  1. 16. High-molecular-weight insulin-like growth factor 2 : immunohistochemical, ultrastructural and biochemical findings in insulin cells under normal, diabetic, and neoplastic conditions, and its role in non-islet cell tumour hypoglycaemia

    Författare :Anders Höög; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Insulin-like growth factor-2; IGF-2; islets of Langerhans; B-granules; Diabetes Mellitus type 2; insulinoma; Goto-Kakizaki rat; haemangiopericytoma; ultrastructural immunohistochemistry; gene expression.;

    Sammanfattning : IGF-2 immunoreactive (IR) cells were identified in the normal adult pancreas of man and rat and occurred exclusively in insulin-producing cells. When frozen human pancreatic tissue was extracted and gel-size-separated, a high-molecular-weight (HMW) IGF-2 peptide could be identified. LÄS MER

  3. 17. The micrometeorite flux to Earth through the Phanerozoic Eon : Reconstructed using sediment-dispersed extraterrestrial spinels

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chromite; chrome spinel; micrometeorites; Phanerozoic; asteroid breakup; ordinary chondrites; 3He anomalies; lunar impacts; ice age; impact craters; zircons;

    Sammanfattning : The purpose of this thesis is to add an astronomical component to the history and evolution of Earth by reconstructing the micrometeorite flux to Earth at different time intervals during the Phanerozoic Eon, using sediment-dispersed extraterrestrial spinel group minerals as a proxy. Chromite and chrome spinel are common refractory members of the spinel group, occurring in both extraterrestrial and terrestrial rocks. LÄS MER

  4. 18. Extensive tooth wear in adults : classification and prosthetic treatment

    Författare :Wedad Hammoudi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Tooth wear (TW) is an insidious and cumulative mul- tifactorial process that may comprise erosion, abrasion or attrition, and combinations thereof. These different processes are of chemical or physical origin and not microbiological. LÄS MER
