Diaphyseal remodelling is a pathological process of the proximal phalanges, metatarsals and metacarpals in all established types of clinical leprosy. It is suggested that the changes are the result of sympathetic neuropathy and alteration of peripheral vascular bed dynamics selectively stimulating extracortical osteoclastic and endosteal osteoblastic activity. There is an overall loss of diaphyseal cortical diameter, either in concentric or knife-edge pattern. There is extracortical absorption of bone and coincident endosteal bone deposition. Ultimately, there is diaphyseal pathological fracture, and subsequent resorption of the distal and proximal remnants due to combined continued diaphyseal remodelling and achroosteolysis.  相似文献

The rhinomaxillary syndrome consists of a group of maxillary bone changes, which may be present in part or in total, in lepromatous and near-lepromatous leprosy. The changes are a composite mixture of erosive, absorptive and proliferative bone reactions. The anatomical zones involved are the alveolar process of the maxilla, the anterior nasal spine, the palatine process of the maxilla, intranasal osseous structures, and the margins of the nasal aperture.  相似文献

The third intercondylar tubercle of Parsons (TITP) is a bony protuberance which is sometimes present on the tibial plateau. It corresponds to the insertion of the anterior fibres of the anterior cruciate ligament (ACL). Reasons why TITP is present in some knees and not others are at present unclear. TITP is studied in knee joints from 68 adult individuals from a medieval cemetery. Associations are investigated with age, sex, knee osteoarthritis, clinical and subclinical DISH, and skeletal signs of trauma, with the aim of evaluating existing ideas on the causation of TITP. Only trauma showed an association with the presence of TITP. The results offer support for the aetiology of trauma to the ACL in the formation of TITP.

The object of this communication is to draw attention to the appearance of this fossil talus Stw 363, which carries a densely adherent fragment on its posterosuperior aspect. We have endeavoured to verify that this bony fragment could be the posterior half of the fractured calcaneus resulting from a fall on to the animal's left foot. Furthermore, it is suggested that this animal survived long enough for this fracture to unite by bone to the posterior aspect of the talus in this grossly displaced and unreduced deformity.  相似文献

We present real‐time observations of polycrystal growth experiments in transmitted light in an accurately controlled flow system with the analogue material alum [KAl(SO4)2·12H2O]. The aim of the experiments is to obtain a better insight into the evolution of vein microstructures. A first series of experiments shows the evolution of a polycrystal at supersaturations between 0.095 and 0.263. The average growth rate of the crystals is influenced by growth competition and the depletion of the solute along fracture length. Growth competition is controlled by crystallographic orientation, crystal size and crystal location. In addition, the growth rate of an individual crystal facet also shows variations depending on the facet index, facet size and flow velocity. These variations can influence the morphology of the grain boundaries and the microstructures. The aim of the second series of experiments is to investigate the growth evolution of rough/dissolved facets in detail. The growth distance required for the development of facets is around 15 μm. In all the experiments, we observe that the measured growth rates have a much larger range than predicted by alum single‐crystal growth kinetics. This is due to the combined effect of the facet index and the crystal size. Furthermore, at high supersaturations, the facet growth rate measurements do not fit the same growth rate equation as for the experiments at lower supersaturations (<0.176). This can be explained by a change in the growth mechanism at high supersaturations with more influence of volume diffusion, relative to advection of the bulk solution on the growth rate. This effect can also cause a more homogeneous sealing pattern over fracture length. At high supersaturations, the larger crystals in these experiments incorporate regularly spaced fluid inclusion bands and we propose that these can be used as an indicator for high palaeo‐supersaturation. The final microstructures of the experiments show no asymmetry with respect to the flow direction.  相似文献

Bioarchaeologists have conducted numerous studies on human skeletal remains using metacarpal cortical bone radiogrammetry. This method allows cortical thickness of the second metacarpal to be quantified. As a sensitive index of bone health metacarpal cortical thickness is evaluated in the context of functional adaptations, growth, ageing and bone loss in osteoporosis, as well as used as a reliable indicator of fracture risk. The focus of this study is an examination of the widely used calculation that expresses second metacarpal cortical bone values, followed by an examination of age and sex-related patterns of cortical bone loss and skeletal fragility fracture in a Neolithic archaeological skeletal sample from Çatalhöyük, Turkey. Using metacarpal radiogrammetry, 49 adult metacarpals (f = 27 m = 22) were examined. Data were collected for size variables, length (L) and total bone width (TW) as well as quantity variables, medullary width (MW) and cortical thickness (CT). These parameters were then used to calculate the widely used cortical index (CI) and two new indices expressing medullary width and cortical bone thickness in relation to length (medullary width index, MWI and cortical thickness index, CTI). The ratios were then used to explore age- and sex-related cortical bone loss and fragility fracture patterns amongst the inhabitants of Çatalhöyük. Çatalhöyük males and females demonstrate an inverse relationship where CTI decreases as age and MWI increase. Analyses indicate statistically significant age-related change in MWI amongst the oldest females. Despite age-related loss of bone, no typical fragility fractures are observed. We discuss the role of ageing and lifestyle factors at Çatalhöyük that may have been beneficial to skeletal health and a reduction in the risk of fragility fracture.  相似文献

