4相关性和一致性:这对相仿概念和测量方法的回顾与阐明(英文)显示文摘一致性(agreement)和相关性(correlation)是两个广泛使用的概念,用来评估变量之间的关联。虽然二者相似且相关,但是它们代表关联完全不同的概念。评估变量之间的一致性假设变量测量的是相同的结构,而在变量测量完全不同的结构时也可以评估它们之间的相关性。这种概念上的差异就要求使用不同的统计方法,并且当评估一致性或相关性时,统计方法根据数据的分布和研究者的兴趣可能会有所不同。例如,Pearson相关性,作为评估连续变量之间相关性的一种普遍测量方法,只有用于符合线性关系的变量时才能提供有用的信息;当用于不符合线性关系的变量时就无法提供准确信息甚至会产生误导。同样地,内部相关性,作为一种评估连续变量之间一致性的常用方法,如果一致性不好的实质正好是研究兴趣所在,那么该测量就不能为研究者提供充分的信息。本报告回顾了一致性和相关性的概念,并讨论了几种常用方法在应用中的差异。Liu JY Tang W Chen GQ Lu Y Feng CY Tu XM 2016上海精神医学2016,28,2:6
5Cell cycle-related kinase reprograms the liver immune microenvironment to promote cancer metastasis显示文摘The liver is an immunologically tolerant organ and a common metastatic site of multiple cancer types.Although a role for cancer cell invasion programs has been well characterized,whether and how liver-intrinsic factors drive metastatic spread is incompletely understood.Here,we show that aberrantly activated hepatocyte-intrinsic cell cycle-related kinase(CCRK)signaling in chronic liver diseases is critical for cancer metastasis by reprogramming an immunosuppressive microenvironment.Using an inducible liverspecific transgenic model,we found that CCRK overexpression dramatically increased both B16F10 melanoma and MC38 colorectal cancer(CRC)metastasis to the liver,which was highly infiltrated by polymorphonuclear-myeloid-derived suppressor cells(PMNMDSCs)and lacking natural killer T(NKT)cells.Depletion of PMN-MDSCs in CCRK transgenic mice restored NKT cell levels and their interferon gamma production and reduced liver metastasis to 2.7% and 0.7%(metastatic tumor weights)in the melanoma and CRC models,respectively.Mechanistically,CCRK activated nuclear factor-kappa B(NF-κB)signaling to increase the PMN-MDSC trafficking chemokine C-X-C motif ligand 1(CXCL1),which was positively correlated with liver-infiltrating PMN-MDSC levels in CCRK transgenic mice.Accordingly,CRC liver metastasis patients exhibited hyperaaivation of hepatic CCRK/NF-κB/CXCL1 signaling,which was associated with accumulation of PMN-MDSCs and paucity of NKT cells compared to healthy liver transplantation donors.In summary,this study demonstrates that immunosuppressive reprogramming by hepatic CCRK signaling undermines antimetastatic immunosurveillance.Our findings offer new mechanistic insights and therapeutic targets for liver metastasis intervention.Xuezhen Zeng Jingying Zhou Zhewen Xiong Hanyong Sun Weiqin Yang Myth T.S.Mok Jing Wang Jingqing Li Man Liu Wenshu Tang Yu Feng Hector Kwong-Sang W ang Shun-Wa Tsang King-Lau Chow Philip Chun Yeung John Wong Paul Bo-San Lai Anthony Wing-Hung Chan Ka Fai To Stephen Lam Chan Qiang Xia Jing Xue Xiao Chen Jun Yu Sui Peng Joseph Jao-Yiu Sung Ming Kuang Alfred Sze-Lok Cheng 2021Cellular & Molecular Immunology2021,18,4:5
6Variations in Wool Growth with Nutrient Supply in Northern China显示文摘Field studies on essessment of nutritional status of the grazing sheep were carried out in each of the three major grassland regions, the eastern Inner Mongolia and beyond grassland, the Inner Mongolia - Ningxia - Gansu grassland and the Xinjiang grassland, in northern China. The results obtained showed that the wool production of fine wool sheep in these regions varied between regions and seasons, with similar seasonal patterns in all regions and that reducing the seasonal variations in nutrient supply would enhance wool production substantially. Nutritional limitations to wool growth of the grazing sheep in these regions were suggested, those were: the shortage of protein supply in winter and early spring; the poor quality of much of the pasture and the hay used as supplements, the low energy intake during winter which probably necessitated the use of body stores to maintain body temperature.D X Lu,Iner(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)Z C Feng,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)H R Wang,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)R Z Yang,(Xinjiang Institute of Animal Science.Xinjiang Academy of Animal Science.Yiu Hou Road.Urumqi.Xinjiang Uygur Autonomous Region PRC)C T Ma,(Chinese Academy of Agricultural Sciences.Lanzhou.Gansu.PRC)D B Purser,(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)J R Lindsay(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)D W Peter(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014) 1997畜牧与饲料科学1997,22,S1:3
