Identification of an Osteochondral Erosion Process in Gout Driven by Fibrinogen‐Integrin Activation and Local MSU Crystallization

Advanced Science, EarlyView.
Cartilage injury promotes local fibrinogen deposition, which accelerates monosodium urate crystallization and activates integrin‐mediated matrix‐degradation. This self‐amplifying cycle drives gout‐related cartilage erosion. Disrupting fibrinogen deposition or restoring the cartilage barrier could interrupt this vicious cycle.

Strontium-isotope stratigraphy and oxygen- and carbon-isotope record of Middle Jurassic to Early Cretaceous belemnites in the South Atlantic

, 2002
87Sr/86Sr data of belemnites are presented from a Middle Jurassic-Early Cretaceous succession from the Falkland Plateau (Deep Sea Drilling Project Sites 511 and 330) that was deposited in a periodically anoxic, semi-enclosed shallow water basin ...

Stabilising the Lattice Oxygen Oxidation Mechanism Through Iridium Single Atoms in Chromium‐Doped Cobalt Iron Layered Double Hydroxides

Advanced Science, EarlyView.
Iridium single atoms and Cr doping synergistically activate and stabilise the lattice oxygen oxidation mechanism in CoFe layered double hydroxides. Electronic modulation enhances metal–oxygen covalency, suppresses over‐oxidation, and enables durable oxygen evolution, delivering high‐performance anion exchange membrane water electrolysis with ...

Preliminary strontium isotope (87Sr/86Sr) baselines for the Bjäre Peninsula and Halland in southern Sweden

Frontiers in Environmental Archaeology
During the last decade, the application of strontium isotope analysis (87Sr/86Sr) has increased rapidly. The understanding of the strontium isoscape and the construction of a strontium isotope baseline in southern Scandinavia are biased toward Denmark ...

Strontium- and lead-isotope composition of some basalts at DSDP Hole 69-504B

, 1983
Seventeen whole-rock samples, generally taken at 25- to 50-meter intervals from 5 to 560 meters sub-basement in Deep Sea Drilling Project Hole 504B, were analyzed for 87Sr/86Sr ratios, and rubidium and strontium concentrations.

Disentangling Elemental Roles in an Amorphous Medium‐Entropy Electrocatalyst for Oxygen Evolution

Advanced Science, EarlyView.
An amorphous medium‐entropy FeCoNiMo‐a catalyst with a unique nanoring architecture is synthesized via a solvothermal method. The catalyst exhibits exceptional stability in anion exchange membrane water electrolysis, maintaining stable operation for over 600 h at 1 A cm−2.

A Quality Control Assay to Access the HCl Molarity of Radionuclide Solutions

Chemosensors, 2016
Strontium-82 is produced by proton activation of a rubidium chloride target in an accelerator or cyclotron and purified by ion exchange chromatography. The Strontrium-82 is used in Cardigen generators to produce Rubidium-82 for cardiac imaging.
