  1. 1. Electron Microscopy in Diagnostic Pathology with Reference to Mesenchymal Tumors

    Författare :Birgitta Carlén; Tumörmikromiljö; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; synovial sarcoma; Kaposi´s sarcoma; epithelioid sarcoma; parachordoma; alveolar soft part sarcoma; small cell malignant tumors of childhood and adolescence; cultured cells; surgical specimens; Transmission electron microscopy; fine needle aspiration; General pathology; pathological anatomy; Patologi allmän ; patologisk anatomi;

    Sammanfattning : The experience acquired over a period of 15 years of diagnostic electron microscopy of fine needle aspirates and surgical specimens constitutes the base for this thesis. Some of the tumors analyzed represent rare soft tissue tumors, and consequently not very often ultrastructurally described. LÄS MER

  5. 4. Regulators of angiogenesis in diabetes and tumors

    Författare :Sergiu-Bogdan Catrina; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Diabetes; HIF; hypoxia; tumors; growth factors; wound healing;

    Sammanfattning : Angiogenesis is tightly regulated in order to provide adequate supply of nutrients and oxygen for normal cellular function. Tissue oxygenation represents a balance between the requirement for oxygen to maintain the cellular energy level and the potential risk of cellular oxidative damage. LÄS MER
