RTA‐408 Enhances Radiosensitivity and Inhibited Tumor Progression via JNK Pathway in Glioblastoma

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Glioblastoma (GBM) is an aggressive brain tumor with poor prognosis owing to its high invasiveness and resistance to therapy. RTA‐408, a synthetic triterpenoid and nuclear factor erythroid 2‐related factor 2 activator, exhibits anti‐inflammatory and anti‐cancer properties; however, its effects on GBM remain unclear. This study investigated the

Imaging malaria parasites across scales and time

Journal of Microscopy, EarlyView.
Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.

The Dual Role of the 16mer Motif Within the 3′ Untranslated Region of the Variant Surface Glycoprotein of Trypanosoma brucei

Molecular Microbiology, Volume 125, Issue 1, Page 67-79, January 2026.
A fully conserved 16mer motif is required in the silent VSG to trigger efficient silencing of the expression site (ES)‐resident VSG and a successful exchange of the VSG coat. ABSTRACT The variant surface glycoprotein (VSG) of African trypanosomes is essential for the survival of bloodstream form parasites.

Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method

High Voltage, Volume 10, Issue 6, Page 1464-1473, December 2025.
ABSTRACT Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed for lightning‐induced electromagnetic pulse (LEMP) simulation is verified using the rocket‐
