1Prevalence and evolution of drug resistance HIV-1 variants in Henan, China显示文摘To understand the prevalence and evolution of drug resistant HIV strains in Henan China after the implementation of free antiretroviral therapy for AIDS patients. 45 drug nave AIDS patients, 118 AIDS patients who received three months antiretroviral therapy and 124 AIDS patients who received six months antiretroviral treatment were recruited in the southern part of Henan province. Information on general condition, antiretroviral medicines, adherence and clinical syndromes were collected by face to face interview. Meanwhile, 14ml EDTA anticoagulant blood was drawn. CD4/CD8 T cell count, viral load and genotypic drug resistance were tested. The rates of clinical improvement were 55.1% and 50.8% respectively three months and six months after antiretroviral therapy. The mean CD4 cell count after antiretroviral therapy was significantly higher than in drug nave patients. The prevalence rate of drug resistant HIV strains were 13. 9%, 45.4% and 62.7% in drug nave patients, three month treatment patients and six month treatment patients, respectively. The number of resistance mutation codons and the frequency of mutations increased significantly with continued antiretroviral therapy. The mutation sites were primarily at the 103, 106 and 215 codons in the three-month treatment group and they increased to 15 codon mutations in the six-month treatment group. From this result, the evolution of drug resistant strains was inferred to begin with the high level NNRTI resistant strain, and then develop low level resistant strains to NRTIs. The HIV strains with high level resistance to NVP and low level resistance to AZT and DDI were highly prevalent because of the AZT+DDI+NVP combination therapy. These HIV strains were also cross resistant to DLV, EFV, DDC and D4T. Poor adherence to therapy was believed to be the main reason for the emergence and prevalence of drug resistant HIV strains. The prevalence of drug resistant HIV strains was increased with the continu- ation of antiretroviral therapy in the southern part of Henan province. Measures, that could promote high level adherence, provide new drugs and change ART regimens in failing patients, should be implemented as soon as possible.Jing Yun LI Han Ping LI Lin LI Hong LI Zhe WANG Kun YANG Zuo Yi BAO Dao Min ZHUANG Si Yang LIU Yong Jian LIU Hui XING Yi Ming SHAO 2005Cell Research2005,15,11:34

3Inhibitory effects of miRNA-200c on chemotherapy-resistance and cell proliferation of gastric cancer SGC7901/DDP cells显示文摘Background and Objective: miRNA-200c can not only inhibit the aggressiveness of cancer cells but also increase the sensitivity of cells to antitumor drugs. However, some mechanisms are still unclear. Recent researches revealed that E-cadherin is more than an inhibitor of metastasis, and it also plays important roles in reversing drug resistance. We had previously found that miRNA-200c could not only induce the expression of E-cadherin but also increase the sensitivity of gastric cancer SGC7901/DDP cells to cisplatin (DDP). This study aimed to explore the effects of miRNA-200c on biological characteristics of SGC7901/DDP cells and the roles of E-cadherin in the regulatory pathway of miRNA-200c. Methods: SGC7901/DDP cells and its parental cell line SGC7901 cells were transfected with miRNA-200c precursor (Pre-200c) and E-cadherin siRNA, respectively. Real-time RT-PCR was used to detect miRNA-200c expression after transfection with Pre-200c in SGC7901/DDP cell line. Drug sensitivities to DDP, 5-fluorouracil (5-FU), paclitaxel, and adriamycin (ADR) after transfection were tested using MTT assay. The proliferation of SGC7901/DDP cells was also detected after transfection. The protein changes of E-cadherin, Bax, and Bcl-2 after transfection were detected by Western blot. Results: The miRNA-200c expression in SGC7901/DDP cells after transfection of Pre-200c was 7.128 ± 0.159 times of that in negative control (P < 0.05). The