Giraffa camelopardalis: limb bone histology through ontogeny
Although there are many studies on mammalian bone histology, there are only a few that have examined the bone histology of artiodactyls, or focused specifically on osteohistological changes during ontogeny. The current study investigates the microanatomy and histology of giraffe limb bones through …

A comparative microscopic study of human and non-human long bone histology.
… of forensic cases. Identification of bone can be difficult, especially in fragmented remains. It has been reported that 25 to 30% of medicolegal cases, which involved nonhuman skeletal remains have been mistaken for human. In such cases, histomorphometric method was used to identify …

Exploring Microstructural Signatures of Physiological Stress through Cross-Sectional Geometry and Cortical Bone Histology
… assessments of stress and health in cortical bone may allow for similar approaches at less severe presentations (i.e., prior to macroscopic lesion formation). However, the specific mechanisms of microstructural responses to physiological stress are unclear. This dissertation explores the …

Insights into the palaeobiology of sauropodomorph dinosaurs through an analysis of their bone histology
… providing key insight into their evolution. Osteohistology studies are well recognised as providing much biological information about the growth dynamics of extinct animals, and several studies have focused on either basal Sauropodomorpha or derived Sauropoda. This research assesses the …

The palaeobiology of the non-mammalian cynodonts deduced from bone microstructure and stable isotopes
… basal to more derived forms was examined using bone cross-sectional geometry and histology, as well as isotope analyses. The bone histology of multiple postcrania revealed distinct variations in growth pattern between the genera studied. The bone histology of the basal Procynosuchus indicates …

Automated human age at death estimation system from long bones histology
Human age estimation at death from bone histology is a frequent and important requirement in forensic anthropology. Usually human age at death is estimated manually from bone histology or morphology. Manual methods of age estimation from bone histology involve three main phases that includes, …

The Multituberculates as Living Animals: New Insights into the Ecomorphology, Behavior, and Life History of One of the Most Successful Mammalian Lineages
… morphology, sedimentology, taphonomy, and bone histology to shed further light on the ecomorphology, behavior, and life history of multituberculates. In particular, this dissertation focuses on the fossil record of the multituberculate subgroup Cimolodonta from the Late Cretaceous through …

The use of histological examination methods to distinguish between the burnt remains of human and non-human bones
Distinguishing between burnt human and non-human bone fragments using macroscopic methods has proved challenging and it was seen in the literature review that the previous research did not all come to the same conclusions. The aim of the research was to determine if, using histological methods, it …

Morphometric study of long bones histology
… of qualitative and quantitative analysis of long bone histology has demonstrated its usefulness in forensic human identification, including age-at-death estimation, human and non-human determination and sex determination. The establishment of an individual biological profile from the measurement …

An Exploration of Histological Variation in the Human Rib: Applications for Age Estimation Methods in Applied Anthropology
… intended for publication in forensic and bone biology journals that address issues related to histological age-at-death estimation of the human rib. The overarching sample for the dissertation consists of N=246 individuals from three North American locations ranging in age from 16-102 …

The use of histological methods to distinguish between burned remains of human and non-human bone
… analysis it is necessary to identify if bone tissue is animal or human in nature. This process is complicated when bone is highly fragmented or burned. Previous research has established the ability to differentiate human from non-human bone histologically, however, further research is …

Functional anatomy, osteogenesis and bone microstructure of the appendicular system of African mole-rats (Rodentia: Ctenohystrica: Bathyergidae)
… anatomy, morphological diversity and postnatal bone morphogenesis of the appendicular system of these subterranean mammals. African mole-rats are small mammals highly adapted to the hypogeous niche that feed on underground roots and tubers. They forage, mate, breed and to some extent even …

Preclinical Evaluation of 3D Printed Biomaterials for Repairing Critical-Size Bone Defects
… of patients each year suffer from non-healing bone defects secondary to trauma, cancer, osteomyelitis, or congenital anomalies. The standard of care for managing these cases necessitates bone reconstruction surgery. Although using autologous bone (autograft) or banked cadaveric bone (allograft) …

A New Quantitative Method for the Taxonomic Identification of Tetrapods

Analyse des Effekts von β-Ecdyson auf die histologische Struktur der proximalen Tibia von gonadektomierten Sprague-Dawley-Ratten
Die Substanz β-Ecdyson stellt einen Hauptvertreter pflanzlicher und tierischer Ecdysteroide dar. Unter anderem durch seine langjährige Verwendung in der traditionellen chinesischen Medizin, werden ihm eine Vielzahl unterschiedlicher Wirkungen bei vergleichsweise geringer Toxizität zugeschrieben. …
