A robust molecularly imprinted electrochemiluminescence sensor based on a Ni-Co nanoarray for the sensitive detection of spiramycin.

To prepare portable and robust sensors for the sensitive and selective detection of small molecules is still a challenge for the study of electroanalytical sensors. Here, we developed a molecularly imprinted electrochemiluminescence sensor (MIECL) for the detection of spiramycin (SPI), a type of multi-component macrolide antibiotic. First, Ni-Co LDH nanoarrays were synthesized by a one-step hydrothermal method and then directly used as a sensing platform.

A novel molecularly imprinted electrochemiluminescence sensor based on cobalt nitride nanoarray electrode for the sensitive detection of bisphenol S.

A substitute for bisphenol A (BPA), bisphenol S (BPS) has endocrine disruptive and toxic effects and could pose potential risk on human health and the environment. Herein, we fabricated a sensitive molecularly imprinted electrochemiluminescence (MIECL) sensor for the determination of BPS. CoN nanoarray with outstanding electrical conductivity was prepared and it directly served as the sensor platform.

Ultrasonography-guided radiofrequency ablation combined with lauromacrogol sclerotherapy for mixed thyroid nodules.

Objective: To evaluate the safety and effectiveness of ultrasonography-guided radiofrequency ablation combined with lauromacrogol foam sclerotherapy for the treatment of mixed thyroid nodules.

Methods: One hundred and nineteen patients with benign mixed thyroid nodules were included in this study. In all patients, radiofrequency ablation was performed on the solid components of nodules, and the cystic areas of nodules were treated with aspiration, irrigation with lauromacrogol injection and foam sclerotherapy.

[Observation by color Doppler ultrasound on endothelium-dependent dilation of congestive heart failure treated with Kanli Decoction].

Objective: To observe the changes of endothelium-dependent dilation (EDD) of patients with congestive heart failure (CHF) before and after Kanli Decoction treatment.

Methods: Thirty-five CHF patients were treated with Kanli Decoction. We used color Doppler ultrasound to monitor the flow-mediated dilation (FMD), pulsatile index (PI), resistance index (RI), baseline blood flow (BF), ejection fraction (EF) before and after the treatment.
