  2. 1. Form and Finish of Implants in Uncemented Hip Arthroplasty : Effects of Different Shapes and Surface Treatments on Implant Stability

    Author : Stergios Lazarinis; Nils P. Hailer; Lars Weidenhielm; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Form; Finish; Total hip arthroplasty; Swedish Hip Arthroplasty Register; Hydroxyapatite; RSA; DXA; BMD; Stability.; Orthopaedics; Ortopedi;

    Abstract : The design of an uncemented hip arthroplasty implant affects its long-term survival. Characteristics such as the form and the finish of the implant are crucial in order to achieve the best possible conditions for long-term implant survival. READ MORE

    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; acoustic velocity; Betula spp.; dynamic MOE; genetic parameters; grain angle; hardwood; Itrax densitometry; mixed forests; non-destructive testing; stem form; akustisk velocitet; Betula spp.; blandskog; densitometri; genetiska parametrar; icke destruktiva metoder; Itrax; lövträ; skogsodling; stamkvalitet; vedsegenskaper; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Swedish tree species of birch (silver: Betula pendula and downy: B. pubescens) are often neglected during forest management activities, resulting in low value logs. This thesis investigated birch stem characteristics and wood properties important for solid wood products, in genetics and management trials in southern Sweden. READ MORE

  5. 3. Molecular regulation of hematopoietic stem cells

    Author : David Bryder; Avdelningen för molekylär hematologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematologi; extracellulära vätskor; extracellular fluids; Haematology; bone marrow transplantation; cytokines; Hematopoiesis; stem cells;

    Abstract : Hematopoietic stem cells (HSCs) are ultimately responsible for the all mature blood cell production. They can primarily be found in the bone marrow (BM) at a low frequency (~0.02%). READ MORE

  6. 4. Influence of postoperative treatment, surface treatment and stem design on the outcome of primary total hip arthroplasty

    Author : Truike Thien; Göteborgs universitet; []
    Keywords : Primary total hip arthroplasty; anteverted stem; stem design; cemented and cementless fixation; radiostereometry; bone mineral density; clinical outcome;

    Abstract : Aims: The aim of this study was to investigate the influence of postoperative treatment, surface treatment and stem design on the outcome of primary Total Hip Arthroplasty. The main intention was to study anteverted femoral stems. READ MORE

  7. 5. Dental mesenchymal stem cells

    Author : Nina Kaukua; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Mesenchymal stem cells have been found in various tissues and act as source for renewal and repair. The mouse incisor tooth continuously grows throughout life, implicating that there are stem cell niches constantly contributing with cells. The composition of these stem cell niches is not fully understood. READ MORE
