  1. 1. dNTPs  the alphabet of life

    University dissertation from Umeå : Umeå university

    Author : Dinesh Kumar; Umeå universitet.; [2010]
    Keywords : ribonucleotide reductase; dNTP pools; s-phase checkpoint; mutagenesis; medicinsk biokemi; Medical Biochemistry;

    Abstract : From microscopic bacteria to the giant whale, every single living organism on Earth uses the same language of life: DNA. Deoxyribonucleoside triphosphates––dNTPs (dATP, dTTP, dGTP, and dCTP)––are the building blocks of DNA and are therefore the “alphabet of life”. READ MORE

  2. 2. Interactions between Streptococcus pyogenes and the Human Immune System

    University dissertation from Lund University, Institute of Laboratory Medicine

    Author : Maria Weineisen; Lunds universitet.; Lund University.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; transplantation; Immunologi; serologi; virologi; mykologi; Immunology; mycology; Mikrobiologi; bakteriologi; virology; Biomedicinska vetenskaper; Neutrophils; Streptococcus pyogenes; Biomedical sciences; Phagocytosis; bacteriology; Microbiology; Integrins;

    Abstract : Streptococcus pyogenes is a common human pathogen causing mild infections such as tonsillitis and pharyngitis, but is also the cause of life-threatening conditions. To be able to infect the human host, S. pyogenes express different virulence factors. The surface-expressed M protein is a major virulence factor of S. READ MORE

  3. 3. The significance of sexuality and cyst formation in the life-cycles of four marine dinoflagellate species

    University dissertation from Lund University

    Author : Rosa Figueroa; Lunds universitet.; Lund University.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cyst; Hydrobiology; akvatisk ekologi; marine biology; aquatic ecology; limnology; sexuality.; meiosis; Lingulodinium polyedrum; life-cyle; limnologi; Marinbiologi; Gymnodinium nolleri; Gymnodinium catenatum; Alexandrium catenella; dinoflagellates;

    Abstract : Sexuality and cyst formation were studied in the marine dinoflagellate species Gymnodinium catenatum Graham, Gymnodinium nolleri Ellegaard ? Moestrup, Alexandrium catenella (Whedon et Kofoid) Balech, and Lingulodinium polyedrum (Stein) Dodge. The study included the morphological characterization of sexual stages and processes, the time and description of meiosis, the study of the length and regulation of the mandatory dormancy period of resting cysts, and the relationships among parental strains and cyst progeny at phenotypic and molecular levels.

  4. 4. Colonization, persistence and virulence factors in Escherichia coli strains in the human intestinal microflora

    University dissertation from Göteborg

    Author : Forough Nowrouzian; Göteborgs universitet.; Gothenburg University.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Escherichia coli; large intestine; infant; newborn; bacterial adhesins; hemolysins;

    Abstract : Escherichia coli is a member of the normal intestinal microflora of man and many animals. In this thesis, various aspects of the E. coli colonization pattern were studied, especially the role of so called virulence factors for persistence of E. coli in the gut microflora. READ MORE

  5. 5. Modeling Amyloid Disease in Drosophila melanogaster

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Ina Berg; Linköpings universitet.; Linköpings universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Amyloid diseases are caused by protein misfolding and aggregation. To date there are 27 known proteins causing amyloid disorders involving brain and peripheral protein deposition. The proteins involved in this mechanism do not share sequence homology, but the amyloid fibrils share biophysical properties and possibly a common pathogenic mechanism. READ MORE
