Sea pigeon egg collection is difficult to ensure that those agricultural crops, and food shortage, so sea pigeon egg becomes a Saxon (Saxon) farmer diet is an important source of protein. However the sea nest up pigeons in the cliff rock Ridge, collecting sea pigeon egg to risk their lives to climb a few hundred feet high cliffs, as it is jagged rocks and bellowing roar of the sea. In addition to these risks, the anger of seabirds may also attempt to steal them on these precious people immature eggs.

Gunong in Anglo-Saxon (Anglo-Saxon) era, the gunong (or farmer) is located at the bottom of society. His job is to cultivate a small piece of land, the land produced food to keep the family livelihood. Land farming rely primarily on cattle and wooden plow, quite hard toil. In addition to tillage, the gunong must also be yourself, fence plaster on the cover of the shack to blot out the wind and rain.

Their slender Hazel tree, effortlessly weaves fence, then the plaster coating on the above, to block the wail of a North wind. This work also dirty and smelly because plaster is water, mud and straw and livestock manure mixture!

Marsh's acquisition of iron ore were Saxons requires a large amount of iron to make tools and weapons. Bog iron acquisition ' name is reflected in their work, look for iron ore swamp. No matter what season, he had in the wet Marsh in the effort to find, to 40 kg per day of ore to the smelters.

Examples of work in this kind of work, not only offering Board and lodging. If he dares to steal-of silver coins, which would be very cruel punishment. Theft of wether yinxie be criminal punishment, if the coin is lost, the hand of the crime will be cut off, nail factory doors!

Monk in Saxon times, the monks lived in the monastery. They must, like the gunong fence plaster, cultivated land to build a cabin to feed themselves. In addition to daily wear surface (literally, is the daily grind grain into flour for baking into bread), they have to do eight times a day, including one in the middle of the night.　　Monk also cold airless room, fly head carefully copied manuscripts as normal, which often makes their body and eyes ache hard. Virgin (Viking) of the pirates looting and pillaging to be implemented, Viking pirates must leave their homes in the United Kingdom by emulating! this means to keep the boat through the storm raged for a long voyage of the sea. Pirate ship, space, and no toilet slush, unbearable.

Viking pirates don't like walking along the headland of bypass, they will usually install at the bottom, the wooden wheel towing their barge across the Cape. In order to make the boat easily towed, need to chute coloured oil, the most common greases are taken from the pressing of fresh fish. But don't forget, caught fish before they are put on a few days, is definitely a bad smell unpleasant.

Tea has the hypoglycemic effect

Technology channels () message: Japan scientists recently confirmed by animal experiments to loquat leaf as raw materials made of loquat tea with blood glucose and blood pressure by inhibiting effect. 　　　　Japan Kagoshima University and other researchers of the distilled water boiling bubbles, loquat tea concentrate it dry after the extraction of active ingredients, then mixed with the composition of the feed and ordinary feed fed separately has diabetes and hypertension in rats. Experimental results show that consumption of loquat tea components feed the average blood glucose value of diabetic rats than similar edible General feed for about 19% lower, while suffering from hypertension in rats 7 weeks in a row with a loquat tea consumption of feed ingredients, blood pressure decreased on average by about 20 mm of mercury. 　　　　In addition, the uptake of loquat tea composition of experimental rat kidney surrounding visceral fat reduction, neutral fat in the body also reduces to about 54 per cent. Participation in the study of Kagoshima University Professor of food function, through the letter Fujii study, loquat tea have a variety of functions to confirm that future researchers will be an in-depth analysis of the composition of loquat tea, to study its effect on the human body.

Bitten by a dog, a year after an incubation period of rabies from up to several decades

20-year-old young man Henan pan, this two-day high heat, sweat, headache, fear of water, wind, small hands stack will cause his throat muscles spasm, Oh. The expert consultation, this once being misdiagnosed as suffering from "encephalitis" or "tetanus" youth, a year ago had been a "healthy" dog bites, finally was diagnosed for rabies.

Ditan Hospital infections Department Director Zhaohong heart said, is not necessarily a rabid mad dog bites or "dogs" (no clinical signs of poison the dog and the rendering of clinical symptoms before the outward detoxification of dogs), with the cat and rat virus, animal bites, latency can be a few days, or years, even decades. Once bitten by an animal must be wound cleaning, injection of rabies vaccine.

The human sense of smell "three-dimensional" comparable Hound

When the old man's nose began to uplift and be able to walk upright, the human sense of smell has been reduced to a second level, only those dogs also have smell this skill. 　　But a new study finds that humanity buried smell tracking keeps hounds were all envy. UC Berkeley to do a study. Found that the majority of the students to blindfolded and wearing headset track 30 feet out the smell of chocolate; they may even be in this kind of invisible roads change direction after accurate change direction tracking to smell. Even more strange is that students participating in the experiment with a three-dimensional sense of smell: when researchers individually blocked these students of a nose, they smell tracking accuracy is greatly reduced.

From nose to smell location in pointing, scientists hope this worked out to hazardous electronic nose detective work, such as the use of the invention for mine detection, etc. They study published yesterday in the journal Nature Neuroscience "network version, United States Army Research Office on this study provides partial funding.

Some experts believe that this discovery could help refute the smell in the olfactory trace misconceptions.

United States Northwest of a Neurology Professor Jay-Goth Fred said: "this study shows that human sense of smell than most people think. Our life is indeed from our Visual and auditory dominate, but if you can pay more attention to your sense of smell, it will be your life in a more focused areas. ”

Russia study says rock destruction of brain stimulating a suicide

As far as Russia media reported on 22 June, the latest research shows that the rock and roll to the human ear cannot hear of treble and bass to destroy the human brain that increase suicide tendencies.

People long ago noted music medical role. In the 3rd century BC by ancient times used patiya established a music therapy centre. Where doctors with specially selected music for those frustrated and neural disorders and heart disease patients. The music produced by electromagnetic waves can make every cell of resonance, it is well known and common sense. While music can affect blood pressure and heart rate, but you can also change the frequency of a person to breathe.

Unpleasant concert attracted awful, stomach cramps, and even the loss of a keen vision and taste. Some special music to profound impact on some people, even to let their coma or paralysis. Other music can cause the feeling of pain. Even the dog is also very sensitive to music. For example, heard some music, United Kingdom Terrier blood pressure also increases as the changes.

African Shaman Drum will enable people to have a kind of illusion. This drum directly on a person's brain's internal structure. In the neck area, received responses on the drums here can cause changes in air pressure.

In Japan to 120 in breastfeeding women made the investigation. Some women to listen to classical music, listen to jazz and pop. The first group of mothers milk production increased by 20% while those listening to modern music of women is halved. Pop music through the human ear cannot hear of treble and bass directly on a person's brain, essentially all the organs of the human body is capable of directly hear these sounds. Some psychologists said that rock music was able to increase the tendency of people to commit suicide.

Color contact lenses may cause permanent eye injury

(); According to the Washington-United States food and Drug Administration warned 27 said that wearing decorative contact lenses before the professional eye doctor for advice if the unauthorized use, serious eye damage may occur.

Decorative contact lenses is known as "beauty glasses", however, abuse of decorative contact lenses that can cause permanent eye damage, even blindness. United States Drug Authority said that improper wearing decorative contact lenses can also cause all sorts of eye problems, such as conjunctivitis, keratitis, corneal abrasion, etc. In addition, some people in order to transform lens colors also often worn with somebody, it's easier to throw an eye infection, allergies and other symptoms.

Water delivery in surviving dispute and mother shall close conditions

From October 14 to 31, Guangzhou five babies have to water delivery approach to the world. In this way in Shanghai, Hangzhou, Nanjing, etc have been there for some time, but this was the first in Guangzhou. According to the twelfth people's Hospital, Guangzhou, as the doctor in childbirth pain can contribute to the fear of natural childbirth pregnant women how to have a child, the attractiveness of the pregnant woman, currently has more than 20 pregnant women to the hospital registration requirements for water delivery.

Then, the water delivery what strange?

Lights, music, creating a comfortable atmosphere in the delivery room

To keep the room sterile State, journalists must wear hats, masks, robe, and put on the maternity ward shoes before they enter the water delivery the delivery room. In the delivery room, journalists see, this is a large room of 40 m2. From Denmark imports of white labor bathtub in the room, appearance and massage bathtub. In addition, there is a rest bed, a bed, a baby box.

Guangzhou City people's Hospital of obstetrics and Gynecology and Director of the 12 Muir Stephen Lesley pointed out to the journalists by childbirth cylinder unique: delivery cylinder side there is a button that can lift cylinder, bath and bed, high for women after childbirth in the water tank from confinement to bed processing matters such as the placenta; childbirth without handrails on both sides of the tank to ensure that the bacteria have no place to hide; childbirth is the constant temperature of the water tank, the water temperature is kept at 37 ° c, make expectant pregnant women feel warm and comfortable; outside of the water after it is processed into delivery cylinder, complete aseptic, can directly drinking; tank is more rugged, pregnant women can use them to adopt a different position in labor, such as kneeling, squatting or lying.

In addition, delivery room decoration is extremely unique. In order to create a warm atmosphere, technicians specialized in childbirth bathtub at the top of the ceiling-mounted with colored lights and soft music playing in order to relieve the tension of the mother. • Installation of advanced video equipment to leave precious information.

Women felt that it was not so painful

To date, a total of 5 maternal "enjoy" live water delivery, reporters interviewed first and second maternity.

In all, became the first water birth, in the 28-year-old Arab-ping is "Serendipity results." Delivery cylinder 13 October just installed, ping 14 October morning because of the emergence of uterine contraction came to the city people's Hospital of XII.

