This paper contributes the discussion about applying DeLone & McLean success model. Since its introduction in 1992, the model has been widely used and evaluated. In this paper the model is used as a descriptive tool in evaluating a virtual learning environment. The study relies on prior research and does not question the measures. Instead, the model contributes the evaluation and describes the ...

INTRODUCTION This study reports the technical and mid-term clinical results of the second-generation Anaconda AAA Stent Graft System endovascular device for treatment of abdominal aortic aneurysm (AAA). The design of the Anaconda AAA Stent Graft System is characterised by a three-piece system consisting of two proximal independent saddle-shaped nitinol self-expandable rings with hooks fixation,...

Mouse models have several advantages in transplantation research, including easy handling, a variety of genetically well-defined strains, and the availability of the widest range of molecular probes and reagents to perform in vivo as well as in vitro studies. Based on our experience with various murine transplantation models, we developed a heterotopic pancreas transplantation model in mice wit...

BACKGROUND The success of fat grafting in breast reconstruction depends on fat retention. The use of stem-cells-enriched fat graft is an alternative method for graft stability. CASE REPORT A case of nipple-areola sparing mastectomy double stage reconstruction with the use of stem cells enhanced fat graft is reported. CONCLUSIONS Fat grafting is growing as a new and promising tool in reconst...

As the success ofa grafting operation ultimately depends upon the transparency of the graft, the problem of opacification is of great interest and practical importance to the ophthalmic surgeon. This paper is the result of the study of some fifty personal cases in an attempt to elucidate certain aspects of the problem as it occurs in perforating corneal grafts. A graft may become opaque for one...
