    With his daughter, he took the entrance examination first At the recent graduation ceremony of central China Normal University, Hunan's 55 year old "Xueba mother" graduated Zhou Yasong, a master of vocal music major, became popular on the Internet after 60 years Three years ago, she and her daughter took the postgraduate entrance examination together She became a "sister mother" one year earlier than her daughter, and successfully graduated on June 20 this year Zhou Yasong, who used to work in the archives management of a local authority, only had a high school degree, and then obtained a bachelor's degree through correspondence and self-examination Now, after three years of hard work, Zhou Yasong has become a master's degree graduate of vocal music major of Huazhong Normal University At the graduation ceremony, Zhao Lingyun, President of Huazhong Normal University, told the story of Zhou Yasong's mother and daughter, saying that Zhou Yasong vividly demonstrated the truth of "endless learning" with his own practice, proving that there has never been a time and age limit for learning Zhou Yasong's study experience won the applause of all the teachers and students HTTPS: / / baijiahao Baidu COM / S? Id = 163712063762355335 & Wfr = Spider & for = PC Zhao bingqiao, Professor of the State Key Laboratory of medical neurobiology and the Research Institute of brain science, Fudan University, joined hands with Zhong Kai, team of the strong magnetic field science center of the Chinese Academy of Sciences, and made progress in the research on the pathogenesis of Alzheimer's disease The results were published online in the journal PLoS Biology The researchers demonstrated the role of vascular factors in the pathogenesis of Alzheimer's disease, and revealed that the gene "ADAMTS13" plays a key role in the pathogenesis of Alzheimer's disease by increasing the clearance of related blood-brain barrier In the future, Alzheimer's disease may be delayed It has been found that knockout of ADAMTS13 gene can cause the early destruction of the blood-brain barrier in Alzheimer's disease model mice, and with the increase of age, the destruction of the blood-brain barrier will further aggravate, resulting in the decrease of cerebral capillaries and cerebral blood flow, and eventually lead to the impairment of blood vessel clearance and memory of a β in the brain Increasing the content of ADAMTS13 in the brain of mice can improve the cognitive dysfunction of mice by protecting the brain barrier of hemorrhage, increasing the number of capillaries and cerebral blood flow, promoting the clearance of a β in the brain Https://journals.plos.org/plosbiology/article? Id = 10.1371/journal.pbio.3000313 vascular implant coating to achieve drug safety and slow release, Tomsk University of technology in Russia, in cooperation with international research teams from China, Germany and the UK, jointly developed a new vascular implant drug coating, which can safely release drugs to the human body The drug coating is a micro chamber system, which prevents restenosis or thrombosis of blood vessels The results were published in the European Journal of polymers "A model substance (Rhodamine B, a water-soluble fluorescent dye) was loaded into the microcavity with an efficiency of 76%, and the weight of each microcavity was 2.88 × 10-9 μ G Under laboratory conditions, the material in the micro chamber buffer was excreted for a total of 13 days at 37 ℃, thus preventing restenosis or thrombosis of blood vessels " One of the authors, Sergei tverdolhlebov, a researcher at the Russian wienberger Center for science and education, said that with the help of ultrasound, biodegradable micro chamber systems can accelerate drug release Similarly, smooth release of essential drugs can prevent restenosis or thrombosis The drug coating can also be used in coronary artery stents, which can achieve additional pharmacological effects Https://ා! A drug is expected to improve the growth rate of children with dwarfism, and the average growth rate of subjects will increase by 50% An international clinical trial led by the Murdoch children's Institute in Australia has shown that a drug that helps regulate bone development can significantly increase the growth rate of children with achondroplasia and is expected to make them grow higher According to the researchers, achondroplasia is caused by an overactive signal that blocks growth, and the drug vosoritide can inhibit this signal and promote bone development to return to normal In order to further understand the safety, tolerance and optimal dosage of the drug, the researchers selected 35 children aged 5 to 14 years old for clinical trials In a trial lasting more than four years, the children were divided into groups, who received subcutaneous injection every day in the first year, but the dosage was different The results showed that the average growth rate of the subjects increased by 50%, and the growth rate of the children who received specific doses of drugs was the fastest, and the growth rate was still several years after the drug was stopped All subjects had adverse reactions But according to the researchers, adverse drug reactions are mostly "mild." Https:// NASA will test "green fuel" in space for the first time According to the official website of the National Aeronautics and Space Administration (NASA), NASA will test a non-toxic rose colored liquid fuel and propulsion system in space for the first time, the "green propellant injection mission" (gpim )This month will help SpaceX's Falcon heavy rocket lift off, which is expected to power spacecraft to the moon or other celestial bodies in the future This high-performance fuel was developed by the Air Force Research Laboratory (AFRL) The propellant is a mixture of hydroxyl ammonium nitrate and oxidant After combustion, it will produce a substitute for hydrazine "There are two major benefits to using this fuel and propulsion," explains Christopher McLean, chief researcher at gpim First of all, the spacecraft can be refueled in the manufacturing process, so the launch process can be simplified, thus saving costs Another benefit is that the new fuel is thicker than hydrazine, with a performance improvement of nearly 50%, which means that spacecraft can work longer with less fuel " https://
