Although electrostatic catalysis can enhance the kinetics and selectivity of reactions to produce greener synthetic processes, the highly directional nature of electrostatic interactions has limited widespread application. In this study, the influence of oriented electric fields (OEF) on radical addition and atom abstraction reactions are systematically explored with ion-trap mass spectrometry using structurally diverse distonic radical ions that maintain spatially separated charge and radical moieties. When installed on rigid molecular scaffolds, charged functional groups lock the magnitude and orientation of the internal electric field with respect to the radical site, creating an OEF which tunes the reactivity across the set of gas-phase carbon-centred radical reactions.

Background: Rodent models have been widely used to investigate skin development, but do not account for significant differences in composition compared to human skin. On the other hand, two-dimensional and three-dimensional engineered skin models still lack the complex features of human skin such as appendages and pigmentation. Recently, hair follicle containing skin organoids (SKOs) with a stratified epidermis, and dermis layer have been generated as floating spheres from human-induced pluripotent stem cells (hiPSCs).

Differential recruitment drives pathogen-mediated competition between species in an amphibian chytridiomycosis system.

Ecol Appl

January 2025

Centre for Planetary Health and Food Security, and School of Environment and Science, Griffith University, Southport, Queensland, Australia.

Pathogens that infect multiple host species have an increased capacity to cause extinctions through parasite-mediated apparent competition. Given unprecedented and continuing losses of biodiversity due to Batrachochytrium dendrobatidis (Bd), the causative fungus of the amphibian skin disease chytridiomycosis, a robust understanding of the mechanisms driving cross-species infection dynamics is essential. Here, we used stage-structured, susceptible-infected compartmental models to explore drivers of Bd-mediated apparent competition between two sympatric amphibians, the critically endangered Litoria spenceri and the non-threatened Litoria lesueurii.

The COVID-19 pandemic had immediate impact on nursing students enrolled in postgraduate and post-registration nursing courses. Some students were required to undertake additional clinical hours and place their studies on hold, while others had clinical experiences and face-to-face classes suspended, with online learning modes quickly mobilized. While there have been many reports on the impact and experience of these changes on undergraduate students, limited reports have focused on challenges for nursing students who were registered for practice following completion of their undergraduate studies, and were enrolled in higher degree, postgraduate education programs.
