  1. 1. On surgical techniques to increase bone density and volume. Studies in the rat and the rabbit

    Författare :Christer Slotte; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; autogeneic bone; bovine bone mineral; calvaria; cortical perforation; guided bone augmentation; maxilla; microangiography; morphometry; rabbit; rat; tibia; titanium implants; vessel topography;

    Sammanfattning : BACKGROUND. Various techniques of surgical intervention have been suggested to promote bone densityand volume; however, the predictability of such techniques is not always sufficiently supported by preclinicalevaluations.AIM. LÄS MER

  3. 2. The calcitonin gene family of peptides : receptor expression and effects on bone cells

    Författare :Susanne Granholm; Ulf Lerner; Pernilla Lundberg; Göran Andersson; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; CT family of peptides; osteoclast differentiation; bone resorption; CTR; CRLR; RAMPs; Cell biology; Cellbiologi;

    Sammanfattning : The calcitonin gene family of peptides consists of calcitonin (CT), two calcitonin gene related peptides (α-CGRP, β-CGRP), adrenomedullin (ADM), amylin (AMY), three calcitonin receptor activating peptides (CRSP1-3) and intermedin/adrenomedullin2 (IMD). These peptides bind to one of two G protein -coupled receptors, the calcitonin receptor (CTR) or the calcitonin receptor-like receptor (CRLR). LÄS MER

  4. 3. Biogenesis of tartrate-resistant acid phosphatase isoforms 5a and 5b in cell and animal models

    Författare :Serhan Zenger; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tartrate-resistant acid phosphatase (TRAP) is an iron-containing binuclear acid metallohydrolase that belongs to the purple acid phosphatase (PAP) family. It is a glycoprotein translated as a monomeric protein but is commonly isolated from tissues as a proteolytically processed dimeric form with increased enzyme activity. LÄS MER

  5. 4. Tissue responses to bone-implant biomaterials

    Författare :Haihong Liao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Gene expression; interface; mineralization; nacre; osteoblast; osteoclast; titanium;

    Sammanfattning : The purpose of the studies was to understand the mechanisms which underlie the interaction between tissue and bone-implant biomaterials. Tissue and naturally occurring aragonite nacre interaction was systematically studied for the first time by combined histological examination, cellular and molecular biological approaches. LÄS MER

  7. 5. Cellular mechanisms involved in bone resorption

    Författare :Ulf Lerner; Umeå universitet; []
    Nyckelord :Bone resorption. cyclic AMP; parathyroid hormone; prostaglandins; la OH D3; lysosomal enzyme release; osteoclast; periodontitis; rheumatoid arthritis;

    Sammanfattning : The effects of parathyroid hormone (PTH), prostaglandins (PGE1, PGE2, PGF2a), cAMP, cAMP-analogues, phosphodiesterase (PDE) inhibitors and la (OH) D3 on bone resorption and associated cellular process have been studied in a bone organ culture system using half- calvaria from 6-7 day-old mice. Bone resorption was assessed by determining the release of calcium (Ca2+), inorganic phosphate (Pi) and 45Ca from the calvarial bones to the culture media. LÄS MER
