Background: Kidney transplantation had been evaluated in some researches in Iran mainly with clinical approach. In this research we evaluated graft survival in kidney recipients and factors impacting on survival rate. Artificial neural networks have a good ability in modeling complex relationships, so we used this ability to demonstrate a model for prediction of 5yr graft survival after ki...

among the synthetic polymers, poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (phbv) microbial polyester is one of the biocompatible and biodegradable copolymers in the nanomedicine scope. phbv has key points and suitable properties to support cellular adhesion, proliferation and differentiation of nanofibers. nanofibers are noticeably employed in order to enhance the performance of biomaterials,...

One of the main issues in neural grafting technology is the optimization of graft survival and integration into the host brain, prerequisites for the establishment of a functional host-graft relationship. Optimal integration of the transplanted cells is the result of axonal growth from the transplant and the regeneration of axons from host neurons damaged during the transplantation procedure. G...

BACKGROUND Neural cell transplantation is a promising therapy for stroke, but rejection of human cells in animal models is an obstacle to furthering this research. Many antirejection strategies have been reported, but few comparison data are available. We asked if human neural cell grafts would have different survival or differentiation with injected or oral cyclosporine regimens. METHODS Rat...

Neural progenitor cells grafted to sites of spinal cord injury have supported electrophysiological and functional recovery in several studies. Mechanisms associated with graft-related improvements in outcome appear dependent on functional synaptic integration of graft and host systems, although the extent and diversity of synaptic integration of grafts with hosts are unknown. Using transgenic m...

Current restorative neurotransplantation research focuses mainly on the potential of the neural graft to replace damaged or missing cell populations and to deliver needed gene products in the form of transgenes. Because of this graft-oriented bias of the procedure, possible dormant regenerative capabilities within the host have been largely underestimated and dismissed as insignificant. This re...

BACKGROUND Delayed graft function (DGF) is one of the most important complications in the post-transplant period, having an adverse effect on both the immediate and long-term graft survival. In this study, an artificial neural network was used to predict the occurrence of DGF and compared with traditional logistical regression models for prediction of DGF. METHODS A total of 304 cadaveric ren...

PURPOSE An improved translocation technique for autologous retinal pigment epithelium (RPE) transplantation is presented. The graft consists of a sheet of a partial-thickness choroid with RPE attached. METHODS Twenty-seven pigmented rabbits were used in this study. After mechanical debridement of Bruch membrane, partial-thickness RPE-choroid sheets were transplanted onto the subretinal space ...

We have investigated dorsal root ganglion formation, in the avian embryo, as a function of the composition of the paraxial somitic mesoderm. Three or four contiguous young somites were unilaterally removed from chick embryos and replaced by multiple cranial or caudal half-somites from quail embryos. Migration of neural crest cells and formation of DRG were subsequently visualized both by the HN...
