| 1 | Airborne bioaerosols and their impact on human health显示文摘Bioaerosols consist of aerosols originated biologically such as metabolites, toxins, or fragments of microorganisms that are present ubiquitously in the environment. International interests in bioaerosols have increased rapidly to broaden the pool of knowledge on their identification,quantification, distribution, and health impacts(e.g., infectious and respiratory diseases,allergies, and cancer). However, risk assessment of bioaerosols based on conventional culture methods has been hampered further by several factors such as:(1) the complexity of microorganisms or derivatives to be investigated;(2) the purpose, techniques, and locations of sampling; and(3) the lack of valid quantitative criteria(e.g., exposure standards and dose/effect relationships). Although exposure to some microbes is considered to be beneficial for health,more research is needed to properly assess their potential health hazards including inter-individual susceptibility, interactions with non-biological agents, and many proven/unproven health effects(e.g., atopy and atopic diseases). | Ki-Hyun Kim Ehsanul Kabir Shamin Ara Jahan | 2018 | Journal of Environmental Sciences2018，30，5： | 22 |
| 2 | Impact of Nitrogen, Phosphorus and Potassium on Brown Planthopper and Tolerance of Its Host Rice Plants显示文摘The brown planthopper(BPH),Nilaparvata lugens(St?l),appeared as a devastating pest of rice in Asia. Experiments were conducted to study the effects of three nutrients,nitrogen(N),phosphorus(P) and potassium(K),on BPH and its host rice plants. Biochemical constituents of BPH and rice plants with varying nutrient levels at different growth stages,and changes in relative water content(RWC) of rice plants were determined in the laboratory. Feeding of BPH and the tolerance of rice plants to BPH with different nutrient levels were determined in the nethouse. Concentrations of N and P were found much higher in the BPH body than in its host rice plants,and this elemental mismatch is an inherent constraint on meeting nutritional requirements of BPH. Nitrogen was found as a more limiting element for BPH than other nutrients in rice plants. Application of N fertilizers to the rice plants increased the N concentrations both in rice plants and BPH while application of P and K fertilizers increased their concentrations in plant tissues only but not in BPH. Nitrogen application also increased the level of soluble proteins and decreased silicon content in rice plants,which resulted in increased feeding of BPH with sharp reduction of RWC in rice plants ultimately caused susceptible to the pest. P fertilization increased the concentration of P in rice plant tissues but not changed N,K,Si,free sugar and soluble protein contents,which indicated little importance of P to the feeding of BPH and tolerance of plant against BPH. K fertilization increased K content but reduced N,Si,free sugar and soluble protein contents in the plant tissues which resulted in the minimum reduction of RWC in rice plants after BPH feeding,thereby contributed to higher tolerance of rice plants to brown planthopper. | Md Mamunur RASHID Mahbuba JAHAN Khandakar Shariful ISLAM | 2016 | Rice science2016，23，3： | 12 |

| 5 | Sensitive Voltammetric Determination of Captopril Using a Carbon Paste Electrode Modified with Nano-TiO_2/Ferrocene Carboxylic Acid显示文摘A carbon paste electrode (CPE) modified with ferrocene carboxylic acid (FcCA) and TiO2 nanoparticles was constructed by incorporating TiO2 nanoparticles and ferrocene carboxylic acid into the carbon paste matrix. The electrochemical behavior of captopril (CAP) at the surface of the modified electrode was investigated using electroanalytical methods. The modified electrode showed excellent electrocatalytic activity for the oxidation of CAP in aqueous solutions at physiological pH values. Cyclic voltammetric curves showed that the oxidation of CAP at the surface of the modified electrode reduced its overpotential by more than 290 mV. The modified electrode was used for detecting captopril using cyclic voltammetry and square wave voltammetry techniques. A calibration curve in the range of 0.03 to 2400 μmol/L was obtained that had a detection limit of 0.0096 μmol/L (3?) under the optimized conditions. The modified electrode was successfully used for the determination of captopril in pharmaceutical and biological samples. | Jahan Bakhsh RAOOF Reza OJANI Mehdi BAGHAYERI | 2011 | 催化学报2011，32，11： | 6 |
