The sequence of appearance of the 17 different skull bones in the oriental fire-bellied toad, Bombina orientalis, is described. Data are based primarily on samples of ten or 11 laboratory-reared specimens of each of 11 Gosner developmental stages (36-46) representing middle through late metamorphosis. Ossification commences as early as stage 37 (hind limb with all five toes distinct), but the f...

McCune Albright syndrome (MCA) is a rare complication of genetic origin. The authors present a case study of a patient with MCA diagnosed with multifocal fibrous dysplasia in his limb and craniofacial bones. The symptoms of the disease in the patient's facial and oral tissue and the treatment administered have been described.

During the archaeological excavation of a multicultural settlement at the Nitra-Chrenova site (southwestern Slovakia) an assemblage of animal bone remains was revealed. In one of the settlement features dated to the Roman period a complete horse skeleton was discovered. An investigation was carried out in the hind limb of the horse’s skeleton involving macroscopic and radiographic analysis. Exo...

Since fi rst discovered in the early 19th century, the ossuaries from Bushehr, Persian Gulf, have attracted attention as possible archaeological evidence for ancient Zoroastrian burial practice. Th is practice involved exposing cadavers to birds before the surviving remains were gathered for deposition in an ossuary. In this paper, the human remains recovered from two ossuaries at Bushehr are d...

One of the main events in the history of our species has been our expansion out of Africa. A clear signature of this expansion has been found on global patterns of neutral genetic variation, whereby a serial founder effect accompanied the colonization of new regions, in turn creating a wilhin-pupulation decrease in neutral genetic diversity with increasing distance from Africa. This same distin...

Introduction. Skills training using artificial bones became more critical in response to the Orthopedic surgical restriction caused by COVID-19 pandemic. To cut expenses of buying commercial bones, Ilizarov Limb Reconstruction Service has decided fabricate its for skills training. Objective. determine if resin-coated polyurethane (PU) rigid foam is a suitable, low-cost alternative bone. Metho...

Most studies examining changes in mechanical performance in animals across size have typically focused on inter-specific comparisons across large size ranges. Scale effects, however, can also have important consequences in vertebrates as they increase in size and mass during ontogeny. The goal of this study was to examine how growth and development in the emu (Dromaius novaehollandiae) hindlimb...

An estimated 1,170 white (Ceratotherium simum), black (Diceros bicornis), greater one-horned (Rhinoceros unicornis), and Sumatran (Dicerorhinus sumatrensis) rhinoceroses are kept in captivity worldwide, where they are a popular public attraction and serve important roles in education and conservation. Rhinoceroses in captivity are reportedly affected by a variety of foot conditions, including a...

In this article, we are interested in the modelling of the lower limb anatomical structures such as bones, muscles and tendons. The proposed method starts with an MRI acquisition during which the lower limb of a subject is scanned. 3D models are generated after a manual segmentation of the anatomical structures. However, the surface of the generated models appears not to be smooth. Furthermore,...

Mechanical stimuli are essential for the skeleton, and immobilization produces rapid bone loss in the weight-bearing bones (Peng et al. 1994). It is probable that a reduction of physical activity may also affect the involutional osteopenia seen in elderly people. Immobilization of a limb provides an experimental way to study mechanical influences on bone tissue without interfering with hormonal...
