| 1 | Microbiologic spectrum of acute and chronic dacryocystitis显示文摘AIM:To report the microbiological spectrum of acute and chronic dacrocystitis.METHODS:Retrospective study on 100 patients who presented to the ophthalmic plastic clinic of a tertiary eye care center from May 2011 and April 2013 with acute and chronic dacryocystitis was reviewed for demographic and microbiological profile. The culture results and organisms isolated were recorded.RESULTS:Sixty patients had acute onset and the remaining 40 patients had chronic onset dacryocystitis.The female to male ratio was 1.78. The mean age of patients was 44 y. Gram-positive organisms were the most commonly isolated accounting for 54%, and the commonest species isolated was S. aureus in 26%.Percentage of gram positive cultures was higher in chronic dacryocystitis than acute ones(82% vs 48% of positive cultures; P =0.003). Also in culture positive acute dacryocystitis, gram negative species were found in 52%of eyes but only in 18% of chronic dacryocystitis.CONCLUSION:Gram negative bacteria, culture negative samples, unusual and more virulent organisms are more common in acute dacryocystitis than chronic ones. The results of this study have significant bearing on the treatment of patients with dacrocystitis. | Bahram Eshraghi Parisa Abdi Mohammadreza Akbari Masoud Aghsaei Fard | 2014 | International Journal of Ophthalmology(English edition)2014，7，5： | 11 |
| 2 | Soil Organic Carbon Pools in Particle-Size Fractions as Affected by Slope Gradient and Land Use Change in Hilly Regions,Western Iran显示文摘This study was conducted to explore the effects of topography and land use changes on particulate organic carbon(POC),particulate total nitrogen(PTN),organic carbon(OC) and total nitrogen(TN) associated with different size primary particle fractions in hilly regions of western Iran.Three popular land uses in the selected site including natural forest(NF),disturbed forest(DF) and cultivated land(CL) and three slope gradients(0-10 %,S1,10-30 %,S2,and 30-50%,S3) were employed as the basis of soil sampling.A total of 99 soil samples were taken from the 0-10 cm surface layer in the whole studied hilly region studied.The results showed that the POC in the forest land use in all slope gradients was considerably more than the deforested and cultivated lands and the highest value was observed at NF-S1 treatment with 9.13%.The values of PTN were significantly higher in the forest land use and in the down slopes(0.5%) than in the deforested and cultivated counterparts and steep slopes(0.09%) except for the CL land use.The C:N ratios in POC fraction were around 17-18 in the forest land and around 23 in the cultivated land.In forest land,the silt-associated OC was highest among the primary particles.The enrichment factor of SOC,EC,was the highest for POC.For the primary particles,EC of both primary fractions of silt and clay showed following trend for selected land uses and slope gradients:CL> DF> NF and S3 > S2> S1.Slope gradient of landscape significantly affected the OC and TN contents associated with the silt and clay particles,whereas higher OC and TN contents were observed in lower positions and the lowest value was measured in the steep slopes.Overall,the results showed that native forest land improves soil organic carbon storage and can reduce the carbon emission and soil erosion especially in the mountainous regions with high rainfall in west of Iran. | Parisa Mokhtari KARCHEGANI Shamsollah AYOUBI Mohammad Reza MOSADDEGHI Naser HONARJOO | 2012 | Journal of Mountain Science2012，9，1： | 10 |
