  1. 1. Marsupial Mitogenomics

    University dissertation from Department of Cell and Organism Biology, Lund University

    Author : Maria Nilsson; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetics; Biologi; Biology; divergence times; K T-boundary; phylogenetic reconstruction; Ameridelphia; Australidelphia; Notoryctes; Dromiciops; Marsupialia; mitochondrial genomes; cytogenetics; Genetik; cytogenetik;

    Abstract : The relationships of the mammalian infraclass Marsupialia have been investigated by phylogenetic analysis using completely sequenced mitochondrial genomes. The organisation and structure of the marsupial mitochondrial genomes deviates from the general mammalian structure. READ MORE

  2. 2. High-Resolution Measurement of the 4He(g,n) Reaction in the Giant Resonance Region

    University dissertation from Department of Physics, Lund University

    Author : Björn Nilsson; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tagged photons; photonuclear reactions; liquid helium; neutron detectors; liquid scintillators; giant resonances; angular distributions; differential cross sections; total cross sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:2003:Nilsson;

    Abstract : A comprehensive near-threshold 4He(g,n) absolute cross section measurement has been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 20 < Eg < 45 MeV tagged photons (covering the Giant Dipole Resonance energy region) were directed towards a liquid 4He target, and knocked-out neutrons were detected in a pair of 60 cm x 60 cm vetoed NE213A liquid scintillator arrays.

  3. 3. The Immune System in the Oldest-Old Clinical and Immunological Studies in the NONA Immune Cohort

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Bengt-Olof Nilsson; Jan Ernerudh; Anders Wikby; Sture Löfgren; Karlis Pauksens; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Elderly; selection; health status; lymphocyte subsets; CD8; CMV; cytomegalovirus; immune risk; immune risk phenotype; IRP; T-cells; interleukin 6; IL-6; survival; mortality; antinuclear antibodies; ANA; ageing; immunosenescence; MEDICINE; MEDICIN;

    Abstract : The oldest-old (people aged 80 or older) constituted 5 % of the population in Sweden in 2000, an increase from 1.5 % fifty years earlier. The immune system undergoes dramatic changes at high age, sometimes referred to as “immunosenescence”. READ MORE

  4. 4. On the immunopathogenesis of HIV infection

    University dissertation from Stockholm : Karolinska Institutet, Department of Medicine at Huddinge University Hospital

    Author : Jakob Nilsson; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human Immunodeficiency Virus-1; Lymphoid tissue; cell mediated immunity; CD8 T-cells; perforin; cytotoxicity; regulatory T-cells; FOXP3;

    Abstract : CD8+ T-cell dependent clearance of microbial infections by perforin mediated killing of infected cells is a central component in the combat against viral infections. In HIV- 1 infected individuals the incidence of virus infected cells in lymphoid tissue, which is the major site for virus production, does not drop, but instead slowly increases as the disease progresses.

  5. 5. Cellular and molecular mechanisms in immune mediated hepatic fibrosis. A study of the inflammatory syndrome and fibrosis development of the NIF mouse liver

    University dissertation from Lund University, Faculty of Medicine

    Author : Julia Nilsson; [2020]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fibrosis; liver; mouse model; NKT cells; type 2 inflammation; inflammasome;

    Abstract : Fibrosis is the result of dysregulated inflammation and tissue repair, and is characterized by the excessive accumulation of extra cellular matrix (ECM) proteins. It causes detrimental effects to the afflicted tissue and can subsequently lead to organ failure. READ MORE
