| 1 | A systematic review of effi cacy and tolerability of mebeverine in irritable bowel syndrome显示文摘We evaluated the eff icacy and tolerability of mebeverine, a musculotropic antispasmodic agent, in irritable bowel syndrome (IBS) and compared its usual dosages by meta-analysis. Medical databases and all relevant literature were searched from 1965 to June 2009 for any placebo-controlled clinical trials of mebeverine, using search terms such as mebeverine, clinical trials, and IBS. Eight randomized trials met our criteria, including six trials that compared mebeverine with placebo and two that compared mebeverine tablets with capsules. These eight trials included 555 patients randomized to receive either mebeverine or placebo with 352 (63%)women and 203 (37%) men in all subtypes of IBS. The pooled relative risk (RR) for clinical improvement of mebeverine was 1.13 (95% CI: 0.59-2.16, P = 0.7056) and 1.33 (95% CI: 0.92-1.93, P = 0.129) for relief of abdominal pain. The efficacy of mebeverine 200 mg compared to mebeverine 135 mg indicated RRs of 1.12 (95% CI: 0.96-1.3, P = 0.168) for clinical or global improvement and 1.08 (95% CI: 0.87-1.34, P = 0.463) for relief of abdominal pain. Thus, mebeverine is mostly well tolerated with no signif icant adverse effects; however, its eff icacy in global improvement of IBS is not statistically signif icant. | Mahnaz Darvish-Damavandi Shekoufeh Nikfar Mohammad Abdollahi | 2010 | World Journal of Gastroenterology2010，16，5： | 17 |
| 2 | Hepatitis C virus and type 2 diabetes显示文摘This review focuses on the relationship between hepatitis C virus(HCV) infection and glucose metabolism derangements.Cross-sectional and longitudinal studies have shown that the chronic HCV infection is associated with an increased risk of developing insulin resistance(IR) and type 2 diabetes(T2D).The direct effect of HCV on the insulin signaling has been analyzed in experimental models.Although currently available data should be considered as preliminary,HCV seems to affect glucose metabolism via mechanisms that involve cellular pathways that have been implicated in the host innate immune response.IR and T2D not only accelerate the histological and clinical progression of chronic hepatitis C,but also reduce the early and sustained virological response to interferon-alpha-based therapy.Thus,a detailed knowledge of the mechanisms underlying the HCV-associated glucose metabolism derangements is warranted,in order to improve the clinical management of chronic hepatitis C patients. | Francesco Negro Mahnaz Alaei | 2009 | World Journal of Gastroenterology2009，15，13： | 14 |
| 3 | 糖尿病患者血清胱抑素C和急性反应指标与视网膜病变严重程度相关性研究(英文)显示文摘目的:评估糖尿病视网膜病变(DR)严重程度与血清胱抑素C和急性时相反应指标的相关性,包括红细胞沉降率(ESR)和超敏C反应蛋白(hs-CRP)。方法:研究纳入了1mo内就诊的所有糖尿病视网膜病患者。患者均记录人口统计学数据。行眼科检查,同时检测糖化血红蛋白(Hb A1c)、ESR、hs-CRP和血清胱抑素C水平。结果:研究包括67例糖尿病患者,其中19例(28.3%)无视网膜病变患者,22例(32.8%)非增殖型视网膜病变患者和26例(38.8%)增殖型视网膜病变患者。三组间平均年龄、性别分布、平均糖尿病病程、高血压和血脂异常患病率、吸烟状况以及Hb A1c水平无明显差异。随着视网膜病变发展,平均血清胱抑素C水平显著提高,三组分别为1.1±0.48,1.22±0.38,1.71±0.92(P=0.007)。在多元回归分析中,仅血清胱抑素C与糖尿病视网膜病变严重程度有关(P=0.025)。结论:研究表明,在独立于急性时相反应指标,血清胱抑素C水平随DR加重升高。因此,该结论可作为初级医护人员区分高危患者的标志。 | Joobin Khadamy Gholamhossein Yaghoobi Abbas Hosseini Rad Mahnaz Najafi Saeed Reza Heydari Pardis Khademi | 2018 | 国际眼科杂志2018，18，3： | 8 |
| 4 | Effect of sex and rearing system on the quality and mineral content of fiber from raeini cashmere goats显示文摘The aim of this study was to compare the quality characteristics and mineral content of the fiber from male and female cashmere goats raised under different management systems. Male and female Raeini cashmere goats (<1.5 years of age, n = 48) were selected from flocks raised at a government breeding station or raised commercially under either rural or nomadic conditions. The staple length, cashmere fiber diameter, coefficient of variation for fiber diameter, percentage of cashmere in a fleece, percentage of guard hair in a fleece and cashmere tenacity averaged 4.6 ±0.1 cm, 18.0 ±0.1 m, 20.9 ± 0.4%, 66.1 ± 1.5%, 33.8 ± 1.5% and 1.8 ± 0.2 gf/tex, respectively. The sulfur, copper and zinc content of the cashmere averaged 2.8 ± 0.1%, 0.00065 ± 0.00002% and 0.01276 ± 0.00025%, respectively. Rearing method significantly affected staple length, coefficient of variation of fiber diameter, cashmere tenacity and copper content. Males had a higher coefficient of variation of fiber diameter and cashmere tenacity than females (P < 0.05). | Mehrdad Shamsaddini-Bafti Mahnaz Salehi Ali Maghsoudi Ali Mostafa Tehrani Farhad Mirzaei Syed Mojtaba Syed Momen | 2012 | Journal of Animal Science and Biotechnology2012，3，3： | 7 |
