Electrochemiluminscence Based Biosensors with AuNP Showing Catalytic ROS Generation

Proceedings, 2017
Electrochemiluminescence (ECL) has been a useful analytical tool for fields such as molecular biology, food analysis, and analytical chemistry. In situ generation of reactive oxygen species (ROS) by surface mediated catalysis works collaboratively with ...

α2,3‐Sialyltransferase (ST3Gal1) regulates endometrioid‐type epithelial ovarian cancer cell migration and invasion via VEGF‐R2/JAK2/STAT3 signaling cascades

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To investigate the role of ST3 β‐galactoside α‐2,3‐sialyltransferase 1 (ST3Gal1) and vascular endothelial growth factor receptor 2 (VEGF‐R2) in endometrioid‐type epithelial ovarian cancer (E‐OC) because aberrant α2,3‐sialylation mediated by ST3Gal1 and VEGF‐R2‐related angiogenesis is linked with tumor progression. Methods ST3Gal1 and

The utility of serum markers in the conservative management of placenta accreta spectrum (PAS) by leaving the placenta in situ in women with high‐grade PAS

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To investigate the association between serum markers and successful conservative management of patients with placenta accreta spectrum (PAS). Methods This was a retrospective case–control study where patients with high‐grade PAS between 2011 and 2025 undergoing conservative leaving the placenta in situ were included.

Photonics of DNA/ruthenium(II) complexes

Nanophotonics, 2018
In this review, we describe the investigation of a ruthenium [Ru(II)] complex-based, AC voltage-driven, electrochemiluminescent (ECL) device first. The ECL turn-on response time and intensity were dramatically improved by introducing the AC method.

Evaluation of the Application of Urea Dissociation Treatment to Reduce the False‐Positive Rate of ELISA for Syphilis Detection

Journal of Clinical Laboratory Analysis, EarlyView.
Exploring the application of urea dissociation treatment to reduce the false‐positive rate of ELISA for syphilis detection. From January 2023 to January 2024, seven false‐positive syphilis samples were collected from Xi'an Regional Medical Laboratory Centre as the experimental group, five positive specimens as the control group, and five negative ...

Extreme Heterophilic Antibody Interference in BNP Immunoassay: A Case Report and Systematic Investigation Protocol

Journal of Clinical Laboratory Analysis, EarlyView.
A 53 year‐old male with type 2 diabetes presented extremely elevated BNP (> 4000 pg/mL) but normal NT‐proBNP and cardiac function. Systematic verification confirmed severe heterophilic antibody (HAMA) interference in the BNP chemiluminescence immunoassay.