IC50 of DDP, 5-FU, paclitaxel, and ADR in Pre-200c-transfected group were significantly lower than that in negative control group (P < 0.05). Compared to the control group, cell proliferation was significantly decreased (P < 0.05). The relative protein expressions of E-cadherin and Bax in Pre-200c-transfected group were significantly higher than those in negative control group (P < 0.05), whereas Bcl-2 was significantly lower than that in control (P < 0.05). Additionally, E-cadherin protein expression was significantly inhibited after transfected with E-cadherin siRNA in SGC7901 cells. The Bax protein expression was significantly down-regulated by E-cadherin siRNA (P < 0.05), whereas the Bcl-2 expression was significantly up-regulated (P < 0.05). Conclusion: miRNA-200c can indirectly regulate apoptosis through E-cadherin in SGC7901/DDP cells, which may be a possible mechanism of miRNA-200c in reversing drug resistance and inhibiting proliferation.Yong Chen Jing Zuo Ying Liu Hong Gao Wei Liu 2010Chinese Journal of Cancer2010,29,12:18

5Microwave Exposure Impairs Synaptic Plasticity in the Rat Hippocampus and PC12 Cells through Over-activation of the NMDA Receptor Signaling Pathway显示文摘Objective The aim of this study is to investigate whether microwave exposure would affect the N-methyl-D-aspartate receptor(NMDAR) signaling pathway to establish whether this plays a role in synaptic plasticity impairment. Methods 48 male Wistar rats were exposed to 30 m W/cm2 microwave for 10 min every other day for three times. Hippocampal structure was observed through H&E staining and transmission electron microscope. PC12 cells were exposed to 30 m W/cm2 microwave for 5 min and the synapse morphology was visualized with scanning electron microscope and atomic force microscope. The release of amino acid neurotransmitters and calcium influx were detected. The expressions of several key NMDAR signaling molecules were evaluated. Results Microwave exposure caused injury in rat hippocampal structure and PC12 cells, especially the structure and quantity of synapses. The ratio of glutamic acid and gamma-aminobutyric acid neurotransmitters was increased and the intracellular calcium level was elevated in PC12 cells. A significant change in NMDAR subunits(NR1, NR2 A, and NR2B) and related signaling molecules(Ca2+/calmodulin-dependent kinase II gamma and phosphorylated c AMP-response element binding protein) were examined. Conclusion 30 m W/cm2 microwave exposure resulted in alterations of synaptic structure, amino acid neurotransmitter release and calcium influx. NMDAR signaling molecules were closely associated with impaired synaptic plasticity.XIONG Lu SUN Cheng Feng ZHANG Jing GAO Ya Bing WANG Li Feng ZUO Hong Yan WANG Shui Ming ZHOU Hong Mei XU Xin Ping DONG Ji YAO Bin Wei ZHAO Li PENG Rui Yun 2015Biomedical and Environmental Sciences2015,28,1:16
6Bone morphogenetic protein-7 represses hepatic stellate cell activation and liver fibrosis via regulation of TGF-β/Smad signaling pathway显示文摘BACKGROUND Liver fibrosis is a refractory disease whose persistence can eventually induce cirrhosis or even liver cancer.Early liver fibrosis is reversible by intervention.As a member of the transforming growth factor-beta(TGF-β)superfamily,bone morphogenetic protein 7(BMP7)has anti-liver fibrosis functions.However,little is known about BMP7 expression changes and its potential regulatory mechanism as well as the relationship between BMP7 and TGF-βduring liver fibrosis.In addition,the mechanism underlying the anti-liver fibrosis function of BMP7 needs to be further explored.AIM To investigate changes in the dynamic expression of BMP7 during liver fibrosis,interactions between BMP7 and TGF-β1,and possible mechanisms underlying the anti-liver fibrosis function of BMP7.METHODS Changes in BMP7 expression during liver fibrosis and the interaction between BMP7 and TGF-β1 in mice were observed.Exogenous BMP7 was used to treat mouse primary hepatic stellate cells(HSCs)to observe its effect on