in this paper, grafting of acrylic acid monomer on gum tragacanth was performed. variable of experiment included concentration of initiators and monomer, time, and temperature. grafting efficiency was measured in the term of percentage of grafting (%g) and percentage of grafting efficiency (%e). effectiveness of grafted gum in ferrous ion removal at different condition was assessed. according t...

BACKGROUND In recent years the therapeutic application of extracted adipose tissue for autologous fat grafting and the application of adipose tissue-derived mesenchymal stem cells (adMSC) isolated thereof has progressed. Water-jet assisted liposuction (WAL) is 1 procedure for harvesting adipose tissue and provides a favorable aesthetic outcome combined with high tissue protection. Tissue aspira...

Vacuum freeze-dried blood is a good material for vascular grafts. However, studies on this technology are few, particularly on physical performance change of freeze-dried blood vessel at different pre-freezing rate. In our study, pig aortas were non-invasively scanned by micro-CT in each stage of freeze-drying at different pre-freezing rates, then comparing the porosity ratio and grey level und...

A multi-center retrospective review of major prosthetic graft infection outcomes was undertaken to determine graft preservation and limb salvage rates. The management of infected prosthetic vascular grafts continues to be controversial. The purpose of this study was to review the surgical management of major extracavitary prosthetic vascular graft infections and to correlate the outcomes on the...

OBJECTIVES To investigate whether patency of a thin walled 8 mm fluoropassivated Dacron graft was similar to that of a standard 8mm PTFE graft for femorofemoral crossover bypass surgery. DESIGN A randomised multicentre clinical trial comparing two vascular grafts with participation of 10 departments of vascular surgery in Denmark, Sweden and Norway. PATIENTS AND METHODS 198 patients were ra...

Porogen leaching is a widely used and simple technique for the creation of porous scaffolds in tissue engineering. Sodium chloride (NaCl) is the most commonly used porogen, but the current grinding and sieving methods generate salt particles with huge size variations and cannot generate porogens in the submicron size range. We have developed a facile method based on the principles of crystalliz...

Episodes of septic arthritis caused by Pseudomonas aeruginosa occurred in a patient with an infected vascular graft. He responded well to antibiotic therapy and removal of the graft was not required. The aetiology of this unusual cause of septic arthritis is discussed.

The efficacy of linezolid and temporin A in the prevention of prosthetic graft infection due to methicillin-resistant Staphylococcus epidermidis with intermediate resistance to glycopeptides was investigated in a subcutaneous rat pouch model. Linezolid and temporin A, alone or combined, greatly reduced the bacterial numbers compared to the effect with control drugs.

In the past decade, the face of surgical coronary revascularization has been changed by a number of advances, most notably the development of minimally invasive techniques, including minimally invasive direct coronary artery bypass (MIDCAB), off-pump coronary artery bypass (OPCAB), and totally endoscopic, robot-assisted coronary artery bypass grafting (TECAB). Initial attempts to perform cardia...
