  1. 1. Repertoire diversity and maturation of HIV-1 vaccine-induced B cell responses

    Författare :Ganesh Eknath Phad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In the work presented in this thesis, I characterized B cell responses in rhesus macaques inoculated with HIV-1 envelope glycoprotein (Env)-based vaccines to define genetic and functional properties of the elicited antibodies for an improved understanding of Env immunogenicity. In Paper I, we investigated antibody heavy chain V gene segment expression in the overall B cell repertoire and in response to vaccination by using 2 approaches, 454-pyrosequencing and single-cell RT-PCR of bulk and sorted memory B cells, respectively.

  3. 2. HIV disease progression - Impact of HIV-1 intersubtype recombination and association with HIV-2 evolution

    Författare :Angelica Palm; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2) are both causative agents of AIDS, with similar pathogenic characteristics. However, the rate of disease progression is highly variable both within and between HIV-1 and HIV 2, but the mechanisms involved in modulating the rate of disease progression remain poorly understood.

  4. 3. Patch loading of stainless steel girders : experiments and finite element analyses

    Författare :Emma Unosson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : This thesis deals with the behaviour of stainless steel girders subjected to patch loading. The current loading situation arises for example at beam- column connections or at crane girders where the load is travelling along a girder. At bridge launching it is also important to consider patch loading. LÄS MER

  5. 4. The revolutionary partnership of computation and biology

    Författare :Salvador Daniel Rivas-Carrillo; Tanel Punga; Manfred Grabherr; Jan Komorowski; Mauno Vihinen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The organization of living beings is complex. Science uses modeling in order to gain a deeper understanding, and to be able to manipulate the processes of living organisms. To this purpose, I used and developed computational tools to investigate and model different relevant biological phenomena. LÄS MER

  7. 5. Studies on the barrier properties of exterior wood coatings

    Författare :Jan Ekstedt; KTH; []
    Nyckelord :Coatings; surfactants; water absorption value; EN 927; paint; additives; moisture dynamics; absorption; desorption; artificial weathering; artificial exposure; computerized tomography; MRI.;

    Sammanfattning : Coatings for exterior wood have two basic functions. One isto give an aesthetically acceptable surface appearance andcolour. The other is to provide protection against wooddegradation by microbiological or physical attack. LÄS MER