Follow the ' ping the original idea was to do a caesarean section, but in Muir of Director's recommendation to adopt the final delivery in water. 3: 30 p.m., the ping of the mother company of entering water delivery, delivery in less than an hour, a child born to smoothly. She admits that the production time is, of course, be pain, also very hard, but there should be no ordinary childbirth pain was back then.

30-year-old Fu wave is the twelfth people's Hospital, Guangzhou, "look" of the first water delivery in pregnant women, but because the son was in the "Rai" mother belly refused to come out, I missed the first opportunity. Fu wave 19 October gave birth to a large heavy weight 8.1 bulge, the production process used for two hours.

"The doctor said that kids are so great, the degree of difficulty quite large. Thanks to water in childbirth, if using ordinary childbirth on the pain! "cheerful she happily recalls. Most let her feel that water delivery worth is postpartum recovery quickly, her perineum is only slightly torn, now completely restored, and others with her birth year is still affected by inflammation, redness of the perineum. Now, Fu wave became the water delivery obligations "promoter", the hit is going to have children friends recommend.

Water delivery can reduce the trauma

According to Samuel Shih-Director, water delivery is different from ordinary labor and cesarean delivery, it not only helps to relieve the pain, but can reduce the trauma, speeding up recovery. If you have a family, accompanied by her husband, can better strengthen family ties. This is the water birth registration, many of the main reasons.

As the first company to introduce water delivery project hospital, Shanghai changning hospital so far has done more than 1000. The hospital's doctors told reporters Chris pan, water delivery advantage is obvious.

In General, soaked in warm water, body and mind are relatively calm; this for promoting maternal Cervical Dilatation, mobilization of maternal body's natural rhythms. In addition, water buoyancy can muscle relaxation, to put more efforts for uterine contraction, acceleration of labor. In addition, the pregnant women in the water activities more than in the bed, easy to take along a different posture help pelvic relaxation, pelvic floor muscles, promote the expansion of the cervix, for easier through the birth canal fetus.

For newborns, the State of the water and the womb in amniotic fluid, feeling very similar, can form a feeling of transition, to let children have a buffer.

Select water delivery conditions

Although the water in the delivery of the benefits are many, but not every pregnant women are suitable. Miao Director said, should be at least the following requirements:

1. prior to screening, infectious diseases must be completely ruled out. "Because delivery cylinder is not using high temperature sterilization, so we cannot take the risk. ”

2. fetal medium size, in theory, generally not more than 7 pounds. But in reality, the baby's weight and there is no strict restrictions, such as Guangzhou five water births baby, from 5.9 catty to 8.1 pounds.

3. maternal pelvic to large enough, the best in the 30-year-old age. But in the twelfth people's Hospital, Guangzhou, and has successfully conducted in pregnant women giving birth in water with a maximum age for the 33-year-old.

4. suffering from diseases, maternal, such as heart disease in women is not able to give birth in water.

5. If the prior examination found no health or fetus sanyinjiao wouldn't be able to give birth in water.

In the delivery process, but also some attention to place:

1. in order to

Glycerine help maternity defecation, and encourages women every hour or two on a toilet.

2. be open to the Palais gate 3-5 cm into the water again. If an infection, fetal heartbeat, unusual phenomena such as maternity leave bathtub, required to produce the bed up processing.

United States labor disputes in the Shui (related link)

Since the late 1980s, United States, the first "water birth" centers was established, it is estimated that the United States about thousands of babies born in the water. There are conditions for the "water delivery" of hospital development from 10 to about 150. However, the United States Federal Government health and humanitarian service "Department made it clear that the current" water delivery "benefits of the research is still very limited. So in the country are called "water delivery" in the United States can only be regarded as a new thing.

As with any new things appear raises different sounds, since the "water delivery" in the United States since its introduction, the expert and people have always had a different view.

United States Association of Obstetricians and Gynecologists that "water delivery" has great technical barriers, and doctors had to go in the water delivery, implementation, not only high difficulty, easily out of the accident, the infant is also easy to inhaling capacity tub of water, causing suffocation and infection, a significant increase in the neonatal mortality rate. Therefore, they do not recommend doctors use this method to maternal birth.

And non-profit institutions "water delivery international" were of the view that women in the water production can help speed up the physical and mental relaxation, and to labor, physical injury is relatively small, there is a distinct advantage.

Therefore, at present, the United States, the official more maternal first ask your doctor or midwife advice about their suitability for the "water delivery" and then make a decision.

Some ingredients in fruits and vegetables can kill cancer cells in the blood

[] Message: United States scientists recently published study report shows that fruits, vegetables and red wine contains an antioxidant ingredients can kill Leukemia patients with blood cancer, not to hurt and healthy cells.

United States of Pennsylvania University of Pittsburgh School of medicine experts in United States "biochemical journal, reported that a lot of fruit, vegetables and red wine in a place called anthocyanins of antioxidants. Researchers from black raspberry extract anthocyanins, and analyze these anthocyanin-3-Rutoside glycosides (C-3-R) matching mechanism, the role of the blood cells.

The study found that low doses of C-3-R in 18 hours to an experimental samples of half blood cancer cells killed. If you use high doses of C-3-R, 18 hours to the samples of blood cells in all killed. In several experiments, C-3-R on different types of leukemia and blood cancer cells can produce similar effects. Researchers say experimental proof C-3-R enables cells to produce a peroxide, causing blood cancer cell death, but the peroxide on normal cells is not toxic.

Used for the treatment of leukemia chemotherapy and radiotherapy will kill leukemia, damage healthy cells and tissues, and have other side effects. Therefore, many experts are dedicated to research new ways of treating leukemia. Currently, the United States specialist is assessing the possibility of discovery to the clinic.

Know who makes the heart grow on the left?

Popular words: strongest Idol Mermaid most cattle series avian flu symptoms

From the appearance, the people in general are symmetrical, obviously, this kind of symmetry should be aesthetic appearance of a necessary condition, however, this kind of symmetry, didn't do it inside and out, because people offal is not symmetrical. Such as heart, liver, and other distribution in the body of one side, while at the same time distribution in lung though, but still left on both sides of asymmetric, only the kidney, ovarian, and so few organs in General is the symmetrical distribution. This asymmetry is what?

If you are considering starting from fertilized eggs during development, then the issue becomes all the more strange. Because the Zygote itself is a completely symmetrical spherical body and then it symmetrically divided into two successive divisions to form a spherical cell aggregates. So when the embryo in its appearance remain symmetrical, its internal began to appear around the asymmetry of? the asymmetry of the mechanism also?

To get the answer to this question, the only step by step back embryonic development from a single fertilized eggs, to the emergence of asymmetric shape. As in the original Zygote Division stage, keep progeny cells are consistent, that is, the child cells either form, structure, or components, in particular contain the proteins are the same. We know that life's basic feature widget is protein, if there is a difference between the two cells, then contain the protein must have type differences. While a cell which contains protein, simply by its corresponding gene contains DNA sequence information is cell protein processing reading internal, and then translated into a protein's amino acid sequence information, which ultimately makes gene expression and production. So the difference between proteins must be derived from the differences in gene expression, that is, if two offspring cells, they are the expression of genes, will lead to its protein factories production of proteins, thus determining their structural and functional differences emerged.

Obviously, for a start up global symmetry of embryos, sure there exists a crucial developmental steps so that the descendants of the fetal left cell, gene expression differences, thereby further makes the whole embryo occurs around of morphological and structural asymmetry. Therefore, to study the problem in a way, is from early embryos is still at the beginning of the period left-symmetric, monitoring of left and right sides of cells used to assemble the protein mRNA sequence and the corresponding protein products, and see when the variance, then allows find causes this difference is what is the source of the gene.

Now researchers have found that some genes, they are only one side of the early embryo was valid expression, and then they are encoded proteins can act as a key signaling molecule that induced the edge of the embryonic growth out of its symmetric position different morphological structure. Researchers in the chicken embryo development process, discovered the first asymmetric shh expression of genes, encoding a protein expression is a very important signal protein molecules. Subsequently, also in chicken embryos inside found another seven genes that are involved in the chicken embryo development of non-symmetric. Progress is more important, the eight genes and their encoded proteins are closely related, we can say that their role is part of the buckle. And chicken embryo development of asymmetric is composed of a series of genes and their encoded proteins interact and control results.

Researchers through human intervention these genes to start the program, you can effectively change the location of the cardiac growth or direction.

In addition, there are other more genes are involved in the development of non-symmetric.

In addition to chicken, in other vertebrate body is a similar asymmetry growth control mechanism? now researchers in mice and amphibians of embryonic development, have found a similar mechanism of asymmetric developmental regulation. Therefore, we should be able to estimate, such a mechanism must also exist in humans.

However, even if we have been able to go back to the genes that are still only partially answered the question. If Inquisitor ask so, earliest gene expression of non-symmetric and who commands under? we hardly know what is what determines the heart have to grow on the left.

Man-made "natural selection" Asian elephant tusks "not"

Toothless gene in the spread of Asian elephants in the

When ivory into death flag, Asian elephants have transformed — — —

As long as the sword Trident is male Asian of ivory as a symbol of the strong, but now, Asian elephant population, hung as fewer and fewer, more surprisingly, few hung like, actually appeared more and more toothless male elephant. This is the natural evolution of results, or select Asian elephants helpless?

Ivory became the symbol of Asian elephants killed, toothless, as more and more.

Ivory has been viewed male elephant symbol of strength, the two long, curved incisor teeth, in addition to being hung like as fighting weapons, they get a female elephant favor capital. But for Asian elephants, has a huge ivory will no longer be a bragging, but become a sign of death.

