The purpose of this research article is to present the functionalization a new titanium alloy system TiNbZr, by grafting bioactive polymer (poly(sodium styrene sulfonate), PNaSS) using “grafting from” technique improve osseointegration. resulting grafted covalently bonded substrate in procedure thanks surface-induced polymerization. Colorimetric assay, Fourier-transform infrared spectra recorde...

BACKGROUND Allogeneic hematopoietic cell transplantation is a potentially curative treatment for patients with acute lymphoblastic leukemia. However, the majority of older adults with acute lymphoblastic leukemia are not candidates for myeloablative conditioning regimens. A non-myeloablative preparative regimen is a reasonable treatment option for this group. We sought to determine the outcome ...

Cell colonization of synthetic polymers can be regulated by physical and chemical modifications of the polymer surface. High-density and low-density polyethylene (HDPE and LDPE) were therefore activated with Ar⁺ plasma and grafted with fibronectin (Fn) or bovine serum albumin (BSA). The water drop contact angle usually decreased on the plasma-treated samples, due to the formation of oxidized gr...

UNLABELLED : As clinical application of neural stem cell (NSC) grafting into the brain would also encompass aged people, critical evaluation of engraftment of NSC graft-derived cells in the aged hippocampus has significance. We examined the engraftment and differentiation of alkaline phosphatase-positive NSCs expanded from the postnatal subventricular zone (SVZ), 3 months after grafting into th...

Autologous fat is considered the ideal material for soft-tissue augmentation in plastic and reconstructive surgery. The primary drawback of autologous fat grafting is the high resorption rate. The isolation of mesenchymal stem cells from adipose tissue inevitably led to research focusing on the study of combined transplantation of autologous fat and adipose derived stem cells (ADSCs) and introd...

Cell grafting has been considered a therapeutic approach for Parkinson's disease (PD) since the 1980s. The classical motor symptoms of PD are caused by the loss of dopaminergic neurons in the substantia nigra pars compacta, leading to a decrement in dopamine release in the striatum. Consequently, the therapy of cell-transplantation for PD consists in grafting dopamine-producing cells directly i...

Ralstonia solanacearum is a causative agent of bacterial wilt and therefore poses serious threat to cultivated peppers (Capsicum annuum L.). Although attempts have been made control by grafting, the disease resistance mechanisms that protect grafted are poorly understood. Here, we grew composed rootstock Buyeding or Weishi scion Xinfeng 2. Following infection R. solanacearum, assessed differenc...

Parkinson disease is a neurological disorder accompanied by degeneration of dopaminergic system and neuronal loss. Recently studies have focused on stem cells therapy, therefore the goal of this study was to investigate the effect of adipose derived stem cells grafting, on locomotion and imbalance in Parkinson model of rats. Twenty-four male Wistar rats weighing 200-250 g were divided into thre...

Recent reports have suggested that very early excision (less than 24 hours post-burn) and primary closure of burn wounds might circumvent the immunosuppression which follows severe thermal trauma. The total body surface are (TBSA) involved in burn injuries of human subjects at risk for significant post-burn immunosuppression is large enough to require grafting. In the present study cell-mediate...

OBJECTIVE Early-stage oral or oropharyngeal carcinomas are often treated with surgical resection. Resulting wounds that are too large for primary closure can be covered with skin grafts or patches made from various biomaterials. Recently, polyglycolic acid sheets have been used for this purpose. METHODS We treated six patients with large wounds resulting from the resection of oral or orophary...
