Refinements for embryo implantation surgery in the mouse: comparison of injectable and inhalant anesthesias - tribromoethanol, ketamine and isoflurane - on pregnancy and pup survival.

An essential aspect of genetically-engineered mice (GEM) is the ability to produce live animals after the appropriate injection procedure. Animals are produced by implantation of manipulated embryos into pseudopregnant females for gestation, parturition, and growth to the weaning stage. This study was carried out to test whether the anesthesia used during surgery could affect the number of pups produced.

Assessing radiologist assistant supervision levels in Florida.

Background: As radiologist assistants (RAs) become more prevalent in the radiology work force, it is important to re-evaluate how they practice and are supervised.

Purpose: To analyze the impact of RA supervision levels on clinical practice.

Methods: A survey was conducted to evaluate whether a random sample of radiologists in Florida would recommend changes to the current levels of supervision required for advanced-practice technologists.
