  1. 11. The cell cycle of the hyperthermophilic archaeal genus Sulfolobus

    Författare :Karin Hjort; Patrick Dennis; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; Cell cycle; Sulfolobus; Archaea; Origin; Replication; SIRV2; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; mikrobiologi; Microbiology;

    Sammanfattning : The third domain of life, Archaea is one of the three main evolutionary lineages together with the Bacteria and the Eukarya domains. The archaea are, despite their prokaryotic cell organisation, more closely related to eukaryotes than to bacteria in terms of the informational pathways (DNA replication, transcription and translation).

  3. 12. Studies on bacteria resistant and susceptible to humoral immunity in insects

    Författare :Inga Sidén; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Insects have developed several defense mechanisms against microorganismsi The injection of live bacteria into Lepidoptera pupae induces the synthesis of several bactericidal proteins, especially the cecropins and the attacins. Important properties of an insect pathogenic bacterium are invasiveness and resistance to immunity. LÄS MER

  4. 13. Mesenchymal Stem Cells in Tumor Growth Inhibition and Cartilage Differentiation

    Författare :Laura Varas; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper; Medicine human and vertebrates ; Medicin människa och djur ; mesenchymal stem cell; Biomedical sciences; tumor growth inhibition; FGF2; cartilage; integrin alpha11beta1; integrin alpha10beta1;

    Sammanfattning : The work presented in this thesis has been focused on mesenchymal stem cells (MSCs). In the two first studies, the effects of MSCs on tumor growth and development in vitro and in vivo was investigated. LÄS MER

  5. 14. Mechanisms and Biological Costs of Bacterial Resistance to Antimicrobial Peptides

    Författare :Hava Lofton Tomenius; Dan I Andersson; Ørjan Samuelsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; antibiotic resistance; fitness cost; Salmonella Typhimurium; Staphylococcus aureus; bile; serum; pH response; growth rate; mice; phoP; pmrB; waaY; LPS; LL-37; defensins; membrane potential; Mikrobiologi; Microbiology;

    Sammanfattning : The global increasing problem of antibiotic resistance necessarily drives the pursuit and discovery of new antimicrobial agents. Antimicrobial peptides (AMPs) initially seemed like promising new drug candidates. Already members of the innate immune system, it was assumed that they would be bioactive and non-toxic. LÄS MER

  7. 15. Synthesis and characterisation of Zintl hydrides

    Författare :Thomas Björling; Dag Noréus; Yvonne Andersson; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Zintl hydrides; BaGa2H2; SrAl2H2; SrAlSiH; BaAlSiH; CaAlSiH; SrGa2H2; Chemistry; Kemi; Structural Chemistry; strukturkemi;

    Sammanfattning : The synthesis, structural characterisation and the properties of the Zintl hydrides AeE2H2 and AeAlSiH (Ae = Ba, Ca, Sr; E = Al, Ga, In, Si, Zn) are reported. The first hydride in this class of compounds is SrAl2H2 which was discovered under an experiment by Gingl, who hydrogenated SrAl2 at various temperatures. LÄS MER
