Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

The Correlation between Language Proficiency and the Use of Lexical Collocations by Algerian EFL Undergraduate Students in Essay Writings: a Case Study of Verb+ Noun Collocations

open access: yesRevue des Sciences Humaines, 2017
     ‘Pseudo-native speaker’ is the term given to a foreign language learner who has reached a high level of proficiency. Such level of proficiency is characterised by the mastery of grammar, vocabulary, and pronunciation.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Evaluating the influence of chemical composition and morphology of waxes on the fusion behaviour of rigid PVC

open access: yeseXPRESS Polymer Letters
A set of linear Fischer-Tropsch (FT) waxes were oxidized to various degrees by utilizing an ozonolysis method. These waxes were comprehensively characterized in terms of their chemical composition, thermal behaviour, molecular weight distributions, and ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

The Impact of Translation on Reading Comprehension for EST Learners - A Case Study of Computer Science Students at Constantine 2 University

open access: yesRevue des Sciences Humaines, 2019
We study the impact of introducing EST concepts for computer science learners through the use of translation. We have opted for the use of an on-the-fly translation, in which the teacher uses translation just to explain ambiguous terms or ideas related ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
