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

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

    Sammanfattning : 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. LÄS MER

  3. 2. The periprosthetic femur fracture. A study from the Swedish National Hip Arthroplasty Register

    Författare :Hans Lindahl; Göteborgs universitet; []
    Nyckelord :periprosthetic femur fracture; loose stem; risk factors; patient outcome; THA;

    Sammanfattning : Post-operative periprosthetic femur fracture is a severe complication after total hip arthroplasty (THA).The incidence of periprosthetic femur fractures seems to be increasing because of several factors,including a growing population with THAs and an increasing life expectancy.

  4. 3. Clinical and experimental studies on total hip arthroplasty

    Författare :Sven-Arne Jacobsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : In a 12-year follow-up study, a low-friction, metal-on-plastic hip prosthetic system (Charnley) was compared with a high-friction, metal-on-metal prosthetic system (McKeeFarrar) in a consecutive series of 169 patients, mean age 67 at the start. Satisfactory results were reported in 92 percent of the patients. LÄS MER

  5. 4. Technology and systems for stump harvesting with low ground disturbance

    Författare :Simon Berg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Tree stumps could make a significant contribution to the transition from a fossil- to a bio-based economy, but current stump harvesting operations have adverse ecological effects. The ground disturbance caused by the up-rooting leads to increased carbon emissions from the soil and increases risks of leaching of heavy metals and nutrients, while removal of stump wood increases nutrient removal and reduces amounts of dead wood in the forest.

  7. 5. microRNAs: from biogenesis to organismal tracing

    Författare :Wenjing Kang; Marc Friedländer; Jens Lagergren; Ulf Ørom; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microRNA; microRNA biogenesis; taxonomical identification; high throughput sequencing; xenomiRs; RNA structure; high throughput screening; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : MicroRNAs (miRNAs) are short noncoding RNAs of around 22 nucleotides in length, which help to shape the expression of most mRNAs. Perturbation of miRNA expression has revealed a variety of defects in development, cell specification, physiology and behavior. LÄS MER
