原声例句
Crash Course 解剖生理学篇

So, thyroid hormone for the win, right? What's not to love?

所以,甲状腺激素是最棒的,对吗?还有啥理由不爱它呢。

科学60秒-科学美国人 2019年11月合集

As for fixing human hearts? Perhaps manipulating thyroid hormone levels could be a start.

那人类心脏能修复吗?也许可以从控制甲状腺激素水平开始。

Crash Course 解剖生理学篇

If there's too much thyroid hormone, they both decrease their own hormone production, to stop stimulating the thyroid.

如果甲状腺激素过多,它们都会减少自身的激素分泌,停止刺激甲状腺。

Osmosis-内分泌

This results in growth of the thyroid glands and stimulates the follicular cells to produce excess thyroid hormone.

这会导致甲状腺增生并刺激滤泡细胞,产生过量的甲状腺激素

科学60秒-科学美国人 2019年11月合集

Because when they added extra thyroid hormone to zebrafish's tanks, their tiny hearts were no longer able to regenerate.

因为当他们向斑马鱼鱼缸中加入额外的甲状腺激素时,斑马鱼的小心脏便不能再生了。

Osmosis-内分泌

Another primary cause is toxic nodular goiter where one or more follicles starts generating lots of thyroid hormone.

另一个原发病因是毒性结节性甲状腺肿,即一个或多个滤泡开始产生大量的甲状腺激素

Crash Course 解剖生理学篇

Like steroids, thyroid hormone is lipid-soluble, so it crosses the membrane of its target cell to bind inside the nucleus.

像类固醇一样,甲状腺激素是脂溶性的,所以它穿过靶细胞的膜与细胞核结合。

Osmosis-内分泌

Also anytime the thyroid gets inflamed or damaged there can be a large release of preformed thyroid hormones.

甲状腺发炎或受损,也可能大量释放预先形成的甲状腺激素

Crash Course 解剖生理学篇

That in turn reduces thyroid hormone levels in the blood, and slows down your metabolism again, before you get over-heated.

这反过来会降低血液中的甲状腺激素水平,并在你过热之前再次减慢你的新陈代谢。

Osmosis-内分泌

If it's due to a primary cause, TSH will be low, an unbound thyroid hormones will be high.

如果是原发性甲亢,TSH水平将会很低,未结合的甲状腺激素水平会变高。

甲状腺激素

三碘甲状腺素(T3)及四碘甲状腺素(T4)在体内的运作系统[5]
甲状腺素在单一甲状腺滤泡中的合成:[6]
- 甲状腺球蛋白在粗糙内质网中合成,并经由胞吐作用进入到甲状腺滤泡腔的胶质中。

-同时,钠-碘帮浦经由主动运输将碘离子(I-)由血液唧入细胞
-碘离子利用碘离子信道经由促进性扩散进入滤泡腔[7]
-碘离子(I-)在胶质中被甲状腺过氧化酶(thyroid peroxidase)氧化为碘元素(I0)
-碘元素(I0)碘化了球蛋白的酪胺酰基(约120个).
-随后,毗邻的酪胺酰残基两两结合
- 复合体经由胞吐作用进入到了滤泡腔
- 蛋白酶将复合体进行切割,发布T4和T3
T3的构造,左为结构式,右为填充模型。

甲状腺激素英语:thyroid hormones)是由甲状腺滤泡上皮细胞合成的酪氨酸碘化物。主要是四碘甲腺原氨酸(又名甲状腺素,缩写为T4)和三碘甲腺原氨酸(缩写为T3),此外,还有少量逆-三碘甲腺原氨酸(缩写为rT3)。注意,甲状腺分泌的激素除了甲状腺激素外,还有降钙素。由于降钙素是甲状腺滤泡旁细胞产生的,所以,不属于甲状腺激素的范畴。

T4和T3均有生理活性,区别在于作用时间和强度:T4活性低、起效较慢,但持续时间长;T3活性高、起效快,但持续时间短。体内研究显示,在细胞水平发挥生理作用的主要是T3;绝大多数T4需转化为T3之后才能发挥生理效应,从这个意义上讲,T4更像是一种前激素。

Thyroid hormone 甲状腺激素

The structural formula (left) and a space-filling model (right) of (S)-triiodothyronine (T3, also called liothyronine in the pharmaceutical industry)
The structural formula (left) and a space-filling model (right) of (S)-thyroxine (T4.)

The thyroid hormones, triiodothyronine (T3) and its prohormone, thyroxine (T4), are tyrosine-based hormones produced by the thyroid gland that are primarily responsible for regulation of metabolism. T3 and T4 are partially composed of iodine (see molecular model). A deficiency of iodine leads to decreased production of T3 and T4, enlarges the thyroid tissue and will cause the disease known as simple goitre. The major form of thyroid hormone in the blood is thyroxine (T4), which has a longer half-life than T3. In humans, the ratio of T4 to T3 released into the blood is roughly 20 to 1. T4 is converted to the active T3 (three to four times more potent than T4) within cells by deiodinases (5'-iodinase). These are further processed by decarboxylation and deiodination to produce iodothyronamine (T1a) and thyronamine (T0a). All three isoforms of the deiodinases are selenium-containing enzymes, thus dietary selenium is essential for T3 production.
