| 1 | Preconcentration of rare earth elements from Iranian monazite ore by spiral separator using multi-response optimization method显示文摘The present work dealt with the preconcentration of rare earth elements in Saghand ore(Yazd province,Iran)which was achieved by Humphrey spiral using orthogonal optimization method after scrubbing the sample at 45%solid pulp density for 30 min.The pulp was diluted and was fed to a Humphrey spiral for upgrading.The process parameters considered were feed size,feed solids and feed rate,and Taguchi’s L9(34)orthogonal array(OA)was selected for optimization of the process.The results show that the feed rate and feed size were more significant than the other operation parameters of the process.It was also found that under optimal conditions,the concentrate grade of rare earth elements increased from2860 10 6to 6050 10 6and recovery reached to 58%. | Khanchi Ali Reza Sedighi Hassan Ansar Sheida Fasihi Javad | 2014 | International Journal of Mining Science and Technology2014，24，1： | 5 |
| 2 | Prediction of meteorological drought in arid and semi-arid regions using PDSI and SDSM: a case study in Fars Province, Iran显示文摘Drought is one of the most significant environmental disasters,especially in arid and semi-arid regions.Drought indices as a tool for management practices seeking to deal with the drought phenomenon are widely used around the world.One of these indicators is the Palmer drought severity index(PDSI),which is used in many parts of the world to assess the drought situation and continuation.In this study,the drought state of Fars Province in Iran was evaluated by using the PDSI over 1995-2014 according to meteorological data from six weather stations in the province.A statistical downscaling model(SDSM)was used to apply the output results of the general circulation model in Fars Province.To implement data processing and prediction of climate data,a statistical period 1995-2014 was considered as the monitoring period,and a statistical period 2019-2048 was for the prediction period.The results revealed that there is a good agreement between the simulated precipitation(R2>0.63;R2,determination coefficient;MAE<0.52;MAE,mean absolute error;RMSE<0.56;RMSE,Root Mean Squared Error)and temperature(R2>0.95,MAE<1.74,and RMSE<1.78)with the observed data from the stations.The results of the drought monitoring model presented that dry periods would increase over the next three decades as compared to the historical data.The studies showed the highest drought in the meteorological stations Abadeh and Lar during the prediction period under two future scenarios representative concentration pathways(RCP4.5 and RCP8.5).According to the results of the validation periods and efficiency criteria,we suggest that the SDSM is a proper tool for predicting drought in arid and semi-arid regions. | Sheida DEHGHAN Nasrin SALEHNIA Nasrin SAYARI Bahram BAKHTIARI | 2020 | Journal of Arid Land2020，12，2： | 4 |
| 3 | Microbiome-liver crosstalk:A multihit therapeutic target for liver disease显示文摘Liver disease has become a leading cause of death,particularly in the West,where it is attributed to more than two million deaths annually.The correlation between gut microbiota and liver disease is still not fully understood.However,it is well known that gut dysbiosis accompanied by a leaky gut causes an increase in lipopolysaccharides in circulation,which in turn evoke massive hepatic inflammation promoting liver cirrhosis.Microbial dysbiosis also leads to poor bile acid metabolism and low short-chain fatty acids,all of which exacerbate the inflammatory response of liver cells.Gut microbial homeostasis is maintained through intricate processes that ensure that commensal microbes adapt to the low oxygen potential of the gut and that they rapidly occupy all the intestinal niches,thus outcompeting any potential pathogens for available nutrients.The crosstalk between the gut microbiota and its metabolites also guarantee an intact gut barrier.These processes that protect against destabilization of gut microbes by potential entry of pathogenic bacteria are collectively called colonization resistance and are equally essential for liver health.In this review,we shall investigate how the mechanisms of colonization resistance influence the liver in health and disease and the microbial-liver crosstalk potential as therapeutic target areas. | Jorum Kirundi Sheida Moghadamrad Camilla Urbaniak | 2023 | World Journal of Gastroenterology2023，29，11： | 1 |

| 9 | Protective efficacy of dark chocolate in letrozole-induced ovary toxicity model rats: hormonal, biochemical, and histopathological investigation显示文摘OBJECTIVE: To assess the protective effect of dark chocolate(DC) on the letrozole-induced rat model of polycystic ovary syndrome(PCOS). METHODS: In this experimental study, 32 female Wistar rats, weighing(200 ± 20) g, were randomly categorized into 4 groups including control, letrozole(1 mg·kg-1·d-1), metformin(500 mg·kg-1·d-1) along with letrozole, and DC(500 mg·kg-1·d-1) along with letrozole for 28 d by oral gavage. Twenty-four hours after the last supplementation, direct blood sampling was taken from the heart to obtain blood serum for evaluation of sex hormones and gonadotropins, oxidative parameters, inflammatory cytokines, and ovarian tissue was examined for histology. RESULTS: The DC treatment significantly improved PCOS signs, as demonstrated by the significant restoration of ovarian morphology and physiological functions as compared with the letrozole group. DC treatment also decreased ovarian interleukin-1β and tumor necrosis factor-α levels and improved total oxidative/antioxidative status as compared with the letrozole group. CONCLUSIONS: Treating the animals with DC could alleviate the PCOS symptoms and reduced the toxic effects of letrozole in the ovary. This effect may mediate through antioxidant and antiinflammatory properties. | Naser Mirazi Sheida Hesami Alireza Nourian Abdolkarim Hosseini | 2022 | Journal of Traditional Chinese Medicine2022，42，5： | 0 |
