time; iron absorption; ferrous iron;

    Abstract : The availability or iron from a meal is influenced by numerous factors. This thesis deals with three of them: organic acids, plant proteins (pea and soy), and transit time through the stomach and small intestine. READ MORE

  5. 3. Iron absorption and iron status related to diet : an experimental and epidemiological study

    Author : Per Tidehag; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; iron status; iron absorption; bioavailability; dietary fiber; phytate; calcium; radioiron; diet;

    Abstract : The absorption of iron from the diet is a major determinant of the iron status of an individual. Accurate measures of iron absorption are thus essential in the determination of the effects of diet composition on iron absorption and status. READ MORE

  6. 4. Drivers of increasing iron concentrations in freshwaters

    Author : Caroline Björnerås; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Järn; Akvatisk ekologi; Biogeokemi; Brunifiering; Iron; Freshwaters; Biogeochemistry; Brownification; Iron biogeochemistry; Browning; Freshwaters;

    Abstract : Iron (Fe) concentrations are increasing in freshwaters (lakes and streams) in Sweden, as well as in other regions in northern Europe. Together with increasing concentrations of organic matter, Fe is contributing to the ongoing browning of freshwaters, which may have serious ecological consequences and implications for ecosystem services.

  7. 5. In Vitro Availability of Iron in High-Tannin Sorghum. Effect of Enzymatic Oxidation of Phenolic Compounds

    Author : Erika Matuschek; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioavailability; catechol groups; polyphenols; polyphenol oxidase; iron; in vitro availability; tyrosinase; fruit extracts; sorghum; oxidation; tannins; galloyl groups;

    Abstract : Iron deficiency anemia is the most common nutritional disorder in the world. In low income countries, it is to a large extent caused by low bioavailability of iron in the vegetable diet. Vegetable diets contain large amounts of compounds that inhibit iron absorption, e.g. READ MORE
