Departing from standard practices: Strategic application of value engineering in the anatomy laboratory to enhance formaldehyde extraction using high‐impact, low‐cost, and low‐maintenance solutions

Anatomical Sciences Education, Volume 18, Issue 3, Page 241-253, March 2025.
Abstract This study describes the process of developing a high‐impact, low‐cost, and low‐maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection ...

Body donor programs in Australia and New Zealand: Current status and future opportunities

Anatomical Sciences Education, Volume 18, Issue 3, Page 301-328, March 2025.
Abstract Body donation is critical to anatomy study in Australia and New Zealand. Annually, more than 10,000 students, anatomists, researchers, and clinicians access tissue donated by local consented donors through university‐based body donation programs. However, little research has been published about their operations.

Cooperative learning in anatomy: Comparing virtual avatars and human specimens

Anatomical Sciences Education, EarlyView.
Abstract Contemporary research demonstrated that undergraduate medical students rated an augmented reality learning tool entitled “human muscular arm avatar” as useful for their self‐directed individual learning. Beyond this subjective assessment, it was largely unknown whether avatar‐based study would also improve knowledge test scores at an objective

Neurofilament light chain as in vitro and clinical biomarker of vincristine‐induced peripheral neuropathy

British Journal of Clinical Pharmacology, EarlyView.
Aims Vincristine‐induced peripheral neuropathy (VIPN) is a common side effect in children and adolescents treated with vincristine. Assessing VIPN, especially in young children, is challenging due to a lack of sensitive tools. This limits our understanding of the nature and risk factors of VIPN. This study aimed to investigate neurofilament light chain
