| 1 | Acute-on-chronic liver failure:recent update显示文摘Acute on chronic liver failure(ACLF) was first described in 1995 as a clinical syndrome distinct to classic acute decompensation.Characterized by complications of decompensation,ACLF occurs on a background of chronic liver dysfunction and is associated with high rates of organ failure and significant short-term mortality estimated between45%and 90%.Despite the clinical relevance of the condition,it still remains largely undefined with continued disagreement regarding its precise etiological factors,clinical course,prognostic criteria and management pathways.It is concerning that,despite our relative lack of understanding of the condition,the burden of ACLF among cirrhotic patients remains significant with an estimated prevalence of 30.9%.This paper highlights our current understanding of ACLF,including its etiology,diagnostic and prognostic criteria and pathophysiology.It is evident that further refinement of the ACLF classification system is required in order to detect high-risk patients and improve short-term mortality rates.The field of metabolomics certainly warrants investigation to enhance diagnostic and prognostic parameters,while the use of granulocyte-colony stimulating factor is a promising future therapeutic intervention for patients with ACLF. | Azeem Alam Ka Chun Suen Daqing Ma | 2017 | The Journal of Biomedical Research2017,31,4: | 16 |
| 2 | Current technology development for CO2 utilization into solar fuels and chemicals:A review显示文摘The continuous consumption of fossil fuels causes two important impediments including emission of large concentrations of CO2 resulting in global warming and alarming utilization of energy assets.The conversion of greenhouse gas CO2 into solar fuels can be an expedient accomplishment for the solution of both problems,all together.CO2 reutilization into valuable fuels and chemicals is a great challenge of the current century.Owing to limitations in traditional approaches,there have been developed many novel technologies such as photochemical,biochemical,electrochemical,plasma-chemical and solar thermochemical.They are currently being used for CO2 capture,sequestration,and utilization to transform CO2 into valuable products such as syngas,methane,methanol,formic acid,as well as fossil fuel consumption reduction.This review summarizes different traditional and novel thermal technologies used in CO2 conversion with detailed information about their working principle,types,currently adopted methods,developments,conversion rates,products formed,catalysts and operating conditions.Moreover,a comparison of these novel technologies in terms of distinctive key features such as conversion rate,yield,use of earth metals,renewable energy,investment,and operating cost has been provided in order to have a useful review for future research direction. | Azeem Mustafa Bachirou Guene Lougou Yong Shuai Zhijiang Wang Heping Tan | 2020 | Journal of Energy Chemistry2020,29,10: | 16 |

| 5 | Therapeutic options for the management of pancreatic cancer显示文摘Since its initial characterization, pancreatic ductal adenocarcinoma has remained one of the most devastating and difficult cancers to treat. Pancreatic cancer is the fourth leading cause of death in the United States, resulting in an estimated 38460 deaths annually. With few screening tools available to detect this disease at an early stage, 94% of patients will die within five years of diagnosis. Despite decades of research that have led to a better understanding of the molecular and cellular signaling pathways in pancreatic cancer cells, few effective therapies have been developed to target these pathways. Other treatment options have included more sophisticated pancreatic cancer surgeries and combination therapies. While outcomes have improved modestly for these patients, more effective treatmentsare desperately needed. One of the greatest challenges in the future of treating this malignancy will be to develop therapies that target the tumor microenvironment and surrounding pancreatic cancer stem cells in addition to pancreatic cancer cells. Recent advances in targeting pancreatic stellate cells and the stroma have encouraged researchers to shift their focus to the role of desmoplasia in pancreatic cancer pathobiology in the hopes of developing newer-generation therapies. By combining novel agents with current cytotoxic chemotherapies and radiation therapy and personalizing them to each patient based on specific biomarkers, the goal of prolonging a patient's life could be achieved. Here we review the most effective therapies that have been used for the treatment of pancreatic cancer and discuss the future potential of therapeutic options. | Maria L Rossi Azeem A Rehman Christopher S Gondi | 2014 | World Journal of Gastroenterology2014,20,32: | 13 |
