among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
Human mesenchymal stem cells (hMSCs) can be used for xenogenic transplantation due to their low immunogenicity, high proliferation rate, and multi-differentiation potentials. Therefore, hMSCs are an ideal seeding source for tissue engineering. The present study evaluates the reconstruction effects of hMSCs and osteoblast-like cells differentiated from hMSCs in poly-lactic-co-glycolic acid (PLGA...
OBJECTIVE Platelet-rich plasma (PRP) is considered to enhance bone formation especially at early stages of wound healing, depending on the limited and short life-span of platelets and growth factors. The aim of this study was to evaluate efficacy of double-application of PRP (DA-PRP) on bone healing in a rabbit calvarial defect model. STUDY DESIGN Twenty-eight rabbits, each had two surgically...
OBJECTIVE To review our experience of reconstructing the lateral and superior orbital walls after resection of sphenoid wing meningiomas. We will review the presentation and complications, examine the aesthetic results postoperatively, and compare preoperative and postoperative computed tomographic scans. To our knowledge, a comparative analysis of preoperative defect and postoperative reconstr...
