The latest medical discoveries

A recent scientific study on a new method for the treatment of diabetes, and that by planting insulin-producing cells in the body of the patient. She said the study by scientists at Harvard University, it has become possible to produce quantities of pancreatic cells by industrial bioreactors, then implanted in the body of the patient to ensure that exposed to a preventive attack. This study came after the experiment conducted by the researchers on a group of mice infected with diabetes, and were able, during which hundreds of millions of human pancreatic cells producing insulin. The study pointed out that this could be a treatment for children who suffer from diabetes type force them to daily doses of insulin to compensate for the shortfall in the level of glucose in their blood. Professor of Medicine at the University of London and Chris Mason described the study as "an enormous scientific progress," adding that it may lead to the production of large-scale cells for the treatment of all types of diabetes. Scientists hope that this discovery constitutes not only on the type of diabetes, which affects children's disease, but the type suffered by the elderly is also a new 

 

 

 

Scientists could culturing muscles industry taken from the original muscle cells and make them grow in a research laboratory. And it is currently being tested for the replacement of the affected muscles, after confirming overcome toxicity and effectiveness tests. According to the site «Quartz» the scientists in biomedical engineering at the American Duke University were able to isolate stem cells from the muscles of Virat, and then grown in a separate muscle fibers. According to lead researcher permit, Nenad Baursak, the site «Quartz», the researchers were able to get strong muscles grown within the laboratory are similar strength in the bodies of mice. Nenad points out that muscle cultured enjoying a very important advantage is that they can cure itself by itself when torn or exposure to infection, and that by rebuilding the lost tissue. The researchers said that these muscles are ten times stronger than any previously muscles were cultured in laboratories. And despite the fact that these tests finally revealed by using experiments in mice, however, the team of researchers, headed by Nenad began in successful experiments on human muscles as well. According to the research team, the replacement of the original laboratory-cultured muscle muscle replace the doctors need to take muscle tissue from the body of the patient and the cultivation of stem cells, including for new tissue, and then returned to the patient's body again. When asked about the availability of this technology soon, scientists said that it is important to first find out how you can get more of the stem cells of the human body, as we can now get a lot of them, but lose their effectiveness later. The researchers need to solve the problem of feeding the muscles in the laboratory with blood, and ensure the continuity of the flow of blood to the muscles to grow larger. As the largest breeding any part of one millimeter requires an innovative technology for it. The researchers say that overcome these challenges, manufacturers will make these muscles laboratory ready for use with humans as of now. But at the moment it is expected to wait 10 to 15 years to overcome these challenges.

 

New medical accomplish successful in the field of heart disease, as it enables surgeons Chekeon for the first time to perform heart surgery without the need for a chest incision and is difficult to avoid the risk of the consequences of the surgery, which is associated with each process. This medical procedure that description Palmmaz and rare on the work of a small incision in the left side of the rib cage, and pass the device such as the anchor to the ventricle gradually to isolate damaged from that sound in the heart muscle parts, in conjunction with a machine outside the body to monitor all the indicators and the movement of the heart muscle during the process. He says doctors at Drexel University Czech This action reduces the complications that are sometimes fatal, especially for patients with deficiencies or failure of the heart muscle, which is being local anesthesia to monitor any development gets at the same time ensure its success. Professor of cardiac surgery at the University Andrew Vheslr "and said this is the first time you do this type of surgery .. It's easy and guaranteed and there is no side effects such as those usually associated with traditional surgical procedures." Physicians are expected to become available this way in the world to promote the work of the heart muscle, especially with the increasing heart disease which is the direct cause of the high level of deaths around the world.

 

Invented a new way to test blood does not rely on acupuncture scientists, and through the method relies on measuring the degree of blood temperature, and better knowledge level, through electronic chips placed on the skin. And it became a doctor can check the patient's blood without even follow the traditional method of acupuncture, through the development of small electronic chips in about five areas of the body. The doctors and researchers working at a hospital in Barcelona, ​​Spain, on workout this kind of medical examinations across slides to monitor blood sugar levels in which, for example. This method was used the first time by the Russian astronauts in early 1990 and was limited to use and the results are not identical with the traditional blood test. As it has been previously used in China and countries in Eastern Europe such as Germany and Austria have shown impressive results, but later researchers have developed to give high accuracy in the results. The doctor said Antonio Sekas: "These chips reveal temperature through regular mechanisms in the body, these chips should be placed on the index finger and the underarms and the points that show the navel Bodh bicycle body temperature of what we can measure blood levels and standards." It is worth mentioning that this method can not be used to detect specific diseases such as hepatitis and AIDS because the device has not been completed yet been programmed to detect such diseases

In a move that may be considered a breach prominent in the field of regenerative medicine, US experts were able to "produce" human lung within the scientific laboratory, in scientific progress might take to apply to the reality of the ground for some time. She described Joan Nichols, a researcher at the "University of Texas Medical Branch," achievement as a "move from science fiction towards scientific facts hand." And about the process of "production", the researchers unloading lung and one of the two, two children died as a result of shock, cities hit seriously what prevented their use in the cultivation of the members of the process, to preserve the exterior side of the protein collagen and elastin fibers, then pumped other lung cells inside, before flooding fluid helps in providing the necessary nutrition for the growth of cells, according to Nichols. And a full grown human lung after four weeks of the operation, which has been replicated, to cultivate other new lung lungs of deceased children. Nichols explained that the lung "cultivated" completely natural-like, pointing out that it may be used in organ transplant surgery probably within 12 years. Said Stephen Badelak, deputy director of "McGowan Institute for Regenerative Medicine" at the University of Bazbrah, that the new achievement may be a solution to the lack of donors of human organs.

 

British researchers said that a simple examination of the Games is able to detect teenagers at risk of depression. He explained researcher Ian Goodyear of the University of Cambridge that teens who saliva test shows they have a rise in cortisol level caller tension and show symptoms of minor depression, with 14 times more vulnerable to depression than others. Goodyear explained in the study published in the journal «Brosidang Of National Academy of Science» saying: «This test will help us to target individuals at depression and will help in reducing the risk of contracting severe cases of depression and its consequences for adult life». The study was based on saliva samples to hundreds of teenagers as well as information about themselves talked about symptoms of depression feel it. It was interesting that the girls who showed up in the examination of saliva cortisol and symptoms of depression were more likely to have increased by four times to injury severe depression, a rise of more than 14 percent for boys, it refers to the difference between the sexes.

 

Scientists from Europe said they have developed industrial hand of a new kind of return to its owner the ability to touch things and detection. According to a statement issued by the University of Lausanne Applied Swiss today (February 5, 2014), the Danish citizen Apo Dennis Sorensen was the first person in the world try this alternative hand and regain the ability to sense things. And about that experience, Sorensen stressed that when holding something that was hand industrial feel if this thing is solid or soft, round or polygon. The Sorensen, aged 36 years, had lost his left hand about nine years ago in an accident because of fireworks. Through Danish citizen admiration of this new industrial hand. And participated in the development of this industrial hand many European universities and hospitals. And allocated Medical Journal magazine "Science Medicine Transleychunal" Today a special issue about good invention, which researchers Supervisors talked about it at length in the mentioned magazine