| 5 | Parameter analysis of a photonic crystal fiber with raised-core index profile based on effective index method显示文摘Photonic crystal fibers (PCFs) with a stepped raised-core profile and one layer equally spaced holes in the cladding are analyzed. Using effective index method and considering a raised step refractive index difference between the index of the core and the effective index of the cladding, we improve the characteristic parameters such as numerical aperture and V-parameter, and reduce its bending loss to about one tenth of a conventional PCF. Implementing such a structure in PCFs may be one step forward to achieve low loss PCFs for communication applications. | Faramarz E.Seraji Mahnaz Rashidi Vajieh Khasheie | 2006 | Chinese Optics Letters2006，4，8： | 7 |
| 6 | Relationship between Temperaments of Medicinal Plants and Their Major Chemical Compounds显示文摘Objective: To determine any relationship between temperaments of medicinal plants referred to traditional Iranian manuscripts and their major chemical compounds. Methods: Plants used in traditional Iranian medicine were categorized based on their major chemical compounds including alkaloids, phenolic compounds, and essential oils. Their temperaments were extracted from traditional herbal pharmacopeias of Iran. The possible relationship between major chemical compounds and temperaments of each group were evaluated. Results: Plants containing phenolic compounds as their major constituents are hot and dry temperaments except those contain tannins with cold and dry temperaments. Plants containing essential oils have hot and dry temperaments except those whose major essential oils with alcoholic structure which have cold and dry temperaments. Alkaloid-containing plants have cold and dry or hot and dry temperaments based on their alkaloidal structures. Conclusions: There is a close relationship between major chemical compounds of medicinal plants and their temperaments mentioned in traditional Iranian manuscripts. | Mohammad Reza Shams Ardekani Roja Rahimi Behjat Javadi Leila Abdi Mahnaz Khanavi | 2011 | Journal of Traditional Chinese Medicine2011，31，1： | 7 |
| 7 | In vitro assay for the anti-brucella activity of medicinal plants against tetracycline-resistant Brucella melitensis显示文摘Brucellosis, a zoonosis caused by four species of brucella, has a high morbidity. Brucella melitensis is the main causative agent of brucellosis in both human and small ruminants. As an alternative to conventional antibiotics, medicinal plants are valuable resources for new agents against antibiotic-resistant strains. The aim of this study was to investigate the usage of native plants for brucellosis treatment. For this purpose, the anti-brucella activities of ethanolic and methanolic extracts of Salvia sclarea, Oliveria decumbens, Ferulago angulata, Vitex pseudo-negundo, Teucrium polium, Plantago ovata, Cordia myxa, and Crocus sativus were assessed. The activity against a resistant Br. melitensis strain was determined by disc diffusion method at various concentrations from 50-400 mg/ml. Antibiotic discs were also used as a control. Among the evaluated herbs, six plant (Salvia sclarea, Oliveria decumbens, Ferulago angulata, Vitex pseudo-negundo, Teucrium polium, and Crocus sativus) showed anti-brucella activity. Oliveria de- cumbens was chosen as the most effective plant for further studies. A tested isolate exhibited