    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hyaluronan; Phospholipid; Lubricin; Cartilage Oligomeric Matrix Protein; COMP; Adsorption; Surface Force; Friction; Biolubrication; Boundary Lubrication; Load Bearing Capacity; Synergistic Effects; DLS; QCM-D; AFM.; Hyaluronan; Fosfolipid; Lubricin; Cartilage Oligomeric Matrix Protein; COMP; Adsorption; Ytkraft; Friktion; Biologisk smörjning; Gränsskiktssmörjning; Lastbärande förmåga; Synergieffekter; DLS; QCM-D; AFM.; Kemi; Chemistry;

    Abstract : The main objective of this thesis work was to gain understanding of the principles of biolubrication, focusing on synergistic effects between biolubricants. To this end surface force and friction measurements were carried out by means of Atomic Force Microscopy, using hydrophilic and hydrophobic model surfaces in salt solutions of high ionic strength (≈ 150 mM) in presence of different biolubricants.

    Abstract : In this thesis, porous graphitic carbon (PGC) has been used as packing material in packed capillary liquid chromatography. The unique chromatographic properties of PGC has been studied in some detail and applied to different analytical challenges using both electrospray ionization-mass spectrometry (ESI-MS) and ultra violet (UV) absorbance detection.

    Abstract :   Cisplatin (CisPt) is an important drug that is used against various cancers, including testicular, ovarian, lung, head, and neck cancer. However, its effects are limited by cellular resistance. READ MORE

  5. 5. Regulation of the multi-functional protein YscU in assembly of the Yersinia type III secretion injectisome

    University dissertation from Umeå : Umeå University

    Author : Ho Ngoc Hoang Oanh; Magnus Wolf-Watz; Anna Linusson Jonsson; Maria Sunnerhagen; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Type III secretion system T3SS ; injectisome; Yersinia pseudotuberculosis; inhibitors; Yops; YscU; YscP; YscI; disorder-to-order transition; nuclear magnetic resonance NMR ; circular dichroism CD ; isothermal titration calorimetry ITC ; biologisk kemi; biological chemistry;

    Abstract : Yersinia pseudotuberculosis is a Gram-negative zoonotic pathogenic bacterium causing gastroenteritis in human and animals. It shares a conserved virulence plasmid encoding for a needle-like secretion machinery, or type III secretion system, which can be found in other pathogenic Gram-negative bacteria. READ MORE
