遵义市汇川区九龙医院没有的啊黑人遵义汇川九龙医院没有的坑不坑般About three years ago Eva Salem got into some trouble with a crocodile. It snapped her hand in its jaws. In a panic, she managed to knock out the crocodile and free herself. Then, she woke up."I imagine that's what it's like when you're on heroin. That's what my dreams were like—vivid, crazy and active," she says. Salem, a new mother, had been breast-feeding her daughter for five months before the croc-attack dream, living on four hours of sleep a night. If she did sleep a full night, her dreams boomeranged, becoming so vivid that she felt like she wasn't sleeping at all.Dreams are amazingly persistent. Miss a few from lack of sleep and the brain keeps score, forcing payback soon after eyelids close. "Nature's soft nurse," as Shakespeare called sleep, isn't so soft after all."When someone is sleep deprived we see greater sleep intensity, meaning greater brain activity during sleep; dreaming is definitely increased and likely more vivid," says neurologist Mark Mahowald of the University of Minnesota and director of the Minnesota Regional Sleep Disorders Center in Minneapolis.The phenomenon is called REM rebound. REM refers to "rapid eye movement," the darting of the eyes under closed lids. In this state we dream the most and our brain activity eerily resembles that of waking life. Yet, at the same time, our muscles go slack and we lie paralyzed—a toe might wiggle, but essentially we can't move, as if our brain is protecting our bodies from acting out the stories we dream.Sleep is divided into REM and four stages of non-REM; each has a distinct brain wave frequency. Stage one of non-REM is the nodding off period where one is between sleeping and waking; it's sometimes punctuated with a sensation of falling into a hole. In stage two the brain slows with only a few bursts of activity. Then the brain practically shuts off in stages three and four and shifts into slow-wave sleep, where heart and breathing rates drop dramatically.Only after 70 minutes of non-REM sleep do we experience our first period of REM, and it lasts only five minutes. A total non-REM–REM cycle is 90 minutes; this pattern repeats about five times over the course of a night. As the night progresses, however, non-REM stages shorten and the REM periods grow, giving us a 40-minute dreamscape just before waking.The only way scientists can study REM deprivation is by torturous sleep deprivation. "We follow the [electroencephalogram] tracing and then when we see [subjects] moving into REM, we wake them up," says psychologist Tore Nielsen, director of the Dream and Nightmare Lab at the Sacré-Coeur Hospital in Montreal. "As soon as you start to rob them of REM, the pressure for them to go back into REM starts to build." Sometimes Nielsen will have to wake them 40 times in one night because they go directly into REM as soon as they are asleep.Of course there is non-REM rebound as well, but the brain gives priority to the slow-wave sleep and then to REM, suggesting that the states are independent of each other.In a 2005 study published in Sleep, Nielsen showed that losing 30 minutes of REM one night can lead to a 35 percent REM increase the next night—subjects jumped from 74 minutes of REM to a rebound of 100 minutes.Nielsen also found that dream intensity increased with REM deprivation. Subjects who were only getting about 25 minutes of REM sleep rated the quality of their dreams between nine and eight on a nine-point scale (one being dull, nine being dynamite).Of course, REM deprivation, and the subsequent rebound, is common outside the lab. Alcohol and nicotine both repress REM. And blood pressure drugs as well as antidepressants are also well known REM suppressants. (Take away the dreams and, curiously, the depression lifts.) When patients stop the meds, and the vices, they're rewarded with a scary rebound.But the persistence of REM begs the question: Why is it so insistent? When rats are robbed of REM for four weeks they die (although the cause of death remains unknown). Amazingly, even though we spend about 27 years dreaming over the course of an average life, scientists still can't agree on why it's important.Psychiatrist Jerry Siegel, head of the Center for Sleep Research at the University of California, Los Angeles, recently proved that REM is nonexistent in some big-brained mammals, such as dolphins and whales. "Dying from lack of REM is totally bogus," Siegel says. "It's never been shown in any species other than a rat."Some theories suggest that REM helps regulate body temperature and neurotransmitter levels. And there is also evidence that dreaming helps us assimilate memories. Fetuses and babies spend 75 percent of their sleeping time in REM. Then again, platypuses experience more REM than any other animal and researchers wonder why, because, as Minnesota's Mahowald puts it, "Platypuses are stupid. What do they have to consolidate?"But, given that rats run through dream mazes that precisely