桂阳县男科医院在那儿郴州医院精液检查With it#39;s stimulating effects,it#39;s easy to undersand.why coffee is the second most traded commodity on Earth after oil.For many,it keeps us awake and moving through our busy days.咖啡的刺激效果使我们容易理解,为何咖啡是仅次于油的世界第二大交易商品。它有助于保持清醒,帮我们挺过忙碌的日子。But how does it work?What exactly does coffee do to your brain?Whenever you#39;re awake,a chemical called adenosine slowly accumulates in your brain.And this adenosine binds to receptors which slow down brain activity-ultimately,the more adenosine there is,the more tired your brain feels.Which makes sense,as the longer you#39;re awake,the more fatigued you become.不过 它是怎么做到的?咖啡对大脑做了什么?当你清醒时,腺甘酸会在大脑内部逐渐积聚。腺甘酸会与减缓脑部活动的受体结合,最终,腺甘酸越多,你的大脑越累。这也有它的道理 清醒的时间越长 你也会越疲惫。Conversely,while you sleep,the concentration of adenosine declines,gradually promoting wakefulness.But it turns out that the caffeine in your coffee is incredibly similar to adenosine in structure.The caffeine works it#39;s way through your blookstream and into the brain.where it starts to compete and binds with adenosine receptors.相反,当你睡眠时,腺甘酸的浓度下降,逐渐使你清醒。不过,咖啡中的咖啡因在结构上和腺甘酸很相似。咖啡因随着血液流动,进入大脑,它在此参与竞争 与腺甘酸受体结合。But because it#39;s not adenosine,the;sleepiness; effect isn#39;t felt.Adenosine can no longer bind,meaning it#39;s calming properties are diminished.Which is great for you when you#39;re feeling tired!However,with long term use of caffeine,your brain responds by creating more adenosine receptors-which means more caffeine is required to elicit the same response.由于它本非腺甘酸,因此人不会有倦意。腺甘酸不再被结合,其镇定作用就会减弱。当你感觉疲惫时,这正合你意!但是 长期使用咖啡以后,你的大脑会因而产生更多的腺甘酸受体.It also means that when you try to quit drinking coffee or miss your daily intake.you might experience some with drawal symptoms and feel more tired than you would have before you ever drank coffee!But the caffeine doesn#39;t stop there!It also stimulates the production of adrenaline-you know,the Fight or Flight hormone?This increases your heart rate,gets your blood pumping and even opens up your airways.这也说明,当你想戒除咖啡或忘记喝时,就可能会经历某些断瘾症状,感觉比未开始喝咖啡前疲倦的多,不过,咖啡因的作用不止于此!它也会促进肾上腺素分泌,对,就是“或打或逃”的荷尔蒙?它可导致心跳加速,血流加快,甚至使导气管扩张。Furthermore,it affects Dopamine levels by preventing its reabsorption in the brain.which makes you feel happy!In fact this is the exact same thing that cocaine does,just to a lesser degree,it#39;s a drug,after all!This dopamine stimulation is also the aspect of coffee that makes it moderately addictive.此外,它也会通过阻止大脑重吸收多巴胺来影响其水平,使你更欢脱!其实 咖啡因也起着同样的作用,只是程度较轻。毕竟,它还是药物!多巴胺刺激也使咖啡具有一定的成瘾性。So can you drink too much coffee? It turns out there is a lethal dose of caffeine which is somewhere around 150mg of caffeine per kilogram of your body.This means if you weigh 70kg you would require 14,000mg of caffeine to overdose.Put into perspective an average cup of coffee contains roughly 150mg of caffeine.meaning if you are 70kg,approximately 70 cups of coffee would kill you.However,you#39;d have to drink those cups all at once. making it effectively impossible to overdose on caffeine from coffee.since you wouldn#39;t be able to physically fit that much in your stomach.那么,喝咖啡可能过量吗?其实,咖啡因存在致死剂量,大约为每千克体重150毫克咖啡因。也就是说 如果你体重70千克 则需要14克咖啡因才会过量。形象点说,平均每杯咖啡含量有150毫克咖啡因。若你的体重为70千克 喝下70杯咖啡会致死。但是,你得一次喝下这么多咖啡,单单喝咖啡导致咖啡因过量几乎不可能,因为你根本无法将这么多东西装进胃里。