| 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 |

| 3 | Normal vitamin D levels are associated with spontaneous hepatitis B surface antigen seroclearance显示文摘AIM: To investigate a possible association between serum vitamin D levels and spontaneous hepatitis B surface antigen (HBsAg) seroclearance. METHODS: Fifty-three patients diagnosed with chronic inactive hepatitis B and spontaneous HBsAg seroclearance were followed up in two Israeli liver units between 2007 and 2012. This retrospective study reviewed medical charts of all the patients, extracting demographic, serological and vitamin D rates in the serum, as well as medical conditions and current medical therapy. Spontaneous HBsAg seroclearance was defined as the loss of serum HBsAg indefinitely. Vitamin D levels were compared to all patients who underwent spontaneousHBsAg seroclearance.HBsAg seroclearance. RESULTS: Out of the 53 patients who underwent hepatitis B antigen seroclearance, 44 patients (83%) had normal levels of 25-hydroxyvitamin vitamin D compared to 9 patients (17%) who had below normal levels. Multivariate analysis showed that age (>35 years) OR = 1.7 (95%CI: 1.25-2.8, P=0.05), serum vitamin D levels (>20 ng/mL) OR = 2.6 (95%CI: 2.4-3.2, P=0.02), hepatitis B e antigen negativity OR = 2.1 (95%CI: 2.2-3.1, P=0.02), low viral load (hepatitis B virus DNA < 100 IU/mL) OR = 3 (95%CI: 2.6-4.2, P = 0.01) and duration of HBsAg seropositivity (> 8 years) OR = 1.6 (95%CI: 1.15-2.6, P=0.04) were also associated with spontaneous HBsAg seroclearance. CONCLUSION: We found a strong correlation between normal vitamin D levels and spontaneous HBsAg seroclearance. | Mahmud Mahamid William Nseir Omar Abu Elhija Shimon Shteingart Ammad Mahamid Mosab Smamra Benjamin Koslowsky | 2013 | World Journal of Hepatology2013，5，6： | 14 |

| 5 | Antioxidant Defense Mechanisms of Salinity Tolerance in Rice Genotypes显示文摘In order to elucidate the role of antioxidant responses in salinity tolerance in rice genotypes under salt stress, experiments were conducted using four rice varieties, including salt-sensitive BRRI dhan 28 and three salt-tolerant varieties BRRI dhan 47, BINA dhan 8 and BINA dhan 10. Thirty-day-old rice seedlings were transplanted into pots. At the active tillering stage(35 d after transplanting), plants were exposed to different salinity levels(0, 20, 40 and 60 mmol/L NaCl). Salt stress caused a significant reduction in growth for all the rice genotypes. Growth reduction was higher in the salt-sensitive genotype than in the salt-tolerant ones, and BINA dhan 10 showed higher salt tolerance in all measured physiological parameters. The reduction in shoot and root biomass was found to be minimal in BINA dhan 10. Chlorophyll content significantly decreased under salt stress except for BINA dhan 10. Proline content significantly increased in salt-tolerant rice genotypes with increased salt concentration, and the highest proline content was obtained from BINA dhan 10 under salt stress. Catalase and ascorbate peroxidase activities significantly decreased in salt-sensitive genotype whereas significantly increased in salt-tolerant ones with increasing salt concentration. However, salt stress significantly decreased guaiacol peroxidase activity in all the rice genotypes irrespective of salt tolerance. K^+/Na^+ ratio also significantly decreased in shoots and roots of all the rice genotypes. The salt-tolerant genotype BINA dhan 10 maintained higher levels of chlorophyll and proline contents as well as catalase and ascorbate peroxidase activities under salt stress, thus, this might be the underlying mechanism for salt tolerance. | Mohammad Golam KIBRIA Mahmud HOSSAIN Yoshiyuki MURATA Md.Anamul HOQUE | 2017 | Rice science2017，24，3： | 10 |
| 6 | The research and development on the antioxidants in prevention of diabetic complications显示文摘Diabetes mellitus can damage the eyes,kidneys,nerves and heart.Microvascular and macrovascular disorders are the leading causes of morbidity and mortality in diabetic patients.Hyperglycemia can increase the indicators of lipid peroxidation and oxidative stress in which free radicals have the main role in the pathogenesis of these complications.Therefore,antioxidants which combat oxidative stress should be able to prevent and repair free radicals induced damages.Although free radicals contribute to kidney damage,atherosclerosis,diabetes,heart disease,nephrotoxicity and hepatotoxicity; however,clinical trials do not uniquely confirm a substantial impact on diabetic damage.It seems that antioxidants in vegetables,fruits and grains help preventing diabetes complications; however,there is little evidence that taking single antioxidants such as vitamin E or vitamin C protect these complications.The findings about combination antioxidants are also complicated and not entirely clear.In this review paper we tried to present the role of oxidative stress on microvascular complications of type2 diabetes mellitus.Other objective of this paper is to review the new findings about the role of various antioxidants on prevention and treatment of diabetes mellitus as well as its complications including retinopathy,nephropathy and neuropathy. | Mohammad Rahimi-Madiseh Afsaneh Malekpour-Tehrani Mahmoud Bahmani Mahmud Rafieian-kopaei | 2016 | Asian Pacific Journal of Tropical Medicine2016，9，9： | 9 |