Asian elephant family only male have ivory, ivory trafficking of enormous profits also let greed of poaching are evil gun a male elephant. Human records of ivory weigh as much as 97 kg, but due to poaching we now difficult to find weight of more than 45 kg of ivory.

In the country, the most rampant poaching Asian elephants in the 1980s to the mid-1990s, in one of two large-scale poaching, a total of nearly 30 head Asian elephants killed. In 1990, promulgated by the international ivory ban was once so rampant ivory smuggling has eased, but the elephant from tooth of crime has not yet been eradicated.

"At present, China's population of Asian elephants only about 250 head, of which there are about 200 head in Yunnan Xishuangbanna. "Zhang, Ph.d., told reporters. Zhang, Dr., Associate Professor of Beijing Normal University, the International Fund for animal welfare, on behalf of the Asian elephant project in China. Since 1999, Zhang began with a post graduate in Yunnan wild Chase in the footsteps of the Asian elephant.

In addition to the male elephant numbers decimated, even more surprising is the fact that elephants in ivory-like more and more. Zhang, Dr. said: "in India a nature reserve, not long ivory-like 20% can be achieved. We at Yunnan Xishuangbanna also found no tooth-like. ”

What causes male Asian elephant transformed? is this is the result of population natural evolution?

Toothless, as more and more, is the choice of Asian elephants helpless.

"In fact, toothless gene in Asia as the body is always exist. Dr. explained: "Zhang" nature has 2% to 5% of the male Asian like born not of ivory. But now the Asian elephant population in toothless hung like a proportion substantially exceeds the normal range, toothless gene in the male elephant populations spread, it's against the law of nature. ”

Hung like long ivory is a normal result of natural selection. Ivory is hung like to fight, a powerful tool for spouse, is hung like a strong symbol. The larger the male elephant ivory in contention for the spouse of the fighting during the more able to easily win, gain and female elephant mating rights. If in full accordance with the laws of natural evolution, the male elephant ivory and ivory, the larger male elephant will own gene reserves the likelihood of genetic indefinitely, no ivory-like will be eliminated.

But now the situation on the contrary, due to poaching, the male elephant ivory and ivory, the larger male elephant more vulnerable to hunt, toothless male elephant is preserved. This toothless gene has been preserved, there is a gradual loss of tooth gene. This is not a natural evolution, but Asian elephants in the face of poaching ' muzzle made of choice.

Hung like decimated, inbreeding increases, more and more vulnerable populations of Asian elephants.

Poaching of males like killing, not only for Asian elephants of ivory disappear, even more serious consequence is the Asian elephant promoted genocide. The male elephant ivory, generally within 12 to 14 years old when the President, and this time also happens to be hung like a sexual maturity period, but they haven't had a chance to be mated, murdered and poaching ' bloody killing.

"At present, the Chinese discovered in the wild can make individual identification of adult male elephant has less than 20 head. "Zhang, Ph.d., told reporters. And because the number of adult male elephant, many male elephant ivory have not fully grown it has been hunted. Asian elephant sex ratio imbalance, it is for the Asian elephant species is very dangerous.

In India a South Asian elephants nature reserve, with 400 head female elephant, but only 4 head hung like participation in propagation, as a result, the population of offspring is this 4 head hung like offspring. China Yunnan nangunhe region a 20 long Asian elephant population, only two male elephant. Due to long-term inbreeding, Asian elephants genetic diversity continuously forfeit, very easily lead to a large number of extremely fragile, even do not have the ability to reproduce. This makes Asian elephant populations are becoming increasingly vulnerable.

A richness of species gene implies life to adapt the environment changes. Even if the environment changes dramatically, some genes may play a role and sustain life. Such as insects, faced with the variety in nature and does not exist in the artificial insecticides, always a few insects survive and subsequently reproduce themselves produce resistance to future generations. Therefore, genetic diversity can be said to be species survival in the face of nature changes or not.

Lack of genetic diversity of species, and environmental changes or specific diseases are particularly vulnerable, slightly accident could result in the death of massive population. While initially was selected strong male animal genes, in propagation of several generations later, often lose their superiority, to improve the quality of future generations.

Habitat into ecological Islands, Asian elephants facing natural threat of extinction.

In addition to the Asian elephant poaching, devastating disasters were caused by species of human activity. "We see in the wild, farmland, cultivated land, rubber plantations, etc., the Asian elephant Habitat become fragmented, Asian elephants living in one of this

Samples of ecological island. "Zhang, Ph.d., told reporters.

Asian elephants are usually groups activities by female like steer a baby elephant. Asian elephants in food intake, daily to eat about 300 kg of fresh fodder, elephants lot… for food sources. In order to survive, elephants run daily to 18 to 20 hours. Hung like General grow to 10 years old to 14 years of maturity, they will leave the elephants, and began to walk alone. Estrous season coming, elephants will catch up with the female elephants mating, complete, and then left again.

But now, Asian elephant habitats being artificially isolates, dams, rice fields, rubber plantations, etc. become elephants impassable artificial barriers. Walk out-like the quarantined in population, could not find the female elephants, a female elephant nor and male mating breed, like an elephant in no baby elephant was born.

Zhang, Ph.d., they found the field observation, Simao region a population of Asian elephants, from 1996 to the present, nearly ten years had no male elephant population involved in reproduction, like the female old, day by day without a baby elephant was born, this population might naturally perished.

Background knowledge

About the Asian elephant

Asian terrestrial mammals like the Asian continent in the biggest of all is dark grey or brown skin disperses lives with hair. Adult male Asian elephant shoulder high about 2.4 m to 3.1 meters, weighing about 2700 kg to 5000 kg. A little like the female figure.

Our history has been a very Asian elephants resource-rich countries, half of the country have a trace of the Asian elephant. In 3000-3500 years ago, Asian elephant distribution of North Limited is located in Yellow River North of Hebei yangyuan area, and the short title of "Henan Henan" Word is a staff led by the Asian elephant.

There was also a tayu ploughing with Asian elephants, legend has it that for livestock rearing is used as a riding, farming, handling and as a tool of war. Oracle also has a number of Asian elephants in the record, such as the "Palace in the rain, an elephant," "to like John Yoo (Woo) b", etc. Shang dynasty Henan area climate was warmer, suitable for the survival of the Asian elephant, unearthing in Anyang has unearthed a large number of ivory and ivory ornaments. Future climate change, gradually migrates South Asian elephants. In the Tang dynasty, it is also widely distributed in Guangdong, Guangxi, Fujian, Jiangsu, Zhejiang, etc. along the Yangtze River basin. But since then, under the pressure of the people, Asian elephants in the distribution area began to narrow gradually moved south. South Asian as extinct in the 12-13th century, Lingnan and Guangxi in Asia as extinct in the 17th century.

Now the distribution to our Asian elephants in Xishuangbanna Yunnan lincang and Simao, and parts of South Asia, Southeast Asia. Asia seems to be included in the international CITES endangered species of animals and wild animals in our country level, the country is now the only remaining more than 250.

Brain exercises not complicated simple habits can enhance intelligence

IQ is not completely original decided to congenital! want to make ourselves more clever? so please exercise, phone number, and change their eating habits, because this practice can make their own intelligence in a week promoted by 40%.

According to the United Kingdom the Observer newspaper reported yesterday, the United Kingdom broadcasters will broadcast the week be clever "take the lead on simulation test, and depending on the experiment concluded effective" brain gymnastics ". In fact, the "brain exercises" and not complex, are a few simple habits, such as closing the eyes shower, see countdown, diet, health, exercise, sleep and back form and play the "digital" games. In addition, the study found that change daily mode, you can significantly improve IQ.

At the same time, the study also found 15 test. These acceptance tests were developed according to the scientists of the week be clever Guide recommends daily adhere to exercise the brain. Experiment, tested to follow guidelines for improving the intelligence of the practice, including the numbers game, at home with his eyes away and not commonly used in the other hand operating mouse, follow directions schedule schedule. After a week later, of the IQ test for at least 10% of the approximately increase, up to 40%.

The study finally said: "more and more proof that by increasing the memory, increase the sense of space, to do things against normal and reasonable arrangements for catering can improve brain function, so that people become more intelligent. ”

Experts say that like to eat what fruit is related to sexual orientation (map)

Hi eat strawberries publicity and charm of women out of the ordinary (source: Russia news network)

Russia news 22 February news, Sexology scientists recently passed one study concluded that women like to eat what kind of fruit with their sexual orientation, according to people's daily on a fruit preferences can tell a person's personality.

For example, if a woman like apples, which means that the women lack of romanticism.　　Typically, like Apple's seeds and, like Apple's female character strength, but realistic and reliable. Strawberry is different, it looks gorgeous and soft. Like eating Strawberry woman ever will not forget the real to demonstrate her beauty, charm and seduction women usually have both.

Orange closed and focus on content. Like to eat an orange women always modest and shy and mysterious make men in homage. Like to eat an orange women also belongs to the creative crowd class, they are smart but not funny.

Like to eat grapes of female fear-arc sin, the pursuit of happiness is the eternal goal.

Like women with PEAR is difficult to resist temptation, also there are crowds of around pursuers. They are so charming, because when you take her hand on her in the future even more care.

Researchers also said that male friends like what kind of fruit and their sexual orientation and women are slightly different.

Men and oranges is the perfect combination. We advise the female friends, like eating oranges of men will give you many happy and satisfied, at any time without doubt that men will be on you. In addition, likes to eat pineapple's men will always bring you exotic feel. It is noteworthy that this extensive exotic feel including communication, lack of sincerity and calm. Also, like eating peaches of men will always be chosen for its Valentine, even the few by humiliation and despair will not give up. They will try and various women love experience.

