Delayed graft function in renal transplantation : aetiology and impact on graft outcome
… significant complications. The most common allograft complication post transplantation is the development of delayed graft function with a reported incidence of between 23 to 34%. This is a costly complication requiring ongoing dialysis and prolonged hospitalization. It also has a significant …

The management of corneal graft rejection
… of superficial keratectomy. The idea of corneal grafting was suggested relatively recently3,4• Guillaume Pellier de 22 Quengsy5, a Frenchman, suggested in 1789 the complete replacement of the opaque cornea using a thin glass disc the size of the cornea and set in a silver rim. He suggested that …

Graft polymerisation of antioxidants into natural rubber
… relaxation. The curing characteristics of the grafted rubber samples were studied in detai1 using the Monsanto rheometer. It was found that antioxidants which do not contain vinyl groups also react under the same conditions with natural rubber latex. Some of these appeared to be marginally more …

Regioselective Design of Polysaccharide Ester Graft Copolymers
Polysaccharide graft (co)polymers, where a polysaccharide comprises the backbone and a separate (co)polymer comprises grafted side chains, are growing in popularity as blend compatibilizers, sustainable elastomers, self-assembling materials, and drug delivery components. This popularity is …

NOVEL NANOFIBER-BASED GRAFT FOR HEART VALVE REPLACEMENT
Creating a functional heart valve graft that lasts a lifetime is one of the main targets of cardiovascular tissue engineering. While processed conventional collagen-based heart valves have been used for many years, they eventually fail because of inadequate cell infiltration and insufficient …

THE ROLE OF DENDRITIC CELLS IN GRAFT REJECTION
… So far the acceptance of a mismatched graft is achieved through immunosuppression that requires long-term treatment and a variety of methods have been explored to prevent rejection and achieve transplant tolerance in mouse models. There are several factors that contribute to acquired …

Composite hydrogel-nanofibre vessels for vascular graft applications
A vascular graft should mimic the structure and properties of the native artery which has a layered structure. The media layer of native arteries contributes the main mechanical support to the vessel and the intima layer, lined with endothelial cells, provides a smooth antithrombogenic surface for …

Nitric Oxide Releasing Polymers For Vascular Graft Applications
… utilization of the system towards vascular graft application was also studied. The idea behind this NO-based therapy was to provide a material that will not only mimic native blood vessels, but would also enable endothelial cell [EC] proliferation, promoted by long-term NO release …

Development and investigation of polymeric vascular graft materials
… ischemia is often treated using bypass grafts. Although autologous material, the preferred source for constructing a bypass graft, often provides a graft with satisfactory patency rates, it is not always available and suitable for use. In these cases synthetic material is often utilised …

Modification of a microbial co-polyester by graft copolymerisation
… to lower the thermal softening temperature by grafting chains of poly(methyl acrylate), (which softened at the required temperature) to the microbial polyester backbone selected for this work was poly(3-hydroxybutyrate-co-3- hydroxyvalerate)(,P HV). PHV is very stable chemically and of the …

Coaxially electrospun heparin-eluting scaffolds for vascular graft application
… scaffolds for small diameter vascular grafts (< 6 mm) has shown promise in the search for alternative solutions, as current synthetic grafts have high failure rates. The inclusion of heparin into such scaffolds can be beneficial for vascular graft applications as it could prevent …

Functional Capacity Outcomes following Coronary Artery Bypass Graft Surgery
The objective of this study was to determine if this is possible to predict 3 mo post-CABG treadmill VO2pk outcomes from a combination of pre-surgical physical fitness and health and clinical status variables. To determine the VO2pk, subjects performed a maximal treadmill test using a ramp protocol …
