This study aims to explore the influence of hyaluronic acid (HA) on wound healing during xenogeneic porcine acellular dermal matrix (PADM) composite skin grafting. The results will facilitate the development of methods for improving graft contracture and poor elasticity of composite transplantation. Exogenous HA was added to composite PADM grafts and to thin autologous skin grafts during rabbit...

vessel for microanastomosis, non-microsurgical methods are suggested, such as a composite graft, retroauricular pocket, or a temporoparietal fascia flap. A few reports of large composite grafts to the ear have been published. The survival rate of composite grafts is lower than that of replantation with microvascular anastomosis. The vessel status of amputees who have sustained a human bite inju...

In the present paper, a novel superabsorbent hydrogel composite based on carrageenan have been prepared via graft copolymerization of acrylic acid (AA) in the presence of kaolin powder using methylenebisacrylamide (MBA) as a crosslinking agent and ammonium persulfate (APS) as an initiator. The certain variables of the graft copolymerization (i.e. the monomer, the initiator and the crosslinker c...

Because there is no 'ideal' method for the complete correction of some of the more complex congenital cardiac abnormalities, a technique of making a composite graft of autologous fascia lata has been developed. Three types of grafts are described, all of them being based on the same general principle. The composite graft comprises a conduit, which serves to enlarge or reconstruct the outflow tr...

context this study aimed to provide an overview of the literature on the radiopacity of dental materials in order to emphasize its importance. evidence acquisition english-language literature was investigated using manual and electronic searches for the terms “radiopacity,” “dental material,” “cement,” “composite,” “ceramic,” “endodontic root canal sealer,” “bone graft,” and “acrylic resin” in ...

BACKGROUND Composite aortic root replacement is accepted treatment for aneurysms of the ascending aorta involving the root with aortic valve regurgitation, but controversy continues regarding the best technique of operation. We excise the aneurysm, implant a composite valve graft, directly attach the coronary arteries to the aortic graft, and make the distal anastomosis to the divided aorta. ...

OBJECTIVE The aim of this study was to create a new injectable bone graft substitute by combining the features of calcium phosphate and bisphosphonate as a composite bone graft to support bone healing and to evaluate the effect of alendronate to the bone healing process in an animal model. MATERIAL AND METHOD In this study, 24 New Zealand white rabbits were randomly divided into two groups: a...

BACKGROUND In severe coronary artery disease, coronary artery bypass grafting (CABG) surgery is indicated to re-establish an adequate blood supply to the ischemic myocardium. Effectiveness of CABG surgery for symptom relief and mortality decrease should therefore depend on bypass graft patency. As bypass using a left internal mammary artery (LIMA)-to-left anterior descending coronary artery (LA...

The use of a composite graft with left internal thoracic artery (LITA) and arterial or saphenous vein (SV) grafts can allow the complete revascularization of the left coronary system (LCS) without cardiopulmonary bypass (CPB) and without ascending aorta manipulation (AAM), in order to reduce some complications in the immediate postoperative. This study shows 8-year angiographic follow-up result...

Autogenous bone is regarded as the gold standard for bone graft materials as it provides 3 elements necessary to generate and maintain bone: scaffolding for osteoconduction, growth factors for osteoinduction, and progenitor cells for osteogenesis. Allograft is more limited than autograft in these essential elements and yields more variable clinical results. Composite synthetic grafts offer an a...
