A new ceramide, droogmansiamide (1), was isolated from methanolic extract of roots wood of Erythrina droogmansiana, with eight known compounds namely 3-(3’,4’-methylenedioxyphenyl)-2,3-epoxypropanol (2), erythrinasinate A (3), erythrinasinate B (4), abyssinone-IV-4'-methylether (5), erythrabyssin (6), phaseollidin (7), 4’-methoxylicoflavanone (8) and abyssinone-V-4'-methylether (9) respectively from methanolic extract of roots wood and EtOAc extract of roots bark of the same plant. Their structures were elucidated using spectroscopic methods (MS, NMR and IR) and by comparison with some data found in literature. Free radical scavenging (DPPH) and antibacterial potentials of extracts and compounds were also evaluated in this work. For radical scavenging, results showed that it is phaseollidin (7) which is responsible of radical scavenging potential in the ethyl acetate extract of roots barks with value of 1.31 mg/ml; for antibacterial, one of the tested compounds abyssinone-IV-4'-methylether (5) exhibited antibacterial activities against two strains: Providencia stuartiiATCC 29916 and Enterobacter aerogenes ATCC 13048 with MIC values of 25μg/ml.

In 2012, the Walloon Government ordered the Walloon Institute for Prospective, Evaluation and Statistics (IWEPS) to calculate five indexes in order to guide and evaluate the public actions, together with the GDP. The index for the conditions of human well-being (CWBI) is presently the first step in the elaboration of the wellbeing index. The methodology is the one used by the Council of Europe. Actually, the CWBI is calculated by using 60 basic indicators, gathered into 8 families. After normalisation, the CWBI is the arithmetic mean of the 60 basic indicators, each of them having the same weight. The CWBI was calculated for the 262 communes of Wallonia and varies from 0.428 to 0.674, with a regional mean of 0.572. An opposition between urban and rural communes clearly appears, the last ones having the best scores. Communes along the borders of Germany and Luxemburg have the highest indexes, while communes in the old industrial areas have the lowest scores. Employment, income, family relations and security are the factors which are the most narrowly linked to the CWBI. At the communal level, social and security expenses per capita have a significant and negative correlation coefficient with the CWBI. In the future, in order to elaborate a finer index, new data, up to now not directly available, will be collected at the communal level, about quantitative and qualitative aspects. [less ▲]

The biotic poverty of tropical Africa has been interpreted in terms of massive extinctions caused by historical climate shifts. While recolonisation has been hampered in tropical angiosperms that are characterized by low dispersal capacities, tropical bryophytes exhibit high dispersal syndromes. Using tropical mosses as a model, we test here the hypotheses that (i) species-turnover is higher within than among continents and (ii) in tropical Africa, extant distribution patterns are better explained by variation in environmental conditions (species turnover) than by the ordered loss of species along gradients of recolonisation from putative refugia (species nestedness). Global beta diversity was slightly, but significantly higher among than within tropical regions, suggesting that geographic isolation rather than regional environmental variation shapes macroecological patterns of moss species distributions. Species turnover was, however, systematically higher than nestedness within each tropical region, and nestedness in tropical Africa was not significantly higher than in other tropical regions. The results therefore do not support the hypothesis of an ordered loss of species due to delays in the recolonisation of formerly savanna areas from refugia. Rather, the low species richness in Africa is interpreted in terms of shifts towards specialized, but species-poor communities along sharp ecological gradients. [less ▲]

