Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Asymptotically I-Cesaro equivalence of sequences of sets

open access: yesUniversal Journal of Mathematics and Applications, 2018
In this paper, we defined concepts of asymptotically $\mathcal{I}$-Cesaro equivalence and investigate the relationships between the concepts of asymptotically strongly $\mathcal{I}$-Cesaro equivalence, asymptotically strongly $\mathcal{I}$-lacunary ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Le changement de catégorie en Traduction

open access: yesTraduction et Langues, 2008
La Théorie de la Traduction et la Linguistique Contrastive (LC) sont deux domaines de la linguistique appliquée. La traduction pourrait ainsi être considérée comme une application de la linguistique contrastive.

Dossier : La fabrique de la compensation écologique : controverses et pratiques – Introduction. La fabrique de la compensation écologique, un approfondissement de la modernisation écologique ?★

open access: yesNatures Sciences Sociétés, 2018
Longtemps peu appliquée, l’obligation de compensation écologique s’est peu à peu imposée, en droit français, aux projets soumis à évaluation environnementale.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Les problèmes d’ordre lexical dans Mon cher fils de Leïla Sebbar المشكلات المعجمية في رواية ابني العزيز للكاتبة ليلي سيبار

open access: yesمجلة کلية الآداب. جامعة أسوان
La traduction est bien plus qu’un simple passage d’une langue à une autre. Elle est un acte de médiation culturelle, une passerelle entre les peuples, les sociétés et les imaginaires. Traduire un texte littéraire, c’est transmettre une voix, une émotion,

Facilitation of equivalence – equivalence responding: generalization of relational responses

open access: yesInternational Journal of Psychological Research, 2011
Equivalence-equivalence responding (Eq-Eq) has become a behaviour analytic model of analogical reasoning. In previous works it was demonstrated that the exposition to a non-arbitrary relational task (facilitation procedure) improves performance in Eq-Eq ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
