  1. 1. Retinal glucose metabolism and blood flow : Effects of photic stimulation

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lin Wang; Uppsala universitet.; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; blood flow; darkness; flicker; glucose oxidation; glycolysis; lactate; light; nitric oxide; optic nerve; retina; Fysiologi och anatomi; MEDICINE Physiology and pharmacology; MEDICIN Fysiologi och farmakologi; fysiologi; Physiology;

    Sammanfattning : Retinal glucose metabolism was investigated under different light conditions in cats,pigs and rabbits. Glycolysis and glucose oxidation in the outer and inner parts of theretina were assessed by determining arteriovenous concentration differences foroxygen, glucose and lactate, as well as local blood flow.

  2. 2. Glucose and lipid metabolism in insulin resistance an experimental study in fat cells

    Detta är en avhandling från Umeå : Folkhälsa och klinisk medicin

    Författare :Jonas Burén; Umeå universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Public health; adipocyte; insulin resistance; type 2 diabetes; insulin signalling; glucose uptake; insulin; glucose; dexamethasone; insulin receptor substrate; protein kinase B; GLUT4; lipoprotein lipase; Folkhälsomedicin; MEDICINE Social medicine Public health medicine research areas; MEDICIN Socialmedicin Folkhälsomedicinska forskningsområden; medicin; Medicine;

    Sammanfattning : Type 2 diabetes is usually caused by a combination of pancreatic β-cell failure and insulin resistance in target tissues like liver, muscle and fat. Insulin resistance is characterised by an impaired effect of insulin to reduce hepatic glucose production and to promote glucose uptake in peripheral tissues. LÄS MER

  3. 3. Quantitation, Purification and Reconstitution of the Red Blood Cell Glucose Transporter GLUT1

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Shusheng Zuo; Uppsala universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Cholesterol; Cytochalasin B; Glucose; GLUT1; Hummel and Dreyer analysis; Immobilization; PEG 5000 -DSPE; Biomembrane; Proteoliposome; Quantitative frontal affinity chromatography; Red blood cell streptavidin-biotin immobilization; Sulfhydryl affinity chromatography; The modified micro-Bradford CaPE assay; MALDI-ToF-MS; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi;

    Sammanfattning : The human glucose transporter GLUT1 facilitates glucose to be accumulated on the other side of the cell membrane. The functional state of GLUT1 is uncertain due to diversity of the reports. In this thesis, the activity of red blood cell GLUT1 was extensively studied to further characterize this protein. LÄS MER

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Affinity; Aromatic amino acids; Binding; Biomembrane; Biotin; Chromatography; Cytochalasin B; Dihydrocytochalasin B; Dissociation constant; Drug absorption; Ethanol; Equilibrium; Glucose; GLUT1; Immobilization; Immobilized biomembrane affinity chromatography; Immobilized liposome chromatography; Interaction; Liposome; Membrane protein; Membrane vesicle; Partitioning; Phospholipid bilayer; Proteoliposome; Quantitative; Red blood cell; Specific; Streptavidin; Tyrosine; Tryptophan; Biokemi; MEDICINE Chemistry Biochemistry; MEDICIN Kemi Biokemi;

    Sammanfattning : The human glucose transporter GLUT1 is abundant in red blood cells, the blood-brain barrier and epithelial cells, where it mediates the transport of the energy metabolite, glucose. In the present work some properties of GLUT1, including affinity binding of both substrates and inhibitors, transport rates as well as permeabilities of aromatic amino acids and drug-membrane interactions were analyzed by chromatographic methods.

  5. 5. Chromatographic Studies of Solute Interactions with Immobilized Red Blood Cells and Biomembranes

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ingo Gottschalk; Uppsala universitet.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Affinity; Binding; Biomembrane; Biotin; Chromatography; Cytochalasin B; Dissociation constant; Drug absorption; Equilibrium; Glucose; GLUT1; Immobilization; Immobilized biomembrane affinity chromatography; Immobilized liposome chromatography; Interaction; Liposome; Membrane protein; Membrane vesicle; Partitioning; Phospholipid bilayer; Proteoliposome; Quantitative; Red blood cell; Solute; Specific; Streptavidin; Wheat germ agglutinin; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; Biokemi; Biochemistry;

    Sammanfattning : Specific and non-specific interactions of solutes with immobilized biomembranes were studied using chromatographic methods. Liposomes, proteoliposomes and red blood cell (RBC) membrane vesicles were immobilized by a freeze-thawing procedure, whereas whole RBCs were adsorbed in the gel beds using electrostatic interaction, binding to wheat germ agglutinin (WGA) or the streptavidin-biotin interaction.
