4Surface characterization of steel/steel contact lubricated by PA06 with novel black phosphorus nanocomposites显示文摘In the present work,two types of novel nano additives,titanium sulfonate ligand/black phosphorus(TiLi/BP)and titanium dioxide/black phosphorus(TiCVBP)nanocomposites,were prepared.The tribological behavior of the steel/steel friction pairs lubricated by polyalphaolefins type 6(PA06)containing the nanocomposites under boundary lubrication was studied.The worn surfaces were analyzed using modem surface techniques.The experimental results show that the rubbed surfaces became smooth and showed little wear with the addition of the nanocomposites.TiO_(2)/BP nanocomposites can significantly improve the lubricity of BP nanosheets under high contact stress.The synergistic roles of the load-bearing abilities and rolling effect of TiO_(2) nanoparticles,the slip induced by the BP with its layered structure,and the establishment of a tribofilm on the sliding interface are the basis of the tribological mechanisms.Zhiheng LUO Jingyuan YU Yufu XU He XI Gang CHENG Lulu YAO Ruhong SONG Karl D DEARN 2021Friction2021,9,4:2
5Impact of virus genotype on interferon treatment of patients with chronic hepatitis C: a multicenter controlled study显示文摘BACKGROUND: Some factors have been reported to besassociated with a greater likelihood of sustained viral re-sponse ( SVR) in the interferon (IFN) treatment of chronichepatitis C. The factors include HCV genotype, HCVRNA level in serum, state of liver disease, baseline bodyweight, age, sex, and race. The aim of this trial was to in-vestigate the influence of HCV genotype on the IFN treat-ment of patients with chronic hepatitis C.METHODS: The genotypes of HCV virus were determinedin the patients with chronic hepatitis C from several hospi-tals of China enrolled into the randomized, opened andcontrolled trial of Peg-IFN alpha-2a (pegasys) treatment,controlled with IFN-α-2a (roferon-A). The serum ALTlevels and HCV RNA concentrations of the patients weredetected before and at the end of treatment and during thefollow-up. The influence of HCV genotype on the IFNtreatment of patients with chronic hepatitis C was analyzedin intention-to-treat (ITT) population.RESULTS: The HCV genotypes of 202 patients were deter-mined. Of these patients, 158(78.22%) were infected withgenotype 1 HCV and 44(21.78%) with genotype non-1.The viral response at the end of treatment (ETVR) andsustained viral response (SVR) rates were 53.80% and25.32% respectively in patients with genotype 1 HCV, butthey were 61.36% and 43.18% in patients with genotypenon-1. The difference of SVR between patients with geno-type 1 HCV and those with genotype non-1 was significant(P =0.021). After being grouped by the used drugs, theETVR rates of patients infected with genotype 1 and non-1HCV were 76.83% and 80.95% in the patients treated withpegasys (P =0.686); but their SVR rates were 35.37% and66.67% (P =0. 01). The viral relapse rate of genotype 1HCV (55.56%) was significantly higher than that of geno-type non-1 HCV (23.53%) (P=0.02). In roferon-A group,the ETVR and SVR rates of patients with genotype 1 HCVwere 28.95% and 14.47% respectively, which were lowerbut not more significant than those of patients with geno-type non-1 HCV (43.48% and 21.74%). Moreover, the vi-ral relapse rate of genotype 1 HCV (72.73%) was higherbut not more significant than that of genotype non-1 HCV(50.00%) (P=0.21).CONCLUSION: HCV genotype could affect the efficacies,mainly sustained responses, of IFN treatment in patientswith chronic