Exploring Gas Evolution Oscillators: Mechanisms and Applications.

We review an iconic class of chemical oscillators driven by phase transition instabilities, namely Gas Evolution Oscillators (GEOs). These systems show oscillatory dynamics in the delivery of gas sustained simple reactions yielding gaseous products in a liquid mixture, due to nucleation and supersaturation phenomena. After presenting the main features and properties of these systems, we deepen the underlying mechanism through a unified picture of the various models that have been proposed to describe this kind of oscillations.

Development of a Prioritized Anesthesiology Residency Critical Care Content Outline.

Background: Critical care education is an important, mandatory component of residency training in anesthesiology. Currently, there is no accepted national standardized curriculum, and a prioritized critical care content outline would be beneficial to the creation of a pragmatic standardized residency curriculum. The modified Delphi method is a recognized method for establishing consensus in medical education.

Consensus-Derived Recommended Skills for Transition to Residency Courses.

Purpose: Transition to residency (TTR) courses facilitate the medical student-residency transition and are an integral part of senior medical student training. The authors established a common set of skills for TTR courses, and an expected level of entrustment students should demonstrate in each skill on TTR course completion.

Method: A modified Delphi approach was used with 3 survey iterations between 2020 and 2022 to establish skills to be included in a TTR course.

Specific anion effects on urease activity: A Hofmeister study.

The effects of a range of electrolytes on the hydrolysis of urea by the enzyme urease is explored. The autocatalytic behavior of urease in unbuffered solutions and its pH clock reactions are studied. The concentration dependence of the experimental variables is analyzed in terms of specific ion-enzyme interactions and hydration.

Transition to Residency Courses: Recommendations for Creation and Implementation.

Transition to Residency (TTR) courses help ease the critical transition from medical school to residency, yet there is little guidance for developing and running these courses. In this perspective, the authors use their expertise as well as a review of the literature to provide guidance and review possible solutions to challenges unique to these courses. TTR courses should be specialty-specific, allow for flexibility, and utilize active learning techniques.
