Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

The relationship between form and function of the carnivore mandible

open access: yesThe Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Effects of intermittent exposure to hypobaria and cold on the microarchitecture and morphofunctional profile of rat gastrocnemius muscle

open access: yesThe Anatomical Record, EarlyView.
Abstract Intermittent hypobaric hypoxia (IHH) enhances oxygen transport, muscle metabolism, and cardiovascular health; however, the combined effects of hypobaria and cold are less well understood. Exposure to these stressful environmental factors, even intermittently, can affect skeletal muscle due to its plasticity, thereby altering its metabolic and ...

Morphometric analysis of postnatal lung development in the gray short‐tailed opossum (Monodelphis domestica): An ultrastructural study

open access: yesThe Anatomical Record, EarlyView.
Abstract An ultrastructural morphometric analysis of the postnatal development of the lung in the gray short‐tailed opossum (Monodelphis domestica) has been conducted to evaluate the morphofunctional status of this poorly developed marsupial lung immediately following parturition.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Comprehensive Characterization of Acer truncatum Leaf Extract: Identification of Systemic Metabolites and Effects on Performance, Antioxidant Status, and Intestinal Microbiota in Laying Hens

open access: yesAnimal Research and One Health, EarlyView.
Dietary A. truncatum leaf extract is absorbed and improves laying performance in aged hens by enhancing systemic antioxidant capacity and modulating the gut microbiota. ABSTRACT The demand for natural feed additives is considerably increasing in the antibiotic‐free feed era.

The hare and the tortoise: Open access publications' immediate impact and lasting advantage

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract Open Access has changed how research is published and discovered. Studies generally report that OA articles are cited and mentioned more often than non‐OA, describing an open access advantage (OAA). The mechanisms causing the OAA are under‐investigated: this research analyzes citation and altmetrics post‐publication, reporting on the ...

Mapping opioid exposure through prescription data and postmortem analysis of opioid drugs in multiple tissues

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Background and Purpose Although opioids are central to end of life (EoL) care, tissue‐level opioid exposure remains poorly understood. The objective of this study was to characterize the relationship between prescription‐derived morphine equivalent daily dose (MEDD) and measured morphine concentrations across multiple organs.

A phase 1 evaluation of inhaled oxytocin: Physiologically‐based pharmacokinetic model informed dosing of a novel heat‐stable oxytocin delivery system

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim To develop and validate a physiologically‐based pharmacokinetic (PBPK) model enabling inhaled oxytocin dose selection for clinical evaluation. Subsequently, to conduct a phase 1 study investigating the pharmacokinetics and safety of selected doses of an optimized inhaled oxytocin product in healthy, non‐pregnant female participants.