Experts say: first-child identification shall have no legal effect

According to Guangzhou daily reported that recently, called a "China's paternity network" Web site directly to the paternity of the business to the Internet, as long as the hand and foot, claiming that their samples mailing, eight days after the results will be at home, etc., on this, the expert said that paternity has been open for community, local many hospitals have the business, select online paternity, and the identification of the conclusions made by the Agency and shall have no legal effect.

Each of these services charge, hyper-accurate detection 1900 Yuan per person

To personally identification, the Internet can be a reporter recently interviewed understand? to a family known as China's first "paternity testing network".

Journalists after landing the website page that the Web site claims that their parentage, here the wife can maintain their own dignity, regain harmony family.

This reporter has learned that the Web site fee is very low.

In accordance with its tariff, accurate detection (99.99% accuracy) per person $ 900, high-precision detection (99.999% accuracy) per person $ 1200, hyper-accurate detection (99.9999% accuracy) is as high as $ 1900 per person. Mailing samples after eight days may generate results, if you select "lightning detection", three days ahead of the results generated will charge $ 300 per person, if the five days in advance, the fee to $ 1000. Instead the reporter noted, almost every service cannot be separated from charges, costs more frequently then the wave.

Blood, hair samples, ice cold storage is a mailing identification of amniotic fluid

This reporter has learned that the paternity test network to Nanjing, called a "set up along the back, you need to" biological paternity identification but does not need to directly go to the site in Nanjing, follow their tips can gathering samples such as blood, hair, mailed directly to the website tips contact address on it, the most amazing is the Web site that also can extract 6 ml of amniotic fluid or spend money to make them a partner to help extract, also remind "summer's ice cold storage" evacuation over, you can identify the fetus is not natural.

Press start to a customer's identity linked to the company a leader, someone said that as long as you follow the tips of their operation, you can feel at ease, results, and they are many outsiders have such a paternity test, the customer already proliferated Shanghai, Jiangsu, Zhejiang, Beijing, Guangdong, Tibet, Xinjiang and other places, the reporter said that he did not have to worry about the scene some test results, other then that, absolutely no problem, where do paternity is in the scene.

But when a reporter on the identity, the principal immediately indicates that the inconvenience to interview and said that the CCTV reported they were the day before yesterday, has against them so low point.

Expert analysis: identification of results have no legal effect

Journalists after leaving the site in accordance with the commercial register, query the Nanjing Bureau, but the phone staff indicated that many people have asked, does the company, but the scope is not a "paternity".

For such a paternity test to the end and not legitimate, the results can be unreliable, reporters interviewed second people's Hospital, Guangzhou, forensic evidence forensic Director Sun Xiaoping put, he told reporters, currently for paternity has been let go, as long as you have a certain technical conditions on it, but if you want to have legal effects, eligibility and approval of the judiciary. She told reporters that generally have the approval for the justice sector institutions of identification, from the samples to the final result, and have a very strict procedure, "because we do these identification will be liable if the identification is wrong, for their families, the consequences would not dare to imagine, so we must be careful. ”

Lasted 3 years Central European scientists against SARS study on access to important progress in cooperation

World Science report () before the journalists was held in Beijing from yesterday's "SARS diagnosis in Europe and antiviral research meetings" that lasted 3 years of Central European scientists against SARS study on access to important progress in cooperation, scientists have completed 8 kinds of SARS virus protein gene analysis, determine its three-dimensional structure and herbs and Kiwi fruit found in the natural ingredients of anti-SARS.

It is understood that the Central SARS diagnosis and antiviral research project was the first Central European scientists to peer identity in cooperation the EU Sixth Framework project, China and the EU have 4 units involved. The Chinese participants will include the Chinese Academy of Sciences, Beijing, Genome Research Institute, Shanghai Institute of Materia Medica, structural biology laboratory of Tsinghua University and the Ministry of Health Clinical Center.

As far as EU Chief Scientist, Germany Lubeck University Professor of Greek bergenfield, European scientists have completed 8 kinds of SARS virus protein gene analysis, determine its three-dimensional structure, and filter out the 24 with antiviral compounds, which are also identified with broad-spectrum antiviral activity of the compound. "This means that future research out of drugs not only valid for SARS virus, other viruses will also have resistance. ”

Professor of Greek bergenfield also indicated that, for the special European scientists excited is that Chinese herbs found in confrontation with the activity of SARS virus of natural ingredients. Institute of Materia Medica, Jiang Hua Liang researcher reveals that the natural ingredients in Kiwi, Hawthorn, oranges, etc is found in fruits, Kiwi relatively more in content. Because the ingredients do not have side effects, drug research for the future of great significance. Jiang Hua good at that as content is minimal, so it does not mean eating Kiwi can resist the SARS virus.

A mother's love can change the child's genetic code

-Tech report [] message: genetic gene has always been considered a priori determine, immutable, but recently Canada's McGill University, geneticists have study found that the mother may be enough to change our genetic code, these changes can also be genetic.

Canada's McGill University geneticists in the study control mother rat licked newborn small rodents and combing hair, final test results indicate that enjoy mother more care of small rodents more bold and adventurous. Experiments also found that the mother's care's work, because it changes a control's brain on stress response gene expression. This gene in the brain changes result in hippocampal grow more pressure receptors that reduce the body's stress response. Subsequent experiments show that this gene change is sustained, or even to their offspring.

United Kingdom the guardian which asserts that this amazing discovery means that our genetic blueprint is not finalized before birth, our body can change biology instruction, so that we can better adapt to changing the world, rather than wait for millions of years of evolution to adapt.

The resulting hair, a mother's really can change our genetic trait? a mother's love for one's real impact how much?

Modify the brain gene can lengthen your life

[] Message: scientists have long known, for mice live longer, we must let them starve, become skinny. United States scientists recently discovered that by modifying the mouse brain a gene can make it less live longer, and be able to make it more obesity. This extension of the study of human life is very good. Related papers published on 20 July in science magazine.

Strictly limited uptake of energy mice can make their life increased by 50%. Scientists have speculated that one of the key factors to mice for insulin reaction. In a half-starved of mice skinny, able to effectively use the insulin that makes them physical organization of insulin levels are very low, reducing the rate of metabolism.

In the latest study, Harvard Medical School of molecular biologist Dr. Morris White and colleagues concerned insulin receptor substrate-2 (Irs2) on the life of mice. Irs2 is found in including the brain, many organizations of protein, which helps cells to insulin response.

White team first remove the mouse chromosome Irs2 both copies of a single, 21 months later, these mice to larger than normal mice slightly heavier, in addition, these mice equally able to effectively use the insulin and longer life than normal mice increased 17%.

Next, the research team only to remove the mouse neurons in a copy of the Irs2, they found that these mice than normal mice gain of 15%, 18% of longevity, but they are suffering from metabolic syndrome — cannot effectively use the insulin, which is a prodrome of diabetes. Research Group accordingly concluded that life is composed of the brain regulating the metabolism rate and its ability to respond to insulin.

United States MIT Leonard Guarente geneticists that experiment genetic modification of mice and restricted diet of mice in sharp contrast, shows that at least two ways you can extend the life of mice.

University of California San Francisco School of molecular biologist Cynthia Kenyon said that the findings and some life researchers have only effective utilization of insulin to live longer perspective. She also said, cut the body Irs2 signaling may prolong life, but it can cause side effects such as such as diabetes.

No man, woman, so can only

-科技报道[]消息：德国哥廷根大学研究人员13日宣布，他们已利用从男性骨髓中提取的干细胞培养出了精原细胞，这一技术如最终获得成功，将可望为解决不育问题提供一种新的更好的办法。

由纳耶尼阿教授领导的研究小组从4名要进行骨髓移植的男性的骨髓中提取了干细胞，并将其与能促进细胞生长的蛋白质以及对精子发育很重要的维生素A混合，从而培养出了被称为精原细胞的精子干细胞。

精原细胞通常存在于雄性睾丸中，通过细胞分裂不断产生精子。精原细胞中有两套染色体，而能使卵子受精的成熟精子中则只有一套染色体。

纳耶尼阿说，研究小组进行的有关实验显示，从老鼠骨髓干细胞中培养出的精子干细胞，能够完成成熟精子所必需的三次细胞分裂中的前二次。研究小组将首先致力于使老鼠精子干细胞能够完成全部分裂，然后再将有关技术用于人类细胞实验。他预计在实验室中培养出成熟的人类精子可能还需要三年至五年。

对于有关研究可能触及伦理问题，纳耶尼阿说，他们进行实验利用的是骨髓干细胞，而非胚胎干细胞，这样可能会避免一些争议。

与此同时，已有专家警告说，将从骨髓干细胞中培养出的精子干细胞转变为有用的精子确非易事。另外，用骨髓干细胞培养精子干细胞的过程中，可能会产生不易察觉的基因变异，从而可能会给后代带来危险。

上述研究成果已发表在13日出版的《生殖》期刊上。

Many types of avian influenza viruses are mixed between Viet Nam viruses?

Viet Nam Ho Chi Minh City "regional animal health centre," said the youngster Meng River heads, the Centre has in poultry animals found more types of avian influenza virus. Experts worry that if a variation of the avian influenza virus continues to pose a greater threat to mankind.

Tong Meng River, the Centre has found in poultry and unusual H3 and H4 of avian influenza virus. At present, the virus samples have been sent to the World Animal Health Organization (PAHO) inspection.

Official media reports said that Viet Nam Viet Nam scientists discover is H3N4 type and H4N5 type. "Found on the avian influenza virus type, the more the more dangerous situation. "Tong Meng River says.

Scientists say that the H3 and H4 influenza viruses to poultry have died, and H5 influenza viruses, the spread of toxic smaller, slower. However, H3N4 and H4N5 virus H5N1 may and, in order to get more pathogenic.

