| 1 | Polymorphism in the interleukin-17A promoter contributes to gastric cancer显示文摘AIM:To evaluate the contribution of the G-197A polymorphism in the interleukin-17(IL-17)promoter region to gastric cancer risk in an Iranian population.METHODS:We performed a case control study using samples from 161 individuals with gastric cancer and171 healthy controls.For each individual,the G-197A genotype was determined by restriction fragment length polymorphism analysis of polymerase chain reaction-amplified fragments.Statistical analyses were performed to determine whether any demographic or behavioral factors,infection with Helicobacter pylori(H.pylori),or a particular G-197A genotype was associated with gastric cancer risk.RESULTS:We found that the G-197A genotype wassignificantly associated with increased gastric cancer risk(P=0.001).Patients who were homozygous(AA)at position-197 were 2.9 times more likely to develop disease(95%CI:1.56-5.4;P=0.001).Furthermore,logistic regression analysis revealed that the presence of a single A allele increased the risk of gastric cancer up to 1.7-fold(95%CI:1.26-2.369;P=0.001).This association was observed for early stage gastric adenocarcinomas only,and was not linked to H.pylori infection.CONCLUSION:These results suggest that carrying one or more G-197A polymorphisms at position-197 in the IL-17 promoter region significantly increases gastric cancer risk in this patient population. | Alireza Rafiei Vahid Hosseini Ghasem Janbabai Abuzar Ghorbani Abulghasem Ajami Touraj Farzmandfar Maedeh Darzyani Azizi Jeremy J Gilbreath D Scott Merrell | 2013 | World Journal of Gastroenterology2013，19，34： | 7 |
| 2 | Regulation of flowering time in chrysanthemum by the R2R3 MYB transcription factor CmMYB2 is associated with changes in gibberellin metabolism显示文摘The switch from vegetative growth to reproductive growth is a key event in the development of a plant.Here,the product of the chrysanthemum gene CmMYB2,an R2R3 MYB transcription factor that is localized in the nucleus,was shown to be a component of the switching mechanism.Plants engineered to overexpress CmMYB2 flowered earlier than did wild-type plants,while those in which CmMYB2 was suppressed flowered later.In both the overexpression and RNAi knockdown plants,a number of genes encoding proteins involved in gibberellin synthesis or signaling,as well as in the response to photoperiod,were transcribed at a level that differed from that in the wild type.Both yeast two-hybrid and bimolecular fluorescence complementation assays revealed that CmMYB2 interacts with CmBBX24,a zinc-finger transcription factor known to regulate flowering by its influence on gibberellin synthesis. | Lu Zhu Yunxiao Guan Yanan Liu Zhaohe Zhang Muhammad Abuzar Jaffar Aiping Song Sumei Chen Jiafu Jiang Fadi Chen | 2020 | Horticulture Research2020，7，1： | 5 |

| 4 | Vibration analysis of damaged and undamaged steel structure systems: cantilever column and frame显示文摘This paper presents the experimental and numerical studies conducted on a steel column and a steel frame structure using free vibration analysis.The effects of damages on structures were investigated,which were simulated by introducing multiple cracks at different locations in the experimental and numerical models.The acceleration responses of the test models,were recorded through an accelerometer,and were used to calibrate the numerical models developed in finite element based software.Modal frequencies of damaged and undamaged structures were compared and analyzed,to derive relationships for damaged and undamaged structures’frequencies in terms of crack depth.It was found that,due to the presence of cracks,the mechanical properties of a structure changes,whereby,the modal frequencies decrease.An approximately linear trend was observed for the frequency decrease with the increase in crack depth,which was also confirmed by the numerical models.The derived relationships were extended to further develop a mechanics-based damage scale for steel structures,to help facilitate structural health monitoring and screening of vulnerable structures. | Muhammad Abuzar Khan Kareem Akhtar Naveed Ahmad Feroz Shah Naeem Khattak | 2020 | Earthquake Engineering and Engineering Vibration2020，19，3： | 1 |

| 9 | 荫蔽和微生物可在分子水平上调控植物激素以增强植物的耐旱性显示文摘植物在其生命周期内会受到一系列不利环境的影响。其中,干旱胁迫是限制农业生产力的重要因素之一。为了在逆境的环境中得以生存,植物进化出了识别环境胁迫严重性的机制。植物可通过多种方式调节激素活性,以减轻干旱带来的不良影响。受荫蔽和微生物调控,植株的抗旱性提高,产量损失减少。脱落酸、生长素和乙烯等植物激素,可调控多种代谢途径,在荫蔽和微生物介导的植株抗旱性增强过程中起着重要作用。如我们的调控模型所示,CLAVATA3/EMBRYOSURROUNDING REGION-RELATED 25多肽因其可影响ABA合成而在此过程中具有重要作用。 | Muhammad Ahsan Asghar Bushra Ahmad Ali Raza Bilal Adil Hafz Hassan Javed Muhammad Umer Farooq Abuzar Ghafoor Muhammad Iftikhar Hussain Iram Shafq Hassan Karim Xin Sun Wenyu Yang Gábor Kocsy Junbo Du | 2022 | Journal of Plant Ecology2022，15，6： | 0 |
| 10 | Adaptive Event-Triggering Consensus for Multi-Agent Systems with Linear Time-Varying Dynamics显示文摘In this paper,the authors study the fully distributed event-triggering consensus problem for multi-agent systems with linear time-varying dynamics,where each agent is described by a linear time-varying system.An adaptive event-triggering protocol is proposed for time-varying multi-agent systems under directed graph.Based on the Gramian matrix of linear time-varying systems,the design of control gain is done and sufficient conditions ensuring the consensus of linear time-varying multiagent systems are obtained.It is shown that the coupling strength is closely related to the triggering condition.When it comes to undirected graph,it is shown that the coupling strength is independent on the triggering condition and thus the design procedure is of more freedom than the directed case.In addition,it is also proved that Zeno behaviours can be excluded in the proposed protocols.A numerical example is presented to demonstrate the effectiveness of the theoretical results. | ZHANG Wenbing ABUZAR HUSSEIN MOHAMMED Atitalla BAO Jiatong LIU Yurong | 2022 | Journal of Systems Science & Complexity2022，35，5： | 0 |
| 11 | User scheduling and power allocation for downlink multi-cell multi-carrier NOMA systems显示文摘In Non-Orthogonal Multiple Access(NOMA),the best way to fully exploit the benefits of the system is the efficient resource allocation.For the NOMA power domain,the allocation of power and spectrum require solving the mixed-integer nonlinear programming NP-hard problem.In this paper,we investigate user scheduling and power allocation in Multi-Cell Multi-Carrier NOMA(MCMC-NOMA)networks.To achieve that,we consider Weighted Sum Rate Maximization(WSRM)and Weighted Sum Energy Efficiency Maximization(WSEEM)problems.First,we tackle the problem of user scheduling for fixed power using Fractional Programming(FP),the Lagrange dual method,and the decomposition method.Then,we consider Successive Pseudo-Convex Approximation(SPCA)to deal with the WSRM problem.Finally,for the WSEEM problem,SPCA is utilized to convert the problem into separable scalar problems,which can be parallelly solved.Thus,the Dinkelbach algorithm and constraints relaxation are used to characterize the closed-form solution for power allocation.Extensive simulations have been implemented to show the efficiency of the proposed framework and its superiority over other existing schemes. | Abuzar B.M.Adam Xiaoyu Wan Zhengqiang Wang | 2023 | Digital Communications and Networks2023，9，1： | 0 |
