Tuberculosis among Iron Age individuals from Tyva,South Siberia: palaeopathological and biomolecular findings

The study focuses on the evidence for tuberculosis apparent in an Iron Age population recovered from the cemetery of Aymyrlyg, Tyva (Tuva), South Siberia. A recent wholly molecular study of five of the cases confirmed the presence of Mycobacterium tuberculosis (MTB) complex DNA in four of the individuals. In all cases the disease was caused by strains of Mycobacterium bovis rather than Mycobacterium tuberculosis and represents the first positive identification of the bovine form of the disease in archaeological human remains. Details of the palaeopathological characteristics of the cases are provided in the current paper, while the molecular observations are extended to include a quantitative evaluation of the surviving mycobacterial DNA using real-time PCR. The observation that bovine tuberculosis was the pathogen responsible is discussed in terms of current understanding of the evolution of the MTB complex as well as the implications for future ancient DNA studies in this area.     

晚清东北商埠格局变迁研究

晚清东北商埠格局历经萌芽、雏形、形成、发展四个阶段的变迁进程。此格局在变迁过程中呈现出商埠地域分布以沿交通线为主、类型的多样性及发展的不平衡性等特点。晚清东北商埠格局的变迁,对区域社会经济产生了深远影响：从晚清东北开埠进程看,东北开放区域是伴随着列强侵略的步步深入而渐次增大的;随着东北对外开放空间的拓延,近代化因素透过商埠窗口逐渐渗入东北社会,商埠发展客观上推动了东北区域的近代化路程。     

The Regional Dimension of Russian Oil Production: Is a Sustained Recovery in Prospect?

An American geographer and prominent authority on oil and natural gas industries and resources of Russia and other former republics of the Soviet Union presents a region-byregion account of Russia's oil production, tracing in considerable detail developments up to September 2006. The account, based on systematic and frequent field investigations since the early 1990s as well as interviews with key industry executives, covers reserves, output trends, ownership, investments, pipelines, and a variety of economic factors including exports to China. Addressing the question of whether sustained production recovery is possible, the author presents American and Russian scenarios projecting oil output through the year 2020.

Iron Age pastoral nomadism and agriculture in the eastern Eurasian steppe: implications from dental palaeopathology and stable carbon and nitrogen isotopes

Iron Age societies of the eastern Eurasian steppe are traditionally viewed as nomadic pastoralists. However, recent archaeological and anthropological research in Kazakhstan has reminded us that pastoralist economies can be highly complex and involve agriculture. This paper explores the nature of the pastoralist economies in two Early Iron Age populations from the burial grounds of Ai-Dai and Aymyrlyg in Southern Siberia. These populations represent two cultural groups of the Scythian World – the Tagar Culture of the Minusinsk Basin and the Uyuk Culture of Tuva. Analysis of dental palaeopathology and carbon and nitrogen stable isotopes suggests that domesticated cereals, particularly millet, and fish formed a major component of the diet of both groups. The findings contribute to the emerging picture of the nuances of Early Iron Age subsistence strategies on the eastern steppe.
