The degeneration of the brain related fear of air pollution and dust harmful: may cause Alzheimer’s disease data figure: local time on March 15, 2016, Mexico serious air pollution in Mexico City. Mexico City government ordered traffic control, it is recommended to minimize residents out. Mexico releases second first level ozone alert for the first time in 13 years. In September 12, according to foreign media reports, the material dust can lead to lung cancer, respiratory system disease, who believes that the global air pollution has caused the number of premature deaths accounted for 6.7% of the total number of deaths. Nowadays, people suspected of dust material will cause more harm to the human body, it may lead to Alzheimer’s disease. The research team from the UK, Mexico and the United States experts found that dust, harmful substances in the air inhaled will reach and remain in the brain. Study leader Maher (Barbara Maher), she led the team found that the link between the particles and the increase in Alzheimer’s disease. A study of brain samples from 37 people with neurodegenerative diseases, who lived in Mexico City or Manchester. In all the samples, iron oxide particles were found by experts, the researchers wrote in the report. There is a correlation between the activity of superoxide and Alzheimer’s disease and other neurodegenerative diseases." Iron oxide particles and iron oxide particles of dust grains in the brain samples with the external characteristics and composition of the same. Experts believe that these particles do not belong to the brain tissue, but from the external environment. Scientists estimate that particles with a diameter of about 150 nm can enter the brain through the nostril. They pointed out that the heritability of Alzheimer’s disease is less than 5%, therefore, environmental factors may be the main cause of the disease. Helmholtz of the Munich Research Center (Kreyling) said the results were "very important."". He pointed out that, especially iron oxide from Mexico City brain samples in very likely "is from the air, dust particles into the brain. Whether the dust particles of these dangerous residues in the brain, people now doubt the deeper layer. Whether they are one of the causes of Alzheimer’s disease remains to be investigated. The report, published by scientists, is only to clarify and infer, but also lack the necessary medical evidence.相关的主题文章:
