  2. 16. Biogenesis, function and regulation of the type III secretion translocon of Yersinia pseudotuberculosis

    Author : Salah I. Farag; Matthew S Francis; Jörgen Johansson; Åke Forsberg; Luís Jaime Mota; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia pseudotuberculosis; type III secretion system; translocation; translocon; regulation; bacteria-eukaryotic cell contact; cytokine profiling;

    Abstract : Many Gram negative bacteria use type III secretion systems to cross-talk with eukaryotic cells. Type III secretion system assembly and function is tightly regulated. READ MORE

  4. 17. Biophysical studies of membrane interacting peptides derived from viral and Prion proteins

    Author : Kamila Oglęcka; Astrid Gräslund; Stephen White; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Prion peptides; Doppel peptide; Influenza fusion peptides; peptide-membrane interactions; translocation; linear dichroism; circular dichroism; Biophysics; Biofysik; Biophysics; biofysik;

    Abstract : This thesis focuses on peptides derived from the Prion, Doppel and Influenza haemagglutinin proteins in the context of bilayer interactions with model membranes and live cells. The studies involve spectroscopic techniques like fluorescence, fluorescence correlation spectroscopy (FCS), circular and linear dichroism (CD and LD), confocal fluorescence microscopy and NMR.

  5. 18. Type III secretion- the various functions of the translocon operon in bacterial pathogenesis

    Author : Jeanette E Bröms; Åke Forsberg; Michael Koomey; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Yersinia; Pseudomonas aeruginosa; type III secretion; chaperone; translocation; regulation; lcrGVHyopBD; pcrGVHpopBD; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : In order to establish colonisation of a human host, pathogenic Yersinia use a type III protein secretion system to directly intoxicate host immune cells. Activation of this system requires target cell contact and is a highly regulated process. READ MORE

  6. 19. Consumption patterns and excretion in aquatic food websenrichment

    Author : Anders Persson; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; trophic interactions; translocation; biomanipulation; enrichment; phosphorus; model; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Abstract : This thesis links biogeochemical cycling to classical ecology. Predictions derived from food chain theory, based on Lotka-Volterra type of interactions, were tested in aquatic environments with the main hypothesis that consumers affect lower levels of organization by both predation and excretion of limiting nutrients.

  7. 20. Molecular studies of genetic changes in myxoid and round cell liposarcoma

    Author : Sofia Järnum; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancerology; Cytologi; onkologi; cancer; Medicine human and vertebrates ; Medicin människa och djur ; oncology; Cytology; autocrine loop; RDA; persephin; RET; LEPREL1; translocation; fusion gene; liposarcoma; TLS; CHOP;

    Abstract : Chromosomal translocations commonly result in the production of fusion genes and the fusion genes are often tumor-type specific. In myxoid and round cell liposarcomas (MLS/RCLS), almost 95% of the cases carry a t(12;16)(q13;p11). In the remaining 5% of the MLS/RCLS tumors, another translocation and fusion gene can be found, i.e. READ MORE
