| 1 | Influence of the roughness and shape of quartz particles on their flotation kinetics显示文摘Surface roughness and shape play an important role on the behavior of particles in various processes such as flotation. In this re-search, the influence of different grinding methods on the surface roughness and shape characteristics of quartz particles as well as the effect of these parameters on the flotation of the particles was investigated. The surface roughness of the particles was determined by measuring their specific surface area via the gas adsorption method. The shape characteristics of the particles were measured and calculated by images obtained by scanning electron microscopy via an image analysis system. The flotation kinetics was determined using a laboratory flotation cell. The results showed that the particles of rod mill products have higher roughness and elongation ratio and lower roundness than the parti-cles of ball mill products. The flotation kinetics constant of the particles increased with their surface roughness increasing. Particles with higher elongation and lower roundness indicated higher floatability. In addition, the influence of the surface roughness on the flotation kinet-ics was greater than that of shape parameters. | Mehdi Rahimi Fahimeh Dehghani Bahram Rezai Mohammad Reza Aslani | 2012 | International Journal of Minerals,Metallurgy and Materials2012,19,4: | 8 |
| 2 | Are body mass index and waist circumference significant predictors of diabetes and prediabetes risk: Results from a population based cohort study显示文摘AIM To determine the predictive role of body mass index(BMI) and waist circumference(WC) for diabetes and prediabetes risk in future in total sample as well as in men and women separately. METHODS In a population based cohort study, 1765 with mean ± SD age: 42.32 ± 6.18 healthy participants were followed up from 2003 till 2013(n = 960). Anthropometric and biochemical measures of participants were evaluated regularly during the follow up period. BMI and WC measures at baseline and diabetes and prediabetes status of participants at 2013 were determined. Multivariable logistic regression analysis was used for determining the risk of diabetes and prediabetes considering important potential confounding variables. Receiver operatingcharacteristic curve analysis was conducted to determine the best cut of values of BMI and WC for diabetes and prediabetes. RESULTS At 2013, among participants who had complete data, 45 and 307 people were diabetic and prediabetic, respectively. In final fully adjusted model, BMI value was a significant predictor of diabetes(RR = 1.39, 95%CI: 1.06-1.82 and AUC = 0.68, 95%CI: 0.59-0.75; P < 0.001) however not a significant risk factor for prediabetes. Also, WC was a significant predictor for diabetes(RR = 1.2, 95%CI: 1.05-1.38 and AUC = 0.67, 95%CI: 0.6-0.75) but not significant risk factor for prediabetes. Similar results were observed in both genders.CONCLUSION General and abdominal obesity are significant risk factors for diabetes in future. | Fahimeh Haghighatdoost Masoud Amini Awat Feizi Bijan Iraj | 2017 | World Journal of Diabetes2017,8,7: | 4 |

| 4 | Dynamics of a neuron exposed to integer-and fractional-order discontinuous external magnetic flux显示文摘We propose a modified Fitzhugh-Nagumo neuron(MFNN) model. Based on this model, an integerorder MFNN system(case A) and a fractional-order MFNN system(case B) were investigated. In the presence of electromagnetic induction and radiation, memductance and induction can show a variety of distributions. Fractionalorder magnetic flux can then be considered. Indeed, a fractional-order setting can be acceptable for non-uniform diffusion. In the case of an MFNN system with integer-order discontinuous magnetic flux, the system has chaotic and non-chaotic attractors. Dynamical analysis of the system shows the birth and death of period doubling, which is a sign of antimonotonicity. Such a behavior has not been studied previously in the dynamics of neurons. In an MFNN system with fractional-order discontinuous magnetic flux, different attractors such as chaotic and periodic attractors can be observed. However, there is no sign of antimonotonicity. | Karthikeyan RAJAGOPAL Fahimeh NAZARIMEHR Anitha KARTHIKEYAN Ahmed ALSAEDI Tasawar HAYAT Viet-Thanh PHAM | 2019 | Frontiers of Information Technology & Electronic Engineering2019,20,4: | 2 |

