| 2 | Nitrogen in Relation to Photosynthetic Capacity and Accumulation of Osmoprotectant and Nutrients in Brassica Genotypes Grown Under Salt Stress显示文摘Different strategies of the application of nutrients are required to overcome the adverse effects of mustard (Brassica juncea L.) in response to NaCl stress. The objective of the present study was to determine if different added levels of nitrogen (N) in growth medium could alleviate the adverse effects of salt stress on photosynthetic capacity and accumulation of osmoprotectants and nutrients. 14 days mustard seedlings of salt-sensitive (cv. Chuutki) and salt-tolerant (cv. Radha) genotypes were fed with: (i) 0 mmol L-1 NaCl + 0 mg N kg-1 sand (control), (ii) 90 mmol L-1 NaCl + 30 mg N kg-1 sand, (iii) 90 mmol L-1 NaCl + 60 mg N kg-1 sand, (iv) 90 mmol L-1 NaCl + 90 mg N kg-1 sand and (v) 90 mmol L-1 NaCl + 120 mg N kg-1 sand. Under the condition of salinity stress, N application caused a significant ameliorative effect on both genotypes with respect to growth attributes [fresh weight (FW) and dry weight (DW)] and physio-biochemical parameters [percent water content (WC), net photosynthetic rate (PN), stomatal conductance (gs), total chlorophyll (Chl), carbonic anhydrase (CA) activity and malondialdehyde (MDA), nitrogen (N), potassium (K) and sodium (Na) contents, and K/Na ratio] and yield attributes (number of pods/plant, seeds/pod and seed yield/plant). The salt-tolerant genotype exhibited maximum value for growth, physio-biochemical and yield attributes at 60 mg N kg-1 sand than that of salt-sensitive genotype. These results suggest that application of N may ameliorate most of the attributes and prove to be a physiological remedy to increase the tolerance against the ill effects of salt stress in Brassicas. | Manzer H Siddiqui Firoz Mohammad M Nasir Khan Mohamed H Al-Whaibi Ali H A Bahkali | 2010 | Agricultural Sciences in China2010,9,5: | 14 |
| 3 | Evaluation of extracts and essential oil from Callistemon viminalis leaves:Antibacterial and antioxidant activities,total phenolic and flavonoid contents显示文摘Objective:To investigate antioxidant and antibacterial activities of Callistemon viminalis(C.viminalis)leaves.Methods:The essential oil of C.viminalis leaves obtained by hydrodistillation was analyzed by GC/MS.Different extracts were tested for total phenolic and flavonoid contents and in vitro antioxidant(DPPH assay)and antibacterial(agar disc diffusion and 96-well micro-plates methods)actives.Results:Fourteen components were identified in the essential oil,representing 98.94%of the total oil.The major components were 1,8-cineole(64.53%)andα-pinene(9.69%).Leaf essential oil exhibited the highest antioxidant activity of(88.60±1.51)%comparable to gallic acid,a standard compound[(80.00±2.12)%].Additionally,the biggest zone of inhibitions against the studied bacterial strains was observed by the essential oil when compared to the standard antibiotic(tetracycline).The crude methanol extract and ethyl acetate fraction had a significant antibacterial activity against the tested bacterial strains.Conclusions:It can be suggested that C.viminalis is a great potential source of antibacterial and antioxidant compounds useful for new antimicrobial drugs from the natural basis.The present study revealed that the essential oil as well as the methanol extracts and ethyl acetate fraction of C.viminalis leaves exhibited highly significant antibacterial activity against the tested bacterial strains. | Mohamed ZM Salem Hayssam M Ali Nader A El-Shanhorey Ahmed Abdel-Megeed | 2013 | Asian Pacific Journal of Tropical Medicine2013,6,10: | 14 |