| 6 | Computed tomography overestimation of esophageal tumor length: Implications for radiotherapy planning显示文摘AIM:To assess the relationship between preoperative computed tomography(CT)and postoperative pathological measurements of esophageal tumor length and the prognostic significance of CT tumor length data.METHODS:A retrospective study was carried out in 56 patients who underwent curative esophagogastrectomy.Tumor lengths were measured on the immediate preoperative CT and on the post-operative resection specimens.Inter-and intra-observer variations in CT measurements were assessed.Survival data were collected.RESULTS:There was a weak correlation between CT and pathological tumor length(r=0.30,P=0.025).CT lengths were longer than pathological lengths in 68%(38/56)of patients with a mean difference of 1.67 cm(95%CI:1.18-2.97).The mean difference in measurements by two radiologists was 0.39 cm(95% CI:-0.59-1.44).The mean difference between repeat CT measured tumor length(intra-observer variation) were 0.04 cm(95%CI:-0.59-0.66)and 0.47 cm (95%CI:-0.53-1.47).When stratified,patients not receiving neoadjuvant chemotherapy showed a strong correlation between CT and pathological tumor length(r =0.69,P=0.0014,n=37)than patients that did(r= 0.13,P=0.43,n=19).Median survival with CT tumor length>5.6 cm was poorer than with smaller tumors,but the difference was not statistically significant.CONCLUSION:Esophageal tumor length assessed using CT does not reflect pathological tumor extent and should not be the only modality used for management decisions,particularly for planning radiotherapy. | Karim Sillah Luke R Williams Hans-Ulrich Laasch Azeem Saleem Gillian Watkins Susan A Pritchard Patricia M Price Catharine M West Ian M Welch | 2010 | World Journal of Gastrointestinal Oncology2010,2,4: | 10 |
| 7 | Early repolarization syndrome: A cause of sudden cardiac death显示文摘Early repolarization syndrome(ERS), demonstrated as J-point elevation on an electrocardiograph, was formerly thought to be a benign entity, but the recent studies have demonstrated that it can be linked to a considerable risk of life- threatening arrhythmias and sudden cardiac death(SCD). Early repolarization characteristics associated with SCD include high-amplitude J-point elevation, horizontal and/or downslopping ST segments, and inferior and/or lateral leads location. The prevalence of ERS varies between 3% and 24%, depending on age, sex and J-point elevation(0.05 m V vs 0.1 m V) being the main determinants.ERS patients are sporadic and they are at a higher risk of having recurrent cardiac events. Implantable cardioverter-defibrillator implantation and isoproterenol are the suggested therapies in this set of patients. On the other hand, asymptomatic patients with ERS are common and have a better prognosis. The risk stratification in asymptomatic patients with ERS still remains a grey area. This review provides an outline of the up-to-date evidence associated with ERS and the risk of life- threatening arrhythmias. Further prospective studies are required to elucidate the mechanisms of ventricular arrhythmogenesis in patients with ERS. | Abdi Ali Nida Butt Azeem S Sheikh | 2015 | World Journal of Cardiology2015,7,8: | 9 |
| 8 | Postoperative sleep disorders and their potential impacts on surgical outcomes显示文摘Postoperative sleep disturbance is a common occurrence with significant adverse effects on patients including delayed recovery,impairment of cognitive function,pain sensitivity and cardiovascular events.The development of postoperative sleep disturbance is multifactorial and involves the surgical inflammatory response,the severity of surgical trauma,pain,anxiety,the use of anesthetics and environmental factors such as nocturnal noise and light levels.Many of these factors can be managed perioperatively to minimize the deleterious impact on sleep.Pharmacological and non-pharmacological treatment strategies for postoperative sleep disturbance include dexmedetomidine,zolpidem,melatonin,enhanced recovery after surgery(ERAS) protocol and controlling of environmental noise and light levels.It is likely that a combination of pharmacological and non-pharmacological therapies will have the greatest impact;however,further research is required before their use can be routinely recommended. | Sanketh Rampes Katie Ma Yasmin Amy Divecha Azeem Alam Daqing Ma | 2020 | The Journal of Biomedical Research2020,34,4: | 9 |

