Effect of interferon on the development of Trypanosoma cruzi in tissue culture "Vero" cells

Results are presented on the effects of interferon on the intracellular stages of T. cruzi in tissue culture "Vero" cells. Interferon was obtained by infecting monolayers of human amniotic cells with inactivated Newcastle disease virus. Interferon has not affected the cell infection by T. cruzi culture infective stages and neither has it prevented the transformation of amastigote into trypomastigote stages.

Differential effect of culture epimastigotes and blood-form Trypamastigotes on normal mouse splenocyte responsiveness to mitogens

Blood form trypomastigotes of the Y strain of T. cruzi, produced a strong inhibition of the blastogenic response to T and B cell mitogens, of the C3H/He, C57BLand BALB/cJ strains of mice, while culture epimastigotes of the Y strain kept in a medium that allows parasite growth at 26°. 30° and 37°C produced a strong stimulatory effect that was even higher than the effect of the mitogens alone. Both the inhibitory or the stimulatory effects were dose-dependent. The stimulatory effect of epimastigotes was also temperature-dependent producing increasedstimulation indexes as the temperature of parasite cultures was raised. Metabolically active,living parasites seemed to be necessary for an improved lymphocyte stimulation suggesting a potential role of secreted metabolites as polyclonal activators of mouse lymphocytes.

Influence de deux milieux séquentiels pour la culture d'embryons sur la production d'hormone gonadotrophine chorionique et de progestérone par des cellules JEG-3 et BeWo [Effects of different embryo development media on hCG and progesterone release by JEG-3 and BeWo cells]

Current in vitro fertilisation (IVF) practice requires synchronisation between the¦environment of cultured oocytes and embryos and the surroundings to what they would have¦been exposed to in vivo. Commercial, sequential media follow this requirement but their exact¦composition is not available. We have compared two widely used IVF culture media systems using¦the two choriocarcinoma cell lines JEG-3 and BeWo. The two hormones hCG and progesterone¦were determined in the culture supernatants as endpoints. In both cell lines, but in a more¦pronounced way in JEG-3, progesterone rather than hCG production was stimulated, and a¦higher hormone release was observed in the fertilisation than in the cleavage media. Differences¦between manufacturers were small and did not favour one system over the other. We conclude¦that both sequential media systems can be equally well used in current IVF laboratory practice.¦© 2012 Elsevier Masson SAS. All rights reserved.

Jatobal virus antigenic characterization by ELISA and neutralization test using EIA as indicator, on tissue culture

A virus antigenic characterization methodology using an indirect method of antibody detection ELISA with virus-infected cultured cells as antigen and a micro virus neutralisation test using EIA (NT-EIA) as an aid to reading were used for antigenic characterization of Jatobal (BeAn 423380). Jatobal virus was characterized as a Bunyaviridae, Bunyavirus genus, Simbu serogroup virus. ELISA using infected cultured cells as antigen is a sensitive and reliable method for identification of viruses and has many advantages over conventional antibody capture ELISA's and other tests: it eliminates solid phase coating with virus and laborious antigen preparation; it permits screening of large numbers of virus antisera faster and more easily than by CF, HAI, or plaque reduction NT. ELISA and NT using EIA as an aid to reading can be applicable to viruses which do not produce cytopathogenic effect. Both techniques are applicable to identification of viruses which grow in mosquito cells.

Entrepreneurial intention, cognitive social capital and culture: empirical anaylisis for Spain and Taiwan

The main purpose of this paper is building a research model to integrate the socioeconomic concept of social capital within intentional models of new firm creation. Nevertheless, some researchers have found cultural differences between countries and regions to have an effect on economic development. Therefore, a second objective of this study is exploring whether those cultural differences affect entrepreneurial cognitions. Research design and methodology: Two samples of last year university students from Spain and Taiwan are studied through an Entrepreneurial Intention Questionnaire (EIQ). Structural equation models (Partial Least Squares) are used to test the hypotheses. The possible existence of differences between both sub-samples is also empirically explored through a multigroup analysis. Main outcomes and results: The proposed model explains 54.5% of the variance in entrepreneurial intention. Besides, there are some significant differences between both subsamples that could be attributed to cultural diversity. Conclusions: This paper has shown the relevance of cognitive social capital in shaping individuals’ entrepreneurial intentions across different countries. Furthermore, it suggests that national culture could be shaping entrepreneurial perceptions, but not cognitive social capital. Therefore, both cognitive social capital and culture (made up essentially of values and beliefs), may act together to reinforce the entrepreneurial intention.
