  1. 16. Kalkputs- porstrukturens betydelse för beständighet

    Författare :Kristin Balksten; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kalkbruk; frostresistens; murning; kalkputs; hantverk; porstruktur; putsning;

    Sammanfattning : SammanfattningVid restaureringar av historisk kalkputs kan det vara svårt att uppnå den beständighet som är önskvärd. Idag händer det att nygjord kalkputs fryser ned efter bara ett par vintrar. För att förstå och lösa problemen kring kalkputs behöver problemet studeras ur olika synvinklar. LÄS MER

  3. 17. Regulation of exocytosis by Ca2+ and cAMP - A study on pancreatic beta- and alpha-cells

    Författare :Xiaosong Ma; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Endocrinology; secreting systems; type-2 diabetes; SUR1; Ca2 -channel; glucagon; exocytosis; insulin; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : Type-2 diabetes is characterized by impaired insulin secretion associated with excess glucagon release. Exocytosis of insulin- or glucagon-containing granules is initiated by Ca2+-influx through voltage-dependent Ca2+-channels and is modulated by the second messengers such as cAMP. LÄS MER

  4. 18. Processing of TNF-receptors to soluble receptor forms in myeloid cells

    Författare :Flemming Björnberg; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inflammation cytokine TNF receptor; extracellular fluids; Haematology; Hematologi; extracellulära vätskor;

    Sammanfattning : TNF (Tumor Necrosis Factor) is a pro-inflammatory cytokine which binds to two cell surface receptors, TNF-R55 and TNF-R75. The receptors undergo proteolytic cleavage and release a fragment (soluble TNF-receptors or TNF-Binding Protein), TNF-R55-BP and TNF-R75-BP. Soluble TNF-receptors are able to bind and inactivate TNF.

  5. 19. Structural Insights into the Acquisition and Storage of Iron

    Författare :Ulrika Schagerlöf; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Strukturkemi; Molecular biophysics; Molekylär biofysik; Structure chemistry; single particle; ferric reductase; human phagocyte superoxide-generating NADPH oxidase; frataxin; cryo electron microscopy; FRO2; iron homeostasis; iron acquisition;

    Sammanfattning : It is of vital importance to understand the systems for iron metabolism and this thesis contributes to this by providing insights into the structure and function of the acquisition and homeostasis of iron. The two proteins that have been primarily investigated are a ferric reductase from Arabidopsis thaliana called FRO2 and a mitochondrial iron chaperone from Saccharomyces cerevisiae called frataxin.

  7. 20. Structural and evolutionary studies of a lipocalin: the alpha1-microglobulin protein and its gene

    Författare :Annika Lindqvist; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; embryology human ; ontogeny; teratology; AMBP; Development biology; protein HC; bikunin; Utvecklingsbiologi; teratologi; embryologi människa ; Genetics; cytogenetics; Genetik; cytogenetik;

    Sammanfattning : a1-microglobulin is a small glycoprotein present in plasma and in tissues surrounding the gastrointestinal and respiratory tracts. a1-microglobulin is a member of the lipocalin protein family and exhibits several of the typical traits of a lipocalin; it binds an unknown ligand which causes the brown color of the protein, it forms complexes with various different proteins and there have been indications of the presence of a receptor for a1-microglobulin on T-lymphocytes.