| 4 | Energy-efficient Virtual Machine Allocation Technique Using Flower Pollination Algorithm in Cloud Datacenter:A Panacea to Green Computing显示文摘Cloud computing has attracted significant interest due to the increasing service demands from organizations offloading computationally intensive tasks to datacenters.Meanwhile,datacenter infrastructure comprises hardware resources that consume high amount of energy and give out carbon emissions at hazardous levels.In cloud datacenter,Virtual Machines(VMs)need to be allocated on various Physical Machines(PMs)in order to minimize resource wastage and increase energy efficiency.Resource allocation problem is NP-hard.Hence finding an exact solution is complicated especially for large-scale datacenters.In this con text,this paper proposes an Energy-oriented Flower Pollination Algorithm(E-FPA)for VM allocation in cloud datacenter environments.A system framework for the scheme was developed to enable energy-oriented allocation of various VMs on a PM.The allocation uses a strategy called Dynamic Switching Probability(DSP).The framework finds a near optimal solution quickly and balances the exploration of the global search and exploitation of the local search.It considers a processor,storage,and memory constraints of a PM while prioritizing energy-oriented allocation for a set of VMs.Simulations performed on MultiRecCloudSim utilizing planet workload show that the E-FPA outperforms the Genetic Algorithm for Power-Aware(GAPA)by 21.8%,Order of Exchange Migration(OEM)ant colony system by 21.5%,and First Fit Decreasing(FFD)by 24.9%.Therefore,E-FPA significantly improves datacenter performance and thus,enhances environmental sustainability. | Mohammed Joda Usman Abdul Samad Ismail Hassan Chizari Gaddafi Abdul-Salaam Ali Muhammad Usman Abdulsalam Yau Gital Omprakash Kaiwartya Ahmed Aliyu | 2019 | Journal of Bionic Engineering2019,16,2: | 13 |
| 5 | Clinicopathological features and surgical outcome of patients with fibrolamellar hepatocellular carcinoma(experience with 22 patients over a 15-year period)显示文摘AIM To evaluate the clinicopathological features and the surgical outcomes of patients with fibrolamellar hepato-cellular carcinoma(FL-HCC)over a 15-year period. METHODS This is a retrospective study including 22 patients with a pathologic diagnosis of FL-HCC who underwent hepatectomy over a 15-year period. Tumor characteristics,survival and recurrence were evaluated. RESULTS There were 11 male and 11 female with a median age of 29 years(range from 21 to 58 years). Two(9%)patients had hepatitis C viral infection and only 2(9%)patients had alpha-fetoprotein level > 200 ng/m L. The median size of the tumors was 12 cm(range from 5-20 cm). Vascular invasion was detected in 5(23%)patients. Four(18%)patients had lymph node metastases. The median follow up period was 42 mo and the 5-year survival was 65%. Five(23%)patients had a recurrent disease,4 of them had a second surgery with 36 mo median time interval. Vascular invasion is the only significant negative prognostic factor CONCLUSION FL-HCC has a favorable prognosis than common HCC and should be suspected in young patients with non cirrhotic liver. Aggressive surgical resection should be done for all patients. Repeated hepatectomy should be considered for these patients as it has a relatively indolent course. | Mohamed Abdel Wahab Ehab El Hanafy Ayman El Nakeeb Mahmoud Abdelwahab Ali | 2017 | World Journal of Gastrointestinal Surgery2017,9,2: | 12 |
| 6 | Real time endoscopic ultrasound elastography and strain ratio in the diagnosis of solid pancreatic lesions显示文摘AIM To evaluate the accuracy of the elastography score combined to the strain ratio in the diagnosis of solid pancreatic lesions(SPL). METHODS A total of 172 patients with SPL identified by endoscopic ultrasound were enrolled in the study to evaluate the efficacy of elastography and strain ratio in differentiating malignant from benign lesions. The semi quantitative score of elastography was represented by the strain ratio method. Two areas were selected, area(A) representing the region of interest and area(B) representing the normal area. Area(B) was then divided by area(A). Sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV), and accuracy were calculated by comparing diagnoses made by elastography, strain ratio and final diagnoses.RESULTS SPL were shown to be benign in 49 patients