  1. 1. Bone turnover markers and prediction of bone loss in elderly women

    Författare :Janaka Lenora; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone turnover markers; DXA; elderly; osteoporosis; scintigraphy; Bone mineral density; quantitative ultrasound of the calcaneus; bone loss;

    Sammanfattning : Around 70,000 osteoporosis-related fractures occur in Sweden annually and approximately half of the women in western world will sustain a fragility fracture after the age of 50 years. Fracture preventive efforts require the identification of individuals who are at high risk. LÄS MER

  3. 2. Osteoprotegerin in Bone Metabolism

    Författare :Helena Brändström; Uppsala universitet; []
    Nyckelord :Medical sciences; Bone; osteoprotegerin; osteoblasts; polymorphism; cytokines; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : Bone turnover, remodeling, is a constant process replacing old bone with new. This complex cellular event involves resorption by osteoclasts and formation of new bone by osteoblasts. The balance between osteoblastic and osteoclastic activity is under regulation by several endocrine and paracrine factors. LÄS MER

  4. 3. The effects of cyclosporin A on bone turnover and repair

    Författare :Anders Ekelund; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cyclosporin A; osteoinduction; osteoconduction; bone turnover; fracture healing; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

    Sammanfattning : The effects of cyclosporin A on bone metabolism are unclear and controversial. The aims of this thesis were to study the effects of cyclosporin A on bone turnover and on different repair processes such as fracture healing, osteoinduction and osteoconduction. LÄS MER

  5. 4. Bone density, bone geometry and bone development in young men - the importance of pubertal timing and fracture history

    Författare :Anna Darelid; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :peak bone mass; bone mineral density; bone development; fracture; young adulthood; men;

    Sammanfattning : Background and objective: Peak bone mass, the maximal bone mass attained in young adulthood, is an important factor of the lifetime risk of developing osteoporosis. The aim of this thesis was to study the development of bone mineral density (BMD) and bone geometry around the time of peak bone mass in men, and also to investigate the association between pubertal timing, fracture history, bone turnover markers and BMD and bone geometry in young men.

  7. 5. Mechanisms of Osseointegration: Experimental Studies on Early Cellular and Molecular Events in vivo

    Författare :Omar Omar; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegration; titanium; bone; gene expression; bone-implant interface; qPCR; inflammation; cytokine; chemotaxis; chemokine; integrin; bone formation; remodeling; in vivo; rat; immunohistochemistry; ultrastructure; biomechanical torque test;

    Sammanfattning : The early cellular and molecular activities determining the early tissue response and bone formation at bone/implant interface are not fully understood. The general aim of the current thesis was to develop a model for studying the early molecular and cellular activities in different bone types, and in response to different implant surface properties.
