  3. 7. Viral parameters influencing clinical long-term non progression in HIV-1 infected subjects

    Författare :Ubaldo Visco Comandini; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :LTNP; HIV-1 DNA; HIV-1 RNA; quantification; spontaneous decrease; genetic heterogeneity; nef; LTR; CCR5 deletion;

    Sammanfattning : A very small portion of the HIV-1 infected population is constituted by individuals, called long- term non progressors (LTNP), in whom after even a decade or more, no visible deterioration of the immune system is recognized and the infection remains therefore asymptomatic. The reasons for such "natural" prolonged well-being can be attributed to both the virus and the infected host and their understanding is likely to give important information for the development of an effective HIV- vaccine and for immune reconstitution therapy.

  4. 8. Oscillator design in III-V technologies

    Författare :Szhau Lai; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MMIC; InGaP HBT; device model; mixer; Darlington pair; GaN HEMT; simulation; varactor; phase noise; CAD; switch mode.; VCO; Colpitts oscillator; low frequency noise;

    Sammanfattning : The thesis treats the design of low phase noise oscillators/VCOs in GaAs/InGaP HBT and GaN HEMT technologies. The covered topics are: active device modeling, noise characterization, passive structures, phase noise models, simulation/measurement tools, circuit topologies, and design techniques. LÄS MER

  5. 9. Selective Transformations of Allylic Compounds and Enol Derivatives : Synthesis of Fluorinated and Nitrogenated Scaffolds

    Författare :Víctor García-Vázquez; Belén Martín‐Matute; Mario Waser; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fluorinated compounds; Base catalysis; Ion-Pair; Isomerization; Pd catalysis; Method development; Hypervalent iodine III ; Organic Chemistry; organisk kemi;

    Sammanfattning : In this thesis, new synthetic methods to give access to molecules having fluorinated scaffolds and other polar functional groups have been developed. The methods give access to highly valuable organic compounds that may serve as building blocks in the synthesis of functionalized drug candidates. LÄS MER

  7. 10. Clinical and genetical aspects of Celiac Disease

    Författare :Audur Gudjonsdottir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; celiac disease; sib-pair; screening; genome-wide scan; linkage analysis; heritability; genotypes; DQ2-negative; phenotypes; autoimmune disease;

    Sammanfattning : Celiac disease (CD), or gluten-sensitive enteropathy, is one of the most common chronic diseases in childhood but is diagnosed in all ages. CD is a genetically driven immunological intolerance to dietary gluten. Th e treatment is a gluten-free diet. LÄS MER
