  1. 1. The Cyanobacterial Uptake Hydrogenase : Regulation, Maturation and Function

    Författare :Marie Holmqvist; Peter Lindblad; Karin Stensjö; Kornél Kovács; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biohydrogen; CalA; Cyanobacteria; Hydrogenase; Maturation; Nostoc punctiforme ATCC 29133; Nostoc sp. PCC 7120; Transcriptional regulation; Molecular biology; Molekylärbiologi; Molecular biology; Molekylärbiologi; Chemistry with specialization in Microbial Chemistry; Kemi med inriktning mot mikrobiell kemi;

    Sammanfattning : With accellerating global warming and pollution problems a change of energy regime is necessary. Solar energy offers a clean and unlimited energy source of enormous potential. Due to it’s intermittenet nature solar energy must be stored - ideally in the chemical bond of a carrier molecule. LÄS MER

  3. 2. Cyanobacterial Hydrogen Metabolism : Regulation and Maturation of Hydrogenases

    Författare :Ellenor Devine; Peter Lindblad; Karin Stensjö; Laurent Cournac; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; hydrogenase; hydrogenase specific protease; maturation; regulation; transcriptional studies; hupW; hoxW; hyp; NtcA; CalA; Biology; Biologi; Molecular biology; Molekylärbiologi; Microbiology; Mikrobiologi; Chemistry with specialization in Microbial Chemistry; Kemi med inriktning mot mikrobiell kemi;

    Sammanfattning : In times with elevated CO2 levels and global warming there is a need of finding alternatives to carbon based energy carriers. One such environmental friendly solution could be H2 produced by living organisms. LÄS MER

  4. 3. Maturation and Regulation of Cyanobacterial Hydrogenases

    Författare :Åsa Agervald; Peter Lindblad; Karin Stensjö; Ann Magnuson; Poul Erik Jensen; Uppsala universitet; []
    Nyckelord :Biohydrogen; Cyanobacteria; Nostoc sp. PCC 7120; Nostoc punctiforme PCC 73102; Hydrogenase; Maturation; Transcriptional regulation; CyAbrB; CalA; FeSOD;

    Sammanfattning : Accelerated global warming plus an increasing need for energy is an equation not easily solved, thus new forms of sustainable energy production are urgently requested. In this context hydrogen production based on a cyanobacterial system offers an environmentally friendly alternative for energy capture and conversion. LÄS MER

  5. 4. Mechanisms of dendritic cell maturation induced by intracellular bacteria infection

    Författare :Miguel A. Tam; Göteborgs universitet; []
    Nyckelord :Listeria; Salmonella; dendritic cells; maturation; MyD88; IFN-? ?;

    Sammanfattning : Dendritic cells (DCs) are essential for the development of an immune response against pathogens such as Listeria monocytogenes and Salmonella typhimurium. This is mostly because of their unique capacity to stimulate naïve T cells. LÄS MER

  7. 5. Maturation-dependent normal and injury-induced changes in rabbit knee articular cartilage

    Författare :Xiaochun Wei; Leif Ryd; Linköpings universitet; []
    Nyckelord :rabbit; development; maturation; knee joint; articular cartilage; osteochondral defect; cartilage repair; joint fluid; subchondral bone volume fraction; proteoglycan fragment; transforming growth factor-ß; biomechanics; indentation; histology; hlstomorphometry; MEDICINE; MEDICIN;

    Sammanfattning : Cartilage injuries are common in sports, and may on the long term develop to osteoarthritis. Prosthetic joint replacement is not satisfactory for young active individuals with extended cartilage injuries in large weight-bearing joints. In these cases, a treatment is needed which reestablishes normal joint surfaces by biologic means. LÄS MER
