  1. 6. Nestin : filament formation and expression in myogenesis and muscle disorders

    Författare :Gunnar Sjöberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Intermediate filament; nestin; desmin; vimentin; myogenesis neuromusculardisorders; rhabdomyosarcoma;

    Sammanfattning : Intermediate filaments (IF), together with microfilaments and microtubules, are the major components of the cytoskeleton of eukaryotic cells. In myogenic cells three IF proteins are expressed; desmin, vimentin and nestin. LÄS MER

  3. 7. Salivary gland neoplasms : studies on the cytoskeleton, the secretory apparatus and the nuclear DNA content

    Författare :Hans Gustafsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salivary gland neoplasms; intermediate filaments; immuno- histochemistry; ultrastructure; DNA; development; histogenesis; progno¬sis;

    Sammanfattning : The heterogeneity of salivary gland neoplasms have made classification and prognostication of these tumours sometimes difficult, and the in­troduction of techniques, such as enzyme and carbohydrate histochemis­try and electron microscopy have only to a certain extent increased our knowledge in these respects. In the present study immunohistochemical methods have been used to identify intermediate filament proteins (IFP) in normal fetal and adult parotid glands, as well as in salivary neo­plasms. LÄS MER

  4. 8. Platelet-derived growth factor-induced signal transduction

    Författare :Sigrídur Valgeirsdóttir; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Cellbiologi; Cell biology; Cellbiologi; molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Platelet-derived growth factor (PDGF), a potent mitogen for mesenchymal cells, elicits its effects by binding to cell surface tyrosine kinase receptors, denoted α- and β-receptors. This thesis describes the mechanism of interaction between stimulated PDGF receptors and various intracellular molecules. LÄS MER

  5. 9. Sarcoplasmic body myopathy

    Författare :Birgitta Hedberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In 1980 a new hereditary myopathy with adult onset was described in a swedish family. The most characteristic feature of this myopathy was the sarcoplasmic inclusion bodies (SB), seen in the muscle biopsies. Distal muscle weakness seemed to be the most prominent early symptom.

  7. 10. The blind spot : inflammatory pathways and specific antigens in clinical phenotypes of pulmonary sarcoidosis

    Författare :Ylva Kaiser; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Sarcoidosis is a granulomatous multisystem disorder of unknown aetiology, primarily manifesting in the lungs. The disease appears in two forms, which are mainly distinguished based on clinical criteria; Löfgren's syndrome (LS) presents with acute onset, usually fever, active inflammation and characteristic symptoms such as bilateral hilar lymphadenopathy (BHL), erythema nodosum and/or ankle arthritis, but is also associated with spontaneous resolution and a good prognosis.
