  1. 1. Integrated biomechanical, electronic and topographic characterization of titanium dental implants

    Författare :Johanna Löberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface roughness parameters; 3D-SEM; AFM; Interfacial shear strength; Impedance spectroscopy; Cyclic voltammetry; SBF; MG-63; TiO2-nanoparticles;

    Sammanfattning : Titanium dental implants are medical devices used to restore the function entailed with the loss of one or several teeth. To obtain successful function over long periods, the dental implants must be sufficiently anchored in the bone to withstand the forces induced by for example chewing. LÄS MER

  3. 2. Kinins : important regulators in inflammation induced bone resorption

    Författare :Anna Bernhold Brechter; Ulf Lerner; Hans-Erik Claesson; Umeå universitet; []
    Nyckelord :Bone resorption; Osteoblasts; Kinins; B1 and B2 receptors; IL-1β; TNF-α; Prostaglandin; COX-2; RANKL; Transcription factors; IL-4; IL-13; Medical Cell Biology; medicinsk cellbiologi;

    Sammanfattning : Inflammatory processes in, or in close vicinity of, the skeleton often lead to loss of bone tissue. Different cytokines have been shown to be involved as stimulators of inflammatory induced osteoclastic bone resorption. LÄS MER

  4. 3. Vitamin A and Osteoporosis : Experimental and Clinical Studies

    Författare :Sara Johansson; Håkan Melhus; Andreas Kindmark; Monica Lind; Göran Toss; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal medicine; vitamin A; bone; osteoporosis; Invärtesmedicin; Internal medicine; Invärtesmedicin;

    Sammanfattning : Vitamin A in high doses is severely toxic to the rat skeleton, and the active metabolite retinoic acid (RA) can induce bone resorption in vitro. An excessive dietary intake of vitamin A has been associated with reduced bone mineral density and an increased risk of hip fracture. LÄS MER

  5. 4. Bio-based nonionic antimicrobial polymers with isatin or indole functionality

    Författare :Xiaoya Li; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antimicrobial polymers; nonionic; isatin; indole; miscibility; hemolytic activity; cytotoxicity;

    Sammanfattning : Infections by pathogenic microorganisms remain one of the most serious concerns in several areas, particularly in hygienic applications. Antimicrobials have been used to combat these infections. Using small molecular antimicrobials as additives or coatings is an industrially adopted strategy. LÄS MER

  7. 5. Insulin-coated titanium implants - a potential therapy for local bone regeneration

    Författare :Behnosh Öhrnell Malekzadeh; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Insulin; Titanium; Bone; Implant; Osteoblast; Immobilisation;

    Sammanfattning : Background: Insulin is a hormone that regulates glucose metabolism, however, it is also important for bone formation. The anabolic effect of insulin on bone could open up alternative therapies when it comes to local bone regeneration. However, this requires a method for local administration of insulin. LÄS MER
