| 2 | Response to endoscopic therapy for biliary anastomotic strictures in deceased versus living donor liver transplantation显示文摘BACKGROUND:Endoscopic therapy has been successful in the management of biliary complications after both deceased donor liver transplantation(DDLT) and living donor liver transplantation(LDLT).LDLT is thought to be associated with higher rates of biliary complications,but there are few studies comparing the success of endoscopic management of anastomotic strictures between the two groups.This study aims to compare our experience in the endoscopic management of anastomotic strictures in DDLT versus LDLT.METHODS:This is a retrospective database review of all liver transplant patients undergoing endoscopic retrograde cholangiopancreatography(ERCP) after liver transplantation.The frequency of anastomotic stricture and the time to develop and to resolve anastomotic stricture were compared between DDLT and LDLT.The response of anastomotic stricture to endoscopic therapy was also analyzed.RESULTS:A total of 362 patients underwent liver transplantation between 2003 and 2011,with 125 requiring ERCP to manage biliary complications.Thirty-three(9.9%) cases of DDLT and 8(27.6%) of LDLT(P=0.01) were found to have anastomotic stricture.When comparing DDLT and LDLT,there was no difference in the mean time to the development of anastomotic strictures(98±17 vs 172±65 days,P=0.11),likelihood of response to ERCP [22(66.7%) vs 6(75.0%),P=0.69],mean time to the resolution of anastomotic strictures(268±77 vs 125±37 days,P=0.34),and the number of ERCPs required to achieve resolution(3.9±0.4 vs 4.7±0.9,P=0.38).CONCLUSIONS:Endoscopic therapy is effective in the majority of biliary complications relating to liver transplantation.Anastomotic strictures occur more frequently in LDLT compared with DDLT,with equivalent endoscopic treatment response and outcomes for both groups. | Calvin HY Chan Fergal Donnellan Michael F Byrne Alan Coss Mazhar Haque Holly Wiesenger Charles H Scudamore Urs P Steinbrecher Alan A Weiss Eric M Yoshida | 2013 | Hepatobiliary & Pancreatic Diseases International2013,12,5: | 7 |
| 3 | Quercetin modulates iron homeostasis and iNOS expression of splenic macrophages in a rat model of iron deficiency anemia显示文摘Iron deficiency anemia is one of the most common micronutrient deficient conditions around the globe with various consequences,including the weakened immune system.Quercetin is widely distributed bioflavonoid;it has been debated for its dual roles in iron regulation.Quercetin-iron interaction in the body is a complex mechanism which has not been completely understood.The present study aimed to investigate the effect of quercetin on iron supplementation in iron deficiency anemia and on i NOS expression in splenic macrophages.The rat model of iron deficiency anemia was induced by feeding low iron diet to weanling rats for 20 days.The animals were then administered with ferrous sulfate,quercetin,and their combination for 30 days.Blood parameters,histopathological analysis,iron storage,CD68,i NOS and SLC40 expression in rat spleen were investigated.Our results showed that quercetin regulated iron absorption,despite SLC40 down-expression,indicating possible alternate route of iron transport,and that quercetin modulated i NOS production in splenic macrophages.. | Maryam Mazhar Nurul Kabir Shabana U Simjee | 2018 | Chinese Journal of Natural Medicines2018,16,8: | 4 |

| 5 | Comments on “Distillability sudden death in qutrit qutrit systems under thermal reservoirs”显示文摘In a recent paper(2012 Chin.Phys.B 21 084205),the authors studied the problem of distillability sudden death.We find that their equation of motion is incorrect and consequently the rest of the paper is wrong.Even apart from starting with a wrong equation of motion,their description of the phenomenon of distillability sudden death is totally misleading and needs to be rectified.To this aim,we show that certain initially prepared free-entangled states become bound-entangled in a finite time under thermal reservoirs.Moreover,in contrast with zero-temperature reservoirs,simple local unitary transformations cannot completely avoid distillability sudden death. | Mazhar Ali | 2014 | Chinese Physics B2014,23,9: | 3 |
| 6 | Determination of Trace Amounts of Nickel (Ⅱ) by Graphite Furnace Atomic Absorption Spectrometry Coupled with Cloud Point Extraction显示文摘A new method based on the cloud point extraction(CPE) for separation and preconcentration of nickel(Ⅱ) and its subsequent determination by graphite furnace atomic absorption spectrometry(GFAAS) was proposed, 8-hydroxyquinoline and Triton X-100 were used as the ligand and surfactant respectively. Nickel(Ⅱ) can form a hy-drophobic complex with 8-hydroxyquinoline, the complex can be extracted into the small volume surfactant rich phase at the cloud point temperature(CPT) for GFAAS determination. The factors affecting the cloud point extraction, such as pH, ligand concentration, surfactant concentration, and the incubation time were optimized. Under the optimal conditions, a detection limit of 12 ng/L and a relative standard deviation(RSD) of 2.9% were obtained for Ni(Ⅱ) determination. The enrichment factor was found to be 25. The proposed method was successfully applied to the determination of nickel(Ⅱ) in certified reference material and different types of water samples and the recovery was in a range of 95%―103%. | SHAH Syed Mazhar WANG Hao-nan SU Xing-guang | 2011 | Chemical Research in Chinese Universities2011,27,3: | 3 |

