The Uyghur (alternatively spelled Uighur) are the largest and titular ethnic group living in the Xinjiang Uyghur Autonomous Region, a vast area in northwestern China of over 1.6 million sq. km. According to the 2010 census Uyghurs make up 45.21 percent of the population of Xinjiang, numbering 8,345,622 people. The Han, the largest ethnic group in China, make up 40.58 percent in the region with 7,489,919. A Turkic-speaking largely Muslim ethnic group, the Uyghurs traditionally inhabited a series of oases around the Taklamakan desert. Their complex origin is evidenced by a rich cultural history that can be traced back to various groups that emerged across the steppes of Mongolia and Central Asia. Uyghur communities are also found in Uzbekistan, Kyrgyzstan, and Kazakhstan, with significant diaspora groups in Australia, the United States, Germany, and Turkey. In the first half of the 20th century, Uyghurs briefly declared two short-lived East Turkestan Republics in 1933 and again in 1944, but the region was brought under the complete control of the Chinese state after the Communist Party (CCP) came to power in 1949. Within China they are considered one of the fifty-five officially recognized ethnic minority groups, who, along with the Han who constitute 92 percent of the population, make up the Chinese nation or Zhonghua Minzu中华民族. However, for many Uyghurs the name “Xinjiang,” which literally translates as “New Territory,” indicates that their homeland is a colony of China, and they prefer the term “East Turkestan.” Nevertheless, many scholars use Xinjiang as a natural term even when they are critical of the position of the Communist Party. In this article both terms are used. In the early years of the People’s Republic of China (PRC) Uyghurs numbered about 80 percent of the population of Xinjiang, but large-scale government-sponsored migration has seen the number of Han in the region rise to almost the same as that of the Uyghur. This has led to an increase in ethnic tensions often caused by competition for scarce resources and a perception that the ruling Communist Party favors the Han. In 2009, a major outbreak of violence in the capital Ürümchi saw hundreds die and many more imprisoned. The years 2013 and 2014 were also crucial turning points with deadly attacks on passengers in train stations in Kunming and Yunnan, bombings in Ürümchi, and a suicide attack in Tiananmen Square in Beijing, all blamed on Uyghur terrorists. Since then the Chinese government has introduced a harsh regime of security clampdowns and mass surveillance, which has significantly increased from 2017 and which, by some accounts, has seen over one million Uyghurs and other Muslim ethnic minorities imprisoned without trial in “reeducation” camps. The Chinese government insist these camps form part of an education and vocational training program designed to improve the lives of Uyghurs and root out “wrong thinking.” Many Uyghurs believe it is part of a long-term project of assimilation of Uyghur identity and culture.

The early years of primary school are important in shaping how children see scientists and science, but researching younger children is known to be difficult. The Draw-A-Scientist Test (DAST), in which students are asked to draw a scientist, has been one of the most popular ways to chart children’s conceptions of scientists and science. However, DAST tends to focus mainly on children’s conceptions about the appearance of scientists. To focus more on children’s conceptions of scientific activities as well as the emotions and attitudes associated with science, the Draw-A-Science-Comic test (DASC) was recently introduced. This study compares three alternative DASC prompts for two age groups of respondents (8- to 10-year-olds and 10- to 13-year-olds). The prompts asking students to draw a comic or a set of pictures produced significantly more sequential storytelling and depictions of science related emotions and attitudes than the prompt asking students to depict a story. The depictions of elements of danger, such as accidents and hazards in the laboratory, were also frequent in drawings with sequential storytelling. A more detailed analysis of the depictions showed that the frequency of elements of danger was closely associated with depictions of activity especially in the field of chemistry. For example, several comics included failed chemical experiments leading to explosions. Although depictions of danger are sometimes interpreted as a negative conception, in the children’s drawings the explosions and overflowing flasks were often seen also as a source of excitement and joy. Based on the result of this study, the use of DASC seems a suitable way for charting children’s conceptions of scientific activities as well as the emotions and attitudes associated with science from the early years of primary education until the beginning of secondary education.

BackgroundCytokine-Induced Killer (CIK) cells are ex vivo expanded T cells with NK cell phenotype. They express both CD3 and CD56 antigens, and exert a potent antitumor activity against a variety of tumors. Several clinical trials demonstrated the safety and the feasibility of CIK cell therapy, with very low side effects and minimal graft-versus-host toxicity. In this study, we developed a GMP-compliant protocol for robust large-scale expansion of CIK cells using G-Rex® gas-permeable static culture flasks.Materials and MethodsCIK cells were obtained by stimulating healthy donor PBMCs with GMP-grade IFN-γ, IL-2 and CD3 mAbs, and were cultured in G-Rex6® or G-Rex®6M well plates. CIK cells in G-Rex6® were split only once at day 7 to reduce cell density, whereas the number of CIK cells culterd in G-Rex®6M was not adjusted. In both culture conditions, fresh IL-2 was provided every 3–4 days. We compared these two culture protocols with the culture in standard flasks. Phenotype was analyzed by flow cytometry and cytotoxicity was assessed against several tumor cell lines by calcein-release assay.ResultsCIK cells cultured in G-Rex6® well plates showed an outstanding cell expansion compared to G-Rex®6M well plates or standard culture flasks, with a 400-fold expansion and a mean of 109 total cells obtained per single well in 14 days, starting from just 2.5 × 106 cells per well. Moreover, the cultures in G-Rex6® were characterized by an higher percentage of CD3+CD56+ cells, as compared to G-Rex®6M or standard culture flasks. Cells cultured in all devices had a comparable expression of NKG2D, NKp30, NKp44, 2B4 receptors. Importantly, CIK cells expanded in G-Rex®6 were as cytotoxic as cells expanded in standard culture flasks. Conversely, CIK cells cultured in G-Rex®6M showed a remarkable reduction of cytotoxicity against tumor cell targets, thus suggesting that cell density during expansion could affect CIK cell activity.ConclusionsWe propose a GMP-compliant protocol for robust large-scale production of CIK cells. G-Rex® system allows to obtain large amounts of CIK cells highly enriched in the CD3+CD56+ subset and endowed with high cytotoxic activity; this can be accomplished with just a single cell culture split at day 7, which dramatically reduces the culture manipulation as compared to the standard culture flasks. Notably, this strategy can be further and easily scalable to produce CIK cells for clinical immunotherapy applications.Disclosure InformationA. Ventura: None. P. Palmerini: None. A.

I. Expansion of the Gaseous and Stellar Components of the GalaxyIf the gaseous component of the Galaxy is expanding as observed by Rougoor and Oort in the centre of the Galaxy and as postulated by Kerr in his early interpretation of spiral structure, the expansion must represent a phenomenon of fundamental importance in the Galaxy which has, in all probability, been operative for a significant fraction of the age of the Galaxy. Presumably, very young stars formed from this gas and having ages less than 1 % of the age of the Galaxy might be expected to retain in their motions the general character of the large-scale expansion of the gas from which they originated.
