[quick news] on September 4, 2018, the elderly who adhere to the "Mediterranean diet" can extend their life span

People aged 65 or over can live longer if they stick to the Mediterranean diet, which is rich in fish, nuts and fresh vegetables, not only good for the health of the elderly, but also reduce the risk of death, according to the guardian Those closest to the "Mediterranean diet" are also more likely to do more physical activity in their spare time, according to the study In addition, the researchers say the benefits of a healthy lifestyle from a young age may be greater Https://www.theguardian.com/science/2018/aug/31/mediterranean-die-old-age-long-life-study researchers from Japan Institute of science and chemistry and Queensland University of technology in Australia found that chrm1 and chrm3 were found by knocking out the genes in mice and observing their sleep These two genes control shallow sleep and dreaming After knockout of these two genes, the experimental rats did not produce shallow sleep, only waking and deep sleep The daily time of shallow sleep in the experimental rats decreased from about 70 minutes to almost zero Mice without sleep did not dream, and memory declined, but the researchers said it was not enough to affect the survival of the mice The researchers say it is the first time that scientists have discovered a gene that determines whether there is shallow sleep or not, and it is also the first time to confirm that animals can have no shallow sleep or not This research result will be helpful to study the cause of sleep disorder and develop the treatment Https://www.cell.com/cell-reports/fulltext/s2211-1247 (18) 31200-2 ා India's fight against predatory journals predatory journals became a problem because research funding was wasted on fraudulent publishers who would not live up to their promises According to a large-scale international journal survey published in various media in July, the number of papers published by five major predatory publishers has tripled since 2013, to about 175000 India is the base of many publishers who host suspected predatory journals At the same time, a number of studies have found that a large part of articles in such journals come from scholars in the country Many Indian scholars attribute this situation to problems in the country's system of assessing academic achievements In 2010, UGC, a higher education regulatory and funding institution in India, introduced a system to assess academic level The system is called academic achievement index, which puts a considerable proportion on the number of research publications Colleges and universities must use this indicator to hire and promote staff But scientists complain that this has encouraged academia and universities to focus on the number of publications rather than the quality Http://news.scienceet.cn/sbhtmlnews/2018/9/338768.shtm Russian and American made accelerator for cancer treatment, budkol Institute of nuclear physics, Siberia branch of Russian Academy of Sciences, together with American three alpha energy company, will make boron neutron capture accelerator for cancer treatment in China Boron neutron capture therapy is a method of selective elimination of malignant tumor cells: first, inject a special compound containing boron into the patient's vein, which has a strong affinity with cancer cells; then, irradiate with neutron rays, the neutron reacts with the boron entering the cancer cells strongly, and release a highly destructive ray to kill the cancer cells According to the director of Neurosurgery at Tsukuba University in Japan, the treatment developed by Russian physicists has a good prospect On the whole, boron neutron capture therapy has a significant effect in the treatment of complex and serious cancer Http://sputniknews.cn/science/201808311026249961/novartis car-t therapy kymriah was approved in Europe Novartis won approval for car-t therapy kymriah in Europe However, according to the payment details and production capacity formulated by Novartis, the marketing situation of this blood tumor drug in EU countries is different The company initially planned to use the drug in Europe for patients under 25 years old with B-cell acute lymphoblastic leukemia (all), and later for adults with diffuse large B-cell lymphoma (DLBCL) This one-off therapy works by removing and modifying the T cells of individual patients to attack cancer and then re delivering them into the body It has been approved for two indications in the United States In the United States, it costs US $475000 for B-cell acute lymphoblastic leukemia and US $475000 for diffuse large B-cell acute lymphoblastic leukemia The cost of cell lymphoma is $373000 The treatment is intended for patients who are no longer able to use other drugs http://yao.dxy.cn/article/577594
