The mismatch in question revolves around a molecule called carnitine.

疑问的焦点集中于种称为左旋肉碱的分子。

This diet resulted in high levels of both carnitine and TMAO in the volunteers' blood.

该食谱使得志愿者血液中的左旋肉碱和TMAO都处高水平。

That suggests the vegan's particular gut flora—adapted to his usual meat-free diet—did not contain species that can digest carnitine.

这表明素食者特殊的肠道菌群――适应了他的无肉饮食――不含有可消化左旋肉碱的种类。

The principal difference they found turned out to be levels of L-DOPA.

他们发现的主要区别于左旋多巴的水平。

Alright the next dopamine-directed class of therapies are inhibitors of COMT, catecholamine-O-methyltransferase, which is an enzyme that degrades dopamine and levodopa.

个针对多巴胺的治疗药物是COMT抑制剂；COMT，即儿茶酚胺-O-甲基转移酶，是种可以降解多巴胺和左旋多巴的酶。

And observing a left spinning particle on one side of the world would make the other particle on the other side spin right.

世界的侧观察个左旋的粒子会使另侧的另个粒子右旋。

Less commonly, babies can have levo-transposition of the great arteries, or l-TGA, with levo meaning that the aorta's primarily to the " left" of the pulmonary artery.

更少见地，宝宝可能会有左旋-大动脉转位，即L-TGA，左旋的意思是主动脉主要位于肺动脉的左侧。

They're right–handed with only rare exceptions, and when by chance a shell's spiral is left–handed, collectors will pay its weight in gold for it.

除了极少数例外， 它们都是右旋的，当碰巧贝壳的螺旋是左旋的时，收藏家会花上同等重量的黄金来买它。

Experiments in mice confirmed the broader hypothesis: TMAO production relies on microbes that digest carnitine, and prolonged consumption of that chemical by susceptible mice leads to atherosclerosis.

产生TMAO需要能消化左旋肉碱的细菌参与，易患病的老鼠如果长期食用左旋肉碱会导致动脉粥样硬化。

Dopamine itself can't cross the blood-brain barrier, but its precursor levodopa can, and once in the brain, levodopa is converted to dopamine by dopa decarboxylase, most importantly within the remaining nigrostriatal neurons.

多巴胺本身不能通过血脑屏障，但它的前体左旋多巴可以，旦进入脑中，左旋多巴就会被多巴脱羧酶转换为多巴胺，尤其是残存的黑质纹状体神元内。

Leads I and aVL, along with two of the chest leads, V5 and V6, are all considered " lateral" leads and they're near the lateral wall of the heart which receives blood from the left circumflex artery.

I、aVL以及V5和V6导联，被认为是“侧壁导联”，因为它们靠近心脏的侧壁，这里接受左旋支动脉的血液供应。
