Background Ursodeoxycholic acid(UDCA),statins,and ezetimibe(EZE)have demonstrated beneficial effects against nonalcoholic fatty liver disease(NAFLD).We investigated the efficacy of the combination of UDCA and the mix of rosuvastatin(RSV)/EZE in the treatment of *** NAFLD mouse models were developed by injecting thioacetamide,fasting,and high-carbohydrate refeeding,highfat diet,and choline-deficient L-amino acid-defined high-fat diet(CDAHFD).Low-dose UDCA(L-UDCA;15 mg/kg)or highdose UDCA(H-UDCA;30 mg/kg)was administered with RSV/*** also employed an in vitro model of NAFLD developed using palmitic acid-treated Hepa1c1c7 *** Co-administration of RSV/EZE with UDCA significantly decreased the collagen accumulation,serum alanine aminotransferase(ALT)levels,and mRNA levels of fibrosis-related markers than those observed in the vehicle group in thioacetamide-treated mice(all P<0.01).In addition,in the group fasted and refed with a high-carbohydrate diet,UDCA/RSV/EZE treatment decreased the number of apoptotic cells and serum ALT levels compared with those observed in the vehicle group(all P<0.05).Subsequently,H-UDCA/RSV/EZE treatment decreased the number of ballooned hepatocytes and stearoyl-CoA desaturase 1(SCD-1)mRNA levels(P=0.027)in the liver of high-fat diet-fed mice compared with those observed in the vehicle *** the CDAHFD-fed mouse model,UDCA/RSV/EZE significantly attenuated collagen accumulation and fibrosis-related markers compared to those observed in the vehicle group(all P<0.05).In addition,UDCA/RSV/EZE treatment significantly restored cell survival and decreased the protein levels of apoptosis-related markers compared to RSV/EZE treatment in palmitic acid-treated Hepa1c1c7 cells(all P<0.05).Conclusion Combination therapy involving UDCA and RSV/EZE may be a novel strategy for potent inhibition of NAFLD progression.

Evaluation of the relationship between two different methods for enumeration fecal indicator bacteria: Colony-forming unit and most probable number

引用

Journal of Environmental Sciences 2010年第6期22卷 846-850页

Most probable number （MPN） and colony-forming unit （CFU） estimates of fecal indicator bacteria （FIB） concentration are common measures of water quality in aquatic environments. Thus, FIB intensively monitored in Yeongsan Watershed in an attempt to compare two different methods and to develop a statistical model to convert from CFU to MPN estimates or vice versa. As a result, the significant difference was found in the MPN and CFU estimates. The enumerated Escherichia coli concentrations in MPN are greater than those in CFU, except for the measurement in winter. Especially in fall, E. coli concentrations in MPN are one order of magnitude greater than that in CFU. Contrarily, enterococci bacteria in MPN are lower than those in CFU. However, in general, a strongly positive relationship are found between MPN and CFU estimates. Therefore, the statistical models were developed, and showed the reasonable converting FIB concentrations from CFU estimates to MPN estimates. We expect this study will provide preliminary information towards future research on whether different analysis methods may result in different water quality standard violation frequencies for the same water sample.

Efective Object Identification and Association by Varying Coverage Through RFID Power Control

引用

Journal of Computer Science & Technology 2014年第1期29卷 4-20页

作者： Shung Han cho kyung Hoon Kim Sangjin Hong IEEE System LSI Business Samsung Electronics Department of Electrical and Computer Engineering Stony Brook University

This paper presents an effective power scheduling strategy for energy efficient multiple objects identification and association. The proposed method can be utilized in many heterogeneous surveillance systems with visual sensors and RFID （radio-frequency identification） readers where energy efficiency as well as association rate are critical Multiple objects positions and trajectory estimates are used to decide the power level of RFID readers. Several key parameters including the time windows and the distance separations are defined in the method in order to minimize the effects of RFID coverage uncertainty. The power cost model is defined and incorporated into the method to minimize energy consumption and to maximize association performance. The proposed method computes the power cost using the range of the outermost position for possible single association and group associations at every sampling time. An RFID reader is activated with the proper coverage range when the power cost for the current time is lower than the power cost for the next time sample. The simplicity of the power cost model relieves the problematic combinatorial comparisons in multiple object cases. The performance comparison simulation with the minimum and maximum energy consumption shows that the proposed method achieves fast single associations with less energy consumption. Finally, the realistic comparison simulation with the fixed range RFID readers demonstrates that the proposed method outperforms the fixed ranges in terms of single association rate and energy consumption.

Ever-changing endoscopic treatment for early gastric cancer:Yesterday-today-tomorrow

引用

World Journal of Gastroenterology 2014年第37期20卷 13273-13283页

作者： Mi-Young Kim Jun-Hyung cho joo Young cho Digestive Disease Center Soonchunhyang University Hospital

Endoscopic resection has been an optimal treatment for selected patients with early gastric cancer(EGC) based on advances in endoscopic instruments and techniques. As endoscopic submucosal dissection(ESD) has been widely used for treatment of EGC along with expanding ESD indication, concerns have been asked to achieve curative resection for EGC while guaranteeing precise prediction of lymph node metastasis(LNM). Recently, new techniques including ESD or endoscopic full-thickness resection combined with sentinel node navigation enable minimal tumor resection and a laparoscopic lymphadenectomy in cases of EGC with high risk of LNM. This review covers the development and challenges of endoscopic treatment for EGC. Moreover, a new microscopic imaging and endoscopic techniques for precise endoscopic diagnosis and minimally invasive treatment of EGC are introduced.

Experimental and Modeling Studies on the Chemical Vapor Infiltration with Respect to the Effects of Thermal Gradient and Other Operating Parameters

引用

Journal of Wuhan University of Technology(Materials Science) 2018年第3期33卷 525-532页

作者： kyung Do joo Do Hoon Kim Gui Yung Chung Department of Chemical Engineering Hong Ik University

Effects of operating parameters in the thermal gradient chemical vapor infiltration of propane such as thermal gradient, diffusion, infiltrations time, and concentration of propane were studied by focusing on the visualizations of the intrinsic effects of these parameters. A uniform deposition in the preform was obtained with a gradually increasing temperature along the gas flow. The uniformity of deposition through the preform got improved with increasing deposition time. Results of numerical modeling estimated the experimental data very well when the pre-exponential factor of the overall rate of carbon deposition from propane reported by Vaidyaraman[1] was multiplied by 4. The average density of a preform increased by about 3 times from 0.38 to 1.15 g/cm3 after 60 hr deposition with a thermal gradient under the conditions of 3% propane in nitrogen and 840 to 900 ℃.
