Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

open access: yesThe Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

open access: yesThe Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Improved Detection of Myositis‐Specific Autoantibodies Using Luciferase Immunoprecipitation Systems Assay: Comparison With Line Blot and Conventional Immunoprecipitation

open access: yesArthritis &Rheumatology, EarlyView.
Objective Myositis‐specific autoantibodies guide the diagnosis and classification of idiopathic inflammatory myopathies, but current immunoassays vary in accuracy, particularly for autoantibodies associated with interstitial lung disease. To compare the performance of the luciferase immunoprecipitation systems (LIPS) assay with line blot and ...

Effective Performance of the 2022 American College of Rheumatology/EULAR Classification Criteria for Antineutrophil Cytoplasmic Antibody–Associated Vasculitis in Pediatric Patients: An ARChiVe Study

open access: yesArthritis &Rheumatology, EarlyView.
Objective To assess the 2022 American College of Rheumatology (ACR)/EULAR classification criteria for antineutrophil cytoplasmic antibody–associated vasculitis (AAV) in children with chronic small‐to‐medium vessel vasculitis. Methods A cohort of 574 patients, identified by physician's diagnosis (MD‐diagnosis) in A Registry of Childhood Vasculitis, was ...

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

open access: yesArthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

Human Fibroblast–Myeloid Cell Tissue Atlas Across the Lungs, Synovium, Skin, and Heart

open access: yesArthritis &Rheumatology, EarlyView.
Objective The availability of single‐cell RNA sequencing (scRNAseq) data in different tissues and disease states provides an opportunity to compare cellular subsets and identify common and unique cellular activation. In this study, we aimed to characterize shared and tissue‐specific myeloid and stromal phenotypes and to uncover key cellular subtypes ...

Comparative Transcriptional Profiling of Key Macrophage and Fibroblast Subpopulations in Rheumatoid Arthritis–Associated Lung Disease

open access: yesArthritis &Rheumatology, EarlyView.
Objective Rheumatoid arthritis (RA) often involves extra‐articular complications, including interstitial lung disease (ILD) and/or pulmonary nodules. Transcriptomic profiling of lung tissue provides the opportunity to directly assess cell‐specific gene expression and corresponding pathway activation in different types of rheumatoid lung disease ...
