| 3 | Aqueous extracts of microalgae exhibit antioxidant and anticancer activities显示文摘Objective:To investigate the antioxidant and anticancer activities of aqueous extracts of nine microalgal species.Methods:Variable percentages of major secondary metabolites(total phenolic content,terpenoids and alkaloids) as well as phycobiliprotein pigments(phycocyanin, allophycocyanin and phycoerythrin) in the aqueous algal extracts were recorded.Antioxidant activity of the algal extracts was performed using 2,2 diphenyl-1-picrylhydrazyl(DPPH) test and 2,2'azino-bis(ethylbenzthiazoline-6-sulfonic acid(ABTS.) radical cation assay.Anticancer efficiency of the algal water extracts was investigated against Ehrlich Ascites Carcinoma cell(EACC) and Human hepatocellular cancer cell line(HepG2).Results:Antioxidant activity of the algal extracts was performed using DPPH test and ABTS.^+ radical cation assays which revealed 30.1-72.4%and 32.0-75.9%respectively.Anticancer efficiency of the algal water extracts was investigated against Ehdich Ascites Carcinoma Cell(EACC) and Human Hepatocellular cancer cell line(HepG2) with an activity ranged 87.25%and 89.4%respectively.Culturing the promising cyanobacteria species;Nostoc muscorum and Oscillatoria sp.under nitrogen stress conditions(increasing and decreasing nitrate content of the normal BG11 medium,1.5 g/L),increased nitrate concentration(3,6 and 9 g/L) led to a remarkable increase in phycobilin pigments followed by an increase in both antioxidant and anticancer activities in both cyanobacterial species.While the decreased nitrate concentration(0.75,0.37 and 0.0 g/L) induced an obvious decrease in phycobilin pigments with complete absence of allophycocyanin in case of Oscillatoria sp.Conclusions:Nitrogen starvation(0.00 g/L nitrate) induced an increase and comparable antioxidant and anticancer activities to those cultured in the highest nitrate content. | Sanaa MM Shanab Soha SM Mostafa Emad A Shalaby Ghada I Mahmoud | 2012 | Asian Pacific Journal of Tropical Biomedicine2012,2,8: | 6 |
| 4 | Over-mature beech trees (Fagus orientalis Lipsky) and close-to-nature forestry in northern Iran显示文摘Oriental Beech is the most important commercial tree species in northern Iran. In recent years wood production companies interested in felling large beech trees for profit have challenged advocates of close-to-nature silviculture who favor conservation. Our study objective was to assess the economic value of over-mature beech trees by relating tree diameter (DBH) to amount of decay. Based on the location of onset of decay, we categorized three types of decay as stump, stem, and crown decay. Trees of greater diameter (age) typically showed greater decay in the stem. Percent of decayed volume, diameter of decayed tissue, and length of decay in tree stems varied between 0.5%?64.3%, 15 cm?75 cm, and 2.0?19.5 m, respectively. With increasing trunk diameter, the proportion of truck decay increased. Red heart and dark red heart constituted 25% and 14.3% of sampled trees, respectively. However, we found no correlation between intensity of stem decay and morphological characteristics of trees. Seedlings were not abundant around the bases of over-mature trees, suggesting that the trees did not contribute to regeneration of the stand. Beech trees of diameter >1 m do not provide valuable round wood for industries and cause to raise wood production costs. We recommend that these trees >1 m DBH should be retained in forest stands because of their low commercial value but high ecological and conservational values such as maintaining biodiversity in forest ecosys-tems. | Mostafa Moradi Mohammad R.Marvie Mohadjer Kiomars Sefidi Mahmoud Zobiri Ali Omidi | 2012 | Journal of Forestry Research2012,23,2: | 5 |