and malignant in 123 patients. Elastography alone had a sensitivity of 99%, a specificity of 63%, and an accuracy of 88%, a PPV of 87% and an NPV of 96%. The best cut-off level of strain ratio to obtain the maximal area under the curve was 7.8 with a sensitivity of 92%, specificity of 77%, PPV of 91%, NPV of 80% and an accuracy of 88%. Another estimated cut off strain ratio level of 3.8 had a higher sensitivity of 99% and NPV of 96%, but with less specificity, PPV and accuracy 53%, 84% and 86%, respectively. Adding both elastography to strain ratio resulted in a sensitivity of 98%, specificity of 77%, PPV of 91%, NPV of 95% and accuracy of 92% for the diagnosis of SPL. CONCLUSION Combining elastography to strain ratio increases the accuracy of the differentiation of benign from malignant SPL. | Hussein Okasha Shaimaa Elkholy Ramy El-Sayed Mohamed-Naguib Wifi Mohamed El-Nady Walid El-Nabawi Waleed A El-Dayem Mohamed I Radwan Ali Farag Yahya El-sherif Emad Al-Gemeie Ahmed Salman Mohamed El-Sherbiny Ahmed El-Mazny Reem E Mahdy | 2017 | World Journal of Gastroenterology2017,23,32: | 11 |
| 7 | Predictors of long term survival after hepatic resection for hilar cholangiocarcinoma:A retrospective study of 5-year survivors显示文摘AIM:To determine predictors of long term survival after resection of hilar cholangiocarcinoma(HC) by comparing patients surviving > 5 years with those who survived < 5 years.METHODS:This is a retrospective study of patients with pathologically proven HC who underwent surgical resection at the Gastroenterology Surgical Center,Mansoura University,Egypt between January 2002 and April 2013.All data of the patients were collected from the medical records.patients were divided into two groups according to their survival:patients surviving less than 5 years and those who survived > 5 years.RESULTS:There were 34(14%) long term survivors(5 year survivors) among the 243 patients.Fiveyear survivors were younger at diagnosis than those surviving less than 5 years(mean age,50.47 ± 4.45 vs 54.59 ± 4.98,p = 0.001).Gender,clinical presentation,preoperative drainage,preoperative serum bilirubin,albumin and serum glutamic-pyruvic transaminase were similar between the two groups.The level of CA 19-9 was significantly higher in patients surviving < 5 years(395.71 ± 31.43 vs 254.06 ± 42.19,p = 0.0001).Univariate analysis demonstrated nine variables to be significantly associated with survival > 5 year,includingyoung age(p = 0.001),serum CA19-9(p = 0.0001),non-cirrhotic liver(p = 0.02),major hepatic resection(p = 0.001),caudate lobe resection(p = 0.006),well differentiated tumour(p = 0.03),lymph node status(0.008),R0 resection margin(p = 0.0001) and early postoperative liver cell failure(p = 0.02).CONCLUSION:Liver status,resection of caudate lobe,lymph node status,R0 resection and CA19-9 were demonstrated to be independent risk factors for long term survival. | Mohamed Abd El Wahab Ayman El Nakeeb Ehab El Hanafy Ahmad M Sultan Ahmed Elghawalby Waleed Askr Mahmoud Ali Mohamed Abd El Gawad Tarek Salah | 2016 | World Journal of Gastrointestinal Surgery2016,8,6: | 10 |
| 8 | Medical management of patients after bariatric surgery: Principles and guidelines显示文摘Obesity is a major and growing health care concern. Large epidemiologic studies that evaluated the relationship between obesity and mortality, observed that a higher body-mass index(BMI) is associated with increased rate of death from several causes, among them cardiovascular disease; which is particularly true for those with morbid obesity. Being overweight was also associated with decreased survival in several studies. Unfortunately, obese subjects are often exposed to public disapproval because of their fatness which significantly affects their psychosocial behavior. All obese patients(BMI ≥ 30 kg/m2) should receive counseling on diet, lifestyle, exercise and goals for weight management. Individuals with BMI ≥ 40 kg/m2 and those with BMI > 35 kg/m2 with obesity-related comorbidities; who failed