| 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 | Fast and interpretable classification of small X-ray diffraction datasets using data augmentation and deep neural networks显示文摘X-ray diffraction(XRD)data acquisition and analysis is among the most time-consuming steps in the development cycle of novel thin-film materials.We propose a machine learning-enabled approach to predict crystallographic dimensionality and space group from a limited number of thin-film XRD patterns.We overcome the scarce data problem intrinsic to novel materials development by coupling a supervised machine learning approach with a model-agnostic,physics-informed data augmentation strategy using simulated data from the Inorganic Crystal Structure Database(ICSD)and experimental data.As a test case,115 thin-film metalhalides spanning three dimensionalities and seven space groups are synthesized and classified.After testing various algorithms,we develop and implement an all convolutional neural network,with cross-validated accuracies for dimensionality and space group classification of 93 and 89%,respectively.We propose average class activation maps,computed from a global average pooling layer,to allow high model interpretability by human experimentalists,elucidating the root causes of misclassification.Finally,we systematically evaluate the maximum XRD pattern step size(data acquisition rate)before loss of predictive accuracy occurs,and determine it to be 0.16°2θ,which enables an XRD pattern to be obtained and classified in 5.5 min or less. | Felipe Oviedo Zekun Ren Shijing Sun Charles Settens Zhe Liu Noor Titan Putri Hartono Savitha Ramasamy Brian L.DeCost Siyu I.P.Tian Giuseppe Romano Aaron Gilad Kusne Tonio Buonassisi | 2019 | npj Computational Materials2019，，1： | 15 |

| 4 | 铝-铜搅拌摩擦焊综述(英文)显示文摘在工程应用中需要通过连接不同的材料制成零部件以满足不同的要求。由于所用材料的力学、热和电性能存在巨大差异,使得这些零部件的制造极具挑战性。搅拌摩擦焊(FSW)能够用于连接异种材料,如铝(Al)和铜(Cu)。关于异种材料的连接,特别是铝-铜,文献来源比较分散,因此,铝-铜搅拌摩擦焊的信息收集比较繁琐。本文综述铝-铜的搅拌摩擦焊,为科研人员提供相关信息。文中全面涵盖和系统总结铝-铜搅拌摩擦焊的各项问题,如工具设计和尺寸、工艺参数以及流程对零件力学性能、微观组织和缺陷形成的影响。此外,还提出和探讨铝-铜搅拌摩擦焊的几个改进工艺。该工作不仅列举前人的主要成果,还提出铝-铜搅拌摩擦焊的发展建议。 | Nidhi SHARMA Zahid A.KHAN Arshad Noor SIDDIQUEE | 2017 | Transactions of Nonferrous Metals Society of China2017，27，10： | 11 |
| 5 | Negative reflection and negative surface wave conversion from obliquely incident electromagnetic waves显示文摘Complete control of spatially propagating waves(PWs)and surface waves(SWs)is an ultimate goal that scientists and engineers seek for,in which negative reflection of PW and negative surface wave are two exotic phenomena.Here,we experimentally demonstrate an anisotropic digital coding metasurface capable of controlling both PWs and SWs with a single coding pattern.On the basis of the digital description of coding metasurfaces,a simple coding method is proposed to allow dual functionalities(either PW or SW manipulations)under two orthogonal polarizations at arbitrarily oblique incidences,thus improving the adaptability of digital coding metasurfaces in more practical circumstances.With elaborately designed ellipse-shaped coding particles,we experimentally demonstrate various functions under oblique incidences,including the negative reflection of PW,negative SW,anomalous reflection and their arbitrary combinations,all having good agreements with theoretical and numerical predictions.We believe that the proposed method may enable the digital coding metasurfaces to have broad applications in radar detections,wireless communications and imaging. | Shuo Liu Tie Jun Cui Ahsan Noor Zui Tao Hao Chi Zhang Guo Dong Bai Yan Yang Xiao Yang Zhou | 2018 | Light(Science & Applications)2018，7，1： | 10 |
| 6 | Correlation of transient elastography with hepatic venous pressure gradient in patients with cirrhotic portal hypertension: A study of 326 patients from India显示文摘AIM To study the diagnostic accuracy of transient elastography(TE) for detecting clinically significant portal hypertension(CSPH) in Indian patients with cirrhotic portal hypertension.METHODS This retrospective study was conducted at the Institute of Liver, Gastroenterology, and Panceatico-Biliary Sciences, Sir Ganga Ram Hospital, New Delhi, on consecutive patients with cirrhosis greater than 15 years of age who underwent hepatic venous pressure gradient(HVPG) and TE from July 2011 to May 