    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic and optical properties; supraconductors; electrical; Rymdteknik; kosmisk kemi; Condensed matter:electronic structure; rymdvetenskap; Astronomi; cosmic chemistry; space research; Astronomy; boron; isotope shifts; Chi Lupi; fluorescence; element abundances; emission lines; GHRS; strontium; STIS; Eta Carinae; spectroscopy; Hubble Space Telescope; supraledare; magnetiska och optiska ; magnetisk resonans; Space technology; spektroskopi; relaxation; magnetic resonance; egenskaper elektriska ; Kondenserade materiens egenskaper:elektronstruktur;

    Sammanfattning : Eta Carinae is a super-massive, super-luminous star. It is surrounded by a bipolar nebula, the "Homunculus", and several blobs of ejected gas which are the source of a complex emission-line spectrum. LÄS MER

  3. 2. Laboratory and Stellar Spectra in High Resolution: Studies of Fe, Pt and Tl in Peculiar Stars

    Författare :Gabriele Kalus; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; high-resolution spectroscopy; hyperfine structure; peculiar stars; iron; platinum; lead; upsilon Sagittarii; HR7775; chi Lupi; isotope shift; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1997:Kalus;

    Sammanfattning : The near-infrared spectrum of upsilon Sagittarii has been registered using the SOFIN high resolution spectrometer on the Nordic Optic Telescope, La Palma. For the first time 4f-5g transitions of Fe II in any astrophysical spectrum have been identified. LÄS MER

  4. 3. Growth hormone and somatolactin function during sexual maturation of female Atlantic salmon

    Författare :Susana Benedet Perea; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Growth hormone; somatolactin; insulin-like growth factor I; GH; SL; IGFI; GHR; SLR; IGFIR; ovary maturation; reproduction; Atlantic salmon; spawning; pituitary;

    Sammanfattning : Background and aims: The growth hormone-insulin-like growth factor I (GH-IGF-I) system is known to act during sexual maturation of female salmonids, but the specific roles are not known. Somatolactin (SL) is a pituitary hormone closely related to GH and is only found in fish. In some species, including salmonids, there are two forms, SLa and SLß. LÄS MER

  5. 4. CNS Targets for GH and IGF-1 : Emphasis on Their Regulation in Relation to Cognitive Processes

    Författare :Madeleine Le Grevès; Fred Nyberg; Anders Hallberg; Sigbritt Werner; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical pharmacology; Central nervous system; Growth hormone; Insulin-like growth factor-1; Receptor mRNA regulation; N-methyl-D-aspartate receptor mRNA; Morris water maze; Farmaceutisk farmakologi; Pharmaceutical pharmacology; Farmaceutisk farmakologi;

    Sammanfattning : The interest for the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis and its role in the central nervous system (CNS) has grown during the past decade. GH has been associated with psychological functions as sleep, mood, general well-being and learning and memory. LÄS MER

  7. 5. Pituitary regulation of plasma lipoprotein metabolism and intestinal cholesterol absorption

    Författare :Manuela Matasconi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Increased levels of plasma cholesterol are associated with a higher risk to develop atherosclerosis, the leading cause of death in Western societies. The major part of cholesterol in human blood is transported within low-density lipoproteins (LDL-C) that bind to specific cell surface receptors (LDLRs). LÄS MER
