| 1 | HOTAIR:an oncogenic long non-coding RNA in different cancers显示文摘Long non-coding RNAs(lncRNAs) refer to a group of RNAs that are usually more than 200 nucleotides and are not involved in protein generation. Instead, lncRNAs are involved in different regulatory processes, such as regulation of gene expression. Different lncRNAs exist throughout the genome. Lnc RNAs are also known for their roles in different human diseases such as cancer. HOTAIR is an lnc RNA that plays a role as an oncogenic molecule in different cancer cells, such as breast, gastric, colorectal, and cervical cancer cells. Therefore, HOTAIR expression level is a potential biomarker for diagnostic and therapeutic purposes in several cancers. This RNA takes part in epigenetic regulation of genes and plays an important role in different cellular pathways by interacting with Polycomb Repressive Complex 2(PRC2). In this review, we describe the molecular function and regulation of HOTAIR and its role in different types of cancers. | Mohammadreza Hajjari Abbas Salavaty | 2015 | Cancer Biology & Medicine2015,12,1: | 53 |
| 2 | 黄瓜游离小孢子培养诱导成胚和植株再生显示文摘以10个不同基因型黄瓜为试材进行游离小孢子培养,通过对成胚条件的系统研究,从‘7447’和‘Poinsett97’中获得了子叶形胚和再生植株。研究结果表明:基因型和小孢子发育时期是限制黄瓜游离小孢子成胚的关键因子。不同品种间胚状体产量差异显著,每皿产胚1.5~33.4个。单核靠边期是进行黄瓜游离小孢子培养的最佳时期。低温预处理有利于胚状体的诱导,4℃预处理2~4d为宜,以处理2d的胚状体产量最高。外源激素在诱导胚状体时并非必需,但低浓度外源激素(0.5mg.L-12,4-D、0.2mg.L-16-BA)能促进小孢子成胚。NLN和B5两种基础培养基在诱导胚状体上无显著差异。子叶形胚易分化成苗,而其它类型的胚状体未能获得再生植株。 | 詹艳 陈劲枫 Ahmed Abbas Malik | 2009 | 园艺学报2009,36,2: | 25 |
| 3 | Role of liver transplantation in the management of hepatoblastoma in the pediatric population显示文摘Hepatoblastoma(HB) is the most common primary liver tumor in children and accounts for two-thirds of all malignant liver neoplasms in the pediatric population. For patients with advanced HB(unresectable or unresponsive to chemotherapy), combined treatment with chemotherapy and liver transplantation is an excellent option. The etiology of HB is mostly obscure because of its extreme rarity although some inherited syndromes and very low birth weight have been associated with it. The prognosis for children with HB has significantly improved in the past three decades thanks to advancements in chemotherapy, surgical resection and postoperative care. In 2002 a surgical staging system called pretreatment extent of disease(PRETEXT) was designed to allow a universal, multidisciplinary approach to patients with HB. Between one-third to two-thirds of patients initially present with unresectable tumors or distant metastases, but up to 85% of these tumors become operable after neoadjuvant chemotherapy. Patients with PRETEXT categories 1, 2, and some 3 are referred for neoadjuvant chemotherapy followed by surgical resection with the goal of complete tumor removal. Classic treatments regimens include a combination of cisplatin, fluorouracil, and vincristine or cisplatin and doxorubicin. Liver transplantation is the only treatment option for unresectable HB. In 2010 the pediatric end-stage liver disease, a pediatric-specific scoring system that determines a patient's ranking on the liver transplant list, began to award additional 'exception' points for patients with HB. We analyzed the Standard Transplant Analysis and Research dataset to assess the impact of changes in exception point criteria for HB on outcomes after liver transplantation at Texas Children's Hospital in Houston, Texas. We found that patients who were listed for transplantation with current HB exception criteria experienced a shorter waitlist time but survival was similar between the two eras. | Saira Khaderi Jacfranz Guiteau Ronald T Cotton Christine O'Mahony Abbas Rana John A Goss | 2014 | World Journal of Transplantation2014,4,4: | 23 |

| 5 | 硬实时系统中基于软件容错的动态调度算法显示文摘在硬实时系统中,由于任务超时完成将会导致灾难性后果,因而硬实时系统具有严格的时间及可靠性限制条件.目前实时容错调度算法大部分针对硬件的容错,很少考虑软件运行的故障.提出了两种类似EDF(earliest deadline first)的软件容错的动态实时调度算法:PKSA(probing K-step algorithm)和CUBA(changing utilization-based algorithm).两种算法在任务执行过程中,通过若干试探性检测步骤,提高了任务可执行性的预测,尽可能地避免了任务早期的失败对后续任务的影响,因此提高了任务的完成率,同时也有效地减少了浪费的CPU时间片数量.通过实验测试,与目前所知的同类算法相比,具有更佳的调度性能——调度成本平衡性. | 李庆华 韩建军 Abbas A Essa 张薇 | 2005 | 软件学报2005,16,1: | 18 |