You#39;d also start experiencing mania and hallucinations before getting to this point.Caffeine also has a halflife of around 6 hours-so if you drank a standard coffee with around 150mg of caffeine,after about 6 hours there will only be 75mg left in your system and you#39;ll be feeling half of he effect.在过量前 你也会出现狂躁和幻觉。咖啡的半排出期约为6小时,所以若你喝下的咖啡含有150毫克咖啡因,约6小时后 你的体内只剩下75毫克咖啡因,你感受到的效果也会减半。And 6 hours after that,you#39;ll have 37.5mg-Leaving more room for adenosine to jump back into action.Which is why you may reach for another cup throughout the day to maintain that glorious,alert and energetic feeling.再过6小时 体内就仅有37.5毫克,使得腺甘酸有机可乘。这就是为何一天内,你一杯接着一杯地喝。才能保持光 警觉 精力十足。So drink up!And enjoy the buzz while it lasts:)那么喝杯咖啡吧!在作用尚存时好好享受 Article/201501/352459郴州哪个医院比较好 One of his slave girls has volunteered To be cremated with him,他的一个女奴隶自愿和他一起火葬So she can enter valhalla with her master.这样才能和她的主人一同进入瓦尔哈拉殿堂Lbn Fadlan, an Arab chronicler,伊本·法兰德 阿拉伯的年代史编者Writes the first surviving account of a Viking funeral.记录下了现留存最早的维京人葬礼They took the dead man and carried him onto the ship,他们将死者抬起 放在小船上Where they laid him on a quilt.;船上铺着被子A woman issued instructions.一个女人念悼词They called her the Angel of Death.他们称之为死神天使The slave girl was given an intoxicating drink.奴隶女孩被赐予毒酒The Angel of Death placed a rope around her neck.死神天使在她的脖子上套上绳索Then she took a broad-bladed dagger然后她拿着有宽刃的匕首And thrust it in and out between the girl#39;s ribs,反复刺进女孩的肋骨While two men throttled her until she died.与此同时 还有两个人拉紧绳子 直至她死亡 Article/201511/409825Perhaps their capabilities would only be limited也许他们的能力只会by how much power they could harness and control.受到所掌控能源多少的限制And that could be far more than we might first imagine.那有可能远远超出我们的预料For example, it might be possible to collect the energy from an entire star.比如,也不无可能从一整颗恒星上收集能量To do that, they could deploy millions of mirrors in space,为此,他们可以在太空中安置无数面镜子encircling the whole sun and feeding the power to one single collection point.环绕整座太阳,并将其能量汇集到一处Such power might make it possible如此惊人的能量也许能够to walk the very fabric of space改变时空结构and create a portal called a wormhole.并形成一个虫洞时空隧道This portal would act like a shortcut,这条通道会成为一条捷径allowing them to travel huge distances in the blink of an eye.让外星人能在瞬间穿越漫长的距离Like us, they would probably have evolved from像我们一样,他们也许也是从a species used to exploiting whatever it can.开采周围一切能源的物种进化而来So, if aliens ever visit us, I think如果外星人有朝一日前来拜访我们the outcome would be much as when我认为结局会非常类似Christopher Columbus first landed in America,克里斯多弗·哥伦布初次登陆美洲which didn#39;t turn out very well for the native americans.众所周知,那对美洲原住民是一次灾难So the journey that started with the search for water始于寻找外天外水源的外太空之旅has led us to far off worlds which I think could exist.我们已经进入了一个可能存在的遥远世界Worlds where the conditions and chemistry allow life to begin,那些世界的环境和化学条件可以育生命and then change into many different forms.并演变出丰富多的形态Even so, little green men are probably pretty rare.即便如此,外星人依然很罕见But in such a massive place as the cosmos,而在如此浩瀚的宇宙中we only have to look at ourselves for proof that我们只要看看自己就足以明extremely unlikely things can and do happen all the time.最不可能发生的事情随时都能发生Let#39;s just hope that if aliens do find us,让我们祈祷,如若外星人找到我们they#39;ll come in peace.他们是为和平共处而来 Article/201506/382788郴州治疗早泄那家医院比较好