| 8 | Effect of gravistimulation on amino acid profile of pea,rice,corn,wheat during early growth stages显示文摘The amino acids are one of the major cellular components of plants,which are involved in different metabolic pathways.In present study,effect of artificial gravistimulation on amino acid profiles of pea,rice,corn,wheat during early growth stages was investigated.One-axis clinostat was used for gravistimulation application,which was applied at embryonic stage.Amino acid profile was measured in 10-days old seedlings of pea,rice,corn and wheat cultivars.The effect of clinostat rotation was also evaluated under salt stress and MS medium supplement.Germinated pea,rice,corn and wheat seedlings were grown under the gravity condition for specific time interval.Corn and wheat seeds showed slowgermination as compared to pea and rice cultivars.The rate of amino acid formation under gravity condition was significantly higher than control(un-treated seedling).The variation in amino acid profile of pea,rice,corn and wheat cultivars vary deferentially.Results revealed that gravistimulation applied through clinostat has positive effect on amino acid profile in plant tissue and future studies should be focused on growth,biochemical,physiological at lateral stages of growth. | Raghad S.Mouhamad Munawar Iqbal MAfzal Qamar Lamiaa A.Mutlag Ibrahim B.Razaq Mazhar Abbas Fida Hussain | 2016 | Information Processing in Agriculture2016,3,4: | 2 |
| 9 | In vitro larvicidal potential against Anopheles stephensi and antioxidative enzyme activities of Ginkgo biloba,Stevia rebaudiana and Parthenium hysterophorous显示文摘Objective:To investigate in vitro larvicidal and antioxidant enzymes potential of the medicinal plants Ginkgo biloba(G.biloba),Stevia rebaudiana(S.rebaudiana) and Parthenium hysterophorous(P.hysterophorous) against Anopheles stephensi(An.stephensi) 4th instars larvae. Methods:For evaluation of larvicidal potential,the ethanolic,methanolic and dichloromethane leaves extracts of three different plants were used in dose-dependent experiments in two media, while the antioxidant enzymes activities were investigated using four different methods viz., superoxide dismutase,peroxidase,ascorbate and catalase.Results:An.stephensi has developed resistance to various synthetic insecticides,making its control increasingly difficult.The comparative performance of ethanolic extracts(65%-90%) was found better than the methanolic extract(70%-87%) and dichloromethane extract(60%-70%).Among the three plants extracts tested in two media,S.rebaudiana exhibited higher larvicidal activity with LC50(24 h) in methanolic extract than P.hysterophorous and G.biloba.G.biloba and P.hysterophorous exhibited the strongest antioxidative enzymes activity and S.rebaudiana were less active and no significant difference was observed.Conclusions:These three plants exhibit larvicidal potential and can be further used for vector control alternative to synthetic insecticide due to eco-friendly and diseases control,furthermore these plant species have potent antioxidative enzyme activities, therefore,making them strong natural candidate particularly for diseases which are caused due to free radicals. | Nisar Ahmad Hina Fazal Bilal H Abbasi Mazhar Iqbal | 2011 | Asian Pacific Journal of Tropical Medicine2011,4,3: | 2 |
| 10 | Effects of different irrigation frequencies and incorporation of rice straw on yield and water productivity of wheat crop显示文摘The current rapid increase in irrigation water consumption is considered unsustainable and threatens the world food production.Therefore,it is mandatory to promote modern techniques and to manage existing conventional irrigation methods.The present study was attempted to determine the effects of different irrigation frequencies and rice straw incorporation rates on yield and water productivity of the wheat crop.The experiment was arranged with randomize complete block design involving nine treatments(RS 0 I 7,RS 0 I 15,RS 0 I 22,RS 1 I 7,RS 1 I 15,RS 1 I 22,RS 2 I 7,RS 2 I 15 and RS 2 I 22)under three replications.Results exposed that the incorporation of rice straw with different irrigation frequencies significantly improved physico-chemical properties of soil.Moreover,soil bulk density,infiltration rate,pH,electrical conductivity