Méthodes de dénombrement des bactéries du rumen de mouton

Afin de mieux comprendre l’écosystème rumen par l’étude de l’évolution du nombre des bactéries totales et celui de certaines flores spécifiques, deux techniques de quantification sur filtre sont proposées.(i) L'acridine orange est un fluorochrome qui se fixe sur les acides nucléiques de toutes les bactéries et permet de les colorer en vue de les dénombrer. Parallèlement, les cellules viables ont été dénombrées par culture en milieu solide pour comparaison. Les nombres obtenus par la technique de coloration ont été supérieurs à ceux des cellules viables d’une unité logarithmique, du fait que la première technique tient compte à la fois des cellules vivantes et mortes. (ii) L'immunofluorescence indirecte, basée sur des anticorps polyclonaux dirigés contre dix souches naturellement majoritaires du rumen de mouton, a été également utilisée pour le dénombrement de ces souches en fonction du temps. Les résultats obtenus montrent une bonne spécificité des anticorps et un suivi efficace des différentes souches utilisées

Acute toxicity of essential oils of two Moroccan endemic species: Thymus broussonetii and Thymus leptobotrys

Abstract Thymus species essential oils are widely used in aromatherapy to treat several ailments. However, there is no report on their safety. In this study, we propose to investigate the acute toxicity of T. leptobotrys and T. broussonetii essential oils. These two species were selected on the basis of their frequency of medicinal use and commercial importance. Chemical analysis of these two species essential oil revealed that thymol, borneol, carvacrol and p-cymene were the main chemical constituents in T. broussonetii, whereas the essential oil of T. leptobotrys contains carvacrol (98 %) as the major component. In the acute toxicity assay, the animals showed no stereotypical symptoms associated with toxicity such as convulsion, ataxy, diarrhoea or increased diuresis. The calculated median lethal dose (LD 50 ) was estimated at 4.47 g/kg for T. broussonetii and 2.66 g/kg for T. leptobotrys

Anti-tumor properties of black seed (Nigella Sativa)extract

Abstract The objective of the present study was to evaluate the in vitro and in vivo anti-cancer effect of Nigella sativa L. seed extracts. The essential oil (IC 50 = 0.6%, v/v) and ethyl acetate (IC 50 = 0.75%) extracts were more cytotoxic against the P815 cell line than the butanol extract (IC 50 = 2%). Similar results were obtained with the Vero cell line. Although all extracts had a comparable cytotoxic effect against the ICO1 cell line, with IC 50 values ranging from 0.2 to 0.26% (v/v), tests on the BSR cell line revealed a high cytotoxic effect of the ethyl acetate extract (IC 50 = 0.2%) compared to the essential oil (IC 50 = 1.2%). These data show that the cytotoxicity of each extract depends on the tumor cell type. In vivo, using the DBA2/P815 (H 2 d ) mouse model, our results clearly showed that the injection of the essential oil into the tumor site significantly inhibited solid tumor development. Indeed, on the 30th day of treatment, the tumor volume of the control animals was 2.5 ± 0.6 cm 3 , whereas the tumor volumes of the essential oil-treated animals were 0.22 ± 0.1 and 0.16 ± 0.1 cm 3 when the animals were injected with 30 µL (28.5 mg)/mouse and 50 µL (47.5 mg)/mouse per 48 h (six times), respectively. Interestingly, the administration of the essential oil into the tumor site inhibited the incidence of liver metastasis development and improved mouse survival

Worst-Case Fair Bin Sort Queuing (WBSQ): An O(1) Worst-Case Fair Scheduler

Abstract—The design of packet schedulers involves a tradeoff between implementation complexity, on one hand, and delay and fairness guarantees, on the other. In this paper, we present worst-case fair bin sort queuing (WBSQ), a new scheduler that has good worst-case fairness and delay properties, yet has low complexity and is amenable to simple hardware implementation. WBSQ achieves this performance by combining features of BSFQ and WF 2 Q+. We establish the worst-case fairness and delay properties of WBSQ through both analysis and simulation. I

Processus réactionnels accompagnant la chimisorption du dioxyde de carbone sur un catalyseur au nickel en relation avec la réaction de méthanation

Les expériences de thermodésorption (TPD) du CO2 pré-adsorbé sur un catalyseur de nickel dispersé sur silice permettent de révéler l'influence de l'hétérogénéité de la surface sur les processus accompagnant la chimisorption du dioxyde de carbone ainsi que sur ceux susceptibles de se dérouler ultérieurement (ré-association de COads avec Oads, dismutation de COads...) La méthanation de COads se produit de façon semblable sur chaque fraction de surface. La dissociation de CO n'apparaît pas pouvoir se faire facilement, mais est facilitée par l'action d'une autre espèce comme Hads ou COads (dismutation). Ces expériences permettent l'interprétation de certaines particularités cinétiques de l'hydrogénation de chaque oxyde de carbone