hepatitis C, and the effects of IFN are relatedto drugs and therapeutic course.Yao Xie, Dao-Zhen Xu, Zhi-Meng Lu, Kang-Xian Luo, Ji-Dong Jia, Yu-Ming Wang,Gui-Zhen Zhao, Shu-Lin Zhang and Da-Zhi Zhang Department of Infeetious Diseases , Beijing Ditan Hos-pital, Beijing 100011 , China Department of Infec-tious Diseases, Ruijin Hospital, Shanghai 200025, China De-partment of Infectious Diseases, Naifang Hospital, First Military Medical U-niversity, Guangzhou 510515, China (Luo KX) Center of Liver Disease,Beijing Friendship Hospital, Beijing 100050, China (Jia J D ) Institute ofInfectious Disease, Southwest Hospital, Third Military Medical University,Chongqing 410032, China Department of Infectious Disea-ses, Second Hospital, China Medical University, Shenyang 110004, China Department of Infectious Diseases, First Hospital, Xi’ an Jiao-tong University, Xi’ an 710061 , China ) Liver Disease Centerof Chongqing, Second Hospital, Chongqing Medical University,Chongqing 410010, China 2004Hepatobiliary & Pancreatic Diseases International2004,3,3:2
6Terahertz Semiconductor Quantum Well Devices显示文摘For eventually providing terahertz science with compact and convenient devices,terahertz (1~10THz) quantum-well photodetectors and quantum-cascade lasers are investigated.The design and projected detector performance are presented together with experimental results for several test devices,all working at photon energies below and around optical phonons.Background limited infrared performance (BLIP) operations are observed for all samples (three in total),designed for different wavelengths.BLIP temperatures of 17,13,and 12K are achieved for peak detection frequencies of 9.7THz(31μm),5.4THz(56μm),and 3.2THz(93μm),respectively.A set of THz quantum-cascade lasers with identical device parameters except for doping concentration is studied.The δ-doping density for each period varies from 3.2×1010 to 4.8×1010cm-2.We observe that the lasing threshold current density increases monotonically with doping concentration.Moreover,the measurements for devices with different cavity lengths provide evidence that the free carrier absorption causes the waveguide loss also to increase monotonically.Interestingly the observed maximum lasing temperature is best at a doping density of 3.6×1010cm-2.Liu H C Luo H Ban D Waichter M Song C Y Wasilewski Z R Buchanan M Aers G C SpringThorpe A J Cao J C Feng S L Williams B S Hu Q 2006Journal of Semiconductors2006,27,4:2
7A unique deubiquitinase that deconjugates phosphoribosyl-linked protein ubiquitination显示文摘Ubiquitination 调整主人免疫的许多方面并且因此是为传染代理人的一个普通目标。最近的研究表明了细菌的病原体 Legionella pneumophila 的方面受动器家庭的成员攻击不要求主人 ubiquitination 机械的 E1 和 E2 酶的新奇 ubiquitination 机制与 endoplasmic 蜂窝胃联系的几小 GTPases。在这种情况中, ubiquitin 被一项 mono-ADP-ribosyltransferase 活动被 ADP-ribosylation 首先在 Arg 42 激活;中介然后被也住在 SdeA 以内的一项 phosphodiesterase 活动劈开,有到经由一个 phosphoribosyl 连接器的底层蛋白质的丝氨酸残余的 ubiquitin 的附件的伴随物。这里,我们证明方面的效果被 SidJ 反对,一个受动器由位于为方面家庭(SdeC, SdeB 和 SdeA ) 的三个成员编码的地点的基因编码了。SidJ 由劈开连接 phosphoribosylated ubiquitin 到蛋白质底层的 phosphodiester 契约颠倒修改方面的底层的 ubiquitination。SidJ 也显示古典 deubiquitinase 活动但是不要求催化半胱氨酸残余。进一步, SidJ 的这些 deubiquitinase 活动为它在 L 的角色是必要的。pneumophila 感染。最后, SidJ 的活动为高效地在细菌的举起以后在一些小时以内在感染的房间减少许多 ubiquitinated Rab33b 被要求。我们的结果作为工作在方面受动器的活动强加时间的规定的 ubiquitin-deconjugating 酶建立 SidJ。SidJ 可能在表明串联的未来研究是重要的由这唯一的 ubiquitination 调停了,潜在地也在真核细胞的房间调整细胞的过程的。Jiazhang Qiu Kaiwen Yu Xiaowen Fei Yao Liu Emesto S Nakayasu Paul D Piehowski Jared B Shaw Kedar Puva Chittaranjan Das Xiaoyun Liu Zhao-Qing Luo 2017Cell Research2017,27,7:2