| 6 | Diagnostic dilemma of abdominal tuberculosis in non-HIV patients:An ongoing challenge for physicians显示文摘AIM: To assess the clinical features, yield of the diagnostic tests and outcome of abdominal tuberculosis in non-HIV patients. METHODS: Adult patients with discharge diagnosis of abdominal tuberculosis (based upon; positive microbiology, histo-pathology, imaging or response to trial of anti TB drugs) during the period 1999 to 2004 were analyzed. Patient’s characteristics, laboratory investigations, radiological, endoscopic and surgical findings were evaluated. Abdominal site involved (intestinal, peritoneal, visceral, and nodal) and response to treatment was also noted. RESULTS: There were 209 patients enrolled. One hundred and twenty-three (59%) were females. Symptoms were abdominal pain 194 (93%), fever 134 (64%), night sweats 99 (48%), weight loss 98 (47%), vomiting 75 (36%), ascites 74 (35%), constipation 64 (31%), and diarrhea 25 (12%). Sub-acute and acute intestinal obstruction was seen in 28 (13%) and 12 (11%) respectively. Radiological evidence of pulmonary tuberculosis was found in 134 (64%) patients. Basis of diagnosis of abdominal tuberculosis were radiology (Chest and barium X-Rays, Ultrasound and CT scan abdomen) in 111 (53%) and histo-pathology (tissue obtained during surgery, colonoscopy, CT or ultrasound guided biopsy, laparoscopy and upper gastro intestinal endoscopy) in 87 (42%) patients. Mycobacterium culture was positive in 6/87 (7%) patients and response to therapeutic trial of anti tubercular drugs was the basis of diagnosis in 5 (2.3%) patients. Predominant site of involvement by abdominal TB was intestinal in 103 (49%) patients, peritoneal in 87 (42%) patients, solid viscera in 10 (5%) and nodal in 9 (4%) patients. Response to medical treatment was found in 158 (76%) patients andadditionally 35 (17%) patients also underwent surgery. In a 425 ± 120 d follow-up period 12 patients died (eight post operative) and no case of relapse was noted. CONCLUSION: Abdominal TB has diverse and non- specific symptomatology. No single test is adequate for diagnosis of abdominal tuberculosis in all patients. Abdominal TB in non-HIV patients remains an ongoing diagnostic dilemma requiring a high index of clinical suspicion. | Rustam Khan Shahab Abid Wasim Jafri Zaigham Abbas Khalid Hameed Zubair Ahmad | 2006 | World Journal of Gastroenterology2006,12,39: | 17 |
| 7 | Histological and biochemical alterations in early-stage lobar ischemia-reperfusion in rat liver显示文摘AIM:To investigate the structural and biochemical changes in the early stage of reperfusion in the rat livers exposed to lobar ischemia-reperfusion (IR).METHODS: The median and left lobes of the liver were subjected to 60 min ischemia followed by 5, 10, 30, 45, 60 and 120 min reperfusion. Blood samples were taken at different time intervals to test enzyme activities and biochemical alterations induced by reperfusion. At the end of each reperfusion period, the animals were killed by euthanasia and tissue samples were taken for histological examination and immunohistochemistry. RESULTS: Cell vacuolation, bleb formation and focal hepatitis were the most important changes occur during ischemia. While some changes including bleb formation were removed during reperfusion, other alterations including portal hepatitis, inflammation and the induction of apoptosis were seen during this stage. The occurrence of apoptosis, as demonstrated by apoptotic cells and bodies, was the most important histological change during reperfusion. The severity of apoptosis was dependent on the time of reperfusion, and by increasing the time of reperfusion,the numbers of apoptotic bodies was significantly enhanced. The amounts of lactate dehydrogenase, alanine aminotransferase, aspartate aminotransferase, creatinine and urea were significantly increased in serum obtained from animals exposed to hepatic IR.CONCLUSION: Inflammation and subsequent apoptotic cell death were the most important changes in early-stage hepatic reperfusion injury, and the number of apoptotic bodies increased with time of reperfusion. | Hossein Ali Arab Farhang Sasani Mohammad Hossein Rafiee Ahmad Fatemi Abbas Javaheri | 2009 | World Journal of Gastroenterology2009,15,16: | 16 |
