| 1 | An efficient enhanced k-means clustering algorithm显示文摘In k-means clustering, we are given a set of n data points in d-dimensional space úd and an integer k and the problem is to determine a set of k points in úd, called centers, so as to minimize the mean squared distance from each data point to its nearest center. In this paper, we present a simple and efficient clustering algorithm based on the k-means algorithm, which we call en- hanced k-means algorithm. This algorithm is easy to implement, requiring a simple data structure to keep some information in each iteration to be used in the next iteration. Our experimental results demonstrated that our scheme can improve the computational speed of the k-means algorithm by the magnitude in the total number of distance calculations and the overall time of computation. | FAHIM A.M SALEM A.M TORKEY F.A RAMADAN M.A | 2006 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2006，7，10： | 28 |

| 3 | Rubber band ligation for 750 cases of symptomatic hemorrhoids out of 2200 cases显示文摘AIM: To study the results for the treatment of symptomatic hemorrhoids using rubber band ligation (RBL) method. METHODS: A retrospective study for 750 patients who came to the colorectal unit from June, 1998 to September, 2006, data was retrieved from archived fi les. RBL was performed using the Mc Gown applicator on an outpatient basis. The patients were asked to return to out-patient clinic for follow up at 2 wk, 1 mo, 6 mo and through telephone call every 6 mo for 2 years). RESULTS: After RBL, 696 patients (92.8%) were cured with no difference in outcome for second or third degree hemorrhoids (P = 0.31). Symptomatic recurrence was detected in 11.04% after 2 years. A total of 52 patients (6.93%) had 77 complications from RBL which required no hospitalization. Complications were pain, rectal bleeding and vaso-vagal symptoms(4.13%, 4.13% and 1.33% of patients, respectively). At 1 mo there were a significant improvement in mean SF-36 scores over baseline in five items, while after 2 years there were improvement in all items over baseline, but not significant. No significant manometeric changes after band ligation. CONCLUSION: RBL is a simple, safe and effective method for treating symptomatic second and third degree hemorrhoids as an out patient procedure with signifi cant improvement in quality of life. RBL doesn't alter ano-rectal functions. | Ayman M El Nakeeb Amir A Fikry Waleed H Omar Elyamani M Fouda Tito A El Metwally Hosam E Ghazy Sabry A Badr Mohmed Y Abu Elkhar Salih M Elawady Hisham H Abd Elmoniam Waiel W Khafagy Mosaad M Morshed Ramadan E El Lithy Mohamed E Farid | 2008 | World Journal of Gastroenterology2008，14，42： | 24 |
| 4 | Premature ejaculation:an update on definition and pathophysiology显示文摘Premature ejaculation(PE)is the most comm on male sexual dysfunction,which represents a diag no stic as well as a therapeutic challenge for physicians.However,no universally accepted definition is currently available for PE.As a result,physicians continue to diagnose patients with PE according to major guidelines set by the professional societies.These guidelines either recommend the use of validated questionnaires or patient-reported outcomes.Recent efforts directed toward classifying PE may help provide a better understanding of the prevalence and risk factors of this disorder.While the exact etiology of PE has not been clearly elucidated,several risk factors have been strongly reported in the literature.Clearly,to understand the revised definition of PE,its etiology and pathophysiology is necessary to improve the clinical management of this medical condition and form the basis of future research in this regard.In this review,we highlight the past and current definitions of PE and present an appraisal on the classifications and theories suggested for the etiopathogenesis of PE. | Mohammed Abu El-Hamd Ramadan Saleh Ahmad Majzoub | 2019 | Asian Journal of Andrology2019，21，5： | 12 |
