  2. 16. Immune response during hepatitis B virus infection and reconstitution of HBV-specific immunity using T cells redirected against HBV

    Author : Sarene Koh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Hepatitis B is one of the most prevalent viral diseases worldwide and is a major public health concern, particularly in Asia. Of the 350 million people suffering from chronic hepatitis B virus (HBV) infection worldwide, approximately 75% are found in Asia. READ MORE

  4. 17. Hepatitis B virus replication and integration

    Author : Simon B. Larsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hepatitis B virus; replication; integration; HBV DNA; HBsAg;

    Abstract : Chronic infection with hepatitis B virus (HBV) affects 240 million people worldwide and may cause liver disease including hepatocellular carcinoma (HCC). Initially patients have high levels of HBV DNA in their blood, no liver disease and express the e antigen (HBeAg). READ MORE

  5. 18. Impaired response to HBV vaccination in HIV-1 infected children : immunopathological mechanisms

    Author : Yonas Bekele Feyissa; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : HBV vaccination prevents HBV infection and related liver cancer. Immunological dysfunctions of Tfh and B cells in HIV-1 infected individuals may affect the response to HBV vaccine. READ MORE

  6. 19. Symmetric varactor frequency multipliers

    Author : Mattias Ingvarson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sub-millimetre wave; heterostructure barrier varactor HBV ; symmetric varactor; frequency multiplier; millimetre wave; semiconductor diode;

    Abstract : This thesis describes heterostructure barrier varactor (HBV) frequency multipliers for millimetre and sub-millimetre wave applications.The basic principles of HBVs are explained. Starting from basic varactor theory, an equivalent circuit model for HBVs is presented. READ MORE

  7. 20. Planar Heterostructure Barrier Varactor Diodes for Millimetre Wave Applications

    Author : Jan Stake; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; millimetre- and sub-millimetre wave power source; III-V semiconductor; varactor diode; frequency multiplier; Heterostructure Barrier Varactor HBV ;

    Abstract : This thesis deals with fabrication, characterisation and modelling of the Heterostructure Barrier Varactor (HBV) diode and its use in frequency multiplier applications. Different aspects of material structures and frequency multipliers are described. READ MORE
