  1. 1. Toll-like receptors (TLRs) and inflammatory bone modeling

    Författare :Ali Kassem; Ulf Lerner; Pernilla Lundberg; Pedro Souza; Timothy Arnett; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toll-like receptor; osteoclast; osteoblast; bone resorption; bone formation; P. gingivalis; S. aureus; flagellin.;

    Sammanfattning : Patients with inflammatory or infectious conditions such as periodontitis, peri-implantitis, osteomyelitis, rheumatoid arthritis, septic arthritis and loosened joint prosthesis display varying severity of destruction in the adjacent bone tissue. Bone loss in inflammatory diseases is considered a consequence of cytokine induced RANKL and subsequent enhanced osteoclast formation. LÄS MER

  3. 2. Diffusion in Bone Tissue

    Författare :Gustav Lindberg; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone growth; diffusion; stress enhanced; finite element method; steady-state; periosteal membrane; diffusion in bovine bone; diffusion experiment; Conductivity measurement; Fick’s law; Fourier series; Kalman filter; transient solution;

    Sammanfattning : In order to prevent or modify the processes of bone degeneration the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. LÄS MER

  4. 3. Chemokines and bone : lessons from in vitro and in vivo studies

    Författare :Sara Rosendahl; Pernilla Lundberg; Cecilia Koskinen Holm; Elin Kindstedt; Marie Lagerquist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Bone homeostasis is maintained by the balanced activity of bone-forming osteoblasts and bone-resorbing osteoclasts. Inflammation in the vicinity of bone disturbs the balanced bone remodeling process, which often results in bone loss. LÄS MER

  5. 4. On the Growth of Bone through Stress Driven Diffusion and Bone Generation Processes

    Författare :Gustav Lindberg; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone growth; Osteogenesis; Diffusion in bone; stress enhanced diffusion; Ginzburg-Landau; phase-field; diffusion experiment; Conductivity; Kalman filter; finite element method; Fourier series; Fick’s law; Osteology;

    Sammanfattning : In order to prevent or modify bone degeneration due to rest or due to diseases such as osteopenia and osteoporosis, the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. LÄS MER

  7. 5. Modeling human gut microbiota: from steady states to dynamic systems

    Författare :Hao Luo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dynamics.; metabolic modeling; genome-scale metabolic model; gut microbiota; cybernetic model;

    Sammanfattning : Human gut microbes are an essential part of human sub-microscopic systems and involved in many critical biological processes such as Type 2 diabetes (T2D) and osteoporosis. However, the underlying mechanisms are unclear. LÄS MER
