Factors associated with a change in disposition for mental health patients boarding in an urban Paediatric emergency department.

Aim: Paediatric emergency departments (ED) nationwide experience a shared burden of boarding mental health patients. Whilst boarding, some patients have a change in disposition from hospitalization to discharge home. This phenomenon raises concern because EDs often have scarce resources for mental health patients.

Engineering Iron Responses in Mammalian Cells by Signal-Induced Protein Proximity.

A new synthetic biology engineering strategy integrating chemical reactivity sensing and small molecule induced protein dimerization has been developed to generate artificial Fe signaling circuitry to control tailored cellular events in mammalian cells. The dual function probe ABA-FE18 (Fe-sensing and protein dimerization) derived from ABA was developed and used to control gene activation, signal transduction, and cytoskeletal remodeling in response to Fe. This technology was utilized to design signal circuitry incorporating "AND" and "OR" biologic gates that enables mammalian cells to translate different combinations of Fe and HO signals into predefined biological outputs.
