Article Synopsis
- Gene expression analysis helps understand how genes work and how plants respond to their environment, but traditional methods can be expensive and slow.
- This study introduces a faster and cheaper method using a chemiluminescence system to measure gene expression in Arabidopsis, specifically focusing on a key nitrate transporter gene.
- The process involves growing genetically modified Arabidopsis seedlings in a nutrient solution, followed by monitoring luminescent signals after adding nitrate, allowing for efficient comparison of different plant genotypes and nutrient conditions.
Background: Visualizing the specific regions where atrial fibrillation (AF) is maintained is crucial for effective treatment, but it remains challenging in clinical practice. We aimed to address this challenge by developing a mapping approach focused on the cycle length (CL) and its gradient (CL-gradient).
Methods: In 105 patients undergoing initial ablation for persistent AF, pre-ablation CARTOFINDER data were utilized to create maps based on three indicators: (1) CL, the atrial frequency during AF calculated using CARTOFINDER; (2) Short CL, encompassing CLs within 5 ms of the minimum CL; and (3) CL-gradient, the CL range within a 6 mm radius.
A His-bundle (HB) capture threshold rise is still a significant concern in permanent His-bundle pacing (HBP). We present a case where an abrupt increase in HB threshold and loss of capture occurred even after 3.5 years of stable permanent HBP for an atrioventricular block.
