Regional and Seasonal Effects on Long Bone Fracture Characteristics
… skeletal trauma to determine the timing of bone fractures. Differentiating between perimortem trauma and postmortem damage is especially complicated due to the variable timing of bone degradation and subsequent changes in fracture morphology. Different investigations into the timing at which …

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 …

Understanding the mechanism of injury associated with long bone fractures through dynamic bending impact
… that all butterfly fractures are produced due to bone failing in tension. Furthermore, it requires the presence of a detached piece in order to be applicable, which is also the case for other proposed methods. The current study explores the biomechanics involved in the production of butterfly …

A comprehensive analysis of long bone curvature in Neanderthals and modern humans using 3D morphometrics
… landmark and semi- landmark analysis to quantify bone curvature (femur, ulna, radius) in Neanderthals, Upper Palaeolithic and recent modern humans, 2) compare adult bone curvature between these populations, and 3) test hypotheses on the effects of climate, body size, and activity patterns on …

Multi-scale characterization of swine femoral cortical bone and long bone defect repair by regeneration
… of structure and mechanical properties of bone as a function of age and regeneration of bone in long bone critical sized defects. In the first part of this study, a multi-scale experimental work was carried out to characterize cortical bone as a heterogeneous material with hierarchical …

Characterization of the early stages of long bone regeneration in fractures and critical size defects in Xenopus Laevis
… irradiation can cause critical sized defects in long bones. Regeneration capabilities of most mammals in their long bones are robust in small defects such as fractures but diminish in large defects due to lack of proper cellular cues. A small animal in vivo model has been developed to study the …

Investigation of the Body Segment Inertial Properties and Long Bone Geometries of a Mid-Sized Male Finite Element Model
Simulations of complex blunt trauma events have become possible due to advances in computational human body modeling via finite element analysis.[3-8] These models have the potential to elucidate previously unknown injury mechanisms and can inform regulatory agencies directed at public health and …

Childhood Growth In An Oneota Community: Examining Long Bone Growth Differences In The The Juveniles At Norris Farms 36
… injuries at the Norris farms 36 cemetery, along with biological markers for poor health, such as cribra orbitalia and porotic hyperostosis. They suggested that the threat of violence may have forced the Oneonta at Morton village to limit subsistence activities to circumscribed areas close to …

Bone Mineral Density In Hiv: A Comparison Of Hiv Positive Versus Negative Patient With Lower Limb Long Bone Fractures
… a global health issue causing a deterioration in bone microarchitecture, compromising bone strength. In South Africa (SA), the prevalence of osteoporosis is a growing concern for both HIV-positive and HIVnegative individuals. The aim of this study was to assess the impact of HIV infection on bone …

Tissue-specific behavioural signatures in cortical and trabecular bone. Variations in long bone structure in medieval Britain, and the differential effects of age.
… structural properties of cortical and trabecular bone in the limbs are compared in three groups from a medieval British population. Since both tissues have been shown to adapt to mechanical loading, anthropologists have interpreted the morphology of either cortical or trabecular bone as a record …

Comparison of the long bone microstructure of two southern African marine birds, the Cape gannet (Morus capensis) and the African penguin (Spheniscus demersus) with respect to their aquatic adaptations
… using only its forelimbs. In this study, the long bones of ten penguins and nine gannets were compared in terms of microanatomy and histology with respect to ontogenetic stage (hatchlings, juveniles and adults) and locomotion. Micronatomical and histological findings of the fore-limbs and hind …

Explorations into Appendicular Ontogeny using a Cross-Sectional, Contemporary U.S. Sample
… anthropology. Alternatively, the same source of longitudinal data has been repeatedly used, which does not reflect the variability of growth and development (i.e., ontogeny) or the United States (U.S.) population. Small and/or homogenous samples have often resulted in limited or inappropriate …

Osteoimmunological Characterization of Borrelia burgdorferi-Induced Bone Loss: From Phenotype to Molecular Mechanisms
… and disseminates to various tissues, including bone. B. burgdorferi induces trabecular long bone loss in murine models, but its phenotype and molecular mechanisms remain unknown. Furthermore, it is not known if B. burgdorferi induces loss of alveolar bone (supporting teeth). We first conducted …

Sexual Dimorphism and Socioeconomic Status: Comparison between Migrant and Non-migrant Populations
… relies on male susceptibility to impairment in long bone length during episodes of stress, while females are buffered from the same conditions due to reproductive demands (Charisi et al. 2011; Frayer and Wolpoff 1985; Gray and Wolfe 1980; Greulich 1951; Rickland and Tobias 1986; Stini 1969; …

AN ASSESSMENT OF SUBADULT SKELETAL GROWTH AND DEVELOPMENT BASED ON A MICHIGAN MEDICAL EXAMINER SAMPLE

Pleistocene Peccaries from Guy Wilson Cave, Sullivan County, Tennessee.
… nasutus</em> from other Pleistocene-aged sites. Long-bone NISP and age profiles show a predominance of <em>Platygonus</em> adults. Tayassuidae upper canines, likely <em>Platygonus</em>, suggest sexual dimorphism. Long bones were analyzed for carnivore damage and utilization revealing light …
