Enforced expression of Simian virus 40 large T-antigen leads to testicular germ cell tumors in zebrafish.

Testicular germ cell tumors (TGCTs) are the most common malignancy in young men. However, there are few in vivo animal models that have been developed to study this disease. We have used the pufferfish (fugu) lymphocyte-specific protein tyrosine kinase (flck) promoter, which has been shown to enforce high-level expression in the testes of transgenic mice, to express Simian virus 40 large T-antigen in zebrafish testes.

Evaluation of multidisciplinary simulation training on clinical performance and team behavior during tracheal intubation procedures in a pediatric intensive care unit.

Objective: Tracheal intubation in the pediatric intensive care unit is often performed in emergency situations with high risks. Simulation has been recognized as an effective methodology to train both technical and teamwork skills. Our objectives were to develop a feasible tool to evaluate team performance during tracheal intubation in the pediatric intensive care unit and to apply the tool in the clinical setting to determine whether multidisciplinary teams with a higher number of simulation-trained providers exhibit more proficient performance.
