  2. 1. Autonomous Åland : A hundred years of borderwork in the Baltic Sea

    Author : Ida Hughes Tidlund; Simon Ekström; Barbro Blehr; Thomas M. Wilson; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Åland; Finland; borders; borderwork; built place; practico-inert; hodological navigation; maritime; minority; territorial autonomy; Ethnology; etnologi;

    Abstract : This dissertation applies an ethnological and long-temporal view of borders. The region of Åland, being an autonomous and demilitarised island territory under Finnish sovereignty, serves as an illuminative case of the work that goes into keeping borders fixed for two reasons.

  4. 2. Studies on the functional interaction of translation initiation factor IF1 with ribosomal RNA

    Author : Jaroslav Belotserkovsky; Leif Isaksson; Diarmaid Hughes; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; ribosome; rRNA mutation; molekylärgenetik; Molecular Genetics;

    Abstract : Translation initiation factor IF1 is a small, essential and ubiquitous protein factor encoded by a single infA gene in bacteria. Although several important functions have been attributed to IF1, the precise reason for its indispensability is yet to be defined. READ MORE

  5. 3. Genetics and Growth Regulation in Salmonella enterica

    Author : Jessica M. Bergman; Diarmaid Hughes; Dan I. Andersson; Måns Ehrenberg; Stanley Maloy; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tufA; tufB; EF-Tu; ppGpp; Stringent response; RNase E; RNA turnover; Post-transcriptional regulation; rpoB; rpoS; Growth in stationary phase; Biology with specialization in Microbiology; Biologi med inriktning mot mikrobiologi; Mikrobiologi; Microbiology; Molekylär genetik; Molecular Genetics; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Abstract : Most free-living bacteria will encounter different environments and it is therefore critical to be able to rapidly adjust to new growth conditions in order to be competitively successful. Responding to changes requires efficient gene regulation in terms of transcription, RNA stability, translation and post-translational modifications. READ MORE

  6. 4. Meticulous control of the T3SS of Yersinia is essential for full virulence

    Author : Ann-Catrin Björnfot; Hans Wolf-Watz; Kelly T. Hughes; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Yersinia; type III secretion; YscU; substrate specificity switch; heat shock proteins; VagH; methyltransferase; virulence; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The type III secretion system (T3SS) of pathogenic Yersinia pseudotuberculosis is involved in virulence. The syringe-like secretion system spans both bacterial membranes and is responsible for the ability of Yersinia to transfer toxic proteins (Yop proteins) into the eukaryotic target cell. READ MORE

  7. 5. Biased Evolution : Causes and Consequences

    Author : Gerrit Brandis; Diarmaid Hughes; Erik Böttger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evolution; Codon usage bias; Post-transcriptional regulation; Recombination; Inversion; EF-Tu; Frameshift suppression; Antibiotic resistance; Rifampicin; Ciprofloxacin; Compensatory evolution; Drug efflux; RNA polymerase; DNA gyrase; Mikrobiologi; Microbiology;

    Abstract : In evolution alternative genetic trajectories can potentially lead to similar phenotypic outcomes. However, certain trajectories are preferred over others. These preferences bias the genomes of living organisms and the underlying processes can be observed in ongoing evolution. READ MORE
