천정미(Chun Jung Mee),박미령(Park Mi Ryung) 경성대학교 인문과학연구소 2005 인문학논총 Vol.10 No.-
The purpose of this paper is to find some suggestions to the field of education from John Dewey's educational theory. Dewey emphasized that the aim of education is the growth of intelligence of a learner. The curriculum should be derived from the experience and related to the present experience of learner. The method of education progress into the five levels with the process of reflective thinking. To the field of education, Dewey's educational theory suggests the followings. First, the aim of education should be the cultivation of learner's ability to adapt to the society and the cultivation of the thinking ability as his growth. Second, the curriculum should be the materials which help a thinking process and give rise to thought to a learner. Third, the method of education should be a method of cultivation of the thinking ability of a learner.

Background: We developed an assay to measure DNA-incorporated 6-thioguanine (DNA-TG) and validated its clinical applicability in Korean pediatric patients with acute lymphoblastic leukemia (ALL) in order to improve individualized thiopurine treatment and reduce the life-threatening cytotoxicity. Methods: The DNA-TG assay was developed based on liquid chromatography-tandem mass spectrometry, with isotope-labeled TG-d3 and guanine-d3 as internal standards. This method was applied to 257 samples of pediatric ALL patients. The DNA-TG level was compared with erythrocyte TG nucleotide (RBC-TGN) level in relation to the TPMT and NUDT15 genotypes, which affect thiopurine metabolism, using Spearman’s rank test and repeated measure ANOVA. Results: For DNA-TG quantification, a linearity range of 10.0-5,000.0 fmol TG/μg DNA; bias for accuracy of –10.4% –3.5%; coefficient of variation for intra- and inter-day precision of 3.4% and 5.8% at 80 fmol TG/μg DNA and of 4.9% and 5.3% at 800 fmol TG/μg DNA, respectively; and recovery of 85.7%-116.2% were achieved without matrix effects or carry-over. The median DNA-TG level in the 257 samples was 106.0 fmol TG/μg DNA (interquartile range, 75.8-150.9). There was a strong correlation between DNA-TG and RBC-TGN levels (ρ=0.68, P<0.0001). The DNA-TG/RBC-TGN ratio was significantly higher in NUDT15 intermediate metabolizers (*1/*2 and *1/*3) than in patients with wild-type alleles (P<0.0001). Conclusions: This simple and sensitive method for measuring DNA-TG level can improve therapeutic drug monitoring for thiopurine treatment.

<P>Anal squamous cell carcinoma (ASCC), either with human papillomavirus (+) or (-), is a neoplastic disease with frequent recurrence and metastasis. To characterize ASCC genomes, we attempted to disclose novel alterations of ASCC genomes and other genetic features including mutation signatures. We performed whole-exome sequencing and copy number alteration (CNA) profiling for 8 ASCC samples from 6 patients (2 cases with primary and recurrent/metastatic tumors). We found known ASCC mutations (TP53, CDKN2A, and PIK3CA) and CNAs (gains on 3q and 19q and losses on 11q and 13q). In addition, we discovered novel mutations in HRAS and ARID1A and CNAs (gain on 8q and losses 5q, 9p, 10q, and 19p) that had not been reported in ASCCs. We identified 4 signature patterns of the mutations (signatures 1 and 2 with deamination of 5-methyl-cytosin, signature 3 with APOBEC, and signature 4 with mismatch repair) in the ASCCs. Although signatures 1 to 3 have been detected in other SCCs, signature 4 was first identified in ASCCs. In addition, we first found that ASCCs harbored chromothripsis, copy-neutral losses of heterozygosity, and focal amplification of KLF5 super-enhancer. Analyses of primary and recurrent/metastatic pair genomes revealed that driver events in development and progression of ASCC might not be uniform. Our data indicate that ASCCs may have similar mutation and CNA profiles to other SCCs, but that there are unique genomic features of ASCCs as well. Our data may provide useful information for ASCC pathogenesis and for developing clinical strategies for ASCC. (C) 2018 Elsevier Inc. All rights reserved.</P>

<P><B>Purpose</B></P><P>This study investigated population pharmacokinetics of paroxetine, and then performed an integrated analysis of exposure and clinical outcome using population pharmacokinetic parameter estimates in depressed patients treated with paroxetine.</P><P><B>Patients and methods</B></P><P>A total of 271 therapeutic drug monitoring (TDM) data were retrospectively collected from 127 psychiatric outpatients. A population nonlinear mixed-effects modeling approach was used to describe serum concentrations of paroxetine. For 83 patients with major depressive disorder, the treatment response rate and the incidence of adverse drug reaction (ADR) were characterized by logistic regression using daily dose or area under the concentration–time curve (AUC) estimated from the final model as a potential exposure predictor.</P><P><B>Results</B></P><P>One compartment model was developed. The apparent clearance of paroxetine was affected by age as well as daily dose administered at steady-state. Overall treatment response rate was 72%, and the incidence of ADR was 30%. The logistic regression showed that exposure predictors were not associated with treatment response or ADR in the range of dose commonly used in routine practice. However, the incidence of ADR increased with the increase of daily dose or AUC for the patients with multiple concentrations.</P><P><B>Conclusion</B></P><P>In depressed patients treated with paroxetine, TDM may be of limited value for individualization of treatment.</P>

Understanding the behavior of transgenes introduced into oocyte or embryos is essential for evaluating the methodologies for transgenic animal production. To date, many studies have reported the production of transgenic pig embryos with, however, low efficiency in environment of blastocyst production. The aim of present study was to determine the expression and duration of transgene transferred by intracytoplasmic sperm injection-mediated gene transfer (ICSI-MGT). Embryos obtained from the ICSI-MGT procedure were analysed for the expression of GFP and then for the transmission of the transgene. Briefly, fresh spermatozoa were bound to exogenous DNA after treatment by Triton X-100 and Lipofectin. When ICSI-MGT was performed using sperm heads with tails removed, the yield of blastocyst (25.3%), treated with Lipofectin (18.8%) and Triton X-100 (19.2%) were observed. Treatments of Lipofectin or Triton X-100 did not further improve the rates of blastocysts. Moreover, the apoptosis rates of embryos were obtained from the control and LIpofectin groups (8.7%, 9.7%, respectively), but were significantly higher in the Triton X-100 group (13.0%). Our results demonstrated that ICSI-MGT caused minimal damage to oocytes that could develop to full term. Moreover, the embryos derived by ICSI-MGT have shown prolonged exogenous DNA expression during preimplantation stage in vivo. However, more efforts will be required to improve the procedures of both sperm treatments cause of high frequency of mosaicisms.
