Subchondral bone histology and grading in osteoarthritis. [PDF]

open access: yesPLoS ONE, 2017
OBJECTIVE:Osteoarthritis (OA) has often regarded as a disease of articular cartilage only. New evidence has shifted the paradigm towards a system biology approach, where also the surrounding tissue, especially bone is studied more vigorously.

Long bone histology and growth patterns in ankylosaurs: implications for life history and evolution.

open access: yesPLoS ONE, 2013
The ankylosaurs are one of the major dinosaur groups and are characterized by unique body armor. Previous studies on other dinosaur taxa have revealed growth patterns, life history and evolutionary mechanisms based on their long bone histology.

Limb bone histology records birth in mammals. [PDF]

open access: yesPLoS ONE, 2018
The annual cyclicality of cortical bone growth marks (BGMs) allows reconstruction of some important life history traits, such as longevity, growth rate or age at maturity.

Histovariability and Palaeobiological Implications of the Bone Histology of the Dromornithid, Genyornis newtoni

open access: yesDiversity, 2021
The bone microstructure of extinct animals provides a host of information about their biology. Although the giant flightless dromornithid, Genyornis newtoni, is reasonably well known from the Pleistocene of Australia (until its extinction about 50–40 Ka),

Bone histology of eosauropterygian diapsid Proneusticosaurus silesiacus from the Middle Triassic of Poland reveals new insights into taxonomic affinities [PDF]

open access: yesActa Palaeontologica Polonica, 2021
The status of Proneusticosaurus silesiacus from the Lower Muschelkalk (lower Anisian) of Poland is controversially discussed. Its femur was histologically sampled to learn more about its taxonomic affinities and life style.

Shell and long-bone histology, skeletochronology, and lifestyle of Araripemys barretoi (Testudines: Pleurodira), a side-necked turtle of the Lower Cretaceous from Brazil

open access: yesAnais da Academia Brasileira de Ciências, 2021
In this study we provide a comprehensive investigation of the microanatomical and microstructural aspects of the carapace and limb bones of the Early Cretaceous side-necked turtle, Araripemys barretoi, from the Araripe Basin, Brazil.

Osteonal Microcracking Pattern: A Potential Vitality Marker in Human Bone Trauma

open access: yesBiology, 2023
In forensic anthropology, the differential diagnosis between peri- and postmortem bone fractures is mainly based on macroscopic criteria. In contrast, studies focusing on bone histology are very scarce. In a recent publication, we showed that (perimortem)

The Effects of Experimental Whole-Body Burning on Histological Age-at-Death Estimation from Human Cortical Bone and Dental Cementum

open access: yesBiology, 2022
Whole-body donations (n = 6) were placed in various experimental fire-death scenarios to understand the histological effects of thermal alteration on bones and teeth. Midshaft samples of the femur, 6th rib, and metatarsal were removed from each donor pre-

Variation and process of life history evolution in insular dwarfism as revealed by a natural experiment

open access: yesFrontiers in Earth Science, 2023
Islands are a classic focus for evolutionary studies. One topic of great interest has been the evolution of “dwarfs,” significantly smaller island mammals relative to their continental counterparts.
