Abstract

Maintaining a stable level of potassium is crucial for proper bodily function because even a slight imbalance can result in serious disorders like hyperkalemia and hypokalemia. Therefore, detecting and monitoring potassium ion (K+) levels are of utmost importance. Various biosensors have been developed for rapid K+ detection, with aptamer-based biosensors garnering significant attention due to their high sensitivity and specificity. This review focuses on aptamer-based biosensors for K+ detection, providing an overview of their signal generation strategies, including electrochemical, field-effect transistor, nanopore, colorimetric, and fluorescent systems. The analytical performance of these biosensors is evaluated comprehensively. In addition, factors that affect their efficiency, such as their physicochemical properties, regeneration for reusability, and linkers/spacers, are listed. Lastly, this review examines the major challenges faced by aptamer-based biosensors in K+ detection and discusses potential future developments. [ABSTRACT FROM AUTHOR]

20. Application of preoperative three-dimensional reconstruction combined with fluorescence imaging in simultaneous bilateral single-port thoracoscopic anatomical pneumonectomy.

Author

Zhang T, Song X, Liang B, and Cai Q

Abstract

We report a clinical case of preoperative three-dimensional reconstruction combined with fluorescence imaging in simultaneous bilateral single-hole thoracoscopic treatment of pulmonary nodules. Fluorescent staining is widely used in clinics to show the interface between lung segments, and there are many reports in the literature. Indocyanine green (ICG), fluorescent staining method has the advantages of no need for repeated lung inflation and short time consumption. Moreover, the development of imaging three-dimensional reconstruction technology also provides convenience for accurate positioning of anatomical structures. Finally, we think that the application of preoperative three-dimensional reconstruction combined with fluorescence imaging for simultaneous double-lung single-hole thoracoscopic pneumonectomy can quickly and clearly display the interface between lung segments, provide technical support for the operation, shorten the operation time, reduce intraoperative bleeding, and have relatively high safety, and may shorten the learning curve for the growth of clinical thoracic surgeons, which may be worth popularizing and applying., Competing Interests: None., (AJTR Copyright © 2023.)
