  1. 1. dNTPs  the alphabet of life

    University dissertation from Umeå : Umeå university

    Author : Dinesh Kumar; Andrei Chabes; Britt-Marie Sjöberg; [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; [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; [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. Microbial biofilms on peritoneal dialysis catheters

    University dissertation from Malmö University, Faculty of Odontology, Department of Oral Biology

    Author : Maria Pihl; [2011]

    Abstract : Då njurarna slutar fungera produceras ingen urin, och avfallsprodukterna stannar kvar i blodet. Detta tillstånd kallas uremi (”urin i blodet”) och leder till döden om det inte behandlas. Det finns två artificiella sätt att rena blodet på, hemodialys och peritonealdialys. READ MORE

  5. 5. 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
