New role of calcium‐binding fluorescent dye alizarin complexone in detecting permeability from articular cartilage to subchondral bone

open access: yesFASEB BioAdvances
Osteoarthritis (OA) is a chronic degenerative joint disorder characterized by the progressive deterioration of articular cartilage and concomitant alterations in subchondral bone architecture. However, the precise mechanisms underlying the initiation and

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

open access: yesThe Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Articular cartilage and changes in Arthritis: Collagen of articular cartilage

open access: yes, 2002
The extracellular framework and two-thirds of the dry mass of adult articular cartilage are polymeric collagen. Type II collagen is the principal molecular component in mammals, but collagens III, VI, IX, X, XI, XII and XIV all contribute to the mature matrix.

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

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.

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

open access: yesThe Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

In Vivo 3‐Dimensional Glenohumeral Joint Geometry Based Upon Magnetic Resonance Imaging and Computed Tomography Analysis Shows Deeper, Thicker, and Taller Glenoid Labrum Morphology at 12 O’Clock Position in Healthy Young Adults

open access: yesArthroscopy, EarlyView.
Purpose To investigate location‐ and sex‐specific glenoid labrum morphology of healthy young adults in vivo, and the labrum's effects on depth and radius of curvature (ROC) of the glenohumeral joint. Methods Healthy young adults with no history of shoulder surgery, injury, or instability underwent computed tomography and magnetic resonance imaging ...
