1The Genome of Medicinal Plant Macleaya cordata Provides New Insights into Benzylisoquinoline Alkaloids Metabolism显示文摘在动物农业和药的抗菌素的 overuse 引起了一系列潜在的威胁到公共健康。Macleaya cordata 是从 Papaveraceae 家庭的药用的植物种,提供为抗菌剂的制造的一个安全资源为家畜喂添加剂。从 M. 的活跃成分 ? cordata 被知道包括 benzylisoquinoline 碱(偏爱) 象 sanguinarine (圣) 和 chelerythrine (CHE ) 那样的 ?,而是他们的新陈代谢的小径还得在这非模型植物被学习。在 M. 的圣和 CHE 的活跃生合成 ? cordata 被喂 13标记 C 的酷氨酸。为了增加,推进卓见,我们 de novo 定序 M 的整个染色体。cordata,第一从 Papaveraceae 家庭被定序。M.? 盖住 378 Mb 的 cordata 染色体与 43.5%being 编码 22,328 预言的编码蛋白质的基因 transposable 元素。作为基础 eudicot 的一个成员, M.? cordata 染色体缺乏 ? 发生在几乎所有 eudicots 的 paleohexaploidy 事件。从 genomics 数据, 16 的一个完全的集合 ? 新陈代谢 ? 为圣和 CHE 生合成的基因被检索,并且 14 项他们的生物化学的活动被验证。这些 genomics 和新陈代谢的数据在 M. 显示出保存 BIA 新陈代谢的小径 ? cordata 并且由庄稼改进或微生物引起的小径重建为圣和 CHE 的未来生产提供知识基础。Xiubin Liu Yisong Liu Peng Huang Yongshuo Ma Zhixing Qing Qi Tang Huifen Cao Pi Cheng Yajie Zheng Zejun Yuan Yuan Zhou Jinfeng Liu Zhaoshan Tang Yixiu Zhuo Yancong Zhang Linlan Yu Jialu Huang Peng Yang Qiong Peng dinbo Zhang Wenkai Jiang Zhonghua Zhang Kui Lin Dae-Kyun Ro Xiaoya Chen Xingyao Xiong Yi Shang Sanwen Huang Jianguo Zeng 2017Molecular Plant2017,10,7:19
2The chromosome-level Hemerocallis citrina Borani genome provides new insights into the rutin biosynthesis and the lack of colchicine显示文摘Hemerocallis citrina Borani(huang hua cai in Chinese)is an important horticultural crop whose flower buds are widely consumed as a delicious vegetable in Asia.Here we assembled a high-quality reference genome of H.citrina using single-molecule sequencing and Hi-C technologies.The genome assembly was 3.77 Gb and consisted of 3183 contigs with a contig N50 of 2.09 Mb,which were further clustered into 11 pseudochromosomes.A larger portion(3.25 Gb or 86.20%)was annotated as a repetitive content and 54,295 protein-coding genes were annotated in the genome.Genome evolution analysis showed that H.citrina experienced a recent whole-genome duplication(WGD)event at~15.73 million years ago(Mya),which was the main factor leading to many multiple copies of orthologous genes.We used this reference genome to predict 20 genes involved in the rutin biosynthesis pathway.Moreover,our metabolomics data revealed neither colchicine nor its precursors in H.citrina,challenging the long-standing belief that this alkaloid causes poisoning by the plant.The results of our disruptive research are further substantiated by our genomic finding that H.citrina does not contain any genes involved in colchicine biosynthesis.The high-quality genome lays a solid foundation for genetic research and molecular breeding of H.citrina.Zhixing Qing Jinghong Liu Xinxin Yi Xiubin Liu Guoan Hu Jia Lao Wei He Zihui Yang Xiaoyan Zou Mengshan Sun Peng Huang Jianguo Zeng 2021Horticulture Research2021,8,1:6
3Dynamic Changes of ORF1ab and N Gene Ct Values in COVID-19 Omicron Inpatients of Different Age Groups—Beijing Municipality,China,November-December 2022显示文摘Introduction:In November 2021,the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron variant was identified as the variant of concern and has since spread globally,replacing other cocirculating variants.To better understand the dynamic changes in viral load over time and the natural history of the virus infection,we analyzed the expression of the open reading frames 1ab(ORF1ab)and nucleocapsid(N)genes in patients infected with Omicron.Methods:We included patients initially admitted to the hospital for SARS-CoV-2 infection between November 5 and December 25,2022.We collected daily oropharyngeal swabs for quantitative reverse transcriptase-polymerase chain reaction tests using commercial kits.We depicted the cycle threshold(Ct)values for amplification of ORF1ab and N genes from individual patients in age-specific groups in a time series.Results:A total of 480 inpatients were included in the study,with a median age of 59 years(interquartile range,42 to 78;range,16 to 106).In the<45-year-old age group,the Ct values for ORF1ab and N gene amplification remained below 35 for 9.0 and 11.5 days,respectively.In the≥80-year-old age group,the Ct values for ORF1ab and N genes stayed below 35 for 11.5 and 15.0 days,respectively,which was the longest among all age groups.The Ct values for N gene amplification took longer to rise above 35 than those for ORF1ab gene amplification.Conclusion:The time to test negative varied among different age groups,with viral nucleic acid shedding taking longer in older age groups compared to younger age groups.As a result,the time to resolution of Omicron infection increased with increasing age.Qing Zhang Zhaomin Feng Yiwei Hao Lirong Wei Aibin Wang Zhixing Han Meimei Tian Sheng Sun Xin'gang Li Tianjiao Xue Xiangjing Kong Baoliang Li Cheng Kou Quanyi Wang Da Huo Linghang Wang 2023China CDC weekly2023,5,8:0
4Expert recommendations on data collection and annotation of two dimensional ultrasound images in azoospermic males for evaluation of testicular spermatogenic function in intelligent medicine显示文摘Testicular two-dimensional ultrasound is a testing modality that is often used to evaluate azoospermia and other related diseases.With the continuous development of deep learning in recent years,the combination of deep learning and testicular ultrasound appears unstoppable despite a lack of relevant standards.One of the major problems associated with the digitization of ultrasound images is the uneven quality of data however,and a standardized data source and acquisition process has not yet been developed.Such a standard could fill the current gap,and establish acquisition criteria for ultrasound images of testes during the male reproductive period,including grayscale ultrasound,shear wave elastography,and contrast-enhanced ultrasound.By following these guidelines the quality of testicular ultrasound images would be improved and standardized,which would lay a solid foundation for the standardization of testicular ultrasound images,and assist automated evaluation of testicular spermatogenic function of whole testis in azoospermic males.Wanling Huang Yifan Xiang Yahan Yang Qing Tang Guangjian Liu Hong Yang Erjiao Xu Huitong Lin Zhixing Zhang Zhe Ma Zhendong Li Ruiyang Li Anqi Yan Haotian Lin Zhu Wang Chinese Association of Artificial Intelligence Medical Artificial Intelligence Branch of the Guangdong Medical Association 2022Intelligent Medicine2022,2,2:0