diet, exercise, and drug therapy, should be considered for bariatric surgery. In current review article, we will shed light on important medical principles that each surgeon/gastroenterologist needs to know about bariatric surgical procedure, with special concern to the early post operative period. Additionally, we will explain the common complications that usually follow bariatric surgery and elucidate medical guidelines in their management. For the first 24 h after the bariatric surgery, the postoperative priorities include pain management, leakage, nausea and vomiting, intravenous fluid management, pulmonary hygiene, and ambulation. Patients maintain a low calorie liquid diet for the first few postoperative days that is gradually changed to soft solid food diet within two or three weeks following the bariatric surgery. Later, patients should be monitored for postoperative complications. Hypertension, diabetes, dumping syndrome, gastrointestinal and psychosomatic disorders are among the most important medical conditions discussed in this review. | Abd Elrazek Mohammad Ali Abd Elrazek Abduh Elsayed Mohamed Elbanna Shymaa E Bilasy | 2014 | World Journal of Gastrointestinal Surgery2014,6,11: | 9 |
| 9 | Anti-wear properties evaluation of frictional sliding interfaces in automobile engines lubricated by copper/graphene nanolubricants显示文摘Owing to the significance of improving fuel economy, reducing emissions, and extending the durability of engine components, this study focused on the tribological performance of nano-additives. In this study, copper (Cu) and graphene (Gr) nanomaterials were dispersed in a fully formulated engine oil (5W-30) with different concentrations. The tribological trials were investigated under various speeds and loads, utilizing a reciprocating tribometer to mimic the ring/liner interfaces in the engine. The frictional surface morphologies were com-prehensively analyzed using electron probe X-ray microanalysis (EPMA), field emission scanning electron microscopy (FESEM), energy dispersive spectrometer (EDS), and three dimensional (3D) surface profilometry to explore the mechanisms responsible for improving the tribological performance of the frictional sliding parts in the engine. The tribological test results illustrated that lubrication by nano-additives reduced the wear rate (WR) and friction coefficient (COF) by 25%–30% and 26.5%–32.6%, respectively, as compared with 5W-30. The results showed that this is a promising approach for increasing the durability and lifespan of frictional sliding components and fuel economy in automobile engines. | Mohamed Kamal Ahmed ALI Xianjun HOU Mohamed AAABDELKAREEM | 2020 | Friction2020,8,5: | 9 |

| 11 | Bulk and bubble-scale experimental studies of influence of nanoparticles on foam stability显示文摘Influence of silicon oxide(SiO_2) and aluminum oxide(Al_2O_3) nanoparticles on the stability of nanoparticles and sodium dodecyl sulfate(SDS) mixed solution foams was studied at bulk and bubble-scale. Foam apparent viscosity was also determined in Hele-Shaw cell In order to investigate the foam performance at static and dynamic conditions. Results show that the maximum adsorption of surfactant on the nanoparticles occurs at 3 wt% surfactant concentration. Foam stability increases while the foamability decreases with the increasing nanoparticle concentration. However, optimum nanoparticle concentration corresponding to maximum foam stability was obtained at 1.0 wt% nanoparticle concentration for the hydrophilic SiO_2/SDS and Al_2O_3/SDS foams. Foam performance was enhanced with increasing nanoparticles hydrophobicity. Air-foams were generally more stable than CO_2 foams.Foam apparent viscosity increased in the presence of nanoparticles from 20.34 mPa·s to 84.84 mPa·s while the film thickness increased from 27.5 μm to 136 μm. This study suggests that the static and dynamic stability of conventional foams could be improved with addition of appropriate concentration of nanoparticles into the surfactant solution. The nanoparticles improve foam stability by their adsorption and aggregation at the foam lamellae to increase film thickness and dilational viscoelasticity. This prevents liquid drainage and film thinning and improves foam stability both at the bulk and bubble scale. | Nurudeen Yekeen Ahmad Kamal Idris Muhammad A.Manan Ali Mohamed Samin Abdul Rahim Risal Tan Xin Kun | 2017 | Chinese Journal of Chemical Engineering2017,25,3: | 9 |