| 10 | 沼液过量还田对土壤环境容量及玉米生长的影响显示文摘以沼液过量还田为前提,探讨沼液不同还田量对土壤环境质量和玉米生长发育的影响,提出沼液还田的安全容量。根据目标需氮量确定沼液施用量,共设5个处理:未施加任何肥料(N0 t/hm^(2),CK);1倍氮当量沼液(N 0.885 t/hm^(2),1N);2倍氮当量沼液(N 1.770 t/hm^(2),2N);3倍氮当量沼液(N 2.655 t/hm^(2),3N);4倍氮当量沼液(N 3.540 t/hm^(2),4N)。结果表明,沼液还田可显著增加玉米田土壤中Cu、Zn含量,1N处理为最佳安全容量,2N、3N、4N处理土壤存在Cu、Zn污染风险,其中,玉米完熟时4N处理Cu、Zn含量分别超出风险筛选值10.96%和10.36%,风险最大。与对照相比,沼液还田显著增加玉米苗期土壤中可溶性盐含量,提高土壤的pH值,但随着生育期的延长,可溶性盐含量和pH值呈下降趋势;至玉米的完熟期,1N、2N、3N、4N处理土壤可溶性盐含量比对照分别高出30.59%、52.16%、72.35%、108.63%,土壤pH值比对照分别高出3.95%、6.41%、9.05%、13.65%。所有处理的蛔虫卵死亡率均为100%,故沼液还田不存在蛔虫卵存活的安全风险,但3N与4N处理土壤存在大肠杆菌污染的风险,完熟期这2个处理土壤的大肠杆菌菌群含量分别为20、30个/g。沼液还田可增加玉米产量和改善玉米品质,以3N处理产量最高和品质最优,与对照相比,粗蛋白、粗脂肪、粗淀粉含量分别提高了19.82%、89.01%、11.31%,产量是对照的2.08倍。综合分析认为,以玉米产量最大和品质最优为优先目标时,3N处理为最优,以土壤环境安全容量为优先目标时,1N处理为最优。 | 李金澄 孙吉翠 杨丽 MUHAMMAD Azeem 张忠兰 杨守军 | 2021 | 河南农业科学2021,50,5: | 8 |
| 11 | Nonlinear joint PP-PS AVO inversion based on improved Bayesian inference and LSSVM显示文摘Multiwave seismic technology promotes the application of joint PP–PS amplitude versus offset (AVO) inversion;however conventional joint PP–PS AVO inversioan is linear based on approximations of the Zoeppritz equations for multiple iterations. Therefore the inversion results of P-wave, S-wave velocity and density exhibit low precision in the faroffset;thus, the joint PP–PS AVO inversion is nonlinear. Herein, we propose a nonlinear joint inversion method based on exact Zoeppritz equations that combines improved Bayesian inference and a least squares support vector machine (LSSVM) to solve the nonlinear inversion problem. The initial parameters of Bayesian inference are optimized via particle swarm optimization (PSO). In improved Bayesian inference, the optimal parameter of the LSSVM is obtained by maximizing the posterior probability of the hyperparameters, thus improving the learning and generalization abilities of LSSVM. Then, an optimal nonlinear LSSVM model that defi nes the relationship between seismic refl ection amplitude and elastic parameters is established to improve the precision of the joint PP–PS AVO inversion. Further, the nonlinear problem of joint inversion can be solved through a single training of the nonlinear inversion model. The results of the synthetic data suggest that the precision of the estimated parameters is higher than that obtained via Bayesian linear inversion with PP-wave data and via approximations of the Zoeppritz equations. In addition, results using synthetic data with added noise show that the proposed method has superior anti-noising properties. Real-world application shows the feasibility and superiority of the proposed method, as compared with Bayesian linear inversion. | Xie Wei Wang Yan-Chun Liu Xue-Qing Bi Chen-Chen Zhang Feng-Qi Fang Yuan Tahir Azeem | 2019 | Applied Geophysics2019,16,1: | 7 |

| 15 | Viral respiratory infections among Hajj pilgrims in 2013显示文摘Middle East respiratory syndrome coronavirus(MERS-Co V) has emerged in the Arabian Gulf region, with its epicentre in Saudi Arabia, the host of the ‘Hajj' which is the world's the largest mass gathering. Transmission of MERS-Co V at such an event could lead to its rapid worldwide dissemination. Therefore, we studied the frequency of viruses causing influenza-like illnesses(ILI) among participants in a randomised controlled trial at the Hajj 2013. We recruited 1038 pilgrims from Saudi Arabia, Australia and Qatar during the first day of Hajj and followed them closely for four days. A nasal swab was collected from each pilgrim who developed ILI. Respiratory viruses were detected using multiplex RT-PCR. ILI occurred in 112/1038(11%) pilgrims. Their mean age was 35 years, 49(44%) were male and 35(31%) had received the influenza vaccine pre-Hajj. Forty two(38%) pilgrims had laboratory-confirmed viral infections; 28(25%) rhinovirus, 5(4%) influenza A, 2(2%) adenovirus, 2(2%) human coronavirus OC43/229 E, 2(2%) parainfluenza virus 3, 1(1%) parainfluenza virus 1, and 2(2%) dual infections. No MERS-Co V was detected in any sample. Rhinovirus was the commonest cause of ILI among Hajj pilgrims in 2013. Infection control and appropriate vaccination are necessary to prevent transmission of respiratory viruses at Hajj and other mass gatherings. | Osamah Barasheed Harunor Rashid Mohammad Alfelali Mohamed Tashani Mohammad Azeem Hamid Bokhary Nadeen Kalantan Jamil Samkari Leon Heron Jen Kok Janette Taylor Haitham El Bashir Ziad A.Memish Elizabeth Haworth Edward C.Holmes Dominic E Dwyer Atif Asghar Robert Booy | 2014 | Virologica Sinica2014,29,6: | 3 |