In addition, Viet Nam, following the North of the North province and Haiphong announced after an outbreak of avian influenza outbreaks, close to the border areas of Yunnan province in China, the whole province of wood, and two County 16 April Meishan iron announced outbreaks of avian influenza outbreaks.

Indonesia also has two people died of avian flu

According to Xinhua electric Indonesia Health Minister Siti di La · law · soepari 17, said that the who laboratory confirmed and two Indonesian bird flu death, making Indonesia died from avian influenza patients increased to 7 people.

The Indonesian Health Ministry officials said that both avian influenza patients died last week in Jakarta, two female patients respectively 20-year-old and 16-year-old. The Indonesian Ministry of health received 16 late test results confirm that they are infected with the H5N1 avian influenza virus.

Currently, the World Health Organization recognized Indonesian H5N1 avian influenza virus infections has increased to 11 people, of which 7 have been fatal.

Lung cancer has six joint pain signals to the facial edema

Keywords: lung cancer six signal

[] Newsletter: current world lung cancer death rates continue to rise, one of the primary reasons is lung cancer early symptoms are not clear, atypical, easily lead to misdiagnosis or misdiagnosed. However, the cunning enemy will reveal clues, we draw attention to the following types of symptoms.

Cough is the most common symptoms. Hemoptysis is most diagnostic significance, much as in phlegm Bloodshot. Where respiratory symptoms for more than two weeks through healing, especially blood in the sputum, dry cough or elderly patients with chronic bronchitis, coughing sound or nature of the recent changes to high alert lung cancer. Examination of the chest, the exception found, such as the tuberculosis cure fibres proliferative lesions should follow-up each year, if the lesions increase should further exclude possible lung cancer of the Cicatrix. Repeated the same parts happen to guard against pneumonia, lung cancer.

As a result of the transfer to occur early stage lung cancer, metastatic clinical manifestations may first appear in the primary lesion. The following symptoms should rise alert:

Bone and joint symptoms: bone and joint pain, swollen fingers and toes terminal expansion is pestle shaped means that even has the potential to influence the activities of the limbs.

Shoulder and back pain: growth in the lung cancer lung apex, violations of bones and joints, neuromuscular, pleural and chest wall.

Hoarseness: metastatic oppression laryngeal nerve, hoarseness, sore throat and no upper respiratory tract infection of other symptoms.

Facial edema: prompt the superior vena cava syndrome. Approximately 5%-10% of patients with lung cancer as a symptom.

Male breast enlargement: male patients with lung cancer by about 10%-20% of the mammary gland hypertrophy occurs, the majority of double-side of the mast, and appear longer than the cough, hemoptysis, and other lung symptoms as early as one year or so.

World's first double arm transplant patients receive novices

Åœ — äº¬æ — ¶é — ' October 10 messages, according to foreign media reports, the world's first double arm transplant Germany farmers Carl · Melk at present recovery in good condition. He was 8, on the media that, when he recovered from surgery, found himself has made his arms, he suspected that it was just a joke, I feel like he is dreaming.

6 years ago, Carl · Melk in a farm accident lost his arms, he said, it was clear that a successful transplantation, he cannot believe. 54-year-old Melk wearing a sleeveless black shirt, new arm joints can be clearly seen. The University Clinic in Munich, he told reporters: "when I see I have his arm, I really am very shocked. This is my arm and I will not abandon them again. "Finished 15 hours after the surgery, he stayed in the clinic for nearly 3 months.

Melk recovered very well, now he has finished opening the door, open and lights, and other simple tasks. His ultimate goal is to eat and clothes, and alone on a motorcycle. Dr. Christophe · Geyer Encore said: "in short, our boldest mad hope almost achieved. "July 25-26 February, 40 surgeons, anaesthetists, nurses and other logistical personnel the 15 hours of operation, the donor's arm graft to Melk body. 6 years ago, combine the following from the shoulder and cut off his arms.

The doctor said, there is evidence that patients arm of nerve already starts to grow, but still require a two-year period he can learn how to use the hands. Melk appear in 8 press conference, his arm a bandage around, with many and shoulder pad connected tape hanging. Merk said he hoped that in the hospital for a period of 4 to 6 weeks of physiotherapy, electrotherapy and counseling, to return home as soon as possible. Although the doctor said that so far there is no sign that the immune system of exclusion, but Merk's immune system is still excluded his new arm of risk.

In response to the avian influenza outbreak scientists try to increase vaccine effectiveness of auxiliary

According to the science and technology daily, February 20, 2006: in order to prepare large outbreaks of avian influenza, biologists have turned to the so-called auxiliary agent development.　　This is a way to add to the traditional vaccines, to increase the effectiveness of the vaccine. Auxiliary agent make a small amount of vaccine produced a strong effect, they let the immune system to focus on the effectiveness of a fire protection materials — Antigen. Some auxiliary agent even increases the immune, immune time extension. Scientists are still not clear how the auxiliary agent to do this, but they know, auxiliary agents might dilute the vaccine does not reduce its effectiveness.

Since 1925, auxiliary agents found vaccine, auxiliary agent mechanism has been puzzling. It sometimes produce utility, sometimes dangerous results. At present, in order to prevent the H5N1 virus and three other avian influenza viruses, scientists plan 2006 19 flu vaccination in clinical trials, including 17 vaccine contains auxiliary agents.

Many auxiliary agent simulation known part of viruses and bacteria, to trigger the complex process of several important stages. In the process, the immune system fight off the invading microbes, and then store the information, the same microorganism invasion and then appears, you can make them produce more speedy and defense. Known to have an auxiliary agent belongs to the low-skilled, are a family of easy soluble aluminum salts, are collectively referred to as alum, vaccine Antigen obviously attached to the aluminium salts.

In 1999, Chiron Corporation found that a pilot fight avian flu vaccine add shark oil auxiliary agent MF59, in doses as low as 7.5 mg, twice-injecting, provide preventive effect. In December 2005, France a vaccine manufacturer announced that its experimental vaccine against the H5N1 virus contains alum auxiliary agents, the use effect is good.

The current problem is that adding auxiliary agent of MF59 vaccine has not been approved by u.s. official. If approved, patented by MF59, will make each vaccination costs.

By contrast, the cost of alum auxiliary agent cheaper is not patented, and was United States food and Drug Administration approval. Two years ago, Germany researchers test a vaccine containing aluminum sulfate, the influenza virus is killed. In the low-dose 1.9 mg, the vaccine can be 80% percent of the people.

Placenta stem cell bank: Bank storage health

Keywords: placental stem cell bank storing a healthy bank

[/]: 23 November, 11-year-old Yu Yi Xuan in Concord for surgical extraction of stem cells, these precious "seed" transplanted into their mothers living with leukemia. Recently, this strong young became media hot spots, he took the initiative of the recipient to save the mother's story touched many people.

They are lucky. It is reported that children and parents the chance of a successful bone marrow matching almost equivalent to the lottery, not to mention the people who know each other, so both in films and TV programs or in real life, there are so many people struggling waiting for proper bone marrow.

"If the baby placenta stem cells save up, later encounter similar disease cure hope. "" Human placental stem cell Bank, "said the Chief expert yukui. Just like banks, deposit, usually when they are needed.

Stem cells: cells

Stem cells have extraordinary regeneration capacity, can generate a variety of specific differentiation of functions of cells and tissues and organs, this is its two fundamental characteristics.

Extraordinary regeneration capacity so that the stem cells can be split into a large number of cells that meet medical needs, because using stem cells to treat a disease, usually takes up to millions of cells.

The differentiation of the generated function cell can play an important role in the treatment of specific diseases. Yukui said that can differentiate into red blood cells carry oxygen, differentiation into islet cells produce insulin, etc. Because of this characteristic, stem cells are referred to as the "universal cell", a biomedical research.

Stem cells are a few different sources. The first source is the early embryo, that embryonic stem cells, it is in early human embryo — blastocysts (fertilization after about 5-7 days) of undifferentiated cells. Secondly, the stem cells derived from adult individual organizations, such as bone marrow, blood, fat, etc., but this little number of stem cells. In addition, the stem cells can also come from baby placenta and umbilical cord blood.

Due to its characteristics, stem cells become overcome many of the regeneration of one of the important direction. "Some diseases cannot be used with drug therapy, such as the spine broke its own grows again, another example of senile dementia patients is brain cell function degradation, drugs are also resumes, while these functions are possible through stem cells generate specific functional cells to recover. "Yukui said.

Unsafe animal serum

According to reports, placental stem cell differentiation is less profitable than embryonic stem cells is slightly lower, but not the ethics of embryonic stem cells; compared with umbilical cord blood stem cells, a placenta weighing about 700-800 grams, umbilical cord blood is only 80-90 grams, the number of placental stem cells more; and bone marrow stem cells, placental stem cell differentiation of better, and do not need to invade the bone marrow samples.

According to the international yukui describes many stem cell Bank, the majority of these stem cell Bank has a cord blood bank. The start is the cord blood collected direct freezing, and then start the umbilical cord blood in nucleated cells isolated from culture, built in umbilical cord blood cells library. And until recent years, from the umbilical cord blood cells in further isolate the stem cells.

But so far, almost all of the stem cell Bank are private, not public, that is, his own cord blood stem cells saved only by his own use. Since the second half of last year, some of the largest umbilical cord blood stem cell Bank also proposes to establish a placental stem cell Bank, but is still not suitable for clinical application.

So, what kind of stem cell bank meets the clinical application of criteria? yukui said, clinical application of the standards are more complex, such as stem cell culture process of stem cells to keep non-activated charging body, cell groups, to pure, etc, but the most basic, no cell is saved to the animal source of exposure.

