Fluoride does not induce DNA breakage in Chinese hamster ovary cells in vitro.

Fluoride has been widely used in dentistry because it is a specific and effective caries prophylactic agent. However, excess fluoride may represent a hazard to human health, especially by causing injury to genetic material. Genotoxicity tests represent an important part of cancer research to assess the risk of potential carcinogens. In the current study, the potential DNA damage associated with exposure to fluoride was assessed by the single cell gel (comet) assay in vitro. Chinese hamster ovary cells were exposed to sodium fluoride (NaF) at final concentration ranging from 7 to 100 micro/ml for 3 h, at 37 dgrees C. The results pointed out that NaF in all concentrations tested did not contribute to DNA damage as depicted by the mean tail moment and tail intensity. These findings are clinically important since they represent an important contribution to a correct evaluation of the potential health risk associated with the exposure to dental agents.

Relevance of Chinese goose (Anser cygnoides) in experimental epidemiology of Newcastle disease

This study aimed to characterize the true epidemiological role played by the Chinese goose (Anser cygnoides) as a potential source of infection by the Newcastle disease virus (NDV). For this, Specific-Pathogen-Free chicks (SPF) were used and were housed with Chinese geese that had been inoculated with a pathogenic strain (velogenic viscerotropic, strain São João do Meriti) of NDV (DIE50=108.15/0.1 mL) pathogenic to chickens, by the ocular-nasal route. Each group was composed of 6 SPF Leghorn chicks and 3 geese. At 6 days (Group I) and 14 days (Group II) after inoculation of the Chinese geese with NDV, SPF chicks were put into direct contact with each goose group. Cloacal swabs were collected from both species (Chinese geese and SPF chicks) 6, 10 and 20 days after challenge to genome viral excretion by Reverse Transcription Polymerase Chain Reaction (RT-PCR). Chinese geese did not demonstrate any clinical signs of Newcastle disease (ND). They were refractory to the clinical disease with the NDV. However, NDV genome was detected 20 days after challenge. Therefore, NDV carrier status was demonstrated by Chinese geese. Moreover, 100% of SPF chicks housed with the infected Chinese geese had died by 6 (Group I) and 14 days (Group II) after challenge. Thus, the transmission of the pathogenic virus from the Chinese geese to cohabiting SPF chicks was evident within 20 days of the experimental infection. This reveals the epidemiological importance of Chinese geese as a potential transmitter of NDV infection to other commercial birds that could be raised in close proximity.

Chinese foreign direct investment in Latin America and the Caribbean: China-Latin America cross-council taskforce. Working document

Although Chinese corporations were relatively unknown in Latin America until a few years ago, their direct investments in the region have averaged about US$10 billion per year since 2010. Their presence and economic leverage have become very significant in many industries and countries of the region, but their motivation, strategy and procedures are not always well understood by Latin America’s governments, businesses and civil society. Similarly, Chinese companies still need to gain a better understanding of Latin America’s business environment and opportunities. This working document is an input for discussing the future of Chinese foreign direct investment (FDI) in Latin America at the China - Latin America cross-council taskforce at the Summit on the Global Agenda, to be held under the auspices of the World Economic Forum (WEF), in Abu Dhabi on 18-20 November 2013. It was prepared jointly by Taotao Chen, Professor of Finance of the School of Economics and Management of Tsinghua University in China and member of the WEF Global Agenda Council on China, and by Miguel Pérez Ludeña, Economic Affairs Officer at the Economic Commission for Latin America and the Caribbean (ECLAC), under the supervision of Alicia Bárcena, Executive Secretary of ECLAC and Vice-Chair of the WEF Global Agenda Council on Latin America.

The People’s Republic of China and Latin America: the impact of Chinese economic growth on Latin American exports

The role of the People’s Republic of China in the world economy has grown substantially in recent decades, turning it into a strategic foreign trading partner for much of Latin America. Bilateral trade between the region and China totalled US$ 120 billion in 2009. This study analyses the income elasticity of the region’s exports to the country. The findings show that, assuming real gross domestic product (gdp) growth in China of about 7% a year, the value of Latin American exports to China (at 2005 prices) can be expected to increase by an average of about 10% a year between 2014 and 2019. In a more conservative scenario of 4.5% average annual growth in the Chinese economy over the period, exports would rise by about 7% a year.

Aboutness in Fiction: Methodological Perspectives for Knowledge Organization

The subject analysis of narrative texts of fiction is complex; the methodological model of identification of concepts as elaborated for scientific texts is not applicable to fiction. It is proposed here that theoretical and methodological use of the Generative Trajectory of Meaning postulated by Greimas may contribute to the identification of aboutness in narrative texts of fiction.
