Experimental Extracorporeal Circulation System: A Pilot Study in Rats

Artificial Organs, EarlyView.
A miniature extracorporeal circulation (ECC) system was developed for reproducible rodent studies. This system incorporates an integrated heat exchanger and a silicone membrane oxygenator within a double‐lumen circuit, resulting in an ultralow priming volume of < 1.5 mL.

Frayed Rope and Resilient Threads: Fijian Healthcare and the COVID‐19 Pandemic

Asia Pacific Viewpoint, EarlyView.
ABSTRACT In April 2021, Fiji faced international scrutiny due to ‘horrific’ hospital conditions, including staff and patients lacking food, non‐operational operating theatres, and critical shortages of beds, medicine, and equipment. After successfully avoiding a major outbreak in 2020, a sudden surge in COVID‐19 cases in 2021 overwhelmed the public ...

A balance between stability and flexibility: Adaptive patterns of self‐regulated learning processes shape game‐based learning

British Journal of Educational Technology, EarlyView.
Abstract To ensure learning efficiency in game‐based learning (GBL), learners must regulate cognitive, affective, metacognitive and motivational (CAMM) processes, collectively known as self‐regulated learning (SRL). SRL is dynamic and non‐linear, characterized by regulatory patterns and CAMM interactions that lead to macro‐level SRL behaviours. In this
