PURPOSE We evaluated the concurrent and predictive validity of a novel robotic surgery simulator in a prospective, randomized study. MATERIALS AND METHODS A total of 24 robotic surgery trainees performed virtual reality exercises on the da Vinci® Skills Simulator using the da Vinci Si™ surgeon console. Baseline simulator performance was captured. Baseline live robotic performance on ex vivo a...

Background: As previous studies show, several effects of morphine are induced by the dopaminergic system. Sulpiride is a dopamine D2 receptor (DAD2) antagonist widely used in clinics to treat DArelated disorders. DAD2 receptors are abundant at hippocampal cornu ammonis (CA1). Objectives: This study aimed to investigate the possible interaction of morphine and sulpiride on DA synapses in CA1...

testing as a general trait of social life has received a great deal of attention by many language teachers and scholars. throughout history, people have been tested to prove their abilities and experiences or to confirm their capacities. many authorities have said that assessment and instruction should be integrated as a single and inseparable activity which seeks to understand development by a...

The present paper concentrates on a web-based inquiry in the synchronous computer-mediated communication (SCMC) via Web 2.0 technologies of Talk and Write and Skype. It investigates EFL learners’ socio-cognitive progress through dynamic assessment (DA), which follows Vygotsky’s inclination for supportive interchange in the zone of proximal development. Sixty adult EFL learners at upper-intermed...

Previous findings indicate that the basolateral amygdala (BLA) and the nucleus accumbens (NAc) interact in influencing memory consolidation. The current study investigated whether this interaction requires concurrent dopamine (DA) receptor activation in both brain regions. Unilateral, right-side cannulae were implanted into the BLA and the ipsilateral NAc shell or core in male Sprague-Dawley ra...

Abstract In Iran, most English teachers’ method of teaching writing is merely to have students do some writing exercises or simply to give them writing tests without any instruction, but writing is not an easy task for students, and teachers should be able to do more to facilitate their students’ writing. One of the ways to aid writing is dynamic assessment via graduated prompt. The graduated p...
