  1. 1. Hemodilution with dextran: Effects on blood flow and thrombus formation. An experimental study in the rabbit

    Författare :Lieselotte Frost-Arner; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; orthopaedics; Surgery; Hypertonic saline-dextran; Desmopressin; Heparin; Dextran; Rabbit; Synthetic vascular grafts; Blood flow; Hemodilution; Thrombus formation; Kirurgi; ortopedi; traumatologi; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Microvascular surgery enables free tissue flaps to cover tissue defects, e.g. after trauma and malignancies. Although major improvements in techniques have been made, problems with poor tissue circulation and thrombus formation still exist. LÄS MER

  3. 2. Regulation of morphogen signalling during neural patterning in the Xenopus embryo

    Författare :Hooi Min Tan Grahn; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Suppressor-of-fused; Gli; β-Catenin; Neural; Xenopus; FGF; Signalling; HtrA1; RDH10; Retinol dehydrogenase; Retinoic acid; Spemann s organizer; Induction; Gradient;

    Sammanfattning : Morphogens such as Hedghog, Wnt, FGF, and retinoic acid are important signals whose concentrations need to be tightly regulated in the vertebrate embryo to ensure body axis development and formation of the central nervous system. We first show that the intracellular cytoplasmic protein XSufu acts as a dual regulator of Hedgehog (Hh) and Wnt signals during neural induction and patterning in the Xenopus embryo. LÄS MER

  4. 3. Effects of high intensity focused ultrasound on the intervertebral disc

    Författare :Johan K Persson; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; tomography; radiology; Clinical physics; Biofysik; Biophysics; Thermal therapy; Disc herniation; Intervertebral disc; High intensity focused ultrasound; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : The purpose of this study was to study and try to optimise high intensity focused ultrasound treatment of the intervertebral disc. We demonstrated that it was possible to heat intervertebral discs with HIFU delivered by 50 or 5 mm diameter ultrasound transducers. LÄS MER
