  1. 1. Geographic and genetic diversity of hepatitis B

    Författare :Erik Alestig; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hepatitis B virus; genotype; phylogeny; molecular epidemiology; sequence analysis; mutation;

    Sammanfattning : Hepatitis B Virus (HBV) infection is a global health problem and may lead to chronic hepatitis, liver cirrhosis and hepatocellular cancer. The ability of HBV to adapt to the host environment by genetic variation has lead to the evolution of 8 established (A-H) and 2 putative genotypes (I-J), each corresponding to a rather well-defined geographical distribution.

    Sammanfattning : Cervical cancer (CC) is caused by a persistent infection of certain types of the human papillomavirus (HPV). Even though great progress has been made in strategies for prevention, and treatment of CC, there is still a need for improved methods in screening and management of women diagnosed with CC. LÄS MER

  3. 3. Clinical expressions of juvenile hereditary retinal degenerations and macular dystrophies: Electrophysiological and genetic studies

    Sammanfattning : Hereditary retinal degenerations are the most frequent reason for severe visual handicap among young people in Scandinavia today. In the six papers included in this thesis the phenotypic expressions, with emphasis on the electrophysiological findings, of five different juvenile hereditary retinal degenerations are described.
