An Evaluation of the Use of Low-Fidelity and High-Fidelity Mannequins in Clinical Simulations in a Module Preparing Final Year Children's and General Nursing Students for Internship Placement.

Internationally, the use of simulation-learning environments in nursing education has escalated over the last number of years. Simulations have been recognized as providing clinical opportunities for student nurses to gain experience in a safe and controlled learning environment. A module specifically preparing fourth year children's and general nursing students for internship was developed.

What is the impact of video as a teaching method on achieving psychomotor skills in nursing? A systematic review and meta-analysis.

Objectives: The aim of this systematic review (SR) is to establish if video is a beneficial teaching method when teaching psychomotor skills in nursing.

Design: Systematic review.

Data Sources: A database search of CINAHL, MEDLINE, EMBASE and Cochrane was performed with search terms 'video', 'nurse' 'RCT' and 'practical skills' resulting in seventy-four research articles.

Beta2-adrenoceptor-mediated prejunctional facilitation and postjunctional inhibition of sympathetic neuroeffector transmission in the guinea pig vas deferens.

This study examines the role of prejunctional and postjunctional beta-adrenoceptors in the modulation of sympathetic cotransmission in the guinea pig vas deferens. The prejunctional involvement of beta-adrenoceptors was evaluated by testing the effects of several agonists and antagonists on the nerve stimulation-evoked overflow of ATP and norepinephrine (NE) from the "in vitro" vas deferens. The nonsubtype-selective beta-adrenoceptor agonist isoproterenol and the beta2-subtype-selective agonist clenbuterol increased, to a similar degree, the overflow of ATP and NE, while the beta1-subtype-selective agonist xamoterol and the beta3-subtype-selective agonist BRL 37 344 had no effect.