match their lab mazes, others feel that there must be some purpose or meaningful information in dreams.John Antrobus, a retired professor of psychology and sleep research at the City College of New York says that dream content is tied to our anxieties. But he never found the extreme vividness in REM rebound that others assume is there, based on a higher level of brain activity which likely means more action-packed dreams."The brain is an interpretive organ, and when regions are less connected as they are in sleep, we get bizarre narratives," he says. "But its purpose? For that we have to ask what is the purpose of thought. We can't answer one without answering the other." /200809/48445遵义哪里可以看男科 A dog owner claimed that his pet, when given money, would go to the news stall to buy a paper. His friend insisted on a demonstration and handed the dog some money - The dog trotted off, but an hour later he had still not returned with the paper.  "How much did you give him?" asked the owner.  "Five dollars.  "Well, that explains it. When you give him five dollars, he goes to a movie."  一位养人宣称:要是给了爱犬钱,它便会到卖报亭买份报纸来。他的朋友坚持要来个演示,并给了一些钱。一溜小跑着去了。但一个小时过去了,仍不见它带报纸回来。  “你给了它多少钱?”的主人问。  “五元。”  “这就是了。你给它五元钱时,它就去看电影。” /201106/140324遵义市汇川区九龙医院不存在黑人给

Only Watson is worth pound;24million and is a global superstar. 身着夹克衫、牛仔裤、短靴的魔法少女艾玛·沃特森和其他第一天进入牛津大学学习的新生没啥两样。只不过,艾玛已经是身价高达2400万英镑的国际巨星了。 The 21-year-old beauty posted a picture of herself on her blog, grinning at the camera with her thumb up as she posed outside the iconic building. Watson also clutched an armful of books and revealed she will be 'busy studying' as she embarks on the new term. 21岁的艾玛在牛津大学的标志性建筑外自拍了一张照片上传到自己的客中。照片里,她竖起大拇指,对着镜头咧嘴笑,同时,手臂还夹着一摞书,暗示着在新学期里她要“忙于学习”了。 The Burberry model wrote: "To Everyone who is starting a New School Year, (sorry those who have been at school for a while Oxford starts late). Just to say have a great term and good luck with all your work. You might not hear from me for a while because I will be really busy studying but I wanted to just say hi and bye." 身为巴宝莉的代言人,艾玛写道,“致所有开始新学年的人(那些已经开学的同学,不好意思了,牛津开学得比较晚),我只想说祝大家在新学期里过得好,学习顺利。今后的一段时间,大家可能不会听说太多关于我的消息,因为我要开始发奋学习了。我想跟大家问声好,再道个别。” The young star put her education on hold at America's Brown University earlier this year to focus on her acting. She has since made My Week With Marilyn, due out later this year, and The Perks Of Being A Wallflower. But Emma has said she will return to Brown to complete her degree. She remains enrolled at Brown, even though she will study at Oxford this autumn, and intends to return to Providence, Rhode Island, next year to complete her studies at the Ivy League school. 今年早些时候,艾玛在美国布朗大学(美国常春藤盟校之一)休学,专注于她的演艺事业,出演了《和玛丽莲的一周》和《壁花少年》两部电影。但是,艾玛说她会回到布朗大学去完成她的学业的。尽管今年秋天起,她会在牛津大学读书,她仍然是布朗大学的学生,明年她就会回到位于美国罗德岛州普罗维登斯的布朗大学去完成学业。 /201110/158168遵义市汇川区九龙医院治疗前列腺炎没有黑哉 遵义中医院不孕不育科

Rossdale is married to singer and fashion designer Gwen Stefani, and the couple has another son named Zuma.   加文·罗斯代尔和儿子金斯顿在洛杉矶。罗斯代尔的妻子是歌手兼时装设计师格温·史蒂芬尼,这对夫妇的另一个儿子叫祖马。 /200910/87652 Keep Your Cat Indoors 猫咪屋里待着好  Kitties allowed to wander outdoors unsupervised are at much greater risk than house-cats, no matter the time of year. But a cat left outside in cold weather can literally freeze to death, or become permanently lost.  无论什么时候,如果猫咪无人看管,待在室外要比在室内危险得多。寒冬腊月的时候,猫咪待在室外很有可能会被冻死,或者走丢,再也找不回来了。  Keep Them On A Leash 链不可少  Keep your dog on his leash when you're outside with him. It's very easy for pups to lose their scent and get lost when snow or ice is on the ground. Light-colored dogs with snow on their fur can quickly blend into the background, making them nearly impossible to spot.  出去遛的时候,链一定要戴好。冬天下雪或者地面结冰的时候,的嗅觉很容易受影响从而迷路。在漫天白雪中,如果毛色浅的身上积了雪花,那么人们是很难把它们从茫茫白雪中辨认出来的。  Keep Them Warm 保暖很重要  Don't shave or clip your dog's coat too short during the winter months. A longer coat will keep him warmer. If your pup has short hair, a doggy sweater might be in order.  冬天的时候就不要把毛修剪得太短了,长长的毛才能保暖。如果你的小的毛不够长,那就给它穿上件外套吧。   Being Active During Winter 冬天也要做运动  If you and your dog participate in lots of outdoor winter activities, make sure his species-appropriate diet has sufficient calories and protein to meet his energy requirements. This may mean increasing his meal portions during the winter months.  如果冬天还是做很多的户外运动,那么别忘了给它加餐,要增加热量和蛋白质的摄入以保能量的供应。  Give Them A Warm Place To Sleep 温暖小窝睡得香  Make sure your pet has cozy, draft-free winter sleeping quarters. If your dog has her own crate, make sure her winter bed inside it is one that will keep her warm. Your kitty should have a snug sleeping spot as well, with warm bedding she can curl up in.  给你的宠物一个温暖又自由的小窝。如果你的小有自己的屋,那么要确保它的床铺够暖和。猫咪也一样,床铺要温暖又舒适,这样它们才可以自如地蜷缩在里面。  Give Them Extra Love 寒冬也要爱满溢  Give your frail or older pet some extra love. Cold winter temperatures can be especially hard on a senior pet, or on a dog or kitty with chronic, debilitating conditions.  给那些虚弱的、上了年纪的宠物更多的关爱。冬天对于那些年老的、有慢性疾病的、健康状况不佳的宠物来说需要更多的照顾和关爱。 /201110/156550遵义早泄治疗哪里最好遵义治疗前列腺肥大的费用
