  1. 1. Uropathogenic Esherichia coli, multidrug-resistance and induction of host defense mechanisms

    Författare :Isak Demirel; Katarina Persson; Robert Kruse; Mirjana Poljakovic; Gabriela Godaly; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urinary tract infection; uropathogenic Escherichia coli; suppressor of cytokine signalling 3; nitric oxide; cytokines; extended-spectrum beta-lactamases; filamentation; IL-6; Biomedicin; Biomedicine;

    Sammanfattning : Uropathogenic Escherichia coli (UPEC) is the primary cause of urinary tract infection (UTI), which is one of the most common infections in humans. UPEC strains have acquired successful strategies to subvert the host defense and antibiotics to persist in the urinary tract. LÄS MER

  3. 2. Potent inhibitors of uropathogenic E. coli papG adhesins; Synthesis, conformational studies and biological evaluation of galabiose derivatives and synthesis of glycosphingolipid analogues

    Författare :Jörgen Ohlsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Glycosphingolipid analogue; PapG adhesin; Esherichia coli; Galabiose analogues; Inhibitors; Glycoconjugates;

    Sammanfattning : The importance of carbohydrates in biological systems has become evident during the last fifty years. It is well known that pathogenic bacteria and viruses attach to glycoconjugates present at mammalian cell surfaces, and that this attachment is a prerequisite for the later stages of infection.

  4. 3. Molecular and Metabolic Aspects of Plant and Bacterial Salt Tolerance

    Författare :Peter Olsson; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Bioteknik; metabolism; gamma-aminobutyric acid; Nicotiana tabacum; salinity; hypoxia; heamoglobin; microarray; glycine betaine; NaCl; GABA; Vitreoscilla; calmodulin; Esherichia coli; tobacco; Biokemi; Metabolism; Biochemistry; Arabidopsis;

    Sammanfattning : Salt stress is one of the historically as well as potentially largest agriculture problem humans have faced. Researchers have investigated and tried to solve this problem for a long time. Over 20 reviews have been written on this topic the last five years. LÄS MER

  5. 4. Large-scale Bioreactor Phenomena and Characteristics; Effects on E.coli fed batch fermentations on 30m3 scale

    Författare :Gustav Silfversparre; KTH; []
    Nyckelord :Large-scale; E.coli; fed batch; concentration gradients; mixing;

    Sammanfattning : Due to economical and practical limitations the fluiddynamics and mass transport properties are less optimal inlarge-scale bioreactors compared to lab-scale bioreactors. Incombination with the microbial reaction rates this creates amuch more dynamic environment for cells cultivated inlarge-scale bioreactors compared to lab-scale bioreactors. LÄS MER

  7. 5. Immunological tolerance to antigens in the intestine

    Författare :Malin Karlsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rat; oral tolerance; serum factor; normal gut flora; exosomes;

    Sammanfattning : The major part of the immune system is found in the epithelium and lamina propria of the gut. The distribution of the leukocytes is structured probably because the immune system has to distinguish between harmful microorganisms, food antigens and the normal gut flora. LÄS MER
