  1. 16. Bowel irradiation: the effects on inflammation and matrix-metalloproteinases

    Författare :ANDREA POLISTENA; Kirurgi; []
    Nyckelord :Radiotherapy; Inflammation; Colorectal Cancer; MMP-7; Matrilysin; Bacteria;

    Sammanfattning : Background and aims: Radiotherapy is a valid treatment in cancer multimodal management but it is affected by severe systemic and local side effects. A murine small bowel model was used for the investigation of inflammatory features and apoptosis of local radiotherapy. LÄS MER

  3. 17. Electrochemical and mechanical thin film sensors

    Författare :Lars Henrik Skjolding; Fasta tillståndets fysik; []

    Sammanfattning : This thesis focuses on the study of thin-film sensor technologies, novel microfabrication technologies, and thin-film technology in general. The work discusses electrochemical sensors and mechanical sensor technologies as well as fabrication strategies for them. LÄS MER

  4. 18. Relation Between Drug Exposure and Selection of Antibiotic Resistant Bacteria

    Författare :Sara K. Olofsson; Otto Cars; Dan I. Andersson; Diarmaid Hughes; George G. Zhanel; Uppsala universitet; []
    Nyckelord :Microbiology; Pharmacokinetics; Pharmacodynamics; Antibiotic resistance; Selection; Transmission; Mathematical model; Escherichia coli; Mikrobiologi;

    Sammanfattning : The worldwide increase in antibiotic resistance is a concern for public health. When the appropriate antibiotic dosage is determined, the priorities are efficacy and toxicity. The aim of this thesis was to gain knowledge about the most efficient dosing regimens in order to minimize the emergence and selection of antibiotic-resistant mutants. LÄS MER

  5. 19. Abiotic stress and plant-microbe interactions in Norway spruce

    Författare :Julia Christa Haas; Vaughan Hurry; Nathaniel Street; Torgny Näsholm; Jennifer Baltzer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; boreal forest; cold; drought; bacteria; fungi; plant-microbe interactions; climate change;

    Sammanfattning : Norway spruce (Picea abies) is a dominant tree species in boreal forests with extensive ecological and economic value. Climate change is threatening these ecosystems, with rising temperatures impacting cold hardening and increasing drought stress in regions experiencing lower precipitation. LÄS MER

  7. 20. Energy Transfer Patterns in Photosynthetic Antenna System of Purple Bacteria