resistance to tetracycline, nafcillin, oxacillin, methicillin, and colistin. Minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) values for Oliveria decumbens against resistant Br. melitensis were the same (5 mg/ml), and for gentamicin they were both 2 mg/ml. Time-kill kinetics for a methanolic extract of Oliveria decumbens was 7 h whereas for an ethanolic extract it was 28 h. Also, Oliveria decumbens extracts showed a synergistic effect in combination with doxycycline and tetracycline. In general, the similar values of MIC and MBC for Oliveria decumbens suggest that these extracts could act as bactericidal agents against Br. melitensis. In addition to Oliveria decumbens, Crocus sativus and Salvia sclarea also had good anti-brucella activity and these should be considered for further study. | Hossein MOTAMEDI Esmaeil DARABPOUR Mahnaz GHOLIPOUR Seyyed Mansour SEYYED NEJAD | 2010 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2010，11，7： | 6 |
| 8 | What factors affect length of hospital stay among trauma patients? A single-center study, Southwestern Iran显示文摘Purpose: Trauma is a major health concern. Length of hospital stay (LOS) has been targeted as an important metric to assess trauma care. This study aims to evaluate the risk factors that affect LOS among trauma patients in a trauma center in Southwestern Iran.Methods: This cross-sectional study was conducted on patients admitted to Rajaee Trauma Center, Shiraz, Iran between January 1, 2018 and December 30, 2018. The inclusion criteria were age above 15 years and having traffic accident injuries, including car, motorcycle and pedestrian injury mechanisms. The exclusion criteria were existing diseases including cardiovascular, cerebral, renal, and pulmonary diseases prior to this study, dead upon arrival or within 48 h after admission, and stay at the hospital for less than 6 h. The risk variables analyzed for prolonged LOS were age, gender, mechanism of traffic accident injury, infection during hospital stay, type of injury, injury severity score, surgery during hospitalization, and survival. Poisson regression was performed to evaluate the partial effects of each co- variate on trauma hospitalization (≥3 days as longer stay).Results: This study was conducted on 14,054 patients with traffic accident injury and the mean age was (33.89 ± 15.78) years. Additionally, 74.35% of the patients were male, with male to female ratio of 2.90. The result of Poisson regression indicated that male patients, higher age, combination of thoracic injuries, onset of infected sites, and surgery patients were more susceptible to have a longer LOS. Considering the site of injury, patients with face injuries followed by those with thorax injuries had the highest means of LOS (3.74 days and 3.36 days, respectively). Simultaneous existence of surgical inter- vention and infection in a patient had the greatest impact on prolonged LOS.Conclusion: This study identified that age, gender, mechanism of injury, infection, type of injury, survival, and ISS could lead to prolongation of LOS, but the affect can be reduced by eliminating modifiable risk factors. | Ali Kashkooe Mahnaz Yadollahi Forough Pazhuheian | 2020 | Chinese Journal of Traumatology2020，23，3： | 6 |
| 9 | 双眼屈光不正性弱视和远视的相关性研究(英文)显示文摘目的:探讨在远视、眼正位儿童中双眼屈光不正性弱视与远视患病率的关系。方法:选取56例两眼对称远视儿童,平均年龄5.5岁,分为两组,双眼远视≤+4.0D等效球镜组和双眼远视>+4.0D等效球镜组。评估两组双眼屈光不正性弱视的患病率,并进行比较。结果:在32例双眼远视≤+4.0D等效球镜组中,4例(13%)患双眼屈光不正性弱视;24例双眼远视>+4.0D等效球镜组中,15例(63%)患双眼屈光不正性弱视。统计学分析显示两组双眼屈光不正的儿童中弱视患病率有显著性差异(P<0.01)。结论:双眼屈光不正性弱视在双眼远视的儿童中并不罕见,尤其是当远视度数大于+4.0D等效球镜时。基于本次调查,双眼远视>+4.0D的儿童有13%~63%发展成两眼屈光不正性弱视。由此说明远视>+4.0D的儿童患两眼屈光不正性弱视的几率较大。 | Ali Rezaei Shokooh Farhad Adhami Moqadam Abdolhamid Najafi Youness Ghasemiy Mahnaz Vaezi MSc | 2012 | 国际眼科杂志2012，12，3： | 4 |