2016. Correlation between HVPG and TE was analyzed using the Spearman's correlation test. Receiver operating characteristic ( ROC) curves were prepared for determining the utility of TE in predicting various stages of portal hypertension. The best cut-off value of TE forthe diagnosis of CSPH was obtained using the Youden index.RESULTS The study included 326 patients [median age 52(range 16-90) years; 81% males]. The most common etiology of cirrhosis was cryptogenic(45%) followed by alcohol(34%). The median HVPG was 16.0(range 1.5 to 30.5) mm Hg. Eighty-five percent of patients had CSPH. A significant positive correlation was noted between TE and HVPG(rho 0.361, P < 0.001). The area under ROC curve for TE in predicting CSPH was 0.740(95%CI: 0.662-0.818)(P < 0.01). A cut-off value of TE of 21.6 k Pa best predicted CSPH with a positive predictive value(PPV) of 93%.CONCLUSION TE has a fair positive correlation with HVPG; thus, TE can be used as a non-invasive modality to assess the degree of portal hypertension. A cut-off TE value of 21.6 k Pa identifies CSPH with a PPV of 93%. | Ashish Kumar Noor Muhammad Khan Shrihari Anil Anikhindi Praveen Sharma Naresh Bansal Vikas Singla Anil Arora | 2017 | World Journal of Gastroenterology2017，23，4： | 8 |

| 9 | Structural, morphological, Raman, optical, magnetic, and antibacterial characteristics of CeO2 nanostructures显示文摘In this study, CeO_2 nanostructures were synthesized by a soft chemical method. A hydrothermal treatment was observed to lead to an interesting morphological transformation of the nanoparticles into homogeneous microspheres composed of nanosheets with an average thickness of 40 nm. Structural analysis revealed the formation of a single-phase cubic fluorite structure of CeO_2 for both samples. A Raman spectroscopic study confirmed the XRD results and furthermore indicated the presence of a large number of oxygen vacancies in the nanosheets. These oxygen vacancies led to room-temperature ferromagnetism(RTFM) of the CeO_2 nanosheets with enhanced magnetic characteristics. Amazingly, the nanosheets exhibited substantially greater antibacterial activity than the nanoparticles. This greater antibacterial activity was attributed to greater exposure of high-surface-energy polar surfaces and to the presence of oxygen vacancies. | Fazal Abbas Javed Iqbal Tariq Jan Noor Badshah Qaisar Mansoor Muhammad Ismail | 2016 | International Journal of Minerals,Metallurgy and Materials2016，23，1： | 6 |
| 10 | Characteristics and advantages of adeno-associated virus vector-mediated gene therapy for neurodegenerative diseases显示文摘Common neurodegenerative diseases of the central nervous system are characterized by progressive damage to the function of neurons, even leading to the permanent loss of function. Gene therapy via gene replacement or gene correction provides the potential for transformative therapies to delay or possibly stop further progression of the neurodegenerative disease in affected patients. Adeno-associated virus has been the vector of choice in recent clinical trials of therapies for neurodegenerative diseases due to its safety and efficiency in mediating gene transfer to the central nervous system. This review aims to discuss and summarize the progress and clinical applications of adeno-associated virus in neurodegenerative disease in central nervous system. Results from some clinical trials and successful cases of central neurodegenerative diseases deserve further study and exploration. | Yuan Qu Yi Liu Ahmed Fayyaz Noor Johnathan Tran Rui Li | 2019 | Neural Regeneration Research2019，14，6： | 6 |
| 11 | Clinical relevance of endoscopic assessment of inflammation in ulcerative colitis: Can endoscopic evaluation predict outcomes?显示文摘Ulcerative colitis(UC) is a chronic inflammatory bowel condition characterised by a relapsing and remitting course. Symptom control has been the traditional mainstay of medical treatment. It is well known that histological inflammatory activity persists despite adequate symptom control and absence of endoscopic inflammation. Current evidence suggests that presence of histological inflammation poses a greater risk of disease relapse and subsequent colorectal cancer risk. New endoscopic technologies hold promise for developing endoscopic markers of mucosal inflammation. Achieving endoscopic and histological remission appears be the future aim of medical treatments for UC. This review article aims to evaluate the use of endoscopy as a tool in assessment of mucosal inflammation UC and its correlation with disease outcomes. | Noor Mohammed Venkataraman Subramanian | 2016 | World Journal of Gastroenterology2016，22，42： | 6 |

