  1. 6. A comparative study of the mosses Ptychostomum pseudotriquetrum and P. bimum : Investigating morphological characters, habitat, and distribution across northern Sweden

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Isabell Sjölander; [2023]
    Nyckelord :Ptychostomum pseudotriquetrum; Ptychostomum bimum; Crypsis; Leaf decurrency; northern Sweden;

    Sammanfattning : The mosses Ptychostomum pseudotriquetrum and P. bimum (syn: Bryum, Bryophyta) are difficult to distinguish from each other, as they appear morphologically identical besides their difference in sexual condition. Because of their similarities, some researchers treat both as P. pseudotriquetrum, while others treat them as two distinct species. LÄS MER

  3. 7. Method development of magnetic cell isolation and DNA extraction of small cell populations from Ficoll-separated hematopoietic cells

    Kandidat-uppsats, Uppsala universitet/Institutionen för medicinsk cellbiologi

    Författare :Dominika Debowska; [2023]
    Nyckelord :Clonal haematopoiesis of indeterminate potential CHIP ; hematopoietic stem cell; automated cell separation; silica-membrane-based nucleic acid purification.;

    Sammanfattning : Clonal haematopoiesis of indeterminate potential, or CHIP are a family of mutations present in the general population. CHIP-mutations are prevalent in the haematopoietic stem cells and in the more mature cell populations, T-lymphocytes, B-lymphocytes and myeloid cells (CD3+, CD19+ and CD33+ cells) in blood. LÄS MER

  4. 8. The impact of human relevant mixture of contaminants on the development of human adipocytes

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Annika Jansson; [2023]
    Nyckelord :;

    Sammanfattning : The objective of this project was to investigate how organic anthropogenic chemicals (OCs) effect the differentiation of adipocytes in the human body. The objective is also to contribute to novel research in how groups of chemicals in our surrounding affect us. LÄS MER

  5. 9. Particle Detection in Bone Marrow Using CNNs and Transformer Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Anna Källén; Marcus Williams; [2023]
    Nyckelord :Bone Marrow; Dark Field Microscopy; Fourier Ptychography; Machine Learning; Convolutional Neural Networks; Transformer Networks; Quantisation; Technology and Engineering;

    Sammanfattning : The critical role of hematological stem cells, concentrated in bone marrow, in disease diagnosis makes the detection of these cells an imperative task. The current process, however, is slow and heavily reliant on expert interpretation, underscoring the need for automation. LÄS MER

  7. 10. The effect of calcium silicate-based cements on viability and differentiation of human stem cells from the dental apical papilla. : Future aspects in endodontic regeneration.

    Master-uppsats, Umeå universitet/Wallenberg centrum för molekylär medicin vid Umeå universitet (WCMM); Umeå universitet/Tandläkarutbildning

    Författare :Lahood Abdalla; Bagir Soltani; [2023]
    Nyckelord :MTA; Biodentine; SCAP; Regenerativ endodonti; endodonti; traumatiserade tänder; tänder; unga tänder;

    Sammanfattning : Introduction: Pulp necrosis in immature permanent teeth stops root development and may lead to higher risk of cervical fractures and a challenging treatment. Regenerative endodontic treatment (RET) aims to continue tooth development and implies the use of calcium silicate-based cements, such as Mineral trioxide aggregate (MTA) and Biodentine to seal the root canal.