The L1–3 derivatives were found to be efficient ligands in the palladium-catalyzed Suzuki C–C coupling reactions in water. It was determined that with the use of L1–3 /Pd(OAc)2 system as a catalyst, aryl halides undergo Suzuki cross-couplings with arylboronic acids to give the desired products in moderate to excellent yields. | Mojtaba Amini Abbas Tarassoli Saeed Yousefi Sepideh Delsouz-Hafshejania Mina Bigdeli Mahnaz Salehifar | 2014 | Chinese Chemical Letters2014，25，1： | 3 |
| 12 | Silicon Affects Transcellular and Apoplastic Uptake of Some Nutrients in Plants显示文摘The positive effects of silicon(Si) on growth of plants have been well documented;however,the impact of Si on plant nutrient uptake remains unclear.The growth,nutrient content and uptake of wheat(Triticum aestivum L.),canola(Brassica napus L.) and cotton(Gossypium hirsutum L.) plants were evaluated with or without application of 1.5 mmol L^(-1) Si.Application of Si increased dry weights by 8%,30%and 30%and relative growth rate(RGR) by 10%,13%and 17%in the cotton,canola and wheat plants,respectively.The plant relative water content(RWC) was also increased,but the plant transpiration was decreased by Si application.The uptake and content of Ca^(2+) were 19%and 21%lower in the cotton and wheat plants with Si than those without Si,respectively;however,Si application increased both K^+ and Fe uptake and contents in all plant species.Silicon application reduced B uptake and content only in cotton and increased P and Zn^(2+) contents in all three plant species.The decrease in Ca^(2+) uptake by Si application was sustained even in the presence of metabolic inhibitors 2,4-dinitrophenol and sodium cyanide.Uptake of Ca^(2+) by Si application was enhanced or did not change when plant shoots were saturated with water vapor or their roots were exposed to low temperature.Thus,Si application increased the uptake of transcellularly transported elements like K^+,P,Zn^(2+) and Fe.In contrast,Ca2+ uptake which occurred via both apoplastic and transcellular pathways was decreased by Si application,possibly through reduction of apoplastic uptake.More efficient nutrient uptake might be another promoting effect of Si on plant growth. | Pooyan MEHRABANJOUBANI Ahmad ABDOLZADEH Hamid Reza SADEGHIPOUR Mahnaz AGHDASI | 2015 | Pedosphere2015，25，2： | 3 |

| 14 | Microfacies models and sequence stratigraphic architecture of the Oligocene-Miocene Qom Formation, south of Qom City, Iran显示文摘The OligoceneeMiocene Qom Formation has different depositional models in the Central Iran,SanandajeSirjan and Urumieh-Dokhtar magmatic arc provinces in Iran.The Kahak section of the Qom Formation in the Urumieh-Dokhtar magmatic arc has been studied,in order to determinate its microfacies,depositional model and sequence stratigraphy.The textural analysis and faunal assemblages reveal ten microfacies.These microfacies are indicative of five depositional settings of open marine,patch reef,lagoon,tidal flat and beach of the inner and middle ramp.On the basis of the vertical succession architecture of depositional system tracts,four third-order sequences have been recognized in the OligoceneeMiocene Kahak succession of Qom Formation.Based on the correlation charts,the transgression of the Qom Sea started from the southeast and continued gradually towards the north.This resulted in widespread northward development of the lagoon paleoenvironment in the Aquitanian-Burdigalian stages.Also,the sequence stratigraphic model of the OligoceneeMiocene Qom Formation has an architecture similar to those that have developed from OligoceneeMiocene global sea level changes. | Mahnaz Amirshahkarami Mahnaz Karavan | 2015 | Geoscience Frontiers2015，6，4： | 2 |