| 9 | Survival analysis of cholangiocarcinoma:A 10-year experience in Malaysia显示文摘AIM:To investigate the clinical features and survival of patients treated for cholangiocarcinoma in our institution and to analyze the factors affecting their survival.METHODS:This retrospective cohort study assessed patients diagnosed with cholangiocarcinoma between January 1997 and December 2007 at the University Malaya Medical Centre in Malaysia.The clinical data and associated outcomes were collected using a structured proforma.RESULTS:Of the 69 patients diagnosed with cholangiocarcinoma,38 (55%) were male;mean patient age was 61 years.Twelve patients (17%) had intrahepatic,38 (55%) had perihilar and 19 (28%) had distal tumors.Only 12 patients underwent curative surgery,including seven R0 resections.Only one patient died within 30 d after surgery.The overall median survival was 4 mo,whereas the median survival of R0 resected patients was 16 mo.The overall 1-,2-and 3-year cumulative survival rates were 67%,17% and 17%,respectively.Survival rates were significantly associated with curative resection (P=0.002),intrahepatic tumor (P=0.003),negative margin status (P=0.013),early tumor stage (P=0.016),higher tumor differentiation (P=0.032) and absence of jaundice (P=0.038).Multivariate analysis showed that tumor location was a significant independent predictor of patient survival.CONCLUSION:Curative,margin-negative resection of early stage,well-differentiated intrahepatic tumors is associated with improved patient survival. | Ahmad Ramzi Yusoff Mohd Muzammil Abdul Razak Yoong Boon Koon R Vijeyasingam Siti Zuraidah Mahmud | 2012 | World Journal of Gastroenterology2012，18，5： | 7 |
| 10 | ABCD^(2) risk score does not predict the presence of cerebral microemboli in patients with hyper-acute symptomatic critical carotid artery stenosis显示文摘Introduction:ABCD^(2) risk score and cerebral microemboli detected by transcranial Doppler(TCD)have been separately shown to the predict risk of recurrent acute stroke.We studied whether ABCD2 risk score predicts cerebral microemboli in patients with hyper-acute symptomatic carotid artery stenosis.Participants and methods:We studied 206 patients presenting within 2 weeks of transient ischaemic attack or minor stroke and found to have critical carotid artery stenosis(≥50% ).86 patients(age 70±1(SEM:years),58 men,83 Caucasian)had evidence of microemboli;72(84% )of these underwent carotid endarterectomy(CEA).120 patients(age 72±1 years,91 men,113 Caucasian)did not have microemboli detected;102(85% )of these underwent CEA.Data were analysed using X2 and Mann–Whitney U tests and receiver operating characteristic(ROC)curves.Results:140/206(68% :95% CI 61.63 to 74.37)patients with hyper-acute symptomatic critical carotid stenosis had an ABCD2 risk score≥4.There was no significant difference in the NICE red flag criterion for early assessment(ABCD^(2) risk score≥4)for patients with cerebral microemboli versus those without microemboli(59/86 vs 81/120 patients:OR 1.05 ABCD2 risk score≥4(95% CI 0.58 to 1.90,p=0.867)).The ABCD2 risk score was<4 in 27 of 86(31% :95% CI 21 to 41)embolising patients and in 39 of 120(31% :95% CI 23 to 39)without cerebral microemboli.After adjusting for pre-neurological event antiplatelet treatment(APT),area under the curve(AUC)of ROC for ABCD2 risk score showed no prediction of cerebral microemboli(no pre-event APT,n=57:AUC 0.45(95% CI 0.29 to 0.60,p=0.531);preevent APT,n=147:AUC 0.51(95% CI 0.42 to 0.60,p=0.804)).Conclusions:The ABCD2 score did not predict the presence of cerebral microemboli or carotid disease in over one-quarter of patients with symptomatic critical carotid artery stenosis.On the basis of NICE guidelines(refer early if ABCD2≥4),assessment of high stroke risk based on ABCD2 scoring may lead to inappropriate delay in urgent treatment in many patients. | Mahmud Saedon Charles E Hutchinson Christopher H E Imray Donald R J Singer | 2017 | Stroke & Vascular Neurology2017，2，2： | 6 |

