Disease of South American camelids in England and Wales: Analysis of diagnoses from Animal and Plant Health Agency laboratory submissions between 2012 and 2021

Veterinary Record, EarlyView.
Abstract Background South American camelids (SACs) have become increasingly popular in the UK. Consequently, knowledge among veterinary practitioners about diseases in these non‐native species has improved, although gaps remain. The remit of this study was to identify common diseases of SACs based on Animal and Plant Health Agency (APHA) surveillance ...

Quantitative collagen and proteoglycan imaging reveal organic layering, gradients and regional texture in young mature dental cementum

VIEW, EarlyView.
Cementum, the mineralized tissue covering all mammalian tooth roots, helps maintain tooth stability, but its internal organization is still poorly understood. In this study, we combine quantitative histologial methods to map the regional distributions of collagen fibers and proteoglycan‐rich matrix layers in porcine cementum.

Use of Cone Beam Computed Tomography to Identify the Morphology of Maxillary and Mandibular Premolars in Chennai Population

Brazilian Dental Science, 2019
Objective: The complex root canal anatomy is inherently colonised by microbial flora. Endodontic treatment success is always related to adequate disinfection of the root canal space, which ultimately affects the treatment outcome.

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer

Wildlife Biology, EarlyView.
Accurate age determination in roe deer Capreolus capreolus is essential for selective harvesting and informed population management, yet field‐based methods widely used by hunters remain imprecise. This study compared field‐based and laboratory age determination methods in 204 harvested roe deer, categorized by sex and habitat type (forest versus open ...

Reassessment of the morphological evidence for hominin hybrids in the Levant Réévaluation des indices morphologiques d'hominines hybrides au Proche‐Orient

Journal of the Royal Anthropological Institute, EarlyView.
The Levantine hominin fossil and archaeological records have played a central role in long‐standing palaeoanthropological debates over origin models and possible interbreeding between Neanderthals (Homo neanderthalensis) and Homo sapiens. Recent research has provided a strong framework for the morphological expectations of recent hybrid ancestry in ...

A New Model of Feeding Biomechanics Based on Tied‐Arch Principles

Integrative Zoology, EarlyView.
This new biomechanical model explains the major stress and strain patterns generated through the cranium during biting. The model proposes that the cranium resolves bite‐induced reaction forces through arcs of compressive stress that span the cranial structure between biting teeth and both jaw joints.

Evaluation of the Adequate Radiopacity of Cavity Lining/Base and Core Build‐Up Light Cured Composite Resins

Australian Dental Journal, EarlyView.
ABSTRACT Background This study aimed to compare the radiopacity of composite resins (CR) used as lining, base, and core‐build up materials with enamel and dentine and evaluate their compliance with ISO 4049. Methods Specimens of 1, 2, and 3 mm thicknesses; (n = 6) were fabricated from 13 low‐viscosity and 10 regular‐viscosity CRs.
