Highlights

● Two novel electrodes (one with circle surface and the other with square and arched surface) were designed for radiofrequency intestinal anastomosis, and their effects were compared to a control electrode (smoot surface).

● The temperature and thermal damage to tissue produced by the two designed electrodes during welding are lower than those by the control electrode. 

● The electrode with square and arched surface has a smaller effective welding area and better effect on intestinal anastomosis.

Highlights

● A strong positive correlation was identified in the investigation of the relationship between contact force and irreversible electroporation (IRE) efficacy for tissue ablation. 

● This research conducted on potato models highlights the importance of optimizing electrode contact force in IRE for applications in atrial fibrillation treatment.

● Our findings provide insights into the design of advanced IRE ablation protocols and facilitate the clinical development and translation of this technology for effective atrial fibrillation treatment.

Highlights

● Near-infrared spectroscopy (NIRS) technology transmits a beam of near-infrared light through a transmitter to the brain. 

● The changes in hemoglobin concentration and cerebral blood oxygen levels can be estimated using near-infrared light, by comparing the changes in light attenuation over time.

● This paper introduces the basic concept of measuring blood oxygen levels in brain tissue using NIRS technology, and presents the potential applications of the most recent developments in this field of study.