At present, domestic and foreign many studies have used animal serum to culture cells, this is a likely source of imported animal virus material, but the current technology does not detect its potential danger. "We chose human umbilical cord blood substitute animal serum, and joining the different growth factors that ultimately proved very optimistic. "Yukui said.

Russian Tycoon injection infant skin stem cells as baby scar no trace

Russia multi-millionaires are their investment from luxurious luxury yachts and jewelry to a stem cell beauty. This isn't a normal stem cells, but from an abortion baby extract stem cells, and then injected into their body, hopes its youthfulness. Fetal stem cells therapy not only eliminates wrinkles and can reduce body fat and loose skin treatment.

Russia billionaire, former President of the pharmaceutical giant, candidates, 58-year-old Vladimir · Hebron Zaitsev said that, although the anti-aging therapy is still in experimental stage, but he himself has become the drug of the true believer, each spending 2000 pounds. He said: "I have already filled the wrinkles, but now my skin as smooth as a baby, even me boy left of horrific scars are gone!"

But Moscow heart Professor Smirnov said: "this is still in a test phase of the therapy is not only the risk of potential is huge, and is against the law. "They point out that at least one person in the use of this treatment shortly after death.

Another Office, from is currently investigating a case of illegal transactions in which the fetus can understand that some Russia and surrounding countries poor women, 100 pound put abortion baby sells those unethical doctors. The fetus is frozen and then to 5000 price reselling to beauty salons, and the development of more mature fetal selling expensive, because the beauty salon personnel believe that stem cells have a greater medical value.

Moderate drinking cannot prevent heart disease

Beijing Youth daily April 3, 2006 reported in recent years, many scientific studies show that moderate alcohol consumption can prevent heart disease. Such as daily drink two glasses of red wine, can reduce the risk of coronary heart disease. There are a number of scientific studies show that moderate alcohol consumption may reduce the incidence of some cancers. However, the United States scientists new survey results indicate that, in moderation does not have to reduce the occurrence of heart disease.

In this study, United States researchers on past national scientists do 54 items and the related research provides an analysis of the results. The researchers found that in these studies, only 7 study differentiates themselves choose to quit drinking, and because of health reasons, had to give up drinking. Therefore, when these studies show that drinking ' mortality than moderate drinkers of mortality is higher, you can explain why you should be certain alcohol, because of their State of health worsened and his drinking, rather the contrary alcohol on health.

Researchers also found that encompass their choice of long time not drink alcoholic beverages of 7 study, drinkers and non-drinkers in the incidence of heart disease have no difference.

The researchers said in the past generally believe in moderation may prevent coronary artery disease is not only the world's wine industry has great impact, but also have an impact on the world of the doctor to the patient's clinical recommendations. Their findings show that doctors in some patients with moderate drinking drinking some alcoholic beverages extra careful when required, because the actual health effects of drinking now looks not as originally expected.

Researchers also said that the reason people quit drinking, you can have many because of their poor health conditions, temperance, or because the use of certain drugs and not drink or because alcohol allergy, not to drink. Therefore, people doing similar research should be a distinction in these factors into account. Although people think older, often have some small wine than drinking peers to health, but their findings indicate that, with age, many people because of health reasons is not as young as you can drink. So, can drink map is a kind of drink, health, and not because of alcohol consumption and makes drinkers healthier such a causal relationship.

European experts made H7N1 avian influenza virus vaccine

Popular words: avian influenza meteor shower Jinghua smoke

Xinhua Brussels October 27 Feb 27-the European Commission announced, by the EU institutions, sponsored an avian influenza research breakthrough, multiple European countries experts developed a H7N1 avian influenza virus vaccine, the vaccine will conduct clinical trials in spring next year.

The name of "RD-3" vaccine by the United Kingdom, Italy and Norway's influenza experts, as well as France a pharmaceutical company of vaccine experts after four years together. H7N1 virus is highly pathogenic, cannot be directly used to manufacture the vaccine, so expert uses a feature called "reverse genetics" technology for a reconstruction of the virus. Renovation of the virus has adopted the international safety testing, then research staff and avoid the use of meat, poultry and egg production was able to resist the H7N1 virus vaccines.

According to local media reports, in 1999, H7N1 virus has caused avian influenza outbreak in Italy. Research suggests that this virus can be transmitted to the sick, but it raises an avian influenza pandemic H5N1 probability is relatively low. In the EU 27 daily briefing, spokesman Philippe · Todd explains that H7N1 virus vaccines in September 2001, then started to develop European experts are not sure what a virus can cause avian influenza pandemic.

Craniotomy surgery controversy for detoxification and the younger than death?

Craniotomy drug operation

Yang Xun dead, families in his ashes found rusty screws. His father Yang Wu said that, if not protected by the hospital and some media misleading, perhaps, Yang Xun does not go so fast.

In order to investigate Luzhou medical college affiliated hospital (hereinafter referred to as "luyi hospital") of craniotomy drug operation, within a week reporter interviewed 16 was in the hospital for treatment of patients. The sequencing of the interview, Yang Xun is 6 months.

Prior to this acquisition of five "addict" parents have consistently reflected in the finished after craniotomy drug operation, their children repeatedly appear world-weary suicide, some even more by action, fortunately failed to "trick". They referred to the Yang Xun proves no lie.

Yang Xun, 26 years old, has eight years of drug abuse history, 1 October last year, luyi hospital after craniotomy rehabilitation after surgery for more than a month, he married with Rodin, 4 months later, he period falls from Yunnan detoxification died.

■ Treatment failure to seek treatment

"Yang Xun's death, luyi hospital craniotomy drug operation failed in extreme cases. "After this narrative, Yang Wu mood quite excited.

"Yang Xun was my only son, grew up on his comparison to spoil it administered. He was sent to mandatory drug addiction treatment centres several times, but did not work. 14 July 2004, I see Chengdu a well-known media reports said: a sector delegate to Luzhou medical college affiliated hospital of ' brain stereotaxic surgery in treating drug clinical and basic research on the topic, ' a success as two addict destroyed the addiction. We are a happy night, newspaper, luyi affiliated hospital of technology reached the advanced level of the country, surgical treatment success rate of 90 percent, while engaged in the operation of neurosurgical Director, known as the Southwest surgery drug first person of Dr. Chan Lai has just been introduced to has 17 years of clinical experience. "" June 27, finished the surgery, the third brother because too many targets, have been in a coma, the hospital has been to his injection of tranquilizers. From ' wrap to psychiatric, then go to rehabilitation, until 31 July, because three brother almost from luyi hospital building, suicide, I am in agreement with Mr Li gang, the third brother back home, but do not run out of hospital procedures. ”

Zhao said, zhaoxue Jeffrey accepted after the surgery, the eye no glimmer, unresponsive, emotions are often out of control, the ability to distinguish right and wrong have also become very poor. "Come back a few months will relapse, but Chan Lai has just said we can't go back to the hospital, to be paid back. ”

■ Surgery junkies have bigger

Yang Xun family still regrets that they did on multiple "mind," Yang Xun himself is willing to do surgery, completely free from addiction, the whole family on a new life full of yearning.

2004 August 9 in the morning, Yang Xun was shaved head, lying on the operating table. 3 hours after the surgery, he went back to the ward.

"After surgery of Yang Xun was very excited, dance, 6 individuals according to he, in his mouth with delirium: drill drill drill my head, good sound, good Coke smelly drill, Ah, I feel good hero, Professor Chen (Chen Li had just referred to) says I screw up, and you want to back up ..."

"I'm worried about, but it doesn't matter just Chan Lai, a small operation, a few days we will be able to discharge. ”

Yang Xun gradually restore the calm effect on speech, August 16, family hope back to Chengdu.

"Back in less than a week, I found out that he has constantly had headaches every day to wash two head, hard to dig out the operation, said screw. He said no smell or a taste, mood is beginning to feel, to run, I doubt his relapse, but haven't been able to capture the scene. In order for him to stay away from drugs, I will give him locked in the House, also especially welding an iron door. But he ran out, he's crazy, a few times over the fence, jump from, I found out about it. "Yang Wu said.

Soon, Yang Xun to Rodin, acknowledging relapse because secrets were discovered, Yang Xun initiated public drug, he was surprised to find that the surgery just drugs, but instead to the amount of injection, and increasing consumption of 100 day related money before, with increased to 1000 million.

At the same time, Rodin also found Yang Xun's desire to begin a steep decline. Yang Wu, so will the son to Luzhou, reflect the operation fails, call the redo operation. But not long before, the Ministry of health, emergency stop a craniotomy drug operation, this surgery side effects reported overwhelming.

"I realized that the operation failed, sent his son to voluntary drug addiction treatment centres, for the first time, not to the drug addiction treatment centres, who ran for the second hand, second day, ran away, said surgery treatment have failed, there was no hope. January 9, 2005, in order to allow another Yang Xun drug-free environment, no longer in contact with friends, I will send to the Yang Xun me a friend's House in Kunming, while Chinese herbs detoxification. However, 14 January, Yang Xun just falls from. ”

"When you see a newspaper the day after I arrived Luzhou. I am going to visit. I met luyi hospital first accept the craniotomy patients in rehabilitation, he is zhaoxue Jeffrey from 27 June to do surgery, Chen Li gang and zhaoxue Feng Zhao, all of the sister that he is free to treat.

