科学领域:
- 老年学是一门学科.
- 内分泌学 在内分泌学.
- 临床化学 临床化学
背景情况:
- 甲状腺功能表现出与年龄相关的差异,需要为最年长的老年人制定特定的参考范围 (RIs).
- 血清自由甲状腺素 (FT4),甲状腺素 (T4),自由三甲状腺素 (FT3),三甲状腺素 (T3) 和甲状腺刺激激素 (TSH) 的现有RI不适用于90岁以上的个人.
- 在了解百岁老人和最老的甲状腺激素水平方面存在差距.
研究的目的:

Functions of Thyroid Hormones
2.5K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Synthesis and Regulation of Thyroid Hormones
4.1K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
