  2. 6. Calcium Phosphate Based Biomaterials for Bone Augmentation

    Author : Jun Luo; Cecilia Persson; Håkan Engqvist; Marc Bohner; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone substitute materials; calcium phosphate cements; apatite; brushite; monetite; setting mechanism; premixed; fibre reinforcement; composite; silk fibroin; mechanical properties; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Basic (apatite-based) calcium phosphate cements (CPCs), and acidic (brushite and monetite-based) CPCs are used as bone replacement materials because of their bioactivity, mouldability and ability to harden in place. However, their application is limited by their inherent brittleness and difficulties related to their handling. READ MORE

  4. 7. Injectable Calcium Phosphate Bone Substitute In Distal Radial Fractures

    Author : Philippe Kopylov; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Norian SRS; Bone substitute; radius fracture; injectable; calcium phosphate; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Abstract : Fractures of the distal end of the radius are common and occur in many different forms. The long-term results after conservative treatment of fracture of the distal end of the radius in younger adults with special reference to degenerative changes and function are investigated in 76 patients (Paper I).

  5. 8. Calcium Homeostasis After Thyroid Surgery

    Author : Pia Lindblom; Lund Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PTH-peripheral effects; hPTH- 1-34 infusion; EDTA infusion; Set-point; Vitamin D3; PTH; Calcium; Thyroid surgery; Postoperative hypocalcemia; Bone density.; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Reduced thyroid hormones;

    Abstract : Calcium homeostasis after thyroid surgery was studied during the immediate postoperative period and after one year. One day after hemithyroidectomy ionised calcium decreased whereas basal PTH did not change. EDTA stimulated maximal and total PTH secretion and set-point decreased on postoperative day 1 and normalised on day 7. READ MORE

  6. 9. Enhancing material and biological properties of calcium phosphate bone substitute

    Author : Christopher Camire; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; materialteknik; Non-metallic mineral technology; Icke-metallisk mineralteknik; Biotechnology; Bioteknik; Materiallära; Material technology; Technological sciences; Teknik; Naturvetenskap; reumatologi; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Natural science; muskelsystem; Skelett; muscle system; rheumatology locomotion; Bone Substitute; Calcium Phosphate; Skeleton; Medicin människa och djur ; Medicine human and vertebrates ; Osteoconductivity; Silicon; Mechanical Properties; Crystallinity; Reactivity; Calorimetry; Hydroxyapatite;

    Abstract : Calcium phosphate materials (CaPs) have proven biocompatible and useful in clinical situations. One CaP showing promise in the clinic is alpha phase tricalcium phosphate ([alpha]-TCP). [alpha]-TCP in powder form can be hydrated and undergoes a reaction resulting in calcium deficient hydroxyapatite (CDHA). READ MORE

  7. 10. Solubility and Surface Complexation Studies of Apatites

    Author : Åsa Bengtsson; Staffan Sjöberg; Per Persson; Lars Lövgren; Laurent Charlet; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; apatite; dissolution; calcium; phosphate; fluoride; goethite; surface complexation; speciation; outer-sphere complexation; FTIR; XPS; potentiometry; Chemistry; Kemi;

    Abstract : Apatites are a diverse class of phosphate minerals that are important in a great variety of natural and industrial processes. They are, for example, used as raw material in fertiliser production and in the remediation of metal-contaminated soils. READ MORE
