  1. 1. Establishing the molecular mechanism of sodium/proton exchangers

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Povilas Uzdavinys; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; membrane protein; secondary active transporters; sodium proton exchangers; proton transport; structure; energetics; biokemi; Biochemistry;

    Abstract : Sodium/proton exchangers are ubiquitous secondary active transporters that can be found in all kingdoms of life. These proteins facilitate the transport of protons in exchange for sodium ions to help regulate internal pH, sodium levels, and cell volume. READ MORE

  2. 2. Structural and Functional Studies of Nutrient and Drug Uptake Systems

    University dissertation from Stockholm : Karolinska Institutet, Dept of Medical Biochemistry and Biophysics

    Author : Fatma Guettou; Karolinska Institutet.; Karolinska Institutet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Orally ingested nutrients and drugs are selectively absorbed from our small intestines into the bloodstream through various membrane-integrated transporters. The present study focuses mainly on a specific absorption route, namely the proton dependent oligopeptide transporters (POTs). READ MORE

  3. 3. Transport of sodium and protons in the human placenta. Mechanisms in normal pregnancy and alterations in intrauterine growth restriction

    University dissertation from Göteborg

    Author : Martin Johansson; Göteborgs universitet.; Gothenburg University.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; placenta; Na K ATPase; Na H exchanger; H K ATPase; intrauterine growth restriction; BeWo cells; epithelial transport;

    Abstract : The syncytiotrophoblast cell of the human placenta represents the interface between maternal and fetal blood supplies. This polarized epithelium consists of a maternal facing microvillous membrane (MVM) opposing a fetal facing basal membrane (BM). This unique syncytial cell is responsible for transfer of all nutrients to the developing fetus. READ MORE

  4. 4. Appetite control : genetic, immunological and neurobiological aspects

    University dissertation from Stockholm : Karolinska Institutet, Dept of Molecular Medicine and Surgery

    Author : Charlotte Lindfors; Karolinska Institutet.; Karolinska Institutet.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The overall goal of this thesis is to develop a better understanding of the brain’s regulation of appetite, i.e. the hypothalamic regulation of hunger and satiety signals. READ MORE
