    Sammanfattning : In this thesis I used allozymes and PCR-RFLP analysis of chloroplast DNA (cpDNA) to investigate geographic differentiation within the widespread Silene dioica (L.) Clairv. (Caryophyllaceae) and the narrowly-distributed S. hifacensis Rouy ex Willk. LÄS MER

  3. 22. The Adenovirus L4-33K Protein : A Key Regulator of Virus-specific Alternative Splicing

    Författare :Heidi Törmänen Persson; Göran Akusjärvi; Stefan Schwartz; Marie Öhman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; L4-33K; adenovirus; splicing; phosphorylation; localization; replication centers; L4-22K; MLTU; DNA-PK; DNA-dependent protein kinase; PKA; cAMP-dependent protein kinase; transcription sites; SR protein; Medical Virology; Medicinsk virologi;

    Sammanfattning : Adenoviruses have been extensively studied in the field of gene regulation, since their genes are subjected to a tightly controlled temporal expression during the virus lifetime. The early-to-late shift in adenoviral gene expression distinguishes two completely different programs in gene expression. LÄS MER

  4. 23. Statistical assessment of somatic mutations and genomic variability using DNA sequence data

    Författare :Anna Rehammar; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA sequence data; exome sequencing; calling of somatic mutations; metagenomics; hierarchical Bayesian model; genomic variability; calling of somatic mutations;

    Sammanfattning : The development of new DNA sequencing techniques have made it possible to generate high-resolution genomic data at an unprecedented pace. However, the high dimensionality in combination with the substantial levels of technical errors and biological variability make the analysis challenging. LÄS MER

  5. 24. Immune cells in human pharyngeal and palatine tonsils and in the uvula : tissue distribution, cellular composition and functional properties

    Författare :Katarina Olofsson; Marie-Louise Hammarström; Sten Hellström; Britta Rynnel-Dagöö; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The adenoid (pharyngeal tonsil), the palatine tonsils and the uvula are strategically located at the entrance of the upper airodigestive tract. By virtue of their location they are incessantly exposed to inhaled and ingested antigens. LÄS MER

  7. 25. Phylogeography and mitochondrial DNA diversity in arctic lemmings

    Författare :Vadim B. Fedorov; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Genetik; Clinical genetics; Klinisk genetik; Genetics; genetik;

    Sammanfattning : The aim of this thesis is to evaluate the effects of Quaternary environmental fluctuations on the present patterns of mitochondrial DNA variation in the wood lemming, Myopus schisticolor, and the two genera of Arctic lemmings: collared lemmings, Dicrostonyx, and true lemmings, Lemmus.The phylogeographic pattern and the limited mtDNA diversity in the Scandinavian populations of the wood lemming reflect recent colonization by a limited number of founders during the Holocene boreal forest expansion.
