Protected by the mineral matrix, bone proteins are capable of surviving inhumation periods of several hundreds or thousands of years in soil. While the preservation of the bone matrix protein, collagen I, is the prerequisite for a variety of archaeometric approaches, such as radiocarbon dating and the reconstruction of palaeodiet by stable isotope analysis, little is known about both the rate and state of preservation of non‐collagenous proteins. We succeeded in the isolation, electrophoretic separation (SDS‐PAGE, IEF) and immunological detection (radial immunodiffusion, IEF immunoblotting and ELISA) of plasma proteins preserved in archaeological human bones. However, sample preparation and electrophoretic methods had to be adapted to the specific demands of these aged proteins, since they are not only degraded and fragmented but also cross‐linked to other organic components, either indigenous to the bone or to contaminants from the burial environment. Complex decomposition phenomena are responsible for the altered mode of migration of aged proteins through a gel. After isoelectric focusing, the ancient proteins mainly concentrate below pH 4.45 in the pH‐gradient. Thus, highly negatively charged protein components have a better chance of preservation in bone after death. Isoelectric focusing with subsequent immunoblotting of ancient protein samples revealed protein patterns which showed marked charge‐modifications in comparison with those of modern human plasma proteins due to protein degradation (e.g. α2‐HS‐glycoprotein and α1‐antitrypsin). Nevertheless, in combination with different immunological analyses, previous results concerning the selective enrichment of α2‐HS‐glycoprotein in bone compared with other plasma glycoproteins could be confirmed.

By means of scanning electron microscopy, four out of a series of twelve inhumations from the Hellenistic Period were examined for traces of the decay process. The changes represented the result of erosion and biological decomposition of human bones on a small island in the northern part of the Persian Gulf over a period of ca. 2200 years. Special emphasis was given to bone preservation and blood cell survival, and to bone changes due to physicochemical erosion and fungus, bacterium, insect and plant-root activity. Related soil and climatic conditions were taken into consideration. The observations should be evaluated to understand the unusual state of preservation of the bones and to avoid possible misinterpretation of pseudo-pathological bone changes as ante-mortem pathology.  相似文献

Ancient Chinese dogs excavated at three archaeological sites and stored in the Institute of Vertebrate Paleontology and Paleoanthropology, Academia Sinica, were the object of this study (Xiawanggang site, 5000–6000 years BP; Keshengzhuang site, 3000–4000 years BP; Shangsunjia site, Bronze age). During these periods, there were large morphological variations in Chinese dogs beyond a single dog class, as with Jomon dogs. Dogs with a large ‘stop’ were already present in China but not in Japan. At the Keshengzhuang site, middle to large class dogs were also excavated. At least three types were confirmed within these dogs. In the aged dog in Xiawanggang, antemortem loss of many teeth was observed suggesting active use of the teeth and it is possible that this dog was used for hunting as were the Japanese Jomon dogs. © 1998 John Wiley & Sons, Ltd.  相似文献

Bone collagen is a well-characterized and generally robust protein that plays a key role in both radiometric dating and stable isotopic reconstruction of paleodiet. To be useful for such purposes, however, analyzed collagen must be relatively taphonomically unaltered. To date, little research has been conducted to document the taphonomic fate of bone collagen from archaeological sites in the tropics. In the present work, a large (n = 298) dataset of archaeological bone samples from sites on the island of Puerto Rico is examined by means of radiometric, chemical, and elemental analyses. The ultimate conclusion of this work is that while collagen loss may be accelerated in the tropics versus that seen in samples from higher latitudes, what collagen remains is typically sufficiently well-preserved and taphonomically unaltered as to make radiocarbon dating and/or stable isotopic analysis worthwhile.  相似文献