| 6 | Correlation between KCNQ1 and KCNJ11 gene polymorphisms and type 2 and posttransplant diabetes mellitus in the Asian Indian population显示文摘Type 2 diabetes mellitus(T2DM)and post-transplant diabetes mellitus(PTDM)share a common pathophysiology.However,diabetes mellitus is a complex disease,and T2DM and PTDM have different etiologies.T2DM is a metabolic disorder,characterized by persistent hyperglycemia,whereas PTDM is a condition of abnormal glucose tolerance,with variable onset after organ transplant.The KCNQ1 and KCNJ11 gene encode potassium channels,which mediate insulin secretion from pancreatic b-cells,and KCN gene mutations are correlated with the development of diabetes.However,no studies have been carried out to establish an association between KCNQ1 and KCNJ11 gene polymorphisms and T2DM and PTDM.Therefore,our study was aimed at the identification of the role of KCNQ1 and KCNJ11 gene polymorphisms associated with T2DM and the risk of developing PTDM in the Asian Indian population.We have carried out a caseecontrol study including 250 patients with T2DM,250 control subjects,42 patients with PTDM and 98 subjects with non-PTDM.PCR-RFLP analysis was carried out following the isolation of genomic DNA from EDTA-blood samples.The results of the present study reveal that two single nucleotide polymorphisms(rs2283228 and rs5210,of the KCNQ1 and KCNJ11 genes,respectively)are associated with both T2DM and PTDM.The results of our study suggest a role of KCNQ1 and KCNJ11 gene variants in the increased risk of T2DM and PTDM in the Asian Indian population. | Imran Ali Khan Kiran Kumar Vattam Parveen Jahan Kamal Kiran Mukkavali Qurratulain Hasan Pragna Rao | 2015 | Genes & Diseases2015，2，3： | 6 |
| 7 | 利用图像和机器学习检测大豆作物幼苗期玉米杂苗显示文摘在大豆-玉米轮作生产过程中,玉米杂苗会与大豆苗竞争水和肥料,而且很容易遮住大豆苗,影响害虫(如玉米根虫)的防控,降低大豆品质。因此,在大豆幼苗期及时检测出玉米杂苗并对其进行处理非常重要。传统的人工检测方法主观性强、效率低,传感器和算法的发展为自动检测玉米杂苗提供了更好的解决方案。本研究在温室环境下模仿田间条件,待玉米和大豆发芽后,连续5天用因特尔RealSense D435相机采集彩色图像,并人工裁剪幼苗图像区域,在此基础上对图像进行分割和去噪。在采集图像形状、色彩和纹理特征值后,对所采集的特征值进行权重分析,保留前10种重要的特征值导入基于特征的机器学习算法中进行模型训练和预测。预测结果表明,支持向量机模型(SVM)、神经网络(NN)和随机森林(RF)的预测精度分别为85.3%,81.5%和82.6%。将数据集导入GoogLeNet和VGG-16两种深度学习模型进行训练,预测精度分别为96.0%和96.2%。VGG-16模型在区分大豆幼苗和玉米杂苗中有较好的表现,彩色图像和VGG-16模型组成的系统可以自动检测大豆生长过程中玉米杂苗的情况,为农民提供准确的信息,帮助其进行生产决策和田间管理。 | Paulo FLORES 张昭 Jithin MATHEW Nusrat JAHAN John STENGER | 2020 | 智慧农业(中英文)2020，2，3： | 6 |
| 8 | Mild closed head traumatic brain injury-induced changes in monoamine neurotransmitters in the trigeminal subnuclei of a rat model:mechanisms underlying orofacial allodynias and headache显示文摘Our recent findings have demonstrated that rodent models of closed head traumatic brain injury exhibit comprehensive evidence of progressive and enduring orofacial allodynias, a hypersensitive pain response induced by non-painful stimulation. These allodynias, tested using thermal hyperalgesia, correlated with changes in several known pain signaling receptors and molecules along the trigeminal pain pathway, especially in the trigeminal nucleus caudalis. This study focused to extend our previous work to investigate the changes in monoamine neurotransmitter immunoreactivity changes in spinal trigeminal nucleus oralis, pars interpolaris and nucleus tractus solitaries following mild to moderate closed head traumatic brain injury, which are related to tactile allodynia, touch-pressure sensitivity, and visceral pain. Our results exhibited significant alterations