Effects of vagus nerve stimulation and epilepsy surgery on antiseizure medication usage in pediatric patients with drug‐resistant epilepsy in the real world: A retrospective nationwide cohort study

Epilepsia Open, Volume 11, Issue 1, Page 240-249, February 2026.
Abstract Objective The long‐term effects of epilepsy surgery (ES) or vagus nerve stimulation (VNS) on antiseizure medication (ASM) usage and status epilepticus (SE) diagnosis in real‐world pediatric drug‐resistant epilepsy (DRE) populations remain unclear. This study aimed to provide a more comprehensive understanding of how VNS and ES affect ASM usage

Conformational Analysis and NMR Data Assignment of Taraxerone Isolated From Cnidoscolus aconitifolius (Chaya)

Magnetic Resonance in Chemistry, Volume 64, Issue 1, Page 146-159, January 2026.
We report the first complete NMR assignment of taraxerone, a pentacyclic triterpenoid isolated from Cnidoscolus aconitifolius (chaya). Using 2D NMR, DFT, and NBO analysis, we resolved spectral ambiguities due to high‐order couplings and signal overlap. Two Ring A conformers were identified and characterized.

A Comprehensive Review of Fundamental DC/DC Converters: Performance Analysis, Design Considerations, and Applications

IET Circuits, Devices &Systems, Volume 2026, Issue 1, 2026.
Nonisolated direct current (DC)–DC converters serve as critical building blocks in modern power management systems. The choice of the optimal topology among numerous options has a direct impact on the efficiency, size, and final cost of the system. This study presents a comprehensive and critical comparative analysis of five fundamental topologies—buck,