Syrian archaeological pottery sherds were collected for TL dating from six different archaeological sites named Al-Shermanieh, Tell Serah, Der Al-Hajar (south of Damascus), Tell Al-Shekdakah, Tell Al-Souwirieh (east of Damascus) and Khurbet Al-Kulieh (south west of Damascus). The samples were prepared by fine grain technique and the annual dose for each sample (pottery sherds and soil sample) was measured using an alpha spectrometer system for uranium and thorium contribution as well as with atomic absorption spectrometry for the potassium contents. The mean ages were found to be 5500 ± 150 years, 2950 ± 50 years, 1200 ± 50 years, 1300 ± 150 years, 3300 ± 100 years and 3400 ± 200 years for the examined pottery from the sites Al-Shermanieh, Tell Serah, Der Al-Hajar, Tell Al-Shekdakah, Tell Al-Souwirieh and Khurbet Al-Kulieh, respectively. The results were in good agreement with the ages estimated by archaeologists except for one sample which belongs to Der Al-Hjar site.  相似文献

Using multivariate techniques, several skulls of fossil large canids from sites in Belgium, Ukraine and Russia were examined to look for possible evidence of the presence of Palaeolithic dogs. Reference groups constituted of prehistoric dogs, and recent wolves and dogs. The fossil large canid from Goyet (Belgium), dated at c. 31,700 BP is clearly different from the recent wolves, resembling most closely the prehistoric dogs. Thus it is identified as a Palaeolithic dog, suggesting that dog domestication had already started during the Aurignacian. The Epigravettian Mezin 5490 (Ukraine) and Mezhirich (Ukraine) skulls are also identified as being Palaeolithic dogs. Selected Belgian specimens were analyzed for mtDNA and stable isotopes. All fossil samples yielded unique DNA sequences, indicating that the ancient Belgian large canids carried a substantial amount of genetic diversity. Furthermore, there is little evidence for phylogeographic structure in the Pleistocene large canids, as they do not form a homogenous genetic group. Although considerable variation occurs in the fossil canid isotope signatures between sites, the Belgian fossil large canids preyed in general on horse and large bovids.  相似文献

Abstract

The use of ancient theatres for present-day performances was the subject of a colloquium organized by the Council of Europe in September 1995 which gave rise to the ‘Segesta Declaration’ concerning the protection and proper use of ancient places of performance. These include theatres, amphitheatres, stadia, hippodromes and arenas with origins in the Greek and Roman periods. The following note draws upon a summary of the colloquium, held in Trapani, Segesta and Palermo in Sicily, and reproduces the text of the recommendations of the Segesta Declaration.  相似文献

程毅中 《文献》2004,(2):194-205
中国古代小说的研究,首先离不开文献的整理.因此近百年来的古代小说研究,文献学研究的成果占了很大比重.我在这里根据自己的了解和摸索,试作一些介绍和分析. 一、关于小说的目录 古代小说的概念非常宽泛,历来史志书目所著录小说的范围广狭各不相同.如郑樵所说,小说常与传记、杂家、杂史、故事相混.古人所谓的小说,我们今天很难给它定性.  相似文献

The origin and evolution of the infectious disease tuberculosis (TB) and its pathogens is still not fully understood. An important effort for a better understanding of the underlying mechanisms of TB evolution lies within the investigation of skeletal and mummified material dating back several thousand of years. In this work, molecular data from mummified and skeletal material from different time periods of the Old World are compared, and the current status of ancient mycobacterial DNA analysis in ancient human remains is discussed, with particular reference to the genetic evolution of human TB. The molecular analysis of material from southern Germany (1400–1800 AD), Hungary (600–1700 AD) and Egypt (3500–500 BC) revealed high frequencies of TB in all time periods. In several individuals from ancient Egypt the mycobacterial DNA could be further characterised by spoligotyping. Thereby, evidence for ancestral M. tuberculosis strains was found in the pre‐ to early dynastic material from Abydos (3500–2650 BC), while typical M. africanum signatures were detected in the Middle Kingdom tomb in Thebes‐West (2050–1650 BC). Samples from the New Kingdom to Late Period tombs (1500–500 BC) were characterised as modern M. tuberculosis strains. In concordance with other studies on ancient skeletal and mummified samples, no evidence for the presence of M. bovis was found. These results contradict the theory that M. tuberculosis evolved from M. bovis during domestication, but supports the new scenario that M. tuberculosis probably derived from an ancestral progenitor strain.
