La description par Sāyaņa (commentateur de nombreuses œuvres relevant du Veda, 1296-1387) des préparatifs du sacrifice védique aux nouvelle et pleine lunes permet de saisir la méthode pour sacraliser actes et paroles profanes. Ces préparatifs commencent la veille du rite quand on cueille une branche grâce auquel on écartera les veaux des vaches qui fournissent le lait d’offrande. Puis vient la description minutieuse des gestes et des versets qui accompagnent la fabrication de la jonchée et celle du gâteau. On n’oublie pas d’amadouer ou d’expulser les forces démoniaques qui peuvent perturber la cérémonie. On construit l’autel (vedi) et on purifie les cuillers servant aux puisées de lait. L’un des officiants lie la ceinture de l’épouse du patron du sacrifice de manière à ce qu’elle participe avec lui au rite. Avec le beurre fondu qu’on a au préalable miré, on asperge matières oblatoires et bûches. Vient ensuite l’oblation dans le feu du lait mentionné ci-avant mais cette partie de la cérémonie n’est pas décrite ici. Le lecteur se rend compte, au fil des pages, que la condition profane des êtres et des choses se sacralise via des actes comme des attouchements, des essuyages, des effleurements, des aspersions, des filtrages et des échauffements accompagnés de versets au Ŗgveda etc. Contribuent aussi à cette sacralisation des instruments comme une côte de cheval pour couper de l’herbe ou les multiples cuillers sacrificielles. Les dieux ne peuvent pas sacrifier, parce qu’ils n’ont personne au dessus d’eux à qui faire une offrande .Les animaux ne le peuvent pas non plus, car ils ne peuvent exécuter des rites et n’en désirent pas les fruits. L’homme est donc le seul être capable de sacrifier, mais il doit se conformer à la méthode enseignée par la révélation védique. [less ▲]

This paper investigates the effect of market-wide liquidity on optimal portfolio allocations across US equity portfolios sorted by size and book-to-market characteristics. In particular, we consider a single-period investor with a relative risk aversion of 5, and use the nonparametric approach of Brandt (1999) to directly express optimal portfolio weights as functions of market-wide liquidity innovations. We find, first, that the effect of market-wide liquidity is a decreasing function of investment horizon. Second, this effect is stronger in allocations in the small stock portfolio and gets weaker as we move towards the large stock portfolio. Third, conditional allocations in risky asset(s) decrease and exhibit shifts towards more liquid and less risky assets as market-wide liquidity worsens. Overall, our results show that allocations based on market-wide liquidity as a signal capture many phenomena that have been identified by researchers in the US market, such as the so-called “flight-to-safety”, flight-to-quality” and “flight-to-liquidity” episodes. Furthermore, in an out-of-sample test, results demonstrate the superior performance of a strategy based on market-wide liquidity compared to a benchmark strategy. [less ▲]

In some vertebrate species, type I interferon(IFN)-induced Mx gene expression has been shown to confer resistance to some single-stranded RNA (ssRNA) viruses in vitro. Because the bovine species is subject to an exceptionally wide array of infections caused by such viruses, it is anticipated that an antiviral allele should have been retained by evolution at the bovine Mx locus. The identification of such allele may help in evaluating the real significance of the Mx genotype for disease resistance in vivo, in deciphering host-virus molecular interactions involved, or in improving innate disease resistance of livestock through marker-assisted selection. We validated a double transgenic Vero cell clone in which the bovine Mx1 reference allele is placed under control of the human cytomegalovirus (CMV) enhancer-promoter sequence containing elements from the bacterial tetracycline resistance operon to regulate transcription. In the selected clone, transgene repression was very tight, and derepression by doxycycline led to homogeneous 48-h duration expression of physiologic levels of bovine Mx1. Expression of the transgene caused a dramatic decrease in cytopathic efficiency and a 500-5000-fold yield reduction of the Indiana and New Jersey serotypes of vesicular stomatitis virus (VSV). To our knowledge, the transgenic clone developed here is the first ever reported that allows conditional expression of an Mx protein, thus providing a valuable tool for studying functions of Mx proteins in general and that of bovine Mx1 in particular. This latter may henceforward be included in the group of Mx proteins with authenticated anti-VSV activity, which offers new research avenues into the field of host-virus interactions. [less ▲]

