  1. 16. The role of computer-aided design and surface chemistry on Cell-scaffold interactions

    Författare :Sun Yang; Anna Finne-Wistrand; Ann-Christine Albertsson; Jinshan Pan; My Hedhammar; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amorphous degradable copolymer; aliphatic polyester; 3D fiber deposition; computer-aided design; Tween 80; BMSC; hOB; porous scaffolds;

    Sammanfattning : Cell interactions and cell response to three dimensional scaffolds based on poly(L-lactide-co-1,5-dioxepan-2-one) [poly(LLA-co-DXO)] and poly(L-lactide-co-e-caprolactone) [poly(LLA-co-CL)] wereimprovedstudiedby increasing surface hydrophilicity and by using computer-aided scaffold design. Different amounts of Tween 80 (3, 10, 20 wt%) were mixed with the copolymer and it was found that the water contact angle decreased significantly with the amount of Tween 80. LÄS MER

  3. 17. Water–fat separation in magnetic resonance imaging and its application in studies of brown adipose tissue

    Författare :Jonathan Andersson; Joel Kullberg; Håkan Ahlström; Mark Lubberink; Kerstin Lagerstrand; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brown adipose tissue; magnetic resonance imaging; water–fat signal separation; graph-cut; positron emission tomography; 18F-fludeoxyglucose; infrared thermography; machine learning; artificial neural networks; deep learning; convolutional neural networks; Radiology; Radiologi;

    Sammanfattning : Virtually all the magnetic resonance imaging (MRI) signal of a human originates from water and fat molecules. By utilizing the property chemical shift the signal can be separated, creating water- and fat-only images. LÄS MER

  4. 18. The effect of tobacco exposure on bone healing and the osseointegrationof dental implants

    Författare :Shariel Sayardoust; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; crevicular fluid; dental implants; gene expression; human; implant surfaces; implant survival; marginal bone loss; osseointegration; pain; periodontitis; resonance frequently analysis; smoking; titanium;

    Sammanfattning : Background: The mechanisms behind the impact of smoking on osseointegration are not fully understood. Aim: To correlate the clinical and molecular aspects of osseointegration in smokers compared with non-smokers. LÄS MER

  5. 19. Effects of Interleukin-4 and Interleukin-13 on Bone

    Författare :Carl-Johan Silfverswärd; Olle Nilsson; Östen Ljunggren; Kenneth Jonsson; Li Felländer-Tsai; Uppsala universitet; []
    Nyckelord :Medicine; Bone; Osteoblasts; Interleukin-4; Interleukin-13; Knockout; Medicin;

    Sammanfattning : Cytokines play important roles in bone metabolism, participating in the complex interplay necessary for normal bone formation and turnover. The aim of the present thesis was to investigate the effects of two anti-inflammatory cytokines, interleukin-4 (IL-4) and interleukin-13 (IL-13) on bone. LÄS MER

  7. 20. Biological aspects of synovial fluid mediated aseptic prosthesis loosening

    Författare :Martin Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Aseptic loosening; synovial fluid; osteoblasts; bone resorption; IGF;

    Sammanfattning : Aseptic prosthesis loosening is the most common reason for late failure of total hip arthroplasties. Resorption of the peri-prosthetic bone, resulting in a loose prosthesis is characteristic for aseptic loosening. LÄS MER