| 14 | Hepatitis C virus:A global view显示文摘Hepatitis C virus(HCV) is a global challenge; 130-175 million are chronically infected. Over 350000 die each year from HCV. Chronic HCV is the primary cause of cirrhosis, hepatocellular carcinoma(HCC), and end-stage liver disease. Management of chronic HCV is aimed at preventing cirrhosis, reducing the risk of HCC, and treating extra hepatic complications. New treatments for chronic HCV has been devoted based on direct-acting antivirals, as pegylated interferon(peginterferon) is responsible for many side effects and limits treatment access. Sofosbuvir is the first compound to enter the market with Peginterferon-free combination regimens. | Amal Ahmed Mohamed Tamer A Elbedewy Magdy El-Serafy Naglaa El-Toukhy Wesam Ahmed Zaniab Ali El Din | 2015 | World Journal of Hepatology2015,7,26: | 7 |
| 15 | 863 genomes reveal the origin and domestication of chicken显示文摘Despite the substantial role that chickens have played in human societies across the world,both the geographic and temporal origins of their domestication remain controversial.To address this issue,we analyzed 863 genomes from a worldwide sampling of chickens and representatives of all four species of wild jungle fowl and each of the five subspecies of red jungle fowl(RJF).Our study suggests that domestic chickens were initially derived from the RJF subspecies Gallus gallus spadiceus whose present-day distribution is predominantly in southwestern China,northern Thailand and Myanmar.Following their domestication,chickens were translocated across Southeast and South Asia where they interbred locally with both RJF subspecies and other jungle fowl species.In addition,our results show that the White Leghorn chicken breed possesses a mosaic of divergent ancestries inherited from other subspecies of RJF.Despite the strong episodic gene flow from geographically divergent lineages of jungle fowls,our analyses show that domestic chickens undergo genetic adaptations that underlie their unique behavioral,morphological and reproductive traits.Our study provides novel insights into the evolutionary history of domestic chickens and a valuable resource to facilitate ongoing genetic and functional investigations of the world's most numerous domestic animal. | Ming-Shan Wang Mukesh Thakur Min-Sheng Peng Yu Jiang Laurent Alain Francois Frantz Ming Li Jin-Jin Zhang Sheng Wang Joris Peters Newton Otieno Otecko Chatmongkon Suwannapoom Xing Guo Zhu-Qing Zheng Ali Esmailizadeh Nalini Yasoda Hirimuthugoda Hidayat Ashari Sri Suladari Moch Syamsul Arifin Zein Szilvia Kusza Saeed Sohrabi Hamed Kharrati-Koopaee Quan-Kuan Shen Lin Zeng Min-Min Yang Ya-Jiang Wu Xing-Yan Yang Xue-Mei Lu Xin-Zheng Jia Qing-Hua Nie Susan Joy Lamont Emiliano Lasagna Simone Ceccobelli Humpita Gamaralalage Thilini Nisanka Gunwardana Thilina Madusanka Senasige Shao-Hong Feng Jing-Fang Si Hao Zhang Jie-Qiong Jin Ming-Li Li Yan-Hu Liu Hong-Man Chen Cheng Ma Shan-Shan Dai Abul Kashem Fazlul Haque Bhuiyan Muhammad Sajjad Khan Gamamada Liyanage Lalanie Pradeepa Silva Thi-Thuy Le Okeyo Ally Mwai Mohamed Nawaz Mohamed Ibrahim Megan Supple Beth Shapiro Olivier Hanotte Guojie Zhang Greger Larson Jian-Lin Han Dong-Dong Wu Ya-Ping Zhang | 2020 | Cell Research2020,30,8: | 7 |
