| 1 | Exact solutions for nonlinear partial fractional differential equations显示文摘In this article,we use the fractional complex transformation to convert nonlinear partial fractional differential equations to nonlinear ordinary differential equations.We use the improved(G'/G)-expansion function method to calculate the exact solutions to the time-and space-fractional derivative foam drainage equation and the time-and space-fractional derivative nonlinear KdV equation.This method is efficient and powerful for solving wide classes of nonlinear evolution fractional order equations. | Khaled A.Gepreel Saleh Omran | 2012 | Chinese Physics B2012，21，11： | 20 |
| 2 | Circulating tumor and cancer stem cells in hepatitis C virusassociated liver disease显示文摘AIM:To assess the role of circulating tumor cells(CTCs)and cancer stem cells(CSCs)in hepatitis C virus(HCV)-associated liver disease.METHODS:Blood and/or tissue samples were obtained from HCV(genotype 4)-associated hepatocellularcarcinoma patients(HCC;n=120),chronic hepatitis C patients(CH;n=30)and 33 normal control subjects(n=33).Serum levels of alpha-fetoprotein(AFP),alkaline phosphatase,and alanine and aspartate aminotransferases were measured.Cytokeratin 19(CK19)monoclonal antibody was used to enumerate CTCs,and CD133 and CD90 were used to enumerate CSCs by flow cytometry.The expression levels of the CSCs markers(CD133 and CD90)as well as telomerase,melanoma antigen encoding gene 1(MAGE1)and MAGE3 were assessed by RTPCR and quantitative real-time polymerase chain reactions.The number of CTCs and/or the expression levels of CK19,CD133,telomerase,MAGE1 and MAGE3 were correlated to the standard clinicopathologic prognostic factors and disease progression.RESULTS:Levels of AFP,alkaline phosphatase and aspartate aminotransferase were significantly different among the HCC,CH and control groups(P<0.001),whereas alanine aminotransferase differed significantly between patient(HCC and CH)and control groups(P<0.001).At the specified cutoff values determine by flow cytometry,CK19(49.8),CD90(400)and CD133(73)were significantly higher in the blood of HCC patients compared to those in the CH and control groups(P<0.001).On the other hand,CD133 at a 69.5 cutoff was significantly higher in the CH compared to the control group(P≤0.001).Telomerase,MAGE1 and MAGE3RNA were expressed in 55.71%,60.00%and 62.86%of the HCC patients,respectively,but were not detected in patients in the CH or control groups,which were statistically significant(Ps<0.001).The expression levels of telomerase,CD90,MAGE3,CD133 and CK19 were all significantly associated with high tumor grade and advanced stage in HCC patients(all P s<0.05).CONCLUSION:CTC counts and AFP,CK19,telomerase,and MAGE1/MAGE3 expression predict disease progression in patients with HCV,whereas telomerase,MAGE3,CD90,CD133 and CK19 are prognostic mark- | Abeer A Bahnassy Abdel-Rahman N Zekri Ahmed El-Bastawisy Amal Fawzy Marwa Shetta Nehal Hussein Dalia Omran Abdallah A S Ahmed Samir S El-Labbody | 2014 | World Journal of Gastroenterology2014，20，48： | 9 |
| 3 | Biochemical changes in phenols,flavonoids,tannins,vitamin E,β-carotene and antioxidant activity during soaking of three white sorghum varieties显示文摘Objective:To investigate the changes in total phenols,flavonoids,tannins,vitamin E, β-carotene and antioxidant activity during soaking of three white sorghum varieties.Methods: The changes in total phenols,total ilavonoids,tannins,phenolic acids compounds,flavonoid components,vitamin E,P-carotene and antioxidant activity during soaking of sorghum grains were determined.Results:Total phenols,total flavonoids,tannins,vitamin E,P-carotene and antioxidant activity in raw sorghum were ranged from 109.21 to 116.70,45.91 to 54.69,1.39 to 21.79 mg/100 g,1.74 to 5.25,0.54 to 1.19 mg/kg and 21.72%to 27.69%and 25.29%to 31.97%,respectively. The above measured compounds were significantly decreased after soaking.p-Hydroxybenzoic acid,vanillic acid,syringic acid and cinnamic acid represent the major