"I asked zhaoxue Jeffrey also like drugs, he said: do not want to, but I think he is slow, the brain doesn't seem too normal. Chan Lai has just explained that Cho was the first case because, so the operation ' call ' 17 targets, you might need one or two years of restoration. I then want to track and see if he was relapse, but Chen ceremony just stated many times that do not agree to the families of drug users contact each other to avoid drug users contact each other, can't stay away from drugs that cause addiction treatment failure. Later Yang Xun was wrong, I have heard about, zhaoxue Jeffrey finished surgery soon relapse. ”

Reporters later found zhaoxue front girl

-Mei Zhao, she confirmed the Yang Wu. She said: "is my third zhaoxue Jeffrey Costa, 10-year history of drug abuse. In July 2004, Mr Chan Lai has just three brothers to a friend of Sen., we introduced the craniotomy drug operation, said operation on the human body does not have much impact, relapse and very small, we'll go. Chan Lai has just said, because it is the first case of surgery, for publicity, so free treatment.

Yang Wu said: "Yang Xun cremation, the ashes of the he found several metal, there are still a few screws rusty. This is to understand why he has been called a headache. ”

Chan Lai has always denied surgery fails, he said: "a small number of cases is not able to explain the problem. Your medication has no effect, go to the drug addiction treatment centres also can't. I have the surgery, even if only 20% of success are successful. ”

■ Yang Xun encounter is not the case

Dadukou district, Chongqing, one called the week of 28-year-old woman on stolonifera, because in Luzhou medical college affiliated hospital of craniotomy drug operation "failure", her emotions out of control, to 21 March this year, from the fourth floor of the residential building and well jump off, fortunately did not break, but caused a coccyx bone fractures.

In September 2004, Zhou Ying in Luzhou accepted the craniotomy. Operation end, woke up, she suddenly found sense of smell, appetite begins to decline. She thought it was temporary, however it is still not resumed, and soon started to decrease rapidly, in memory of migraine.

"30, I leave the hospital, the total spent $ 3 million. But a discharge I'd drug, my mind was: running out, the operation failed. ”

■ Controversy in the craniotomy drug operation

Craniotomy drug operation is halted and a half years of the Ministry of health, the dispute continued for more than half a year.

"Itching" has always been plagued by one of our double sociology and of medical challenges, crosses cut off the majority of drug users towards new journey. 90% of the rate of the number of people on treatment produces "futile" of despair.

In the past, we put drug addiction as a bad habit, but now in medicine there is a new understanding: this is a chronic recurrent brain disease.

In 2000, the craniotomy drug operation in Guangzhou, attracted a "miracle" by me, 2004 this surgery was pushed to the climax, many drug users as the last straw.

As of 2 November last year, the Ministry of health emergency stop the operation, the country has over 500 cases of operation, more than other countries in the world for the calendar year accumulated over 300 cases. Guangdong, Hunan, Sichuan, more than ten provinces progress in full swing, the families of addicts, and even went to the hospital knees crying for the doctor to perform the operation.

What is the drug of craniotomy? it in reality is a borrowed for scientists from Russia, was first invented, the use of medical equipment, determine brain drug craving district "addiction" position, the high temperature inside the fine needle into the brain, damaging drugs itching "craving zone".

In fact, prior to the birthplace of this technology in Russia, because of the "invalid operation for patients and have side effects," charged but was aborted, yet lifted.

We need the image to a "desire to destroy operation zone," called the "target". However, for the operation of the national hospital, a target are not identified in the standard, there are seven or eight and up to a dozen, than Russia's technology complex. While the target the more unknown side effects. This is the operation is halted.

More than half a year, in view of the Ministry of health of stop, controversy continued, some hospitals "longing" Ministry of health of the lifting of the ban, some hospitals have more cautious stance.

Shortly after the halt, Ministry of health requested, in particular the operation of Guangdong Province and the provincial Department of public health research organization experts to develop a scientific evaluation of the programme, to have surgery patient observation and follow-up, objective scientific indications to identify the operation, security, validity, on the basis of this drug to brain surgery clinical application and in-depth study.

In March of this year, the Ministry of health was held in Xi'an surgery drug clinical technology seminar, subsequently, craniotomy drug operation is expected to release in October of this year's news, but in the midst of controversy, the Ministry of health and to be a denial of the month April.

■ "As a new

The introduction of technology, this effect is very good. "

The reporter tried to some operative craniotomy drug users interviewed reflected problems, but of Luzhou medical college affiliated hospital publicity Bureau Luyi Chief Lee said that all interviews are required by the provincial Department of Health Office of science and education.

May 30, Sichuan Province Department of science and Education Department Director of Chan, Ministry of health asked by answer, Sichuan province hundred accept craniotomy surgery's return visit to the detoxification work has commenced on the morning of 31, project assessment team will be on the first stage of the work, there will be someone luyi affiliated hospital, "can be interviewed, the expert group discussed the decision".

31 October, the Commissioner reply cannot accept any interview, he explains, the medium before stage drug off skull surgery "sequel," reports have given negative impact assessment work.

Made a total of "luyi 158 cases, only a dozen cases of complaint, this is normal, this morning, the overall results of operations of Sichuan province is very good, luyi said many people send them the flags. ”

"Many successful cases, as a new introduction of technology, this effect is very good. "But the Director Chen declined to disclose the specific data.

Why only a very small number of people infected with avian influenza?

As of April 2006, and death and destruction of tens of millions of poultry feathers that my compared to human infection of H5N1 avian influenza occurs only 18 cases, of which 12 have been fatal. The Ministry of agriculture, livestock and poultry diseases key laboratory experts, academician Liu Xiu-Vatican today in the academicians of the General Assembly on the above data for comparison, and a detailed explanation why only a very small number of human infection with avian influenza viruses.

Liu Xiu-Vatican said that in March 2006, has two independent research teams in the Nature and the Science of published articles, well the answer to this question: the human upper respiratory tract (from the nasal cavity to bronchial) mucosal epithelial cells without medicine avian influenza viruses of α-2, 3-GAL receptor, with only a combination of human influenza virus in α-2, 6-Galactose receptor.

Liu Xiu-Vatican said that the H5N1 subtype as by gene mutations, or to get to be combined with upper respiratory epithelium α-2, 6-Galactose receptor capacity, you have the possibility of human infection is greatly enhanced.

In his view, the treatment of human infection with avian influenza, there should be a scientific and rational manner. Now the H5N1 subtype viruses cannot infect the vast majority of the population exposed to very few people could be infected, but does not infect other people. Now the H5N1 avian influenza virus, when changes to-human transmission of pandemic influenza virus, its severity, are unpredictable. Human beings have to do is to minimize the occurrence of human pandemic influenza, and in this kind of dangerous preparations before the arrival.

Liu Xiu-Vatican also stressed that, in the last ten years, almost all humans are sources of new infectious diseases in animals, repository, almost 60% of the human pathogens as zoonotic pathogens, 75% of emerging human diseases as zoonosis. Therefore, control of important animal diseases, control of human disease have important public health significance.

Brain scan may predict schizophrenia risk

A research group, University of Edinburgh in BMC Medical Web site recently published an article saying that the brain scan can detect central nervous system gray matter (i.e., delivery information, facilitating storage memory of brain) changes, which can help doctors predict risk of onset of schizophrenia. The article says that by observing changes in central nervous system, gray matter, those family reasons most likely suffering from schizophrenia have preventive detection. In other clinical analysis, using magnetic resonance imaging scan method, you can display the brain dysfunction in patients with symptoms prior to predict their suffering from schizophrenia risk.

Edinburgh University research group used a 10-year time tracking the 200 most likely suffering from schizophrenia, these young family members for at least 2 people are diagnosed with this disorder of brain function. The researchers analysed the including 65 human brain magnetic resonance imaging scan (scan every 18 months), looking for changes in central nervous system gray matter. This 65 people in eight people in the first scan about two years later on schizophrenia.

However, the researchers pointed out that their research has covered only a small group of people, you also need to carry out large-scale independent testing to confirm these results.

Change head with sad technology ethics clearance nerve fiber cannot be born again

The strange tales "in such a story, Lu Ling Yang Scholar Award Jules found Dan's heart hair orifices are stuffed, so thou didst pick a replacement for him. From daejin Agur Dan Evans, and soon, the first name in the scholar, a study of successful again in the fall. Later, when Jules Dan mentioned his wife face not beauty, Lu sentenced and surgeon to Zhu wife swap on a beauty. At that time this is undoubtedly the ancients unfettered imagination. But now for the heart, lungs, spleen, kidneys, and so have become a reality,

The poll, is also able to change it for? "-head of" from us how far? it is not possible in fable, or in the near future will be able to achieve? in medicine "header for" footsteps and advance to the next what?

Getting at the root of the Exchange was a great hit in head fake news

In 2001, a surgeon in the United States physician for head of news had to make a lot of heated discussions, this also gives the public full of curiosity and anticipation of experts excited, but the final result was undoubtedly gave this is ice period of "head of" reduced temperature. In multi-party verification, we found that he was severely "swiping" a turn, it's just a "making" false news, is the author in order to highlight the buzz, the United States a neurosurgery experts Dr. White United States in the scientific man magazine published an article on the possibility of human head transplantation, graft of the article quoted out of context.

However, white in his article does say that, as early as 1970, he and his assistant have first primates — has changed in rhesus monkeys head surgery, surgery of rhesus monkeys live for eight days, not only has a consciousness, and you can eat, eyes can follow people move around indoors. His research group have also been ported to the human head has taken the first step. They produced a kind of device, you can put in circulation of blood to the head temperature is maintained at 10 degrees Celsius, so that the brain metabolism slows, to let the skull in the blood supply is cut off after 1 hour, saved as "head of" the implementation of the valuable time. Articles published in white, also referred to the one called the Vito Horwitz, this person as a diving accident cause limb weakness, and an interview with white is known first willing to put his skull donor for white people used operation.

