| 1 | Review on Zinc Oxide Nanoparticles: Antibacterial Activity and Toxicity Mechanism显示文摘Antibacterial activity of zinc oxide nanoparticles(Zn O-NPs) has received significant interest worldwide particularly by the implementation of nanotechnology to synthesize particles in the nanometer region. Many microorganisms exist in the range from hundreds of nanometers to tens of micrometers. Zn O-NPs exhibit attractive antibacterial properties due to increased specific surface area as the reduced particle size leading to enhanced particle surface reactivity. Zn O is a bio-safe material that possesses photo-oxidizing and photocatalysis impacts on chemical and biological species. This review covered Zn O-NPs antibacterial activity including testing methods, impact of UV illumination, Zn O particle properties(size, concentration, morphology, and defects), particle surface modification, and minimum inhibitory concentration. Particular emphasize was given to bactericidal and bacteriostatic mechanisms with focus on generation of reactive oxygen species(ROS) including hydrogen peroxide(H2O2), OH-(hydroxyl radicals), and O2-2(peroxide). ROS has been a major factor for several mechanisms including cell wall damage due to Zn O-localized interaction, enhanced membrane permeability, internalization of NPs due to loss of proton motive force and uptake of toxic dissolved zinc ions.These have led to mitochondria weakness, intracellular outflow, and release in gene expression of oxidative stress which caused eventual cell growth inhibition and cell death. In some cases, enhanced antibacterial activity can be attributed to surface defects on Zn O abrasive surface texture. One functional application of the Zn O antibacterial bioactivity was discussed in food packaging industry where Zn O-NPs are used as an antibacterial agent toward foodborne diseases. Proper incorporation of Zn O-NPs into packaging materials can cause interaction with foodborne pathogens, thereby releasing NPs onto food surface where they come in contact with bad bacteria and cause the bacterial death and/or inhibition. | Amna Sirelkhatim Shahrom Mahmud Azman Seeni Noor Haida Mohamad Kaus Ling Chuo Ann Siti Khadijah Mohd Bakhori Habsah Hasan Dasmawati Mohamad | 2015 | Nano-Micro Letters2015，7，3： | 76 |
| 2 | EXPERIMENTAL STUDY AND MODELING OF PRESSURE LOSS FOR FOAM-CUTTINGS MIXTURE FLOW IN HORIZONTAL PIPE显示文摘In this study,we first sought to elucidate foam rheology to describe foam flow behavior,and then to experimentally investigate the pressure losses for both foam and foam-cuttings flow in a horizontal pipe by considering both varied foam qualities of 80%, 85% and 90% and foam velocities.Also,a two-layer numerical model to predict pressure loss was developed based on experimental observations of cuttings behavior.Results show that the foam behaves like a power-law fluid.Furthermore,and the pressure loss significantly increases as foam velocity increases,while the delivered cuttings concentration dramatically decreases.Moreover,results indicate that both the pressure loss and the delivered cuttings concentration increase with foam quality.Comparisons between the experimental results and numerical model predictions show satisfactory agreement. | AMNA Gumati HIROSHI Takahshi | 2011 | Journal of Hydrodynamics2011，23，4： | 5 |
| 3 | 巴基斯坦视角下的中印关系显示文摘中印两国对外政策的变化导致两国超越了敌对关系而进入到经济合作关系,但还是不能超越合作伙伴关系而成为友好邻邦,中印友好关系受到一系列因素的限制。中巴友好得到四个支柱的支撑,但中国开始用全球利益的视角看待巴基斯坦。巴基斯坦和中国需要发展其他具有建设性的和具体的合作领域。 | Amna Yusaf Khokhar 杜佳宁 | 2011 | 南亚研究2011，，2： | 4 |
| 4 | Impact of direct acting antivirals on occurrence and recurrence of hepatocellular carcinoma: Biologically plausible or an epiphenomenon?显示文摘Hepatocellular carcinoma(HCC) is a major cause of morbidity and mortality worldwide. Chronic hepatitis C virus infection(HCV) is the most common cause of HCC in many European countries, Japan and Pakistan. Introduction of the new direct acting antivirals(DAAs) has revolutionized the management of HCV worldwide, with high rates of sustained virologic response in patients who could not have tolerated the previous interferon based treatments. However, recently there have been reports raising caution about the long term effects of DAAs, particularly a possible increased risk of HCC. Therefore this review explores the current molecular studies as well as clinical data that investigate the impact of DAAs on occurrence and recurrence of HCC. | Amna Subhan Butt Fatima Sharif Shahab Abid | 2018 | World Journal of Hepatology2018，10，2： | 4 |
| 5 | Stem taper functions for Betula platyphylla in the Daxing’an Mountains,northeast China显示文摘Accurate prediction of stem diameter is an important prerequisite of forest management.In this study,an appropriate stem taper function was developed for upper stem diameter estimation of white birch(Betula platyphylla Sukaczev)in ten sub-regions of the Daxing’an Mountains,northeast China.Three commonly used taper functions were assessed using a diameter and height dataset comprising 1344 trees.A first-order continuous-time error structure accounted for the inherent autocorrelation.The segmented model of Max and Burkhart(For Sci 22:283–289,1976.http://gffzzd3cc09b8251d45dfs0xn506c5w6pc66p0.ffgz.tsg.suse.edu.cn/10.1093/fores tscie nce/22.3.283)and the variable exponent taper function of Kozak(For Chron 80:507–515,2004.http://gffzzd3cc09b8251d45dfs0xn506c5w6pc66p0.ffgz.tsg.suse.edu.cn/10.5558/tfc80507-4)described the data accurately.Owing to its lower multicollinearity,the Max and Burkhart(1976)model is recommended for diameter estimation at specific heights along the stem for the ten sub-regions.After comparison,the Max and Burkhart(1976)model was refitted using nonlinear mixed-effects techniques.Mixed-effects models would be used only when additional upper stem diameter measurements are available for calibration.Differences in region-specific taper functions were indicated by the method of the non-linear extra sum of squares.Therefore,the particular taper function should be adjusted accordingly for each sub-region in the Daxing’an Mountains. | Muhammad Khurram Shahzad Amna Hussain Harold EBurkhart Fengri Li Lichun Jiang | 2021 | Journal of Forestry Research2021，32，2： | 4 |

