  2. 1. The Role of Microvascular Pericytes in the Generation of Pro-fibrotic Connective Tissue Cells : Investigations in vitro and in Reactive Tissues in vivo

    Author : Jakob Karén; Christian Sundberg; Gunilla Westergren-Thorsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pericyte fibroblast differentiation fibrosis; Biochemistry; Biokemi; Microbiology; Mikrobiologi; Cell biology; Cellbiologi; Medical Biochemistry; Medicinsk biokemi; Cellforskning; Cell Research; Mikrobiologi; Microbiology;

    Abstract : Pericytes are cells of mesenchymal origin located on the abluminal side, juxtapositioned to the endothelial cells in capillaries, venules and small arterioles. They are important for maintaining vessel integrity in resting tissues as well as the formation and stabilization of new vessels. READ MORE

  4. 2. Lead(II) as a Tool for Probing RNA Structure in vivo

    Author : Magnus Lindell; Gerhart Wagner; Roland Hartmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; lead II cleavage; RNA structure; in vivo probing; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Abstract : Chemical modification and limited enzymatic hydrolysis are powerful methods to obtain detailed information on the structure and dynamics of RNAs in solution. In the work presented here I have taken advantage of the properties of the divalent metal ion lead(II) to establish it as a new probe for investigating the structure of RNA in vivo. READ MORE

  5. 3. Wear and Fixation of the acetabular component : in vivo evaluation of different polyethylenes and modes of fixation in total hip arthroplasty

    Author : Stephan Maximilian Röhrl; Kjell Gunnar Nilsson; Bo Nivbrant; Lars Nordsletten; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; total hip arthroplasty; acetabular component; wear; fixation; osteolysis; Radiostereometry; RSA; Kirurgi; Surgery; Kirurgi; ortopedi; Orthopaedics;

    Abstract : Polyethylene wear and micromotion of the implant play an important role in multifactorial etiology of osteolysis leading to aseptic loosening of the acetabular components. Despite excellent results in primary total hip arthoplasty in a 10-15 year perspective there are still unsolved problems. READ MORE

  6. 4. Comparative in vivo and in vitro studies on the biomechanics of maxillary partial dentures. A methodological and experimental study

    Author : Cláudio Pinheiro Fernandes; Lunds universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stomatology; biomechanics; Bite force; conical crowns; denture design; in vitro; in vivo; photoelasticity; strain gauges; Odontology; stress analysis.; Odontologi;

    Abstract : Biomechanical aspects are generally agreed to be significant, particularly during the planning of restorative treatments and the design of prosthetic appliances. However, comparative in vivo/in vitro studies show wide differences in the magnitudes and patterns of functional strains in prosthetic devices. READ MORE

  7. 5. Radiolabelled Oligonucleotides for Evaluation of in vivo Hybridisation Utilising PET Methodology

    Author : Gábor Lendvai; Mats Bergström; Sergio Estrada; Barbro Eriksson; Raymond Josephsson; Bertrand Tavitian; Uppsala universitet; []
    Keywords : Molecular medicine; Gene expression; Antisense oligonucleotides; Positron emission tomography; In vivo hybridisation; In vivo biodistribution; Chromogranin-A; 68Ga; RT-PCR; Scavenger receptors; Molekylärmedicin;

    Abstract : Antisense oligonucleotides (ODN) may interfere in gene expression on the basis of hybridising to its complementary messenger RNA (mRNA) sequence in the cell thereby preventing the synthesis of the peptide. Therefore, these ODNs may be potential drugs to treat human diseases by “knocking down” the expression of responsible genes or correcting the maturation process of mRNA in the field called antisense therapy.
