INTRODUCTION Bone grafting is an integral part of orthopaedic surgery; the use of bone graft is increasing consistently in traumatology and also in complex revision surgeries of hip and knee arthroplasties. Considering this fact there is a need for some way to find solution for a bone graft which has more osteoinduction, osteoconduction as well as osteogenecity and also reduced rates of graft r...

Background & Objective: This study aimed to investigate the effect of decellularized allogeneic bone graft enriched by periosteal stem cells (PSCs) and growth factors on the bone repair process in a rabbit model, which could be used in many orthopedic procedures. Methods: In this experimental study, a critical size defect (CSD) (10 mm) was created in the ...

A new potassium persulfate redox system has been investigated for the graft polymerization of vinyl monomers. In this study potassium persulfate system was used for initiation the polymerization. Graft polymerization of acrylonitrile (AN) onto starch (Sta) was carried out in aqueous solution using potassium persulfate (I) redox system. It was found that the percentage of grafting and rate of gr...

there had been few if any study for second pancreas transplant outcome and consequences in patients with simultaneous kidney pancreas transplant after failure of the first pancreas allograft. the aim of this study was to compare the patient and graft survival and clinical outcomes and complication of the second pancreas transplant in patients with simultaneous kidney pancreas, compared with pan...

corneal transplantation is the most common and successful form of solid organ transplantation with a 2-year survival rate of over 90% in low risk cases. this high success rate may be due to the immune privileged status of the cornea, acaid (anterior chamber associated immune deviation) induction phenomena and secretion of inhibitory molecules by corneal cells such as il1-ra, il-1a and fas ligan...
