  1. 1. Data Analysis and Next Generation Sequencing : Applications in Microbiology

    Författare :Nicolas Innocenti; Erik Aurell; Mogens Jensen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; RNA-seq; tagRNA-seq; primary and processed RNA; Enterococcus faecalis; Complex transcription; Metagenomics; 5 tagRACE; minimal absent words; compressed sensing; metagenomics; bacterial community reconstruction; Biologisk fysik; Biological Physics;

    Sammanfattning : Next Generation Sequencing (NGS) is a new technology that has revolutionized the way we study living organisms. Where previously only a few genes could be studied at a time through targeted direct probing, NGS offers the possibility to perform measurements for a whole genome at once. LÄS MER

  3. 2. Chicken domestication : Effects of tameness on brain gene expression and DNA methylation

    Författare :Johan Bélteky; Per Jensen; Anna Kukekova; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Domestication greatly increases phenotypic variation in a short time span, with selection for a single phenotype and a plethora of associated phenotypic changes as an outcome of the process. The domestication process influences the underlying genomic architecture of a species, and the success and speed of the process is likely influenced by it. LÄS MER

  4. 3. Macroalgae in tropical seascapes : regulating factors and functions in the coastal ecosystem

    Författare :Gustaf Lilliesköld Sjöö; Max Troell; Nils Kautsky; Lena Kautsky; Alina Szmant; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Macroalgae; Coral reefs; Nutrients; Herbivory; Ecological functions; East Africa; Regulating factors; Anthropogenic influence; Seaweed farming; Bioindicator; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Although macroalgae usually are inconspicuous on pristine coral reefs, they often thrive on reefs that are subjected to various types of anthropogenic disturbance. This thesis consists of five papers and investigates how biomass and composition of macroalgal communities on coral reefs are affected by regulating factors, such as nutrient availability, herbivory, substrate availability and hydrodynamic forces.

  5. 4. Tissue Factor Biological Functions : Coagulation Activity in Microparticles and Signaling with Focus On Migration and Apoptosis

    Författare :Mikael Åberg; Agneta Siegbahn; Carl-Henrik Heldin; Teet Velling; Björn Dahlbäck; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue factor; Apoptosis; Migration; Chemotaxis; Simvastatin; Platelet Derived Growth Factor; Cell Signaling; Microparticles; Prostasomes; Trombosis; Coagulation; Prostate Cancer; Breast Cancer; Caspase-3; Caspase-8; NFkappaB; PAR2; Transactivation; Monocytes; Clinical chemistry; Klinisk kemi;

    Sammanfattning : Background: Tissue factor (TF) is a 47 kDa transmembrane glycoprotein known as the main initiator of blood coagulation. TF is over-expressed on many malignant cells and apart from increasing the risk of thrombosis, the presence of TF/FVIIa also promotes the progression of cancer and metastasis by intracellular signaling.

  7. 5. Exploring the Interplay of Lipids and Membrane Proteins

    Författare :Candan Ariöz; Åke Wieslander; Daniel O. Daley; Malcolm East; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane lipids; membrane proteins; anionic lipids; membrane remodeling; intracellular vesicles; model membrane systems; glycosyltransferase; Escherichia coli; lipid composition; fatty acid modification; membrane curvature; bacterial homeoviscous adaptation; Biochemistry; biokemi;

    Sammanfattning : The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models. LÄS MER
