| 1 | Adsorption of Folic Acid on the Single-walled Carbon Nanotubes: AIM and NBO Analyses via DFT显示文摘In the present work,the behavior of folic acid(FA) molecule adsorbed onto single-walled carbon nanotube(SWCNT) was examined using the DFT-B3LYP/6-31G* level.In order to obtain information about the binding features of SWCNT as adsorbent with FA molecule,several studies,including the structural and electronic parameters and also the Atoms in Molecules(AIM) analysis,were performed.It was observed that the FA molecule via hydrogen bond prefers to adsorb on SWCNT with adsorption energy of about-18.70 kcal/mol.The molecular orbitals(HOMO and LUMO),natural bond orbital(NBO) analysis,and density of states(DOS) plot indicated that a charge about 0.032 | e | is transferred from the FA molecule to the nanotube.After solvation energy calculations,it was found that the presence of a polar solvent causes an increase in FA adsorption on the single-walled carbon nanotube.Topological features such as electron energy density(Hc) and Laplacian of the electron density(2ρc) demonstrate partial covalent nature for H(116)…O(10) interaction in the FA/SWCNT complex.According to the calculated results,the single-walled carbon nanotubes are expected to be a potential efficient adsorbent for the adsorption of folic acid drug and also can be used as a suitable drug delivery vehicle within biological systems. | Shahla Hamedani Shahram Moradi Hossein Aghaie | 2015 | Chinese Journal of Structural Chemistry2015，34，8： | 6 |
| 2 | Short Term Influence of Organic and Inorganic Fertilizer on Soil Microbial Biomass and DNA in Summer and Spring显示文摘The present study was conducted to see the short term impact of organic and inorganic fertilizers on soil microbial biomass both in spring and summer. Also aimed to observe the correlation between soil microbial biomass and soil DNA. The study concluded that type of fertilizer might alter the soil microbial biomass and DNA contents. In soil treated with organic fertilizers resulted in higher concentrations of microbial biomass and DNA contents in summer as compared to spring dute to increase in temperature. Correspondingly, in case of inorganic fertilizer, concentrations of soil microbial biomass and DNA detected higher in summer instead of spring. The statistical correlation between soil microbial biomass, DNA and ODR in spring and summer along with organic and inorganic fertilizers were calculated highly significant(p>0.01). This study demonstrated the impact of fertilizers and seasonal variations on soil microbial biomass and also revealed significant correlation between soil microbial biomass and soil DNA. | Khalil ur Rehman Zhang Ying Shahla Andleeb Zhao Jiang Erinle Kehinda Olajide | 2016 | Journal of Northeast Agricultural University(English Edition)2016，23，1： | 4 |

| 4 | Molecular Structure and Theoretical Thermodynamic Study of Folic Acid Based on the Computational Approach显示文摘In our previous work, we studied the interaction of folic acid, FA, molecule with singlewalled carbon nanotube and the related binding energies with other related parameters. Now, in order to extend our study with respect to the other structural properties of folic acid molecule and its thermodynamic properties, we optimized the structures of both neutral and zwitteronic forms of this molecule by using the DFT/B3 LYP method in the gas phase and then in different solvents. In addition, the electronic properties, such as the molecular orbital study(HOMO, LUMO, PDOS, and TDOS) and geometrical structure, were investigated by the above-mentioned method with 6-31G(d) basis set. The thermodynamic properties of both neutral and zwitterionic forms of the FA molecule at different temperature have been calculated. Natural bond orbital(NBO) analysis has been done to study the stability of the molecule arising from charge delocalization. | Shahla Hamedani Hossein Aghaie | 2015 | Chinese Journal of Structural Chemistry2015，34，9： | 3 |
| 5 | Acoustics in urban parks:Does the structure of narrow urban parks matter in designing a calmer urban landscape?