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

生物钟以自己的内在周期运作。

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？

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

除了服用性类固醇药物，内性皮质醇的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.

内性阿片肽的释放会让我们在跳舞时兴奋不已。

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”内性阿片脑作出的“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.

微生物群可一系列内性因素影响，例如饮食、吸烟、饮酒、抗生素治疗怀孕。

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的味道，使我的大脑分泌出了一些内性阿片肽，让我意识到这东西真的很好吃。

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

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

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，一种可以增加内性多巴胺生成的抗病毒药物，尽管它的药机制还不完全清楚。

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。

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，果汁流经及食道时所产生的愉悦感，真正起作用的还是内性阿片类物质。

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.

即便造成了内皮质醇生成减少，这仍不能代偿高水平的性皮质醇，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性皮质醇制造产生的，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”它们的多巴胺系统记住如何再次喝到果汁的相关”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，后天饮食失养和劳倦内伤，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.

另一种常见的内性库欣综合征的原因是肾上腺肿瘤导致过多的皮质醇分泌，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。

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。

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，我的几位同事提出了一个假设，即潜在的特发性嗜睡症是由一种内性物质引起的，这种内性物质会开启 GABA-A 受体的活性。

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.

库欣综合征可以由性皮质醇导致，就是说它是从界来的，一般由药物摄取；也可以由内性皮质醇导致，也就是身体本身制造了过多的皮质醇。