activation,migration,and proliferation of HSCs and explore the possible mechanism underlying the anti-liver fibrosis function of BMP7.Mice with liver fibrosis received exogenous BMP7 intervention to observe improvement of liver fibrosis by using Masson’s trichrome staining and detecting the expression of the HSC activation indicator alpha-smooth muscle actin(α-SMA)and the collagen formation associated protein type I collagen(Col I).Changes in the dynamic expression of BMP7 during liver fibrosis in the human body were further observed.RESULTS In the process of liver fibrosis induced by carbon tetrachloride(CCl4)in mice,BMP7 protein expression first increased,followed by a decrease;there was a similar trend in the human body.This process was accompanied by a sustained increase in TGF-β1 protein expression.In vitro experiment results showed that TGF-β1 inhibited BMP7 expression in a time-and dose-dependent manner.In contrast,high doses of exogenous BMP7 inhibited TGF-β1-induced activation,migration,and proliferation of HSCs;this inhibitory effect was associated with upregulation of pSmad1/5/8 and downregulation of phosphorylation of Smad3 and p38 by BMP7.In vivo experiment results showed that exogenous BMP7 improved liver fibrosis in mice.CONCLUSION During liver fibrosis,BMP7 protein expression first increases and then decreases.This changing trend is associated with inhibition of BMP7 expression by sustained upregulation of TGF-β1 in a time-and dose-dependent manner.Exogenous BMP7 could selectively regulate TGF-β/Smad pathway-associated factors to inhibit activation,migration,and proliferation of HSCs and exert antiliver fibrosis functions.Exogenous BMP7 has the potential to be used as an antiliver fibrosis drug.Gao-Liang Zou Shi Zuo Shuang Lu Rui-Han Hu Yin-Ying Lu Jing Yang Kai-Sheng Deng Ye-Ting Wu Mao Mu Juan-Juan Zhu Jing-Zhang Zeng Bao-Fang Zhang Xian Wu Xue-Ke Zhao Hai-Yang Li 2019World Journal of Gastroenterology2019,25,30:15
7Relationship between serum homocysteine levels and long-term outcomes in patients with ST-segment elevation myocardial infarction显示文摘Background:The mortality of cardiovascular disease is constantly rising,and novel biomarkers help us predict residual risk.This study aimed to evaluate the predictive value of serum homocysteine (HCY) levels on prognosis in patients with ST-segment elevation myocardial infarction (STEMI).Methods:The 419 consecutive patients with STEMI,treated at one medical center,from March 2010 to December 2015 were retrospectively investigated.Peripheral blood samples were obtained within 24 h of admission and HCY concentrations were measured using an enzymatic cycling assay.The patients were divided into high HCY level (H-HCY) and low HCY level (L-HCY) groups.Short- and long-term outcomes were compared,as were age-based subgroups (patients aged 60 years and younger vs.those older than 60 years).Statistical analyses were mainly conducted by Student t-test,Chi-squared test,logistic regression,and Cox proportional-hazards regression.Results:The H-HCY group had more males (84.6% vs.75.4%,P=0.018),and a lower prevalence of diabetes (20.2% vs.35.5%,P<0.001),compared with the L-HCY group.During hospitalization,there were seven mortalities in the L-HCY group and 10 in the H-HCY group (3.3% vs.4.8%,P= 0.440).During the median follow-up period of 35.8 (26.9–46.1) months,33 (16.2%) patients in the L-HCY group and 48 (24.2%) in the H-HCY group experienced major adverse cardiovascular and cerebrovascular events (MACCE)(P=0.120).History of hypertension (hazard ratio [HR]:1.881,95% confidence interval [CI]:1.178–3.005,P=0.008) and higher Killip class (HR:1.923,95% CI:1.419–2.607,P<0.001),but not HCY levels (HR:1.007,95% CI:0.987–1.027,P=0.507),were significantly associated with long-term outcomes.However,the subgroup analysis indicated that in older patients,HCY levels were significantly associated with long-term outcomes (HR:1.036,95% CI:1.011–1.062,P=0.005).Conclusion:Serum HCY levels did not independently predict in-hospital or long-term outcomes in patients with STEMI;however,among elderly patients with STEMI,this study revealed a risk profile for late outcomes that incorporated HCY level.Jin Si Xue-Wen Li Yang Wang Ying-Hua Zhang Qing-Qing Wu Lei-Min Zhang Xue-Bing Zuo Jing Gao Jing Li 2019Chinese Medical Journal2019,,9:15

