Mammalian Osteoderm Ultrastructure in the Armored Acomys Spiny Mouse Tail

open access: yesSmall, EarlyView.
The ultrastructure of armored platelets – termed osteoderms – in the tail skin of Acomys cahirinus spiny mice is characterized using 2D and 3D microscopy methods. The imbricated structure is composed of calcium phosphate biomineral and has select structural elements that are bone‐like and tooth‐like in nature.

Risk factors for dental overgrowth in rabbits: A retrospective study using electronic health records

open access: yesVeterinary Record, EarlyView.
Abstract Background Rabbits’ teeth grow continuously. Overgrown teeth are a frequent cause for veterinary consultation and can have severe welfare implications. The risk factors for overgrown teeth are incompletely understood. Methods Rabbits with overgrown teeth recorded in their electronic health records (EHRs) were identified from a large population

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

open access: yesVIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Analysis of the Internal Anatomy of Distal Root Canals of Mandibular Molars: A Micro‐Computed Tomography Study

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Detailed knowledge of the internal anatomy of the root canal system and its variations is essential for selecting appropriate endodontic treatment protocols. Micro‐computed tomography (micro‐CT) allows for nondestructive, high‐resolution three‐dimensional (3D) analysis of extracted teeth, enabling precise evaluation of root canal morphology ...

Tooth root strength of worm gear shafts with concave and convex tooth profiles

open access: yes
The load-bearing capacity of industrial worm gearboxes is primarily limited by failure of the worm wheel due to the soft bronze material. While worm gear boxes with higher strength wheel materials like cast iron or steel are most used in low-speed ...