| 8 | Sustainable development and geospatial information:a strategic framework for integrating a global policy agenda into national geospatial capabilities显示文摘The 2030 Agenda for Sustainable Development provides a new global policy to guide the way countries collectively manage and transform the social,economic,and environmental dimensions of people and the planet over the next 15 years.Achieving sustainable development presents all countries and the global policy community with a set of significant development challenges that are almost entirely geographic in nature.Many of the issues impacting sustainable development can be analyzed,modeled,and mapped within a geographic context,which in turn can provide the integrative framework necessary for global collaboration,consensus and evidence-based decision-making.However,and despite significant advances in geospatial information technologies,there is a lack of awareness,understanding and uptake,particular at the policy and decision-making level,of the vital and integrative role of geospatial information and related enabling architectures such as National Spatial Data Infrastructures.This paper reasons that the role of geospatial information in contributing to sustainable development has not adequately been described by either the sustainable development policy practice or by the geospatial professional community.This lack of policy and guidance,with commensurate critical gaps and connection points with national geospatial frameworks,is a visible impediment to developing countries and those most affected by the challenges and need to achieve sustainable development.The global geospatial community now has a unique opportunity to integrate and connect geospatial information into the global development agenda in a more holistic and sustainable manner,specifically in contributing their data resources toward measuring and monitoring the 17 Sustainable Development Goals,and their 169 associated targets,through the global indicator framework that anchors the 2030 Agenda for Sustainable Development.This paper introduces and discusses a new strategic framework for linking a global policy to national geospatial capabilities. | Greg Scott Abbas Rajabifard | 2017 | Geo-Spatial Information Science2017,20,2: | 14 |
| 9 | Serum cholinesterase: A predictive biomarker of hepatic reserves in chronic hepatitis D显示文摘AIM To determine the predictive performance of cholinesterase compared to existing prognostic models in evaluating liver function in patients with chronic hepatitis D.METHODS In an observational, cross-sectional and retrospective study, consecutive patients with hepatitis D cirrhosis were evaluated. Demographic, clinical and laboratory parameters were recorded. Serum cholinesterase levels were correlated with existing scoring models for chronic liver disease and Liver function tests. Receiver operating characteristic(ROC) curves were constructed to find an optimal cholinesterase level predicting ascites, Child Turcotte Pugh(CTP) score ≥ 10, model for end stage liver disease(MELD) score ≥ 15, baseline-event-anticipation(BEA) score for hepatitis D ≥ 5 and the aspartate transaminase to Platelet Ratio Index(APRI) ≥ 1.5. RESULTS This study investigated 233 patients with chronic liver disease due to hepatitis D; 192 were male, median age 42(16-69 years). Fifty patients had ascites and 15 had encephalopathy. One hundred and sixty-seven(71.7%) were in Child class A, 52(22.3%) in Child class B and 14(5.0%) in class C. A MELD score of 15 or more was seen in 24 patients. Cholinesterase levels correlated well with the INR, albumin, CTP score, MELD, MELD sodium, BEA and APRI scores(P < 0.001 each). Area under the ROC curve for ascites, CTP ≥ 10, MELD ≥ 15, BEA ≥ 5, APRI ≥ 1.5 was 0.836, 0.966, 0.913, 0.871 and 0.825 respectively(P < 0.001 each). Cut off values of cholinesterase(IU/L) for predicting ascites, CTP ≥ 10, MELD ≥ 15, BEA ≥ 5 and APRI ≥ 1.5were < 3812, < 2853, < 2829, < 4719 and < 3954 with a sensitivity of 80%, 100%, 91.67%, 82.50%, 58.0% and specificity of 81.97%, 84.79%, 87.56%, 77.06% and 55.64% respectively. CONCLUSION Serum cholinesterase demonstrates promising correlations with serum albumin, INR and CTP, MELD, BEA and APRI scores and is predictive of liver reserves in hepatitis D cirrhosis. | Minaam Abbas Zaigham Abbas | 2017 | World Journal of Hepatology2017,9,22: | 14 |

| 11 | Effects of water content, water type and temperature on the rheological behaviour of slag-cement and fly ash-cement paste backfill显示文摘The pumping ability and placement performance of fresh cemented paste backfill(CPB) in underground mined cavities depend on its rheological properties. Hence, it is crucial to understand the rheology of fresh CPB slurry, which is related to CPB mixture design and the temperature underground. This paper presented an experimental study investigating the effects of binder type, content, water chemical properties and content, and temperature, on the rheological properties of CPB material prepared using the tailings of a copper mine in South Australia. Portland cement(PC), a newly released commercially manufactured cement called Minecem(MC) and fly ash(FA) were used as the binders added to the mine tailing materials. Various amounts of two different water types were added to the mixtures in the preparation of backfill material slurry. Six different temperatures ranging from 5 to 60 °C were to investigate the effect of temperature on CPB rheology. Overall, the increasing water content and decreasing temperature lead to lower yield stress. Based on the results obtained from the rheological properties of CPB slurry, it was found that at room temperature(25 °C), with regards to the unconfined compressive strength(UCS) performance, the replacement of 4% PC mixed CPB(28 days UCS 425 k Pa) to 3% MC mixed CPB(28 days UCS 519 k Pa), reduced the slurry yield stress from 210.7 to 178.5 Pa. The results also showed that the chemical composition of water affects the yield stress of CPB slurry and that MC mitigates the negative effect of mine-processed water(MW) and thus lead to improve the rheological properties of the slurry. However, the results suggested that the rheological properties of a mixture using MC is very sensitive to the water volume and temperature change. Therefore, using MC in backfill requires better quality control in slump mixing. | Yue Zhao Abbas Taheri Murat Karakus Zhongwei Chen An Deng | 2020 | International Journal of Mining Science and Technology2020,30,3: | 13 |
| 12 | 同构计算环境中一种快速有效的静态任务调度算法显示文摘快速有效的调度任务是多处理器计算环境中的一个关键问题.目前任务调度算法中刻画任务依赖关系最流行的模型是DAG.在以前的文献中,提出了一种新的更实际、更普遍的TTIG模型及其相应的MATE算法(基于同构计算环境).延伸了TTIG模型,并提出基于同构系统的新的算法及两种启发式方法(GBHA1和GBHA2).GBHA以组的形式尽量消除图中回路,因而能获得任务图的全局信息,具有更好的调度性能.在模拟实验中,将此算法与MATE和其他同构环境中基于DAG的有效调度算法,在不同测试条件下进行了比较,结果显示GBHA在性能上明显优于MATE,与基于DAG模型的调度算法比较而言,在性能方面各有千秋,但在算法时间复杂度方面具有显著的优势. | 李庆华 韩建军 Abbas A.Essa | 2005 | 计算机研究与发展2005,42,1: | 12 |
| 13 | Centrifuge modeling of buried continuous pipelines subjected to normal faulting显示文摘Seismic ground faulting is the greatest hazard for continuous buried pipelines.Over the years,researchers have attempted to understand pipeline behavior mostly via numerical modeling such as the finite element method.The lack of well-documented field case histories of pipeline failure from seismic ground faulting and the cost and complicated facilities needed for full-scale experimental simulation mean that a centrifuge-based method to determine the behavior of pipelines subjected to faulting is best to verify numerical approaches.This paper presents results from three centrifuge tests designed to investigate continuous buried steel pipeline behavior subjected to normal faulting.The experimental setup and procedure are described and the recorded axial and bending strains induced in a pipeline are presented and compared to those obtained via analytical methods.The influence of factors such as faulting offset,burial depth and pipe diameter on the axial and bending strains of pipes and on ground soil failure and pipeline deformation patterns are also investigated.Finally,the tensile rupture of a pipeline due to normal faulting is investigated. | Majid Moradi Mahdi Rojhani Abbas Galandarzadeh Shiro Takada | 2013 | Earthquake Engineering and Engineering Vibration2013,12,1: | 11 |
