| 1 | Effect of alternative antibiotics in treatment of cefotaxime resistant spontaneous bacterial peritonitis显示文摘AIM:To evaluate effective alternative antibiotics in treatment of cefotaxime-resistant spontaneous bacterial peritonitis.METHODS:One hundred cirrhotic patients with spontaneous bacterial peritonitis [ascitic fluid polymorphonuclear cell count(PMNLs) ≥ 250 cells/mm 3 at admission] were empirically treated with cefotaxime sodium 2 g/12 h and volume expansion by intravenous human albumin.All patients were subjected to history taking,complete examination,laboratory tests(including a complete blood cell count,prothrombin time,biochemical tests of liver and kidney function,and fresh urine sediment),chest X-ray,a diagnostic abdominal paracentesis,and the sample subjected to total and differential cell count,chemical examination,aerobic and anaerobic cultures.Patients were divided after 2 d by a second ascitic PMNL count into group Ⅰ;patients sensitive to cefotaxime(n = 81),group Ⅱ(n = 19);cases resistant to cefotaxime(less than 25% decrease in ascitic PMNL count).Patients of group Ⅱ were randomly assigned into meropenem(n = 11) or levofloxacin(n = 8) subgroups.All patients performed an end of treatment ascitic PMNL count.Patients were considered improved when:PMNLs decreased to < 250 cells/mm 3,no growth in previously positive culture cases,and improved clinical manifestations with at least 5 d of antibiotic therapy.RESULTS:Age,sex,and Child classes showed no significant difference between group Ⅰ and group Ⅱ.Fever and abdominal pain were the most frequent manifestations and were reported in 82.7% and 80.2% of patients in group Ⅰ and in 94.7% and 84.2% of patients in group Ⅱ,respectively.Patients in group Ⅱ had a more severe ascitic inflammatory response than group Ⅰ and this was demonstrated by more ascitic lactate dehydrogenase(LDH) [median:540 IU/L(range:150-1200 IU/L) vs median:240 IU/L(range:180-500 IU/L),P = 0.000] and PMNL [median:15 000 cell/mm 3(range:957-23 822 cell/mm 3) vs 3400 cell/mm 3(range:695-26 400 cell/mm 3),P = 0.000] counts.Ascitic fluid culture was positive in 32% of cases.Cefotaxime failed in 19% of patients;of these patients,11(100%) responded to meropenem and 6(75%) responded to levofloxacin.Two patients with failed levofloxacin therapy were treated according to the in vitro culture and sensitivity(one case was treated with vancomycin and one case was treated with ampicillin/sulbactam).In group Ⅱ the meropenem subgroup had higher LDH(range:108-860 IU/L vs 120-491 IU/L,P = 0.042) and PMNL counts(range:957-23 822 cell/mm 3 vs 957-15 222 cell/mm 3,P = 0.000) at initiation of the alternative antibiotic therapy;there was no significant difference in the studied parameters between patients responsive to meropenem and patients responsive to levofloxacin at the end of therapy(mean ± SD:316.01 ± 104.03PMNLs/mm 3 vs 265.63 ± 69.61 PMNLs/mm 3,P = 0.307).The isolated organisms found in group Ⅱ were;enterococci,acinetobacter,expanded-spectrum β-lactamase producing Escherichia coli,β-lactamase producing Enterobacter and Staphylococcus aureus.CONCLUSION:Empirical treatment with cefotaxime is effective in 81% of cases;meropenem is effective in cefotaxime-resistant cases. | Ahmed Abouelkhair Badawy Tarik Ibrahim Zaher Samar Mahmoud Sharaf Mohamed Hassan Emara Noha Elsaid Shaheen Talaat Fathy Aly | 2013 | World Journal of Gastroenterology2013，19，8： | 13 |
| 2 | Comparison of perceived pain and patients’ satisfaction with traditional local anesthesia and single tooth anesthesia: A randomized clinical trial显示文摘BACKGROUND Contemporary innovations in the area of local anesthesia have attempted to provide an absolutely pain free experience for patients.Since the introduction of Computer-Controlled Local Anesthetic Delivery Systems to dentistry,many studies have compared its efficacy and safety to conventional anesthesia.However,very few studies have compared single tooth anesthesia(STA)and traditional local anesthesia.AIM To compare pain rating,changes in blood pressure,and heart rate during the local anesthetic injection.The secondary objectives were to measure the patients’level of satisfaction and the differences in anesthetic efficiency between the STA system and traditional local infiltration.METHODS A randomized controlled trial was conducted and a total of 80 patients with dental restorative needs were enrolled for the study.The patients were evaluated for their general physical status and oral clinical findings before enrollment.Information regarding perceived pain,changes in heart rate and blood pressure,and patients’satisfaction was collected using an electronic data form and was analyzed using paired and unpaired t-tests.RESULTS No significant difference was noted in perceived pain(P=0.59)and systolic blood pressure(P=0.09)during anesthetic injection using both traditional and STA techniques.STA patients had a significantly higher heart rate during anesthesia,although a statistically significant difference was noted among the traditional anesthesia and the STA groups even before anesthesia.During the restorative procedure,less pain was perceived by STA patients on the Wong-Baker FACES pain scale,which was statistically significant(P<0.001).Analyses of post-procedure patient responses showed that STA patients had a significantly better treatment experience and preferred to have the same method of injection in the future(P=0.04).CONCLUSION STA system can provide less painful and more comfortable restorative treatment procedures in comparison to the traditional infiltration technique. | Mohammad I Al-Obaida Mehdiya Haider Rawan Hashim Wafa AlGheriri Sree Lalita Celur Samar A Al-Saleh Ebtissam M Al-Madi | 2019 | World Journal of Clinical Cases2019，7，19： | 8 |