| 6 | Different metabolic/obesity phenotypes are differentially associated with development of prediabetes in adults: Results from a 14-year cohort study显示文摘BACKGROUND The risk of developing prediabetes based on the metabolic/obesity phenotypes has been poorly investigated. AIM To examine the association of baseline metabolic/obesity phenotypes and their changes over time with the risk of prediabetes development. METHODS In a population-based cohort study, 1741 adults (aged > 19 years) with normal blood glucose were followed for 14 years. Anthropometric and biochemical measures were evaluated regularly during the follow-up period. According to body mass index and metabolic health status, participants were categorized into four groups: Metabolically healthy normal weight (MHNW), metabolically healthy obese (MHO), metabolically unhealthy normal weight (MUNW) and metabolically unhealthy obese (MUO). Multivariable Cox regression analysis was used to measure the risk of prediabetes according to the baseline metabolic/obesity phenotype and their changes during the follow-up. RESULTS In the whole population with a mean (95CCI for mean) follow up duration of 12.7 years (12.6-12.9), all three MUNW, MHO, MUO groups were at higher risk for developing prediabetes compared to the MHNW group (P = 0.022). The MUNW group had the highest risk for developing prediabetes (hazard ratio (HR): 3.84, 95%CI: 1.20, 12.27). In stratified analysis by sex, no significant association was found in men, while women in the MUNW group were at the greatest risk for prediabetes (HR: 6.74, 95%CI: 1.53, 29.66). Transforming from each phenotype to MHNW or MHO was not related to the risk of prediabetes development, whereas transforming from each phenotype to MUO was associated with an increased risk of prediabetes (HR > 1;P < 0.05). CONCLUSION Our findings indicate that MHO is not a high risk, unless it transforms into MUO over time. However, people in the MUNW group have the greatest risk for developing prediabetes, and therefore, they should be screened and treated. | Fahimeh Haghighatdoost Masoud Amini Ashraf Aminorroaya Majid Abyar Awat Feizi | 2019 | World Journal of Diabetes2019,10,6: | 2 |

| 13 | 误诊为黑色素瘤的视网膜色素上皮细胞来源的腺癌1例(英文)显示文摘视网膜色素上皮细胞(RPE)形成的肿瘤较少,常见肿瘤类型有黑色素瘤,少见类型包括RPE形成的腺癌,这两种肿瘤在临床和病理特点上都有所不同。本文报道1例60岁的男性患者,因为进展性视力丧失,眼科诊断为黑色素瘤而行右眼摘除术。病理学检查发现后极部接近视神经处可见实性、界限清楚的病灶。组织学检查见构成肿瘤的细胞,具有大的多形、浓染的核,核仁突出,色素极少;肿瘤细胞多呈乳头状排列。为和黑色素瘤进行区别,进一步行免疫组织化学染色。结果显示上皮膜抗原(EMA)为强阳性,HMB45阴性,支持RPE来源的腺癌诊断。系统检查排除了转移癌。总之,虽然RPE来源的腺癌非常少见,但必须清楚它与脉络膜黑色素瘤在诊断上的异同点。 | Fahimeh Asadi-Amoli Mohammad Taher Rajabi Hedyeh Moradi Mohammad Riazi-Esfahani | 2007 | 国际眼科杂志2007,7,5: | 1 |
| 14 | Evaluation of imatinib mesylate(Gleevec) on KAI1/CD82 gene expression in breast cancer MCF-7 cells using quantitative real-time PCR显示文摘Objective: To evaluate the effect of imatinib mesylate on cell viability, anti cancer effect through modulation of KAI1/CD82 gene expression in breast cancer MCF-7 cell line.Methods: The effects of imatinib mesylate on cell viability in MCF-7 cell line were assessed using MTT assay and IC_(50) value was determined. GAPDH and KAI1/CD82 were selected as reference and target genes, respectively. Quantitative real time PCR technique was applied for investigation of KAI1/CD82 gene expression in human breast cancer MCF-7 cells. Subsequently, the quantity of KAI1 compared to GAPDH gene expressions were analyzed using the formula; 2^(-DDCt).Results: Imatinib was showed to have a dose-dependent inhibitory effect on the viability of MCF-7 cells. CD82/GAPDH gene expression ratios were 1.322 ± 0.030(P > 0.05),2.052 ± 0.200(P < 0.05), 2.151 ± 0.270(P < 0.05) for 10, 20 and 40 mmol/L of imatinib concentrations.Conclusions: Based on the present data, imatinib mesylate might modulate metastasis by up-regulating KAI1/CD82 gene expression in human breast MCF-7 cancer cell line. | Seyed Ataollah Sadat Shandiz Marjan Khosravani Sepideh Mohammadi Hassan Noorbazargan Amir Mirzaie Davoud Nouri Inanlou Mojgan Dalirsaber Jalali Hamidreza Jouzaghkar Fahimeh Baghbani-Arani Behta Keshavarz-Pakseresht | 2016 | Asian Pacific Journal of Tropical Biomedicine2016,6,2: | 1 |