in the excitatory monoamine, serotonin, in spinal trigeminal nucleus oralis and pars interpolaris which usually modulate tactile and mechanical sensitivity in addition to the thermal sensitivity. Moreover, we also detected a robust alteration in the expression of serotonin, and inhibitory molecule norepinephrine in the nucleus tractus solitaries, which might indicate the possibility of an alteration in visceral pain, and existence of other morbidities related to solitary nucleus dysfunction in this rodent model of mild to moderate closed head traumatic brain injury. Collectively, widespread changes in monoamine neurotransmitter may be related to orofacial allodynhias and headache after traumatic brain injury. | Golam Mustafa Jiamei Hou Rachel Nelson Shigeharu Tsuda Mansura Jahan Naweed S.Mohammad Joseph V.Watts Floyd J.Thompson Prodip Bose | 2017 | Neural Regeneration Research2017，12，6： | 5 |

| 14 | Chemical characterization and source apportionment of PM_(1) and PM_(2.5) in Tianjin, China: Impacts of biomass burning and primary biogenic sources显示文摘The submicron particulate matter(PM_(1))and fine particulate matter(PM_(2.5))are very important due to their greater adverse impacts on the natural environment and human health.In this study,the daily PM_(1) and PM_(2.5) samples were collected during early summer 2018 at a sub-urban site in the urban-industrial port city of Tianjin,China.The collected samples were analyzed for the carbonaceous fractions,inorganic ions,elemental species,and specific marker sugar species.The chemical characterization of PM_(1) and PM_(2.5) was based on their concentrations,compositions,and characteristic ratios(PM_(1)/PM_(2.5),AE/CE,NO3^-/SO4^2-,OC/EC,SOC/OC,OM/TCA,K^+/EC,levoglucosan/K^+,V/Cu,and V/Ni).The average concentrations of PM_(1) and PM_(2.5) were 32.4μg/m and 53.3μg/m^3,and PM_(1) constituted 63%of PM_(2.5) on average.The source apportionment of PM_(1) and PM_(2.5) by positive matrix factorization(PMF)model indicated the main sources of secondary aerosols(25%and 34%),biomass burning(17%and 20%),traffic emission(20%and 14%),and coal combustion(17%and 14%).The biomass burning factor involved agricultural fertilization and waste incineration.The biomass burning and primary biogenic contributions were determined by specific marker sugar species.The anthropogenic sources(combustion,secondary particle formation,etc)contributed significantly to PM_(1) and PM_(2.5),and the natural sources were more evident in PM_(2.5).This work significantly contributes to the chemical characterization and source apportionment of PM_(1) and PM_(2.5) in near-port cities influenced by the diverse sources. | Jahan Zeb Khan Long Sun Yingze Tian Guoliang Shi Yinchang Feng | 2021 | Journal of Environmental Sciences2021，33，1： | 3 |

| 18 | A rapid synthesis of high surface area PdRu nanosponges:Composition-dependent electrocatalytic activity for formic acid oxidation显示文摘Here, Pd Ru nanoparticle networks(NPNs) with various compositions were synthesized through an inexpensive method in water as a green solvent, at different ratios of the H_2PdCl_4 and RuCl_3 precursors. This is a fast, room temperature and surfactant free strategy which is able to form high surface area metal nanosponges with a three-dimensional(3D) porous structure. The structure of as-prepared nanosponges was characterized using the techniques of field emission scanning electron microscopy(FESEM), energy dispersive spectroscopy(EDS) and cyclic voltammetry(CV). Then, the electrocatalytic activities of Pd Ru NPNs towards formic acid oxidation were examined by electrochemical measurements including CV,chronoamperometry, and electrochemical impedance spectroscopy(EIS). Based on studies, it was found that the current density of formic acid oxidation(FAO) is strongly dependent on the composition of Pd Ru NPNs. The best performance was realized for Pd_4Ru_1 NPNs compared to monometallic Pd counterpart and other bimetallic