  • The goal of this dissertation is to analyze various Romantic styles appearing in modern fashion based upon the 'Difference' theory developed by Gilles Deleuze. A new framework for analyzing the changes of dress style based upon the 'Difference' theory derived from Deleuze's theory and from his interpretations of paintings was developed. The characteristics that represent 'difference' in change of dress style are deformation and hybridization. They are derived from the Deleuze's interpretations of 'difference' represented in the paintings by Bacon. The aesthetic values of the Romantic style in the 19th century dress are subordination, sensuality, and maternity. And the formative characteristics of the Romantic style dress are suppression of body, fixed form, volume, and ornamentation. The formative characteristics of the Romantic style that have appeared since 1980s is analyzed according to deformation and hybridization and the results are as follows: first, deformation caused by exaggeration or emphasis in the modern Romantic fashion creates changeability of the form, destruction of the 19th century style, volume, and ornamentation. Second, hybridization by combining heterogeneous characteristic between times and genders (for example, the 19th century and modern times or masculinity and femininity) frees body from the dress and changes the dress silhouettes and ornamentation. Thus totally new and different Romantic style is created. The Romantic style in modern fashion changed into the appropriate style to the modern society under various conditions such as designer's will, postmodernism, changes of femininity and technology. It can be said that this is an example of the Deleuze's 'becoming' theory.

  • Total genomic DNA library of Serratia marcescens was prepared by inserting Sau3AI partial digesting fragments(above 5 kb) into the dephosphorylated BamHl site of pUC19. In primary screening, two colonies were selected by observing the halo around E. coli transformants grown on the swollen colloidal chitin media. Secondary screening was performed by soaking two colonies with a few drops of 4-methylumbelleliferryl N-acetyl-$\beta$-D-glucocosaminide(4-MuNGlcNAc). As 4-MuNGlcNAc is a specific, fluorogenic substrate for chitinase, the positive clones produce light fluorescence by the exposure under the long wave U.V. light(360 nm). From genomic DNA library derived from pUC19, we have isolated two different chitinase clones, pCH1(11.0Kb) and pCH2(7.5Kb), which show completely different restriction map to each other. The cross-hybridization of pCH1EA and pCH2 have not revealed any hybridization signals to each other.

  • A 35-year-old man with infertility was referred for chromosomal analysis. In routine cytogenetic analysis, the patient was seen to have additional material of unknown origin on the terminal region of the short arm of chromosome 4. To determine the origin of the unknown material, we carried out high-resolution banding, comparative genomic hybridization (CGH), and FISH. CGH showed a gain of signal on the region of $4q32{\rightarrow}q35$. FISH using whole chromosome painting and subtelomeric region probes for chromosome 4 confirmed the aberrant chromosome as an intrachromosomal insertion duplication of $4q32{\rightarrow}q35$. Duplication often leads to some phenotypic abnormalities; however, our patient showed an almost normal phenotype except for congenital dysfunction in spermatogenesis.

  • Mammals have 3 pairs of major salivary glands i.e., the parotid, submandibular, and sublingual glands. Saliva secretion of these glands is modulated by taste perception. Salivary glands are composed mainly of acinar and ductal cells. Primary saliva is secreted by acinar cells and modified during ductal flow. Recently, of the murine 35 bitter taste receptors, Tas2r108 was expressed at highest levels in the submandibular gland by qPCR. Further, Tas2r108-transfected cells respond to a range of bitter compounds, such as denatonium, quinine, colchicine, diphenidol, caffeine and dapson. The objective of the present study was to characterize the expression of Tas2r108 mRNA in acinar and/or ductal cells of the submandibular gland using in situ hybridization (ISH). Male 42-60 days old DBA2 mice were used in the study. Messenger RNAs were extracted from the submandibular gland for generating digoxigenin (DIG) labeled-cRNA probes. These probes were transcribed in anti-sense and sense orientation using T7 RNA polymerase. Dot blot hybridization was performed using DIG labeled-cRNA probes, in order to estimate integrity and optimal diluting concentration of these probes. Subsequently, ISH was performed on murine submandibular gland to detect Tas2r108 mRNA. Dot blot hybridization data demonstrated that Tas2r108 DIG labeled-cRNA anti-sense probes specifically detected Tas2r108 cDNA. ISH results showed that the anti-sense probes labeled acinar and ductal cells in the submandibular gland, whereas no staining was visible in sense controls. Interestingly, the Tas2r108 expression levels were higher in acinar than ductal cells. These results suggested that Tas2r108 might be more associated with primary saliva secretion than with ductal modification of saliva composition.

  • The purpose of this study was to establish a rapid, reliable diagnostic method detecting Encephalomyocarditis virus(EMCV) RNA in formalin-fixed, paraffin-embedded tissues of EMCV naturally infected pigs by cDNA probe of EMC $K_3$, the EMCV strain isolated from Korea. Using a biotin-labelled nick translated probe for the cDNA marker. We made up for some defects of radiolabeled method. In sits hybridization(ISH) technique, differently from the other nucleic acid hybridization methods, is able to detect the virus genome specifically in the state of the intact shapes of cells and/or tissues. We succeeded in performing the experiment to detect the EMCV within 1~2 hours using the $MicroProbe^{TM}$ capaillary action system. In this study, we observed highly specific positive signals of red color by staining the paraffin-embedded tissue sections of naturally EMCV-infected pig organs or tissues, including brain, heart, kidney and lacrimal gland with the Fast Red TR salt/Naphtol phosphate chromogen. The results suggested that this ISH method is considered as a highly sensitive and reliable tool for molecular biologic diagnosis of the EMC viral disease.

