  1. 11. Membrane-bound proteins : Characterization, evolution, and functional analysis

    Författare :Misty M. Attwood; Helgi B. Schiöth; Arne Elofsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transmembrane protein; alpha-helical membrane protein; evolution membrane proteins; 3TM; 4TM; 5TM; trispanin; Bioinformatics; Bioinformatik;

    Sammanfattning : Alpha-helical transmembrane proteins are important components of many essential cell processes including signal transduction, transport of molecules across membranes, protein and membrane trafficking, and structural and adhesion activities, amongst others. Their involvement in critical networks makes them the focus of interest in investigating disease pathways, as candidate drug targets, and in evolutionary analyses to identify homologous protein families and possible functional activities.

  2. 12. Synaptic organization of nociceptive relay nuclei in the cat and primate thalamus

    Författare :Ann-Charlott Ericson; Per Brodal; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The fine structure of two thalamic nociceptive relay nuclei, the nucleus submedius (Sm) in the cat, and the posterior region in the owl monkey, was investigated using anatomical tract tracing techniques, immunohistochemical staining for neuroactive substances, and threedimensional reconstructions of synaptic circuitry. Ascending lamina I axons, labeled by anterograde transport of Phaseolus vulgaris leucoagglutinin, gave rise to two different types of termination in Sm: large, compact clusters of numerous boutons were predominant in the dense focus of the terminal field after a tracer injection at the site of nociceptive-specific neurons in lamina I, and boutons-of-passage type terminations were conspicuous in the periphery of a lamina I terminal field in Sm and predominant following a tracer injection at the site of thermoreceptive-specific neurons in lamina I.

  3. 13. To “leaf” or not to “leaf” : Understanding the metabolic adjustments associated with leaf senescence

    Författare :Daria Chrobok; Olivier Keech; Per Gardeström; David Macherel; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; metabolism; mitochondria; senescence; biology; biologi;

    Sammanfattning : The adequate execution of the final developmental stage of a leaf, leaf senescence, is crucial to the long-term survival of the plant. During senescence cellular structures like membranes, proteins, lipids and macromolecules are degraded and released nutrients are relocated to developing parts of the plant, such as young leaves, stems, flowers, siliques and ultimately seeds that are dependent on this nutrient remobilization.

  4. 14. Halomonas species as a source of poly(3-hydroxybutyrate). Preparation of hydrophilic macroporous polymer scaffolds

    Författare :Daniel Guzmán; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Halomonas species; poly 3-hydroxybutyrate ; genome sequence; Fed-batch cultivation; macroporous scaffolds;

    Sammanfattning : This thesis presents studies on moderately halophilic bacteria belonging to the family Halomonadaceae that accumulate polyhydroxybutyrate (PHB) in high amounts when grown under conditions of nitrogen limitation. PHB is the simplest homopolymer belonging to the class of polyhydroxyalkanoates (PHAs), the biopolyesters that can biodegraded in the environment to carbon dioxide and water and are hence attractive substitutes for fossil-derived plastics.

  5. 15. Characterization of Amino Acid Transporters in the Brain : Molecular and Functional Studies of Members within the Solute Carrier Families SLC38 and SLC6

    Författare :Maria Hägglund; Robert Fredriksson; Farrukh Chaudhry; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amino acid transporter; Solute Carrier; Glutamine; Leucine; SNAT; B0AT; Neuroscience; Neurovetenskap;

    Sammanfattning : Solute carriers (SLCs) comprise the largest group of transporters in humans and there are currently 52 SLC families. They are embedded in cellular membranes and transport numerous molecules; defects in many of the genes encoding SLCs have been connected to pathological conditions, and several SLCs are potential drug targets.
