    Abstract : Coral reefs belong to the most diverse and the most threatened ecosystems on earth. Anthropogenic stressors and climate change have led to mortalities at levels unprecedented in modern times. The aims of this thesis are to investigate aspects of the corals’ ability to reproduce, disperse, adapt and survive. READ MORE

  3. 3. Caenorhabditis elegans as a model to elucidate host-pathogen interactions for human bacterial pathogens

    University dissertation from Stockholm : Karolinska Institutet, Dept of Microbiology, Tumor and Cell Biology

    Author : Xiao Hui Sem; Karolinska Institutet.; Karolinska Institutet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The soil nematode Caenorhabditis elegans is a popular host utilized to model bacterial virulence and microbial pathogenesis in vivo. This thesis explores the use of C. elegans for the study of host-pathogen interactions for two Gram-negative bacteria, Burkholderia thailandensis and Salmonella enterica. READ MORE

  4. 4. Oxidoreductases and RNA Degradosome Controlling Virulence-Associated Traits of Salmonella enterica serovar Typhimurium

    University dissertation from Stockholm : Karolinska Institutet, Dept of Microbiology, Tumor and Cell Biology

    Author : Naeem Anwar; Karolinska Institutet.; Karolinska Institutet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The oxidative stress response is a fundamental and primitive mode of innate immune defense in nearly all forms of life. The host oxidative stress response becomes truly important and effective especially against intracellular pathogens such as Salmonella. Pathogens have evolved diverse mechanisms to withstand the oxidative responses. READ MORE

  5. 5. Structural Studies of Polyamine Biosynthesis Enzymes: Potential Targets for Drugs against Tropical Parasites

    University dissertation from Department of Molecular Biophysics, Lund University

    Author : Veronica Tamu Dufe; Lunds universitet.; Lund University.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; inhibitors; protein crystallography; Molecular biophysics; Molekylär biofysik; tropical parasites; polyamine biosynthesis enzymes;

    Abstract : Two enzymes involved in the biosynthesis of polyamines, ornithine decarboxylase (ODC, from human and Leishmania donovani) and spermidine synthase (SPDS, from Plasmodium falciparum and Caenorhabditis elegans) were studied using biochemical methods, homology modelling and X-ray crystallography. ODC catalyses the first and committed step in polyamine biosynthesis, the decarboxylation of ornithine to putrescine. READ MORE
