Public perceptions of animal experimentation across Europe

The goal of this article is to map out public perceptions of animal experimentation in 28 European countries. Postulating cross-cultural differences, this study mixes country-level variables (from the Eurostat database) and individual-level variables (from Eurobarometer Science and Technology 2010). It is shown that experimentation on animals such as mice is generally accepted in European countries, but perceptions are divided on dogs and monkeys. Between 2005 and 2010, we observe globally a change of approval on dogs and monkeys, with a significant decrease in nine countries. Multilevel analysis results show differences at country level (related to a post-industrialism model) and at individual level (related to gender, age, education, proximity and perceptions of science and the environment). These results may have consequences for public perceptions of science and we call for more cross-cultural research on press coverage of animal research and on the level of public engagement of scientists doing animal research

IFRS introduction and its effect on listed companies in Spain

From the beginning of January 2005 publicly traded companies in the European Union have to comply with the International Financial Reporting Standards (IFRS) for their consolidated accounts, as required by 1606/2002 European Commission Regulation. It had been suggested that the new accounting rules will facilitate not only the process of international harmonization of financial statements, but also efficient performance of financial markets and capital flows worldwide. This study analyzes the first results of IFRS implementation by Spanish non-financial listed companies.

The zebrafish is an animal model in ophthalmic diseases : Fleck corneal dystrophy and Schorderet-Munier syndrome

RAPPORT DE SYNTHÈSE : Pip5k3 : Pip5k3 is a kinase responsible for fleck corneal dystrophy when mutated. It is a well conserved gene that has only been characterized in human and mouse. Characterization of pip5k3 in zebrafish was necessary before using it as a model. The protein is 70 % similar to the human homologue. The full coding sequence encompasses 6303 by and presented four isoforms. They were differentially expressed during development. All the analyzed organs of the adult zebrafish expressed pip5k3. The adult eye expressed pip5k3 in the cornea, lens, ganglion cell layer (GCL), inner nuclear layer (INL) and outer limiting membrane (OLM). During development, pip5k3 was first uniformly expressed before to be restricted to the head region and to the somites. The expression of pip5k3 in the cornea of the larval eye could make possible the study of fleck corneal dystrophy on this animal. NkxS-3 : NKXS-3 is a transcription factor responsible for a new oculo-auricular syndrome in human when mutated. This recessive disorder is characterized by defects in ear lobule and multiple defects in eye, including microphthalmia and cataract. During development, the zebrafish expressed nkx5-3 in the lens, in the anterior retina and in otic vesicles. Knockdown experiments partially phenocopied the human disease. Microphthalmia and cataract were reproduced, but zebrafish showed also defects in the cartilage of the jaw associated with a microcephaly and fins abnormalities. The retinal cell differentiation was delayed, possibly linked with the delayed expression of at`h5 and crx also observed in morphants. Shh, a regulator of ath5, was normally expressed in morphant. Overexpression of nkx5-3 lead to an anophthalmia, suggesting a role at the early organogenesis of the eye. All the phenotypes observed in morphants and embryos overexpressing nkx5-3 suggest a potential involvement of the FGF and hedgehog signaling pathways.

Necrophagous diptera associated with wild animal carcasses in southern Brazil

Necrophagous Diptera associated with wild animal carcasses in southern Brazil. The aim of this study was to acquire a better knowledge concerning the diversity of necrophagous Diptera that develop on wild animal carcasses. For this purpose, the decomposition of six wild animal carcasses was observed in order to collect and identify the main species of necrophagous flies associated with the decomposition process. The carcasses were found on highways near the cities of Pelotas and Capão do Leão in the initial stage of decomposition, with no significant injuries or prior larval activity. Four wild animal models were represented in this study: two specimens of Didelphis albiventris Lund, 1840; two Tupinambis merianae Linnaeus, 1758; one Nothura maculosa Temminck, 1815; and one Cerdocyon thous Linnaeus, 1766. A total of 16,242 flies from 14 species were reared in the laboratory, where Muscidae presented the greatest diversity of necrophagous species. Overall, (i) carcasses with larger biomass developed a higher abundance of flies and (ii) the necrophagous community was dominated by Calliphoridae, two patterns that were predicted from published literature; and (iii) the highest diversity was observed on the smaller carcasses exposed to the lowest temperatures, a pattern that may have been caused by the absence of the generalist predator Chrysomya albiceps (Wiedemann, 1819). (iv) An UPGMA analysis revealed a similar pattern of clusters of fly communities, where the same species were structuring the groupings.