phenolic acids in Dorado variety.While ferulic acid,p-coumaric acid,gallic acid and caffeic acid represent the major phenolic acids in Shandaweel-6.On the other hand,protocatechuic acid represents the major phenolic acids in Giza-15.Regarding flavonoids components,Dorado was the highest variety in kampferol and naringenin while Shandaweel-6 was the highest variety in luteolin, apigenin,hypersoid,quercelin and christen.Finally,Giza-15 was the highest variety in catechin. Phenolic acids,flavonoid compounds and antioxidant activities were decreased after soaking. Conclusions:Sorghum varieties have moderate quantities from total phenols,total flavonoids, tannins,phenolic acids compounds,flavonoid components,vitamin E,P-carotene and antioxidant activity which decreased after soaking. | Abd El-Moneim MR Afify Hossam S El-Beltagi Samiha M Abd El-Salam Azza A Omran | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，3： | 7 |
| 4 | Noninvasive assessment of hepatic fibrosis in Egyptian patients with chronic hepatitis C virus infection显示文摘AIM: To evaluate the accuracy of specific biochemical markers for the assessment of hepatic fibrosis in patients with chronic hepatitis C virus (HCV) infection. METHODS: One hundred and fifty-four patients with chronic HCV infection were included in this study; 124 patients were non-cirrhotic, and 30 were cirrhotic. The following measurements were obtained in all patients: serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, total bilirubin, prothrombin time and concentration, complete blood count, hepatitis B surface antigen (HBsAg), HCVAb, HCV-RNA by quantitative polymerase chain reaction, abdominal ultrasound and ultrasonic-guided liver biopsy. The following ratios, scores and indices were calculated and compared with the results of the histopathological examination: AST/ALT ratio (AAR), age platelet index (API), AST to platelet ratio index (APRI), cirrhosis discriminating score (CDS), Pohl score, G teborg University Cirrhosis Index (GUCI). RESULTS: AAR, APRI, API and GUCI demonstrated good diagnostic accuracy of liver cirrhosis (80.5%, 79.2%, 76.6% and 80.5%, respectively); P values were: < 0.01, < 0.05, < 0.001 and < 0.001, respectively. Among the studied parameters, AAR and GUCI gave the highest diagnostic accuracy (80.5%) with cutoff values of 1.2 and 1.5, respectively. APRI, API and GUCI were significantly correlated with the stage of fibrosis (P < 0.001) and the grade of activity (P < 0.001, < 0.001 and < 0.005, respectively), while CDS only correlated significantly with the stage of fibrosis (P < 0.001) and not with the degree of activity (P > 0.05). In addition, we found significant correlations for the AAR, APRI, API, GUCI and Pohl score between the non-cirrhotic (F0, F1, F2, F3) and cirrhotic (F4) groups (P values: < 0.001, < 0.05, < 0.001, < 0.001 and < 0.005, respectively; CDS did not demonstrate significant correlation (P > 0.05). CONCLUSION: The use of AAR, APRI, API, GUCI and Pohl score measurements may decrease the need for liver biopsies in diagnosing cirrhosis, especially in Egypt, where resources are limited. | Shawky Abdelhamid Fouad Serag Esmat Dalia Omran Laila Rashid Mohamed H Kobaisi | 2012 | World Journal of Gastroenterology2012，18，23： | 6 |
| 5 | Association between low molecular polypeptide 7 single nucleotide polymorphism and response to therapy in hepatitis C virus infection显示文摘AIM: To investigate the relationship between low molecular polypeptide-7 (LMP-7) gene polymorphism and response to interferon (IFN) therapy in chronic hepatitis C virus (HCV) patients. METHODS: LMP-7 polymorphism at codon 49 with nucleotide substitution from A to C was amplified in 104 chronic HCV patients of genotype 4. The amplicons were digested with restriction endonuclease Bsm I and the produced restriction fragment length polymorphism was analyzed. Patients received IFN + regional blood volume therapy for 48 wk and the frequency of thissingle nucleotide polymorphism (SNP) was statistically correlated with