| 18 | Cancer models in preclinical research:A chronicle review of advancement in effective cancer research显示文摘Cancer is a major stress for public well-being and is the most dreadful disease.The models used in the discovery of cancer treatment are continuously changing and extending toward advanced preclinical studies.Cancer models are either naturally existing or artificially prepared experimental systems that show similar features with human tumors though the heterogeneous nature of the tumor is very familiar.The choice of the most fitting model to best reflect the given tumor system is one of the real difficulties for cancer examination.Therefore,vast studies have been conducted on the cancer models for developing a better understanding of cancer invasion,progression,and early detection.These models give an insight into cancer etiology,molecular basis,host tumor interaction,the role of microenvironment,and tumor heterogeneity in tumor metastasis.These models are also used to predict novel can-cer markers,targeted therapies,and are extremely helpful in drug development.In this review,the potential of cancer models to be used as a platform for drug screening and therapeutic discoveries are highlighted.Although none of the cancer models is regarded as ideal because each is associated with essential caveats that restraint its application yet by bridging the gap between preliminary cancer research and transla-tional medicine.However,they promise a brighter future for cancer treatment. | Humna Sajjad Saiqa Imtiaz Tayyaba Noor Yusra Hasan Siddiqui Anila Sajjad Muhammad Zia | 2021 | Animal Models and Experimental Medicine2021，4，2： | 5 |
| 19 | Pancreatitis and pancreatic cancer:A case of the chicken or the egg显示文摘Acute pancreatitis(AP),chronic pancreatitis(CP)and pancreatic cancer are three distinct pancreatic diseases with different prognoses and treatment options.However,it may be difficult to differentiate between benign and malignant disease.AP may be a first symptom of pancreatic cancer,particularly in patients between the ages of 56 and 75 with presumed idiopathic AP who had a concomitant diagnosis of new-onset diabetes mellitus or patients who present with CP at diagnosis of AP.In these patients,additional imaging is warranted,preferably by endoscopic ultrasonography.CP may lead to pancreatic cancer through oncogenic mutations,mostly in patients with hereditary CP,and in patients in whom risk factors for pancreatic cancer(e.g.,nicotine and alcohol abuse)are also present.Patients with PRSS1-mediated CP and patients with a history of autosomal dominant hereditary CP without known genetic mutations may be considered for surveillance for pancreatic cancer.Pancreatic inflammation may mimic pancreatic cancer by appearing as a focal mass-forming lesion on imaging.Differentiation between the above mentioned benign and malignant disease may be facilitated by specific features like the duct-penetrating sign and the duct-to-parenchyma ratio.Research efforts are aimed towards developing a superior discriminant between pancreatitis and pancreatic cancer in the form of imaging modalities or biomarkers.This may aid clinicians in timely diagnosing pancreatic cancer in a potentially curable stage. | Devica S Umans Sanne A Hoogenboom Noor J Sissingh Selma J Lekkerkerker Robert C Verdonk Jeanin E van Hooft | 2021 | World Journal of Gastroenterology2021，27，23： | 5 |
| 20 | 搅拌摩擦焊清洁制造工艺过程中的缺陷分析(英文)显示文摘清洁生产是制造工艺过程中追求的目标。搅拌摩擦焊是一种比目前最好的传统焊接工艺更好、对环境损害更低的连接技术。搅拌摩擦焊工艺的能量效率高、无耗材、无损耗、无辐射。因此,它是一种能获得优质焊接接头的清洁焊接工艺。但它在焊接过程中会产生缺陷,为使其成为一种可靠的生产工艺,需要对其进行进一步优化。本文作者对搅拌摩擦焊接头的缺陷进行表征。结果表明,缺陷的产生是由于焊件过程的产生的热量不够、搅拌针附近的物质移动不充分、搅拌针后部的材料致密化不够。焊接过程中产生的热量和物料的搅拌程度取决于搅拌摩擦焊的焊接参数。焊接参数选择不当,可导致缺陷的产生。本文所得结果来源于文献和实验。根据各种缺陷的特征,如其可能产生的位置、减少缺陷产生的主要参数等,提出了减少缺陷产生的一些措施。 | Noor Zaman KHAN Zahid A.KHAN Arshad Noor SIDDIQUEE Abdulrahman M.AL-AHMARI Mustufa H.ABIDI | 2017 | Transactions of Nonferrous Metals Society of China2017，27，7： | 4 |
