  1. 1. Effects of iron supplementation on iron status, health and neurological development in marginally low birth weight infants

    Författare :Staffan Berglund; Magnus Domellöf; Olle Hernell; Michael K Georgieff; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Auditory brainstem response; behavior; breast feeding; cognition; erythropoietin; ferritin; growth; hemoglobin; hepcidin; human infant; iron; iron deficiency; iron deficiency anemia; iron status; iron supplementation; low birth weight; morbidity; neurodevelopment; nutritional requirements; randomized controlled trial; Pediatrics; pediatrik;

    Sammanfattning : Background Due to small iron stores and rapid growth during the first months of life, infants with low birth weight (LBW) are at risk of iron deficiency (ID). ID in infancy is associated with irreversible impaired neurodevelopment. LÄS MER

  3. 2. Iron absorption in man - diet modification and fortification

    Författare :Michael Hoppe; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Iron absorption; Serum iron; Relative bioavailability; Elemental iron; Iron bioavailability; Iron fortification; Dietary modification; Developing countries;

    Sammanfattning : Background: Iron (Fe) deficiency is globally the most common form of nutrient deficiency. The approach to combat this problem can be divided into two major strategies a): increasing the dietary Fe bioavailability by diet modification, or b): increasing the Fe intake through fortification.

  4. 3. Iron Losses in Electrical Machines - Influence of Material Properties, Manufacturing Processes, and Inverter Operation

    Författare :Andreas Krings; Juliette Soulard; Oskar Wallmark; Annette Mütze; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AC machines; cobalt-iron; eddy current losses; electrical steel sheets; inverter-fed machines; iron alloys; iron loss measurements; machine design; magnetic hysteresis; magnetic losses; magnetic materials; nickel-iron; permanent magnet machines; silicon-iron; soft magnetic composites; slot-less machines; soft magnetic materials; thermal effects.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : As the major electricity consumer, electrical machines play a key role for global energy savings. Machine manufacturers put considerable efforts into the development of more efficient electrical machines for loss reduction and higher power density achievements. LÄS MER

  5. 4. Mitochondrial Iron Metabolism : Study of mitoferrin in Drosophila melanogaster

    Författare :Christoph Metzendorf; Maria Lind Karlberg; Kenneth Söderhäll; Martina Muckenthaler; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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;

    Sammanfattning : 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. LÄS MER

  7. 5. Factors Influencing Iron Dialyzability and Uptake in In Vitro Models

    Författare :Susan Salovaara; Chalmers University of Technology; []
    Nyckelord :ferric iron; iron dialyzability; Caco-2 cells; pea protein; organic acids; gastrointestinal model; transit time; iron absorption; ferrous iron;

    Sammanfattning : 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. LÄS MER