| 5 | Asymptomatic seminal infection of herpes simplex virus:impact on male infertility显示文摘In more than half of infertile men,the cause of their infertility is unknown.Several studies revealed the role of viral infections in male infertility.The aim of the present study was to determine the prevalence of herpes simplex virus-1 (HSV-1) and HSV-2 in semen from asymptomatic infertile male patients,and its association with altered semen parameters.A total of 70 semen samples were collected from infertile men who attended the Research and Clinical Center for Infertility in Yazd,Iran.Semen analysis and diagnostic real-time PCR using specific primers and probes for HSV-1 and HSV-2 DNA were performed.Comparison of semen parameters between virally infected and non-infected samples were performed with independent t-test and Mann-Whitney test.Semen analysis showed that infertile men fell into two groups,the male factor group and the unexplained group.HSV-1 and HSV-2 DNA was detected in 16 (22.9%) and 10 (14.3%) of 70 semen samples,respectively.All HSV-positive samples had abnormal semen parameters (the male factor group).Although HSV infection was not associated with sperm motility and morphological defects,it was correlated with lower sperm count in the seminal fluid.The findings suggest that asymptomatic seminal infection of HSV plays an important role in male infertility by adversely affecting sperm count. | Seyed Hamidreza Monavari Mostafa Salehi vaziri Mohammadali Khalili Mahmoud Shamsi-Shahrabadi Hossein Keyvani Hamidreza Mollaei Mehdi Fazlalipour | 2013 | The Journal of Biomedical Research2013,27,1: | 4 |

| 11 | Current systematic reviews and meta-analyses of COVID-19显示文摘BACKGROUND Coronavirus disease 2019(COVID-19)has left a significant impact on the world's health,economic and political systems;as of November 20,2020,more than 57 million people have been infected worldwide,with over 1.3 million deaths.While the global spotlight is currently focused on combating this pandemic through means ranging from finding a treatment among existing therapeutic agents to inventing a vaccine that can aid in halting the further loss of life.AIM To collect all systematic reviews and meta-analyses published related to COVID-19 to better identify available evidence,highlight gaps in knowledge,and elucidate further meta-analyses and umbrella reviews that are yet to be performed.METHODS We explored studies based on systematic reviews and meta-analyses with the keyterms,including severe acute respiratory syndrome(SARS),SARS virus,coronavirus disease,COVID-19,and SARS coronavirus-2.The included studies were extracted from Embase,Medline,and Cochrane databases.The publication timeframe of included studies ranged between January 01,2020,to October 30,2020.Studies that were published in languages other than English were not considered for this systematic review.The finalized full-text articles are freely accessible in the public domain.RESULTS Searching Embase,Medline,and Cochrane databases resulted in 1906,669,and 19 results,respectively,that comprised 2594 studies.515 duplicates were subsequently removed,leaving 2079 studies.The inclusion criteria were systematic reviews or meta-analyses.860 results were excluded for being a review article,scope review,rapid review,panel review,or guideline that produced a total of 1219 studies.After screening articles were categorized,the included articles were put into main groups of clinical presentation,epi-demiology,screening and diagnosis,severity assessment,special populations,and treatment.Subsequently,there was a second subclassification into the following groups:gastrointestinal,cardiovascular,neurological,stroke,thrombosis,anosmia and dysgeusia,ocular manifestations,nephrology,cutaneous manifestations,D-dimer,lymphocyte,anticoagulation,antivirals,convalescent plasma,immunosuppressants,corticosteroids,hydroxychloroquine,renin-angiotensin-aldosterone system,technology,diabetes mellitus,obesity,pregnancy,children,mental health,smoking,cancer,and transplant.CONCLUSION Among the included articles,it is clear that further research is needed regarding treatment options and vaccines.With more studies,data will be less heterogeneous,and statistical analysis can be better applied to provide more robust clinical evidence.This study was not designed to give recommendations regarding the management of COVID-19. | Mahmoud Nassar Nso Nso Mostafa Alfishawy Anastasia Novikov Salim Yaghi Luis Medina Bahtiyar Toz Sofia Lakhdar Zarwa Idrees Yungmin Kim Dawa Ongyal Gurung Raheel S Siddiqui David Zheng Mariam Agladze Vikram Sumbly Jasmine Sandhu Francisco Cuevas Castillo Nadya Chowdhury Ravali Kondaveeti Sakil Bhuiyan Laura Guzman Perez Riki Ranat Carlos Gonzalez Harangad Bhangoo John Williams Alaa Eldin Osman Joyce Kong Jonathan Ariyaratnam Mahmoud Mohamed Ismail Omran Mariely Lopez Akwe Nyabera Ian Landry Saba Iqbal Anoosh Zafar Gondal Sameen Hassan Ahmed Daoud Bahaaeldin Baraka Theo Trandafirescu Vincent Rizzo | 2021 | World Journal of Virology2021,10,4: | 2 |