| 10 | Walsh Hadamard Transform Based Transceiver Design for SC-FDMA with Discrete Wavelet Transform显示文摘This article proposes a new transceiver design for Single carrier frequency division multiple access(SCFDMA)system based on discrete wavelet transform(DWT). SCFDMA offers almost same structure as Orthogonal frequency division multiple access(OFDMA)with extra advantage of low Peak to Average Power Ratio(PAPR). Moreover,this article also suggests the application of Walsh Hadamard transform(WHT)for linear precoding(LP)to improve the PAPR performance of the system. Supremacy of the proposed transceiver over conventional Fast Fourier transform(FFT)based SCFDMA is shown through simulated results in terms of PAPR,spectral efficiency(SE)and bit error rate(BER). | Arsla Khan Amna Arif Tabassum Nawaz Sobia Baig | 2017 | China Communications2017，14，5： | 2 |
| 11 | In vivo laxative, anti-diarrheal, hepatoprotective and diuretic investigations of Sterculia diversifolia and its isolated compounds显示文摘OBJECTIVE:To investigated the laxative,anti-diarrheal,hepatoprotective and diuretic activity of Sterculia diversifolia and its isolated compounds.METHODS:The laxative activity was studied by counting wet stools while anti-diarrheal activity was performed by measuring gastrointestinal tract motility.Hepatoprotective activity was studied by biochemical and histo-pathological analysis while diuretic activity was performed by urine collection protocol.RESULTS:Doses of 30 and 100 mg/kg of crude methanolic extract of Sterculia diversifolia(MESD)stem bark and leaves,significantly(P<0.05,P<0.01)produced wet feces in subjects pretreated with atropine while 8-hydroxyquercetin and dihydroquercetin showed highly significant(P<0.001)results by increasing fecal weight and water contents without producing diarrhea.MESD stem bark and leaves also dose-dependently lowered diar-rhea while 8-hydroxyquercetin and dihydroquercetin showed highly significant(P<0.001)results by producing shaped stools in mice.MESD,8-hydroxyquercetin and dihydroquercetin offered significant protection against histopathological changes in the liver.Diuretic activity of Crude MESD stem bark and leaves extracts shows highly significant diuretic effect while dihydroquercetin showed better results than 8-hydroxyquercetin.CONCLUSION:It is concluded that Sterculia diversifolia and its isolated compounds bears laxative,anti-diarrheal,hepatoprotective and diuretic effects. | Fazle Rabbi Amir Zada Amna Nisar Muhammad Sohail Saifullah Khan Khalil Abid Ali Ahmad | 2021 | Journal of Traditional Chinese Medicine2021，41，5： | 2 |

| 19 | Early transmission dynamics of COVID-19 in a southern hemisphere setting:Lima-Peru:February 29^(th)-March 30^(th),2020显示文摘The COVID-19 pandemic that emerged in Wuhan China has generated substantial morbidity and mortality impact around the world during the last four months.The daily trend in reported cases has been rapidly rising in Latin America since March 2020 with the great majority of the cases reported in Brazil followed by Peru as of April 15th,2020.Although Peru implemented a range of social distancing measures soon after the confirmation of its first case on March 6th,2020,the daily number of new COVID-19 cases continues to accumulate in this country.We assessed the early COVID-19 transmission dynamics and the effect of social distancing interventions in Lima,Peru.We estimated the reproduction number,R,during the early transmission phase in Lima from the daily series of imported and autochthonous cases by the date of symptoms onset as of March 30th,2020.We also assessed the effect of social distancing interventions in Lima by generating short-term forecasts grounded on the early transmission dynamics before interventions were put in place.Prior to the implementation of the social distancing measures in Lima,the local incidence curve by the date of symptoms onset displays near exponential growth dynamics with the mean scaling of growth parameter,p,estimated at 0.96(95%CI:0.87,1.0)and the reproduction number at 2.3(95%CI:2.0,2.5).Our analysis indicates that school closures and other social distancing interventions have helped slow down the spread of the novel coronavirus,with the nearly exponential growth trend shifting to an approximately linear growth trend soon after the broad scale social distancing interventions were put in place by the government.While the interventions appear to have slowed the transmission rate in Lima,the number of new COVID-19 cases continue to accumulate,highlighting the need to strengthen social distancing and active case finding efforts to mitigate disease transmission in the region. | César V.Munayco Amna Tariq Richard Rothenberg Gabriela G.Soto-Cabezas Mary F.Reyes Andree Valle Leonardo Rojas-Mezarina César Cabezas Manuel Loayza Gerardo Chowell 无 | 2020 | Infectious Disease Modelling2020，5，1： | 1 |