| 3 | Effects of Salinity and Potassium Application on Antioxidant Enzyme Activities and Physiological Parameters in Pearl Millet显示文摘A plot culture experiment was conducted in a greenhouse at University of Zabol,Iran,to study the effects of different salinity levels and potassium supply on pearl millet.The experiment was laid out in a completely randomized factorial design with three replicates.Potassium sulfate was used as the potassium source.The rates of potassium treatments were 0,100,and 200 kg ha-1.Pearl millet was subjected to different salinity levels(0,4,8,and 12 ds m-1) through addition of NaCl to irrigation water.Results showed that the increase in the salt concentration from control to 12 ds m-1 decreased grain yield(38.7%) of millet plants.In this study,we found a negative relationship between potassium and proline accumulation at vegetative(r2=-0.75**) and reproductive stage(r2=-0.66**) in millet plants.Salt stress remarkably elevated the activities of CAT and GPX antioxidant enzymes at vegetative and reproductive stages.Furthermore,potassium application had significant effect on grain yield and increased it about 10.6% at the highest salinity treatment(12 ds m-1).Though,potassium treatment increased antioxidant activity in millet plants,it had no significant effect on proline content in leaves.Salinity treatment decreased potassium uptake but application potassium increased potassium content in leaves at two stages. | Mostafa Heidari Parisa Jamshidi | 2011 | Agricultural Sciences in China2011，10，2： | 6 |
| 4 | An in vitro evaluation of novel NHA/zircon plasma coating on 316L stainless steel dental implant显示文摘The surface characteristics of an implant that influence the speed and strength of osseointegration include crystal structure and bioactivity. The aim of this study was to evaluate the bioactivity of a novel natural hydroxyapatite/zircon(NHA/zircon) nanobiocomposite coating on 316L stainless steel(SS) dental implants soaking in simulated body fluid. A novel NHA/zircon nanobiocomposite was fabricated with 0(control),5, 10, and 15 wt% of zircon in NHA using ball mill for 1 h. The composite mixture was coated on SS implants using a plasma spray method.Scanning electron microscopy(SEM) was used to evaluate surface morphology, and X-ray diffraction(XRD) was used to analyze phase composition and crystallinity(Xc). Further, calcium ion release was measured to evaluate the coated nanobiocomposite samples. The prepared NHA/zircon coating had a nanoscale morphological structure with a mean crystallite size of 30–40 nm in diameter and a bone-like composition,which is similar to that of the biological apatite of a bone. For the prepared NHA powder, high bioactivity was observed owing to the formation of apatite crystals on its surface. Both minimum crystallinity(Xc=41.1%) and maximum bioactivity occurred in the sample containing 10 wt% of zircon because of minimum Xcand maximum biodegradation of the coating sample. | Ebrahim Karamian Mahmood Reza Kalantar Motamedi Amirsalar Khandan Parisa Soltani Sahel Maghsoudi | 2014 | Progress in Natural Science:Materials International2014，24，2： | 6 |
| 5 | 摩擦堆焊AA2024-Ag复合材料的显微组织表征与力学性能显示文摘研究银对摩擦堆焊AA2024铝合金涂层显微组织、力学性能和电导率的影响。银添加方式为先在AA2024铝合金耗材棒横截表面钻孔,再在孔内填充银粉,其添加量为5.3、10.6和16.0%(质量分数)。结果表明,固溶强化、析出相和含银金属间化合物的形成降低晶粒生长的驱动力,从而降低涂层中的晶粒尺寸。经人工时效热处理后,含0%Ag(质量分数)涂层的电导率提高了4.15%(IACS),而含16.0%Ag(质量分数)涂层的电导率降低2.15%(IACS)。当考虑线性关系时,在银含量Ag增加1%(质量分数)的条件下,涂层的强度和硬度分别增加1.8%和1.0%。Al6(Cu,Ag)Mg4析出相的形成比富Ag金属间化合物的形成对强化的影响更大。 | Parisa PIRHAYATI Hamed JAMSHIDI AVAL | 2020 | Transactions of Nonferrous Metals Society of China2020，30，7： | 5 |

| 7 | New trends in molecular and cellular biomarker discovery for colorectal cancer显示文摘Colorectal cancer(CRC) is the third leading cause of cancer death worldwide, which is consequence of multistep tumorigenesis of several genetic and epigenetic events. Since CRC is mostly asymptomatic until it progresses to advanced stages, the early detection using effective screening approaches, selection of appropriate therapeutic strategies and efficient follow-up programs are essential to reduce CRC mortalities. Biomarker discovery for CRC based on the personalized genotype and clinical information could facilitate the classification of patients with certain types and stages of cancer to tailor preventive and therapeutic approaches. These cancer-related biomarkers should be highly sensitive and specific in a wide range of specimen(s)(including tumor tissues, patients' fluids or stool). Reliable biomarkers which enable the early detection of CRC, can improve early diagnosis, prognosis, treatment response prediction, and recurrence risk. Advances in our understanding of the natural history of CRC have led to the development of different CRC associated molecular and cellular biomarkers. This review highlights the new trends and approaches in CRC biomarker discovery, which could be potentially used for early diagnosis, development of new therapeutic approaches and follow-up of patients. | Parisa Aghagolzadeh Ramin Radpour | 2016 | World Journal of Gastroenterology2016，22，25： | 5 |
