Simulation-based Assessment to Reliably Identify Key Resident Performance Attributes.

Background: Obtaining reliable and valid information on resident performance is critical to patient safety and training program improvement. The goals were to characterize important anesthesia resident performance gaps that are not typically evaluated, and to further validate scores from a multiscenario simulation-based assessment.

Methods: Seven high-fidelity scenarios reflecting core anesthesiology skills were administered to 51 first-year residents (CA-1s) and 16 third-year residents (CA-3s) from three residency programs.

The effect of head rotation on efficiency of face mask ventilation in anaesthetised apnoeic adults: A randomised, crossover study.

Background: Upper airway obstruction occurs commonly after induction of general anaesthesia. It is the major cause of difficult mask ventilation.

Objectives: The aim of this study was to determine whether head rotation improves the efficiency of mask ventilation of anaesthetised apnoeic adults.

RAB2A: a major subacrosomal protein of bovine spermatozoa implicated in acrosomal biogenesis.

The perinuclear theca (PT) of mammalian sperm is a unique subcellular structure encapsulating the nucleus. Compositionally, the PT is made up of at least six prominent polypeptides (60, 36, 31, 28, 24, and 15 kDa), of which only two have been sequence identified, as well as many less prominent ones. As an ongoing process in unveiling the protein composition of the PT, we have uncovered the sequence identity of the prominent 24-kDa polypeptide (PT24).
