BACKGROUND Conventional single-incision laparoscopic surgery has been successfully employed for treatment of ovarian endometriomas. However, this technique presents surgeons with formidable ergonomic challenges, that make its widespread adoption unlikely. Robotic assistance in single-incision laparoscopic surgery provides adequate instrument triangulation through a single fulcrum, while elimina...
teachers beliefs have usually been left unattended in the realm of educational research in iranian context. one of those beliefs which seems to impact teachers performance in the classroom is their sense of self-efficacy, which refers to teachers belief in their ability to enhance student achievement and in bringing about positive learning outcomes. the present study aimed to investigate the pr...
The Mu transposons of the Robertsons's Mutator transposable element system in maize are unusual in many respects, when compared to the other known plant transposon systems. The excision of these elements occurs late in somatic tissues and very rarely in the germ line. Unlike the other plant transposons, there is no experimental evidence directly linking Mu element excision and integration. We h...

Background: There are different treatment options with variable results for the management of pyogenic granuloma (PG). The aim of this study was to evaluate and compare the cosmetic results and recurrence rate of classic surgical excision with a novel proposed method, curettage and punch excision of the vascular stalk (C&P;) ...
In this paper we introduce a word-based stream cipher consisting of a chaotic part operating as a chaotic permutation and a linear part, both of which designed on a finite field. We will show that this system can operate in both synchronized and self-synchronized modes. More specifically, we show that in the self-synchronized mode the stream cipher has a receiver operating as an unknown input o...
Objectives Our laboratory is developing a surgical robotic system to further improve dexterity and visualization that will allow for broader application of transnasal skull base surgery. To optimize this system, intraoperative force data are required. Using a modified curette, force data were recorded and analyzed during pituitary tumor excision. Design A neurosurgical curette was modified by t...