11Prognostic evaluation of postoperative adjuvant therapy for operable cervical cancer:10 years'experience of National Cancer Center in China显示文摘Objective: The aim of this study was to investigate the prognostic factors and to evaluate the impact of adjuvant therapy on clinical outcome for early-stage cervical cancer.Methods: The clinical-pathological data of all 1,335 patients with the International Federation of Gynecology and Obstetrics(FIGO) Ib–IIa cervical cancer treated with primary radical surgery at the Chinese National Cancer Center between May 2007 and Dec 2013 were retrospectively reviewed.The median follow-up was 70 months.Results: Of all the patients,61.6% of the cases received adjuvant therapy,with 5-year disease-free survival(DFS)of 92.1% and 5-year overall survival(OS) of 95.0%.In multivariate analysis,differentiation of G3(P<0.05),lymph node metastasis(LNM,P<0.05) and lymphovascular space invasion(LVSI,P<0.05) were independent predictors for OS,while LNM(P<0.05),deep stroma invasion(DSI,P<0.05) and LVSI(P<0.05) were independent factors for DFS.The samples were stratified by histologic type,and cervical squamous cell carcinoma(SCC) was found to share the same independent factors except for differentiation of OS.As to patients with cervical adenocarcinoma/adenosquamous carcinoma(AC/ASC),differentiation was the independent predictor of OS(P<0.05); and LVSI of DFS(P<0.05).Of 236 patients with high-risk factors,there was no significant difference in survival between concurrent chemoradiotherapy(CCRT,n=195),radiotherapy(RT,n=24),and chemotherapy(CT,n=17).Among the 190 patients with LNM who underwent CCRT,124 cases showed improved DFS after sequential CT(P=0.118),with a recurrence rate decrease of 14%,though the difference was not statistically significant.Patients with single intermediate-risk factors like DSI or LVSI were found to partially benefit from adjuvant therapy,but the difference was not statistically significant.Conclusions: LNM,LVSI,DSI and differentiation were found to be independent prognostic factors for operable cervical cancer.Aggressive postoperative adjuvant therapy based on single risk factors in Chinese National Cancer Center could benefit survival.CCRT+CT outperformed CCRT in high-risk patients.For patients with single non-high-risk factor,the role of adjuvant therapy needs to be further discussed.Tong Shu Dan Zhao Bin Li Yating Wang Shuanghuan Liu Pingping Li Jing Zuo Ping Ba i RongZhang Lingying Wu 2017Chinese Journal of Cancer Research2017,29,6:12
12Diagnostic value of 5 serum biomarkers for hepatocellular carcinoma with different epidemiological backgrounds:A large-scale,retrospective study显示文摘Objective:Hepatocellular carcinoma(HCC)is a lethal global disease that requires an accurate diagnosis.We assessed the potential of 5 serum biomarkers(AFP,AFU,GGT-II,GPC3,and HGF)in the diagnosis of HCC.Methods:In this retrospective study,we measured the serum levels of each biomarker using ELISAs in 921 participants,including 298 patients with HCC,154 patients with chronic hepatitis(CH),122 patients with liver cirrhosis(LC),and 347 healthy controls from 3 hospitals.Patients negative for hepatitis B surface antigen and hepatitis C antibody(called'NBNC-HCC')and patients positive for the above indices(called'HBV-HCC and HCV-HCC')were enrolled.The selected diagnostic model was constructed using a training cohort(n=468),and a validation cohort(n=453)was used to validate our results.Receiver operating characteristic analysis was used to evaluate the diagnostic accuracy.Results:Theα-L-fucosidase(AFU)/α-fetoprotein(AFP)combination was best able to distinguish NBNC-HCC[area under the curve:0.986(95%confidence