Surgery pain

Difficulties of a nerve fiber cannot be born again, "the head of" can only be on paper

If you want to add a skull and strange body connected, first of all to vascular suture, which is in modern medicine is not a problem, but cannot be linked to successful nerve bundles? you know, the brain and spinal cord is human nerve centers, human neural activity is in the neurons in the cerebral cortex by issuing instructions, through the spinal nerve, and then transfer to the activities of the organ and, therefore, is the surrounding the spinal cord and the brain activity of organs of connection Centre, in the neck to a few square centimeters of the cross-sectional area of the body all the nerve fibers. "Nerve fiber specifically? can say countless, then good doctors and machines can connect one is reattached, broken nerve fiber is not re-growth. At least the current face of cervical spinal fracture, medical institutions throughout the world in the clinic on the powerless! "Tsinghua second affiliated hospital neurosurgery Director Chan Kwok-keung stressed that all the nerve fibers could not be broken," the head of "can only be on paper.

No independent life, head of meaningless

Institute of Tsinghua University brain diseases, Dr Sun ZhaoHui, brain death is not very difficult, as long as you keep a supply of oxygen in the blood. That is, people are now aware of the so-called "header for" just put important blood vessel, the plugs in modern medicine is not difficult. But to have independent life, is no easy job! if "head of" the survival of future generations depends on respiratory machine, pacemaker maintained, then the operation will have no significance.

The so-called success of "head of" minimum patients can be spontaneous breathing, heartbeat, even independent independently. But human command central respiratory and heart and not in the brain, while in the medulla oblongata, simple understanding was high in the neck, that is, we often see on television, which was a hit in the neck, can be collapsed in directly to the site. "Head of" at least to wrap to the medulla oblongata, current knowledge of the medical profession is fibers within the medulla oblongata cannot be regenerated. Sun Dr, is like a tree, the branches can fold a long, tree trunks to cut off there is no way. The medulla is the animal, the old hub also controls the animal body all original reflection activities, etc., on which more in-depth and specific research is still ongoing.

Prospects for peripheral nerve surgery to repair just around the corner, as "head of" kindling hope

"Head of" distance we are still very far away, for accidents occurring in patients with nerve damage, faults in the current medical standards can solve the problem?, Beijing, China-Japan friendship hospital neurosurgery to Professor of ice told reporters that in previous General view is that there is a tendency of the nerve is a nerve injury cannot repair, but with the development of medical science, conquer peripheral nerve repair is already within reach. What is peripheral nerve? that is in addition to the brain and spinal cord nerves, the remaining parts of the body belongs to the peripheral nerves. The Professor himself was devoted to the study of "Chitosan catheter bridge peripheral nerve", in short, it is when the peripheral nerve injury, in the context of 2 cm, the closer the better, of course, hollow with a small pipe to rupture

Neural ends, through drugs cause nerve regeneration.

The study is already in rats, monkeys, and other animal experiments successfully, you have to enter the human clinical trial stage. Can doctors face "head of the nerve centres of injury" or helpless, because the nerve centers more more sensitive than nerve, it's not like the peripheral nerves outside a layer coated, peripheral nerve provides a layer of protective sleeve. And so-called "header for" success, no doubt is to resolve cervical spinal neural connections, re-growth. The Professor of ice in the development of modern medicine, many of which may not be realized.

Expert perspectives

Tsinghua second affiliated hospital neurosurgery Director Chan Kwok-keung:

Current medical standards, references to "head for" it remains to be questionable, at least it from our scientific level is still very far away. People in the face "of the head of" the first direct question is ethical problems, first of all, there are more of a donor? at least in China of the medical profession, unheard of. If so, assuming that the "head of" final operation succeeds, then let the emotional brain control to dominate a strange body express their feelings, as a doctor, I think it's hard to imagine!

Tsinghua University, Institute for brain disease: Sun ZhaoHui

Due to the current international yet "head" of the actual surgery, according to current scientific and theoretical basis, if you really just "heads" that can guess a postoperative patients can only rely on the machine to sustain life, instead of independent life, is to change what's the point?

Fashion and beauty of the great handbags and shoulder back pressure and bad woman

-科技报道[]消息：大手袋受到不少职业女性青睐，但随之而来的健康问题却为她们敲响警钟。

女士手袋正向“大而重”的趋势发展，这种手袋虽然时尚美观，却会给携带者的颈部、肩部和背部造成不小损害。

得克萨斯州加兰贝勒医疗中心的萨德勒说：“女病人向我抱怨脖子痛或头痛时，我通常会称一下她们的手袋，大部分手袋重量在3.1千克至4.5千克之间。如果继续这种‘大手袋’热，会有更多的妇女罹患类似疾病。”

临床医学家凯斯认为，妇女们应当注意挎手袋的正确姿势，背要挺直，肩要放平。按摩、消炎药和适当休息可缓和不良症状，但最好的治疗方式是培养女士们的良好习惯。

路透社说，事实证明，一些传统的负重方法如头顶篮子、把重物放在后背上，要比挎大手袋健康得多。

High-tech application ready to stop bleeding body

World Science report () before the current in haemostasis is unsatisfactory, the recent Ellis · Ben, and other experts of two high-tech hemostatic effect by the new Act confirms that the application of the human demoralization

"Surgeons in half the time on the operating table are used in the hemostasis. "As MIT's Department of brain and cognitive sciences expert Ellis · Ben said, the bleeding will in a short period of time claimed the lives of people, although the hemostatic forceps, cauterizing a wound, contraction of blood vessels, and other drugs are present, but the Haemostasis is unsatisfactory. Recent Ellis · Ben, and other experts of two high-tech hemostatic effect by the new Act confirms that the application of the human demoralization.

The birth of the person that they will not only change the surgery process, but also on human medicine development play a crucial role.

Nano-fiber, hemostasis in just 15 seconds

Nano-peptide protein fiber was just being used as a hamster brain cells to do the repair, scientists have discovered in the course of the experiment it magic hemostatic effect. In October, the United States at the Massachusetts Institute of technology and the University of Hong Kong Faculty of experts in collaborative research, found that the Nano protein fiber liquid can quickly stop the bleeding.

This liquid is mainly composed by peptide, contact to cuts, will self aggregation into a protective transparent gel, like barrier closed wound, so as to achieve the hemostatic effect. At present, scientists have found in a range of mammals, from the rat started test to the test of pigs, the organs and tissues including the brain, skin, liver, spinal cord, leg artery and etc. "It's effect very quickly," Ellis · Ben said, "even if the animals have taken the drug diluted blood, this liquid, it is still possible for 15 seconds to stop the loss of blood. "Because this nano coagulation protein fiber on the cut is transparent, so the operation without removing it, avoiding the possibility of contamination of wounds, which its future in aseptic conditions for operation of offers. In addition, Nano-peptide protein fiber weeks in organisms automatically degradation as a normal amino acid, is the surrounding cells absorb, non-toxic, non-side-effects, but also do not cause the body there is usually of rejection. Compared to the current military Hemostatic agent on common, this liquid with the advantage that no matter how deep the wound or how strange shape, have no effect on its results. According to Ellis · Ben said, they have been published on the Internet, this new and ready to send the details of the results published in the December of the Nano-medical science magazine.

However, let scientists puzzle that they have no way of knowing this kind of substances in organisms is how to play the role of the magic, because the most basic principle of hemostasis is to make the cut into blocks of blood clots, Nano-peptide protein fiber but this is not the case. Therefore, Ellis · Ben conservative estimated this liquid really applied in clinical treatment of patients with at least 3 years, and first used in the battlefield and traffic accidents in first aid.

Although everything is not yet upon us, many surgeons have already expressed an interest. United States Beth Israel Deaconess Medical Center in gastrointestinal diseases Director doctor Orem · check too, just very promising Nano protein fibers in the treatment of gastrointestinal bleeding at the time of application, he excitedly said: "this is exciting discovery, we can use the simplest method to stop bleeding. ”

Ultrasonic tourniquet, battlefield emergency new weapon

Its shape is like a shirt cuffs flanging, once the bleeding, it tied the wounded limbs, in a few seconds of blood will be stopped – this is the depth of the ultrasonic tourniquet, initials DBAC, United States, the Pentagon has allocated $ 5100, dedicated to the development of this project.

New York Institute of Philips ultrasonic imaging and therapy expert Michael · Pasi Lei said: "according to the United States a report by the Pentagon, hemorrhage damage is caused soldiers on the battlefield the leading cause of death. "The United States Defense Advanced research projects Agency was organized by the United States National Institute of the class to complete this project and look forward to 4 years into military applications.

"Ultrasonic tourniquet's main role is to gain time, reduce the amount of bleeding. "The University of Washington's applied physics laboratory ultrasonic industrial medicine research center of Lawrence · Qom in this field for ten years of experience, he believed that" rapid hemostasis in ultrasonic, doctors have enough time to use a better device for a thorough treatment. ”

Ultrasonic tourniquet is mainly composed of ultrasonic imaging sensors and sensor with two parts, it has become the battlefield of the new weapon, heal depends on its core technology — high-intensity focused ultrasound, or automatically HIFU. Once tied bleeding limb, tourniquet ultrasonic imaging sensors according to the body's blood vessels automatically detect the location of the wounds on the body. And then by treating the sensor frequency emission automatic focusing to confirm the location of the wound and then given HIFU, wound discharge of blood in a few seconds the instantaneous condense into blocks. At the same time, HIFU this technique in the treatment of cancer clinical trials also has excellent performance.

Although ultrasonic tourniquet human physiological use feasibility has been sufficiently proved that, but the battle is far from the laboratory for severe and complicated. Therefore, to plunge into the military field applications, ultrasonic tourniquet also must pass a temperature, dust, noise, moisture affects a series of rigorous tests.
