  2. 1. Lipoprotein lipase : mechanism for adaptation of activity to the nutritional state

    Author : Gengshu Wu; Thomas Olivecrona; Gunilla Olivecrona; Peter Nisson-Ehle; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; adipose tissue; heparin; extracellular; nutrition; turnover; actinomycin; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : Lipoprotein lipase (LPL) is an enzyme to hydrolyze triglycerides in lipoproteins and thereby make the fatty acids available for cellular metabolic reactions. Short-term fasting down-regulates LPL activity in adipose tissue. This regulation is through post-translational mechanism. READ MORE

  4. 2. The impact of tourniquet use in total knee arthroplasty

    Author : Charlotta Olivecrona; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Use of the tourniquet in extremity surgery is considered to be an important tool because it prevents intraoperative bleeding and thereby improves visualization of the surgical field. However, its use is not without risks, and complications may occur. READ MORE

  5. 3. Coronary Reactive Hyperemia

    Abstract : Introduction: The mechanism of post ischemic reactive hyperemia is still unknown but now thought to be multifactorial and perhaps involving purinergic signalling. Purines such as ATP and ADP have recently been discovered to play a vital role in the regulation of vascular tone. READ MORE

  6. 4. Assessment of acetabular cup position with computed tomography

    Author : Henrik Olivecrona; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Revision of Total Hip Arthroplasty (THA) due to loosening is necessary in many patients. Diagnosis is usually late with significant bone and soft tissue destruction. Available diagnostic techniques are either not sensitive enough or too complicated and expensive for routine use. READ MORE

  7. 5. A new computed tomography method for evaluation of orthopedic implants : applied to the acetabular cup

    Author : Lotta Olivecrona; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Two major long term complications after total hip arthroplasty (THA) is aseptic loosening and wear of the implant. In the clinical situation a detection level of approximately 1 mm is desirable. However, conventional planar radiographs used in clinical routine cannot reach this level. READ MORE