interval:0.958–0.997),sensitivity:92.6%,specificity:98.9%]from healthy controls in the test cohort.For screening populations at risk of developing HCC(CH and LC),the AFP/AFU combination improved the diagnostic specificity for early-stage HCC[area under the curve:0.776(0.712–0.831),sensitivity:52.5%,specificity:91.6%in the test group].In all-stage HBV-HCC and HCV-HCC,AFU was also the best candidate biomarker combined with AFP[area under the curve:0.835(0.784–0.877),sensitivity 69.1%,specificity:87.4%in the test group].All results were verified in the validation group.Conclusions:The AFP/AFU combination could be used to identify NBNC-HCC from healthy controls and hepatitis-related HCC from at-risk patients.Dongming Liu Yi Luo Lu Chen Liwei Chen Duo Zuo Yueguo Li Xiaofang Zhang Jing Wu Qing Xi Guangtao Li Lisha Qi Xiaofen Yue Xiehua Zhang Zhuoyu Sun Ning Zhang Tianqiang Song Wei Lu Hua Guo 2021Cancer Biology & Medicine2021,18,1:10
13An update: Epstein-Barr virus and immune evasion via microRNA regulation显示文摘Epstein-Barr virus(EBV) is an oncogenic virus that ubiquitously establishes life-long persistence in humans. To ensure its survival and maintain its B cell transformation function, EBV has developed powerful strategies to evade host immune responses. Emerging evidence has shown that micro RNAs(mi RNAs) are powerful regulators of the maintenance of cellular homeostasis. In this review, we summarize current progress on how EBV utilizes mi RNAs for immune evasion. EBV encodes mi RNAs targeting both viral and host genes involved in the immune response. The mi RNAs are found in two gene clusters, and recent studies have demonstrated that lack of these clusters increases the CD4^+ and CD8^+ T cell response of infected cells. These reports strongly indicate that EBV mi RNAs are critical for immune evasion. In addition, EBV is able to dysregulate the expression of a variety of host mi RNAs, which influence multiple immune-related molecules and signaling pathways. The transport via exosomes of EBV-regulated mi RNAs and viral proteins contributes to the construction and modification of the inflammatory tumor microenvironment.During EBV immune evasion, viral proteins, immune cells, chemokines, pro-inflammatory cytokines, and pro-apoptosis molecules are involved. Our increasing knowledge of the role of mi RNAs in immune evasion will improve the understanding of EBV persistence and help to develop new treatments for EBV-associated cancers and other diseases.Lielian Zuo Wenxin Yue Shujuan Du Shuyu Xin Jing Zhang Lingzhi Liu Guiyuan Li Jianhong Lu 2017Virologica Sinica2017,32,3:9
14Inhibitive effects of chlortetracycline on performance of the nitritation-anaerobic ammonium oxidation(anammox)process and strategies for recovery显示文摘The short-and long-term effects of chlortetracycline(CTC) on the nitritation-anaerobic ammonium oxidation(anammox) process were evaluated. The half maximal inhibitory concentration of CTC in the batch tests of the nitritation-anammox process was 278.91 mg/L at an exposure time of 12 hr. The long-term effects of CTC on the process were examined in a continuous-flow nitritation-anammox reactor. Within 14 days, the nitrogen removal rate significantly decreased from 0.61 to 0.25 kg N/m^3/day with 60 mg/L CTC in the influent.The performance suppressed by CTC barely recovered, even after CTC was removed from the influent. Furthermore, the inhibition of CTC also reduced the relative abundance of ammonium oxidizing bacteria(AOB) and anaerobic ammonium oxidizing bacteria(An AOB)in the reactor, resulting in both a decreased amount of and an imbalance between AOB and An AOB. When fresh anammox sludge was reseeded into the nitritation-anammox reactor,the nitrogen removal rate recovered to 0.09 ± 0.03 kg N/m^3/day.Hong Yao Huayu Li Jing Xu Lushen Zuo 2018Journal of Environmental Sciences2018,30,8:8