Electron spin resonance and infrared spectroscopic techniques have been used to examine the thermal and environmental deterioration of ivory from Nimrud, Iraq. It has been possible to ascertain the extent of ancient pyrolysis of the ivory with the former technique, and infrared spectroscopy has allowed an insight into the deterioration of the protein matrix of the ivory both in relation to, and independent from, thermal breakdown. Comparative spectroscopic studies of both ancient and modern ivory are also reported. The structural information obtained is discussed in the light of previously reported studies based upon chemical analyses.  相似文献

Traditional interpretations of how the Inka empire developed emphasize the disjunctive transformation of a village-level society through the agency of a single charismatic ruler. New evidence from the Inka heartland indicates that it was in fact the formation of a centralized state in the Cusco Valley of highland Peru that enabled the rapid campaigns of Inka territorial expansion during the 15th and 16th centuries. By using archaeological data and ethnohistoric documents to develop independent lines of evidence, it is possible to describe Inka state formation processes anthropologically. Settlement and excavation data from the Vilcanota Valley provide several indicators of the development of a centralized Inka state during the Killke Period (c. A.D. 1000–1400), while multiple accounts of the Inka past describe the transformation of Inka society over a period of several generations leading up to the first campaigns of imperial conquest. Both lines of evidence are consistent with the kinds of changes described for other known cases of state formation. The formation of the Inka state and its expansion in the Cusco region created conditions in which the agency of Inka rulers could direct the expansion of a mighty empire in only a few generations of conquest.  相似文献

The chemical compositions and microstructures of some 35 faience objects from Egypt spanning the period from the Middle Kingdom through to the 22nd dynasty are determined using analytical scanning electron microscopy. Replicate faience beads glazed in the laboratory using the efflorescence and cementation methods are similarly investigated. In efflorescence glazing, there appears to be preferential efflorescence of soda over potash, and in cementation glazing, preferential take up of potash over soda into the glaze. These data are then used to try to infer the raw materials and methods of glazing employed in the production of the ancient faience. The glaze/glass phases present in the faience differ significantly in composition from that of New Kingdom glass. This could be due either to the use of different plant ashes or to changes in the composition of the plant ashes during the production of faience and/or glass. Although it is only rarely possible to determine with certainty whether ancient faience was glazed by efflorescence, cementation or application, the observed microstructures provide an indication of the approach adopted to achieve desired performance characteristics such as strength.  相似文献

大革命失败后中国革命向何处去的问题,引出了长达10年的中国社会性质、社会史问题的大论战。论战中陶希圣写下了大量的著作,其深度是当时绝大多数人不能比的,提出的看法直到今天仍能给人以启示。20世纪80年代以来,大陆学术界对本次社会史论战开展评论,不少人从陶希圣反对共产党的政治主张出发,认为他的社会史观点经常改变,所论也不符合中国历史的实际。我们认为这种评价政治倾向重于学术研究,又缺少对于陶氏社会史研究的具体分析,其做法是有违实事求是地看待历史问题的马克思主义史学观点的。  相似文献

The occurrence of imported Mycenaean pottery in the Late Bronze Age southern Levant is one of the most conspicuous aspects of Eastern Mediterranean trade connections during this period. A group of 183 Mycenaean pottery vessels from 14 sites in northern Israel, from both coastal and inland settlement contexts were analyzed by Neutron Activation Analysis. The results indicate that the vast majority of these vessels have a similar profile and can be provenanced to the north-eastern Peloponnese or more specifically, to the Mycenae/Berbati workshop in the Argolid. Possible interpretations of these results are presented and discussed against the historical and cultural background of the Late Bronze Age Eastern Mediterranean.  相似文献

The organization of Classic Maya society emerged from diverse and overlapping social interactions which shaped a dynamic political landscape. Vying for power, elites legitimized their status by claiming ancestry from various supernaturals and engaged in conspicuous displays of competition, warfare, and ritual practice which were often recorded on stone monuments. By examining the inscribed relationships between Maya centers, we chart organizational changes in sociopolitical networks throughout the Classic period. Methods derived from social network analysis are used to examine temporal changes in the distribution and centralization of political power through different network interactions. We examine the intersection of antagonistic, diplomatic, subordinate, and kinship relationships and discuss how these overlapping networks contributed to dynamic changes in the Classic period. This case study demonstrates how current network analysis techniques can contribute to archaeological studies of the scalar dynamics and organizational changes of past social and political systems.  相似文献