| 12 | Capacitor Voltage Balancing Strategy Based on Sub-module Capacitor Voltage Estimation for Modular Multilevel Converters显示文摘The modular multilevel converter(MMC)is expected to be used extensively in high-voltage direct current(HVDC)transmission networks because of its superior characteristics over the line-commutated converter(LCC).A key issue of concern is balancing sub-module capacitor voltages in the MMCs,which is critical for the correct operation of these converters.The majority of voltage balancing techniques proposed thus far require that the measurement of the capacitor voltages use a reliable measuring system.This can increase the capital cost of the converters.This paper presents a voltage balancing strategy based on capacitor voltage estimation using the adaptive linear neuron(ADALINE)algorithm.The proposed estimation unit requires only three voltage sensors per phase for the arm reactors and the output phase voltages.Measurements of sub-module capacitor voltages and associated communication links with the central controller are not needed.The proposed strategy can be applied to MMC systems that contain a large number of sub-modules.The method uses PSCAD/EMTDC,with particular focus on dynamic performance under a variety of operating conditions. | Mahmoud Abdelsalam Mostafa Marei Sarath Tennakoon Alison Griffiths | 2016 | CSEE Journal of Power and Energy Systems2016,2,1: | 2 |
| 13 | COVID-19 and hepatic injury: cellular and molecular mechanisms in diverse liver cells显示文摘The coronavirus disease 2019(COVID-19)represents a global health and economic challenge.Hepatic injuries have been approved to be associated with severe acute respiratory syndrome coronavirus(SARS-CoV-2)infection.The viral tropism pattern of SARS-CoV-2 can induce hepatic injuries either by itself or by worsening the conditions of patients with hepatic diseases.Besides,other factors have been reported to play a crucial role in the pathological forms of hepatic injuries induced by SARS-CoV-2,including cytokine storm,hypoxia,endothelial cells,and even some treatments for COVID-19.On the other hand,several groups of people could be at risk of hepatic COVID-19 complications,such as pregnant women and neonates.The present review outlines and discusses the interplay between SARS-CoV-2 infection and hepatic injury,hepatic illness comorbidity,and risk factors.Besides,it is focused on the vaccination process and the role of developed vac-cines in preventing hepatic injuries due to SARS-CoV-2 infection. | Fares E M Ali Mostafa K Abd El-Aziz Mahmoud M Ali Osama M Ghogar Adel G Bakr | 2023 | World Journal of Gastroenterology2023,29,3: | 2 |
| 14 | Early detection of hepatocellular carcinoma co-occurring with hepatitis C virus infection: A mathematical model显示文摘AIM: To develop a mathematical model for the early detection of hepatocellular carcinoma(HCC) with a panel of serum proteins in combination with α-fetoprotein(AFP).METHODS: Serum levels of interleukin(IL)-8, soluble intercellular adhesion molecule-1(s ICAM-1), soluble tumor necrosis factor receptor Ⅱ(s TNF-RⅡ), proteasome, and β-catenin were measured in 479 subjects categorized into four groups:(1) HCC concurrent with hepatitis C virus(HCV) infection(n = 192);(2) HCV related liver cirrhosis(LC)(n = 96);(3) Chronic hepatitis C(CHC)(n = 96); and(4) Healthy controls(n = 95). The R package and different modules for binary and multi-class classifiers based on generalized linear models were used to model the data. Predictive power was used to evaluate the performance of the model. Receiver operating characteristic curve analysis over pairs of groups was used to identify the best cutoffs differentiating the different groups. RESULTS: We revealed mathematical models, based on a binary classifier, made up of a unique panel of serum proteins that improved the individual performance of AFP in discriminating HCC patients from patients with chronic liver disease either with or without cirrhosis. We discriminated the HCC group from the cirrhotic liver group using a mathematical model(-11.3 + 7.38 × Prot + 0.00108 × s ICAM + 