Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

open access: yesCladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Updating the forelimb anatomy of the domestic cat (Felis catus, Felidae) based on evolutionary inferences of its muscles and nerves I: Shoulder and brachium

open access: yesJournal of Anatomy, EarlyView.
In this study, we provide a detailed description of the shoulder and brachium muscles and the brachial plexus of the domestic cat (Felis catus). We identified muscular variants (articularis humeri, coracobrachialis longus, biceps brachii caput breve), clarified the independence of the anconeus medialis muscle from the triceps brachii muscle, and ...

Functional Reconstruction of Temporomandibular Joint after Resection of Pigmented Villonodular Synovitis with Extension to Infratemporal Fossa and Skull Base: A Case Report

open access: yesThe Surgery Journal, 2016
Introduction Pigmented villonodular synovitis (PVNS) is a benign but aggressive lesion arising from sinovia. The temporomandibular joint (TMJ) is hardly ever involved.

Comparative histological analysis of vertebrates reveals Triassic climate variability across southern Pangea

open access: yesJournal of Anatomy, EarlyView.
Bone tissues of Triassic taxa reveal life history signals consistent with climatic variation across southern Pangea, spanning present‐day Brazil, Argentina, Zimbabwe, and India. Slower growth patterns within the Zimbabwean assemblage suggest a comparatively more arid intracontinental environment than those closer to the coast. Artwork by Andrey Atuchin.

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

open access: yesJournal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Three-Dimensional Assessment of Temporomandibular Joint Using MRI-CBCT Image Registration. [PDF]

open access: yesPLoS ONE, 2017
To introduce a new approach to reconstruct a 3D model of the TMJ using magnetic resonance imaging (MRI) and cone-beam computed tomography (CBCT) registered images, and to evaluate the intra-examiner reproducibility values of reconstructing the 3D models ...

Reconstructing the major skull myology of the giant stem‐amphibian Mastodonsaurus: A case study for early tetrapods

open access: yesJournal of Anatomy, EarlyView.
We reconstruct the major cranial musculature of the giant stem amphibian Mastodonsaurus giganteus, revealing a differentiated jaw‐adductor system, a probable sesamoid pulley, and previously unrecognised muscles. This EPB‐based case study establishes an anatomical framework for modelling feeding in early tetrapods and supports interpretations of ...

Cone-beam computed tomographic assessment of the inclination of the articular eminence in patients with temporomandibular disorders and chewing side preference

open access: yesBMC Oral Health, 2021
Background Chewing side preference (CSP) has been proposed as one etiology of temporomandibular disorders (TMDs) as it can induce the structural changes of the temporomandibular joint.

Myeloid A20 Regulates Periodontal Tissue Integrity and Temporomandibular Joint Structure

open access: yesJournal of Periodontal Research, EarlyView.
Dysregulation of A20 signaling has been implicated in several immune‐mediated diseases, including rheumatoid arthritis and psoriasis, conditions characterized by excessive NF‐κB activation and inflammatory tissue damage. The structural alterations observed in this model suggest that impaired regulation of innate immune signaling may increase ...
