| 1 | Biallelic mutations in CDC20 cause female infertility characterized by abnormalities in oocyte maturation and early embryonic development显示文摘Dear Editor,Previously,the Mendelian phe no types in huma n oocyte maturation arrest,fertilization failure and early embryonic arrest,are largely underestimated.In recent years,'missing'Men delian phe no types and genes in these processes are beginning to be uncovered by us and others(Huang et al.,2014;Alazami et al..2015;Feng et al.,2016;Xu et al.,2016;Chen et al.,2017;Sang et al.,2019).However,the genetic basis for majority of patients resulting from abnormalities in these phe no types remains to be elucidated. | Lin Zhao Songguo Xue Zhongyuan Yao Juanzi Shi Biaobang Chen Ling Wu Lihua Sun Yao Xu Zheng Yan Bin Li Xiaoyan Mao Jing Fu Zhihua Zhang Jian Mu Wenjing Wang Jing Du Shuai Liu Jie Dong Weijie Wang Qiaoli Li Lin He Li Jin Xiaozhen Liang Yanping Kuang Xiaoxi Sun Lei Wang Qing Sang | 2020 | Protein & Cell2020，11，12： | 10 |
| 2 | Genetic variation within and among range-wide populations of three ecotypes of the Japanese grenadier anchovy Coilia nasus with implications to its conservation and management显示文摘Studies of range-wide populations can contribute to the comprehension of the relative roles of historical events and contemporary factors that influence genetic variation within and among populations.Japanese grenadier anchovy,Coilia nasus,is a commercially important fish,which widely distributes in the Changjiang River,the coasts of China and Korea,and the Ariake Sea of Japan.This species exhibits three life-history strategies(anadromous,landlocked and freshwater resident forms).Using two fragments of nuclear DNA,genetic variation within and among 18 populations across the rivers and coast of China and Ariake Sea of Japan was examined.Patterns of genetic diversity and divergence among populations varied widely across C.nasus'range,and indicated the different effects of historical events and anthropogenic factors.Strong genetic divergence between freshwater resident populations and other populations suggested that historical geographical factors greatly influenced the genetic structure of C.nasus.Significant genetic differentiation observed among lakes in lower Changjiang River and Huaihe River might be probably influenced by hydraulic facilities.The population genetic structure among the three ecotypes revealed in the present study indicated an important role for environment variation,and the factors responsible for shaping C.nasus different life history strategies might also impact population structure. | XUE Dongxiu YANG Qiaoli ZONG Shaobing GAO Tianxiang LIU Jinxian | 2020 | Journal of Oceanology and Limnology2020，38，3： | 1 |
| 3 | Dynamic changes in physicochemical property,biogenic amines content and microbial diversity during the fermentation of Sanchuan ham显示文摘Sanchuan ham is appreciated in Yunnan Province,China,for its characteristic flavor and taste,while the microbial community structure and biogenic amines content remain unclear during fermentation processes.In this study,we explored the physicochemical property,biogenic amines concentration and microbial diversity of external and internal Sanchuan ham by high-throughput sequencing during the processing of Sanchuan ham.Results showed that the nitrite remained at a stable level of 0.15 mg/kg which was significantly lower than the national health standard safety level of 20 mg/kg.In addition,compared with fresh hams,the content of total free amino acids in ripe Sanchuan ham has grown 14 folds;sour and bitter were the main tastes of Sanchuan ham.Notably,the concentration of cadaverine was the highest of all biogenic amines during the entire fermentation period.At the bacterial phyla level,Firmicutes and Actinobacteria were the two main phyla,while at the genus level,Staphylococcus was a significant strain throughout the whole fermentation.Moreover,the dry stage has a great impact on the succession change of microbial community structure.Simultaneously,the change trends and composition of bacteria in the interior have slight discrepancies with those of the exterior of Sanchuan ham. | Zhongai Chen Hong Chen Huan Du Cong Chen Kaixiang Lu Qiaoli Xue Yongjin Hu | 2024 | Food Science and Human Wellness2024，13，1： | 0 |
