[quick news] on June 24, 2019, the Journal Citation Report of 2019 by Kerui Wei'an reveals the influence of academic journals

Recently, the web of science group released the Journal Citation Report 2019 (JCR), It provides a complete index of 3 million articles, reviews and other source journals, including 11877 journals from 81 countries and regions, and publishes data, indicators and analysis independent of journal publishing institutions for global high-quality academic journals This year's report covers 236 subjects, including three newly included subjects: Quantum Science and technology, development research and regional and urban planning For journals with abnormal citation, such as excessive self citation and mutual citation, JCR will be eliminated This year, 17 journals (accounting for 0.14% of the selected journals) were warned by JCR to ensure the fairness and fairness of the report For publishers, libraries, funding institutions and scientific research institutions, the citation data and influence indicators included in JCR can be regarded as an important resource: publishers can make use of JCR Understand the actual performance of its journals, and make benchmarking analysis of its own journals with reference to other journals of its discipline; the library can use this report to understand which journals are most important to the work and success of its institutions and researchers, and which journals are worth subscribing to; scientific research institutions can make JCR As a clear directory and guide, we can explore and select the most suitable platform for publishing research results Http://news.scienceet.cn/htmlnews/2019/6/427642.shtm "I have horns on my head!" The "little secret" from ruminants: why do cattle, sheep and deer have horns? What are the genetic differences between the horns of cattle, sheep and deer? Recently, Professor Jiang Yu's research team from the school of animal science and technology, northwest agricultural and Forestry University of science and technology and 9 domestic and foreign units such as Northwest University of technology published the research paper "genetic basis for the occurrence and development of ruminant horn and the rapid regeneration of antler" in science online By comparing different types of ruminant genomes and up to 270 transcriptome, the researchers found that there are similar gene expression patterns in Cornu and antler, and the genes with specific high expression mainly come from the genes expressed in bone, skin, brain and testis These horn tissue-specific high expression genes, together with some rapid evolution genes, are involved in the migration pathway of neural spinal cells Therefore, it is proposed for the first time that the horns of ruminants have the same cell origin -- head neural spinal stem cells, which provides genetic evidence for the single evolutionary origin of ruminant horns, and also provides theoretical basis for breeding hornless cattle and sheep It provides a key target gene for the production of hornless cattle and sheep by gene editing Https://science.sciencemag.org/content/364/6446/eaav6335 has solved the regional mystery of nasopharyngeal carcinoma Nasopharyngeal carcinoma has a significant geographical distribution in geographical distribution Nasopharyngeal carcinoma is rare in most parts of Europe and Africa However, the incidence rate of nasopharyngeal carcinoma is significantly higher in Southeast Asia and Southern China, China China incidence rate of nasopharyngeal carcinoma in Guangdong is 20 times that of other low incidence rate areas Therefore, NPC is also known as "Guangdong cancer", which seriously affects the life and health of people in South China Recently, Zeng Yixin, academician of cancer prevention and treatment center of Sun Yat sen University, Professor Zhai Weiwei, research group of Liu Jianjun, Singapore Institute of genetics and Institute of zoology, Chinese Academy of Sciences, found that the occurrence of NPC was related to the high-risk subtype of EB virus in the region, balf2 Φ CCT subtype or the high-risk subtype of EB virus that caused the high incidence of NPC The related research results were recently published in the journal Nature Genetics In order to make NPC a preventable disease, the cancer prevention and treatment center of Sun Yat sen University is gathering the research team and strength of genetics, molecular medicine, epidemiology and vaccine to develop EB virus vaccine Researchers hope to block the risk of subtype infection by EB vaccine, reduce the risk of nasopharyngeal carcinoma caused by high risk subtypes, reduce the incidence rate, achieve primary prevention of nasopharyngeal carcinoma, and snipe Guangdong cancer Https://www.nature.com/articles/s41588-019-0436-5 Chinese researchers found the "killer" of cadmium enrichment in Rice He Zhenyan, associate researcher of Institute of Botany, Chinese Academy of Sciences, worked with the team of China Agricultural University to identify an active transporter involved in cadmium in rice through genome-wide association analysis technology and gene function verification system, and revealed the molecular mechanism of the difference in cadmium accumulation between Indica and japonica rice, providing reference for the cultivation of low cadmium rice varieties 。 Relevant achievements were published in the international academic journal Nature · communication The researchers identified a secondary active transport protein of cadmium in rice, which was mainly expressed on the plasma membrane of rice root and participated in the process of cadmium absorption in rice root and cadmium accumulation in rice grain The lack of this protein can significantly reduce the cadmium absorption efficiency and cadmium accumulation in rice grain The researchers further found that the genotypes of Indica and japonica rice showed significant differentiation The results of field experiments showed that the content of Cd in the grains of the near isogenic lines containing the japonica rice genotype could be significantly reduced after it was introduced into the indica rice The results showed that the genotype had great potential in the breeding of low cadmium indica rice Https://www.nature.com/articles/s41467-019-10544-y the research team led by Pei duanqing, researcher of Guangzhou Institute of biomedicine and health, Chinese Academy of Sciences, who developed "5g" version of somatic reprogramming technology, used 7 factors to replace the traditional 4 factors (oksm) and developed a new and efficient reprogramming method This method is similar to the mobile communication signal upgrading from "4G" to "5g", which provides high-quality cell sources and new cell models for regenerative medicine and mechanism research of induced pluripotent stem cells The related research was published online recently in cell · report This study reveals that the reprogramming factor combination designed according to the dynamic changes of chromatin plays an important role in determining the characteristics of iPSCs, which is conducive to the rapid acquisition of high-quality iPSCs and provides more options for further revealing reprogramming mechanism At the same time, short-term and rapid access to high-quality iPSCs can shorten the process of cell therapy and accelerate the development of stem cells and regenerative medicine into clinical practice https://www.cell.com/cell-reports/fulltext/S2211-1247(19)30697-7
