Voltage‐gated potassium channels mediate thyroid hormone control of skeletal muscle excitability

The Journal of Physiology, EarlyView.
Abstract figure legend Thyroid hormone (TH)‐dependent remodelling of potassium (K+) channel networks regulates skeletal muscle (SkM) excitability. Triiodothyronine (T3), locally generated from thyroxine (T4) by type 2 deiodinase (D2), binds thyroid hormone receptors (TRα/β) and modulates transcription via thyroid response elements (TREs).

Dynamical Environment and Stability around Centaur (2060) Chiron

The Astrophysical Journal
A recent stellar occultation revealed that the Centaur (2060) Chiron hosts a broad disk extending beyond ∼200 km from its center, embedding three ring-like structures (Chi1R, Chi2R, and Chi3R), while a tenuous outer ring (Chi4R) lies beyond the Roche ...

Enhanced Liver Fibrosis Test, FIB‐4 and FibroScan: Real‐World Prognostic Accuracy for MASLD in a Biopsy‐Controlled Cohort

Liver International, Volume 46, Issue 8, August 2026.
ABSTRACT Background and Aims Liver fibrosis is a major determinant of liver‐related events (LREs) in patients with metabolic dysfunction‐associated steatotic liver disease (MASLD). Effective stratification based on fibrosis severity is essential for accurate prognosis.

Head‐to‐head comparison of the diagnostic value of fecal and serum carcinoembryonic antigen for colorectal cancer detection

International Journal of Cancer, Volume 159, Issue 2, Page 516-525, 15 July 2026.
What's new? The diagnostic value of fecal versus serum carcinoembryonic antigen (CEA) for colorectal cancer detection remains unclear. This study provides a head‐to‐head comparison of serum and fecal CEA using matched samples from two large colorectal cancer screening studies and two fecal sample processing methods.
