  1. 31. Ribosome Associated Factors Recruited for Protein Export and Folding

    Författare :Amanda Raine; Jarl Wikberg; Harris Bernstein; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; Signal recognition particle; trigger factor; ribosomes; protein folding; membrane targeting; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Sammanfattning : Protein folding and export to the membrane are crucial events in the cell. Both processes may be initiated already at the ribosome, assisted by factors that bind to the polypeptide as it emerges from the ribosome. LÄS MER

  3. 32. Regulating Gene Expression to Promote Osteoblastic Differentiation of Stem Cells

    Författare :Maruthibabu Paidikondala; Oommen P. Varghese; Jöns Hilborn; Laura Creemers; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Sammanfattning : Bone is a tissue that heals by itself, unless the defect is too large (critical size). Today, novel regenerative medicine approaches have emerged as an alternative to treat such defects. This thesis explores alternative therapeutic strategies for bone tissue engineering which are biocompatible and clinically translatable. LÄS MER

  4. 33. Controlled Degradation of Polyester-Ethers Revealed by Mass Spectrometry Techniques

    Författare :Anders Höglund; Ann-Christine Albertsson; Jukka Seppälä; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Degradation products; biocompatibility; -caprolactone; 1; 5-dioxepan-2-one; 6-hydroxyhexanoic acid; 3- 2-hydroxyethoxy propanoic acid; oligomers; Polymer chemistry; Polymerkemi;

    Sammanfattning : The use of degradable biomedical materials in e.g. tissue engineering and controlled drug delivery has changed medical science during recent decades. The key question is to adapt the material with respect to mechanical properties, surface characteristics, and degradation profile to suit its intended application. LÄS MER

  5. 34. Open-tubular columns for liquid and supercritical fluid chromatography

    Författare :Karel Janák; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Methods have been developed for the preparation of narrow-bore open tubularcolumns. In this content, condensed gases (butane, chloroethane and Freon114) were used as solvents for the static coating of these columns. Adevice for filling the narrow-bore open tubular columns with solutions incondensed gases has been designed. LÄS MER

  7. 35. Hygro- and hydroexpansion of paper : Influence of fibre-joint formation and fibre sorptivity

    Författare :Per A. Larsson; Lars Wågberg; Kaarlo Niskanen; KTH; []
    Nyckelord :;

    Sammanfattning : Paper is a versatile, cheap and environment-friendly material. Nevertheless, there are several factors limiting its usefulness, and one of the major issues is that cellulosic and ligno-cellulosic fibres spontaneously sorb water. At the same time, the water uptake changes the dimensions of the paper. LÄS MER
