A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

open access: yesCladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Structure and Tooth Profile Analysis of the Two-tooth-difference Oscillating-disc Movable Teeth Transmission

open access: yes工程科学与技术, 2017
:As an axially movable teeth transmission,oscillating-disc movable teeth transmission has the advantage of small radial dimension, but its application is limited by complicated structure and unbalanced load and force-coupling.In this paper,the ...

Chromatin Remodeller BRD9 Orchestrates Odontoblastic Differentiation via Coordinating RUNX2‐KLF4

open access: yesCell Proliferation, EarlyView.
During odontoblast lineage commitment, the chromatin remodeller BRD9 acts as a critical epigenetic coordinator, orchestrating the chromatin landscape to facilitate synergistic binding of key transcription factors RUNX2 and KLF4 to target loci for odontogenesis.

Magnesium Enhances Immune Clearance of P. gingivalis in Macrophages by Suppressing MCU‐Mediated Mitochondrial Calcium Overload

open access: yesCell Proliferation, EarlyView.
Magnesium restores macrophage clearance of P. gingivalis by inhibiting MCU‐mediated calcium overload. P. gingivalis is mainly phagocytosed by macrophages but escapes intracellular clearance via MCU‐mediated mitochondrial and cytosolic Ca2+ overload in periodontitis. The persistent P.

Artificial intelligence for detection and segmentation of accessory root canals in endodontic imaging: A systematic review

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract Accessory root canal anatomy, including second mesiobuccal (MB2) and middle mesial canals (MMC), is difficult to identify and may compromise endodontic outcomes when missed, supporting artificial intelligence (AI)‐based diagnostic tools. This systematic review (CRD420261415943) included studies evaluating AI models for accessory canal or root ...

Effects of organic solvents on the depth‐of‐cure determination of conventional and bulk‐fill resin composites

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study investigated the influence of organic solvents on the depth of cure (DOC) of resin composites. Two conventional (Filtek Universal [FU] and Beautifil II [BE]) and two bulk‐fill (Filtek One Bulk Fill [FO] and Beautifil‐Bulk [BB]) composites were evaluated.
