  2. 41. The genetic architecture of sexual dimorphism

    Author : Robert Griffin; Urban Friberg; Alexei Maklakov; Jon Ågren; Russell Bonduriansky; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; evolution; intralocus sexual conflict; sex chromosomes; sexually antagonistic selection; sexual dimorphism;

    Abstract : Phenotypic differences between the sexes evolve largely because selection favours a different complement of traits in either sex. Theory suggests that, despite its frequency, sexual dimorphism should be generally constrained from evolving because the sexes share much of their genome. READ MORE

  4. 42. Epidemiology and clinical importance of GB virus C/hepatitis G virus

    Author : Robert Halasz; Karolinska Institutet; Karolinska Institutet; []
    Keywords : GBV-C; HGV; prevalence; transmission; children; fulminant hepatic failure; clinical importance;

    Abstract : GB virus C (GBV-C) or hepatitis G virus (HGV) is a recently discovered enveloped RNA virus belonging to the Flaviviridae family. GBV-C/HGV has been suggested to be a causative agent of non-A-non-E hepatitis. However, several contradictory observations cast doubts that it actually causes hepatitis. READ MORE

  6. 44. Activity concentrations of radionuclides in energy production from peat, wood chips and straw

    Author : Robert Hedvall; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radionuclides; peat; wood; chips; straw; bioenergy; biomass; district heating; emission; Cs; Physics; Chernobyl; Radioactivity; Fysik; Technological sciences; Teknik; Fysicumarkivet A:1997:Hedvall;

    Abstract : In this thesis quantitative analyses of radionuclide concentrations in bioenergy fuels such as peat, wood chips and straw are presented. For comparison a brief description is included of radionuclide concentrations and radiation doses from other sources of power and also from some industrial applications. READ MORE

  7. 45. Cell adhesion molecules during odontogenesis and tooth-related diseases

    Author : Robert Heymann; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cell adhesion molecules play essential roles in the development and disease of tooth and oral structures, as well as in the maintenance of adult tissue structure/function. It has been shown that different types of cell adhesion molecules (CAMs) play an important part in craniofacial development when ectomesenchymal cells migrate from the neural list to the primitive oral cavity, giving rise to the palatal processes and tooth germs.