L’objectif de cette recherche est d’examiner le développement des habiletés métacognitives au cours de l’enfance, en prêtant une attention particulière aux variables et processus impliqués dans l’acquisition des connaissances concernant le fonctionnement général de la cognition. Précisément, le but de cette étude est de démontrer l’impact des atteintes exécutives résultant d’un traumatisme crânien sur le développement des connaissances explicites des enfants en métamémoire. Dans ce but, 22 enfants (âgés de 7 à 14 ans) ayant subi un traumatisme crânien modéré à sévère ont été recrutés et divisés en deux groupes en fonction de la gravité de leurs atteintes exécutives (déterminée par le score obtenu à une épreuve d’inhibition, de flexibilité et de mémoire de travail). Au total, dix enfants constituaient le groupe ne montrant pas d’altération du fonctionnement tandis que douze enfants constituaient le groupe montrant des altérations significatives du fonctionnement exécutif. Les deux groupes de patients étaient équivalents à tous les autres niveaux du fonctionnement cognitif. Chaque patient a également été apparié à deux enfants contrôles (n = 44) en fonction de l’âge et du niveau socio-économique. Conformément à l’hypothèse généralement avancée dans la littérature concernant le rôle des fonctions exécutives dans l’apprentissage des connaissances métacognitives au cours de l’enfance, les résultats montrent une différence significative entre les deux groupes de patients au niveau des scores à l’échelle de métamémoire. De même, de moins bonnes performance à l’échelle de métamémoire sont observées pour le groupe de patients démontrant une atteinte exécutive comparativement au groupe d’enfants contrôles. Aucune différence n’était observée entre le groupe de patients ne démontrant pas d’atteinte exécutive et le groupe contrôle. Ces différents résultats suggèrent l’implication des fonctions exécutives dans l’acquisition des connaissances en métamémoire au cours de l’enfance. L’implication de ces résultats pour la prise en charge des patients souffrant de déficits exécutifs sera discutée. [less ▲]

Parmi les grands représentants de la « génération 1905 », selon l’expression de J.-F. Sirinelli, Sartre passe pour celui qui a refusé l’enseignement d’Alain alors que des penseurs aussi différents qu’Aron, Canguilhem ou Hyppolite acceptaient, au moins pour un temps, l’enseignement du maître. Cette appréciation expéditive ne fait droit ni à ce qu’on sait aujourd’hui des premières tentatives philosophiques de Sartre ni au travail inlassable de relecture d’Alain que Sartre aura mené, en sous-main, tout au long de sa trajectoire intellectuelle. Dans cet article, on procédera dès lors, d’une part, au repérage de l’influence d’Alain dans une série de textes, souvent posthumes, qui passent pour des textes préparatoires aux grandes œuvres. On montrera, d’autre part, que cette influence d’Alain s’insinue jusqu’au cœur de l’ontologie phénoménologique de Sartre, dans L’être et le néant, puis dans les prolongements que Sartre y a donnés dans ses psychanalyses existentielles. Au total, on montrera que la plupart des interprétations récentes de Sartre (Coorebyter, Breeur, Gély, Giovannangeli, J. Simont, etc.), depuis une dizaine d’années, se resserrent autour de la relation largement insoupçonnée que l’ontologie phénoménologique sartrienne entretient avec la pensée d’Alain. [less ▲]

In HOSIOS – A Semantic Study of Greek Piety Saskia Peels elucidates the semantics of the Ancient Greek adjective hosios and its cognates. Traditionally rendered as ‘piety’, hosios was a key notion in Classical Greek religion and reflected a core value in Athenian democracy. Since antiquity, its meaning and usage have puzzled many. This study sets out to resolve various scholarly debates on the semantics of hosios by focusing on the idea of lexical competition. It illuminates the semantic relationship between hosios and its near-synonyms eusebês and dikaios, and the connection to the notion of the ‘sacred’. Using insights from modern linguistic theory, the book also aims to improve methods for research into the lexical semantics of a dead language. [less ▲]

This experiment examined how knowledge of memory strategies and of memory functioning improves during childhood and what variables are involved in this development. Three main aspects of metamemory were assessed based on the performance of a group of 100 children (aged 4, 6, 9 and 11 years) on a battery of executive tasks. At the same time, the influence of variables such as intelligence, vocabulary and parental education level was also investigated. Results of mediation analyses reveal that the relation between children’s age and internal strategy knowledge was partially mediated by working memory skills but that executive functions did not mediate the impact of chronological age on children’s knowledge of external strategies or of memory functioning. Additionally, verbal fluency predicted internal and external strategy knowledge. Implications for general learning theories in childhood are discussed [less ▲]

