  1. 1. Functions of PDGF-A and -C. Essential ligands for the PDGF alpha receptor

    Författare :Hans Boström; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; platelet-derived growth factor; PDGF-A; PDGF-C; PDGF alpha receptor; extracellular retention; gene targeting; mouse development; epithelial-mesenchymal interaction; lung; alveolar formation; spina bifida; gastrointestinal villus;

    Sammanfattning : Altered protein kinase activity is a contributing factor in many diseases including most formsof human malignancies, and there is reason to believe that protein kinases will prove to be majordrug targets in the treatment of cancer. Protein kinases mediate most of the signal transduction ineukaryotic cells, regulating cellular events such as transcription, metabolism, proliferation,cytoskeletal rearrangement, migration, differentiation and apoptosis.

  2. 2. Reconstruction of the alveolar process in cleft patients

    Författare :Fatemeh Jabbari; Daniel Nowinski; Agneta Marcusson; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; alveolar bone grafting; dental status; initial cleft size; dental restoration; unilateral cleft lip and palate; cleft lip and alveolus; primary periosteoplasty; facial growth;

    Sammanfattning : Background. The treatment of patients born with cleft lip and palate has been gradually modified over the years as the surgical procedures have developed and improved. Multidisciplinary team care has evolved and provided improved care with enhanced results. Clefts in the alveolus can be reconstructed by alveolar bone grafting or by periosteoplasty. LÄS MER

  3. 3. Bone tissue regeneration indento-alveolar surgery : clinical and experimental studies on biomaterials and bone graft substitutes

    Författare :Annika Sahlin-Platt; Maria Ransjö; Christer Dahlin; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomaterials; bone graft substitutes; compomer; root end filling; Bio-Oss; Bioactive glass 45S5; Algipore; SEM EDAX; ICP-OES; Cryo-XPS;

    Sammanfattning : Pathological processes in the alveolar and facial bones can lead to bone loss that may not heal with complete regeneration. Biomaterials can be used to facilitate the healing process and/or as a bone substitute, but the mechanisms are not fully understood. LÄS MER

  4. 4. Gene expression during hard tissue formation

    Författare :Catharina Ellerström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :bone; dentin; mRNA; fibrillar collagens; osteonectin; fibronectin; development; rat;

    Sammanfattning : The purpose of this thesis was to study the formation of the extracellular matrix (ECM) of bone and dentin during development. Molecular techniques, such as in situ hybridization and RT-PCR, were used to investigate the occurrence of specific gene products in formative cells. LÄS MER

  5. 5. Palmitoylation and amyloid fibril formation of lung surfactant protein C

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

    Sammanfattning : Lung surfactant is a mixture of lipids and a few proteins, of which surfactant proteins (SP)-B and SP-C are lipophilic. Surfactant is essential for the reduction of surface tension at the alveolar air/liquid interface. LÄS MER
