  1. 41. Processing, stability and interactions of lung surfactant protein C

    Författare :Jing Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mature SP-C is a 4.2 kDa transmembrane protein which is uniquely expressed in the alveolar type II cell. Human SP-C is generated via multistep proteolytic cleavage of both the C-terminal and Nterminal regions of proSP-C. LÄS MER

  3. 42. Metalloproteinases in development and disease

    Författare :Zhongjun Zhou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Metalloproteinases are Zn-dependent proteases composed of five superfamilies. One important subfamily is the matrix metalloproteinases (MMPs) that process various components of the extracellular matrix (ECM) and non-ECM proteins. LÄS MER

  4. 43. Studies on human sterol 27-hydroxylase with emphasis on its mechanism of regulation and metabolic consequences of a deficient enzyme

    Författare :Magnus Hansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Sterol 27-hydroxylase (CYP27A1) is a mitochondrial cytochrome P-450 enzyme present in most animal cells. In hepatocytes, CYP27A1 has an important role in connection with biosynthesis of bile acids from cholesterol. LÄS MER

  5. 44. On tissue reactions to and resorption of bone substitutes

    Författare :Arne Mordenfeld; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone graft; bone substitutes; sinus floor augmentation; lateral ridge augmentation;

    Sammanfattning : Background: The increasing need for bone grafting procedures inimplant dentistry and the introduction of a variety of bone substitutesrequire a deeper understanding of the biological response and shortandlong-term behaviour of these materials to choose the adequategraft and surgical procedure for the intended clinical application.Aims: The overall aim was to clinically and histologically studythe short- and long-term tissue reactions to and resorption of bonesubstitutes after bone augmentation.

  7. 45. Functional importance of estrogen receptors in the periodontium

    Författare :Daniel Nebel; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Estrogen; Estrogen receptors; LPS; Periodontium; PDL cells; Gingival epithelial cells;

    Sammanfattning : Östrogen är ett kvinnligt könshormon som även har andra effekter. Östrogen verkar i cellkärnan genom att binda till en östrogenreceptor (ER), som finns i två olika typer, ERα och ERβ. Parodontit (tandlossning) är en inflammationssjukdom som drabbar tandens fäste som svar på bakterier som normalt finns i munhålan. LÄS MER