显示文摘Urban parks can function as a proper sink of noise pollution.However,lack of universally-agreed upon methodologies and differing urban conditions have fueled controversy surrounding the effectuation of this urban park function around the world.Hence,to address this controversy in narrow urban parks(with a mean width of∼109 m)in Isfahan City,Central Iran,noise levels(Lq30)were measured along two longitudinal transects placed along the interior northern river-and adjacent to the southern edge of the parks bordered by a heavily-conjected road.We used statistical tests and models to determine the association of noise levels measured along the northern transect with the distance to,and the intensity of noise emitted from,the road,vegetation biomass,and vegetation height within two 50 and 100 m buffer rings drawn around northern sites and the richness of bird species.The average Lq30 values differed significantly between the southern(∼73.21 dB)and northern(∼66.43 dB)transects and correlated negatively with species richness(r(98)=−0.324,p<0.01).Three variables including mean NDVIwithin the 100 m buffer ring,distance from the road and mean Lq30 values of the nearest three southern sites were included to build the best predictive multiple-linear regression model through the step-wise procedure with r2 of 0.52.These findings suggest that further attempts aiming to alleviate the parks’interior noise level should be attentive to distance to road,traffic at the nearest road part,and the interior vegetation characteristics. | Shahla Tashakkor Atefeh Chamani Mozhgan Ahmadi Nadoushan Minoo Moshtaghie | 2020 | Frontiers of Earth Science2020，14，3： | 2 |
| 6 | Influence of Soil pH and Temperature on Atrazine Bioremediation显示文摘Present study was conducted to clarify soil pH and temperature influence on different atrazine bioremediation techniques. For this purpose, sodium citrate, Arthrobactor sp. strain DNS10, sawdust and animal manure were selected to clarify their atrazine remediation efficiency under pH 5, 7 and 9 and temperatures 20, 30 and 40℃, respectively. Results showed that atrazine remediation was generally optimized at pH 7 and 30℃ for all the treatments except sodium citrate as soil treated with sawdust was not temperature dependant, but at pH 5 remediation process was determined slower. Atrazine remediation in soil with no additional amendment was only 34%, while in soil treated with sawdust, DNS10, sodium citrate and animal manure were 75.17%, 89%, 74.17% and 76.83% at optimized pH and temperature. Overall atazine removal rate was significantly(≥0.01) higher with increasing in temperature at all the selected pH. | Shahla Andleeb Zhao Jiang Khalil ur Rehman Erinle Kehinda Olajide Zhang Ying | 2016 | Journal of Northeast Agricultural University(English Edition)2016，23，2： | 2 |

| 8 | Potentially harmful metals,and health risk evaluation in groundwater of Mardan,Pakistan:Application of geostatistical approach and geographic information system显示文摘This study investigates the values of pH,total dissolved solids(TDS),elevation,oxidative reduction potential(ORP),temperature,and depth,while the concentrations of Br,and potentially harmful metals(PHMs)such as Cr,Ni,Cd,Mn,Cu,Pb,Co,Zn,and Fe in the groundwater samples.Moreover,geographic information system(GIS),XLSTAT,and IBM SPSS Statistics 20 software were used for spatial distribution modeling,principal component analysis(PCA),cluster analysis(CA),and Quantile-Quantile(Q-Q)plotting to determine groundwater pollution sources,similarity index,and normal distribution reference line for the selected parameters.The mean values of pH,TDS,elevation,ORP,temperature,depth,and Br were 7.2,322 mg/L,364 m,188 mV,29.6℃,70 m,0.20 mg/L,and PHMs like Cr,Ni,Cd,Mn,Cu,Pb,Co,Zn,and Fe were 0.38,0.26,0.08,0.27,0.36,0.22,0.04,0.43 and 0.86 mg/L,respectively.PHMs including Cr(89%),Cd(43%),Mn(23%),Pb(79%),Co(20%),and Fe(91%)exceeded the guideline values set by the world health organization(WHO).The significant R^(2)values of PCA for selected parameters were also determined(0.62,0.67,0.78,0.73,0.60,0.87,-0.50,0.69,0.70,0.74,-0.50,0.70,0.67,0.79,0.59,and-0.55,respectively).PCA revealed three geochemical processes such as geogenic,anthropogenic,and reducing conditions.The mineral phases of Cd(OH)_(2),Fe(OH)_(3),FeOOH,Mn_(3)O_(4),Fe_(2)O_(3),MnOOH,Pb(OH)_(2),Mn(OH)_(2),MnO_(2),and Zn(OH)_(2)(-3.7,3.75,9.7,-5.8,8.9,-3.6,2.2,-4.6,-7.7,-0.9,and 0.003,respectively)showed super-saturation and under-saturation conditions.Health risk assessment(HRA)values for PHMs were also calculated and the values of hazard quotient(HQ),and hazard indices(HI)for the entire study area were increased in the following order:Cd>Ni>Cu>Pb>Mn>Zn>Cr.Relatively higher HQ and HI values of Ni,Cd,Pb,and Cu were greater than one showing unsuitability of groundwater for domestic,agriculture,and drinking purposes.The long-term ingestion of groundwater could also cause severe health concerns such as kidney,brain dysfunction,liver,stomach problems,and even cancer. | Abdur Rashid Muhammad Ayub Asif Javed Sardar Khan Xubo Gao Chengcheng Li Zahid Ullah Tariq Sardar Juma Muhammad Shahla Nazneen | 2021 | Geoscience Frontiers2021，12，3： | 2 |
