Analysis of Stochastic Nature and Shock Wave Pressure of Pulsed Spark Discharge in Saline With Auxiliary Pre‐Electrolysis Pulse

open access: yesHigh Voltage, Volume 11, Issue 2, Page 472-481, April 2026.
ABSTRACT Intravascular lithotripsy through liquid‐phase discharge is of great significance in improving the success rate of intravascular stent placement and treatment of severely vascular calcific plaque lesions. However, pre‐breakdown delay in intravascular lithotripsy system discharge has strong stochastic nature for the same high voltage discharge ...

Reirradiation for Recurrent Cervical Cancer Within the Previous Radiation Field Using a Bioabsorbable Spacer: A Case Report

open access: yesJournal of Obstetrics and Gynaecology Research, Volume 52, Issue 3, March 2026.
ABSTRACT Reirradiation for cervical cancer recurrence in previously irradiated fields is challenging due to dose limitations. To our knowledge, this is the first case report describing successful reirradiation using a bioabsorbable spacer for vaginal cuff recurrence after initial concurrent chemoradiotherapy (CCRT) and hysterectomy. A 70‐year‐old woman