| 17 | Hepatocellular injury and the mortality risk among patients with COVID-19: A retrospective cohort study显示文摘BACKGROUND Clearly,infection with severe acute respiratory syndrome coronavirus 2 is not limited to the lung but also affects other organs.We need predictive models to determine patients’prognoses and to improve health care resource allocation during the coronavirus disease 2019(COVID-19)pandemic.While treating COVID-19,we observed differential outcome prediction weights for markers of hepatocellular injury among hospitalized patients.AIM To investigate the association between hepatocellular injury and all-cause inhospital mortality among patients with COVID-19.METHODS This multicentre study employed a retrospective cohort design.All adult patients admitted to Al-Azhar University Hospital,Assiut,Egypt and Abo Teeg General Hospital,Assiut,Egypt with confirmed COVID-19 from June 1,2020,to July 30,2020 were eligible.We categorized our cohort into three groups of(1)patients with COVID-19 presenting normal aminotransferase levels;(2)patients with COVID-19 presenting one-fold higher aminotransferase levels;and(3)patients with COVID-19 presenting two-fold higher aminotransferase levels.We analysed the association between elevated aminotransferase levels and all-cause in-hospital mortality.The survival analysis was performed using the Kaplan–Meier method and tested by log-rank analysis.RESULTS In total,376 of 419 patients met the inclusion criteria,while 29(8%)patients in our cohort died during the hospital stay.The median age was 40 years(range:28-56 years),and 51%were males(n=194).At admission,54%of the study cohort had liver injury.The pattern of liver injury was hepatocellular injury with an aspartate aminotransferase(AST)predominance.Admission AST levels were independently associated with all-cause in-hospital mortality in the logistic regression analysis.A one-fold increase in serum AST levels among patients with COVID-19 led to an eleven-fold increase in in-hospital mortality(P<0.001).Admission AST levels correlated with C-reactive protein(r=0.2;P<0.003)and serum ferritin(r=0.2;P<0.0002)levels.Admission alanine aminotransferase levels correlated with serum ferritin levels(r=0.1;P<0.04).Serum total bilirubin levels were independently associated with in-hospital mortality in the binary logistic regression analysis after adjusting for age and sex but lost its statistical significance in the fully adjusted model.Serum ferritin levels were significantly associated with in-hospital mortality(P<0.01).The probability of survival was significantly different between the AST groups and showed the following order:a two-fold increase in AST levels>a one-fold increase in in AST levels>normal AST levels(P<0.0001).CONCLUSION Liver injury with an AST-dominant pattern predicts the severity of COVID-19.Elevated serum ferritin levels are associated with fatal outcomes. | Ali Madian Ahmed Eliwa Hytham Abdalla Haitham A Azeem Aly | 2021 | World Journal of Hepatology2021,13,8: | 3 |
| 18 | QTL Mapping for Adult Plant Resistance to Powdery Mildew in Italian Wheat cv. Strampelli显示文摘The Italian wheat cv.Strampelli displays high resistance to powdery mildew caused by Blumeria graminis f.sp.tritici.The objective of this study was to map quantitative trait loci(QTLs) for resistance to powdery mildew in a population of 249 F 2:3 lines from Strampelli/Huixianhong.Adult plant powdery mildew tests were conducted over 2 yr in Beijing and 1 yr in Anyang and simple sequence repeat(SSR) markers were used for genotyping.QTLs Qpm.caas-3BS,Qpm.caas-5BL.1,and Qpm.caas-7DS were consistent across environments whereas,Qpm.caas-2BS.1 found in two environments,explained 0.4-1.6,5.5-6.9,27.1-34.5,and 1.0-3.5% of the phenotypic variation respectively.Qpm.caas-7DS corresponded to the genomic location of Pm38/Lr34/Yr18.Qpm.caas-4BL was identified in Anyang 2010 and Beijing 2011,accounting for 1.9-3.5% of phenotypic variation.Qpm.caas-2BS.1 and Qpm.caas-5BL.1 contributed by Strampelli and Qpm.caas-3BS by Huixianhong,seem to be new QTL for powdery mildew resistance.Qpm.caas-4BL,Qpm.caas-5BL.3,and Qpm.caas-7DS contributed by Strampelli appeared to be in the same genomic regions as those mapped previously for stripe rust resistance in the same population,indicating that these loci conferred resistance to both stripe rust and powdery mildew.Strampelli could be a valuable genetic resource for improving durable resistance to both powdery mildew and stripe rust in wheat. | Asad Muhammad Azeem BAI Bin LAN Cai-xia YAN Jun XIA Xian-chun ZHANG Yong HE Zhong-hu | 2013 | Journal of Integrative Agriculture2013,12,5: | 3 |
