Inhibiting the deposition of N species on the catalyst surface for the targeted oxidation of NO to NO is still a great challenge. Herein, a La and O dual-defective LaMnO (2U-LMO) perovskite was fabricated using a urea-nonstoichiometric comodulation strategy, which achieved 97.6% NO oxidation efficiency at 210 °C and 300,000 h, and was also capable of nearly 100% targeted oxidation of NO to NO, as well as exhibited excellent stability and recyclability.

Background: Radioiodine (I) remnant ablation (RRA) has become a key step in the postoperative treatment of differentiated thyroid cancer (DTC). However, inadequate or excessive I is common using fixed activities. This study was designed to explore the feasibility of radioiodine uptake and thyroglobulin (RAIU-Tg)-guided RRA.

The quantitative relationship between iodine and glucose metabolism in metastases from differentiated thyroid cancer (DTC) remains unknown. Aim of the prospective study was to establish the value of F-FDG PET/CT in predicting I-avidity of metastases from DTC before the first radioiodine therapy. A total of 121 postoperative DTC patients with elevated stimulated serum thyroglobulin (ssTg) who underwent I adjuvant therapy or therapy after F-FDG PET/CT scan were enrolled.

Introduction: The immune colloidal gold (ICG) method of measuring thyroid-stimulating hormone (TSH) is a rapid and easy-to-perform test, allowing off-site measurements. This study compared the clinical utility of the first ICG-based qualitative and quantitative TSH test methods in China with the third-generation serum TSH assay used worldwide.

Methods: Fingertip and venous blood was collected within 30 min from 283 patients initially suspected of hypothyroidism.

We investigate the plasmonic analog of electromagnetically induced transparency (EIT) using two adjacent graphene-based Fabry-Perot (F-P) resonators side coupling to a nanoribbon waveguide. By the coupling mode theory in time and F-P resonant model, the destructive interference from the coupling of the two F-P resonators results in the EIT-like optical response. The induced peak and width of the transparency window can be dynamically manipulated by varying the coupling distance of the two resonators, and the transparent window is easily shifted by tuning the resonator length or the chemical potential of the graphene nanoribbon.

A plasmonic bandpass filter based on graphene is proposed and numerically investigated using the finite-difference time-domain method. The proposed filter has a very simple structure, including two graphene nanoribbon waveguides laterally coupled to a graphene ribbon resonator. The transmission efficiency can be tuned by altering the coupling distance between the ribbons.

It is well known that, haematogenous colon cancer metastases are most commonly found in the liver, less likely in the lungs through the paravertebral venous system and rarely in other organs. Sporadic clinical cases of colon cancer metastases to the abdominal wall, the thyroid or the adrenal glands have been reported. Here, we present an uncommon case of chest wall metastasis from colon cancer demonstrated with 2-fluoro [fluorine-18]-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT).

Objectives: To evaluate the diagnostic value of serum osteocalcin in the detection of bone metastases from differentiated thyroid carcinoma (DTC).

Design And Methods: Serum samples from DTC patients with (DTC BM+, n=19) or without bone metastases (DTC BM-, n=19), and matched healthy volunteers (n=30) were tested for serum osteocalcin with electrochemiluminescent immunoassay.

Results: Osteocalcin was higher in DTC BM+ than in DTC BM- patients (+35.
