Early Pliocene Varanus (Squamata, Varanidae) remains from Megalo Emvolon, Thessaloniki, Greece

The Anatomical Record, EarlyView.
The article describes new cranial and postcranial varanid material from Megalo Emvolon Lower Pliocene vertebrate fossil site near Thessaloniki. The fossils, likely representing a single individual, are referred to Varanus cf. marathonensis. Abstract This study describes new fossil varanid material from a recently discovered fossil spot (MVL site) at ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

The Anatomical Record, EarlyView.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils

The Anatomical Record, EarlyView.
Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Beyond the Curve: The Muscle-Specific Asymmetries of Adolescent Idiopathic Scoliosis. [PDF]

JOR Spine
Asymmetries in paraspinal muscle volume, intramuscular fat, and fat‐free muscle, observed across 11 vertebral levels, were greater in Adolescents with Idiopathic Scoliois (AIS) than in typically developing controls. Muscle asymmetries follow the shape of the scoliotic curve, typically with greater muscle volumes and intramuscular fat on the concave ...

Late‐Onset Spondylarthritis Presenting as Glucocorticoid‐Resistant Polymyalgia Rheumatica: A hitherto underappreciated entity where TNF or IL‐17 Blockade may have a Therapeutic Role

Arthritis &Rheumatology, Accepted Article.
Background Polymyalgia rheumatica (PMR) is an age‐related inflammatory disease with shoulder‐hip girdle involvement. Magnetic resonance imaging (MRI) reveals extracapsular/entheseal soft tissue involvements in both PMR and spondyloarthritis (SpA) with sacroiliac joint and peri‐entheseal spinal bone marrow oedema (BMO) being characteristic of SpA ...

The Development of the Human Female Reproductive Tract. Part 1: Uterine Tube and Uterus

Clinical Anatomy, EarlyView.
ABSTRACT The uterine tubes and uterus develop from the paramesonephric (Müllerian) ducts. Most experimental data are obtained in rodents. Since the (micro‐)anatomy of the murine urogenital tract differs from that in humans, evaluation of the translatability of mouse data to human development is relevant.
