Induced pluripotent stem cells (iPSC) have been generated from somatic cells by introducing reprogramming factors. Integration of foreign genes into the host genome is a technical hurdle for the clinical application. Here, we show that Sendai virus (SeV), an RNA virus and carries no risk of altering host genome, is an efficient solution for generating safe iPSC. Sendai-viral human iPSC expressed pluripotency genes, showed demethylation characteristic of reprogrammed cells. SeV-derived transgenes were decreased during cell division. Moreover, viruses were able to be easily removed by antibody-mediated negative selection utilizing cell surface marker HN that is expressed on SeV-infected cells. Viral-free iPSC differentiated to mature cells of the three embryonic germ layers in vivo and in vitro including beating cardiomyocytes, neurons, bone and pancreatic cells. Our data demonstrated that highly-efficient, non-integrating SeV-based vector system provides a critical solution for reprogramming somatic cells and will accelerate the clinical application.(Communicated by Kumao TOYOSHIMA, M.J.A.)

Of the many works of Earl Miner, former President of the International Comparative Literature Association, who died in 2004, the most important is Monkeyʼs Straw Raincoat (1981). It is a meticulous English translation of the whole of the Sarumino , a consummate anthology of haiku and linked poetry (haikai-renga) by Basho and his school, accompanied by Minerʼs extensive introduction and detailed interpretations. Typically, a linked poem comprises thirty-six verses, which are composed at one sitting by three or more persons taking turns. “Long” verses of seventeen syllables alternate with “short” verses of fourteen syllables. The initial long verse, called hokku, should be a complete poem in its own right, with mandatory season-word and cutting-word. Often composed and appreciated by itself, hokku came to be called haiku in the nineteenth century, thus exempt from its original role as “starting” verse. The ensuing thirty-five verses, although semantically autonomous, cannot stand alone as poems. Each of them makes “poetic” sense only in conjunction with adjacent verses, either preceding or following it. (View PDF for the rest of the abstract.)

This review article deals with a new element ‘nipponium’ reported by Masataka Ogawa in 1908, and with its scientific and science historical background. Ogawa positioned nipponium between molybdenum and ruthenium in the periodic table. From a modern chemical viewpoint, however, nipponium is ascribable to the element with Z=75, namely rhenium, which was unknown in 1908. The reasons for this corrected assignment of nipponium are (1) its optical spectra, (2) its atomic weight when corrected, (3) its relative abundance in molybdenite, the same being true with rhenium. Recently some important evidence was found among the Ogawa’s personal collection preserved by his family. Deciphering the X-ray spectra revealed that the measured spectra of the nipponium sample that Ogawa brought from University College, London clearly showed the presence of the element 75 (rhenium). Thus was resolved the mysterious story of nipponium, which had continued for almost a century. It is concluded that nipponium was identical to rhenium.(Communicated by Toshimitsu YAMAZAKI, M.J.A.)

This report is based on case studies of village religious-ceremony organization in the New Territories (formerly, Xin’an Prefecture), Hong Kong. Comparisons are drawn between similar groups in China and Japan. Focus is on the structure of large-scale religious ceremonies in the New Territories. Every five or ten years, eighty percent of the villages carry out ceremonies that can extend for a week. They are called ‘Great Peace Purification Sacrifices’ 太平清醮. Entire villages participate, groups of Daoist priests and troupes of actors are invited, and activities are performed day and night for anywhere from three days (and four nights) to six days (and seven nights). To console the spirits and gods, courtesies are extended, offerings presented, and plays performed on their behalf. A distinguishing feature of the ‘Great Peace Purification Sacrifice’ is the way that the names of all clan members are repeatedly read aloud, one by one. At the shortest of ceremonies (three days and four nights), the recitation can be repeated a halfdozen times or more. The sequence is as follows: ‘First Submission to the Gods’: For the first day, during the third lunar month, certain formalities are carried out in preparation for the ceremonies proper. Facing away from the village temple and directing themselves to the gods above, Daoist priests read aloud the names of clan members from the entire village, calling out the names that have been recorded for submission: heads of households, their wives and concubines, unmarried brothers and sisters, married sons, daughters-in-law, unmarried children, grandsons and their wives, unmarried grandsons, granddaughters, great grandsons and their wives, and so on. But women’s first names are neither recorded nor read aloud. As there are cases of more than two hundred names, and since the calling out of the names can be lengthy, the task of reading aloud is divided among the priests. ‘Second Submission’: On the second preparatory day, in the middle of the eighth lunar month, the same formalities are carried out. ‘Third Submission’: The beginning of the tenth lunar month marks the first day of the ceremonies proper. Prior to the performance of sacrifices, clan names are read aloud before the temple a third time, again by multiple priests. ‘Opening Announcement’: Over the beginning of the same month, the list of village members is posted on the public-square bulletin board. Inscribed in black calligraphy on large red paper, it can be as wide as six feet. Daoist priests again divide up the task of reading aloud the names. ‘Inviting the Gods’: On a night during the first ten days of the month, after they invite the highest gods from heaven, one of the Daoist priests reads aloud the roster of villager names. ‘Begging Pardon’: On the last day of the religious ceremony, again during the first third of the tenth lunar month, a Daoist priest reads aloud the list of villager names inscribed in vermilion ink on yellow paper three-feet wide. The document reports to heaven that villagers, having unintentionally committed sins, beg the gods’ pardon. In addition, the head-worshipper of the village often carries the community roster and accompanies the Daoist priests while the latter perform prayer ceremonies and make a ‘circuit’ to pay respects to the gods. Although villagers do not read aloud names on the roster, they always have clearly in mind that everyone in the village is participating. (View PDF for the rest of the abstract.)

