The mismatch in question revolves around a molecule called carnitine.

疑问的焦点集中于一种称为左旋肉碱的分子。

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――适了他的无肉饮食――不含有可消化左旋肉碱的种类。

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

该食谱使得志愿者液中的左旋肉碱和TMAO都处在高水平。

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

下一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，是一种可以解多巴胺和左旋多巴的酶。

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

他们发现的主要差异最终在于左旋多巴的水平。

I've responded very well to any sort of like acetylalcarnitine oral form has worked really well for me.

我对任何类型的乙酰左旋肉碱口服制剂都有很好的反。

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 were randomly assigned to receive either levodopa carbidopa or a matched placebo three times daily for 39 days, along with standardized rehabilitation therapy.

他们被随机分配， 接受为期39天、每日三次的左旋多巴-卡比多巴或匹配的安慰剂治疗，同时配合标准化的康复疗法。

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.

对老鼠进行的实验证实了进一步的猜想：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。

In most cases, when it comes to that left-hand versus right-hand thing, The molecule cannot just easily go from the left-hand version to the right-hand version.

在大多数情况下， 当涉及到左旋和右旋的问题时，分子不能轻易地从左旋形式转变为右旋形式。

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脑屏障，但它的前体左旋多巴可以，一旦进入脑中，左旋多巴就会被多巴脱羧酶转换为多巴胺，尤其是在残存的黑质纹状体神经元内。

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”，因为它们靠近脏的侧壁，这里接受左旋支动脉的液供。
