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

open access: yesThe 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 ...

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

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 ...

The effect of laying hen strain on perching biomechanics and keel deviations

open access: yesJournal of Applied Poultry Research
SUMMARY: Keel bone damage (KBD), including deviations and fractures, is a welfare concern in laying hens leading to pain and decreased egg production. Shifting towards alternative housing systems has highlighted a need to evaluate how laying hen strain ...

A comprehensive embryonic staging series of the turtle Trachemys scripta

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

The role of Rho GTPases in facial morphogenesis

open access: yesDevelopmental Dynamics, EarlyView.
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion. Fnm, frontonasal mass; lnp, lateral nasal process; mnp, medial nasal process; mxp, maxillary process; np, nasal

Addressing Heterogeneity in Binge Eating Disorder: A Cluster Analysis Approach Based on Age of Onset, Clinical and Psychopathological Features

open access: yesEuropean Eating Disorders Review, EarlyView.
ABSTRACT Objective This study investigates clinical heterogeneity in patients with binge eating disorder (BED) and its association with treatment outcomes. Methods A two‐step cluster analysis was conducted on a clinical sample of 196 BED patients, using an agglomerative hierarchical procedure based on both categorical and quantitative measures ...

Reduced Dietary Protein Induces Changes in the Dental Proteome

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Low dietary protein (10%) from normal (20%) does change protein expression in tooth proteome and alter developmental pathways. Among the significant protein expressions changes are actin‐based myosins, tooth, and bone development proteins. Perplexingly tooth size is not altered, suggesting more nuanced phenotypic response to low dietary protein in ...

Effect of Environmental Enrichment Within Cages on Production and Welfare in Laying Hens [PDF]

open access: yesBrazilian Journal of Poultry Science
This study aims to compare the effects of conventional cage systems (CC) and environmentally enriched cage systems (EEC) (which include nest boxes, perches, and pecking stones) on the productivity and welfare of laying hens, also considering the ...

The Importance of Modeling Press‐Fit to Accurately Evaluate Interfacial Micromotion as an Indicator of Primary Stability in Uncemented Arthroplasty

open access: yesJournal of Orthopaedic Research, EarlyView.
ABSTRACT Arthroplasty is most often performed to alleviate pain and restore function in patients with end‐stage degenerative joint disease. Uncemented implant fixation is increasingly used in total knee and total ankle arthroplasty. Implantation using interference press‐fit is a manufacturer‐recommended guideline for achieving stable primary fixation ...