significantly decreased and soil porosity significantly increased under all treatments.Furthermore,maximum crop yield and crop water productivity of 7706.4 kg/hm 2 and 1.92 kg/m 3 respectively were found under RS 1 I 15 treatment.Based on experimental results it can be concluded that irrigation frequency and incorporation of rice straw had significant effects on the physico-chemical properties of soil,total grain yield and water productivity of the wheat crop.However,this study suggested that the wheat crop yield and water productivity could be increased by incorporating 1 t/hm 2 rice straw with 15 d of irrigation frequency. | Mazhar Hussain Tunio Jianmin Gao Mashooque Ali Talpur Imran Ali Lakhiar Farman Ali Chandio Sher Ali Shaikh Kashif Ali Solangi | 2020 | International Journal of Agricultural and Biological Engineering2020,13,1: | 2 |
| 11 | Hepatitis C virus prevalence and genotype distribution inPakistan:Comprehensive review of recent data显示文摘Hepatitis C virus(HCV) is endemic in Pakistan and its burden is expected to increase in coming decades owing mainly to widespread use of unsafe medical procedures. The prevalence of HCV in Pakistan has previously been reviewed. However, the literature search conducted here revealed that at least 86 relevant studies have been produced since the publication of these systematic reviews. A revised updated analysis was therefore needed in order to integrate the fresh data. A systematic review of data published between 2010 and 2015 showed that HCV seroprevalence among the general adult Pakistani population is 6.8%, while active HCV infection was found in approximately 6% of the population. Studies included in this review have also shown extremely high HCV prevalence in rural and underdeveloped peri-urban areas(up to 25%), highlighting the need for an increased focus on this previously neglected socioeconomic stratum of the population. While a 2.45% seroprevalence among blood donors demands immediate measures to curtail the risk of transfusion transmitted HCV, a very high prevalence in patients attending hospitals with various non-liver disease related complaints(up to 30%) suggests a rise in the incidence of nosocomial HCV spread. HCV genotype 3a continues to be the most prevalent subtype infecting people in Pakistan(61.3%). However, recent years have witnessed an increase in the frequency of subtype 2a in certain geographical sub-regions within Pakistan. In Khyber Pakhtunkhwa and Sindh provinces, 2a was the second most prevalent genotype(17.3% and 11.3% respectively). While the changing frequency distribution of various genotypes demands an increased emphasis on research for novel therapeutic regimens, evidence of high nosocomial transmission calls for immediate measures aimed at ensuring safe medical practices. | muhammad umer mazhar iqbal | 2016 | World Journal of Gastroenterology2016,22,4: | 2 |
| 12 | Total phenolic,chromium contents and antioxidant activity of raw and processed sugars显示文摘Processing improves the visual quality of food;however,the ingredient and nutritional values may alter.In present study,the sugar samples(refined,raw,gur(Jaggery/jaggeree)and molasses)were collected from 20 different agro-climatic regions of Pakistan and analyzed for the chromium concentration,total phenolic and antioxidant activity,in order to evaluate the processing effect.The concentration of Cr was determined by digestion method using atomic absorption spectrophotometer,while antioxidant activity was determined by DPPH(1,1-diphenyl-2-picrylhydrazyl)and reducing power.It was observed that chromium content in Jaggery was 74%higher than raw sugar,while molasses showed 21.27%higher concentration versus jaggery.The total phenolic contents were found considerably higher in molasses(3751 lg GAE/g)followed by Jaggery(3285 lg GAE/g),raw sugar(27.75 lg GAE/g)and refined sugar(23.81 lg GAE/g).The DPPH scavenging activity and reducing power was also found dependent to sugar type.Form results,it can be concluded that processing significantly affected the chromium contents,total phenolics and antioxidant activity. | Munawar Iqbal MAfzal Qamar Tanveer H.Bokhari Mazhar Abbas Fida Hussain Nasir Masood Ali Keshavarzi Naseem Qureshih Arif Nazir | 2017 | Information Processing in Agriculture2017,4,1: | 2 |

