Functional materials with organic/inorganic composites as the main matrix and rare earth ion complexes as the guest have shown a very broad application prospect for antibiotic sensors. However, Eu-complex often relies on a single fluorescence response signal, which is susceptible to changes in the detection environment and cannot simultaneously detect and remove tetracycline (TC). Herein, green fluorescent covalent two-dimensional organic framework (COF-TD) is synthesized, followed by modification of Eu to synthesize COF-TD@Eu.

- The study explores charge transport mechanisms in glutathione-stabilized gold nanoclusters (GSH-Au NCs), focusing on the interplay between electron transfer and aggregation induction effects while sensing metal ions.
- A dual-channel sensing method combining fluorescence and second-order Rayleigh scattering is introduced, enabling high-throughput classification of metal ions like Pb, Ag, and Cu through distinctive signal behavior.
- The research demonstrates successful detection of multiple metal ions in real water samples, employing advanced analysis techniques and achieving a low detection limit, while also introducing a novel approach for information encoding using GSH-Au NCs.
Background: In tumor treatment, protein tyrosine kinase inhibitors (TKIs) have been extensively utilized. However, the efficacy of TKI is significantly compromised by drug resistance. Consequently, finding an effective solution to overcome TKI resistance becomes crucial.

Bronchial methylene blue staining was developed by our team in 2015 and is now commonly used at our center, it could rapidly and accurately identify the ISP. In this study, we aimed to compare bronchial methylene blue staining with the modified inflation-deflation method in terms of their perioperative characteristics and to present our experience of the methylene blue method.

Objective: To investigate the expression of protein kinase B (PKB) in human-squamous cell carcinoma (SCC) and adenocarcinoma of lung (ADC) and in benign lung tissues (BD, lung tissues adjacent to cancer or from patients with benign lung diseases), and its association to clinicopathological characteristics.
Methods: The PKB expression in 41 specimens from patients with SCC (26 cases) and ADC (15 cases) and in 12 specimens from patients with benign lung diseases (BD) were investigated by immunohistochemistry and Western blot analysis.
Results: PKB in benign lung tissues was usually weakly stained and scattered in distribution.
