  1. 1. Hepatitis B virus infection and genomic changes from a long-term perspective

    University dissertation from Jonas Bläckberg, Infektionskliniken, Universitetssjukhuset, 22185 Lund

    Author : Jonas Bläckberg; Lunds universitet.; Lund University.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; cor promoter; precore; occult infection; HBV; mutation;

    Abstract : Popular Abstract in Swedish Infektiös hepatit eller gulsot kan orsakas av flera olika sorters virus. De har alla det gemensamt att de orsakar en inflammation av levern. Namnet gulsot kommer av att när leverns funktion nedsätts så ansamlas ett färgämne i kroppen och ger ögonvitorna och huden en synlig gulgrön färg. READ MORE

  2. 2. Structure and Dynamics of the Hepatitis B Virus Encapsidation Signal Revealed by NMR Spectroscopy

    University dissertation from Umeå : Medicinsk biokemi och biofysik

    Author : Sara Flodell; Umeå universitet.; [2004]
    Keywords : HBV; RNA; isotope labelling; NMR; structure determination; medicinsk biokemi; Medical Biochemistry;

    Abstract : This thesis describes the study of the three-dimensional structure and dynamics of the hepatitis B virus (HBV) encapsidation signal, epsilon, by means of nuclear magnetic resonance (NMR) and mutational data. HBV replicates by reverse transcription of an RNA pregenome into the viral DNA genome, which becomes enclosed in viral particles (encapsidation). READ MORE

  3. 3. Genetic heterogeneity of hepatitis B and D viruses in chronic infection

    University dissertation from Yong Yuan Zhang, Dept. of Medical Microbiology, Section of Virology, University Hospital, MAS, 205 02 Malmo, SWEDEN

    Author : Yong Yuan Zhang; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteriology; Microbiology; phylogenetic analysis; mutant; mutation; genetic heterogeneity; HBV; HDV; hepatitis B; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : During the prolonged course of chronic viral infection there is a continuous reciprocal interaction between the host immune defence system and the viral immunogens, and viral genetic mutations capable of circumventing host immune defence could be selected for. Our observation of increasing prevalence of heterogeneity in the DNA sequence coding for the ‘a1 determinant of HBsAg in patients with presumed increasing length of chronic HBV infection is in agreement with the assumption of accumulation of presumed escape mutants.

  4. 4. Building a coherent hydro-climatic modelling framework for the data limited Kilombero Valley of Tanzania

    University dissertation from Stockholm : Stockholm University

    Author : Alexander Koutsouris; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Precipitation; Recession analysis; End - member mixing analysis; EMMA; GLUE; HBV; down scaling; Quantile mapping; CFSR; CMORPH; CRU; GPCC; ERA - i; MERRA; TRMM; UDEL; Satellite; Reanalysis; Kilombero; Tanzania; Eastern Africa; Africa; Physical Geography; naturgeografi;

    Abstract : This thesis explores key aspects for synthesizing data across spatiotemporal scales relevant for water resources management in an Eastern Africa context. Specifically, the potential of large scale global precipitation datasets (GPDs) in data limited regions to overcome spatial and temporal data gaps is considered. READ MORE

  5. 5. NMR studies of host-pathogen interactions

    University dissertation from Umeå

    Author : Katja Petzold; Umeå universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; regulatory RNA; HBV; H.pylori; phospholipids; ROESY; NATURAL SCIENCES Chemistry Molecular biophysics; NATURVETENSKAP Kemi Molekylär biofysik; biokemi; Biochemistry;

    Abstract : This thesis describes the use of Nuclear Magnetic Resonance (NMR) for characterizing two host-pathogen interactions: The behavior of a regulatory RNA of the Hepatitis B virus (HBV) and the attachment of Helicobacter pylori (H. pylori) to the gastric mucosa. READ MORE
