  • Event-specific PCR detection methods are the primary trend in genetically modified (GM) plant detection owing to their high specificity based on the flanking sequence of the exogenous integrant. Therefore, this study describes a real-time PCR system for event-specific GM canola GT73, consisting of a set of primers, TaqMan probe, and single target standard plasmid. For the specific detection of GT73 canola, the 3'-integration junction sequence between the host plant DNA and the integrated specific border was targeted. To validate the proposed method, test samples of 0, 1, 3, 5, and 10% GT73 canola were quantified. The method was also assayed with 15 different plants, and no amplification signal was observed in a real-time PCR assay with any of the species tested, other than GT73 canola.

  • A multiplex polymerase chain reaction (PCR) method was developed to simultaneously detect three varieties of genetically modified (GM) canola. The construct-specific primers were used to distinguish the following three varieties of GM canola; GT73, MS8xRF3, and T45, using multiplex PCR. The FatA (fatty acyl-ACP thioesterase) gene was used as an endogenous canola reference gene in the PCR detection. The primer pair Canendo-FIR containing a 105 bp amplicon was used to amplify the FatA gene and no amplified product was observed in any of the 15 different plants used as templates. The GT73-KHUF1/R1 primer recognized the 3'-flanking region of GT73, resulting in an amplicon of 125 bp. The Barstar-F1/MS8xRF3-R primer recognized the junction region of bars tar and the NOS terminator introduced into MS8xRF3, resulting in a 162 bp amplicon, and the T45-F2/R2 primer recognized the junction region of PAT and the 35S terminator introduced into T45, resulting in an amplicon of 186 bp. This multiplex PCR allowed for the detection of construct-specific targets in a genomic DNA mixture of up to 1% GM canola containing GT73, MS8xRF3, and T45.

  • Effect of stripping solutions on the Duolite GT-73 chelating resin for ten elements, Ag(I), Al(III), Ca(II), Cd(II), Cu(II), Fe(II), Hg(II), Mn(II), Pb(II), and Zn(II), was investigated. Relation between affinities of the metal ions and solubility products of metal sulfides was studied. The smaller the solubility product of metal sulfideis, the larger the affinitie with the ionsis. The ions which have the solubility products larger than $10^{-23}$ could be effectively desorbed with nitric acid. Complexation with chloride ion enhanced the desorption efficiencies of the ions having moderately strong affinity with the resin. The ions which have very strong affinity by the chelating resin can be desorbed by complextion with thiourea and hydrochloric acid.

  • In this research, the characteristics of SOFC/GT (Solid Oxide Fuel Cell/Gas Turbine) system temperature, stack power and system efficiency for flow rates of air, CH4 and water supplied to SOFC stack have been investigated. The temperature of the gas supplied to cathode and anode of SOFC stack in the SOFC/GT system are maintained by utilizing exhaust gas without the addition of external heat source. As a result, within the scope of this study, temperatures of gas supplied to cathode and anode of SOFC stack were maintained at 1000 (K) by utilizing the exhaust gas of the SOFC/GT system without the addition of external heat source. The system efficiency is increased with increase of air flow rate supplied to the stack and with decrease of $CH_4$ flow rate supplied to the stack. In addition, it can be found that the flow rate of the exhaust gas supplied to the turbine had a significant effect on the system efficiency. And the efficiencies of SOFC stack and SOFC/GT system depending upon various operating conditions of the SOFC/GT system is 51~57% and 57~73%, respectively.

  • Background: Many studies have investigated the association between the MDM2 promoter SNP309 T/G polymorphism and liver cancer risk, but inconsistencies make drawwing definitive conclusions difficult. Methods: We therefore searched main databases for articles relating MDM2 SNP309 T/G polymorphism to risk of liver cancer in humans and estimated summary odds ratio (OR) with 95% confidence intervals (95% CI) to assess the possible association in a meta-analysis. Results: The main analysis revealed no significant heterogeneity, and the pooled ORs of fixed-effects were all significant (for G versus T, OR = 1.59, 95% CI 1.42-1.78; for GG versus TT, OR = 2.45, 95% CI 1.93-3.12; for GT versus TT, OR = 1.70, 95% CI 1.38-2.09; for GG versus GT, OR = 1.49, 95% CI 1.24-1.79; for GG and GT versus TT, OR = 1.95, 95% CI 1.61-2.38; for GG versus TT and GT, OR = 1.73, 95% CI 1.46-2.07). Subgroup analyses by ethnicity and sensitivity analyses both showed associations to remain significant. Conclusion: The present meta-analysis of available data showed a significant association between the MDM2 SNP309 T/G polymorphism and liver cancer risk, the MDM2 SNP309 G allele contributing to increased risk in both Asians and Caucasians in a graded, dose-dependent fashion.

