Long-Term Longitudinal Computational Study of a Marfan Syndrome Patient After Hybrid Repair of Aortic Arch Dissection With Parallel Stent-Grafts.

Hybrid repair is a valuable alternative treatment for aortic arch disease in Marfan syndrome patients after proximal aorta replacement. This study aimed to investigate the long-term durability of this technique with the use of parallel stent-grafts and evaluate strategies to prevent abdominal aortic dilation. One Marfan syndrome patient who underwent hybrid aortic repair with parallel stent-grafts for arch dissection after the Bentall procedure was admitted.

Double-branched stent graft and four-stage deployment in total arch repair: safety and feasibility evaluation in porcine models.

Objectives: The primary objective of this research was to evaluate the safety and feasibility of an innovative double-branched stent graft system employing four-stage deployment technology for aortic arch repair in porcine models.

Methods: The double-branched stent graft system consisted of a proximal polyester artificial blood vessel, the main and double-branched stent grafts and a delivery system. We utilized 12 healthy pigs as experimental animals (6 per group).

Loganin alleviates myocardial ischemia-reperfusion injury through GLP-1R/NLRP3-mediated pyroptosis pathway.

Myocardial ischemia-reperfusion (I/R) injury is one of main pathological manifestations of cardiovascular outcomes related to NLRP3 inflammasome-mediated pyroptosis pathway. Loganin is an iridoid glycoside extracted from traditional Chinese medicines, which has multiple activities. However, the roles and mechanism of loganin in myocardial I/R injury remain largely unknown.

Design of Wideband GHz Electric Field Sensor Integrated with Optical Fiber Transmission Link for Electromagnetic Pulse Signal Measurement.

The detection of high frequency overvoltage and partial discharge is of great significance in evaluating the insulation condition of high-voltage power equipment. A wideband GHz electric field (E-field) sensor for electromagnetic pulse (EMP) signal measurement was proposed in this paper. An optical fiber transmission link was adopted in the design in order to implement high-voltage isolation and reduce electromagnetic interference during transmission.
