OBJECTIVE Microwave ablation is a minimally invasive technique that has been used to treat benign and malignant tumors of liver, lung and kidney. Towards thyroid nodules, only a few cases are reported so far. The aim of the study was to investigate the effectiveness and safety of ultrasound-guided percutaneous microwave ablation in the treatment of benign(More)
Oxidative stress induced by reactive oxygen species (ROS) plays crucial roles in a wide range of physiological processes and is also implicated in various diseases, including cancer, chronic inflammatory diseases, and neurodegenerative disorders. Among the various ROS, hypochlorous acid (HOCl) plays as a powerful microbicidal agent in the innate immune(More)
Hypochlorite (OCl(-)) plays a key role in the immune system and is involved in various diseases. Accordingly, direct detection of endogenous OCl(-) at the subcellular level is important for understanding inflammation and cellular apoptosis. In the current study, a two-photon fluorescent off/on probe (PNIS) bearing imidazoline-2-thione as an OCl(-)(More)
We designed and prepared the imidazoline-2-thione containing OCl(-) probes, PIS and NIS, which operate through specific reactions with OCl(-) that yield corresponding fluorescent imidazolium ions. Importantly, we demonstrated that PIS can be employed to image OCl(-) generation in macrophages in a co-culture system. We have also employed two-photon(More)
We developed a colorimetric and fluorescent turn-on carbon dioxide sensor that relies on a polydiacetylene, PDA-1, functionalized with amines and imidazolium groups. The pendant amines react with CO2 under basic conditions to form carbamoate anions, which partially neutralize the polymer's positive charges, inducing a phase transition. PDA-1 allows for the(More)

In this study, the ensemble of pyrocatechol violet and Sn(4+) was used for dopamine detection in a neutral aqueous solution with high selectivity and sensitivity. The detection course showed three color changes, which could be observed by the naked eye. We also demonstrated that this ensemble can be used to monitor tyrosinase activity.
In the current study, we report the first example of polydiacetylenes (PDAs), where our PDA-based system acts as both a sensing probe and killer for bacteria. The contact of imidazolium and imidazole-derived PDA with various bacterial strains including MRSA (methicillin-resistant Staphylococcus aureus) and ESBL-EC (extended-spectrum β-lactamase-producing(More)