To improve cotton fiber fineness, the (Gossypium hirsutum L. × Gossypium longicalyx Hutch. & Lee)² allohexaploid and the [(Gossypium hirsutum L. × Gossypium thurberi To d . ) ² × G. longicalyx] allotetraploid were backcrossed to G. hirsutum to produce introgressed genetic stocks. The ribbon width (RW) of 600 swelled fibers produced by the hybrids, their parents, and their backcross progeny were analyzed for each compared genotype using an optical microscope. The RWs varied between 6.41±2.15 µm for G. longicalyx to 17.45±2.98 µm for the G. hirsutum parent cultivar C2. Fibers produced by the trispecific hybrids and their progeny were finer than the bispecific hybrid material. For the introgressed stocks, the lowest RWs were observed for the trispecific hybrid (10.79±2.14 µm) and certain backcross progenies (between 11.98±1.27 µm to 12.71±1.61 µm). The allohexaploid RW was 13.58±1.41 µm. One of its tetraploid progeny produced approximately the same value (13.94±2.48 µm). These results show that G. longicalyx is a potential genetic stock for cotton fiber fineness improvement. The genetic stocks produced are valuable materials for improve the fineness of cotton fiber.

Background: Ovarian tissue preservation is proposed to patients at risk of premature ovarian failure, but this procedure still needs to be optimized. To limit injury during ovarian tissue cryopreservation, anti-apoptotic drugs were added to the transport and freezing media of ovarian cortex tissue. Methods: Sheep ovaries were transported, prepared and frozen in solutions containing vehicle or anti-apoptotic drugs (Z-VAD-FMK, a pan-caspase inhibitor, or sphingosine-1-phosphate (S1P), a bioactive lipid). After the tissue was thawed, the ovarian cortex was cultured for 2 or 6 days. Follicular quantification and morphological and proliferation analyses were performed on histological sections. Results: After 2 days of culture, S1P improved the quality of primordial follicles; higher densities of morphologically normal and proliferative primordial follicles were found. Z-VAD-FMK displayed similar effects by preserving global primordial follicular density, but this effect was evident after 6 days of culture. This drug also improved cell proliferation after 2 and 6 days of culture. Conclusions: Our results showed that the addition of S1P or Z-VAD-FMK to the transport and freezing media prior to ovarian tissue cryopreservation improves primordial follicular quality and therefore improves global tissue survival. This should ultimately lead to improved fertility restoration after auto-transplantation. [less ▲]

One of the very few polemical texts of the poet, the latter paper deals with mechanisms of poetical meaning and reciprocal adjustment of both the literary text and his reader. Three kinds of censorship are at stake here. Censorship by the obscurity (Proust). Censorship of the obscurity (Muhlfeld). Censorship with and for the sake of obscurity (Mallarmé).

In a study of elderly AML patients treated with the hypomethylating agent decitabine (DAC), we noted a surprisingly favorable outcome in the (usually very unfavorable) subgroup with two or more autosomal monosomies (MK2+) within a complex karyotype (Lübbert et al., Haematologica 97:393-401, 2012). We now analyzed 206 myelodysplastic syndrome (MDS) patients (88 % of 233 patients randomized in the EORTC/GMDSSG phase III trial 06011, 61 of them with RAEBt, i.e. AML by WHO) with cytogenetics informative for MK status.. Endpoints are the following: complete/partial (CR/PR) and overall response rate (ORR) and progression-free (PFS) and overall survival (OS). Cytogenetic subgroups are the following: 63 cytogenetically normal (CN) patients, 143 with cytogenetic abnormalities, 73 of them MKnegative (MK−), and 70 MK-positive (MK+). These MK+ patients could be divided into 17 with a single autosomal monosomy (MK1) and 53 with at least two monosomies (MK2+). ORR with DAC in CN patients: 36.1 %, in MK−patients: 16.7 %, in MK+ patients: 43.6 % (MK1: 44.4 %, MK2+ 43.3 %). PFS was prolonged by DAC compared to best supportive care (BSC) in the CN (hazard ratio (HR) 0.55, 99 % confidence interval (CI), 0.26; 1.15, p=0.03) and MK2+ (HR 0.50; 99%CI, 0.23; 1.06, p=0.016) but not in the MK−, MK+, and MK1 subgroups. OS was not improved by DAC in any subgroup. In conclusion, we demonstrate for the first time in a randomized phase III trial that high-risk MDS patients with complex karyotypes harboring two or more autosomal monosomies attain encouraging responses and have improved PFS with DAC treatment compared to BSC.