16Low serum albumin levels predict poor outcome in patients with acute ischaemic stroke or transient ischaemic attack显示文摘Background To examine the relationship of serum albumin with poor functional outcome and mortality in patients with acute ischaemic stroke(AIS)or transient ischaemic attack(TIA),and perform a meta-analysis to summarise the association.Methods We analysed data from the Third China National Stroke Registry(CNSR-Ⅲ).Patients were divided into four groups based on serum albumin levels at admission.The outcomes included poor functional outcome(modified Rankin Scale(mRS)score of 3 to 6)and mortality at 3 months and 1 year.Multiple logistic regression models and Cox regression models were used to evaluate the association,respectively.We used a fixed-effect model to calculate the risk ratio for poor functional outcome and a random-effect model for mortality in the meta-analysis.Results A total of 13618 patients were enrolled.During the 3-month follow-up period,compared with 40 to 44.9 g/L group,patients in<35 g/L group had an increased risk of poor functional outcome and mortality(adjusted OR 1.37(95%CI 1.12 to 1.67);adjusted HR 2.13(95%CI 1.41 to 3.23)).The relationship in per 10 g/L decreased serum albumin with prognosis was consistently inversed(adjusted OR 1.17(95%CI 1.01 to 1.35);adjusted HR 1.86(95%CI 1.30 to 2.64)).Also,low serum albumin levels were independently correlated with clinical outcomes at 1 year.In the meta-analysis,the OR for poor functional outcome pooled 3 studies per 1 g/L decrease was 1.03(95%CI 1.02 to 1.05),and the HR for mortality pooled 5 studies was 1.07(95%CI 1.03 to 1.11).Conclusions Low serum albumin levels predict poor functional outcome and mortality in patients with AIS or TIA.Hongyu Zhou Anxin Wang Xia Meng Jinxi Lin Yong Jiang Jing Jing Yingting Zuo Yilong Wang Xingquan Zhao Hao Li Yongjun Wang 2021Stroke & Vascular Neurology2021,6,3:7
17Deep learning in optical metrology:a review显示文摘With the advances in scientific foundations and technological implementations,optical metrology has become versatile problem-solving backbones in manufacturing,fundamental research,and engineering applications,such as quality control,nondestructive testing,experimental mechanics,and biomedicine.In recent years,deep learning,a subfield of machine learning,is emerging as a powerful tool to address problems by learning from data,largely driven by the availability of massive datasets,enhanced computational power,fast data storage,and novel training algorithms for the deep neural network.It is currently promoting increased interests and gaining extensive attention for its utilization in the field of optical metrology.Unlike the traditional,,physics-basedH approach,deep-learning-enabled optical metrology is a kind of,/data-drivenw approach,which has already provided numerous alternative solutions to many challenging problems in this field with better performances.In this review,we present an overview of the current status and the latest progress of deep-learning technologies in the field of optical metrology.We first briefly introduce both traditional image-processing algorithms in optical metrology and the basic concepts of deep learning,followed by a comprehensive review of its applications in various optical metrology tasks,such as fringe denoising,phase retrieval,phase unwrapping,subset correlation,and error compensation.The open challenges faced by the current deep-learning approach in optical metrology are then discussed.Finally,the directions for future research are outlined.Chao Zuo Jiaming Qian Shijie Feng Wei Yin Yixuan Li Pengfei Fan Jing Han Kemao Qian Qian Chen 2022Light(Science & Applications)2022,11,4:7
