  1. 6. Net-Charge Fluctuations in Ultra-Relativistic Nucleus-Nucleus Collisions

    Författare :Henrik Tydesjö; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quark-Gluon Plasma; Net-Charge Fluctuations; Pad Chamber; högenergi; Kosmisk strålning; High energy interactions; cosmic rays; PHENIX; Heavy-Ion Collisions; RHIC; Fysicumarkivet A:2004:Tydesjö;

    Sammanfattning : PHENIX is one of four experiments at the Relativistic Heavy-Ion Collider, RHIC. The high-energy heavy-ion collisions provided by this accelerator offer the possibility to study nuclear matter at high temperature and density. The high multiplicity of particles produced in these collisions puts high demands on detector performance. LÄS MER

  3. 7. Taste Hedonics and the Intake of Alcohol and Food

    Författare :Anna Söderpalm; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Alcohol drinking; Adrenalectomy; Corticosterone; Cyanoketone; Food intake; Food restriction; GABA; Metyrapone; Taste reactivity; Benzodiazepine; Chlordiazepoxide; Cis Z -flupentixol; Diazepam; Flumazenil; Microinjections; Midazolam; Nucleus of the Solitary tract; Palatability; Parabrachial nucleus; Peduculopontine Tegmental Nucleus; Reward; 4th ventricle.;

    Sammanfattning : This thesis includes four papers based on animal experimental work. They analyze the way in which activation of a specific motivational state - hunger- modulates the rewarding actions of alcohol and taste palatability. LÄS MER

  4. 8. Nitric oxide in central nervous structures associated with water balance and micturition

    Författare :Anders Nylén; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacological sciences; spinal projections; True Blue; cystometry; circumventricular organs; paraventricular nucleus; supraoptic nucleus; NADPH diaphorase; immunohistochemistry; oxytocin; 8-arginine-vasopressin; hypothalamus; rat; micturition; nitric oxide; water balance; neuronal nitric oxide synthase; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : The role of nitric oxide (NO) in the central control of water balance and micturition has not yet been established. In the present thesis, where female rats were used, neuronal NO synthase (nNOS) distribution was studied in structures of the central nervous system known to be associated with the above mentioned control.

  5. 9. The evolution of the nuclear envelope

    Författare :Nadja Neumann; Anthony Poole; Gáspár Jékely; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear pore complex; bouquet; meiosis; nucleus; eukaryote evolution; nucleoporin; tree of life; stem group; recombination; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : The nucleus is one of the defining features of eukaryotes and the question of its origin is intimately linked to the evolution of the eukaryotic cell. It is delimited by a double lipid bilayer called the nuclear envelope, which separates the nuclear interior from the cytoplasm. LÄS MER

  7. 10. Functional studies of nuclear envelope-associated proteins in Saccharomyces cerevisiae

    Författare :Ida Olsson; Ann Mutvei; Valérie Doye; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nucleus; nuclear envelope; nuclear pore complexes; vesicular traffic; arginine methylation; Rmt2; Cwh43; Myr1; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Proteins of the nuclear envelope play important roles in a variety of cellular processes e.g. transport of proteins between the nucleus and cytoplasm, co-ordination of nuclear and cytoplasmic events, anchoring of chromatin to the nuclear periphery and regulation of transcription.
