Researchers used a substance to restore normal blood sugar metabolism in diabetic laboratory mice.

研究人员试图使用一种物质来恢复患有糖尿病实验老鼠在血糖方面的正常新陈代谢。

They began their experiments by feeding laboratory mice a fatty diet, to make them obese.

他们通过实验小鼠进行实验，喂养高脂肪食物，让它们长胖。

So, does this NMN therapy amount to a cure for diabetes in the laboratory mice?

那么，NMN的疗法是就能治愈所有实验鼠的糖尿病呢？

Using laboratory mice, they injected the animals with NMN in the hope of boosting the SIRT1 protein.

这些研究人员在实验鼠体内注入NMN，以期促进SIRT1蛋白质的合成。

Toward that end, the researchers have begun tests, again with laboratory mice, to investigate the result of long-term treatment with NMN.

为了验证上述问题，这些研究人员已再次开始对糖尿病小鼠的实验，以验证长期使用NMN对治疗的效果。

That is a significant fraction of the two to three years a healthy laboratory mouse might be expected to survive if it is not experimented on.

考虑到实验室中未受试的健康小鼠的预期寿命是2到3年，染毒小鼠获得延长的这部分存活期显得很显著了。

The researchers then exposed Thale cress--the plant biologist's version of the laboratory mouse--to the recorded vibrations while no caterpillars were actually present.

然后，研究人员将塔勒水芹（植物生物学家的实验室小鼠版本）暴露在记录的振动中，而实际上并没有毛毛虫存在。

Since, for obvious reasons, you can't run these tests on humans, toxicologists usually gets this number, often called the LD50, by using an endlessly unfourtunate creature: the laboratory mouse.

显然，疯狂科学家的时代已过，拿人类实验不太可能。毒理学家为了得到这个数值：简称为 LD50，主要是使用大批大批的无辜的实验室大鼠。

The study involved laboratory mice. It found that adult mice raised in a germ free environment were more likely to develop allergies, asthma and other auto immune disorders

这项研究使用了实验室老鼠。研究发现，成年老鼠在无菌环境中长大更容易出现过敏、哮喘和其他自体免疫紊乱。
