Ordered assembly of Cas12a for better performance of CRISPR/Cas system with application to the diagnosis of dental caries

open access: yesInterdisciplinary Medicine, EarlyView.
Here, we present a tetrahedral DNA framework (TDF)‐mediated Cas12a ordered assembly strategy. TDFs arrange CRISPR/Cas12a into ordered structures controllably, enhancing catalytic efficiency through localized Cas12a hotspots while maintaining spatial intervals to facilitate substrate diffusion.

A Framework to Establish Diet and Nutrition Competencies for Oral Health Care Education

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Objective: To prevent and manage oral disease, oral health care practitioners (OHCPs) must provide dietary counseling based on nutrition science. OHCPs are often ill‐equipped to provide such counseling due to fragmented and inadequate dietary education, which is typically attributed to limited curricular time or appropriately qualified faculty.

Macroscopic, Histological and Ultrastructural Features of the Tongue of the Anatolian Wild Boar (Sus scrofa libycus)

open access: yesMicroscopy Research and Technique, EarlyView.
Integrated macroscopic, histological, and ultrastructural analyses revealed five distinct lingual papillae types (filiform, fungiform, conical, foliate, and vallate) in the Anatolian wild boar (Sus scrofa libycus). Mechanical papillae showed marked structural specialization, while gustatory papillae exhibited region‐specific distribution of taste buds.