7Prolonged feeding with guanidinoacetate, a methyl group consumer, exacerbates ethanol-induced liver injury显示文摘AIM To investigate the hypothesis that exposure to guanidinoacetate(GAA, a potent methyl-group consumer) either alone or combined with ethanol intake for a prolonged period of time would cause more advanced liver pathology thus identifying methylation defects as the initiator and stimulator for progressive liver damage.METHODS Adult male Wistar rats were fed the control or ethanolLieber De Carli diet in the absence or presence of GAA supplementation. At the end of 6 wk of the feeding regimen, various biochemical and histological analyses were conducted. RESULTS Contrary to our expectations, we observed that GAA treatment alone resulted in a histologically normal liver without evidence of hepatosteatosis despite persistence of some abnormal biochemical parameters. This protection could result from the generation of creatine from the ingested GAA. Ethanol treatment for 6 wk exhibited changes in liver methionine metabolism and persistence of histological and biochemical defects as reported before. Further, when the rats were fed the GAA-supplemented ethanol diet, similar histological and biochemical changes as observed after 2 wk of combined treatment, including inflammation, macroand micro-vesicular steatosis and a marked decrease in the methylation index were noted. In addition, rats on the combined treatment exhibited increased liver toxicity and even early fibrotic changes in a subset of animals in this group. The worsening liver pathology could be related to the profound reduction in the hepatic methylation index, an increased accumulation of GAA and the inability of creatine generated to exert its hepato-protective effects in the setting of ethanol.CONCLUSION To conclude, prolonged exposure to a methyl consumer superimposed on chronic ethanol consumption causes persistent and pronounced liver damage.Natalia A Osna Dan Feng Murali Ganesan Priya F Maillacheruvu David J Orlicky Samuel W French Dean J Tuma Kusum K Kharbanda 2016World Journal of Gastroenterology2016,22,38:2
8Cypovirus capsid protein VP5 has nucleoside triphosphatase activity显示文摘As a major protein of cypovirus capsid shell, VP5 per-forms as the clamp protein to stabilize the capsid shellstructure (Yu et al., 2008). And as a part of viral RNA(vRNA) replication machinery, VP5 has been found topossess an ATP-independent RNA chaperoning activity(Yang et al., 2014). Here, we report that VP5 also has thenucleoside triphosphatase (NTPase) activity, which canhydrolyze all kinds of NTPs and dNTPs. Thus, ourfinding reveals that VP5 is a multifunctional protein thatmay be involved in diverse processes during cypovirallife cycle.Jie Yang Qi Qian Teng—Feng Li Xueli Yang Sok Jin W on Xi Zho 2017Virologica Sinica2017,32,4:2

11Electrochemical deposited amorphous FeNi hydroxide electrode for oxygen evolution reaction显示文摘The electrodeposition approach is significant in electrode fabrication for practical application.Herein,the electrodeposited amorphous NiFe hydroxide species for oxygen evolution reaction (OER) in water splitting reaction is demonstrated by revealing the synergistic effect influenced by the support electrode of Fe and Ni foil and the contents of Fe and Ni in the electrolyte.All the electrodeposited samples have an amorphous structure and similar profiles of binding energy and chemical states for Fe and Ni as characterized by the spectroscopic techniques.While the support effect and Fe/Ni synergistic effect are indeed observed for the varied catalytic performances observed for the different electrodes;the Ni foil supported catalyst exhibits much higher performance than that of the Fe foil supported catalyst,and the different redox potentials of Ni species in the different Fe/Ni electrode resulting from the Fe–Ni synergism are observed in the cyclic voltammetry curve analysis.The surface roughness and the electrochemical surface area are also influenced by the support effect and the Fe/Ni ratio in the plating electrolyte.The optimal electrode shows a very low overpotential of~200 mV to reach 10 mA cm^(-2),and very high catalytic stability by the consecutive cyclic voltammetry measurements and 20 h stability test.Though it has the largest electrochemical surface area,the highest catalytic efficiency for these active sites is also indicated by the specific activity and turnover frequency polarization curves.The current work shows the effective experience for the electrodeposited Fe/Ni based catalysts in large-scale fabrication,which can be more practical for hydrogen generation in the alkaline water electrolysis.Zhengzhi Yin Runze He Yongcai Zhang Ligang Feng Xiang Wu Thomas Wågberg Guangzhi Hu 2022Journal of Energy Chemistry2022,31,6:2