| 14 | Carbon/carbon supercapacitors显示文摘Supercapacitors, or electrochemical capacitors, are a power storage system applied for harvesting energy and delivering pulses during short periods of time. The commercially available technology is based on charging an electrical double-layer (EDL), and using high surface area carbon electrodes in an organic electrolyte. This review first presents the state-of-the-art on EDL capacitors, with the objective to better understand their operating principles and to improve their performance. In particular, it is shown that capacitance might be enhanced for carbons having subnanometric pores where ions of the electrolyte are distorted and partly desolvated. Then, strategies for using environment friendly aqueous electrolytes are presented. In this case, the capacitance can be enhanced through pseudo-faradaic contributions involving i) surface functional groups on carbons, ii) hydrogen electrosorption, and iii) redox reactions at the electrode/electrolyte interface. The most promising system is based on the use of aqueous alkali sulfate as electrolyte allowing voltages as high as 2 V to be reached, due to the high overpotential for di-hydrogen evolution at the negative electrode. | Elzbieta Frackowiak Qamar Abbas Franois Bguin | 2013 | Journal of Energy Chemistry2013,22,2: | 10 |
| 15 | The reliability of the Australasian Triage Scale:a meta-analysis显示文摘BACKGROUND: Although the Australasian Triage Scale(ATS) has been developed two decades ago, its reliability has not been def ined; therefore, we present a meta-analyis of the reliability of the ATS in order to reveal to what extent the ATS is reliable.DATA SOURCES: Electronic databases were searched to March 2014. The included studies were those that reported samples size, reliability coefficients, and adequate description of the ATS reliability assessment. The guidelines for reporting reliability and agreement studies(GRRAS) were used. Two reviewers independently examined abstracts and extracted data. The effect size was obtained by the z-transformation of reliability coefficients. Data were pooled with random-effects models, and meta-regression was done based on the method of moment's estimator.RESULTS: Six studies were included in this study at last. Pooled coefficient for the ATS was substantial 0.428(95%CI 0.340–0.509). The rate of mis-triage was less than fifty percent. The agreement upon the adult version is higher than the pediatric version.CONCLUSION: The ATS has shown an acceptable level of overall reliability in the emergency department, but it needs more development to reach an almost perfect agreement. | Mohsen Ebrahimi Abbas Heydari Reza Mazlom Amir Mirhaghi | 2015 | World Journal of Emergency Medicine2015,6,2: | 10 |
| 16 | Modeling and experimental validation of heat transfer and energy consumption in an innovative greenhouse structure显示文摘The commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times more than free land cultivation but the use of fossil fuels in this production field is very high.The objectives of this paper are to modeling and experimental evaluation of heat and mass transfer functions in an innovative solar greenhouse with thermal screen.For this propose,a semi-solar greenhouse was designed and constructed at the North-West of Iran in Azerbaijan Province(38100N and 46180E with elevation of 1364 m above the sea level).The inside environment factors include inside air temperature below screen(Ta),inside air temperature above screen(Tas),crop temperature(Tc),inside