| 4 | Molecular signaling mechanisms of apoptosis in hereditary non-polyposis colorectal cancer显示文摘Colorectal cancer is the second most leading cause of cancer related deaths in the western countries. One of the forms of colorectal cancer is hereditary non-polyposis colorectal cancer (HNPCC), also known as 'Lynch syndrome'. It is the most common hereditary form of cancer accounting for 5%-10% of all colon cancers. HNPCC is a dominant autosomal genetic disorder caused by germ line mutations in mismatch repair genes. Human mismatch repair genes play a crucial role in genetic stability of DNA, the inactivation of which results in an increased rate of mutation and often a loss of mismatch repair function. Recent studies have shown that certain mismatch repair genes are involved in the regulation of key cellular processes including apoptosis. Thus, differential expression of mismatch repair genes particularly the contributions of MLH1 and MSH2 play important roles in therapeutic resistance to certain cytotoxic drugs such as cisplatin that is used normally as chemoprevention. An understanding of the role of mismatch repair genes in molecular signaling mechanism of apoptosis and its involvement in HNPCC needs attention for further work into this important area of cancer research, and this review article is intended to accomplish that goal of linkage of apoptosis with HNPCC. The current review was not intended to provide a comprehensive enumeration of the entire body of literature in the area of HNPCC or mismatch repair system or apoptosis; it is rather intended to focus primarily on the current state of knowledge of the role of mismatch repair proteins in molecular signaling mechanism of apoptosis as it relates to understanding of HNPCC. | Samar Hassen Nawab Ali Parimal Chowdhury | 2012 | World Journal of Gastrointestinal Pathophysiology2012，3，3： | 7 |
| 5 | Efficient elimination of environmental pollutants through sorption-reduction and photocatalytic degradation using nanomaterials显示文摘With the rapid development of industrial,large amounts of different inorganic and organic pollutants are released into the natural environments.The efficient elimination of environmental pollutants,i.e.,photocatalytic degradation of persistent organic pollutants into nontoxic organic/inorganic chemicals,in-situ solidification or sorption-reduction of heavy metal ions,is crucial to protect the environment.Nanomaterials with large surface area,active sites and abundant functional groups could form strong surface complexes with different kinds of pollutants and thereby could efficiently eliminate the pollutants from the aqueous solutions.In this review,wemainly focused on the recent works about the synthesis of nanomaterials and their applications in the efficient elimination of different organic and inorganic pollutants from wastewater and discussed the interaction mechanism from batch experimental results,the advanced spectroscopy techniques and theoretical calculations.The adsorption and the photocatalytic reduction of organic pollutants and the sorption/reduction of heavy metal ions are generally considered as the mainmethods to decrease the concentration of pollutants in the natural environment.This review highlights anew way for the real applications of novel nanomaterials in environmental pollution management,especially for the undergraduate students to understand the recent works in the elimination of different kinds of inorganic and organic chemicals in the natural environmental pollution management. | Njud SAlharbi Baowei Hu Tasawar Hayat Samar Omar Rabah Ahmed Alsaedi Li Zhuang Xiangke Wang | 2020 | Frontiers of Chemical Science and Engineering2020，14，6： | 5 |
