11. Advances in Bone Tissue Engineering
Sammanfattning : Bone deficiencies, caused by malformations, trauma or adverse effects from medical treatments, are a clinical challenge and often associated with reduced physical function and quality of life. Autologeous bone grafts can be used to reconstruct skeletal defects, but the right size and quality of bone might not always be available and even so, donor-site morbidity might follow. LÄS MER
12. On enhancement of bone formation using local drug delivery systems
Sammanfattning : Introduction: Despite that many reports have confirmed the long-term clinical success rates associated with implant treatment, implant failure to achieve and maintain osseointegration still occurs in many cases. Local and sustained drug release at the bone-implant interface is one of the strategies that have been suggested to improve the osseointegration. LÄS MER
13. Enhancing material and biological properties of calcium phosphate bone substitute
Sammanfattning : 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). LÄS MER
14. The roles of osteoclasts and RUNX2 in the progression of prostate cancer bone metastases
Sammanfattning : Metastasis to the skeleton is the major cause of death from prostate cancer (PC). Patients with metastatic PC are treated with androgen deprivation therapy (ADT) to decrease testosterone levels and thereby inhibit further growth of the tumor. LÄS MER
15. On platelet-rich plasma in reconstructive dental implant surgery
Sammanfattning : Abstract Background Severe athrophy of the edentulous maxilla may require augmentation before implants can be placed. Autogenous bone has been used for reconstruction in block or in particulated form. LÄS MER
