General description
碘化钠是一种无机钠盐，通常在有机合成中用作碘离子的来源。通过亲核位移反应将烷基卤化物和磺酸盐转化为烷基碘化物和芳基碘化物。此外，NaI 还与氧化剂结合使用，用于有机硼烷、酚类和芳香族化合物的碘化。

Many cases of unexpected radioiodine uptake have been reported, including physiological uptake in healthy tissue and in both benign and malignant nonthyroidal lesions. However, iodine uptake in the uterus has not been well assessed. In this article, we systemically analyzed

Thyroid hormone disorders have long been linked to depression, but the causal relationship between them remains controversial. To address this question, we established rat models of hypothyroidism using (131)iodine ((131)I) and hyperthyroidism using levothyroxine (LT4). Serum free thyroxine (FT4) and

The tumor-homing property of mesenchymal stem cells (MSCs) allows targeted delivery of therapeutic genes into the tumor microenvironment. The application of sodium iodide symporter (NIS) as a theranostic gene allows noninvasive imaging of MSC biodistribution and transgene expression before therapeutic