| 6 | Phytochemical studies and anti-ulcerative colitis effect of Moringa oleifera seeds and Egyptian propolis methanol extracts in a rat model显示文摘Objective: To analyze the phytochemical constituents, and to explore potential protective effect of the methanol extract of Moringa oleifera(M. oleifera) seeds and Egyptian propolis, each alone or concurrently administered on acetic acid-induced ulcerative colitis in rats. Methods: Eight groups of 5 rats each were used: normal control group with distilled water, model group, two groups with M. oleifera seeds(100 and 200 mg/kg), two groups with propolis(50 and 100 mg/kg), one group with concurrent administration of both, and one group with prednisolone(reference drug). Macro-and microscopic picture, ulcer index and lesion scores, oxidative markers, inflammatory mediators, in vitro activity of the inflammatory enzymes and 1, 1-diphenyl-2-picrylhydrazyl free radicals scavenging activity were evaluated. The phytochemical constituents of both extracts were explored by GC-MS analysis. Results: Both treatments modulated the macro-and microscopic picture, decreased the ulcerative index, lesion score, oxidative markers and inflammatory mediators, and inhibited the COX-1 and COX-2 enzymes. Propolis appeared to be powerful free radicals scavenger. A powerful synergistic effect of both treatments in modulating the course of the disease was reported. GCMS analysis of methanol extract of M. oleifera seeds and propolis revealed the presence of 50 and 34 compounds, respectively. Conclusions: M. oleifera seeds and propolis methanol extracts have modulated the course of acetic acid-induced ulcerative colitis. Moreover, both treatments induce a good synergistic effect against the disease. Isolation of the active constituents is recommended. | Attia H.Atta Samar M.Mouneir Soad M.Nasr Doaa Sedky Amany M.Mohamed Shimaa A.Atta Hassan Mohamed Desouky | 2019 | Asian Pacific Journal of Tropical Biomedicine2019，9，3： | 4 |
| 7 | 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 |

| 9 | 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 |
| 10 | Effect of periocular injection of celecoxib and propranolol on ocular level of vascular endothelial growth factor in a diabetic mouse model显示文摘AIM: To investigate the effects of periocular injection of propranolol and celecoxib on ocular levels of vascular endothelial growth factor(VEGF) in a diabetic mouse model.METHODS: Forty 4-6wk BALB-C male mice weighing20-25 g were used. The study groups included: non-diabetic control(group 1), diabetic control(group 2),diabetic propranolol(group 3), and diabetic celecoxib(group 4). After induction of type 1 diabetes by streptozotocin, propranolol(10 μg) and celecoxib(200 μg dissolved in carboxymethylcellulose 0.5%) were injected periocularly. The ocular level of VEGF was measured in all the study groups using enzyme-linked immuno sorbent assay(ELISA) method. RESULTS: Ocular VEGF level was significantly increased(1.25 fold) in the diabetic control group when compared to the non-diabetic group one week after induction with streptozotocin(P =0.002). Both periocular propranolol and celecoxib significantly reduced ocular VEGF levels(P =0.047 and P <0.001, respectively). The effect was more pronounced with celecoxib. CONCLUSION: The periocular administration of propranolol and celecoxib can significantly reduce ocular VEGF levels in a diabetic mouse model. | Samar Nassiri Gholamreza Houshmand Mostafa Feghhi Alireza Kheirollah Mohammad Bahadoram Nariman Nassiri | 2016 | International Journal of Ophthalmology(English edition)2016，9，6： | 3 |

| 13 | AFM-compatible microfluidic platform for affinity- based capture and nanomechanical characterization of circulating tumor cells显示文摘Circulating tumor cells(CTCs)carried by the patient’s bloodstream are known to lead to the metastatic spread of cancer.It is becoming increasingly clear that an understanding of the nanomechanical characteristics of CTCs,such as elasticity and adhesiveness,represents advancements in tracking and monitoring cancer progression and metastasis.In the present work,we describe a combined microfluidic–atomic force microscopy(AFM)platform that uses antibody–antigen capture to routinely isolate and nanomechanically characterize CTCs present in blood samples from prostate cancer patients.We introduce the reversible assembly of a microfluidic device and apply refined and robust chemistry to covalently bond antibodies onto its glass substrate with high density and the desired orientation.As a result,we show that the device can efficiently capture CTCs from patients with localized and metastatic prostate cancer through anti-EpCAM,anti-PSA,and anti-PSMA antibodies,and it is suitable for AFM measurements of captured intact CTCs.When nanomechanically characterized,CTCs originating from metastatic cancer demonstrate decreased elasticity and increased deformability compared to those originating from localized cancer.While the average adhesion of CTCs to the AFM tip surface remained the same in both the groups,there were fewer multiple adhesion events in metastatic CTCs than there were in their counterparts.The developed platform is simple,robust,and reliable and can be useful in the diagnosis and prognosis of prostate cancer as well as other forms of cancer. | Muhammedin Deliorman Farhad K.Janahi Pavithra Sukumar Ayoub Glia Roaa Alnemari Samar Fadl Weiqiang Chen Mohammad A.Qasaimeh | 2020 | Microsystems & Nanoengineering2020，6，1： | 2 |
