  2. 1. Macrophage-material surface interactions

    Author : Christina Gretzer; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apoptosis; biomaterials; cell-cell interactions; cell-material interactions; cytokines; differentiation; fibrinogen; hydrogen peroxide; LPS; monocytes; particles;

    Abstract : Material surface-stimulated activation of the macrophage and the release of mediators has been suggested to be an important factor for inflammation and tissue regeneration around biomedical implants. Macrophage interactions with particles released from implants as well as macophage-bacteria interactions are also involved in implant loosening processes. READ MORE

  4. 2. A Chloroplast Localized Small Heat Shock Protein, Hsp21. Importance of Hsp21 in stress protection of transgenic Arabidopsis thaliana, recombinant expression and characterization of oxidation-dependent conformational changes

    Author : Ulrika Härndahl; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; a-crystallin; sHsp; chaperone; amphipathic a-helix; oligomer; redox-regulated; methionine sulfoxidation; oxidative stress; regulation; protein structure; circular dichroism; mass spectrometry; fluorescence spectroscopy; Biochemistry; Metabolism; Biokemi;

    Abstract : A specific group of heat shock proteins, the so called small heat shock proteins (sHsps), exists in all organisms but are especially abundant in plants. The sHsps prevent aggregation of other proteins (substrate proteins) during transient heat and oxidative stress. READ MORE

  5. 3. Changed iron metabolism and iron toxicity in scrapie-infected neuroblastoma cells

    Author : Sandra Zetterström Fernaeus; Tiit Land; Gaetano Cairo; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prion disease; oxidative stress; iron metabolism; Neurochemistry; Neurokemi;

    Abstract : Reactions and interactions of iron and oxygen can be both beneficial and detrimental to cells and tissues. Iron is mainly found in our blood where it functions as a mediator in the transport of oxygen to the cells and is further vital for the cellular respiration reducing the oxygen to water. READ MORE

  6. 4. Heme Protein Biogenesis - Catalase in Enterococcus faecalis

    Author : Michael Baureder; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Enterococcus faecalis; heme proteins; protein assembly; oxidative stress; catalase; cytochrome;

    Abstract : Heme proteins form a large and diverse group of proteins which are involved in a variety of biological functions. The heme prosthetic group enables them to carry out redox reactions, transport electrons, bind gaseous molecules, and function as sensors. Despite their importance only little is generally known about heme protein biogenesis. READ MORE

  7. 5. Effects of sex steroids on normal human breast : studies in vivo using microdialysis and in vitro in cell culture

    Author : Charlotta Dabrosin; Bo von Schoultz; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Prolonged exposure to sex steroids may constitute a risk factor for the development of breast cancer. The biological mechanisms involved in breast carcinogenesis are not well understood. READ MORE
