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开始。

Fifth, the symptoms are not attributable to the physiologic effects of a drugs or medication, or due to a medical condition like hyperthyroidism which creates an excess of thyroid hormone, which can sometimes cause symptoms of anxiety and worry.

，些症状不由药物、毒品生理作用引起，也并非由如甲状腺功能亢进等疾病导致；甲亢产生过量甲状腺激素，引起焦虑和担忧症状。

Autoimmune hepatitis also tends to be associated with other diseases, like Hashimoto's thyroiditis, where your immune cells attack your thyroid, and Grave's disease, where your thyroid overproduces thyroid hormones.

自免肝常与其它疾病伴发，比如桥本氏甲状腺炎，此时免疫系统攻击你甲状腺，还有导致甲状腺产生过多甲状腺激素Grave's病。

Rarely, in some people - usually young, often male - too much thyroid hormone can make circulating potassium levels drop and cause weakness.

甲状腺激素过量使循环钾含量下降，继而导致虚弱，通常出现在年轻男性身上，但很罕见。

Or like you start off by explaining it, okay, hypothyroidism, okay, it's obviously where you produce less thyroid hormone.

或者你开始解释，好，甲状腺功能减退，显然是你产生甲状腺激素较少。

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水将很低，未结合甲状腺激素水高。

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，它们都减少自身激素分泌，停止刺激甲状腺。

Thyroid hormone comes into play when it binds to receptors inside the nuclei of your muscle cells, triggering the transcription of DNA that makes the enzymes to break down that glucose.

当甲状腺激素与肌肉细胞核内受体结合时，它就发挥作用，触发脱氧核糖核酸转录，使酶分解葡萄糖。

A secondary cause of hyperthyroidism is when there's a healthy thyroid that generates a lot of thyroid hormone in response to a TCH-secreting tumor in the anterior pituitary.

甲亢一个继发性病因是健康甲状腺在垂体前叶TSH分泌性肿瘤作用下分泌过多甲状腺激素。

Too much thyroid hormone causes the body to race. Too little, and it slows to a crawl. Unchecked, either state can be fatal.

甲状腺激素过多导致身体处于亢奋状态。而甲状腺激素过少，身体慢慢得迟钝。如果放任不管，任何一种状态都可能致命。

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甲状腺激素时，斑马鱼小心脏便不能再生了。

And she was losing weight even though she was eating all the time, because the thyroid hormone was no longer regulating her metabolism properly.

即使她一直在吃东西，她体重也在下降，因为甲状腺激素不再正常调节她新陈代谢。

Hassen called the lab. He ordered tests to check the level of thyroid hormone in the sample. It was very high.

哈森打电话给实验室，要求化验样本中甲状腺激素含量。结果显示甲状腺激素含量非常高。

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甲状腺激素。

A different cause is a hyper functioning thyroid adenoma where the follicular cells start growing uncontrollably, forming a benign tumor that makes excess thyroid hormones.

另一个原因是功能亢进甲状腺腺瘤，即滤泡细胞生长开始不受控制，形成一个产生过量甲状腺激素良性肿瘤。

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，所以它穿过靶细胞膜与细胞核结合。

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

反过来降低血液中甲状腺激素水，并在你过热之前再次减慢你新陈代谢。

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

导致甲状腺增生并刺激滤泡细胞，产生过量甲状腺激素。

Secondary hypogonadism can be due to hypothalamus or pituitary gland dysfunction; either from an inability to produce gonadotropin-releasing hormone or luteinizing and follicle stimulating hormones, or suppression from other hormones, like prolactin or thyroid hormone.

继发性性腺功能减退症可由下丘脑或垂体功能障碍导致，既可能是促性腺激素释放激素、黄体生成素和卵泡刺激素生成能力低下，也可能是以上激素分泌受到了其他激素抑制，例如泌乳素或甲状腺激素。

That then travels down to the thyroid, finds its receptors, and slaps the gland to attention so it releases its own special thyroid hormone into the blood, where it can affect virtually every cell in your body.

然后向下到达甲状腺，找到它受体，并拍打腺体以引起注意，因此它将自己特殊甲状腺激素释放到血液中，在那里它几乎可以影响你身体中每一个细胞。
