Understanding the spacing of placodes in the eye: A comparative study across age and species

The Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

The Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Cardiac morphological and morphometric analysis of Ardea alba

The Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Sheep Horn Development Revealed by Multi‐Tissue and Cross‐Species Transcriptomic Analysis

Animal Research and One Health, EarlyView.
Multi‐tissue and cross‐species transcriptomics with allele‐specific expression show sheep horns are a composite organ integrating epidermal and osteogenic programs. Conserved horn gene modules and cis‐regulatory variation fine‐tune expression networks underlying horn development and size (small scurs vs. large spiral horns).

Ixekizumab With Tirzepatide Achieved Greater Disease Control Than Ixekizumab Alone in Adults With Psoriatic Arthritis and Overweight or Obesity: Results From a Randomized Clinical Trial

Arthritis &Rheumatology, EarlyView.
Objective Overweight or obesity is prevalent in 72% to 82% of individuals with psoriatic arthritis (PsA). We assessed the efficacy and safety of ixekizumab (IXE) concomitantly administered with tirzepatide (TZP) compared with IXE alone in adult participants with active PsA and overweight with at least one weight‐related comorbidity or obesity.

Arthroscopic Anterior and Posterior Glenohumeral Capsular Augmentation With Gracilis Allograft

Arthroscopy Techniques, EarlyView.
Abstract Multidirectional instability in patients with connective tissue disorders such as Ehlers‐Danlos syndrome (EDS) is difficult to treat due to poor tissue quality and frequent failure of standard repairs. We describe an arthroscopic technique using gracilis tendon allografts to perform an anterior and posterior capsular augmentation in the ...

Single‐Stage Repair of Complex Anterolateral Radial and Posterior Root Tears of the Lateral Meniscus, With a Concomitant Multiligament Knee Reconstruction of the Anterior Cruciate Ligament, Medial Collateral Ligament, Posterior Oblique Ligament, and Anterolateral Ligament in a Young Athlete

Arthroscopy Techniques, EarlyView.
Abstract Early meniscal repair and anatomic reconstruction in a multiligament knee injury optimizes outcomes and restores tibiofemoral mechanics. This technique describes a lateral meniscus posterior root and radial tear repair, with concomitant medial ramp repair, performed during single‐stage reconstruction of the anterior cruciate ligament ...

Combined Arthroscopic Acetabular Labral Reconstruction With Dermal Allograft Hip Capsular Reconstruction

Arthroscopy Techniques, EarlyView.
Abstract Hip instability after arthroscopy is a rare but challenging complication which can result from iatrogenic capsular deficiency and labral insufficiency. When accompanied by acetabular undercoverage, this combination compromises both the static and dynamic stabilizers of the hip joint, predisposing patients to pain, dysfunction, and progressive ...
