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

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Staffan Berglund; Umeå universitet.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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; pediatrik; Pediatrics;

    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

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

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Michael Hoppe; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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.

    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

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Christoph Metzendorf; Uppsala universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron; Drosophila; mitochondria; mitoferrin; ferritin; spermatogenesis; cell cycle; DFO; MRS12; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi 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

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

    Detta är en avhandling från Chalmers University of Technology

    Författare :Susan Salovaara; Chalmers tekniska högskola.; Chalmers University of Technology.; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Bioengineering; iron dialyzability; iron absorption; ferric iron; ferrous iron; organic acids; pea protein; transit time; gastrointestinal model; Caco-2 cells;

    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