This paper examines the statistical behavior of daily stock returns in several Pacific-Basin stock exchanges, which have grown tremendously in recent years. Empirical evidence reveals that return-generating models which empirically fit the data are processes with conditional heteroscedastic innovations. Particularly, the generalized autoregressive conditional heteroscedastic GARCH(1,1) process turns out to be the best in most cases. [less ▲]

BACKGROUND INFORMATION: Nucleolin is a major nucleolar protein which is highly expressed in rapidly dividing cells and cancer cell lines. This protein is claimed to be multifunctional and could play a role in rRNA (ribosomal RNA) synthesis, as well as in cell division or response to cellular stresses. Therefore, how nucleolin influences cell proliferation remained elusive so far. RESULTS: We have generated conditional nucleolin-knockout cells using the chicken B lymphocyte cell line DT40. Our results indicate that nucleolin is absolutely required for the proliferation and for the survival of these cells. Depletion of nucleolin drastically inhibits rDNA (ribosomal DNA) transcription while only slightly affecting pre-rRNA processing. This inhibition is accompanied by modifications of the shape and the structure of the nucleolus. The analysis of mutants of nucleolin, which lack two or three RNA-binding domains, shows that these domains harbour redundant functions and that nucleolin's roles in transcription, rRNA maturation and nucleolar shape can be partially uncoupled. CONCLUSIONS: The function of nucleolin in ribosomal synthesis could account for its effect on cell division and survival, but this vital role does not seem to be linked to sequence-specific RNA binding.

The aims of the study were to test whether drug dose is positively related to the magnitude of the conditioned response following sensitization to the behavioural effects of cocaine and to investigate the relationship between the conditioned response and cocaine-induced sensitization. Male mice (C57BL/6J) were first injected over seven successive days with either saline or cocaine at 2.5, 5, 10 or 20 mg/kg s.c., in the testing room. On the test day, 24 h after the last injection, mice from all conditions were challenged with saline in the testing room to test for conditioned cocaine effects. Mice were video-recorded and various behaviours were later scored using a time-sampling technique. Cocaine-elicited orofacial stereotypy was significantly sensitized at the two highest doses and dose-dependently conditioned at the three highest doses. Cocaine-increased locomotion was sensitized at the three highest doses and significantly conditioned at 10 and 20 mg/kg. Cocaine-increased sniffing did not change over pretreatment at any dose, and was conditioned only at 10 mg/kg. Cocaine-decreased immobility also did not change over pretreatment at any dose, but was conditioned at 10 and 20 mg/kg. Concomitantly, rearing was reduced by cocaine at 10 and 20 mg/kg, without sensitization being induced, and it was reduced under saline challenge after 5 mg/kg cocaine, while cocaine-decreased grooming was sensitized at the three highest doses and conditioned at 10 and 20 mg/kg cocaine. There was a positive relation between the size of the conditioned response for orofacial stereotypy and the magnitude of the unconditioned stimulus (the doses), a result conforming to the Pavlovian account of the placebo effect. This could also be concluded from considering the behaviour patterns as components of a unique placebo effect (hyperkinetic syndrome), since orofacial stereotypy, very apparent at 20 mg/kg cocaine, interfered at that dose with the full-blown expression of locomotion and sniffing, both yielding (approximately) inverted U-shaped dose-effect curves. However, no correlation was found between the magnitude of the conditioned response and the amplitude of sensitization (the difference between the initial unconditioned non-sensitized response and the last unconditioned sensitized response), a finding which indicates that conditioned responding does not participate in the generation of the sensitized effects, contrary to the 'excitatory conditioning model of contextual sensitization' [less ▲]