| 5 | Age distribution,polyps and rectal cancer in the Egyptian population-based cancer registry显示文摘AIM:To describe the clinical and epidemiologic profiles of the disease and to compare the findings with those generated from the previous hospital-based studies.METHODS:The Gharbiah cancer registry is the only population-based cancer registry in Egypt since 1998.We analyzed the data of all colorectal cancer patients included in the registry for the period of 1999-2007.All medical records of the 1364 patients diagnosed in Gharbiah during the study period were retrieved and the following information abstracted:age,residence,diagnosis date,grade,stage,topology,clinical characteristics,and histology variables.Egyptian census data for 1996 and 2006 were used to provide the general population's statistics on age,sex,residence and other related demographic factors.In addition to age-and sex-specific incidence rate analyses,we analyze the data to explore the incidence distribution by rural-urban differences among the 8 districts of the province.We also compared the incidence rates of Gharbiah to the rates of the Surveillance Epidemiology and End Results(SEER) data of the United States.RESULTS:Over the 9 year-period,1364 colorectal cancer cases were included.The disease incidence under age 40 years was relatively high(1.3/10 5) while the incidence in the age groups 40 and over was very low(12.0/10 5,19.4/10 5 and 21.2/10 5 in the age groups 40-59 years,60-69 years and > 70 years,respectively).The vast majority of tumors(97.2%) had no polyps and 37.2% of the patients presented with primary lesions in the rectum.Colorectal cancer was more common in patients from urban(55%) than rural(45%) areas.Regional differences in colon and rectal cancer incidence in the 8 districts of the study province may reflect different etiologic patterns in this population.The registry data of Egypt shows a slightly higher incidence of colorectal cancer than the United States in subjects under age 40 years.The results also shows significantly lower incidence of colorectal cancer in subjects over age 40 years compared to the same age group in the United States SEER.CONCLUSION:Low rate of polyps,low incidence in older subjects,and high rate of rectal cancer in Egypt.Future studies should explore clinical and molecular disease patterns. | Darlene Veruttipong Amr S Soliman Samuel F Gilbert Taylor S Blachley Ahmed Hablas Mohamed Ramadan Laura S Rozek Ibrahim A Seifeldin | 2012 | World Journal of Gastroenterology2012，18，30： | 12 |

| 8 | Impact of the source and serial passaging of goat mesenchymal stem cells on osteogenic differentiation potential:implications for bone tissue engineering显示文摘Background: Adult mesenchymal stem cells(MSCs) can be conveniently sampled from bone marrow, peripheral blood, muscle, adipose and connective tissue, harvested from various species, including, rodents, dogs, cats, horses,sheep, goats and human beings. The MSCs isolated from adult tissues vary in their morphological and functional properties. These variations are further complicated when cells are expanded by passaging in culture. These differences and changes in MSCs must be considered prior to their application in the clinic or in a basic research study. Goats are commonly used as animal models for bone tissue engineering to test the potential of stem cells for bone regeneration. As a result, goat MSCs isolated from bone marrow or adipose tissue should be evaluated using in vitro assays, prior to their application in a tissue engineering project.Results: In this study, we compared the stem cell properties of MSCs isolated from goat bone marrow and adipose tissue. We used quantitative and qualitative assays with a focus on osteogenesis, including, colony forming unit, rate of cell proliferation, tri-lineage differentiation and expression profiling of key signal transduction proteins to compare MSCs from low and high passages. Primary cultures generated from each source displayed the stem cell characteristics,with variations in their osteogenic potentials. Most importantly, low passaged bone marrow MSCs displayed a significantly higher and superior osteogenic potential, and hence, will be the preferred choice for bone tissue engineering in future in vivo experiments. In the bone marrow MSCs, this process is potentially mediated by the p38 MAPK pathway. On the other hand, osteogenic differentiation in the adipose tissue MSCs may involve the p44/42 MAPK pathway.Conclusions: Based on these data, we can conclude that bone marrow and fat-derived MSCs undergo osteogenesis via two distinct signaling pathways. Even though the bone marrow MSCs are the preferred source for bone tissue engineering, the adipose tissue MSCs are an attractive alternative source and undergo osteo-differentiation differently from the bone marrow MSCs and hence, might require a cell-based enhancer/inducer to improve their osteogenic regenerative capacity. | Hoda Elkhenany Lisa Amelse Marc Caldwell Ramadan Abdelwahed Madhu Dhar | 2016 | Journal of Animal Science and Biotechnology2016，7，4： | 4 |
