This design improves the body force and induced jet velocity while allowing flexible control of the induced jet angle, overcoming the limitations of discharge extension and uncontrollable direction in traditional DBD plasma actuators. An integrated plasma power supply has been designed specifically for TES-DBD plasma actuators, streamlining the power supply management. The methodology involves designing the circuit topology for the TES-DBD power supply, followed by simulating and validating its operating principles using Multisim software. The operational performance of the power supply is evaluated through a comprehensive analysis of its electrical,thermal, and aerodynamic properties specific to TES-DBD plasma actuation.展开更多

Previous studies have found that γδT cells play a dual role in tumor immunology: tumor-promoting and tumor-controlling.The anti-tumor therapy of γδT cells has made remarkable success in clinical application. Especially in recent years, researchers have provided some novel effective ways such as γδT cells exosomes and adoptive chimeric antigen receptor-γδT cells immunotherapy. However, some problems remain to be solved, such as low expansion rate, poor targeting, and tumor microenvironment limiting the effectiveness of γδT immunotherapy. Traditional Chinese medicine is expected to play a positive role in the body immune-enhancing function, promoting the proliferation and activation of γδT cells, and inducing the differentiation ofγδT cells. In this review, we summarize the recent research progress and urgent problems of γδT cells in anti-tumor immunotherapy. Moreover, some new strategies of γδT cells for tumor immunotherapy were proposed.展开更多

However, irrigant selection or irrigation procedures are far from clear. The vapor lock effect in the apical region has yet to be solved, impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.展开更多
