  3. 7. Abdominal Aortic Aneurysm : Epidemiological and Health Economic Aspects

    Författare :Kevin Mani; Anders Wanhainen; Martin Björck; Jonas Lundkvist; Craig Kent; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Abdominal aortic aneurysm; cost; cost-effectiveness; endovascular aneurysm repair; screening; surgery; survival; Vascular surgery; Kärlkirurgi; Kirurgi; Surgery;

    Sammanfattning : Abdominal aortic aneurysm (AAA) is a common disease that is life threatening when rupture occurs. The aims of this thesis were to study (I) the long-term survival after AAA repair, (II) the cost of repair with open (OR) and endovascular (EVAR) technique, (III) the effect of different statistical methods on interpretation of cost data, (IV) the prevalence of the disease among patients with suspected arterial disease referred to the vascular laboratory, and (V) the cost-effectiveness of selective high-risk screening.

  4. 8. Palaeoenvironmental reconstructions from modern and ancient plant DNA

    Författare :Kevin Nota; Laura Parducci; Love Dalén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular palaeoecology; Ancient lake sediments; Post-glacial migration; Floral changes; Biology with specialization in Ecological Botany; Biologi med inriktning mot ekologisk botanik;

    Sammanfattning : Palaeoecological studies on lake sediments and peat archives have provided fundamental knowledge about past environments, nevertheless, a lot remains to be learned. In this thesis, I focussed on plant ancient DNA extracted from sedimentary archives (sedaDNA), in combination with DNA from living trees with the aims of: (1) investigating different extraction methods and levels of inhibition in sediments, (2) investigating postglacial recolonisation history of Norway spruce in Fennoscandia, (3) comparing different sequencing and bioinformatic approaches to investigate past flora changes using sedaDNA and investigating past flora change in contrasting environments (southern Italy versus southern Sweden), and (4) communicating my work more broadly using art.

  5. 9. The role of PDGFB in dermatofibrosarcoma protuberans and giant cell fibroblastoma

    Författare :Kevin P O'Brien; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dermatofibrosarcoma protuberans; giant cell fibroblastoma; translocation; FISH; translocation breakpoint; fusion gene; oncogene; Platelet derived growth factor B-chain; collagen type I alpha 1; tumor formation; autocrine stimulation;

    Sammanfattning : Dermatofibrosarcoma protuberans (DFSP) and giant cell fibroblastoma (GCF) are rare invasive tumors of the dermis. GCF is considered the juvenile form of DFSP. Both DFSP and GCF are characterized by the presence of chromosomal aberrations involving chromosomes 17 and 22. LÄS MER

  7. 10. Lignin- and PAN-based carbon fibres as negative electrodes for alkali-ion batteries

    Författare :Kevin Peuvot; Göran Lindbergh; Dan Zenkert; Enn Lust; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hard carbon; lithium-ion batteries; sodium-ion batteries; potassium-ion batteries; lignin-based carbon fibres; PAN-based carbon fibres; free-standing electrodes; Chemical Engineering; Kemiteknik;

    Sammanfattning : The development of sodium-ion batteries (SIBs) and potassium-ion batteries (KIBs) have accelerated since they can now reach similar gravimetric energy densities as lithium-ion batteries (LIBs) but with a lower environmental impact. Hard carbon is the most common negative electrode for SIBs and KIBs and can be made from renewable resources such as lignin. LÄS MER
