  2. 21. Nanostructured Ceramics - Synthesis and Understanding

    Author : Farnaz Ghajeri; Wei Xia; Freddy Kleitz; Uppsala universitet; []
    Keywords : Material Science; Nanoporouse Silica; Calcium Phosphate; Synthesis; Characterization; Adsorption; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : During the last years, nanostructured ceramics have been favored for use in the industry due to their beneficial properties. For example, calcium phosphate ceramics with their biocompatible and bioactive characteristics are beneficial in biomedicine. READ MORE

  4. 22. Ceramic Core–Shell Particles : Synthesis and Use within Dentistry

    Author : Camilla Berg; Wei Xia; Håkan Engqvist; Nicola Döbelin; Uppsala universitet; []
    Keywords : Calcium phosphate; Core-shell particles; Substituting ions; Dentin hypersensitivity; Occlusion; Mineralization; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Dentin hypersensitivity is one of the most prevalent conditions related to oral health, affecting a large share of the adult population. Shortcomings with the available treatment options are related to non-ideal particle sizes and degradation properties. READ MORE

  5. 23. Enhanced phosphorus removal from wastewater using virgin and modified slags : performance, speciation and mechanisms

    Author : Minyu Zuo; Gunno Renman; Jon Petter Gustafsson; Lars Lövgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AOD; EAF; BFS; Calcium phosphate; XANES; slag mineralogy; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : Argon oxygen decarburization slag (AOD) was tested in batch and column experiments to investigate its phosphorus (P) removal performance. The effects of factors such as AOD dose, initial P concentration of the feeding solution, and aging on the P removal ability of the slags were analyzed. READ MORE

  6. 24. Aspects of Fibroblast Growth Factor 23 in Mild to Moderate Renal Dysfunction

    Author : Per-Anton Westerberg; Torbjörn Linde; Östen Ljunggren; Björn Wikström; Marcus Ketteler; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FGF23; phosphate; mineral metabolism; elderly; mortality; Medicin; Medicine;

    Abstract : Disturbances in mineral metabolism contribute to vascular calcification and mortality risk in chronic kidney disease (CKD). Serum levels of fibroblast growth factor (FGF)23, a bone derived, phosphaturic peptide, are associated with cardiovascular mortality in CKD. READ MORE

  7. 25. Molecular and structural patterns of guided bone regeneration (GBR). Experimental studies on the role of GBR membrane and bone substitute materials

    Author : Ibrahim Elgali; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regenerative medicine; biomaterials; bone substitute; calcium phosphate; guided bone regeneration; membrane; strontium; bone defect; bone remodeling; inflammation; cytokines; chemokines; growth factors; gene expression; histomorphometry; in vivo;

    Abstract : The mechanisms of guided bone regeneration (GBR) and bone healing with calcium phosphate (CaP) bone substitutes are not fully understood. The major aim of this thesis was to determine the relationship between the bone formation in bone defects and the cellular distribution and activities in association with CaP materials and/or with GBR membrane.
