  1. 16. Of spiders, bugs, and men : Structural and functional studies of proteins involved in assembly

    Författare :Wangshu Jiang; Stefan D Knight; Steve J. Matthews; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein assembly; sulfate transporter; crystallography; Proteus mirabilis; fimbriae; adhesin; urinary tract infection; biofilm; spider silk; asymmetric dimer; Bri2; BRICHOS; molecular chaperone; Alzheimer s disease; amyloid; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Sammanfattning : Protein assembly enables complex machineries while being economical with genetic information. However, protein assembly also constitutes a potential threat to the host, and needs to be carefully regulated.Sulfate is a common source of sulfur for cysteine synthesis in bacteria. LÄS MER

    Sammanfattning : The organisation of fluids in small compartments is ubiquitous in nature, such as in the cellular composition of all life. This work explores several engineering avenues where microscale fluid compartmentalization can bring novel material properties or novel functionality in life sciences or medicine. LÄS MER

  4. 18. Calcium Phosphate Based Biomaterials for Bone Augmentation

    Författare :Jun Luo; Cecilia Persson; Håkan Engqvist; Marc Bohner; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone substitute materials; calcium phosphate cements; apatite; brushite; monetite; setting mechanism; premixed; fibre reinforcement; composite; silk fibroin; mechanical properties; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Basic (apatite-based) calcium phosphate cements (CPCs), and acidic (brushite and monetite-based) CPCs are used as bone replacement materials because of their bioactivity, mouldability and ability to harden in place. However, their application is limited by their inherent brittleness and difficulties related to their handling. LÄS MER

  5. 19. Engineering of Antibacterial Phage-Derived Proteins

    Författare :Fredrik Seijsing; Anders Nilsson; Yves Briers; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein engineering; endolysin; IgG; linker protein; chimeric protein; artificial opsonin; spider silk; antibacterial surface; bacteriophage; structure prediction; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The increasing threat of antibiotic resistance calls for the development of new treatment methods. Bacteriophages are interesting candidates since they can lyse bacteria with great efficiency. Bacteriophages produce enzymes called endolysins which break down the peptidoglycan in the cell wall at the end of the infection cycle. LÄS MER

    Sammanfattning : Using textiles as clues, it is shown that, like in the rest of Scandinavia, there is a legible societal shift in favour of a new Christian organization as early as around year 1000 even in the central parts of what is now Sweden, including the, according to Adam of Bremen, “pagan” Mälar valley. During a period of at least a hundred and fifty years, the Mälar valley with Birka in the centre had enjoyed eastern trade, which is reflected in the rich finds of oriental textile fragments in the Birka graves.
