[quick news] on November 21, 2018, Chinese scientists first revealed the whole process of in vivo homing of new hematopoietic stem cells

For the first time, Chinese scientists have revealed the whole process of in vivo homing of new hematopoietic stem cells Under the leadership of research team led by Pan Weijun, researcher of Shanghai Institute of nutrition and health, Chinese Academy of Sciences, the complete dynamic process of in vivo homing of hematopoietic stem cells has been analyzed with high clarity for the first time in the world The research results have been published online in Nature journal recently Pan Weijun led his team for six years On the basis of optimizing in vivo imaging technology, he further integrated in vivo immunofluorescence labeling, genetic regulation and graphic reconstruction calculation, and created a new research system that can completely analyze the whole process of homing of hematopoietic stem cells in vivo The team took the lead in establishing a hematopoietic stem cell labeling system with Chromotropic fluorescent protein, and established a long-term in vivo observation and tracking scheme for hematopoietic stem cells under a high-resolution confocal fluorescence microscope, which vividly presented the whole process of hematopoietic stem cells from birth to homing from macro to micro Https:// "super magnesium" may be the next miracle material for outdoor equipment In the manufacturing of outdoor equipment or bicycle products, carbon fiber has been used as the main material for a long time, because of its advantages of light weight, high strength, corrosion resistance and so on It is used to make bicycle frame and wheel hub, ski pole, camping chair and even tent pile But the disadvantage of carbon fiber is the high cost of production, which usually makes the product expensive Now allite, a company, has found that "super magnesium" can be an alternative to carbon fiber, showing the same level of performance as carbon fiber materials, at the same time being cheaper and more environmentally friendly Https:// engineers developed the "invisible" air filter nasal plug Us engineers developed an air filter nasal plug, which can block 90% of the large pollution particles and 70% of the fine particles from entering the lungs, and also can block the hypersensitive sources and bacteria The filter uses static electricity to capture air particles for 12 hours The filter, made of transparent material, looks better and is more comfortable to use than a mask, but it doesn't stop pollutants from entering the lungs through the mouth The new air filter snuff, 10 in a bag, costs $13 Will it be a new choice for people to deal with air pollution? Https:// one belt, one road, the food education and technology alliance of universities, the establishment of food problem is the common challenge faced by the international community Recently, the first one in the world, one of the "one belt, one road" food education technology alliance in Wuxi was founded In recent years, the production pattern of global food industry has changed significantly, showing a typical multipolar development trend One belt, one road, along the border, is facing new opportunities and challenges in the food industry, food science and food education and technology in universities It also indicates that it is imperative to build a high-level international and innovative talent system, promote food science development and upgrade food industry along the line According to Professor Chen Jian, academician of the Chinese Academy of engineering and President of Jiangnan University, the alliance was initiated by Jiangnan University, and 39 universities from 27 countries responded and actively participated in it, and reached a consensus on cooperation and exchange Http://digitalpaper.stdaily.com/http_ / 21 / content_ HTM?
