Maybe you've never heard of "fat-tailed mouse lemur" of this size with the mouse almost at night in the woods jumping primates, but they are in the world than any kind of animal, and human relations have pro - Taken together, these guys can have a magical skill - hibernation (or borrow some researchers say: "dormant stage"), which occurs in the winter in Madagascar. Each year about half the time, fat-tailed mouse lemur were huddled, their metabolism slows down to their "fat tail" nutritional living.
MD, from the University of Pennsylvania's David Casarett explained that if one day need to go into this kind of human hibernation, the fat-tailed mouse lemur research hibernation mechanism will provide very useful information, after all, in addition to the huge difference in appearance on , and the human species share the 97% of DNA. Casarett said, "Maybe we can hope to create such a wonder drug, by a simple injection can reduce the person's metabolism 99%, so that he / she go into a state of suspended animation (suspended animation)".
So why would anyone want to enter suspended animation state? First, the hibernation feature is slowing metabolism, decreased heart rate, slow breathing as well as lower body temperature. A person may have more than one reason to enter a dormant state, but the most common is to delay death. Either been shot or had an accident or a heart attack, victims are faced with the same danger: Just a few minutes experienced a lack of oxygen to blood will be on vital organs such as the brain, resulting in serious injury.
More and more evidence suggests that conventional CPR (such as maintaining body temperature, heart rate recovery epinephrine, etc.) and sometimes more harm than good. High temperature and high heart rate, body organs will work overload, which causes blood oxygen and other nutrients can be consumed in a shorter time. When oxygen and nutrients shortage of a few minutes, will begin to cause brain damage.
So we should probably try to put aside adrenaline, so that the patient gets colder, metabolism slows down, so that the organ suffered irreparable damage will require less energy, is less oxygen to survive. Casarett said, "can be achieved by cooling the cells slow down the role of metabolism, so that some of the key cells consume less energy, except ....... can reduce the required amount of oxygen by reducing the rate of cell metabolism, [patients ] can make your body 'thought' yourself into a state of hibernation, "he said of the technology, if successful, would have to want to delay brain damage after 20-30 minutes - or even one hour.
"That would take more time for the patient or emergency personnel will be transferred to the patient to treat the condition better place, such as large hospitals."
In fact, some US emergency physicians and nurses have begun to use cold saline respiratory arrest patients to help sustain life, this is a more high-tech medical device called RhinoChill, which transport liquid coolant through the nose, so as to achieve cooling brain effect.
Meanwhile, the University of Pittsburgh Medical Center is also related experiments - experiments called "emergency and urgent conservation
Save "(" emergency preservation and resuscitation "), the blood of patients with respiratory arrest will be fully withdrawn by the cold saline instead of the body temperature drops to 50 degrees Fahrenheit (about 10 degrees Celsius) or so. This experiment in pigs has been success: an experiment, pigs were used in experiments by the laboratory personnel give a fatal injury, then all of the body's blood is cooled saline alternative, after the pig body temperature plunged dramatically by comparison with a control group to obtain a result. the temperature is lowered to pick up injured pigs after receiving medical treatment and higher survival rates.
Aside from the medical field, we have more reason to go into hibernation, such as long-distance space travel, travelers can extend the life of hibernation - at least guarantee that you will not hang up before it reaches the destination.
But the strange thing is, since it has been said of many attempts, hibernating species on Earth are also many, and why until now scientists have yet to solve the mystery of it? These lemurs in the body there is a gastrointestinal hormone, called ghrelin (Ghrelin), which is directly related to the lemurs who hunger and alertness, while the levels of this hormone during hibernation will be reduced to very low levels. " it's going down so lemurs hunger decreased alertness is reduced, perhaps they go into hibernation, and a relationship. " And when it comes to humans, the University of Texas Medical School researcher Cheng Chi Lee are working on something called adenosine monophosphate (adenosine monophosphate, abbreviated AMP) particles, it is ATP (adenosine triphosophate, called ATP), one of the constituent units, also is the direct source of all life activities required for in vivo tissue cells of energy, known as intracellular energy "molecular currency", Lee's research shows that adenosine monophosphate may induce basal metabolic rate decreased cause - in other words, It is to reduce the energy consumption rate of the cells. Casarett said that the role of adenosine monophosphate may be cross-species, or even the whole universe universal.
So what it's mechanism of action is it? AMP When a particle and a particle interactions ATP, ATP will fall off a phosphate molecule, and as energy storage "tank", which resulted in this case shedding phosphate can store less energy. In Casarett book, he mentioned, as rising oil prices when people own store more fuel, as when the body of AMP excessive cell will store energy.
Academic terms, this is called "the body cryotherapy" (Cryonics), its core is cooled to people "for decades or even centuries," and then they wake up in the future. Some local tyrant in order to prolong the life of your own, or ensure that when suffering from terminal illness can wait until effective treatment, are willing to spend a lot of money to his head or body freeze. In fact now it has been stored in liquid nitrogen in the body, waiting to be thawed in the future.
"But a lot cryonics risk," Casarett said, "No one has successfully thawed after being frozen case." This is also a great debate on ethics and psychology - woke up to find yourself in a whole new era, each of the same things are novel (see here that you have not thought of Arthur C. Clarke's "City of Stars "mean?), you wake up and have no family, no income, although the person is willing to be frozen in advance definitely think all these possibilities.
Although cryonics is very expensive, single cryonics organization Alcor clients not all local tyrant. According to Casarett said that some people use their life insurance to pay for this expensive "liquid nitrogen bath."
PS: About Alcor life mentioned above Extension Foundation, interested fans can hit trench egg ah ah ah I see their payment policies! Saying that my wife and children of foreigners in the future such a plan to do that ......
