1Settling characteristics of ultrafine iron ore slimes显示文摘The slurry settling characteristics are the most important to design a thickener in process industries. In this work, the iron ore slurry from the screw classifier overflow was used for the settling study. It was observed that the original slurry exhibited a low settling velocity and a turbid supernatant during the settling process. Commercial flocculating agents with anionic, cationic, and nonionic characters were used to improve the settling behavior of suspensions, which were added into the slurry at different ranges of slurry pH values, respectively. The settling results show that the use of flocculants increase the settling rate by several times. Compared with the cationic and non-ionic flocculants, the anionic flocculant is more effective in enhancing the slurry settling rate. The small dose of the anionic flocculant is found to be more effective, but the other flocculants are less effective even at higher dosages. The simulation of an industrial thickener was carried out based on the laboratory settling data, and the appropriate design and selection parameters of the industrial thickener were estimated.Chinthapudi Eswaraiah Surendra Kumar Biswal Barada Kanta Mishra 2012International Journal of Minerals,Metallurgy and Materials2012,19,2:28
2Non-invasive determination of hepatic steatosis by acoustic structure quantification from ultrasound echo amplitude显示文摘AIM:To use leptin-deficient(ob/ob) mice with demonstrated differences in steatosis levels to test a new diagnostic method using the acoustical structure quantification(ASQ) mode and the associated analytical parameter,'focal disturbance ratio'(FD-ratio).METHODS:Nine ob/ob mice,at 5,8,and 12 wk of age(n = 3 in each age group),were used as models for hepatic steatosis.Echo signals obtained from ultrasonography in the mice were analyzed by ASQ,which uses a statistical analysis of echo amplitude to estimate inhomogeneity in the diagnostic region.FD-ratio,as calculated from this analysis,was the focus of the present study.FD-ratio and fat droplet areas and sizes were compared between age groups.RESULTS:No fibrosis or inflammation was observed in any of the groups.The fat droplet area significantly(P < 0.01) increased with age from 1.25% ± 0.28% at 5 wk to 31.07% ± 0.48% at 8 wk to 51.69% ± 3.19% at 12 wk.The median fat droplet size also significantly(P < 0.01) increased with age,from 1.33(0.55-10.52) m at 5 wk,2.82(0.61-44.13) m at 8 wk and 6.34(0.66-81.83) m at 12 wk.The mean FD-ratio was 0.42 ± 0.11 at 5 wk,0.11 ± 0.05 at 8 wk,and 0.03 ± 0.02 at 12 wk.The FD-ratio was significantly lower at 12 wk than at 5 wk and 8 wk(P < 0.01).A significant negative correlation was observed between the FD-ratio and either the fat droplet area(r =-0.7211,P = 0.0017) or fat droplet size(r =-0.9811,P = 0.0052).CONCLUSION:This tool for statistical analysis of signals from ultrasonography using the FD-ratio can be used to accurately quantify fat in vivo in an animal model of hepatic steatosis,and may serve as a quantitative biomarker of hepatic steatosis.Hidekatsu Kuroda Keisuke Kakisaka Naohisa Kamiyama Takayoshi Oikawa Mio Onodera Kei Sawara Kanta Oikawa Ryujin Endo Yasuhiro Takikawa Kazuyuki Suzuki 2012World Journal of Gastroenterology2012,18,29:15
3Computational Identification of Sweet Wormwood (Artemisia annua) microRNA and Their mRNA Targets显示文摘Despite its efficacy against malaria, the relatively low yield (0.01%-0.8%) of artemisinin in Artemisia annua is a serious limitation to the commercialization of the drug. A better understanding of the biosynthetic pathway of artemisinin and its regulation by both exogenous and endogenous factors is essential to improve artemisinin yield. Increasing evidence has shown that microRNAs (miRNAs) play multiple roles in various biological processes. In this study, we used previously known miRNAs from Arabidopsis and rice against expressed sequence tag (EST) database of A. annua to search for potential miRNAs and their targets in A. annua. A total of six potential miRNAs were predicted, which belong to the miR414 and miR1310 families. Furthermore, eight potential target genes were identified in this species. Among them, seven genes encode proteins that play important roles in ar- temisinin biosynthesis, including HMG-CoA reductase (HMGR), amorpha-4,11-diene synthase (ADS), farnesyl pyrophosphate synthase (FPS) and cytochrome P450. In addition, a gene coding for putative AINTEGUMENTA, which is involved in signal transduction and development, was also predicted as one of the targets. This is the first in silico study to indicate that miRNAs target genes encoding enzymes involved in artemisinin biosynthesis, which may help to understand the miRNA-mediated regulation of artemisinin biosynthesis in A. annua.Alok Pani Rajani Kanta Mahapatra Niranjan Behera Pradeep Kumar Naik 2011Genomics, Proteomics & Bioinformatics2011,9,6:7

