Ritualized reflection in human dissection: Liminality, ethical negotiation, and professional identity formation among South Korean medical students

Anatomical Sciences Education, EarlyView.
Abstract Human dissection is a foundational component of medical education, yet it places students in profound ethical tension between scientific objectification and respect for human dignity. While prior studies have documented students' emotional responses, the structural transformation of their moral narratives over time, particularly within non ...

Lowering salivary pH with sugar‐containing gum augments salivary nitrite production and blood pressure reduction with dietary nitrate (beetroot juice)

British Journal of Clinical Pharmacology, EarlyView.
Acutely lowering salivary pH (with sugar‐containing acidic gum vs. sugar‐free gum) augments salivary nitrate reduction to nitrite, plasma nitrite concentration, and blood pressure lowering with dietary nitrate. Modifying salivary pH reveals a mechanism by which the nitrate‐nitrite‐NO pathway may be upregulated/inhibited, with potential for other ...
