A 93, a 95, a 97 and especially something that would help me again more on the backand side this time around because obviously I felt the pain sometimes from Rafael with his lefty spin going high into my back end.

93、95、97拍面的拍子我都尝试了，特别是一些能辅助我后方和侧面的东西，我也用了，因为很明显，纳达尔用左旋打到我后方时，再接球的话有时会让我感到很疼。

Many contain other legal stimulants like taurine, guarana and L-carnitine.

许多含有他合法兴奋剂，如牛磺酸、瓜拉纳和左旋肉碱。

66.do you have righ-hand or left-hand propeller ?

我们船在推时进时螺旋桨是右旋还是左旋？

But when the same people were given antibiotics to kill their gut microbes, a subsequent steak meal produced little TMAO, even though their carnitine levels went even higher than before. Production of TMAO, then, seems to need bacteria.

但当同一组志愿者服用杀死肠道微物后，之后的牛排大餐仅仅产了少量的TMAO，即使左旋肉碱水平比之前更高了。这说明产TMAO要细菌参与。

Peripheral dopa decarboxylase also exists, which can metabolize levodopa into dopamine before it gets through the blood brain barrier, and—via additional enzymes— metabolize it into other catecholamines like epinephrine, which can cause unwanted side effects like arrhythmias.

体内还有外周多巴脱羧酶，可以在左旋多巴穿血脑屏障前将转换为多巴胺；然后，他酶将转换为他儿茶酚胺，如肾上腺，它可以导致不良的副作用，如心律失常。

So the other thing about TMAO to know is that certain types of gut bacteria metabolize choline and carnitine into TMAO whereas others don't.

另外要了解的是，某些肠道菌群可将胆碱和左旋肉碱代谢成氧化三甲胺，另一些肠道菌群则不能。

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。

There's Glycine Propionyl L-Carnitine, aka GPLC, suggested that, in high dosages, improves blood pressure via increased nitric oxide production.

甘氨酸丙酰左旋肉毒碱 (GPLC) 表明，高剂量可以增加一氧化氮的产来改善血压。

On entering Yonville she made her horse prance in the road. People looked at her from the windows.

一走上荣镇的石板地，她就调动马头，左旋右转。 大家都在窗口看她。

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。

COMT inhibitors like entacapone and tolcapone are only given with levodopa to prevent the enzyme from breaking it down outside the central nervous system, thus allowing more of it to enter the brain.

COMT抑制剂，例如恩他卡朋和托卡朋与左旋多巴一起用于治疗，只是为了防止左旋多巴在中枢神经系统外被分解，从而使更多左旋多巴进入脑中。

And then there's L-Carnitine L-Tartrate, or LCLT, the form used mostly in performance and fitness research thanks to its more rapid absorption rate compared to the other two.

还有左旋肉毒碱酒石酸盐，简称 LCLT，这种形式主要用于性能和健康研究，因为它比他两种吸收速度更快。

To find out whether all this matters, Dr Hazen looked at the association between heart disease and levels of carnitine and TMAO in more than 2,500 people.

为了确认所有这一切正是问题的关键，Hazen博士调查了2500多人，以寻找心脏疾病与左旋肉碱和TMAO水平之间的关联。

Motor symptoms respond to drugs used to treat Parkinson's disease, like levodopa, a dopamine analogue, while cognitive symptoms may improve with drugs for Alzheimer's disease, like donepezil, which increases acetylcholine availability.

针对运动障碍，可使用与帕金森病类似的药物，比如多巴胺类似物左旋多巴，而使用类似阿尔茨海默病的药物，可以改善认知症状，比如多奈哌齐，它能增加乙酰胆碱的供给。

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。

Acetyl-L-Carnitine, or ALCAR, claimed to provide cognitive preservation in the elderly as well as provide potential anti-aging properties.

乙酰左旋肉毒碱，或称 ALCAR，这种物质声称能保护老年人的认知能力，并具有潜在的衰老特性。

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.

多巴胺本身不能血脑屏障，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，尤是在残存的黑质纹状体神经元内。

He found there was indeed an association between heart disease and carnitine, but only when TMAO levels were also high.

他发现，心脏疾病与左旋肉碱确有关联，但只有高TMAO水平时才会发。

Regardless of the details, though, this study suggests that people looking for the link between heart disease and the eating of meat have been ignoring two culprits, carnitine and bacteria.

虽然细节存疑，该研究也表明，人们长久以来一直在寻找心脏疾病与肉食之间的关联，却忽略了两个祸首：左旋肉碱与细菌。

This is exactly why levodopa is administered with carbidopa, a dopa decarboxylase inhibitor that isn't able to cross the blood-brain barrier.

这也就是左旋多巴要和卡比多巴共用的原因；卡比多巴是一种不能血脑屏障的多巴脱羧酶抑制剂。