| 8 | The emergence of drug resistant HIV variants and novel anti-retroviral therapy显示文摘After its identification in 1980s,HIV has infected more than 30 million people worldwide.Inthe era of highly active anti-retroviral therapy,anti-retroviral drug resistance results frominsufficient anti-retroviral pressure,which may lead to treatment failure.Preliminary studiessupport the idea that anti-retroviral drug resistance has evolved largely as a result of low-adherence of patients to therapy and extensive use of anti-retroviral drugs in the developedworld;however,a highly heterogeneous horde of viral quasi-species are currently circulating indeveloping nations.Thus,the prioritizing of strategies adopted in such two worlds should be quitedifferent considering the varying anti-retroviral drug resistance prevalence.In this article,weexplore differences in anti-retroviral drug resistance patterns between developed and developingcountries,as they represent two distinct ecological niches of HIV from an evolutionary standpoint. | Koosha Paydary Parisa Khaghani Sahra Emamzadeh-Fard Seyed Ahmad Seyed Alinaghi Kazem Baesi | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，7： | 5 |

| 10 | Circulation intensity and axial dispersion of non-cohesive solid particles in a V-blender via DEM simulation显示文摘In this study,discrete element method(DEM) was employed to simulate the movement of non-cohesive mono-dispersed particles in a V-blender along with particle-particle and particle-boundary interactions.To validate the model,DEM results were successfully compared to positron emission particle tracking(PEPT) data reported in literature.The validated model was then utilized to explore the effects of rotational speed and fill level on circulation intensity and axial dispersion coefficient of non-cohesive particles in the V-blender.The results showed that the circulation intensity increased with an increase in the rotational speed from 15 to 60rpm.As the fill level increased from 20%to 46%,the circulation intensity decreased,reached its minimum value at a fill level of 34%for all rotational speeds,and did not change significantly at fill levels greater than 34%.The DEM results also revealed that the axial dispersion coefficient of particles in the V-blender was a linear function of the rotational speed.These trends were in good agreement with the experimentally determined values reported by previous researchers. | Parisa Tahvildarian Farhad Ein-Mozaffari Simant R.Upreti | 2013 | Particuology2013，11，6： | 3 |

| 16 | Phytoremediation of engineered nanoparticles using aquatic plants: Mechanisms and practical feasibility显示文摘Certain plants have demonstrated the capability to take up and accumulate metals,thus offering the potential to remediate metal-contaminated water and sediment.Several aquatic species have further been identified which can take up metal and metal oxide engineered nanoparticles(ENPs).It is important to evaluate if aquatic plants exhibiting potential for metal phytoremediation can be applied to remediation of metallic ENPs.Understanding the interactions between ENPs and aquatic plants,and evaluating possible influences on metal uptake and phytoremediation processes is therefore essential.This review article will address the feasibility of green plants for treatment of ENP-affected aquatic ecosystems.Discussion will include common types of ENPs in current use;transformations of ENPs in aquatic systems;the importance of microorganisms in supporting plant growth;ENP entry into the plant;the influence of microorganisms in promoting plant uptake;and recent findings in phytoremediation of ENP-affected water,including applications to constructed wetlands. | Parisa Ebrahimbabaie Weeradej Meeinkuirt John Pichtel | 2020 | Journal of Environmental Sciences2020，32，7： | 2 |
