Isolation, Identification, and Chemical Synthesis of 6α-Hydroxyraumacline: A Novel Alkaloid from CultivatedRauwolfia serpentinaCells
1992
From RAUWOLFIA SERPENTINA cells cultivated in the presence of ajmaline ( 2) the new indole alkaloid, 6alpha-hydroxyraumacline ( 1), was isolated. This alkaloid also occurs in significant amounts in the nutrition medium. A simple chemical synthesis of 1 was developed starting from ajmaline ( 2).
Relaxation by urocortin of human saphenous veins
2002
Urocortin, an endogenous peptide structurally related to corticotropin-releasing factor (CRF), has potent cardiovascular effects, suggesting that it may be of significance in cardiovascular regulation. The objective of this study was to analyse the effects of urocortin and its action mechanisms on human blood vessels. To this, 3 mm long segments from human saphenous veins were prepared for isometric tension recording in an organ bath. In the segments at basal resting tone, urocortin did not produce any effect, but in the segments precontracted with endothelin-1 (1 – 10 nM), urocortin (1 pM – 10 nM) produced concentration-dependent relaxation. This relaxation was not modified by the inhibito…
Subjugation, freedom, and recognition in Poulain de la Barre and Simone de Beauvoir
2022
In 1949, Simone de Beauvoir cited the fairly unknown author Poulain de la Barre in an epigraph for The Second Sex (1949). When reading The Second Sex, one soon realizes that there are profound similarities between the two authors’ discussions of women’s situation. Both Poulain and Beauvoir view the subjection of women as a process that includes choice as well as force. Liberation necessarily requires overcoming opinions rooted in custom and prejudice. The article develops a comparison between the arguments of Poulain and Beauvoir in order to illuminate interesting features in the works of both authors. The focus is on similarities as well as differences. The first section examines how preju…
Vingt ans de réformes des systèmes éducatifs dans les pays en développement
2005
La situation politique, économique et sociale des pays en développement est difficile alors que pratiquement tous, depuis maintenant plus de vingt ans, ont mis en œuvre des réformes très importantes élaborées en fonction des plans d'ajustement structurel initiés par le FMI, et financées par des projets soutenus par les grands bailleurs de fonds internationaux (multilatéraux ou bilatéraux). Panvi ces pays, cinquante et un ont été identifiés par la Banque mondiale comme présentant un niveau de développement tellement faible, associé à un taux d'endettement tellement élevé, qu'ils sont susceptibles de bénéficier de l'initiative dite PPTE (Pays Pauvres Très Endettés). L'objectif prioritaire de …
Evaluation of beauvericin and enniatins in Italian cereal products and multicereal food by liquid chromatography coupled to triple quadrupole mass sp…
2013
In this study, 48 multicereal baby foods samples including 25 of pasta and 23 of multicereal baby foods from supermarkets of Campania region (Italy) were analysed for evaluating the presence of beauvericin (BEA) and enniatins (ENs) A, A1, B, B1 and B4. Subsequently to evaluate the risk exposure of Italian population and infant population over the consumption of pasta or multicereal baby food, was, respectively, evaluated. For the above mentioned evaluation, a method developed in our laboratory by liquid chromatography tandem mass spectrometry was used. A liquid phase dispersion procedure was optimised for the simultaneous extraction of BEA and the five ENs from multicereal baby food samples…
Implantations, activités et relations des établissements d'assistance en Bourgogne à la fin du Moyen Age
2012
The study presented here is the conclusion of an inventory about hospitals having existed on the territory of some dioceses (Autun, Auxerre, Chalon-sur-Saône, Nevers and the south of that of Langres diocese) between XIIth and XVth centuries. Based on the data collected, an atlas of assistance and a directory of sources on medieval hospitals of the study area has been made. The compiled informations proved to be very different but also very heterogeneous. Nevertheless, reflexions were conducted about the characteristics of these hospitals and their relationships with their economic, religious, political and social environments. It revolves around three parts dealing by turns the influence of…

Coffee Silverskin and Spent Coffee Suitable as Neuroprotectors against Cell Death by Beauvericin and α-Zearalenol: Evaluating Strategies of Treatment
2021
Coffee silverskin and spent coffee have been evaluated in a neuroblastoma cell line (SH-SY5Y cells) against beauvericin (BEA) and α-zearalenol (α-ZEL)-induced cytotoxicity with different strategies of treatment. First, the direct treatment of mycotoxins and coffee by-products extracts in SH-SY5Y cells was assayed. IC50 values for α-ZEL were 20.8 and 14.0 µM for 48 h and 72 h, respectively and, for BEA only at 72 h, it was 2.5 µM. Afterwards, the pre-treatment with spent coffee obtained by boiling water increased cell viability for α-ZEL at 24 h and 48 h from 10% to 16% and from 25% to 30%, respectively