| 12 | Predicting common bile duct stones by non-invasive parameters显示文摘Background:Common bile duct(CBD)stone affect about 10%of patients with symptomatic cholelithiasis.The American Society for Gastrointestinal Endoscopy(ASGE)published a strategy in 2010 for managing patients with suspected choledocholithiasis.This study aimed to assess the performance of different clinical parameters in predicting CBD stones.Methods:A total of 344 patients suspected to suffer from CBD stone and referred to endoscopic ultrasound(EUS)were included.Parameters were collected and their prediction power for CBD stones was assessed.Results:One hundred and sixty-seven patients without CBD stone according to EUS(group A)were compared to 177 patients with CBD stones(group B).Several predictive factors for CBD stone were identified on univariate analysis.In multivariate regression analysis,CBD width by US(OR=1.224,95%CI:1.073–1.359;P=0.0026),age(OR=1.023,95%CI:1.011–1.035;P=0.0002)and gamma glutamyl transferase(GGT)level(OR=1.001,95%CI:1.000–1.002;P=0.0018)were significantly correlated with CBD stone,with receiver operator characteristics(ROC)of 0.7259.We generated a diagnostic equation[age(yr)×0.1+CBD width(mm)by US×1+GGT(U/L)×0.005]to predict CBD stone with ROC of 0.7287.Conclusions:We suggest this score as a very strong predictor for CBD stones,and to reduce the strength of total bilirubin and transaminases as predictors. | Anas Kadah Tawfik Khoury Mahmud Mahamid Nimer Assy Wisam Sbeit | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，3： | 4 |
| 13 | Rapid Detection of Wheat Blast Pathogen Magnaporthe oryzae Triticum Pathotype Using Genome-Specific Primers and Cas12a-mediated Technology显示文摘Wheat blast,caused by the fungus Magnaporthe oryzae Triticum(MoT)pathotype,is a devastating disease persistent in South America and Bangladesh.Since MoT generally fails to cause visual symptoms in wheat until the heading stage when the infection would have advanced,disease control by fungicide application solely based on the detection of visual symptoms is ineffective.To develop an accurate and sensitive method to detect MoT at the seedling and vegetative stages for disease control,we sequenced the genomes of two MoT isolates from Brazil and identified two DNA fragments,MoT-6098 and MoT-6099,that are present in the MoT genome but not in the genome of the rice-infecting Magnaporthe oryzae Oryzae(MoO)pathotype.Using polymerase chain reaction(PCR),we confirmed the specificity of the two markers in 53 MoT and MoO isolates from South America and Bangladesh.To test the efficiency of the two markers,we first established a loop-mediated isothermal amplification(LAMP)method to detect MoT at isothermal conditions,without the use of a PCR machine.Following this,we used the Cas12a protein and guide RNAs(gRNAs)to target the MoT-6098 and MoT-6099 sequences.The activated Cas12a showed indiscriminate single-stranded deoxyribonuclease(ssDNase)activity.We then combined targetdependent Cas12a ssDNase activation with recombinase polymerase amplification(RPA)and nucleic acid lateral flow immunoassay(NALFIA)to develop a method that accurately,sensitively,and cost-effectively detects MoT-specific DNA sequences in infected wheat plants.This novel technique can be easily adapted for the rapid detection of wheat blast and other important plant diseases in the field. | Houxiang Kang Ye Peng Kangyu Hua Yufei Deng Maria Bellizzi Dipali Rani Gupta Nur Uddin Mahmud Alfredo S.Urashima Sanjoy Kumar Paul Gary Peterson Yilin Zhou Xueping Zhou Md Tofazzal Islam Guo-Liang Wang | 2021 | Engineering2021，7，9： | 4 |

| 17 | Gut microbiome profiling and colorectal cancer in African Americans and Caucasian Americans显示文摘AIM To determine whether and to what extent the gut microbiome is involved in regulating racial disparity in colorectal cancer(CRC). METHODS All patients were recruited and experiments were performed in accordance with the relevant guidelines and regulations by the Institutional Review Boards (IRB), committees of the John D. Dingell VAMC and Wayne State University guidelines. African American (AA) and Caucasian American (CA) patients were scheduled for an outpatient screening for colonoscopy, and no active malignancy volunteer patients were doubly consented, initially by the gastroenterologist and later by the study coordinator, for participation in the study. The gut microbial communities in colonic effluents from AAs and CAs were examined using 16 sRNA profiling, and bacterial identifications were validated by performing SYBR-based Real Time PCR. For metagenomic analysis to characterize the microbial communities, multiple software/tools were used, including Metastats and R statistical software.RESULTS It is generally accepted that the incidence and mortality of CRC is higher