ABSTRACT The capture and safe storage of radioactive iodine (129I or 131I) are of a compelling significance in the generation of nuclear energy and waste storage. Because of their physiochemical properties, Porous Organic Polymers (POPs) are considered to be one of the most sought classes of materials for iodine capture and storage. Herein, we report on the preparation and characterization of tw o triazine-based, nitrogen-rich, porous organic polymers, NRPOP-1 (SABET = 519 m2 g-1) and NRPOP-2 (SABET = 456 m2 g-1), by reacting 1,3,5-triazine-2,4,6-triamine or 1,4-bis-(2,4-diamino-1,3,5-triazine)-benzene with thieno[2,3-b]thiophene-2,5-dicarboxaldehyde, respectively, and their use in the capture of volatile iodine. NRPOP-1 and NRPOP-2 showed a high adsorption capacity of iodine vapor with an uptake of up to 317 wt % at 80 °C and 1 bar and adequate recyclability. The NRPOPs were also capable of removing up to 87% of iodine from 300 mg L-1 iodine-cyclohexane solution. Furthermore, the iodine-loaded polymers, I2@NRPOP-1 and I2@NRPOP-2, displayed good antibacterial activity against Micrococcus luteus (ML), Escherichia coli (EC), and Pseudomonas aeruginosa (PSA). The synergic functionality of these novel polymers makes them promising materials to the environment and public health. PMID:35173259 | DOI:10.1038/s41598-022-06671-0 View on the web Inoreader.

Leveraging Molecular Assays to Aid Decision-making in Large Indeterminate Thyroid Nodules

xlomafota13 shared this article with you from Inoreader Leveraging Molecular Assays to Aid Decision-making in Large Indeterminate Thyroid Nodules Via JAMA Otolaryngology–Head & Neck Surgery Online First To the Editor We read with great interest the recently published article by Dublin et al in JAMA Otolaryngology–Head & Neck Surgery, where it was shown that for indeterminate nodules larger than 4 cm, the positive-predictive value of a genomic classifier test (ThyroSeq) was 50% and the negative predictive value (NPV) was 89%. These values were noted to be improved relative to the test's performance on smaller nodules. The authors point out that the 2015 American Thyroid Association guidelines suggest that total thyroidectomy may be preferred for indeterminate nodules that are large (>4 cm) to limit completion thyroidectomy and conclude from their analysis that thyroid lobectomy may be sufficient for genomic classifier-negative indeterminate nodules.