  • Objectives : The aim of this study was to evaluate effects of herbal medicine and other associated factors for abnormal liver function tests(especially total bilirubin, AST, ALT, and ${\gamma}GT$) levels in outpatients at an oriental medical clinic. Methods : A cross-sectional study based on clinical records was conducted on 1,871 patients at one Oriental medical clinic in Seoul, Korea. 504 patients received a liver function tests for screening and 497 patients ranging from the age of 4 to 74 were chosen for the study. Patients with basal liver disease or DM were excluded during the screening process. Patients were classified into case(abnormal) and control(normal) groups by normal liver function test references. Results and Conclusions : In this study, 33.0% of the patients were females, and 67.0% were males. The mean age was $34.7{\pm}11.9$ years old. The mean total protein value was $6.78{\pm}0.66g/dL$(male $6.79{\pm}0.61$, female $6.76{\pm}0.76$), albumin $3.89{\pm}0.50g/dL$(male $3.94{\pm}0.47$, female $3.81{\pm}0.54$), total bilirubin $0.51{\pm}0.35mg/dL$(male $0.54{\pm}0.39$, female $0.45{\pm}0.23$), AST $23.31{\pm}18.22U/L$(male $26.37{\pm}20.73$, female $17.09{\pm}8.72$), ALT $33.49{\pm}36.36U/L$(male $40.56{\pm}41.77$, female $19.13{\pm}12.64$), LDH $258.07{\pm}74.84mg/dL$(male $263.68{\pm}73.77$, female $246.70{\pm}75.92$), and ${\gamma}GT$ $39.64{\pm}59.16U/L$(male $50.15{\pm}69.43$, female $17.83{\pm}8.36$). The percentage of abnormal total bilirubin levels(>1.0) in these patients was 2.6%, abnormal AST levels(>39m, >29f) 8.5%, ALT levels(>47m, >32f) 18.8%, and ${\gamma}GT$ (>50m, >40f) 19.9%.

  • Purpose: The aim of this study was to compare short-term results from use of the direct anterior approach (DAA) and the conventional posterolateral approach (PLA) in performance of bipolar hemiarthroplasty for treatment of femoral intertrochanteric fractures in elderly patients. Materials and Methods: A retrospective review of 100 patients with intertrochanteric fractures who underwent bipolar hemiarthroplasty was conducted. The PLA was used in 50 cases from 2016 to 2019; since that time we have used the DAA in 50 cases from 2019 to 2021. Measurements of mean operative time, blood loss, hospitalization period, and ambulation status, greater trochanter (GT) migration and stem subsidence were performed. And the incidence of complications was examined. Results: Operative time was 73.60±14.56 minutes in the PLA group and 79.80±8.89 minutes in the DAA group (P<0.05). However, after experiencing 20 cases using DAA, there was no statistically difference in operative time between two groups (P=0.331). Blood loss was 380.76±180.67 mL in the PLA group and 318.14± 138.51 mL in the DAA group (P<0.05). The hospitalization was 23.76±11.89 days in the PLA group and 21.45 ±4.18 days in the DAA group (P=0.207). In both groups, there were no progressive GT migration, intraoperative fractures or dislocations, although there was one case of infection in the PLA group. Conclusion: Although use of the DAA in performance of bipolar hemiarthroplasty required slightly more time in the beginning compared with the PLA, the DAA may well be an alternative, safe surgical technique as a muscle preserving procedure in elderly patients with intertrochanteric fractures.

  • A calculation method on performance impact of the controllable operations parameter such as GT inlet filter ${\Delta}P$, compressor efficiency, and condenser pressure was devised to achieve best performance of combined cycle power plant with the on-line performance monitoring system. This method calculates the performance impact on the deviation between 'Expected' values and 'Actual' values. Controllable parameter targets are determined based on achievable performance given existing equipments and control conditions.
