  1. 26. Radiobiological studies with low energy ionizing radiation - dosimetric aspects

    Författare :Gustav Grafström; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low energy; Radiobiology; dosimetry; cell model; Radiofarmaceutisk teknik; Radiopharmaceutical technology; radiobiologi; Nukleärmedicin; radiobiology; Nuclear medicine; animal model;

    Sammanfattning : Background: During the last 20 years both in vitro and in vivo models have been developed for studies of the cell killing characteristics of low energy electrons, e.g. Auger electrons. This thesis deals with radiobiological effects of radiation from indium isotopes in V79 cells in vitro (Paper I-III) and the rat testis in vivo (Paper IVV). LÄS MER

  3. 27. The Testatin/Cres subgroup of family 2 cystatins in sexual development

    Författare :Jessica Frygelius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The genetic sex in mammals is established at fertilization, where an XX chromosome complement will lead to female development and an XY genotype will result in male development. Thereafter, sex determination is initiated with expression of the Y-linked factor Sry in XY gonads, leading to testis formation, while in the absence of Sry expression an ovary is formed. LÄS MER

  4. 28. The impression technique for assessment of tissue oedema : instrumentation, evaluation and applications

    Författare :Olof Lindahl; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICINE; MEDICIN; Medical Engineering for Healthcare;

    Sammanfattning : An instrument for clinical noninvasive assessment of tissue oedema based on an impression method was developed. The method measures and evaluates the decaying force, due to translocation of tissue fluid, during mechanical compression of any site of tissue. We applied the impression method on physical models, animal models, and patients. LÄS MER

  5. 29. Male reproductive health in environmental research : aspects of histological evaluation of testicular tissue

    Författare :Ellinor Spörndly-Nees; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : There is increasing concern that chemicals in the environment are causing male reproductive disorders in animals and humans. This thesis investigated different aspects of histological evaluation of testes, as a tool to measure effects of environmental chemicals on male reproductive health in wild and laboratory animals.

  7. 30. Cell transplantation with human mesenchymal or embryonic stem cells to the heart : experimental, molecular, immunological and echocardiographic studies

    Författare :Karl-Henrik Grinnemo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Human mesenchymal stem cells; human embryonic stem cells; human cardiomyocyte; Islet-1; Nkx2.5; stem cell; xenotransplantation; rejection; FoxP3 T-cells; tolerance; CTLA4Ig; anti- CD40L; LFA-1;

    Sammanfattning : Background: Human mesenchymal stem cells (hMSC), human embryonic stem cells (HESC) and human fetal cardiomyocyte progenitor cells (HFCP) all represent possible candidate cells for regeneration of damaged myocardium. Although they represent cell types with many positive attributes, their capacity to engraft, to differentiate into mature cardiomyocytes, to improve myocardial function and their immunological properties are the focus of these studies.
