An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

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 ...

Integrating whole‐bone and regional analyses to understand human scapular growth

open access: yesThe Anatomical Record, EarlyView.
Abstract This study investigates ontogenetic changes in human scapular morphology using three‐dimensional geometric morphometrics with whole‐bone and region‐specific analyses. The aim is to evaluate whether the scapula follows a regular developmental pattern and whether its functionally distinct components, the scapular spine (SS) and glenoid fossa ...

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.

The lower deciduous dentition of protodidelphids (Mammalia, Marsupialia) from the Itaboraí Basin (lower Eocene), Brazil, and the validity of “Riolestes capricornicus” (Goin et al., 2009)

open access: yesThe Anatomical Record, EarlyView.
Abstract The Itaboraí Basin, Southeastern Brazil, preserved one of the most diverse mammalian faunas from the Paleogene, with Metatheria comprising more than 60% of its diversity. Among identified metatherian clades, it has been argued that Paucituberculata is represented by “Riolestes capricornicus”.

Computed Tomography‐Based Morphometric Analysis Reveals Intercondylar Notch Stenosis and Osteophytes Are Associated With Anterior Cruciate Ligament Injury

open access: yesArthroscopy, EarlyView.
Purpose To quantitatively assess intercondylar notch morphometrics using 3‐dimensional computed tomography reconstruction, evaluate their association with anterior cruciate ligament (ACL) injury in Asian populations, and investigate the prevalence of osteophytes in patients with ACL injury.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

open access: yesAnimal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Comparative Analysis of Salmonella typhimurium‐Induced Transcriptomic Changes in the Spleen of Beijing‐You Chickens and Guang Ming Broilers

open access: yesAnimal Research and One Health, EarlyView.
This study analyzed the spleen transcriptomes of different chicken breeds, identified key differentially expressed genes (EGR1, FOS, and DUSP1) that regulate resistance to Salmonella infection, and elucidated the underlying regulatory mechanisms, thereby providing new targets for disease‐resistant breeding in poultry.

Dual Labral and Ligamentum Teres Reconstruction Achieves High Functional Outcomes and Arthroplasty‐Free Survivorship at 2 Years

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate the clinical outcomes and survivorship of hip arthroscopy with simultaneous labral and ligamentum teres (LT) reconstruction for the treatment of irreparable labral and LT tears, with a minimum follow‐up of 2 years. Methods Prospectively collected data were retrospectively reviewed for patients who underwent combined arthroscopic ...

A Narrow Medial Femoral Condyle Width Is Associated With Anteromedial Rotatory Instability After Anterior Cruciate Ligament Injury

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To identify bone morphological risk factors and injury patterns of medial structural injuries in patients with anteromedial rotatory instability (AMRI) after anterior cruciate ligament (ACL) injury. Methods This comparative study analyzed patients’ data between August 2024 and June 2025.
