  1. 1. Oxidative damage and the DNA glycosylase MutYH

    Author : Kristina Jansson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oxidative damage; 8-oxo-7; 8-dihydro-2′-deoxyguanosine; Base excision repair; DNA glycosylase; Mismatch repair; DNA damage checkpoint; 9-1-1 complex; Glutathione-S-transferases; Colon cancer.;

    Abstract : The DNA glycosylase MutYH is highly conserved throughout evolution, and homologs are found in most eukaryotes and prokaryotes examined. MutYH functions as a base excision repair DNA glycosylase that excises adenines misincorporated opposite 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxodG), one of the most stable products of oxidative DNA damage.

  2. 2. Complex methods of inquiry: structuring uncertainty

    Author : PETER BEDNAR; Institutionen för informatik; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; information system; Contextual Analysis; Contextual Dependencies; Systems Approaches; Systems Thinking; Organizational change; Complex adaptive systems; Uncertainty management; Organizational Emergence; Change Management; Organizational Learning; Human Activity Systems;

    Abstract : Organizational problem spaces can be viewed as complex, uncertain and ambiguous. They can also be understood as open problem spaces. As such, any engagement with them, and any effort to intervene in order to pursue desirable change, cannot be assumed to be just a matter of ‘complicatedness’. READ MORE

  3. 3. DNA checkpoint override and redox signaling in Schizosaccharomyces pombe

    Author : Johanna J Sjölander; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Caffeine; Cell cycle; Checkpoint; Cdc25; Wee1; TORC1; FHIT; Proliferation; Aph1; Redox; Hypoxia; H2O2; Cysteine; Thiol; Allosteric; MAPK; Sty1; MAPKK; Wis1;

    Abstract : This thesis covers intracellular stress signaling through genotoxic stress, overriding of checkpoint control, as well as cellular redox status in hypoxic and oxidative stress Papers I and II: Caffeine has been shown to override cell cycle checkpoints in humans as well as in the fission yeast Schizosaccharomyces pombe. Understanding of the mechanism may aid in the development of compounds with similar overriding mechanisms for sensitization in cancer therapy. READ MORE

  4. 4. Experimental studies on xenograft rejection

    Author : Guosheng Wu; Karolinska Institutet; Karolinska Institutet; []

    Abstract : The use of animal organs and tissues may provide a solution to the severe and worsening shortage of human grafts. The aims of the present experimental studies were to provide a better understanding of the rejection mechanisms and give new clues for prevention of xenorejection, thereby hopefully contributing to the development of clinical xenotransplantation.

  5. 5. The Hepatobiliary Transport of Rosuvastatin In Vivo

    Author : Ebba Bergman; Hans Lennernäs; Ulf Bondesson; Jack Cook; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rosuvastatin; Biliary excretion; Transport inhibition; Pharmacokinetics; Drug-drug interactions; Hepatobiliary transport; Organic anion transporting polypeptide; OATP; Statins; Gemfibrozil; Cyclosporine; Imatinib; Rifampicin; Canalicular transport; Sinusoidal transport; Hepatic uptake; Hepatic extraction; Biopharmacy; Biofarmaci; Biopharmaceutics; biofarmaci;

    Abstract : In vivo studies of hepatobiliary disposition are challenging. The hepatobiliary system is complex, as its physiological localization, complex cellular structure with numerous transporters and enzymes, and the interindividual variability in protein expression and biliary flow will all affect the in vivo disposition of a drug under investigation.