  • To make the genomic DNA probe of Theileria sergenti, the merozoites were purified from bovine erythrocytes. The infected erythrocytes were lysed by Aeromonas hydrophila(Ah-1) hemolysin, and the parasites were isolated by ultracentrifugation on a Percoll discontinuous density gradient. For construction of a T sergenti genomic DNA library, T sergenti DNA was digested with Pstl and the fragments were ligated into the PstI site of pUC19 before transformation of Escherichia coli JM83. Out of thousands of transformants obtained by transformation of E coli JM83 with the genomic library, three plasmids were chosen. The sizes of the inserted DNAs were 2.9kb(2.4kb and 0.5kb) in pKTS1, 4.3kb in pKTS2 and 1.5kb in pKTS3, respectively. The DNA fragments used as probe KTS1(2.4kb), KTS2(4.3kb) and KTS3(1.5kb) were labeled digoxigenin-11-dUTP for the Southern hybridization. In Southern hybridization, all of the probes(KTS1, KTS2 and KTS3) reacted specifically to T sergenti DNA, but not to bovine leucocyte DNA. In order to find out the sensitivities of the digoxigenin-11-dUTP-labeled KTS1 and KTS3 as the probes, purified merozoite DNA and bovine DNA (control) were checked by dot blot hybridization with the probes. Both of the probes, KTS1 and KTS3, detected as minimum amount of 975pg of the T sergenti DNA, but not bovine DNA even to 500ng.

  • We have developed SH (shear horizontal) surface acoustic wave (SAW) sensors for detection of the immobilization and hybridization of DNA (deoxyribonucleic acid) on the gold coated delay line of transverse SAW devices. The experiments of DNA immobilization and hybridization were performed with 15-mer oligonucleotides (probe and complementary target DNA). The sensor consists of twin SAW delay line oscillators operating at 100 MHz fabricated on $36^{\circ}$ rotated Y-cut $LiTaO_3$ piezoelectric single crystals. The relative change in the frequency of the two oscillators was monitored to detect the hybridization between target DNA and immobilized probe DNA in pH 7.4 PBS (phosphate buffered saline) solution. The measurement results showed a good response of the sensor to the mass loading effects of the DNA immobilization and hybridization with the sensitivity up to $1.55{\cal}ng/{\cal}ml/Hz$.

  • We observed the structure of phenylalanine ammonia-lyase gene (PAL) which is one of the best studied plant defense-related genes responding to pathogen infection by producing suberin, lignin, and phytoalexins. In tomato, at least 5 different genetic loci have been identified by genomic southern blot hybridization and nucleotide sequence analyses of partially cloned gene fragments (Lee et al. 1992). However, our results suggest that two other isoforms designated as PAL X1 and PAL X2 are located on the chromosome in tomato plant. Furthermore, the preliminary results obtained from southern blot hybridization analyses of subcloned fragment digested with several restriction endonuclease indicated that PAL X1 and PAL X2 clones contain at least two copies of PAL gene and partial nucleotide sequence analyses of each subcloned fragment with the same primer taken from known nucleotide sequence of PAL5 gene indicated that they are located side by side on the same chromosome.

  • E. coli has long been widely used as a host system for the manufacture of recombinant proteins intended for human therapeutic use. When considering the impurities to be eliminated during the downstream process, residual host cell DNA is a major safety concern. The presence of residual E. coli host cell DNA in the final products is typically determined using a conventional slot blot hybridization assay or total DNA Threshold assay. However, both the former and latter methods are time consuming, expensive, and relatively insensitive. This study thus attempted to develop a more sensitive real-time PCR assay for the specific detection of residual E. coli DNA. This novel method was then compared with the slot blot hybridization assay and total DNA Threshold assay in order to determine its effectiveness and overall capabilities. The novel approach involved the selection of a specific primer pair for amplification of the E. coli 16S rRNA gene in an effort to improve sensitivity, whereas the E. coli host cell DNA quantification took place through the use of SYBR Green I. The detection limit of the real-time PCR assay, under these optimized conditions, was calculated to be 0.042 pg genomic DNA, which was much higher than those of both the slot blot hybridization assay and total DNA Threshold assay, where the detection limits were 2.42 and 3.73 pg genomic DNA, respectively. Hence, the real-time PCR assay can be said to be more reproducible, more accurate, and more precise than either the slot blot hybridization assay or total DNA Threshold assay. The real-time PCR assay may thus be a promising new tool for the quantitative detection and clearance validation of residual E. coli host cell DNA during the manufacturingprocess for recombinant therapeutics.

  • Salmonella species are the most prevalent etiologic agents of food-borne acute gastroenteritis. Direct isolation of bacteria from the contaminated food, stool and animal tissues has been used for the diagnosis of salmonellosis routinely. However, isolation of bacteria is time consuming work and not so highly sensitive. In recent years, improved methods of polymerization chain reaction(PCR) and probe hybridization technique have led to the developement of diagnostic assays which employ to detect various human and animal pathogenic bacteria. In this study, we have performed the polymerization chain reaction to detect Salmonella pullorum from tissues and stool samples of chickens with two specific primers, ST5 and ST8C. The target DNA fragment of PhoE gene was successfully amplified from liver, spleen, pancreas, heart, lung, ovary, oviduct and feces samples. The amplified DNA fragments were hybridized with Salmonella typhymurium TA3000 PhoE probe by Southern hybridization. The PCR to amplify the PhoE gene was highly rapid and sensitive method to detect Salmonella pullorum from tissues and stool samples.