| 14 | Passiflora plastome sequencing reveals widespread genomic rearrangements显示文摘Although past studies have included Passiflora among angiosperm lineages with highly rearranged plastid genomes (plastomes),knowledge about plastome organization in the genus is limited.So far only one draft and one complete plastome have been published.Expanded sampling of Passiflora plastomes is needed to understand the extent of the genomic rearrangement in the genus,which is also unusual in having biparental plastid inheritance and plastome-genome incompatibility.We sequenced 15 Passiflora plastomes using either Illumina paired-end or shotgun cloning and Sanger sequencing approaches.Assembled plastomes were annotated using Dual Organellar GenoMe Annotator (DOGMA)and tRNAscan-SE.The Populus trichocarpa plastome was used as a reference to estimate genomic rearrangements in Passifloru by performing whole genome alignment in progressiveMauve.The phylogenetic distribution of rearrangements was plotted on the maximum likelihood tree generated from 64 plastid encoded protein genes.Inverted repeat (IR)expansion/contraction and loss of the two largest hypothetical open reading frames,ycf1 and ycf2,account for most plastome size variation,which ranges from 139 262 base pairs (bp)in P.biflora to 161 494 bp in P.pittieri.Passifloru plastomes have experienced numerous inversions,gene and intron losses along with multiple independent IR expansions and contractions resulting in a distinct organization in each of the three subgenera examined.Each Passiflora subgenus has a unique plastome structure in terms of gene content,order and size.The phylogenetic distribution of rearrangements shows that Passiflora has experienced widespread genomic changes,suggesting that such events may not be reliable phylogenetic markers. | Samar O.Rabah Bikash Shrestha Nahid H.Hajrah Mumdooh J.Sabir Hesham F.Alharby Mernan J.Sabir Alawiah M.Alhebshi Jamal S.M.Sabir Lawrence E.Gilbert Tracey A.Ruhlman Robert K.Jansen | 2019 | Journal of Systematics and Evolution2019，57，1： | 2 |
| 15 | Hydrothermal carbonization of agricultural residues:A case study of the farm residues-based biogas plants显示文摘Hydrothermal carbonization(HTC)of biomass is a promising method to produce carbonaceous materials.The work presented in this article addresses the application of hydrothermal carbonization(HTC)to produce a solid fuel named HTC-Biochar,whose characteristics are comparable to lignite coal.Biogas sludge(SD),maize silage(MS),and barley silage(BS)as a substrates were hydrothermally carbonized in a 1.5 L batch reactor at 200C for 6 h.The effect of mixing ratios of different substrates on HTC was investigated.Chemical compositions and combustion characteristics of hydro-chars obtained from mono-and co-carbonization were evaluated.Result showed that HTC increased carbon contents and higher heating values(HHV)by 1.4–14.4%and 13–36%,respectively.The evolution of the H/C and O/C atomic ratios indicated that dehydration and decarboxylation occurred during hydrothermal carbonization for all samples.Furthermore,a significant synergistic enhancement was observed for HHV and carbon content.A mixing ratio of 1:1 for BS and SD showed the best performance for co-HTC.In summary,hydrothermal co-carbonization is a promising strategy to tailor high-performance hydro-char for energy applications. | Samar Seyedsadr Rafat Al Afif Christoph Pfeifer | 2018 | Carbon Resources Conversion2018，1，1： | 2 |

| 17 | Week Ahead Electricity Power and Price Forecasting Using Improved DenseNet-121 Method显示文摘In the Smart Grid(SG)residential environment,consumers change their power consumption routine according to the price and incentives announced by the utility,which causes the prices to deviate from the initial pattern.Thereby,electricity demand and price forecasting play a significant role and can help in terms of reliability and sustainability.Due to the massive amount of data,big data analytics for forecasting becomes a hot topic in the SG domain.In this paper,the changing and non-linearity of consumer consumption pattern complex data is taken as input.To minimize the computational cost and complexity of the data,the average of the feature engineering approaches includes:Recursive Feature Eliminator(RFE),Extreme Gradient Boosting(XGboost),Random Forest(RF),and are upgraded to extract the most relevant and significant features.To this end,we have proposed the DensetNet-121 network and Support Vector Machine(SVM)ensemble with Aquila Optimizer(AO)to ensure adaptability and handle the complexity of data in the classification.Further,the AO method helps to tune the parameters of DensNet(121 layers)and SVM,which achieves less training loss,computational time,minimized overfitting problems and more training/test accuracy.Performance evaluation metrics and statistical analysis validate the proposed model results are better than the benchmark schemes.Our proposed method has achieved a minimal value of the Mean Average Percentage Error(MAPE)rate i.e.,8%by DenseNet-AO and 6%by SVM-AO and the maximum accurateness rate of 92%and 95%,respectively. | Muhammad Irfan Ali Raza Faisal Althobiani Nasir Ayub Muhammad Idrees Zain Ali Kashif Rizwan Abdullah Saeed Alwadie Saleh Mohammed Ghonaim Hesham Abdushkour Saifur Rahman Omar Alshorman Samar Alqhtani | 2022 | Computers, Materials & Continua2022，，9： | 2 |
