  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. 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

  5. 4. Orthodontically induced root resorption: a clinical and radiographic survey

    Författare :Dimitrios Makedonas; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthodontics; root resorption; prediction; CBCT; Angle Class I; fixed appliance; six month; risk factors;

    Sammanfattning : In 2005 the Swedish Council on Health Technology Assessment (SBU), in a systematic review, Malocclusions and Orthodontic Treatment in a Health Perspective, concluded that there were low or contradicted evidence for an association between orthodontic treatment and the risks for negative side effects. The aims of this study was to evaluate the perception of Greek and Swedish orthodontic practitioners view on orthodontically induced root resorption (OIRR), to investigate how root resorption is handled in a large orthodontic clinic and to prospectively study and correlate the prevalence and severity of root resorption seen after an initial treatment period and at the end of treatment, in a cohort of patients treated with fixed appliance.

  7. 5. Population Differentiation in Solidago virgaurea along Altitudinal Gradients

    Författare :Anna Bergsten; Jon Ågren; Staffan Karlsson; Kari Lehtilä; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population differentiation; altitudinal gradient; plant nutrient status; resorption efficiency; resorption proficiency; flowering phenology; countergradient variation; reproductive effort; flower production; cost of reproduction; Biology; Biologi; Other biology; Övrig biologi; Ecological Botany; Ekologisk botanik;

    Sammanfattning : Altitudinal gradients offer attractive opportunities for studies of population differentiation in response to environmental heterogeneity. In this thesis, I examined population differentiation along altitudinal gradients by combining common-garden experiments with field studies and experiments in alpine, subalpine and boreal populations of the perennial herb Solidago virgaurea.
