Metabolic constituents of grapevine and grape-derived products
The numerous uses of the grapevine fruit, especially for wine and beverages, have made it one of the most important plants worldwide. The phytochemistry of grapevine is rich in a wide range of compounds. Many of them are renowned for their numerous medicinal uses. The production of grapevine metabolites is highly conditioned by many factors like environment or pathogen attack. Some grapevine phytoalexins have gained a great deal of attention due to their antimicrobial activities, being also involved in the induction of resistance in grapevine against those pathogens. Meanwhile grapevine biotechnology is still evolving, thanks to the technological advance of modern science, and biotechnologists are making huge efforts to produce grapevine cultivars of desired characteristics. In this paper, important metabolites from grapevine and grape derived products like wine will be reviewed with their health promoting effects and their role against certain stress factors in grapevine physiology

Fosses étroites aux parois sub-verticales dans le Nord de la France : élaboration d’une démarche interdisciplinaire et premiers résultats
Seit einigen Jahren beschäftigen sich die Archäologen mit der Frage nach der Funktion einiger recht tiefer Gruben mit stark verjüngter Basis und, in ihrem unteren Bereich, subvertikalen Wänden. Diese Gruben werden mehrheitlich in die Zeit zwischen dem Neolithikum und der Bronzezeit datiert. Die fachübergreifende Vorgehensweise und der Einsatz der paläoumweltlichen Disziplinen erscheinen uns ausschlaggebend zu sein, um die konkreten Argumente zu liefern, die es zukünftig ermöglichen werden, die unterschiedlichen aktuellen funktionellen Hypothesen zu differenzieren und wesentliche Elemente einer Demonstration vorzulegen. Das Ziel dieses Beitrages besteht vor allem in der Eröffnung der Diskussion. Zu diesem Zweck schlagen wir neue Rubriken für eine zukünftige archäologische die Paläoökologie betreffende Datenbasis vor. Dieser Beitrag ist komplementär mit demjenigen von Achard et al. zum selben ThemaSince a few years, archaeologists ask about the function of certain types of pits that typically present a clear narrowing of their base and are rather long and deep, with a sub-vertical base of walls. They usually have a dating that is Neolithic or Bronze Age. Interdisciplinarity and the application of palaeoenvironnemental disciplines appear to be very useful in order to deliver factual arguments that will permit in the future to discriminate between the different proposals for their fonctioning and produce the elements of its demonstration. The goal of this contribution is most of all to open the debate towards such new informations, among others by proposing additional columns for the planned archaeological and environmental data basis of these pits. This contribution is understood as a complement to the one of Achard et al. on the same subject.Depuis quelques années, des archéologues s’interrogent sur la fonction de certaines fosses assez profondes, à base nettement rétrécie, aux parois inférieures sub-verticales et dont la plupart ont une fourchette globale allant du Néolithique à l’âge du Bronze. L’interdisciplinarité et l’application des disciplines paléoenvironnementales nous semblent déterminantes pour fournir des arguments concrets permettant à l’avenir de discriminer les différentes propositions fonctionnelles actuelles et d’apporter des éléments constitutifs d’une démonstration. L’objectif de cette contribution est surtout d’ouvrir le débat et ce en commençant par proposer de nouvelles rubriques au sein d’une future base de données archéologique et environnementale. .