| 9 | Micromorphological Evidences of Climatic Change in Yazd Region,Iran显示文摘The fact of, present is the key of the past, will help us to use paleosols properties as indicators of the ecological characteristics of past time, particularly the paleoclimate. In this respect the micromorphological properties showed to be a very good indicator. Therefore, for investigating of climate change in Ardakan-Yazd plain, Central Iran 9 pedons were digged and described. Yazd has an arid climate with less than 100 mm annual precipitation and more than 22°C mean annual temperature (Aridic-hyper thermic soil moisture and temperature regions, respectively). Based on the morphological and physicochemical analysis Arglic, Calcic and Gypsic diagnostic horizons have been distinguished in these soils. Thin section studied showed that the illuviated form of clay includes, infillings on channel, coating on pendant, on nodules and on grains, at lower depths and also juxtaposed calcite needles on void argillan at upper part of the profiles. Mineralogical result showed fine clay in arglic horizon, too. Considering depth and forms of these pedofeatures, we concluded that, the observed illuviated clays at lower depth must be the result of the more humid climate of the past, where the carbonates have been removed completely as pendant, nodules or coating to considerable depth, following processes, clay has been dispersed and also trans located to these depths. In contrast to these features, the juxtaposed needle calcite at the shallower depth is probably the result of drier climate of today. | Ruhollah Taghizadeh Mehrjardi Shahla Mahmoodi Ahmad Heidari Ali Akbarzadeh | 2009 | Journal of Mountain Science2009，6，2： | 2 |

| 11 | Changes in Growth,Photosynthetic Pigments,Cell Viability,Lipid Peroxidation and Antioxidant Defense System in Two Varieties of Chickpea(Cicer arietinum L.)Subjected to Salinity Stress显示文摘Salinity is one of the most severe abiotic stresses for crop production.The present study investigates the salinityinduced modulation in growth indicators,morphology and movement of stomata,photosynthetic pigments,activity of carbonic anhydrase as well as nitrate reductase,and antioxidant systems in two varieties of chickpea(Pusa-BG5023,and Pusa-BGD72).On 20^(th) day of sowing,plants were treated with varying levels of NaCl(0,50,100,150 and 200 mM)followed by sampling on 45 days of sowing.Recorded observations on both the varieties reveal that salt stress leads to a significant decline in growth,dry biomass,leaf area,photosynthetic pigments,protein content,stomatal behavior,cell viability,activity of nitrate reductase and carbonic anhydrase with the rise in the concentration of salt.However,quantitatively these changes were less in Pusa-BG5023 as compared to Pusa-BGD72.Furthermore,salinity-induced oxidative stress enhanced malondialdehyde content,superoxide radicals,foliar proline content,and the enzymatic activities of superoxide dismutase,catalase,and peroxidase.The variety Pusa-BGD72 was found more sensitive than Pusa-BG5023 to salt stress.Out of different graded concentrations(50,100,150 and 200 mM)of sodium chloride,50 mM was least toxic,and 200 mM was most damaging.The differential behavior of these two varieties measured in terms of stomatal behavior,cell viability,photosynthetic pigments,and antioxidant defense system can be used as prospective indicators for selection of chickpea plants for salt tolerance and sensitivity. | Zeenat Mushtaq Shahla Faizan Basit Gulzar Humira Mushtaq Sayyada Bushra Alisha Hussain Khalid Rehman Hakeem | 2022 | Phyton-International Journal of Experimental Botany2022，91，1： | 1 |

| 20 | Design of a heterosubtypic epitope-based peptide vaccine fused with hemokinin-1 against influenza viruses显示文摘Influenza viruses continue to emerge and re-emerge, posing new threats for public health. Control and treatment of influenza depends mainly on vaccination and chemoprophylaxis with approved antiviral drugs. Identification of specific epitopes derived from influenza viruses has significantly advanced the development of epitope-based vaccines. Here, we explore the idea of using HLA binding data to design an epitope-based vaccine that can elicit heterosubtypic T-cell responses against circulating H7N9, H5N1, and H9N2 subtypes. The hemokinin-1(HK-1) peptide sequence was used to induce immune responses against the influenza viruses. Five conserved high score cytotoxic T lymphocyte(CTL) epitopes restricted to HLA-A*0201-binding peptides within the hemagglutinin(HA) protein of the viruses were chosen, and two HA CTL/HK-1 chimera protein models designed. Using in silico analysis, which involves interferon epitope scanning, protein structure prediction, antigenic epitope determination, and model quality evaluation, chimeric proteins were designed. The applicability of one of these proteins as a heterosubtypic epitopebased vaccine candidate was analyzed. | Shahla Shahsavandi Mohammad Majid Ebrahimi Kaveh Sadeghi Homayoon Mahravani | 2015 | Virologica Sinica2015，30，3： | 1 |