| 15 | Promising effect of Magliasa, a traditional Iranian formula, on experimental colitis on the basis of biochemical and cellular findings显示文摘AIM: To investigate the efficacy of Magliasa, a traditional Iranian formula, on experimental colitis. METHODS: After botanical authentication of herbal ingredients, formulation of Magliasa, quantitative determination of total glucosinolates and total phenolic content, and analysis of the thin layer chromatography profile were performed. Colitis was then induced in male rats by instillation of 2,4,6-trinitrobenzenesulfonic acid (TNBS) in all groups, aside from the Sham group.The experimental groups consisted of: the Sham group that received only normal saline; the Mag-50, Mag-100 and Mag-200 groups, which received 50, 100 and 200 mg/kg per day of Magliasa, respectively; the control group, which received vehicle water orally; the infliximab group, which received infliximab (5 mg/kg per day, subcutaneously); and the Dexa group, which received dexamethasone (1 mg/kg per day, orally). After completing the treatment period (2 wk), the rats were sacrificed, the colon was removed, its macroscopic and microscopic changes were recorded, and tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1b), total antioxidant capacity, myeloperoxidase (MPO), and lipid peroxidation (LPO) were assessed in colon homogenate.RESULTS: The mean value of total glucosinolates in one gram of Magliasa was 19 ± 1 μmol. The mean value of the total phenolic content was 293.8 ± 17.6 mg gallic acid equivalents per 100 gram of Magliasa. Macroscopic scores were significantly decreased in Mag-100 (1.80 ± 0.58, P = 0.019) and Mag-200 (1.20 ± 0.20, P = 0.001) compared to the control group (3.40 ± 0.24), although some inflammation and hyperemia were evident. Treatment of rats by dexamethasone (0.33 ± 0.21, P < 0.001) and infliximab (0.83 ± 0.31, P < 0.001) remarkably attenuated scores where mild hyperemia was observed macroscopically. In comparison to the control group (4.00 ± 0.32), only Mag-200 (1.60 ± 0.40) showed a significant decrease in colonic histopathological scores (P = 0.005). Minimal mucosal inflammation was observed in the Dexa group (0.67 ± 0.21, P < 0.001). The levels of TNF-α, IL-1b and MPO were significantly lower in all groups compared to the controls (P < 0.05). A significant decrease in LPO was seen in the Mag-200 (3.27 ± 0.77, P = 0.01) and Dexa (3.44 ± 0.22, P = 0.011) groups in comparison to the control group (6.43 ± 0.61). Only dexamethasone caused a significant increase in antioxidant power in comparison to the control group (346.73 ± 9.9 vs 228.33 ± 2.75, P < 0.001). Infliximab and different doses of Magliasa did not show any remarkable increase in antioxidant capacity (P > 0.05). The effect of Magliasa in all of mentioned parameters, except antioxidant capacity, was dose dependent.CONCLUSION: The effects of Magliasa in TNBS-induced colitis are encouraging and warrant clinical trials for further confirmation. | Roja Rahimi Amir Baghaei Maryam Baeeri Gholamreza Amin Mohammad Reza Shams-Ardekani Mahnaz Khanavi Mohammad Abdollahi | 2013 | World Journal of Gastroenterology2013，19，12： | 2 |

| 17 | COVID-19 and liver injury:Pathophysiology,risk factors,outcome and management in special populations显示文摘The coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus-2 is an ongoing health concern.In addition to affecting the respiratory system,COVID-19 can potentially damage other systems in the body,leading to extra-pulmonary manifestations.Hepatic manifestations are among the common consequences of COVID-19.Although the precise mechanism of liver injury is still questionable,several mechanisms have been hypothesized,including direct viral effect,cytokine storm,hypoxic-ischemic injury,hypoxiareperfusion injury,ferroptosis,and hepatotoxic medications.Risk factors of COVID-19-induced liver injury include severe COVID-19 infection,male gender,advanced age,obesity,and underlying diseases.The presentations of liver involvement comprise abnormalities in liver enzymes and radiologic findings,which can be utilized to predict the prognosis.Increased gamma-glutamyltransferase,aspartate aminotransferase,and alanine aminotransferase levels with hypoalbuminemia can indicate severe liver injury and anticipate the need for intensive care units’hospitalization.In imaging,a lower liver-to-spleen ratio and liver computed tomography attenuation may indicate a more severe illness.Furthermore,chronic liver disease patients are at a higher risk for severe