| 17 | Co-adsorption of gaseous benzene, toluene, ethylbenzene,m-xylene(BTEX) and SO_2 on recyclable Fe_3O_4 nanoparticles at 0–101% relative humidities显示文摘We herein used Fe3O4 nanoparticles(NPs) as an adsorption interface for the concurrent removal of gaseous benzene, toluene, ethylbenzene and m-xylene(BTEX) and sulfur dioxide(SO2), at different relative humidities(RH). X-ray diffraction, Brunauer–Emmett–Teller, and transmission electron microscopy were deployed for nanoparticle surface characterization.Mono-dispersed Fe3O4(Fe2O3·Fe O) NPs synthesized with oleic acid(OA) as surfactant, and uncoated poly-dispersed Fe3O4 NPs demonstrated comparable removal efficiencies.Adsorption experiments of BTEX on NPs were measured using gas chromatography equipped with flame ionization detection, which indicated high removal efficiencies(up to(95 ± 2)%) under dry conditions. The humidity effect and competitive adsorption were investigated using toluene as a model compound. It was observed that the removal efficiencies decreased as a function of the increase in RH, yet, under our experimental conditions, we observed(40 ± 4)% toluene removal at supersaturation for Fe3O4 NPs, and toluene removal of(83 ± 4)% to(59 ± 6)%, for OA-Fe3O4 NPs. In the presence of SO2, the toluene uptake was reduced under dry conditions to(89 ± 2)% and(75 ± 1)% for the uncoated and coated NPs, respectively, depicting competitive adsorption. At RH > 100%,competitive adsorption reduced the removal efficiency to(27 ± 1)% for uncoated NPs whereas OA-Fe3O4 NPs exhibited moderate efficiency loss of(55 ± 2)% at supersaturation.Results point to heterogeneous water coverage on the NP surface. The magnetic property of magnetite facilitated the recovery of both types of NPs, without the loss in efficiency when recycled and reused. | Connie Z.Ye Parisa A.Ariya | 2015 | Journal of Environmental Sciences2015，27，5： | 2 |

| 19 | Severe acute respiratory syndrome coronavirus 2 infection: Role of interleukin-6 and the inflammatory cascade显示文摘Since December 2019,a novel coronavirus that represents a serious threat to human lives has emerged.There is still no definite treatment for severe cases of the disease caused by this virus,named coronavirus disease 2019(COVID-19).One of the most considered treatment strategies targets the exaggerated immune regulator,and interleukin(IL)-6 is a crucial pro-inflammatory mediator.Severe acute respiratory syndrome coronavirus 2(SARSCoV-2)cases show an elevated level of IL-6 related to disease severity.IL-6 activity can be inhibited by the following:IL-6 itself,IL-6 signaling pathways such as Janus kinase and signal transducer and activator of transcription(JAK-STAT),gp130,IL-6R,and downstream activated ILs,such as IL-17 and IL-6 cytokine.Currently,according to these studies and their results,IL-6 blockade with anti-IL-6 or its receptor antibodies such as tocilizumab in COVID-19 is beneficial in severe cases and may reduce the mortality rate.JAK-STAT inhibitors block the cytokine storm by inhibiting several crucial pro-inflammatory mediators such as TNF-αand IL-6 and have shown various results in clinical trials.IL-6 induces IL-17 secretion,and IL-17 is involved in the pathogenesis of inflammatory processes.Clinical trials of anti-IL-17 drugs are currently recruiting,and anti-gp130 antibody is preclinical.However,this agent has shown positive effects in inflammatory bowel disease clinical trials and could be tested for SARS-CoV-2.This study aimed to review the role of IL-6 in the cytokine storm and studies regarding IL-6 and blockade of its inflammatory pathways in COVID-19 to determine if any of these agents are beneficial for COVID-19 patients. | Mohaddeseh Bahmani Rojin Chegini Elham Ghanbari Elham Sheykhsaran Parisa Shiri Aghbash HamedEbrahimzadeh Leylabadlo Ehsan Moradian Amir Masoud Kazemzadeh Houjaghan Hossein Bannazadeh Baghi | 2022 | World Journal of Virology2022，11，3： | 2 |
