  1. 21. Deg/HtrA proteases of the cyanobacterium Synechocystis sp. PCC 6803 : from biochemical characterization to their physiological functions

    Författare :Xuân Tâm Lâm; Christiane Funk; Jörg Nickelsen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deg; HtrA; protease; chaperone; Synechocystis sp. PCC 6903; biochemical characterization; physiological function; proteomics; structure;

    Sammanfattning : The family of Deg/HtrA proteases is present in a wide range of organisms from bacteria, archaea to eukaryota. These ATP-independent serine endopeptidases play key roles in the cellular protein quality control. The cyanobacterium Synechocystis sp. LÄS MER

  3. 22. Ethanol from lignocellulose : physiological effects of inhibitors and fermentation strategies

    Författare :Mohammad J Taherzadeh; Chalmers Univ of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acetic acid; Agents; Cellulose; Enzyme inhibition; Feedback control; Fermentation; Hydrolysis; Metabolites; pH; Physiology; Wood; Yeast; Dilute acid hydrolyzate; Inhibitors; Lignocellulose; Physiological effects; Saccharomyces cerevisiae; Ethanol;

    Sammanfattning : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). LÄS MER

  4. 23. Lung Transplantation: Clinical and experimental studies

    Författare :Leif Eriksson; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiratory system; Follow up Studies; Vascular Resistance; Intensive Care; Induced; Hypothermia; Swine; Extracorporeal Circulation; Lung Transplantation; Organ Preservation; Andningsorganen; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : During the past 15 years lung transplantation has been established as a therapeutic option for patients with end-stage pulmonary disease. The results have improved over time and some transplantation centers now show 1-year survival rates above 80%. LÄS MER

  5. 24. Structural Studies of Proteins involved in Nucleotide Metabolism : Studies of a ribonucleotide reductase from A. aeolicus and NUDT15

    Författare :Daniel Rehling; Pål Stenmark; Gisela Brändén; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray crystallography; ribonucleotide reductase; NUDT15; Biochemistry; biokemi;

    Sammanfattning : This thesis is separated into two parts. The first part concerns ribonucleotide reductase from Aquifex aeolicus. A. aeolicus is a hyperthermophilic bacterium that thrives at extremely high temperatures of 80-95 °C. LÄS MER

  7. 25. Physiological Studies of Native and Stem Cell-Derived Islets

    Författare :Daniel Norman; Per-Ola Carlsson; Daniel Espes; Helge Ræder; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Irisin; CART; Islet blood flow; Islets of Langerhans; Stem cell-derived islets; Fysiologi; Physiology; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : In type 1 and type 2 diabetes, the β-cells of the islets of Langerhans are either destroyed by the immune system or stressed due to peripheral insulin resistance. To improve the life of patients with these diseases, new treatments are needed. LÄS MER
