Development of a deep learning method for phase retrieval image enhancement in phase contrast microcomputed tomography

Journal of Microscopy, EarlyView.
Abstract Propagation‐based imaging (one method of X‐ray phase contrast imaging) with microcomputed tomography (PBI‐µCT) offers the potential to visualise low‐density materials, such as soft tissues and hydrogel constructs, which are difficult to be identified by conventional absorption‐based contrast µCT.

Bipedalism or bipedalisms: The os coxae of StW 573

Journal of Anatomy, EarlyView.
There has been a long debate about the possibility of multiple contemporaneous species of Australopithecus in both eastern and southern Africa, potentially exhibiting different forms of bipedal locomotion. Here, we describe the previously unreported morphology of the os coxae in the 3.67 Ma Australopithecus prometheus StW 573 from Sterkfontein Member 2

The osteohistology of Orthosuchus stormbergi using synchrotron radiation microcomputed tomography

Journal of Anatomy, EarlyView.
The osteohistology of Orthosuchus stormbergi is described for the first time. The primary bone tissue was lamellar bone. It had relatively thick bone walls, possibly indicating an aquatic lifestyle. Orthosuchus was a small bodied adult reaching a maximum body mass of about 1.2 kg.

Epidermal scale growth, allometry and function in non‐avian dinosaurs and extant reptiles

Journal of Anatomy, EarlyView.
Scale shapes in non‐avian dinosaurs and extant reptiles are mostly retained through growth. However, positive scale allometry and proportional differences in scale breadth are also detected, which are likely associated with changing body proportions. Based on their generally conserved morphology and impracticality for visual display, the enlarged size ...

Computed microtomographic imaging of revascularization during healing of Achilles tendon injury

Journal of Anatomy, EarlyView.
This study explores the role of vascularization in tendon healing by comparing physiological and pathological angiogenesis. Using micro‐CT imaging, we identified distinct changes in vascular organization following injury, highlighting the dynamic interplay between angiogenesis and tendon pathology.

Osteohistological analysis of metatarsals reveals new information on pathology and life history of troodontids from the Campanian Dinosaur Park Formation, Alberta, Canada

Journal of Anatomy, EarlyView.
A histological survey of troodontid metatarsals from the Dinosaur Park Formation (DPF) was conducted, revealing correlates for stresses in the troodontid arctometatarsus and providing the first histological assessment of pathologies for this taxon.

Osteohistology of the Maastrichtian, small‐bodied elasmosaurid Kawanectes lafquenianum (Sauropterygia; Plesiosauria)

Journal of Anatomy, EarlyView.
The present contribution brings new osteohistological information on the postcranial bones of Kawanectes lafquenianum and shed some light on Plesiosauria microanatomy and microstructure. The bone architecture shows variability between forelimbs and hindlimbs.

The locomotor ecology of wild western lowland gorillas: How does the largest ape exploit complex arboreal environments?

Journal of Anatomy, EarlyView.
When travelling and feeding in the canopy, the western lowland gorillas engaged in bipedal locomotion likely as a strategy to mitigate the risk of falling at the cost of increased energy expenditure. Abstract Western lowland gorillas are the largest and most sexually dimorphic ape that habitually exploits arboreal environments.