0.2574 ×β-catenin + 0.01597 × AFP) with a cutoff of 0.6552, which achieved 98.8% specificity and 89.1% sensitivity. For the discrimination of the HCC group from the CHC group, we used a mathematical model [-10.40 + 1.416 × proteasome + 0.002024 × IL + 0.004096 × s ICAM-1 +(4.251 × 10-4) × s TNF + 0.02567 ×β-catenin + 0.02442 × AFP] with a cutoff 0.744 and achieved 96.8% specificity and 89.7% sensitivity. Additionally, we derived an algorithm, based on a binary classifier, for resolving the multi-class classification problem by using three successive mathematical model predictions of liver disease status. CONCLUSION: Our proposed mathematical model may be a useful method for the early detection of different statuses of liver disease co-occurring with HCV infection. | Abdel-Rahman Nabawy Zekri Amira Salah El-Din Youssef Yasser Mabrouk Bakr Reham Mohamed Gabr Ola Sayed Ahmed Mostafa Hamed Elberry Ahmed Mahmoud Mayla Mohamed Abouelhoda Abeer A Bahnassy | 2016 | World Journal of Gastroenterology2016,22,16: | 2 |

| 18 | Analysis of Twitter Data Using Evolutionary Clustering during the COVID-19 Pandemic显示文摘People started posting textual tweets on Twitter as soon as the novel coronavirus(COVID-19)emerged.Analyzing these tweets can assist institutions in better decision-making and prioritizing their tasks.Therefore,this study aimed to analyze 43 million tweets collected between March 22 and March 30,2020 and describe the trend of public attention given to the topics related to the COVID-19 epidemic using evolutionary clustering analysis.The results indicated that unigram terms were trended more frequently than bigram and trigram terms.A large number of tweets about the COVID-19 were disseminated and received widespread public attention during the epidemic.The high-frequency words such as“death”,“test”,“spread”,and“lockdown”suggest that people fear of being infected,and those who got infection are afraid of death.The results also showed that people agreed to stay at home due to the fear of the spread,and they were calling for social distancing since they become aware of the COVID-19.It can be suggested that social media posts may affect human psychology and behavior.These results may help governments and health organizations to better understand the psychology of the public,and thereby,better communicate with them to prevent and manage the panic. | Ibrahim Arpaci Shadi Alshehabi Mostafa Al-Emran Mahmoud Khasawneh Ibrahim Mahariq Thabet Abdeljawad Aboul Ella Hassanien | 2020 | Computers, Materials & Continua2020,,10: | 1 |
| 19 | An agent-based simulation with NetLogo platform to evaluate forward osmosis process(PRO Mode)显示文摘Forward osmosis(FO), as an emerging technology, is influenced by different factors such as operating conditions,module characteristics, and membrane properties. The general aim of this study was to develop a suitable(flexible,comprehensive, and convenient to use) computational tool which is able to simulate osmosis through an asymmetric membrane oriented in pressure retarded osmosis(PRO) mode in a wide variety of scenarios. For this purpose, an agent-based model was created in NetLogo platform, which is an easy-to-use application environment with graphical visualization abilities and well suited for modeling a complex system evolving over time. The simulation results were validated with empirical data obtained from literature and a great agreement was observed. The effect of various parameters on process performance was investigated in terms of temperature,cross-flow velocity, length of the module, pure water permeability coefficient, and structural parameter of the membrane. Results demonstrated that the increase in all parameters, except structural parameter of the membrane and the length of module led to the increase of average water flux. Moreover, nine different draw solutes were selected in order to assess the influence of net bulk osmotic pressure difference between the draw solution(DS) and feed solution(FS)(known as the driving force of FO process) on water flux. Based on the findings of this paper, the performance of FO process(PRO mode) can be efficiently evaluated using the NetL ogo platform. | Mostafa Taherian Seyed Mahmoud Mousavi Hooman Chamani | 2018 | Chinese Journal of Chemical Engineering2018,26,12: | 1 |
