Discovering the enzyme which changes the B type blood into O type

A, discovering the enzyme which changes the B type blood into O type


 In only the person of the same type of blood the method of changing into the O type which can be transfused by anyone was discovered the blood of A type and the B type which cannot be transfused. If safety and effectiveness of this method are verified, insufficiency of the blood for transfusion can think also that it becomes past ones, expectation and interest are moved aside. This knowledge was published to scientific magazine “Nature Biotechnology” April 1st online edition.

 Most people, have either inside four types of blood A, B, O or AB. At cell level, there is the respective individual sugar molecule on the surface of the red corpuscle of A type and B type, with AB type the both sugar molecule of A and B exists. For example when the blood of A type you transfuse to the person of B type, this sugar molecule becomes “the antigen”, induces the fatal immune reaction. However, in the circumstance of the emergency which does not have the room which as for the blood of O type because it does not have this “antigen”, it can use safely by anyone, the type of blood of the especially patient inspects it is useful. Because of this, if the blood of O type is used and more than other type mentions “blood insufficiency” you say that it means to mean the insufficiency of O type.

 In order to cancel this insufficiency, removing the antigen of A type and B type from the red corpuscle, the technology which it changes into O type becomes necessary. If the enzyme is used, it was thought that it is possible, but those where the enzyme which designates just the antigen of A type and B type as the target is discovered were difficult problem. Test was executed in the past, the American ZymeQuest corporation (Massachusetts state) concerning the enzyme which was refined, if, but the antigen remains even from 1%, it was found that the immune reaction occurs, the good result was not obtained.

 Two bacterial enzyme families which are called the glycosidase where in the latest research, the team of Henrik Clausen doctors of the 0 0N Harvard University medical department and the Copenhagen university, inspects the database of the bacterium and Eumycetes thoroughly, can remove this sugar molecule as the target were discovered.

 The american blood center (ABC) Louis M. Katz doctor concerning this enzyme “has the necessity to advance regardless to clinical test”, that although it does that several doubt remains, you express, you point out the possibility the little residue of possibility and the enzyme itself where the immune reaction happens the enzyme vis-a-vis the red corpuscle which was processed causing immunity obstacle. In addition, Katz touches concerning the problem of cost, when the one which applies the fund which is necessary for the enlargement of this kind of technology, to the collection of the blood donor is good, it has expressed also viewpoint. Presently, every year 5% of population has donated blood, but if this becomes 7%, blood insufficient problem when it is the expectation which is cancelled Katz has expressed.

Asthmatic risk increases with weight increase

Asthmatic risk increases with weight increase


 As for passing weight and the person of obesity, it made the asthma clear in comparison with the person of standard weight, was published to the medical magazine “American Journal of Respiratory and Critical Care Medicine” April edition that it is easy to emerge. The research group when tackling asthmatic management, has expressed that it is necessary to keep seriously considering proper weight management.

 The American stand hygienic laboratory (NIH) according to, as for the asthma in the inflammation of the windpipe and the chronic disease which accompanies strangulation, as for healing it is difficult, but there is many a thing whose management is possible. Repeatability ringing , (the weir), there to be a condition such that it is easy to cause the allergy, the number of affection in the United States people includes child patient 9,000,000 and is called approximately 2,000 ten thousand people. According to recent investigation, obesity or it passes American 65% and it assumed that it is weight, also connection of the asthma and obesity was shown in former research.

 In the latest research, the American stand Judean medical research center (Denver) E. Rand Sutherland doctors, in 1966~2006 year above the total 330,000 3,000 people targeting examined the data of 7 research which were inspected BMI (obesity exponent) with concerning the asthma in the United States, Canada and Europe. It hit to the review, under BMI25 “standard weight”, “passed it adopted the 25~29 and, weight” and the standard scale which makes 30 or more “becoming fat”. As a result, BMI as for the person of 25 or more asthmatic emergence ratio 50% is high, weight increases following and you say that also risk increasing was ascertained. As a result man and woman difference was not recognized.

 The research group have assumed that passing weight dangerous factor (the risk factor) with has the necessity to add the asthma to one of the disease which becomes, on the basis of this knowledge. When obesity or it passes and thinks of the population of the weight person, as for American who has asthmatic risk rather than being thought so far, several 1,000,000 people mean many thing, but you say that there is also a possibility where annual 250,000 can decrease the asthmatic patient with “substantial loss in quantity” on the one hand. But, unless it passes and there is no disease depending upon weight, because decrease of lung capacity and restraint of the breast-wall is pulled up, there being a breathing apparatus condition, always, the asthma it limits, the specialist has expressed.

 Another specialist in former research lists the fact that it is not made clear concerning man and woman difference, the latest research has expressed at this point in time that it is interesting. It is difficult to make the causal relation clear, whether the asthma of the not yet diagnosis which is from or the time before where obesity really becomes cause of the asthma with obesity increase badness it does but obscurity, that obesity is dangerous factor of the grave asthma, we have assumed that you are not wrong.

The vegetable and the fruit repulse the cancer (the cancer)

The vegetable and the fruit repulse the cancer (the cancer)


 By the intake of the vegetable and the fruit, the various cancer (the cancer) three research which show the fact that risk decreases, the American cancer academic society which is held in Los Angeles (AACR) were reported with annual meeting.

 The american stand cancer laboratory (NCI) as for the research by Neal Freedman, targeting adult 490,802, the intake quantity of the fruit and the vegetable and those which compare the rate of occurrence of the head neck cancer. The fact that it was diagnosed the head neck cancer in 5 years was 787. Smoking and alcoholic intake dangerous factor (the risk factor) after the adjusting, concerning 1 day 1,000 caloric intake such as fruit or as for the person who 6 plates takes in the vegetable, head neck cancer risk 29% was low only 1.5 plates in comparison with the person who is not taken in, 1 plates just adds even could recognize 6% risk decrease. Independently you say that you could see the preventive effect where the vegetable is higher than the fruit.

 The american University of California Los Angeles (UCLA) the research group the broccoli and the soybean (the soy bean) the protein (the protein) due to reported the research result at laboratory level concerning the mechanism of the preventive effect for the breast cancer and the ovarian cancer. When the broccoli is digested, when [jiindorirumetan] (DIM) with the substance which is said is digested, the soybean, the substance, [genisutein] is formed. This time, these substances, operated the maneuverability of the cell of the breast cancer and the ovarian cancer, it was found that spread of the cancer is controlled. But, in the soybean the estrogen way because there is action, the person who has the cancer which is promoted by the estrogen says that note is necessary.

 The research group of American Hawaiian cancer research center targeting 180,000 3,518 people of California and the Hawaiian residence compared the intake quantity and cancer risk. As for, the onion and the apple, the substance which very is included in type, the kale and the broccoli etc. Besides the fact that with the person where the intake quantity is highest cancer risk 23% low thing it was understood, with the smoker furthermore the effect is large, as for the person where the intake quantity is high cancer risk was ascertained 59% low thing.

 When you can say, that it is best to cancer prevention to take in the plant characteristic food of various types from 3 research above, the American cancer research association (AICR) Melanie Polk has expressed. Besides the fact that it goes to the direct sales depot of the farmer, spends time at the foodstuff store and closely examines the vegetable, when also the device such that the cooking method which can eat the vegetable tastily is found it is necessary Polk calls.
