Gut–Brain Axis Modulation by Short‐Chain Fatty Acids Exerts Disease‐Modifying Effects in a Murine Model of Drug‐Resistant Epilepsy

Annals of Neurology, EarlyView.
Objective Drug‐resistant epilepsy (DRE) remains a clinical challenge, as therapies modifying disease trajectory are lacking. Increasing evidence implicates gut microbiota dysbiosis in epilepsy pathophysiology, with short‐chain fatty acids (SCFAs) emerging as key microbial metabolites with neuroprotective and anti‐inflammatory properties.

Formation of Gallium Monofluoride in the Coordination Sphere of Nickel

Angewandte Chemie, EarlyView.
The elusive gas‐phase species gallium monofluoride forms selectively in the coordination sphere of a nickel(II) centre as a product of C(sp3)–F bond activation, with a weakly coordinating anion as the fluorine source. The herein reported gallium monofluoride ligand acts as a very strong σ‐donor ligand at nickel and serves as a fluorine donor towards ...

CO2‐Induced Reverse Lattice Oxygen Spillover on Pt/CeO2 Enables Sulfur‐Resistant Dry Reforming of Methane

Angewandte Chemie, EarlyView.
A critical step, dry reforming of methane (DRM) converts biogas into useful syngas. Yet trace H2S in biogas rapidly poisons DRM catalysts, limiting practical use. We developed a robust Pt/CeO2 catalyst sustaining DRM activity via CO2‐induced reverse lattice oxygen spillover in H2S‐rich environments.

New Water Oxidation Mechanism in Photosystem II Resolves Major Experimental Controversies

Angewandte Chemie, EarlyView.
In Photosystem II Oxygen Evolving Complex, we discovered the O3‐O6 peroxide at lower energy. Assignment of the O3 ligated by histidine (His337) as a slow exchanging substrate and its coupling with O6 give the O─O bond formation mechanism most consistent with all currently available experimental data. Proposal shows how protein environment can steer the

Water‐Mediated Phosphoryl Wires Stabilize Pathological Tau Fibrils

Angewandte Chemie, EarlyView.
Extended 1D phosphoryl “wires” stabilize in‐register amyloid tau fibrils, as demonstrated by multiple‐quantum spin‐counting NMR, TEM, and MD simulations, using fibrils of tau peptide jR2R3‐P301L (tau295–313) with phosphorylation at S305 or Y310. ABSTRACT Hyperphosphorylation of tau is a hallmark of tauopathies, with specific phosphorylation sites ...
