Persistent Bilateral [18F]THK5351 and Migrating Unilateral [18F]FDG Uptake in Anti‐LGI1 Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Anti–leucine‐rich glioma‐inactivated 1 encephalitis (LGI1‐E) can cause persistent cognitive deficits, but the mechanisms remain unclear. A 40‐year‐old woman with LGI1‐E presented with subacute cognitive deficits and showed mild left medial temporal lobe (MTL) swelling and fluid‐attenuated inversion recovery (FLAIR) hyperintensity on initial ...

Stacking 21 cm Maps around Lyα Emitters during Reionization: Prospects for a Cross-correlation Detection with the Hydrogen Epoch of Reionization Array

The Astrophysical Journal
Observations of the redshifted 21 cm line during the Epoch of Reionization will open a new window to probe the intergalactic medium during the formation of the first stars, galaxies, and black holes. A particularly promising route to an initial detection

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

Advanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Extracting the Epoch of Reionization Signal with 3D U-Net Neural Networks Using a Data-driven Systematic Effect Model

The Astrophysical Journal
Neutral hydrogen serves as a crucial probe for the Cosmic Dawn and the Epoch of Reionization (EoR). Actual observations of the 21 cm signal often encounter challenges such as thermal noise and various systematic effects.
