  2. 2. Effects of growth hormone on bone tissue in transgenic mice

    Detta är en avhandling från Göteborg

    Författare :Jonas Sandstedt; Göteborgs universitet.; Gothenburg University.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; bone; ovariectomy; orchidectomy; growth; Interleukin-6; titanium; transgenic mice;

    Sammanfattning : Growth hormone (GH) affect bone-tissue in both humans and rodents. Also sex steroids are important for growth and the maintenance of normal bone physiology. The specific aims of this study were to investigate how high levels of GH affects bone tissue in mice and to determine whether these effects are dependent on an intact gonadal function. LÄS MER

  3. 3. Modelling loading and growth of long bones Modelling loading and growth of long bones

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Priti Yadav; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Growth Plate; Finite element analysis; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : The long bones grow by the process of endochondral ossification, which occurs at the growth plate. This process is regulated by biological factors and mechanical factors. The biological factors which contribute to endochondral ossification process are genes, hormones, nutrients etc. The mechanical factor is the load acting on the bone. LÄS MER

  4. 4. The role of estrogen receptor alpha in the regulation of bone and growth plate cartilage

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Anna E Börjesson; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; estrogen receptor α; bone; growth plate; estrogen;

    Sammanfattning : Estrogens are important endocrine regulators of skeletal growth and maintenance in both females and males. Studies have demonstrated that the estrogen receptor (ER)-α is the main mediator of these estrogenic effects in bone. Therefore, estrogen signaling via ERα is a target both for affecting longitudinal bone growth and for bone remodeling. LÄS MER

  5. 5. The role of apoptosis in growth plate cartilage during normal and abnormal growth

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Women's and Children's Health

    Författare :Dionisios Chrysis; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apoptosis; growth plate; dexamethasone; cytokines;

    Sammanfattning : Longitudinal bone growth occurs at the growth plate where resting chondrocytes proliferate, differentiate into a hypertrophic form, and finally become terminal hypertrophic chondrocytes before giving rise to bone. Because growth occurs when proliferation exceeds cell death, alterations in cell death by apoptosis, which is essential for the maintenance of tissue homeostasis, could affect growth. LÄS MER
