In Vivo and In Vitro Binding of Vip3Aa to Spodoptera frugiperda Midgut and Characterization of Binding Sites by 125 I Radiolabeling
2014
ABSTRACT Bacillus thuringiensis vegetative insecticidal proteins (Vip3A) have been recently introduced in important crops as a strategy to delay the emerging resistance to the existing Cry toxins. The mode of action of Vip3A proteins has been studied in Spodoptera frugiperda with the aim of characterizing their binding to the insect midgut. Immunofluorescence histological localization of Vip3Aa in the midgut of intoxicated larvae showed that Vip3Aa bound to the brush border membrane along the entire apical surface. The presence of fluorescence in the cytoplasm of epithelial cells seems to suggest internalization of Vip3Aa or a fragment of it. Successful radiolabeling and optimization of the…
Bacillus thuringiensis Cry1Ac Toxin-Binding and Pore-Forming Activity in Brush Border Membrane Vesicles Prepared from Anterior and Posterior Midgut R…
2008
ABSTRACT It is generally accepted that Bacillus thuringiensis Cry toxins insert into the apical membrane of the larval midgut after binding to specific receptors, and there is evidence that the distribution of binding molecules along the midgut is not uniform. By use of the voltage-sensitive dye DiSC 3 (5) and 125 I-labeled Cry1Ac, we have measured the effect of Cry1Ac in terms of permeabilization capacity and of binding parameters on brush border membrane vesicles (BBMV) prepared from the anterior and the posterior regions of the larval midgut from two insect species, Manduca sexta and Helicoverpa armigera . The permeabilizing activity was significantly higher with BBMV from the posterior …
Constraint Cellular Automata for Urban Development Simulation: An Application to the Strasbourg-Kehl Cross-Border Area
2017
AcknowledgementsThe research presented in this chapter is part of the Smart. Boundary project supported by the Fonds National de la Recherche in Luxembourg and CNRS in France (ref. INTER/CNRS/12/02). The authors would like also to thank the Grasp Program of LISER for allowing cross-collaboration between the two teams based in Luxembourg and France.; International audience; Urban sprawl and space consumption have become key issues in sustainable territorial development. Traditional planning approaches are often insufficient to anticipate their complex spatial consequences, especially in cross-border areas. Such complexity requires the use of dynamic spatial simulations and the development of…
The Double-Door Tongue Flap for Total Cheek Muscosa Defects
1988
Lining of total cheek mucosa defects can be accomplished by opening the tongue along its lateral border and preparing two myomucosa flaps that can be swung upward and downward like a double door to be sutured into the defect. The tongue is released 3 weeks later in a second-stage operation. The operation is quick and easy compared with other methods to achieve lining for such defects. Tongue function is not impaired after healing of the second-stage operation.
The catechol o-methyltransferase (COMT) val158met polymorphism modulates the association of serious life events (SLE) and impulsive aggression in fem…

Wagner S, Baskaya O, Anicker NJ, Dahmen N, Lieb K, Tadic A. The catechol o‐methyltransferase (COMT) val158met polymorphism modulates the association of serious life events (SLE) and impulsive aggression in female patients with borderline personality disorder (BPD). Objective: We analyzed i) the effects of serious life events (SLE) on impulsive aggression, and ii) modulating effects of the COMT Val158Met polymorphism on the association between SLEs and impulsive aggression in borderline personality disorder (BPD). Method: One hundred and twelve female BPD patients from Germany were included in this study. Impulsive aggression was assessed by the Buss‐Durkee‐Hostility Inventory (BDHI). Result…
A new paradigm for pattern classification: Nearest Border Techniques
2013
Published version of a chapter in the book: AI 2013: Advances in Artificial Intelligence. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-319-03680-9_44 There are many paradigms for pattern classification. As opposed to these, this paper introduces a paradigm that has not been reported in the literature earlier, which we shall refer to as the Nearest Border (NB) paradigm. The philosophy for developing such a NB strategy is as follows: Given the training data set for each class, we shall first attempt to create borders for each individual class. After that, we advocate that testing is accomplished by assigning the test sample to the class whose border it lies closest to…
Comparison of Statistical Methods for the Detection of Contrast Material in Echocardiographic Image Sequences
1987
Ultrasonic imaging of the heart is a diagnostic tool which is increasingly used in cardiology. In addition to the representation of important anatomical information two dimensional images provided by mechanical or electronically steered sector scanners can be used for the extraction of functional parameters of the heart (as e.g. enddiastolic volume or ejection fraction). A poor definition of the endocardial border especially resulting from the noisy appearance of the images and from qualitatively restricted echocardiograms leads to uncertainties in the quantitative analysis and therefore requires refined methods for the determination of functional parameters. Our investigations which are ba…
Confin(at)i Mediterranei e Afroamericani. Una performance geografica sulla disumanizzazione
2020
Studiare la questione mediterranea soltanto dentro le aule universitarie non ci permette di restituire una realtà sfaccettata che viene proposta all’opinione pubblica con un’unica parola d’ordine: invasione. La performance E l’Europa disumanizzò se stessa mi ha permesso di presentare la storia di schiavi e fuggitivi per un’audience più vasta. Incentrata sul libro di Toni Morrison, Beloved, rimbalza tra gli effetti delle storie dell’Atlantico Nero e quelli dell’odierno Mediterraneo. Il saggio si propone di tracciare alcune direzioni che possano aiutare a indagare le diverse linee di confine che segnano la rugosità della modernità del nostro globo. Per fare questo, si prova a rispondere a tre…

The nationality of companies in French law
2012
The development of international economic relations and the construction of an integrated European area, both from an economic and a political point of view, has revived the debate on the nationality of trading companies. The question is not so much whether trading companies have a nationality on an equal footing with natural persons – solutions have long been accepted by international doctrine and jurisprudence – but rather to determine how this notion has evolved and adapted to the constraints on the one hand, of a globalized market economy and, on the other hand, of European Union law which overturns the traditionally accepted solutions of nationality of trading companies into the legal …
