The clock oscillates at its own endogenous, or internal, period.

生物钟以自己内在周期运作。

Do you think my endogenous clock ticks faster than yours, Alice?

你觉得我生物钟比你走得快吗？

In addition to taking exogenous steroid medications, Cushing syndrome can also result from increased levels of endogenous cortisol.

除了服用外源性类固醇药物外，内源性皮质醇升高也会导致库欣综合征。

We get a release of the endogenous opioid system and that production of opioids gives us a high when we dance.

内源性阿片肽释放会让我们在跳舞不已。

Dopamine would still cue me to eat the food, but the wretched taste would blunt the rewarding endogenous opioid response.

吃饭，多巴胺系统仍会“激励”着我去吃那些同抹有香蒜沙司面包，但面包发出怪味也会“钝化”内源性阿片脑作出“奖励”反应。

The oral microbiota can be altered by a series of endogenous and exogenous factors such as diet, smoking, alcohol, antibiotic treatments or pregnancy.

口腔微生物群可一系列内源或外源性因素影响，例如饮食、吸烟、饮酒、抗生素治疗或怀孕。

The flavor of the pesto and bread combination released some endogenous opioids telling me that this stuff is really delicious, that I like it.

香蒜沙司和面包一起发出味道，使我大脑分泌出了一些内源性阿片肽，让我意识到这东西好吃。

It is called the porcine endogenous retrovirus (PERV), and this virus has the potential to cause a viral epidemic similar to HIV.

它称为猪内源性逆转录病毒 (PERV)，这种病毒有可能引起类似于 HIV 病毒流行。

Another strategy is using amantadine, which is also an antiviral medication that increases endogenous dopamine production, although the mechanism here is still being worked out.

另一种方法是使用金刚烷胺，一种可以增加内源性多巴胺生成抗病毒药物，尽管它药理机制还不完全清楚。

If that test is positive, the next step is to determine the exact cause of endogenous cortisol production, and ACTH plasma levels can be checked.

如果测试结果为阳性，那下一步是探查内源性皮质醇失常原因，可以检查血清促肾上腺皮质激素水平。

However, what's responsible for the actual sensation of pleasure and feeling of liking when the juice hits your tongue and goes down your throat is endogenous opioids.

然而，果汁流经口腔及食道所产生愉悦感，正起作用还是内源性阿片类物质。

Even though this results in less endogenous cortisol production, it still doesn't quite compensate for the huge levels of exogenous cortisol, and that causes Cushing syndrome to develop.

即便造成了内源皮质醇生成减少，这仍不能代偿高水平外源性皮质醇，并会引发库欣综合征。

Normally that should cause a decrease in serum cortisol levels, but if Cushing syndrome is caused by endogenous cortisol production, then the serum cortisol levels should remain unchanged.

一般来说，这会导致血清皮质醇水平降低，但如果库欣综合征是由内源性皮质醇制造产生，那么血清皮质醇水平应该保持不变。

These endogenous opioids would tell the monkey that drinking juice was pleasurable and rewarding, and then tell the dopamine system to take note of how to get the juice again.

这些物质会“告诉”猴子们，喝果汁非常爽，并“通知”它们多巴胺系统记住如何再次喝到果汁相关”技巧（知识）”。

Relative debilitation of yang is mainly caused by congenital deficiency, or postnatal malnutrition and endogenous impairment due to overstrain, or consumption of yang qi due to prolonged illness.

阴偏衰主要由于先天禀赋不足，或后天饮食失养和劳倦内伤，或久病损伤阳气所致。

Another common cause of endogenous Cushing syndrome is tumors of the adrenal glands that make excess cortisol - like adrenal adenomas, which are benign tumors, and adrenal carcinomas, which are malignant tumors.

另一种常见内源性库欣综合征原因是肾上腺肿瘤导致过多皮质醇分泌，比如肾上腺腺瘤，一种良性肿瘤，还有肾上腺癌，一种恶性肿瘤。

OK. So in response to the endogenous opioids telling me I like the pesto, the dopamine system took note of how to get the pesto and taught me to want the pesto.

所以，内源性阿片肤“告诉”我我喜欢香蒜沙司，作为响应，多巴胺系统“记下”如何获取香蒜沙司相关过程，并让我产生相应食欲。

So there isn't anything wrong with the clock but the clock ticks and oscillates at its own endogenous period just the same as if I were to put you in a dark cave.

全所以生物钟没有什么问题，生物钟会依旧以内在周期运作，就和把你放在黑暗山洞里一样。

A number of years ago, several of my colleagues came up with a hypothesis that potentially idiopathic hypersomnia was being caused by an endogenous substance that was turning on the activity of GABA-A receptors.

多年前，我几位同事提出了一个假设，即潜在特发性嗜睡症是由一种内源性物质引起，这种内源性物质会开启 GABA-A 受体活性。

Cushing syndrome can happen because of exogenous cortisol meaning that it comes from outside usually in the form of medications, or because of endogenous cortisol - meaning that the excess cortisol is made by the body.

库欣综合征可以由外源性皮质醇导致，就是说它是从外界来，一般由药物摄取；也可以由内源性皮质醇导致，也就是身体本身制造了过多皮质醇。