18Clinical outcomes and immune reconstitution in 103 advanced AIDS patients undergoing 12-month highly active antiretroviral therapy显示文摘Background Highly active antiretroviral therapy (HAART) produces profound suppression of HIV replication, substantial increase in CD4+ T cells, and partial reconstitution of the immune system. However, the numbers of subjects were small in previous Chinese studies. This study evaluated the efficacy and side effects of HAART in Chinese advanced AIDS patients. Methods One hundred and three antiretroviral drug naive AIDS patients were enrolled in this study and were divided into two groups by their baseline CD4+ count: <100 cells/μl or ≥100 cells/μl. Clinical, virological and immunological outcomes were monitored at baseline and at 1, 3, 6, 9 and 12 months during the course of treatment with HAART. Results One patient died and another was lost from the follow-up. For the remaining 101 HIV/AIDS patients at the 12th month during the HAART, the plasma viral load (VL) was reduced to (3.2±0.7) lg copies/ml, the CD4+ count increased to (168±51) cells/μl [among which the naive phenotype (CD45RA+CD62L+) increased to (49±27) cells/μl and the memory phenotype (CD45RA-) increased to (119±55) cells/μl], and the percentage of CD4+CD28+ cells increased. At the same time, there was a significant reduction of CD8+ T cell activation. In the 69 patients with the baseline CD4+ count <100 cells/μl, 37 had a VL <50 copies/ml; while in the 34 patients with the baseline CD4+ count ≥100 cells/μl, 25 had a VL <50 copies/ml, the difference between the two groups was statistically significant. The CD4+ T cell count showed a two-phase increase during HAART and a significant positive correlation was shown between the change of CD4+ count and plasma VL. Over 12 months of HAART, 10 patients had gastrointestinal side effects, 13 peripheral neuritis, 7 hepatic lesions, 8 hematological side effects, 8 skin rashes, 10 lipodystrophy and 1 renal calculus. Conclusions Immune reconstitution as well as the significantly improved clinical outcomes is observed in Chinese advanced AIDS patients after HAART. Side effects are common during HAART and require clinical attention.DAI Yi QIU Zhi-feng LI Tai-sheng HAN Yang ZUO Ling-yan XIE Jing MA Xiao-jun LIU Zheng-yin WANG Ai-xia 2006Chinese Medical Journal2006,,20:6
19Oxidative modification of caspase-9 facilitates its activation via disulfide-mediated interaction with Apaf-1显示文摘细胞内部的反应的氧种类(ROS ) 被知道调整 apoptosis。caspase-9 的激活,在 mitochondrial apoptotic 串联的起始的 caspase,仔细与被联系 ROS,而是它是不清楚的是否 ROS 经由直接氧化的修正调整 caspase-9。阐明的现在的学习目的由哪个 ROS 调停的分子的机制 caspase-9 激活。我们的结果证明细胞的氧化状态便于 caspase-9 激活。氢过氧化物治疗引起 caspase-9 和 apoptosis 的激活,并且支持在 caspase-9 和 apoptotic 之间的一个相互作用激活朊酶的因素 1 (Apaf-1 ) 经由二硫化物形成。另外,在里面一在里面 vitro 没有线粒体的系统, thiol 氧化剂 diamide 由便于连接二硫化物的建筑群的形成支持 caspase-9 和 caspase-9/Apaf-1 相互作用的汽车劈开。最后,在 caspase-9 的 C403 的一个点变化通过二硫化物形成的废除损害有 Apaf-1 的两支持 H2O2 的 caspase-9 激活和相互作用。在细胞色素 c 和 C403S 异种之间的协会在细胞色素 c 和野类型的 caspase-9 之间是比那显著地弱的,显示 caspase-9 的那氧化修正贡献在氧化应力下面的 apoptosome 形成。一起拿,由 ROS 的 caspase-9 的氧化修正能调停它和 Apaf-1 的相互作用,和罐头因此支持它的汽车劈开和激活。这机制可以在氧化应力下面便于 apoptosome 形成和 caspase-9 激活。Yong Zuo Binggang Xiang Jie Yang Xuxu Sun Yumei Wang Hui Cang Jing Yi 2009Cell Research2009,19,4:6
20Improved MOEA/D for Dynamic Weapon-Target Assignment Problem显示文摘Conducting reasonable weapon-target assignment( WTA) with near real time can bring the maximum awards with minimum costs which are especially significant in the modern war. A framework of dynamic WTA( DWTA) model based on a series of staged static WTA( SWTA) models is established where dynamic factors including time window of target and time window of weapon are considered in the staged SWTA model. Then,a hybrid algorithm for the staged SWTA named Decomposition-Based Dynamic Weapon-target Assignment( DDWTA) is proposed which is based on the framework of multi-objective evolutionary algorithm based on decomposition( MOEA / D) with two major improvements: one is the coding based on constraint of resource to generate the feasible solutions, and the other is the tabu search strategy to speed up the convergence.Comparative experiments prove that the proposed algorithm is capable of obtaining a well-converged and well diversified set of solutions on a problem instance and meets the time demand in the battlefield environment.Ying Zhang Rennong Yang Jialiang Zuo Xiaoning Jing 2015Journal of Harbin Institute of Technology(New Series)2015,22,6:6
