Doctors implanted a pig heart in 57-year-old Bennett in January.

今年 1 月，医生为 57 岁的班尼特植入了一颗猪心脏。

Pig heart valves have been used successfully for many years in humans.

猪的心脏瓣膜已被成功用于人类治疗很多年了。

They also removed another gene in an effort to prevent too much growth of pig heart tissue.

他们还移除了另一个基因，以防止猪心脏组织过度生长。

An NYU team has also tested transplanted pig hearts on donated bodies for three days of intense testing.

纽约大学的一个研究小组也在捐赠的遗体上对移植的猪心脏进行了为期三天的密集测试。

They also removed another gene from the animal in an effort to prevent too much growth of pig heart tissue.

他们还从猪身上移除了另一种基因，以防止猪心脏组织过度生长。

So we now know that a baboon can keep a pig heart alive.

所以我们现在知道狒狒可以让猪的心脏保持活力。

So, successfully transplanting a pig heart into a baboon suggests that the new technique would also work on humans.

因此，成功地将猪心脏移植到狒狒体内表明这项新技术也适用于人类。

The next step is to find out if a pig heart can do the same thing for a baboon.

下一步是找出猪心是否可以为狒狒做同样的事情。

So for years, scientists have been trying to figure out how to transplant pig hearts into humans.

因此多年来，科学家们一直在试图弄清楚如何将猪心移植到人体中。

And earlier this month, doctors at University of Maryland School of Medicine in Baltimore transplanted a pig heart into a living human patient.

本月早些时候，巴尔的摩马里兰大学医学院的医生将一颗猪心移植到一位活着的患者体内。

Back in early 2022, a team at the University of Maryland transplanted a pig heart into a living person-a man named David Bennett.

早在2022年初，马里兰大学的一个研究小组就将一颗猪的心脏移植到了一个活人身上——这个接受移植的人叫大卫·贝内特。

In January, surgeons at the University of Maryland School of Medicine transplanted a pig heart into a man with terminal heart disease.

1 月，马里兰大学医学院的外科医生将猪心脏移植到一名患有晚期心脏病的男子体内。

On the morning of the surgery, the transplant team removed the pig's heart and placed it into a special device to keep it running until the operation.

手术当天上午，移植团队取出了这头猪的心脏，并将其放入一个特殊的设备中，使其直到手术结束一直保持跳动。

Pig hearts and human hearts actually have a lot in common: They each have four chambers, four valves, and they're about the same size.

猪心和人的心脏实际上有很多共同点：它们都有四个腔室、四个瓣膜，而且大小差不多。

In January of 2022, for the first time in history, a team at the University of Maryland Medical Center, transplanted a genetically modified pig heart into a living human being.

在2022年1月，有史以来第一次，马里兰大学医学中心的一个团队，将转基因猪的心脏移植到活人体内。

But we know from decades of primate work, when the organ… when the pig heart is infected with that virus, that it causes the heart to start to go rapidly downhill.

不过，我们从几十年的灵长类动物研究中了解到，当猪的器官--猪的心脏感染了这种病毒，会导致心脏开始迅速坏死。

But this week, the National Heart, Lung, and Blood Institute announced that scientists have managed to successfully keep pig hearts alive in baboons for over a year.

但本周，美国国家心肺血液研究所宣布， 科学家们已经成功地让猪心在狒狒体内存活了一年多。

They're not there yet, but have made a few steps towards their goal like having a pig's heart stay alive in a baboon's stomach for over 2 and a half years.

他们还没有达到这个目标，但已经朝着目标迈出了几步，就像猪心在狒狒胃里存活了两年半多一样。

But we know from decades of primate work, when the organ ... when the pig heart is infected with that virus, that it causes the heart to start to go rapidly downhill.

但我们从数十年的灵长类动物研究中知道，当器官… … 当猪的心脏感染了这种病毒时，它会导致心脏开始迅速恶化。
