  2. 16. Biological Markers of Fertility

    Author : Sarah Nordqvist; Helena Åkerud; Karin Kårehed; Agneta Skoog Svanberg; Anneli Stavreus-Evers; Geraldine Hartshorne; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; embryogenesis; female reproductive tract; fertility; fertilization; Histidine-rich glycoprotein; intron; in vitro fertilization; oocyte; ovarian response; pregnancy; single nucleotide polymorphism; Src homology 2 domain-containing adapter protein B;

    Abstract : Infertility affects 15 % of couples, which corresponds to 60 - 80 million worldwide. The microenvironments in which the oocyte, embryo and fetus mature are vital to the establishment and development of a healthy pregnancy. READ MORE

  4. 17. In vivo and in vitro evolution of molecular mechanisms - Importance in B cell development and phage display

    Author : Nina Nilsson; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; B cell development and phage display; transplantation; serology; Immunology; Immunologi; serologi; Biology; Biologi;

    Abstract : Bone marrow resident hematopoietic stem cells differentiate into all different types of lymphoid populations, there among mature naive B cells expressing IgM and IgD. During the maturation, the B cells are subjected to several steps of selection to ensure proper development of the antigen receptor. READ MORE

  5. 18. The birth of the hydrogenase : Studying the mechanism of [FeFe] hydrogenase maturation

    Author : Brigitta Németh; Gustav Berggren; Ann Magnuson; Mohamed Atta; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HydF; HydA; [FeFe] hydrogenase maturation; semi-synthetic enzymes; Biokemi; Biochemistry;

    Abstract : The [FeFe] hydrogenases are ancient metalloenzymes that catalyse the reversible interconversion between protons, electrons and molecular hydrogen. Despite the large structural variability within the [FeFe] hydrogenase family, the active site, the so called “H-cluster” is present in every representative.

  6. 19. Understanding Composition–Structure–Bioactivity Correlations in Bioactive Glasses

    Author : Yang Yu; Mattias Edén; Laurent Delevoye; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioactive glasses; Phosphosilicate glasses; Borophosphosilicate glasses; Solid-state NMR spectroscopy; Glass structure; Fourier-transform infrared spectroscopy; Hydroxyapatite; Amorphous calcium phosphate; Apatite formation; In vitro bioactivity testing; Physical Chemistry; fysikalisk kemi;

    Abstract : Bioactive glasses integrate with bone/tooth tissues by forming a layer of hydroxy-carbonate apatite (HCA), which mimics the composition of bone mineral. In the current thesis, we investigated composition–structure–bioactivity correlations of phosphosilicate and borophosphosilicate (BPS) glasses. READ MORE

  7. 20. Phenotype and function of CD25+ regulatory T cells in infants and adults

    Author : Hanna Grindebacke; Göteborgs universitet; []
    Keywords : Immunology; CD4 CD25 FOXP3 regulatory T cells; human; allergy; IL-10; Systemic immunotherapy; migration; homing receptors; maturation;

    Abstract : Active suppression by CD4+CD25+FOXP3+ regulatory T cells (Treg) is essential for the maintenance of peripheral tolerance to both self antigens and environmental antigens. Absence of these cells in human newborns leads to autoimmune and inflammatory disorders as well as allergic disease. READ MORE