5Transcatheter arterial chemoembolization with a fine-powder formulation of cisplatin for hepatocellular carcinoma显示文摘AIM:To evaluate the efficacy of transcatheter arterial chemoembolization(TACE) using a suspension of a fine-powder formulation of cisplatin(DDPH) for hepatocellular carcinoma(HCC).METHODS:The study population was comprised of 164 patients who were treated by TACE alone.Of these patients,76 underwent TACE using a suspension of DDPH in lipiodol(LPD)(DDPH group),and the remaining 88 underwent TACE with an emulsion of doxorubicin(ADM) with LPD(ADM group).We compared the DDPH group with the ADM group in terms of the objective early response rate,progression free survival(PFS) and overall survival(OS).RESULTS:The objective early response rate in the DDPH group was significantly higher than that in the ADM group(54% vs 24%,P < 0.001).The PFS rate in the DDPH group was also significantly higher than that in the ADM group(P < 0.001).Moreover,the OS in the DDPH group was significantly longer than that in the ADM group(P = 0.002).Although the incidence rate of nausea or vomiting in the DDPH group was higher than that in the ADM group,the ADM group showed a higher incidence rate of the adverse events of hepatic arterial damage and leucopenia.No other serious complications were observed in either group.CONCLUSION:We conclude that TACE using a suspension of DDPH in LPD could be a useful treatment for HCC.Kazuhiro Kasai Akira Ushio Kei Sawara Yasuhiro Miyamoto Yukiho Kasai Kanta Oikawa Hidekatsu Kuroda Yasuhiro Takikawa Kazuyuki Suzuki 2010World Journal of Gastroenterology2010,16,27:6
6Innate and adaptive T cells in influenza disease显示文摘流行性感冒是一个主要全球健康问题,引起呼吸的道的感染,经常导致急性肺病,威胁生活的复杂并发症甚至死亡。在最后七十年,种痘策略被利用了保护人免受流行性感冒的复杂并发症的伤害,特别在严重疾病的高风险的组。当当前的种痘政体得到紧张特定的抗体回答时,他们没能产生对季节、流行、鸟的病毒跨保护。而且,设计产生流行性感冒特定的 T 房间回答的疫苗还有待于被优化。在自然感染期间,在适应有免疫力的回答(T 细胞和生产抗体的 B 细胞) 完成病毒的清理和宿主恢复以前,病毒的复制被天生的免疫开始控制。适应 T 和 B 房间维持免疫学的记忆并且对随后的感染向保护提供相关流行性感冒病毒。最近的研究也在控制流行性感冒并且连接天生、适应的有免疫力的机制使天生的 T 房间(MAIT 房间, gd T 房间,和 NKT 房间) 的角色清楚些,因此为种痘策略使他们成为吸引人的目标。我们象适应 CD8 + 和 CD4 + T 房间一样在流行性感冒特定的天生的 MAIT 和 gd T 房间上总结当前的知识,并且讨论这些回答怎么能被新奇疫苗的策略利用对不同流行性感冒紧张和子类型得到跨 protective 免疫。Simone Nfissing Sneha Sant Marios Koutsakos Kanta Subbarao Thi H.O.

7Liver cirrhosis induced by long-term administration of a daily low dose of amiodarone: A case report显示文摘The anti-arrhythmic agent amiodarone (AD) is associated with numerous adverse effects, but serious liver disease is rare. The improved safety of administration of daily low doses of AD has already been established and this regimen is used for long-term medication. Nevertheless,asymptomatic continuous liver injury by AD may increase the risk of step-wise progression of non-alcoholic fatty liver disease. We present an autopsy case of AD-induced liver cirrhosis in a patient who had been treated with a low dose of AD (200 mg/d) daily for 84 mo. The patient was a 85-year-old male with a history of ischemic heart disease.Seven years after initiation of treatment with AD, he was admitted with cardiac congestion. The total dose of AD was 528 g. Mild elevation of serum aminotransferase and hepatomegaly were present. Liver biopsy specimens revealed cirrhosis, and under electron microscopy numerous lysosomes with electron-dense, whorled, lamellar inclusions characteristic of a secondary phospholipidosis were observed. Initially, withdrawal of AD led to a slight improvement of serum aminotransferase levels, but unfortunately his general condition deteriorated and he died from complications of pneumonia and renal failure.Long-term administration of daily low doses of AD carries the risk of progression to irreversible liver injury. Therefore,periodic examination of liver function and/or liver biopsy is required for the management of patients receiving long-term treatment with AD.Hiroki Oikawa Chihaya Maesawa Ryo Sato Kanta Oikawa Hiroyuki Yamada Seizo Oriso Sadahide Ono Akiko Yashima-Abo Koji Kotani Kazuyuki Suzuki Tomoyuki Masuda 2005World Journal of Gastroenterology2005,11,34:4
8Adaptive design of an X-ray magnetic circular dichroism spectroscopy experiment with Gaussian process modelling显示文摘Spectroscopy is a widely used experimental technique,and enhancing its efficiency can have a strong impact on materials research.We propose an adaptive design for spectroscopy experiments that uses a machine learning technique to improve efficiency.We examined X-ray magnetic circular dichroism(XMCD)spectroscopy for the applicability of a machine learning technique to spectroscopy.An XMCD spectrum was predicted by Gaussian process modelling with learning of an experimental spectrum using a limited number of observed data points.Adaptive sampling of data points with maximum variance of the predicted spectrum successfully reduced the total data points for the evaluation of magnetic moments while providing the required accuracy.The present method reduces the time and cost for XMCD spectroscopy and has potential applicability to various spectroscopies.Tetsuro Ueno Hideitsu Hino Ai Hashimoto Yasuo Takeichi Masahiro Sawada Kanta Ono 2018npj Computational Materials2018,,1:4