soil temperature(Ts),cover temperature(Tri)and thermal screen temperature(Tsc)were collected as the experimental data samples.The dynamic heat and mass transfer model used to estimate the temperature in six different points of the semi-solar greenhouse with initial values and consider the crop evapotranspiration.The results showed that dynamic model can predict the inside temperatures in four different points(Ta,Tc,Tri,Ts)with MAPE,RMSE and EF about 5-7%,1-2℃ and 80-91%for greenhouse without thermal screen and about 3-7%,0.6-1.8C and 89-96%for six different points of greenhouse with thermal screen(Ta,Tc,Tri,Ts,Tas,Tsc),respectively.The results of using thermal screen at night(12 h)in autumn showed that this method can decrease the use of fossil fuels up to 58%and so decrease the final cost and air pollution.This movable insulation caused about 15℃ difference between outside and inside air temperature and also made about 6℃ difference between Ta and Tas.The experimental results showed that inside thermal screen can decrease the crop temperature fluctuation at night. | Morteza Taki Yahya Ajabshirchi Seyed Faramarz Ranjbar Abbas Rohani Mansour Matloobi | 2016 | Information Processing in Agriculture2016,3,3: | 10 |
| 17 | Somatic embryogenesis in wild relatives of cotton (Gossypium Spp.)显示文摘Wild cotton species can contribute a valuable gene pool for agronomically desirable cultivated tetraploid cultivars. In order to exploit diploid cotton a regeneration system is required to achieve transformation based goals. The present studies aimed at optimizing the conditions for regeneration of local varieties as well as wild species of cotton. Different callus induction media were tested with varying concentrations of hormones in which sucrose was used as nutritional source. Different explants (hypo-cotyls, cotyledon, root) were used to check the regeneration of both local cotton plants and wild relatives using T & G medium, BAP medium, CIM medium, EMMS medium, and cell suspension medium. Different stages of embryogenicity such as early torpedo stage, late torpedo stage, heart stage, globular stage and cotyledonary stage were observed in wild relatives of cotton. The results of this study pave the way for establishing future transformation methods. | RAO Abdul Qayyum HUSSAIN S. Sarfraz SHAHZAD M. Saqib BOKHARI S. Yassir Abbas RAZA M.

| 20 | Recent Advances in Interface Engineering for Electrocatalytic CO_(2) Reduction Reaction显示文摘Electrocatalytic CO_(2) reduction reaction(CO_(2) RR) can store and transform the intermittent renewable energy in the form of chemical energy for industrial production of chemicals and fuels,which can dramatically reduce CO_(2) emission and contribute to carbon-neutral cycle. E cient electrocatalytic reduction of chemically inert CO_(2) is challenging from thermodynamic and kinetic points of view. Therefore,low-cost,highly e cient,and readily available electrocatalysts have been the focus for promoting the conversion of CO_(2). Very recently,interface engineering has been considered as a highly e ective strategy to modulate the electrocatalytic performance through electronic and/or structural modulation,regulations of electron/proton/mass/intermediates,and the control of local reactant concentration,thereby achieving desirable reaction pathway,inhibiting competing hydrogen generation,breaking binding-energy scaling relations of intermediates,and promoting CO_(2) mass transfer. In this review,we aim to provide a comprehensive overview of current developments in interface engineering for CO_(2) RR from both a theoretical and experimental stand-point,involving interfaces between metal and metal,metal and metal oxide,metal and nonmetal,metal oxide and metal oxide,organic molecules and inorganic materials,electrode and electrolyte,molecular catalysts and electrode,etc. Finally,the opportunities and challenges of interface engineering for CO_(2) RR are proposed. | Junjun Li Sulaiman Umar Abbas Haiqing Wang Zhicheng Zhang Wenping Hu | 2021 | Nano-Micro Letters2021,13,12: | 9 |
