This paper addresses the problem of reactive power dispatch in a power system partitioned into several areas controlled by different transmission system operators. Previous research has shown that nearly optimal performance could be achieved in a time-invariant system by using a specific iterative decentralized control scheme with no information exchange. At each iteration of this scheme, every transmission system operator concurrently schedules its own control settings for the next iteration while representing the neighboring areas with external network equivalents. This paper focuses on some parameter tracking techniques to extend the range of application of the decentralized control scheme to time-varying systems, where the time-varying nature of the system is modeled as a succession of steady-state operating conditions with variation of the load demand. Those new techniques are evaluated in the context of IEEE 118 bus system partitioned into three control areas. [less ▲]

During a case control study undertaken in 2006-2007, a screening and consensus polymerase chain reaction (PCR) was performed to evaluate the potential role of equid herpesviruses (EHV) in several occurrences of respiratory disorders in 661 horses. Of 785 bronchoalveolar or tracheal lavage fluid samples submitted for analysis, 20 were positive for EHV-5 DNA by sequential analysis of the consensus PCR product. Nineteen of those samples were confirmed using a specific EHV-5 PCR. No particular changes in cytological profile could be associated with the detection of EHV-5 in contrast to suggestions in previous reports of natural or experimental respiratory viral infections in horses or ponies. This is the first description of EHV-5 isolation in equine respiratory fluids in Europe, but further investigations are needed to determine the potential pathogenic role of this gammaherpesvirus in the horse.

Piano Key Weirs (PKW) are a new type of weir, showing very good flood release capacities as well as strong economic and structural benefits. However, lacks of understanding persist about the flow conditions on such structures. With the goal to fill some of these lacks, a combined experimental and numerical study has been undertaken at the Laboratory of Structures Hydraulics of the University of Liege. This paper presents the goals and the scientific strategy of this research. The first results of experiments being carried out on a large physical model of PKW are also depicted. These experiments lead to characterization of the flow behavior for low heads and enable to highlight the influence of the crest thickness and the outlet slope on the release capacity. [less ▲]

Steroid hormones act in brain and throughout the body to regulate a variety of functions, including development, reproduction, stress and behavior. Many of these effects of steroid hormones are mediated by their respective receptors, which are members of the steroid/nuclear receptor superfamily of transcriptional activators. A variety of studies in cell lines reveal that nuclear receptor coregulators are critical in modulating steroid receptor-dependent transcription. Thus, in addition to the availability of the hormone and the expression of its receptor, nuclear receptor coregulators are essential for efficient steroid-dependent transactivation of genes. This review will highlight the importance of nuclear receptor coregulators in modulating steroid-dependent gene expression in brain and the regulation of behavior. [less ▲]

L’effet antimicrobien du surnageant de culture neutralisé (SCN) bactéricide issu de Lactococcus lactis CWBI-B1410 d’origine locale, utilisé seul ou en combinaison avec du chlorure de sodium (NaCl) comme conservateurs, a été évalué sur poissons maigre (Pomadasys jubelini), moyennement gras (Polydactylus quadrifilis) et gras (Arius heudeloti)] au Sénégal. Les poissons ont été achetés dans un marché local, éviscérés, lavés avec de l’eau de robinet potable, puis filetés. Cent millilitres de SCN de CWBI-B1410 non salé et salé ont été additionnés dans 100 grammes de filets (concentration finale de NaCl entre 0 et 7 %) dans des bocaux en verre conservés à 10 °C. L’évolution de la flore mésophile totale (FMT) des filets a été comparée à celles de filets traités avec du SCN non salé et salé (concentration finale de NaCl entre 0 et 7 %), issu de L. lactis LMG6890 ne produisant pas de bactériocine. Un niveau de FMT de 106 micro-organismes par gramme (ufc/g) a été considéré comme la fin de la durée de conservation. Le niveau de la flore mésophile totale des filets crus atteignait 5,74 log ufc/g. L’ajout de SCN de CWBI-B1410 dans les filets de poisson maigre réduit la flore mésophile totale de 1 log ufc/g et stabilise la flore pendant 4 jours – correspondant à la durée de conservation de ces filets a` 10 °C, contre 0,5 jour pour le contrôle négatif. L’addition de SCN de CWBIB1410 salé sur les poissons (NaCl, 7 %) réduit davantage la FMT et retarde sa croissance à 10°C, entraînant comme résultat l’augmentation de la durée de conservation de respectivement 12, 7,5 et 8 jours pour le poisson maigre, moyennement gras et gras. Ces résultats suggèrent que cette stratégie peut constituer un moyen convenable d’améliorer la conservation des produits halieutiques tropicaux. [less ▲]

It was shown recently that synovial fibroblast transformation into adipocytes reduced the expression of interleukin-6 (IL-6) and IL-8. However, the synovial fibroblast adipogenesis was inhibited in inflammatory conditions induced by the tumor necrosis factor-alpha (TNF-alpha). Furthermore, adipogenesis is often accompanied by leptin production, a proinflammatory adipokine in rheumatic diseases. In this study, we tested the phytohormone genistein for adipogenic and anti-inflammatory properties on human synovial fibroblasts. Results showed that genistein was able to transform synovial fibroblasts into adipocytes that expressed perilipin-A and produced adiponectin, but not leptin. Furthermore, genistein enhanced glucocorticoid-mediated synovial fibroblast adipogenesis and, in parallel, downregulated glucocorticoid-induced leptin and leptin receptor. Endogenous and TNF-alpha-induced expressions of IL-6, IL-8, p38, p65 and C/EBP-beta were also downregulated by genistein, showing its anti-inflammatory properties. Peroxisome proliferator- activated receptor-gamma (PPAR-gamma) agonist, rosiglitazone, had a synergic effect on genistein-induced whereas the non-active tyrosine kinase inhibitor, daidzein, had a significantly inferior adipogenic activity than genistein. The Janus kinase-2 tyrosine kinase inhibitor, AG 490, mimicked the anti-leptin effect of genistein. These results showed that genistein-induced adipogenesis involves PPAR-gamma induction and tyrosine kinase inhibition. In conclusion, genistein, alone or coupled with glucocorticoids, have both adipogenic and anti-inflammatory effects on synovial fibroblasts. [less ▲]

In the present study we developed an enzymatic approach (through the use of collagenase and dispase) to isolate bovine intestinal epithelial cells. Using this method, freshly isolated jejunocytes could be distinguished from simultaneously isolated colonocytes, as the jejunocytes specifically exhibited the small intestinal peptidase gene transcript, as well as an active alkaline phosphatase. The transformation of both types of cell suspension was performed by retroviral infection, using reproduction-defective viruses bearing the gene coding for the large T antigen of the leukaemia simian virus (SV40). The success of the transfection was demonstrated by (1) a significant increase in cell passage numbers (52-53 vs. 7 passages for non-transfected cells), (2) the detection of both the large T transcript and the large T antigen in transformed cells. Possible contamination and progressive substitution of bovine primocultures by non-bovine lineages available in the laboratory was excluded, as the transformed cells presented a bovine typical karyotype. Most transfected cells kept an epithelial morphology after transformation. They also maintained the expression of FABP and enterocyte specific enzymes (brush-border associated maltase and IAP). However, levels of specific activity of these enzymes were low, suggesting that cell differentiation is not completely achieved under the applied culture conditions. [less ▲]