disease and death from COVID-19.Nonalcoholic fatty liver disease had the highest risk of advanced COVID-19 disease and death,followed by metabolic-associated fatty liver disease and cirrhosis.In addition to COVID-19-induced liver injury,the pandemic has also altered the epidemiology and pattern of some hepatic diseases,such as alcoholic liver disease and hepatitis B.Therefore,it warrants special vigilance and awareness by healthcare professionals to screen and treat COVID-19-associated liver injury accordingly. | Romina Roshanshad Amirhossein Roshanshad Reza Fereidooni Mahnaz Hosseini-Bensenjan | 2023 | World Journal of Hepatology2023，15，4： | 2 |

| 19 | Phytochemistry and larvicidal activity of Eucalyptus camaldulensis against malaria vector,Anopheles stephensi显示文摘Objective:To determine phytochemistry and larvicidal activity of Eucalyptus eamaldulensis against Anopheles stephensi.Methods:The chemical compositions of the leaf essential oils were analyzed using gas chromatography/mass spectrometry(GC/MS).The larvicidal activity of essential oils and extract of leaf were tested against 4th instar larvae of laboratory-reared Anopheles stephensi.Results:GC/MS analyses identified the presence of 28 compounds corresponding to 99.60%of the total oil.The main constituents in the leaf essential oil were 1,8-cineole(69.46%),γ-Terpinene(15.10%),α-Pinene(5.47%) and Globulol(2%).The leaf extract and volatile oil exerted significant larvicidal activity with LC50 values of 89.85 and 397.75 ppm,respectively.Clear dose-response relationships were established with the highest dose of 320 ppm essential oil extract resulted almost 100%mortality in the population.Conclusions:The larvicidal properties suggest that the essential oil of plant is a potential source of valuable larvicidal compounds against malaria vector and can be used as an alternative to synthetic insecticides. | Sedaghat Mohamad Medhi Sanei Dehkordi Ali Reza Khnavi Mahnaz Abai Mohammad Reza Hadjiakhoondi Abbas Mohtarami Fatemeh Vatandoost Hassan | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，11： | 2 |
| 20 | Using shape contexts method for registration of contra lateral breasts in thermal images显示文摘AIM: To achieve symmetric boundaries for left and right breasts boundaries in thermal images by registration. METHODS: The proposed method for registration consists of two steps. In the first step, shape context, an approach as presented by Belongie and Malik was applied for registration of two breast boundaries. The shape context is an approach to measure shape similarity. Two sets of finite sample points from shape contours of two breasts are then presented. Consequently, the correspondences between the two shapes are found. By finding correspondences, the sample point which has the most similar shape context is obtained. RESULTS: In this study, a line up transformation which maps one shape onto the other has been estimated in order to complete shape. The used of a thin plate spline permitted good estimation of a plane transformation which has capability to map unselective points from one shape onto the other. The obtained aligningtransformation of boundaries points has been applied successfully to map the two breasts interior points. Some of advantages for using shape context method in this work are as follows:(1) no special land marks or key points are needed;(2) it is tolerant to all common shape deformation; and(3) although it is uncomplicated and straightforward to use, it gives remarkably powerful descriptor for point sets significantly upgrading point set registration. Results are very promising. The proposed algorithm was implemented for 32 cases. Boundary registration is done perfectly for 28 cases.CONCLUSION: We used shape contexts method that is simple and easy to implement to achieve symmetric boundaries for left and right breasts boundaries in thermal images. | Mahnaz Etehadtavakol Eddie Yin-Kwee Ng Niloofar Gheissari | 2014 | World Journal of Clinical Oncology2014，5，5： | 2 |