| 9 | Solid phase microextraction chemical biopsy tool for monitoring of doxorubicin residue during in vivo lung chemo-perfusion显示文摘Development of a novel in vivo lung perfusion(IVLP)procedure allows localized delivery of high-dose doxorubicin(DOX)for targeting residual micrometastatic disease in the lungs.However,DOX delivery via IVLP requires careful monitoring of drug level to ensure tissue concentrations of this agent remain in the therapeutic window.A small dimension nitinol wire coated with a sorbent of biocompatible morphology(Bio-SPME)has been clinically evaluated for in vivo lung tissue extraction and determination of DOX and its key metabolites.The in vivo Bio-SPME-IVLP experiments were performed on pig model over various(150 and 225 mg/m^(2))drug doses,and during human clinical trial.Two patients with metastatic osteosarcoma were treated with a single 5 and 7 μg/mL(respectively)dose of DOX during a 3-h IVLP.In both pig and human cases,DOX tissue levels presented similar trends during IVLP.Human lung tissue concentrations of drug ranged between 15 and 293 μg/g over the course of the IVLP procedure.In addition to DOX levels,Bio-SPME followed by liquid chromatography-mass spectrometry analysis generated 64 metabolic features during endogenous metabolite screening,providing information about lung status during drug administration.Real-time monitoring of DOX levels in the lungs can be performed effectively throughout the IVLP procedure by in vivo Bio-SPME chemical biopsy approach.Bio-SPME also extracted various endogenous molecules,thus providing a real-time snapshot of the physiology of the cells,which might assist in the tailoring of personalized treatment strategy. | Barbara Bojko Nikita Looby Mariola Olkowicz Anna Roszkowska Bogumiła Kupcewicz Pedro Reck dos Santos Khaled Ramadan Shaf Keshavjee Thomas K.Waddell German Goomez-Rios Marcos Tascon Krzysztof Gorynski Marcelo Cypel Janusz Pawliszyn | 2021 | Journal of Pharmaceutical Analysis2021，11，1： | 3 |

| 12 | Structural and Tectonic Evolution of El-Faiyum Depression,North Western Desert,Egypt Based on Analysis of Landsat ETM+,and SRTM Data显示文摘False color Landsat ETM+ (bands 7, 4, 2 in RGB) and SRTM images of the El-Faiyum depression, Egypt, highlights major NE-SW faults and other lineaments trending NW-SE and N-S. Airborne magnetic data reveal some E-W subsurface faults which are not recognized on Landsat ETM+ and SRTM images. Ratio images (5/7, 3/1, 4/3) and (5/7, 5/1, 4) were used for lithological discrimination of different rock types. The El-Faiyum area is occupied by sedimentary rocks of Middle Eocene, Upper Eocene, Oligocene, Lower Miocene, Pliocene, Pleistocene and Holocene. Understanding the structural regime of El-Faiyum depression in the Western Desert of Egypt is significant in relation to the neotectonics of the Nile Delta and to the development of new communities west of the delta. The area is covered by Late Cretaceous, Middle to Late Eocene deposits, Oligocene deposits (comprising fluviatile sediments and basalt sheets) and Pliocene and Quaternary alluvium and sand deposits. New geological and structural maps were prepared at a scale of 1 : 100 000 using Landsat ETM+ and SRTM images coupled with extensive field work. The major structural trends are E-W, ENE, NS and NW-the same trends observed elsewhere in North Africa from NW Sudan to NE Egypt including north and central Sinai. El-Faiyum depression is a structurally-controlled tectonic basin, marked by northeast-striking faults along its northern margin. These faults are parallel to similar faults of the Syrian arc fold belt, which includes a group of related faults, folds, push-up structures, and basins. Qarun Lake is located in the northern part of El-Faiyum depression, at a right-step between two strands of the NE striking fault system. We have suggested elsewhere that El-Faiyum depression is a pull-apart basin related to extension between these mismatched strands of strike-slip faults. The E-W structures are probably related to the relative motion between south Europe and north Egypt and closure of the Neotethys. The continuation of these faults in the present area is only detected from magnetic and seismic studies. The question that needs to be raised is why these old structural features have been reactivated in recent times. Thus, the presence of these fault zones must be heeded in all development plans for El-Faiyum region. | Timothy M Kusky Talaat M Ramadan Mahmoud M Hassaan Safwat Gabr | 2011 | Journal of Earth Science2011，22，1： | 3 |

