Monitoring labile Zn2+ homeostasis is of great importance for the study of physiological functions of Zn2+ in biological systems. Here we report a novel ratiometric fluorescent Zn2+ sensor, CPBT, which was constructed based on chelation-induced alteration of FRET efficiency. CPBT was readily cell membrane permeable and showed a slight preferential localization in the endoplasmic reticulum. With this sensor, 3D ratiometric Zn2+ imaging was first realized in the head of zebra fish larvae via Z-stack mode. CPBT could track labile Zn2+ in a

Therefore, we provide a clear understanding of compromised intestinal barrier induced by mycotoxins, with a view to potentially develop innovative strategies to prevent and treat mycotoxicosis. In addition, because of increased combinatorial interactions between mycotoxins, we explore the interactive effects of multiple mycotoxins in this review.The aim of this study is to compare root-end preparation performed with two different ultrasonic tips-CVDentus and NSK-and respective time requirements. After root-end resection, 32
