Tl2[Te2O6]: The First Mixed‐Valent Oxidotellurate(IV/VI) of Thallium(I)

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 18, December 10, 2025.
The layered crystal structure of the mixed‐valent thallium(I) oxidotellurate(IV/VI), Tl2[Te2O6]. Single crystals of Tl2[Te2O6] were grown hydrothermally at 220 °C starting from telluric acid and elemental thallium, whereas single‐phase microcrystalline material was obtained from solid‐state reactions between Tl2CO3, Tl2O3, and TeO2 in evacuated silica ...

The Knockdown of ACTL6A Enhances the Radiosensitivity of Esophageal Squamous Cell Carcinoma by Modulating the Wnt/β‐Catenin Signaling Pathway

open access: yesThe FASEB Journal, Volume 39, Issue 20, 31 October 2025.
ACTL6A, A new radiosensitizing target for esophageal squamous cell carcinoma? ABSTRACT Actin‐like protein 6A (ACTL6A) is thought to be associated with the survival and prognosis of patients with a variety of human cancers. This study investigates the effect of ACTL6A knockdown on ESCC radiosensitivity and explores molecular mechanisms that may enhance ...

Reference Values for Water‐Specific T1, Intermuscular and Intramuscular Fat Content in Skeletal Muscle at 2.89 T

open access: yesJournal of Magnetic Resonance Imaging, Volume 62, Issue 1, Page 146-159, July 2025.
Background MRI offers quantification of proton density fat fraction (PDFF) and tissue characteristics with T1 mapping. The influence of age, sex, and the potential confounding effects of fat on T1 values in skeletal muscle in healthy adults are insufficiently known.

Whole liver phase‐based R2 mapping in liver iron overload within a breath‐hold

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 1, Page 183-198, July 2025.
Abstract Purpose Diagnosis and treatment monitoring of iron overload increasingly relies on non‐invasive MRI‐based measurement of liver iron concentration (LIC). Liver R2 mapping is known to correlate well with LIC. However, traditional spin‐echo based R2 mapping methods have drawbacks such as long acquisition times and limited volumetric coverage.
