    Sammanfattning : Giardia intestinalis (syn. G. lamblia, G. duodenalis) is an intestinal protozoan parasite that causes diarrheal infections worldwide. LÄS MER

  3. 17. Ribosome and ribosomal RNA Structure : An experimental and computational analysis of expansion segments in eukaryotic ribosomal RNA

    Författare :Gunnar Alkemar; Odd Nygård; Anders Virtanen; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eukaryotes; expansion segment; ribosomes; rRNA; secondary structure; structure of rRNA.; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

    Sammanfattning : Ribosomes are large ribonucleoprotein complexes which incorporate amino acids into peptide chains during translational process in all types of living cells. The eukaryotic ribosome is larger compared to its prokaryotic counterpart. LÄS MER

  4. 18. Platelet-derived growth factor-induced signal transduction

    Författare :Sigrídur Valgeirsdóttir; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Cellbiologi; Cell biology; Cellbiologi; molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Platelet-derived growth factor (PDGF), a potent mitogen for mesenchymal cells, elicits its effects by binding to cell surface tyrosine kinase receptors, denoted α- and β-receptors. This thesis describes the mechanism of interaction between stimulated PDGF receptors and various intracellular molecules. LÄS MER

  5. 19. Studies of Giardia-host interactions: role of cysteine-rich surface proteins

    Författare :Dimitra Peirasmaki; Staffan Svärd; Steven Singer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Giardia; intestinal parasite; parasite infection; host-parasite interaction; virulence factors; HCMPs; cysteine-rich proteins; secretome; proteome;

    Sammanfattning : Giardia intestinalis is a eukaryotic parasite that colonizes the small intestine of humans and animals causing the diarrheal disease known as giardiasis. This parasite is not invasive and does not internalize into host cells but it rather attaches to the brush border surface of the small intestine disrupting the epithelial barrier. LÄS MER

  7. 20. QCM-D – with focus on biosensing in biomolecular and cellular systems

    Författare :Erik Nilebäck; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; QCM-D; biomolecular interactions; cell-surface interaction; glycosaminoglycans; viscoelasticity; cell morphology; Quartz crystal microbalance with dissipation monitoring; surface chemistry; protein conformation;

    Sammanfattning : The high degree of complexity in biological systems is being investigated in greater and greater detail by increasingly sophisticated sensing approaches. The quartz crystal microbalance with dissipation monitoring (QCM-D) technique stands out in this context, by probing the viscoelastic properties at interfaces. LÄS MER
