Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Loss, persistence and reversal of phenotypic traits

Biological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Three-Dimensional Tooth Model Reconstruction Using Statistical Randomization-Based Particle Swarm Optimization

, 2021
The registration between images is a crucial part of the 3-D tooth reconstruction model. In this paper, we introduce a registration method using our proposed statistical randomization-based particle swarm optimization (SR-PSO) algorithm with the ...

Digitally guided corticotomy using a customized surgical template (Suya corticotomy utility template): A technique report

Clinical Advances in Periodontics, EarlyView.
Abstract Background Precise control of corticotomy lines is critical in surgically facilitated orthodontic therapy. The Suya method is traditionally performed freehand, which introduces risks of root damage and procedural inconsistency. A digitally guided protocol may address these limitations by enhancing safety and technical predictability. Methods A

Reduction of gear pair transmission error with tooth profile modification

, 2008
The gear noise problem that widely occurs in power transmission systems is typically characterised by one or more high amplitude acoustic signals. The noise originates from the vibration of the gear pair system caused by transmission error excitation ...

Validation of an artificial tooth-periodontal ligament-bone complex for in-vitro orthodontic research

, 2015
Orthodontics research investigates the methods in which tooth displacement may be directed in the tooth-periodontal ligament-bone-complex. In the biological environment, the periodontal ligament is the soft tissue responsible for the absorption of forces

Volumetric analysis of root coverage with porcine acellular dermal matrix: Case study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Gingival recession is prevalent and often treated with coronally advanced flap plus connective tissue graft (CAF+CTG). Porcine acellular dermal matrix (PADM) offers a donor‐site‐free alternative. Contemporary digital imaging allows minimally invasive, three‐dimensional (3D) soft‐tissue assessment. This case report quantified 3D soft‐
