considering the importance of grafted seedlings for the development of pecan orchards in subtropical regions of iran, and in order to achieve a scientifically practical method of producing grafted pecan seedlings, this project was carried out in safiabad agricultural research center of dezful during 2011-12. the project investigated three grafting methods including hot cable, hypocotyl and late...

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...

RATIONALE The complication of iatrogenic distraction of odontoid fracture after anterior screw fixation has not been reported in the literature. We treated the patient with endoscopically assisted bone grafting with good results. The new technique was not reported in the management of odontoid fracture or nonunion before. PATIENT CONCERNS A 22-year-old man presented with neck pain after a mot...

Received April 2008 Accepted November 2008 INTRODUCTION Short or damaged renal vessels represent a serious challenge during kidney transplantation. The increasing risk of thrombosis, bleeding, or compromised kidney function often leads to declining the donated kidneys with damaged vessels.(1) We here describe 5 kidney transplantations in which a polytetrafluoroethylene (PTFE) vascular graft was...

BACKGROUND The aim of the study was to investigate the in vivo efficacy of local and systemic antibiotic prophylaxis in the prevention of Staphylococcus (S.) epidermidis graft infection in a rat model and to evaluate the bacterial adherence to frequently used prosthetic graft materials. METHODS Graft infections were established in the subcutaneous tissue of 120 male Wistar rats by implantatio...

Plant grafting is a biologically important phenomenon involving the physical joining of two plants to generate a chimeric organism. It is widely practiced in horticulture and used in science to study the long-distance movement of molecules. Despite its widespread use, the mechanism of graft formation and vascular reconnection is not well understood. Here, we study the dynamics and mechanisms of...

indian ber (ziziphus mauritiana) has growing type as grape and is inclined to horizental and down ward growth. if it is not trained appropriately, it would grow into very bushy with thiny shoots. hence, such trees have short lives, and are liable to pests and diseases with low yield. fruit harvesting is also difficult in bushy trees. therefore, proper pruning and training of young trees is esse...

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...

Current animal models for the evaluation of synthetic grafts are lacking many of the molecular tools and transgenic studies available to other branches of biology. A mouse model of vascular grafting would allow for the study of molecular mechanisms of graft failure, including in the context of clinically relevant disease states. In this study, we comprehensively characterise a sutureless grafti...

BACKGROUND Autologous fat grafting evolved over the twentieth century to become a quick, safe, and reliable method for restoring volume. However, autologous fat grafts have some problems including uncertain viability of the grafted fat and a low rate of graft survival. To overcome the problems associated with autologous fat grafts, we used uncultured adipose tissue-derived stromal cell (stromal...
