This is a risk for people taking warfarin, especially in large doses, without an overlapping rapid-onset blood thinner such as heparin or low molecular weight heparin.

这在服用华法林的患者中存在风险，尤其是当大量使用且没有叠加使用如肝素或低分子量肝素等速效血液稀释。

And the thing about molecules that work as drugs ... FABIO URBINA: Is they have a certain molecular weight range, they have certain properties.

至于用的分子… … FABIO URBINA：它们有一定的分子量范围吗？它们有一定的特性吗？

The chemical parameters that we used for instance it was the molecular weight of compound, or the fact that the compound possesses or not some functional groups.

Boevé：我们使用的化学参数例如是化合的分子量，或者化合具有或不具有某些官能团的事实。

And then we were trying everything possible in a very logical way, whether it was basically blood thinners, whether it was low molecular weight heparins to prevent clotting.

然后我们以一种非常合乎逻辑的方式尝试了一切可能的方法，无论是基本上是血液稀释， 还是低分子肝素来防止凝血。
