Scientists believe: violation of smell – a reliable harbinger soon death People who have difficulty distinguishing odors are not linger in this world. Usually die within the next five years. This, to say the least, gave an unexpected result research conducted at the University of Chicago (University of Chicago). For some reason, they lost their scent for a long time. Scientists examined 3,005 older Americans – men and women – aged from 57 to 85 years, working as part of a national project in the field of Health (National Social Life, Health and Aging Project). IN among others, subjects were tested for smell. Should be distinguish and name five fragrances that exuded special sticks resembling felt-tip pens. They smelled like mint, fish, orange, rose and skin. Photos from open sources
Three-quarters of the examined had a good sense of smell. They are correctly recognized smells: 46 percent – five out of five smells, 29 percent – four out of five. This is considered normal. About 20 percent found it difficult: they recognized two or three out of five smells. it average rate. About 4 percent barely recognized one. AND slightly more than a percent of the examined did not smell anything. At these are serious problems with smell. Professor Jayant Pinto with smelling “felt-tip pen.” Scientists have tested the sense of smell in the elderly. people. Tests were conducted in 2006. In 2011, scientists again appealed to their participants. By this time, that is, in five years, 430 people died. And it turned out that the maximum loss, not depending on age, suffered in those whose sense of smell was serious broken. This “problem group” missed 39 percent its members. For comparison, among people with average death rates claimed 19 percent, and among those who had normal sense of smell, only 10 percent died. – Of course, herself loss of smell alone does not lead to death, says Research Director Professor Jayant M. Pinto), but signals its approach, indicating that that something went wrong in the body. What exactly went wrong scientists have not yet clarified. But it is believed that the loss of smell is somehow is associated with stem cell activity – indicates their deficit. And it leads to the fact that the body loses its ability to self healing. This ends in death. AND AT THIS TIME Life expectancy seems really limited It is completely possible that the hypothesis of scientists about the role of stem cells in life extension, and therefore, in its accelerated folding, true. This conclusion is prompted by studies by scientists from the United States and Holland, a large group of whom recently analyzed the genome blood cells of one of the oldest women on Earth – Dutch Hendrikje van Andel-Schipper. She lived 115 years. Madame van Andel-Schipper was born in 1890. She died in 2005 in a dream, with a clear mind. Autopsy showed that in her brain there were no hints of typical senile ailments – Alzheimer’s and Parkinson’s. With this phenomenon, doctors pushed for the first time. A few days before her death the old woman turned to the director of the shelter in which she lived, with the words: “Well, here you, but the lord above said it was time for me to leave. “And she left, bequeathing his body to physicians to be examined as they as he pleases. And published the results. Photos from open sources
So scientists have looked at the blood of a long-lived woman with the intention to determine how 115 years influenced her – blood. Decryption genome showed :: at the time of death, the old woman’s blood consisted of cells produced by just two active stem cells – the so-called hematopoietic. Although usually they create blood approximately 1000 such cells. In other words, stock stem hematopoietic cells are exhausted. Blood essentially stopped be updated. The centenarian somehow felt this. AND climbed up. Ms. van Andel-Schipper lost her 115 years almost all of their stem cells. As scientists explain, man born with approximately 20 thousand hematopoietic stem cells. They are in the bone marrow, have the ability Intensively sharing, turning into all kinds of blood cells. Thanks to which the blood is renewed. Over the years the ability to stem cell division weakens. Each division shortens tips of chromosomes – the so-called telomeres. Until they barely noticeable. Steadily shortening telomeres – underreplication, to put it scientifically, it’s most likely aging. To death. Pity that the scientists were not interested in the long-lived woman, as in her sense of smell. Suddenly, it was also violated, and just because of the lack of stem cells.
