  1. 1. Costs, benefits and constraints in the evolution of avian reproductive tactics: a study on the blue tit

    Författare :Erik Svensson; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reproductive timing; selection analysis; natural selection; mate quality; nestlings; sex ratio; DNA-content; flow cytometry; ELISA; BMR; energetics; immunocompetence; immune system; sexual conflict; nestling mortality; thermoregulation; moult; reproductive costs; reproductive effort; Parus caeruleus; blue tit; birds; juvenile survival; laying date; food supply; Animal ecology; Djurekologi;

    Sammanfattning : In this study I have investigated the various factors influencing reproductive tactics among breeding blue tits (Parus caeruleus). The study was carried out in a nestbox-breeding population of marked individuals at the Revinge Area, outside Lund, southern Sweden. LÄS MER

  5. 4. 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

  7. 5. DNA content, proliferation markers and histopathology as prognostic factors in Astrocytic tumours

    Författare :Ludek Vavruch; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The DNA index and S-phase fractions obtained from freshly frozen and paraffin-embedded specimens of 49 primary intracranial tumors showed significant correlation. Very similar results were obtained when a subgroup of astrocytomas was analyzed. LÄS MER