| 18 | Plasma D-dimer level in early and late-onset neonatal sepsis显示文摘BACKGROUND Neonatal sepsis is a life-threatening disease.Early diagnosis is essential,but no single marker of infection has been identified.Sepsis activates a coagulation cascade with simultaneous production of the D-dimers due to lysis of fibrin.Ddimer test reflects the activation of the coagulation system.AIM To assess the D-dimer plasma level,elaborating its clinicopathological value in neonates with early-onset and late-onset neonatal sepsis.METHODS The study was a prospective cross-sectional study that included ninety neonates;divided into three groups:Group I:Early-onset sepsis(EOS);Group II:Late-onset sepsis(LOS);and GroupⅢ:Control group.We diagnosed neonatal sepsis according to our protocol.C-reactive protein(CRP)and D-dimer assays were compared between EOS and LOS and correlated to the causative microbiological agents.RESULTS D-dimer was significantly higher in septic groups with a considerably higher number of cases with positive D-dimer.Neonates with LOS had substantially higher levels of D-dimer than EOS,with no significant differences in CRP.Neonates with LOS had a significantly longer hospitalization duration and higher gram-negative bacteriemia and mortality rates than EOS(P<0.01).Gramnegative bacteria have the highest D-dimer levels(Acinetobacter,Klebsiella,and Pseudomonas)and CRP(Serratia,Klebsiella,and Pseudomonas);while gram-positive sepsis was associated with relatively lower levels.D-dimer had a significant negative correlation with hemoglobin level and platelet count;and a significant positive correlation with CRP,hospitalization duration,and mortality rates.The best-suggested cut-off point for D-dimer in neonatal sepsis was 0.75 mg/L,giving a sensitivity of 72.7%and specificity of 86.7%.The D-dimer assay has specificity and sensitivity comparable to CRP in the current study.CONCLUSION The current study revealed a significant diagnostic value for D-dimer in neonatal sepsis.D-dimer can be used as an adjunct to other sepsis markers to increase the sensitivity and specificity of diagnosing neonatal sepsis. | Mohammed Al-Biltagi Ehab M Hantash Mohammed Ramadan El-Shanshory Enayat Aly Badr Mohamed Zahra Manar Hany Anwar | 2022 | World Journal of Critical Care Medicine2022，11，3： | 2 |
| 19 | Expression levels of pro-inflammatory interleukin-8 and certain antimicrobial peptides in concurrent with bacterial conjunctivitis显示文摘AIM:To detect the quantitative expression levels of the pro-inflammatory interleukin-8(IL8),antimicrobial peptides human beta defense-2(HBD2),and human beta defense-3(HBD3)genes in bacterial conjunctivitis.METHODS:The human conjunctival epithelial cells were obtained using the impression cytology technique from healthy controls and patients.The genes expression levels were determined utilizing a reverse transcription quantitative polymerase chain reaction(RT-q PCR).The contribution of causative agent type,the number of isolates and severity of clinical features,in the increase of genes expression was also determined.RESULTS:The RT-q PCR showed that IL8,HBD2,and HBD3 expression increased in bacterial conjunctivitis as compared to healthy control(P<0.001).In gram-negative bacterial conjunctivitis,HBD2 was highly up-regulated(P<0.001)compared to other types of bacterial conjunctivitis.In mixed bacterial conjunctivitis,a direct correlation between HBD2 up-regulation and HBD3 up-regulation was observed(P<0.05).The severity of clinical features was related to the up-regulation of IL8 and HBD2(P<0.05).CONCLUSION:IL8,HBD2,and HBD3 are immuneeffectors in infectious conjunctivitis.HBD2 is active during different bacterial conjunctivitis but is more released with gram-negative bacteria compared to gram-positive bacteria.HBD3 is an obvious defender in different bacterial conjunctivitis. | Alaa El-Dien Shawky Hosny Zeinab El-Demerdash El-Bazza Mohammed Abdelhalim Ramadan Maha Ahmed Shafik Mahmoud Ahmed Shafeek Rania Abdelmonem Khattab | 2021 | International Journal of Ophthalmology(English edition)2021，14，5： | 2 |
