  1. 16. Pathogenesis and Cell Biology of the Salmon Parasite Spironucleus salmonicida

    Författare :Ásgeir Ástvaldsson; Staffan Svärd; Jon Jerlström-Hultqvist; Scott Dawson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diplomonads; Spironucleus; Giardia; genome; annexin; oxygen stress; APEX; pathology;

    Sammanfattning : Spironucleus species are classified as diplomonad organisms, diverse eukaryotic flagellates found in oxygen-deprived environments. Members of Spironucleus are parasitic and can infect a variety of hosts, such as mice and birds, while the majority are found to infect fish. LÄS MER

  3. 17. Clinical grade vitrification of human ovarian tissue for fertility preservation

    Författare :Mona Sheikhi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cryopreservation of human ovarian tissue is one approach to preserve fertility for women who can be predicted to undergo premature ovarian failure as a consequence of chemotherapy, radiotherapy or genetic disorders. It is the most suitable option for pre-pubertal girls and for many young women to store oocytes. LÄS MER

  4. 18. Quantitative chemical imaging to study content release from single nanovesicles

    Författare :Tho D. K. Nguyen; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Exocytosis; Vesicle; Mass spectrometry imaging; Electron microscopy; Fluorescence microscopy; Electrochemical analysis; NanoSIMS;

    Sammanfattning : Cellular communication is vital for the survival of multicellular organisms. This process often relies on a highly regulated mechanism called exocytosis, which involves the release of chemical signals. During exocytosis, vesicles can fully or partially release their contents.

  5. 19. Characterizing cavity containing materials using electron microscopy : A study of metal oxides, mesoporous crystals and porous material containing nanosized metal-particles

    Författare :Miia Klingstedt; Osamu Terasaki; Syo Matsumura; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electron microscopy; Structural Chemistry; strukturkemi;

    Sammanfattning : This thesis concerns the characterization of novel materials by utilizing electron microscopy techniques. The examined materials contain cavities with certain attributes that enables desired properties for applications such as gas separation, catalysis and fuel cells. LÄS MER

  7. 20. Accumulation and Cellular Clearance of IAPP and Proteotoxicity of ATTR in Drosophila Models

    Författare :Xiaohong Gu; Gunilla Westermark; Anders Olofsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloid; IAPP; ATTR; ATTR amyloidosis; crystalline structure; aggrephagy; Drosophila melanogaster; Gal4-UAS; electron tomography; DAMS; SOHA; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Proteins’ functions are dependent on their three-dimensional (3D) structure. Under certain circumstances, proteins misfold and form aggregates, sometimes leading to amyloidosis. Islet amyloid polypeptide (IAPP) builds up amyloid in the pancreatic islet of patients with type 2 diabetes (T2D).
