Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

The L2 Acquisition of French Interrogatives: Pragmatic Inferences in Clefted wh-Questions

Languages, 2021
The present study aims to elaborate on the understanding of the second language (L2) acquisition of French interrogatives by focusing on clefted (subject) wh-questions, structures that are largely absent in prior L2 literature.

Nouns for visual objects: A hypothesis of the vision-language interface

Language Sciences, 2019
Abstract We propose an interpretation of the vision process and a structural analysis of nouns and nominal reference which make it possible to relate the visual/cognitive and the linguistic encapsulation of objecthood in a rigorous way. The result of this integrated hypothesis is a predictive account of possible and impossible nouns lexicalizing ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

The subject realization in L2 Spanish by German L1 speakers

Isogloss
This article deals with the realization of referential subjects in the L2 Spanish of German (adult) native speakers. The acquisition of a null subject grammar by speakers of a non-null subject language has drawn considerable attention in generative ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Mussel adhesive protein coating: A potential therapeutic method for self-healing of cracked teeth

Dental Hypotheses, 2015
Introduction: Nowadays, cracked tooth syndrome is the third main cause of tooth extraction, following caries and periodontal diseases, done in almost all the dental clinics. Nevertheless, the diagnosis and treatment of this condition remain controversial.

Parametrical Study of Freshwater–Saltwater Interface Dynamic

Modelling and Simulation in Engineering, 2023
In this paper, a saltwater intrusion model, in view to study the dynamics of the interface between the saltwater and the freshwater in a coastal aquifer, is established. This dynamic is caused by an injection of saltwater and a freshwater pumping through

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
