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

生物钟以自己的内在周期运作。

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”如何获取香蒜沙司的相关过程，并让我产生相应的食欲。

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

口腔微生物群可被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。

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.

造成了内源皮质醇生成减少，这仍能代偿高水平的外源性皮质醇，并会引发库欣综合征。

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.

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的抗病毒药物，尽管它的药理机制全清楚。

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

内源性阿片肽的释放会让我们在跳舞时兴奋已。

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

你觉得我的生物钟比你的走得快吗？

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”它们的多巴胺系统记住如何再次喝到果汁的相关”技巧（知识）”。

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的原因，可以检查血清促肾上腺皮质激素水平。

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的周期运作，就和把你放在黑暗的山洞里一样。

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的，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的皮质醇。

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的味道，使我的大脑分出了一些内源性阿片肽，让我意识到这东西真的很好吃。

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的，那么血清皮质醇水平应该保持变。

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

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

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时所产生的愉悦感，真正起作用的是内源性阿片类物质。

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.

一种常见的内源性库欣综合征的原因是肾上腺肿瘤导致过多的皮质醇分，比如肾上腺腺瘤，一种良性肿瘤，有肾上腺癌，一种恶性肿瘤。

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，内源性皮质醇的升高也会导致库欣综合征。

It can be exogenous, meaning drug-related, or endogenous, meaning that it's from an adrenal tumor or excess ACTH from a pituitary adenomas, in which case it's called Cushing disease or from an ectopic site like small cell lung cancer.

它可以是外源性，也就是药物相关；或内源性，也就是由肾上腺肿瘤或由垂体腺瘤分过多ACTH造成，这种情况下叫做库欣病，或是源于异位分，比如小细胞肺癌。

In fact, these endogenous retroviruses, as they're known, make up about 8% of our genome.

事实上，这些被称为内源性逆转录病毒的古老DNA序列，约占我们基因组的8%。

So the number of candidates in this model is going to be endogenous.

因此，该模型中的候选人数量将是内生的。
