可能永远年轻吗

Is It Possible To Stay Young Forever?

大家好 欢迎来到品生活
Hey, there. Welcome to Life Noggin.
变老是一个生理过程 对吧?
Growing old is a fact of life or is it?
要是我告诉你 我们是有可能永葆青春的
what if I told you that is possible to stay young forever
不是啦 这只是我新的外观宣言提供的一些参考
No this is some informercial for my new cosmetic’s line
像素下的面孔 尽管我的皮肤实际上不像我说得那么光滑
Pixel face though my skin doesn’t look flow as if I do say so myself
不对 我说的是生理上永葆青春
No. I’m talking about biologically staying young forever.
现代科学正在走向实用性
It’s modern science navigating its way to the fountain of use
带上你的麻烦
grab your cumbersome
好了 我们将去探寻答案
Well, we’re gonna find out.
让我们先来看看人类为什么会变老
Let’s start by looking at why we age at the first place
DNA复制过程发生错误
When your DNA replicates mistakes can be made
这些错误会导致DNA序列改变
that leads to changs of the DNA sequence
通常这些问题是可以解决的
these mistakes are usually fixed
但有时候却会变成一个裂缝
But sometimes they slip to the cracks
导致DNA破坏
leaving your DNA damaged
这个缺陷直接导致了衰老
and this decay has been directly linked to aging
如果受损太严重
if the damage gets too bad
拥有这条DNA的细胞就会死亡
This cell with that DNA will die
或者进入一个我们称之为衰老的过程
or enter to a process called Senescence
这就意味着DNA不会再复制了
which means it won’t replicate
这些不能再生的细胞可能会加速衰老过程
These nonreplicated cells may speed up the process of aging
通过释放炎症蛋白
by releasing inflammatory proteins
即使在它们的死亡休眠期 这些细胞还会消耗你体内的能量
even in their dead dormancy these cells wear down your internal economy
就好比上学时候 那些小霸王会一直抢你的零花钱
like that bully who keeps asking for your lunch money
得到三角形柱 可不是个游戏
Gain a trangle bar not a game
最糟糕的一种DNA损伤是在染色体端粒上
One of the worst forms of DNA damages is with your chromosomes’ Telomeres
端粒在我们染色体的尾部
Telomeres are at the end of your chromosome
是用来保护DNA的
which are protecting the DNA
每当细胞分离时 大多数端粒都会萎缩
Most Telomeres shrink every time their cell divides
一旦端粒变得很短 细胞就会死亡
And once they became too short, the cell dies.
或者变成那些无负荷的衰老细胞中的一员
or becomes one of those free loading senescence cells
房租到期了 哥们
The rent is due, buddy
所以 想要保持年轻 也许就要找到一个
So maybe a way to stay young is to simply find a way
能重新装载端粒的方法
to replenish the Telomeres
其实 身体里的每个细胞都有基因代码执行这项活动
Well, every cell in your body actually has the genetic code to do this
但是答案远不是这么简单
But the answer isn’t that simple
因为大多数细胞不会重新加载它们的端粒
Because most of your cells don’t replenish their Telomeres
来保护身体免于癌症
to protect the body from cancer.
你自身的线粒体也可能不发挥作用
Youselves’ mitochondria may also hold the secrets
来延缓衰老过程
for delaying the aging process
你还记得那些知识 对吧?和我一起读
You remember those, right? Say with me now.
线粒体是细胞的能量之家
” The mitochondria is the powerhouse of the cell.”
至少 这是我从高中学到的如今还记得的一个知识
At that least, that’s one thing I remember from high school.
还是不知道具体是怎么工作的 他们从没交过我
Still don’t know how this thing works, they never taught me.
不管怎样 似乎好像给线粒体适当程度的压力和氧化
Anyway, it seems as though the right amount of stress and oxidation
是永葆青春的关键
to your mitochondria is key to staying younger.
过去总担心 随意且彻底的破损线粒体
The fear use to be all the free radical damages to your mitochondria
会加速老化
would cause you to age faster
然而 据最新研究 给线粒体加压
However, due to recent study, stressing your mitochondrias
实际上 似乎延长了寿命
seems to actually extend your life span
这个前提是破损不太严重
This provide that the damage isn’t too serve
我猜测 没有将你打倒 实际上会让你变的更强大
I guess what doesn’t kill you truly does make you stronger.
但也许我们能从其它动物上学到点东西
But maybe we can learn something from another animal
比如永生的水母
like the immortal jellyfish
它的生存法则就是
As its survival method
水母可以做到返老还童
the jellyfish can live back to when they were a baby
它们通化转分化做到这一点
They do this through transdifferentiation
成年细胞能够转化成一个完全不同的细胞
where their adult cells can reverse back to an entirely different cells
但是反过来要是我们变成吸血鬼呢
But what if we just became vampires instead.
好吧 事实上它没那么科幻
Well, it’s actually less science fiction than you think
研究人员已经能够通过手术把幼鼠和成年老鼠结合在一起
Researchers were able to surgically join mice with younger ones
以便让他们共用血液循环系统
So that the pair share the same blood circulation
通过让幼鼠的血液流向成年老鼠的身体
by having the younger blood flow through their body
成年老鼠与老化相关的心脏状态完全改善
age related heart conditions in the older mice will be actually reversed
也许吸血鬼在这里发挥着什么作用吧
Maybe dracula was on the something here.
那么 你怎么看?你想永葆青春吗?
So what do you think? Would you wanna stay young forever
在下面留言给我吧

科学家们总是在探索新的方法
Scientists are always looking for new ways
来提高人类的寿命
to increase the life span of you humans
其中一个方法就是基因修补
One way is genetical modification
想知道工作原理 那你就看看这个视频
to learn how this works. Make sure you check out this vedio
秘密就在于组织器官的免疫系统
and the secrets are vital to that organism immune system
假如病毒入侵细菌细胞
See if virus invades bacteria cell
病毒一般是基因单元或者完整的一条DNA
that viruses are genels or complete set of DNA
DNA包含了细胞复制的信息
contains the information to keep replicating
如果细菌想要活下去 复制就需要停止
and if the bacteria wants to survive, that replication needs to stop
因而 免疫系统就需要摧毁病毒基因
and therefore its immune system needs to destroy the viral genel

请记住我的博客名 品生活
As it’s always my name of blogger this has been Life Noggin
别忘了要不断思考哦
Don’ forget to keep on thinking.