| 16 | Performance analysis of space-shift keying over negative-exponential and log-normal FSO channels显示文摘The average bit-error rate(ABER) performance of free-space optical(FSO) communication links is investigated for space-shift keying(SSK) over log-normal and negative-exponential atmospheric turbulence channels. SSK is compared with repetition codes and a single-input single-output system using multiple pulse amplitude modulations. Simulation results show that the signal-to-noise ratio gain of SSK largely increases with greater spectral efficiencies and/or higher turbulence effects. A tight bound for ABER is derived based on an exact moment generation function(MGF) for negative-exponential channel and an approximate MGF for log-normal channel.Finally, extensive Monte Carlo simulations are run to validate the analytical analysis. | Mohamed Abaza Raed Mesleh Ali Mansour el-Hadi Aggoune | 2015 | Chinese Optics Letters2015,13,5: | 6 |
| 17 | Emotion processing in Parkinson's disease: a blood oxygenation level-dependent functional magnetic resonance imaging study显示文摘Parkinson's disease is a neurodegenerative disorder caused by loss of dopamine neurons in the substantia nigra pars compacta. Tremor, rigidity, and bradykinesia are the major symptoms of the disease. These motor impairments are often accompanied by affective and emotional dysfunctions which have been largely studied over the last decade. The aim of this study was to investigate emotional processing organization in the brain of patients with Parkinson's disease and to explore whether there are differences between recognition of different types of emotions in Parkinson's disease. We examined 18 patients with Parkinson's disease(8 men, 10 women) with no history of neurological or psychiatric comorbidities. All these patients underwent identical brain blood oxygenation level-dependent functional magnetic resonance imaging for emotion evaluation. Blood oxygenation level-dependent functional magnetic resonance imaging results revealed that the occipito-temporal cortices, insula, orbitofrontal cortex, basal ganglia, and parietal cortex which are involved in emotion processing, were activated during the functional control. Additionally, positive emotions activate larger volumes of the same anatomical entities than neutral and negative emotions. Results also revealed that Parkinson's disease associated with emotional disorders are increasingly recognized as disabling as classic motor symptoms. These findings help clinical physicians to recognize the emotional dysfunction of patients with Parkinson's disease. | Mohammed Benzagmout Sa?d Boujraf Badreeddine Alami Hassane Ali Amadou Halima El Hamdaoui Amine Bennani Mounir Jaafari Ismail Rammouz Mustapha Maaroufi Rabia Magoul Driss Boussaoud | 2019 | Neural Regeneration Research2019,14,4: | 6 |

| 19 | Evaluation of protective effect of cactus pear seed oil(Opuntia ficusincida L. MILL.) against alloxan-induced diabetes in mice显示文摘Objective: To evaluate the in vitro antioxidant power of cactus pear seed oil [Opuntia ficusincida L. MILL.(CPSO)] and its protective effect against chemically induced diabetes mellitus in mice. Methods: The in vitro antioxidant effect of CPSO was evaluated using 2,2-diphenyl-1-picrylhydrazyl(DPPH) scavenging assay. The preventive effect was conducted on Swiss albino mice treated with CPSO(2 m L/kg, per os), before and after a single intraperitoneal alloxan administration(100 mg/kg). Survival rate, body weight and fasting blood glucose were measured and histopathological analysis of pancreas was performed to evaluate alloxaninduced tissue injuries. Results: CPSO exhibited an antioxidant effect in DPPH scavenging assay. Moreover, the administration of CPSO(2 m L/kg) significantly attenuated alloxaninduced death and hyperglycemia(P<0.001) in treated mice. Morphometric study of pancreas revealed that CPSO significantly protected islets of langerhans against alloxan induced-tissue alterations. Conclusions: Based on theses results, CPSO can prevent alloxan-induced-diabetes by quenching free radicals produced by alloxan and inhibiting tissue injuries in pancreatic β-cells. | Berraaouan Ali Ziyyat Abderrahim Mekhfi Hassane Legssyer Abdelkhaleq Aziz Mohammed Bnouham Mohamed | 2015 | Asian Pacific Journal of Tropical Medicine2015,8,7: | 6 |