treatment response. The exclusion criteria for these patients were stated by the national health program for treating viral hepatitis. Main exclusion criteria included co-infection with hepatitis B virus or schistosomiasis, thyroid dysfunction, uncontrolled diabetes mellitus, history of long term drug or alcohol intake and autoimmune hepatitis. Multivariate analyses were done to correlate LMP-7 SNP plus several factors such as age, gender, weight, serum alpha-fetoprotein (AFP) and alanine aminotransferase levels, liver activity, fibrosis score and viral load with response to therapy. RESULTS: The data presented in this study clearly demonstrated statistically significant differences between sustained virological response (SVR) (defined as the absence of HCV RNA levels in the patient's sera at least 6 mo after discontinuation of treatment) and non-response (NR) (where HCV RNA levels in the patient's sera never become undetectable for 6 mo during or after treatment). Variables were described as odds ratio with 95%CI. The data were considered significant if P values were ≤ 0.05; highly significant if P < 0.01 and very highly significant if P < 0.001. Current data showed that 91.7% of patients carrying LMP-7 C/C allele were associated with SVR, while the other two genotypes C/A and A/A were associated with NR patients, 83.3% and 64.3% respectively, showing that genotype CC was strongly associated with response to interferon (95%CI: 12.0719-134.6572, P = 0.0001). The majority of parameters recorded in SVR and NR patients included higher values of mean age (P = 0.004), alanine aminotransferase (P = 0.001), AFP (P = 0.001), body weight (P = 0.025), viral load (P = 0.025), higher fibrosis and histological activity index indices among NR vs SVR patients. Also, the multivariate statistical analysis of the different factors of fibro-sis score, liver activity grade, genotypes and alleles of LMP-7 gene polymorphism in responders and NRs of HCV patients in this study showed that HCV patients with A allele had a very highly significant association with the NRs, high fibrosis and higher liver activity, while the C allele had a very highly significant association with the responders, low fibrosis and lower liver activity (95%CI: 3.5800-13.2519, P = 0.0001).CONCLUSION: LMP-7 SNP is a candidate gene that should be considered when designing a mathematical model for predicting response to therapy and disease progression in HCV patients. | Moataza H Omran Basma E Fotouh Samar S Youssef Noha E Ibrahim Wael Nabil EL-Sayed M Mahdy Wafaa G Shosha Mostafa K El-Awady | 2013 | World Journal of Hepatology2013，5，3： | 4 |
| 6 | Ion-transport characteristics of new-old concrete composite system显示文摘New-old concrete composite system usually exists in concrete repairing structure.In the present work,series of experiments were carried out to investigate permeability and ion diffusion properties of new-old concrete composite by measuring 6-hour coulomb charge and chloride diffusivity.The interrelation among transport properties of new-old composites,new,and old concretes was also discussed.Results indicate that the permeability and chloride diffusivity of new-old concrete composite system closely interrelate to the corresponding new concrete and old concrete.The interfacial transition zone between new concrete and old concrete greatly influences the transport property of new-old concrete system.Compared with the corresponding new concrete and old concrete lower permeability and diffusivity values for the new-old concrete composites can be achieved by choosing suitable new concrete.It is possible to design the tailor-made new-old concrete composite system for repair given the transport property. | 龙广成 谢友均 丁巍巍 Ahmed OMRAN | 2014 | Journal of Central South University2014，21，2： | 4 |
