Article Synopsis
  • The study introduces a new dual-potential ratiometric electrochemiluminescence (ECL) sensor for detecting carcinoembryonic antigen (CEA), using a single emitter (luminol) and coreactant (hydroxyl radicals) within a mild potential range.
  • The sensor works by measuring the changes in ECL intensity as CEA affects the oxidation and reduction reactions of luminol and hydroxyl radicals, leading to significant variations in the detected signals.
  • This innovative approach allows for sensitive CEA detection with a limit of detection (LOD) of 41.85 fg/mL, while also showcasing strong performance in specificity, stability, and reproducibility during practical tests.

Post-stroke dysphagia (PSD) is a common and costly complication of stroke and is associated with increased mortality, morbidity, and hospitalization. Although most patients can spontaneously resume swallowing, there are still many patients who do not recover and even die. Despite multiple advances in the acute treatment and secondary prevention of stroke, the effective treatment of PSD remains a neglected area.

Patients with hepatocellular carcinoma (HCC) exhibit a high incidence of concomitant cirrhosis with leukopenia and/or thrombocytopenia. In the present study, perioperative changes in the white blood cell (WBC) and platelet (PLT) counts and associated complications were investigated to assess the safety of transcatheter arterial chemoembolization (TACE) for HCC patients with preprocedural leukopenia or thrombocytopenia. The records of 1,461 HCC patients who received TACE between January 2012 and December 2013 were retrospectively reviewed.

Percutaneous ethanol injection is an important localized treatment method for patients presenting with hepatocellular carcinoma (HCC). Among the advantages of percutaneous ethanol injection are its minimal invasiveness, simplicity, low cost and low risk of complications. However, the increasing popularity of percutaneous ethanol injection has resulted in serious adverse effects attributed to individual variations.

Objective: Clinical trials suggest that combining transcatheter arterial chemoembolization with sorafenib in patients with advanced hepatocellular carcinoma shows a superior safety and tolerability profile. Our study aimed to retrospectively analyze the utility and prognostic factors of this combined therapy in these patients.

Methods: Patients with advanced hepatocellular carcinoma, treated by transcatheter arterial chemoembolization and sorafenib subsequently, between February 2010 and September 2012 in our hospital, were retrospectively analyzed.

Objective: To establish a highly sensitive fluorometric nanobiosensor for determination of aqueous mercury ions (Hg(2+)) using optimized mercury-specific oligonucleotide (MSO) probes and graphene oxide (GO).

Methods: The nanobiosensor was assembled by attaching the self-designed MSO(1) (5' end labeled with fluorophore carboxyfluorescein (FAM), denoted as FAM-MSO(1)) and MSO(2) to the surface of GO through strong non-covalent bonding forces. Upon the addition of Hg(2+), the formation of the T-Hg(2+)-T configuration desorbed the FAM-MSO(1) and MSO(2) from the surface of GO, resulting in a restoration of the fluorescence of FAM-MSO(1).