in AAs than in CAs. However, the reason for this disparity is not well understood. We hypothesize that the gut microbiome plays a role in regulating this disparity. Indeed, we found significant differences in species richness and diversity between AAs and CAs. Bacteroidetes was more abundant in AAs than in CAs. In particular, the pro-inflammatory bacteria Fusobacterium nucleatum and Enterobacter species were significantly higher in AAs, whereas probiotic Akkermansia muciniphila and Bifidobacterium were higher in CAs. The polyphyletic Clostridia class showed a divergent pattern, with Clostridium XI elevated in AAs, and Clostridium IV, known for its beneficial function, higher in CAs. Lastly, the AA group had decreased microbial diversity overall in comparison to the CA group. In summary, there were significant differences in pro-inflammatory bacteria and microbial diversity between AA and CA, which may help explain the CRC disparity between groups.CONCLUSION Our current investigation, for the first time, demonstrates microbial dysbiosis between AAs and CAs, which could contribute to the racial disparity of CRC. | Lulu Farhana Fadi Antaki Farhan Murshed Hamidah Mahmud Stephanie L Judd Pratima Nangia-Makker Edi Levi Yingjie Yu Adhip PN Majumdar | 2018 | World Journal of Gastrointestinal Pathophysiology2018，9，2： | 3 |
| 18 | Properties and Applications of Bamboo Fiber—A Current-State-of-the Art显示文摘Fibers are used in many forms in engineering applications–one of the most common being used as reinforcement.Due to its renewable short natural growth cycle and abundance of bamboo resources,bamboo fiber has attracted attention over other natural fibers.Bamboo fiber has a complex natural structure but offers excellent mechanical properties,which are utilized in the textile,papermaking,construction,and composites industry.However,bam-boo fibers can easily absorb moisture and are prone to corrosion limiting their use in engineering applications.Therefore,a better understanding of bamboo fiber is particularly important.This paper reviews all existing research on the mechanical characterization of bamboo fiber with an emphasis on the extraction and treatment techniques,and their effect on relevant properties.The chemical composition of bamboo fibers has also been thoroughly investigated and presented herein.Current applications and future opportunities for bamboo fibers in various fields have been presented with a focus on research needs.This work can serve as a reference for future research on bamboo fiber. | Chen Chen Haitao Li Assima Dauletbek Feng Shen David Hui Milan Gaff Rodolfo Lorenzo Ileana Corbi Ottavia Corbi Mahmud Ashraf | 2022 | Journal of Renewable Materials2022，10，3： | 3 |

| 20 | Flooding and its relationship with land cover change, population growth, and road density显示文摘Bangladesh experiences frequent hydro-climatic disasters such as flooding.These disasters are believed to be associated with land use changes and climate variability.However,identifying the factors that lead to flooding is challenging.This study mapped flood susceptibility in the northeast region of Bangladesh using Bayesian regularization back propagation(BRBP)neural network,classification and regression trees(CART),a statistical model(STM)using the evidence belief function(EBF),and their ensemble models(EMs)for three time periods(2000,2014,and 2017).The accuracy of machine learning algorithms(MLAs),STM,and EMs were assessed by considering the area under the curve—receiver operating characteristic(AUC-ROC).Evaluation of the accuracy levels of the aforementioned algorithms revealed that EM4(BRBP-CART-EBF)outperformed(AUC>90%)standalone and other ensemble models for the three time periods analyzed.Furthermore,this study investigated the relationships among land cover change(LCC),population growth(PG),road density(RD),and relative change of flooding(RCF)areas for the period between 2000 and 2017.The results showed that areas with very high susceptibility to flooding increased by 19.72%between 2000 and 2017,while the PG rate increased by 51.68%over the same period.The Pearson correlation coefficient for RCF and RD was calculated to be 0.496.These findings highlight the significant association between floods and causative factors.The study findings could be valuable to policymakers and resource managers as they can lead to improvements in flood management and reduction in flood damage and risks. | Mahfuzur Rahman Chen Ningsheng Golam Iftekhar Mahmud Md Monirul Islam Hamid Reza Pourghasemi Hilal Ahmad Jules Maurice Habumugisha Rana Muhammad Ali Washakh Mehtab Alam Enlong Liu Zheng Han Huayong Ni Tian Shufeng Ashraf Dewan | 2021 | Geoscience Frontiers2021，12，6： | 3 |