| 14 | Reverse vaccinology assisted designing of multiepitope-based subunit vaccine against SARS-CoV-2显示文摘Background:Coronavirus disease 2019(COVID-19)linked with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)cause severe illness and life-threatening pneumonia in humans.The current COVID-19 pandemic demands an effective vaccine to acquire protection against the infection.Therefore,the present study was aimed to design a multiepitope-based subunit vaccine(MESV)against COVID-19.Methods:Structural proteins(Surface glycoprotein,Envelope protein,and Membrane glycoprotein)of SARS-CoV-2 are responsible for its prime functions.Sequences of proteins were downloaded from GenBank and several immunoinformatics coupled with computational approaches were employed to forecast B-and T-cell epitopes from the SARS-CoV-2 highly antigenic structural proteins to design an effective MESV.Results:Predicted epitopes suggested high antigenicity,conserveness,substantial interactions with the human leukocyte antigen(HLA)binding alleles,and collective global population coverage of 88.40%.Taken together,276 amino acids long MESV was designed by connecting 3 cytotoxic T lymphocytes(CTL),6 helper T lymphocyte(HTL)and 4 B-cell epitopes with suitable adjuvant and linkers.The MESV construct was non-allergenic,stable,and highly antigenic.Molecular docking showed a stable and high binding affinity of MESV with human pathogenic toll-like receptors-3(TLR3).Furthermore,in silico immune simulation revealed significant immunogenic response of MESV.Finally,MEV codons were optimized for its in silico cloning into the Escherichia coli K-12 system,to ensure its increased expression.Conclusion:The MESV developed in this study is capable of generating immune response against COVID-19.Therefore,if designed MESV further investigated experimentally,it would be an effective vaccine candidate against SARS-CoV-2 to control and prevent COVID-19. | Muhammad Tahir ul Qamar Farah Shahid Sadia Aslam Usman Ali Ashfaq Sidra Aslam Israr Fatima Muhammad Mazhar Fareed Ali Zohaib Ling-Ling Chen | 2020 | Infectious Diseases of Poverty2020,9,5: | 2 |
| 15 | Endoscopic ultrasound-fine needle injection for oncological therapy显示文摘The minimal invasiveness and precision of endoscopicultrasound(EUS) has lead to both its widespread use as a diagnostic and staging modality for gastrointestinal and pancreaticobiliary malignancies, and to its expand-ing role as a therapeutic modality. EUS-guided celiac plexus neurolysis is now a well-accepted modality for palliation of pain in patients with pancreatic cancer. EUS-guided ablation, brachytherapy, fiducial marker placement, and antitumor agent injection have been described as methods of performing minimally invasive oncological therapy. EUS-fine needle injection may be performed as adjunctive, alternative, or palliative treatment. This review summarizes the studies to date that have described these methods. A literature search using the Pub Med/MEDLINE databases was performed. While most published studies to date are limited with disappointing outcomes, the concept of a role of EUS in oncological therapy seems promising. | Jeremy Kaplan Amaara Khalid Natalie Cosgrove Ayesha Soomro Syed Mohsin Mazhar Ali A Siddiqui | 2015 | World Journal of Gastrointestinal Oncology2015,7,12: | 2 |

| 19 | Papaya Ring Spot Virus:An Understanding of a Severe Positive-Sense Single Stranded RNA Viral Disease and Its Management显示文摘Viral diseases have been studied in-depth for reducing quality,yield,health and longevity of the fruit,to highlight the economic losses.Positive-sense single-stranded RNA viruses are more devastating among all viruses that infect fruit trees.One of the best examples is papaya ringspot virus(PRSV).It belongs to the genus Potyvirus and it is limited to cause diseases on the family Chenopodiaceae,Cucurbitaceae and Caricaceae.This virus has a serious threat to the production of papaya,which is famous for its high nutritional and pharmaceutical values.The plant parts such as leaves,latex,seeds,fruits,bark,peel and roots may contain the biological compound that can be isolated and used in pharmaceutical industries as a disease control.Viral disease symptoms consist of vein clearing and yellowing of young leaves.Distinctive ring spot patterns with concentric rings and spots on fruit reduce its quality and taste.The virus has two major strains P and W.The former cause disease in papaya and cucurbits while the later one in papaya.Virion comprises 94.4%protein,including a 36 kDa coat protein which is a component responsible for a non-persistent transmission through aphids,and 5.5%nucleic acid.Cross protection,development of transgenic crops,exploring the resistant sources and induction of pathogen derived resistance have been recorded as effective management of PRSV.Along with these practices reduced aphid population through insecticides and plant extracts have been found ecofriendly approaches to minimize the disease incidence.Adoption of transgenic crops is a big challenge for the success of disease resistant papaya crops.The aim of this review is to understand the genomic nature of PRSV,detection methods and the different advanced control methods.This review article will be helpful in developing the best management strategies for controlling PRSV. | Muhammad Umer Mustansar Mubeen Yasir Iftikhar Haider Ali Muhammad Zafar-ul-Hye Rafia Asghar Mazhar Abbas Malik Abdul Rehman Ernesto A.Moya-Elizondo Yuejun He | 2022 | Phyton-International Journal of Experimental Botany2022,91,10: | 1 |
