Fronting in Old Spanish

open access: yesGlossa, 2020
The article focuses on a cross-genre study of fronting phenomena in 13th Century Old Spanish. In particular, we study stage topics and deictic fronting, fronting in quotative inversion, quantifier fronting and information/broad/weak focus fronting ...

Information Structure in Sign Languages

open access: yes, 2016
This chapter demonstrates that the Information Structure notions Topic and Focus are relevant for sign languages, just as they are for spoken languages. Data from various sign languages reveal that, across sign languages, Information Structure is encoded

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Photosynthesis of Au8Cu6 nanocluster for photocatalysis in oxidative functionalization of alkynes

open access: yesNature Communications
Ligand-protected metal nanoclusters provide an ideal platform for investigating photoredox catalysis. The central challenge is balancing their stability and catalytic activity.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Emerging Opportunities of Metal Nanoclusters for Photocatalytic Organic Synthesis

open access: yesAggregate
Atomically precise metal nanoclusters have emerged as versatile photocatalysts for photo‐induced organic reactions owing to their unique photophysical properties, such as broad absorption cross‐section, long excited‐state lifetime, and tunable excited ...

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Information Structure

open access: yes, 2007
Abstract This introduction to the role of information structure in grammar discusses a wide range of phenomena on the syntax-information structure interface. It examines theories of information structure and considers their effectiveness in explaining whether and how information structure maps onto syntax in discourse.

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...