NPNs which might be ascribed to the role of Ru in the decrease of CO adsorption strength on the catalyst and consequently the priority of formic acid oxidation through the direct pathway. The Pd_4Ru_1 NPNs also showed the maximum current density and stability in chronoamperometric measurements. In addition, comparative studies were performed between as-prepared NPNs and CNTs-supported Pd nanoparticles(Pd NPs/CNTs). The present results demonstrated the unique structural advantages of NPNs compared to individual Pd NPs supported on the CNT which leads to the promising performance of NPNs as supportless catalysts for the oxidation of formic acid. | Ehteram Hasheminejad Reza Ojani Jahan Bakhsh Raoof | 2017 | Journal of Energy Chemistry2017，26，4： | 2 |
| 19 | Regional Impact of Cyclone Sidr in Bangladesh: A Multi-Sector Analysis显示文摘This research investigates the impact of cyclone Sidr on six regional economic systems of Bangladesh. The study uses secondary data on direct damages and corresponding changes in consumer spending and public/private investment expenditure. It employs input–output modeling and simulates the changes in national and regional output,income, and employment due to cyclone Sidr. Our findings indicate that coastal regions of Bangladesh—Barisal,Chittagong, and Khulna—are more vulnerable to cyclone disaster than are other parts of the country. The cycloneinduced loss of output is highest for Chittagong Division and income and employment losses are greatest in Barisal Division. The most affected sectors are housing services,agriculture, construction, and industrial activities. But sectoral losses vary widely across the regions. This research also finds that the present state of consumer spending and investment expenditure is not great enough to handle cyclone-induced output, income, and employment losses. It argues that investment decisions must consider regional patterns of output, income, and employment losses in different economic sectors to ensure cyclone-resilient development in Bangladesh. | Afsana Haque Sarwar Jahan | 2016 | International Journal of Disaster Risk Science2016，7，3： | 2 |
| 20 | Antifertility Activity of Hydroalcoholic Extract of Ocimum Basilicum Linn. Leaves on Female Wistar Rats显示文摘Objective To determine the effect of hydroalcoholic extract of Ocimum basilicum Linn. leaves on ovulation, implantation and maintenance of pregnancy in adult female cyclic Wistar rats. Methods Ocimum basilicum leaves extract (364 mg/kg and 624 mg/kg) was screened for its antiovulatory, antiimplantation and abortifacient activities. Vaginal smear of each rat was monitored daily during the 15-day treatment of the first experiment. Estimation of cholesterol in ovarian tissue and its histology was carried out to confirm its antiovulatory activity. In the second and third experiments, animals received treatment from 1st to 7th and 8th to 16th day of pregnancy, respectively. The number of implantations and litter size were determined through laparotomy on 10th and 20th day of pregnancy, respectively in two tests. The treated groups were compared with pain control. Results A significant increase in duration of estrus cycle and diestrus phase was observed (P<0.001). A significant decrease in ovarian weight and notable increase in ovarian tissue cholesterol level was also observed (P<0.001). Weight of uterus in treated group was found to be decreased. Histological report showed presence of large corpora lutea in ovarian parenchyma. Neither antiimplantation nor abortifacient effect was observed in rats treated with both the doses of extract. Conclusion Hydroalcoholic extract of Ocimum basilicum interferes normal ovulation by disrupting the estrus cycle and prolonging diestrus phase thus, has a potential of being developed into a female contraceptive. | Alia Bilal Nasreen Jahan Ajij Ahmed Saima Naaz Bilal Shahida Habib | 2013 | Journal of Reproduction and Contraception2013，24，1： | 2 |