10Automated crystal structure analysis based on blackbox optimisation显示文摘In the present study,we show that time-consuming manual tuning of parameters in the Rietveld method,one of the most frequently used crystal structure analysis methods in materials science,can be automated by considering the entire trial-and-error process as a blackbox optimisation problem.The automation is successfully achieved using Bayesian optimisation,which outperforms both a human expert and an expert-system type automation despite the absence of expertise.This approach stabilises the analysis quality by eliminating human-origin variance and bias,and can be applied to various analysis methods in other areas which also suffer from similar tiresome and unsystematic manual tuning of extrinsic parameters and human-origin variance and bias.Yoshihiko Ozaki Yuta Suzuki Takafumi Hawai Kotaro Saito Masaki Onishi Kanta Ono 2020npj Computational Materials2020,,1:3
11缅甸坡鹿(Cervus eldi thamin)雌性群等级序位的初步研究显示文摘本文对11只雌性缅甸坡鹿合群后等级序位建立过程进行了观察,用全部事件取样法(Alloccurrence sampling)对坡鹿的14种社会行为进行了记录,在观察期内记录到1145个社会行为中有962次(84%)是侵犯行为,183次(16%)友好行为。根据侵犯指数和优势指数排列了各个体的优势等级序位,经用兰道氏(Landau's)指数测定,坡鹿群的优势等级序位是很强的线性等级序位。坡鹿在合群后,通过激烈的争斗建立群内的优势等级序位;然后以较温和的威胁姿态来维持已建立的等级序位。新的入侵者进入已建立等级序位的鹿群会触发起重新争夺序位的激烈争斗。徐宏发 Kanta Kumari J.S.Lwanga 1990兽类学报1990,10,2:3
12Geochemical characteristics of Holocene sediments from Chuadanga district, Bangladesh: Implications for weathering, climate, redox conditions, provenance and tectonic setting显示文摘The present research deals with the geochemical characteristics of the Holocene sediments from Alamdanga area, Chuadanga district, Bangladesh. Main goals of the study are to delineate source rock characteristics, degree of chemical weathering and sorting processes and behavior of redox conditions during deposition of the sediments. Geochemical characteristics of the sediments show comparatively a wide variation in accordance with stratigraphy in their major element contents(e.g. Si O2 69.46–82.13, Al2O3 2.28–8.88 in wt%), reflecting the distinctive provenance and in part an unstable period in terms of tectonic activity. Geochemical classification of the sediments shows mostly sub-arkose with few sub-litharenites. Some major and trace elements display comprehensible correlation with Al2O3 confirming their possible hydraulic fractionation. The chemical index of alteration(CIA*), W* index, index of compositional variability(ICV), plagioclase index of alteration(PIA*) values and the ratio of Si O2/Al2O3, suggest low degrees of chemical weathering in the source areas as well as immature to moderately mature the sediments. The sediments suggest semi-arid climatic trends within oxic deltaic depositional conditions during the Holocene, at 3–12 ka. Whole rock geochemistry and discrimination diagrams demonstrate the continental signature derivatives, which might have been derived from the felsic to intermediate igneous rocks(granitic plutonic rocks) as well as from quartzose sedimentary/metamorphic provenance. These typical sources are present in a vast region of the Himalayan belt and catchment areas of Ganges. The tectonic setting of the sediments demarcates typically passive margin with slightly continental arc system.Ismail Hossain Krisna Kanta Roy Pradip Kumar Biswas Mahbubul Alam Md.

15Characterization of dolochar wastes generated by the sponge iron industry显示文摘Solid wastes generated by the metallurgical industry contribute significantly towards the enhancement of environmental pollution. The handling, utilization, and safe disposal of these solid wastes are major concerns for the world. Dolochar is such a solid waste generated by the sponge iron industry. Investigations were carried out on the physical, mineralogical, and chemical characteristics for the efficient utilization of dolochar. The detailed studies on physico-chemical properties and petrography were carried out by optical microscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM). Characterization studies revealed that the dolochar consists of quartz (free as well as locked), free lime, Fe particles, and Ca or Mg and/or Ca+Mg+Fe oxide phases. The washability data of-300 μm dolochar samples indicated that clean coal with 41wt% ash at 18% yield can be produced from dolochar with 78wt% ash. The studies further suggested that the liberation of the dolochar is hard to achieve for clear separation. The dolochar is observed to have high ash fusion temperature and the unburned carbon can be best utilized for power generation.Ranjan Kumar Dwari Danda Srinivas Rao Akhila Kumar Swar Palli Sita Ram Reddy Barada Kanta Mishra 2012International Journal of Minerals,Metallurgy and Materials2012,19,11:2