| 7 | Flow cytometric detection of hepatitis C virus antigens in infected peripheral blood leukocytes: Binding and entry显示文摘AIM: We designed two synthetic-core-specific peptides core 1 (C1) and core 2 (C2), and an E1-specific peptide (E1). We produced specific polyclonal antibodies againstthese peptides and used the antibodies for detection of HCV antigens on surface and within infected peripheral blood leukocytes.METHODS: Peripheral blood from a healthy individual who tested negative for HCV RNA was incubated with HCV type 4 infected serum for 1 h and 24 h at 37 ℃. Cells were stained by direct and indirect immunofluorescence and measured by flow cytometry.RESULTS: After 1 h of incubation, antibodies against C1,C2, and E1 detected HCV antigens on the surface of 27%,26% and 73% of monocytes respectively, while 10%, 5% and 9% of lymphocytes were positive with anti-C1, anti-C2 and anti-E1 respectively. Only 1-3% of granulocytes showed positive staining with anti-C1, anti-C2 and anti E1 antibodies. After 24 h of incubation, we found no surface staining with anti-C1, anti-C2 or anti-E1. Direct immunostaining using anti-C2 could not detect intracellular HCV antigens, after 1 h of incubation with the virus, while after 24 h of incubation, 28% of infected cells showed positive staining. Only plus strand RNA was detectable intracellularly as early as 1 h after incubation, and remained detectable throughout 48 h post-infection.Interestingly, minus RNA strand could not be detected after 1 h, but became strongly detectable intracellularly after 24 h post-infection.CONCLUSION: Monocytes and lymphocytes are the preferred target cells for HCV infection in peripheral blood leukocytes. Our specific anti-core and anti-E1 antibodies are valuable reagents for demonstration of HCV cell cycle.Also, HCV is capable of infecting and replicating in peripheral blood mononuclear cells as confirmed by detection of minus strand HCV RNA as well as intracellular staining of core HCV antigen. | Mostafa K El-Awady Ashraf A Tabll El-Rashdy M Redwan Samar Youssef Moataza H Omran Fouad Thakeb Maha El-Demellawy | 2005 | World Journal of Gastroenterology2005，11，33： | 4 |
| 8 | A longitudinal study of SARS-CoV-2-infected patients reveals a high correlation between neutralizing antibodies and COVID-19 severity显示文摘Understanding the immune responses elicited by SARS-CoV-2 infection is critical in terms of protection against reinfection and,thus,for public health policy and vaccine development for COVID-19.In this study,using either live SARS-CoV-2 particles or retroviruses pseudotyped with the SARS-CoV-2 S viral surface protein(Spike),we studied the neutralizing antibody(nAb)response in serum samples from a cohort of 140 SARS-CoV-2 qPCR-confirmed infections,including patients with mild symptoms and also more severe forms,including those that required intensive care.We show that nAb titers correlated strongly with disease severity and with anti-spike IgG levels.Indeed,patients from intensive care units exhibited high nAb titers;conversely,patients with milder disease symptoms had heterogeneous nAb titers,and asymptomatic or exclusive outpatient-care patients had no or low nAbs.We found that nAb activity in SARS-CoV-2-infected patients displayed a relatively rapid decline after recovery compared to individuals infected with other coronaviruses.Moreover,we found an absence of cross-neutralization between endemic coronaviruses and SARS-CoV-2,indicating that previous infection by human coronaviruses may not generate protective nAbs against SARS-CoV-2.Finally,we found that the D614G mutation in the spike protein,which has recently been identified as the current major variant in Europe,does not allow neutralization escape.Altogether,our results contribute to our understanding of the immune correlates of SARS-CoV-2-induced disease,and rapid evaluation of the role of the humoral response in the pathogenesis of SARS-CoV-2 is warranted. | Vincent Legros Solène Denolly Manon Vogrig Bertrand Boson Eglantine Siret Josselin Rigaill Sylvie Pillet Florence Grattard Sylvie Gonzalo Paul Verhoeven Omran Allatif Philippe Berthelot Carole Pélissier Guillaume Thiery Elisabeth Botelho-Nevers Guillaume Millet Jérôme Morel Stéphane Paul Thierry Walzer François-Loïc Cosset Thomas Bourlet Bruno Pozzetto | 2021 | Cellular & Molecular Immunology2021，18，2： | 3 |