Since the 19th century the state has been used diachronically as the term signifying the political society. But until the end of the 18th century the term civitas also had been used at least in the academic world. Originally civitas was the word meaning Roman city-state, interchangeable with populus or res publica, and was taken synonym of Greek polis. These city-states were communities of their citizens above all. But koinonia politike and societas civilis were provided with their governmental systems at the same time.On the other hand the new term stato which came to be used in the 15th century Italy originally meant the political power, the power holder or his governing instrument. Jean Bodin tried to make the state include also all the governed, and at the same time, he discriminated the city from the state which came to have sovereignty. Bodin's theory therefore contributed so much to establish the modern absolutist state, which included all estates and various corporations under the sovereign power, but was after all the patrimony of some dynasty.The social contract theory which took many conceptual weapons from the classical terminology constructed the new image of the political society upon the model of the voluntary association. Being provided with the new notion of the nation, French Revolution established the nation state which excluded all corps intermédiaires, and left the model“one nation, one language, one state”. It is well known that the people called each other with the title citoyen.But even in France the term of civil began to cease to be interchangeable with politique as the code civil exemplified. In Britain The Wealth of Nations presented a system of material reproduction of the society, independent of the governmental power. On the other hand individed Germany the state had been the objective to be achieved. After his vigorous study of British political economy, Hegel presented his system of Sittlichkeit composed of family, civil society and the state. His bürgerliche Gesellschaft could not be self-contained and should be completed by the state. Now Bürger meant only bourgeois, not citoyen, and the new term Staatsbürger came to be inevitable.In the beginning of the 20th century, only half of the global population had their citizenships of some state. Owing to the principle of national self-determination, many new states emerged in Europe after the 1st World War. And the de-colonization after the 2nd World War and the dissolution of Soviet Union brought new states to many men and women. Nearly all global population would have their citizenships in the end of this century. But this universalization of the state would be its nominalization at the same time, not only in the developping countries, but also in the developped ones. The pursuit of their identities of various groups and the borderless condition of the survival of mankind urged us reconsider the self-evidence of the nation state. We had better, I believe, cease applying the concept of the state diachronically and to put it in a historical perspective of ideas.

Mortality decline, the first phase of the demographic transition, has long been considered a transition triggered by the industrial revolution. This paper is an attempt to question this traditional view, putting forward a set of arguments, first, that the mortality transition was a longer process than conventionally thought, starting a century earlier than the onset of modern economic growth, and second, that a substantial increase in the level of life expectancy at birth, a summary measure of age-specific mortality rates, was indeed a prerequisite of modern economic growth and, hence, of fertility transition, the second phase of the demographic transition. The article begins with a brief overview of the historiography in demography, epidemiology and medical history. Much effort has been made to account for the historical process of mortality decline, and from the past debates there are a couple of lessons learned. One is that while medical progress can no longer explain the early decline in mortality, public health measures are likely to have played an important part. The other is that there is not much evidence to support the claim that economic development led to reductions in death rates. The demographer Samuel Preston demonstrated, by assembling country data on both life expectancy at birth and national income per capita for the 1930s and the 1960s, that the curve representing the relationship between the two factors (called the Preston curve) shifted significantly upwards between the two time-periods. According to his analysis of inter-temporal shifts, income growth per se explained only 16 per cent of the rise in longevity while a bundle of other factors accounted for 84 per cent; and the only variable that had a statistically significant correlation with the gain in life expectancy was the initial level of income – though, contrary to the expectation, its sign was negative. There are also suggestions by historians that in earlier stages where epidemics were more frequent nutrition is unlikely to have been a decisive factor to bring the level of mortality down. According to a recent synthesis in evolutionary biology of pathogens, there is a trade-off between their lethality and transmission potential. Diseases with high lethality, such as plague and smallpox, do not usually depend on their human host for transmission, whereas pathogens that are transmitted person to person but cannot persist outside the host are under strong selective pressure against high host lethality. Based on this conceptual framework as well as stylised facts from English historical demography, Romola Davenport of the Cambridge Group for the History of Population and Social Structure argues that infectious diseases reduced or eliminated in periods before 1870 are those of the first type, while childhood infections and other diseases that lingered on into the first half of the twentieth century are of the second type. Indeed, the Cambridge Group’s path-breaking work on the historical demography of England, c.1540-1870, reveals that from the late seventeenth century onwards adult, child and neonatal mortality rates started to decline but the post-neonatal mortality rate did not. Over the long run, in other words, deaths from pestilence and famine were reduced, thanks to early modern economic growth or the implementation of rudimentary measures in public health by government authorities, or both, while exposure to infection was on the rise, suggesting that the long-term decline of mortality started well before the industrial revolution, but the process became prolonged as industrialisation and urbanisation progressed.
