Clade‐wide morphological and functional variation of the sauropsid columella

open access: yesThe 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.

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

open access: yesThe Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

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.

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis

open access: yesThe Anatomical Record, EarlyView.
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

open access: yesThe Anatomical Record, EarlyView.
Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...

Mapping the distribution of Meissner corpuscles throughout the human hand: Sex‐ and age‐dependent variations

open access: yesThe Anatomical Record, EarlyView.
Abstract Meissner corpuscles are rapidly adapting mechanoreceptors involved in tactile discrimination in human glabrous hand skin. Detailed information on their regional distribution and variation across age, sex, and hand side remains limited. This study mapped Meissner corpuscles in 17 phalangeal and palmar regions from 46 individuals (27 male and 19

Emotion Regulation Difficulties in Autism‐PTSD Co‐Occurrence

open access: yesAutism Research, EarlyView.
ABSTRACT Autistic individuals face an increased risk of experiencing traumatic events and of being significantly affected by them, whether these events are life‐threatening or social in nature. Emotion regulation (ER) difficulties are central to both conditions, yet their role in this neuropsychiatric co‐occurrence remains under‐researched.

Systematic review of clinical trials and cohort studies evaluating HIV post‐exposure prophylaxis (PEP) regimens to inform updated Canadian guidelines

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Background We conducted a systematic review of clinical trials and cohort studies on HIV post‐exposure prophylaxis (PEP) regimens to inform updated 2025 Canadian guidelines. Methods We searched Medline and Embase (July 2017–June 2024) for studies reporting on: HIV acquisition, PEP completion, adverse events (AEs) leading to discontinuation and/

Socioeconomic status, parenting factors and academic achievement among Chinese adolescents aged 12–13: How do they relate?

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Extensive research has shown that students from higher socioeconomic status (SES) backgrounds generally outperform their lower SES peers. Nevertheless, some low SES students succeed, albeit it ‘against the odds.’ Coleman's (1988) theory of social capital in the family suggests that financial capital, human capital and social capital all affect

Fibroproliferative Remodeling of Immune‐Vascular Co‐Culture Spheroid Models in Response to Atherogenic Stimulation

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Cell‐based models are highly valuable platforms for preclinical studies of atherosclerosis, offering controllable environments to investigate disease mechanisms. Three‐dimensional (3D) spheroids, a class of cell‐based models, enable the study of atherosclerotic disease phenomena under physiologically relevant yet controlled conditions. In this