| 9 | Predictors of hypoglycemia in insulin-treated patients with type 2 diabetes mellitus in Basrah显示文摘AIM To measure the incidence and determinants(predictors) of hypoglycemia among patients with type 2 diabetes mellitus(T2DM) who were on insulin treatment for at least one year. METHODS The present study is an out-patients based inquiry about the risk and predictors of hypoglycemia among patients with T2DM seeking care at the Al-Faiha Specialized Diabetes, Endocrine, and Metabolism Center, in Basrah over a period of 7 mo(from 15^(th) of April, 2013 to 15^(th) of October, 2013). The data used in the study were based on all detailed interview and selected laboratory investigations. A total of 336 patients could be included in the study.RESULTS The incidence of overall hypoglycemia among the studied patients was 75.3% within the last 3 mo preceding the interview. The incidence of hypoglycemia subtypes were 10.2% for severe hypoglycemia requiring medical assistance in the hospital, 44.36% for severe hypoglycemia treated at home by family; this includes both confirmed severe hypoglycemia with an incidence rate of 14.6% and unconfirmed severe hypoglycemia for which incidence rate was 29.76%. Regarding mild self-treated hypoglycemia, the incidence of confirmed mild hypoglycemia was 21.42%, for unconfirmed mildhypoglycemia the incidence rate was 50.0% and for total mild hypoglycemia, the incidence rate was 71.42%. The most important predictors of hypoglycemia were a peripheral residence, increasing knowledge of hypoglycemia symptoms, in availability and increasing frequency of self-monitoring blood glucose, the presence of peripheral neuropathy, higher diastolic blood pressure, and lower Hemoglobin A1c.CONCLUSION Hypoglycemia is very common among insulin-treated patients with T2DM in Basrah. It was possible to identify some important predictors of hypoglycemia. | Dhuha Tarik Nassar Omran S Habib Abbas Ali Mansour | 2016 | World Journal of Diabetes2016，7，18： | 3 |

| 17 | Towards hepatitis C virus elimination:Egyptian experience,achievements and limitations显示文摘Worldwide, more than one million people die each year from hepatitis C virus(HCV) related diseases, and over 300 million people are chronically infected with hepatitis B or C. Egypt used to be on the top of the countries with heavy HCV burden. Some countries are making advances in elimination of HCV, yet multiple factors preventing progress; remain for the majority. These factors include lack of global funding sources for treatment, late diagnosis, poor data, and inadequate screening. Treatment of HCV in Egypt has become one of the top national priorities since 2007. Egypt started a national treatment program intending to provide cure for Egyptian HCV-infected patients. Mass HCV treatment program had started using Pegylated interferon and ribavirin between 2007 and 2014. Yet, with the development of highly-effective direct acting antivirals(DAAs) for HCV, elimination of viral hepatitis has become a real possibility. The Egyptian National Committee for the Control of Viral Hepatitis did its best to provide Egyptian HCV patients with DAAs. Egypt adopted a strategy that represents a model of care that could help other countries with high HCV prevalence rate in their battle against HCV. This review covers the effects of HCV management in Egyptian real life settings and the outcome of different treatment protocols. Also, it deals with the current and future strategies for HCV prevention and screening as well as the challenges facing HCV elimination and the prospect of future eradication of HCV. | Dalia Omran Mohamed Alboraie Rania A Zayed Mohamed-Naguib Wifi Mervat Naguib Mohamed Eltabbakh Mohamed Abdellah Ahmed Fouad Sherief Sahar Maklad Heba Hamdy Eldemellawy Omar Khalid Saad Doaa Mohamed Khamiss Mohamed El Kassas | 2018 | World Journal of Gastroenterology2018，24，38： | 2 |
