( Yu Ho Lee ),( Yang-gyun Kim ),( Sang-ho Lee ),( Ju-young Moon ),( Kyung-hwan Jeong ),( Tae-won Lee ),( Chun-gyoo Ihm ) 대한신장학회 2014 Kidney Research and Clinical Practice Vol.33 No.3

Background: Urinary kidney injury molecule-1 (KIM-1) is an early and sensitivebiomarker of acute kidney injury, but it is unclear if it is a biomarker of chronicglomerulonephritis. We evaluated whether urinary KIM-1 levels in patients withimmunoglobulin A (IgA) nephropathy can be a marker to reflect clinicopathologicalseverity and predict the prognosis. Methods: We measured urinary KIM-1 levels in 40 patients (15 males; mean age36.6712.9 years) with IgA nephropathy and 10 healthy people (5 males; mean age37.379.6 years) as controls. The correlation of urinary KIM-1 levels with patients’clinical parameters, histological grades, and follow-up data were analyzed using themodified H. S. Lee grading system and tubulointerstitial change scores. Results: Urinary KIM-1 levels were higher in patients with IgA nephropathy thanhealthy controls (P¼0.001). Univariate and multivariate regression analyses showedthat urinary KIM-1 levels had a direct correlation with H. S. Lee grade andtubulointerstitial inflammation (P¼0.004 and P¼0.011, respectively). Conclusion: In patients with IgA nephropathy, urinary KIM-1 has a significantcorrelation with histopathologic severity.

The objective of this study was to evaluate the quality characteristics of sun-dried Hanwoo beef jerky added with Salicornia herbacea (SH). Sliced Hanwoo beef shank were marinated and sun-dried at 28-30oC, relative humidity (RH) 30-35% for 3.5 h. The physicochemical and microbiological traits of the Hanwoo beef jerky were analyzed during the aerobically packaged storage at 25oC. The water activities of beef jerky with 0.5% and 1.0% SH were lower than those of the control at 0 d (p

간경변 환자에서 Oro-cecal Transit Time의 측정

원경준,이준,변유미,조민근,조주연,서정균,김영대,박찬국,김만우 朝鮮大學校 附設 醫學硏究所 2008 The Medical Journal of Chosun University Vol.33 No.2

Background: Neurotransmitter like substances in the gut have been proposed to contribute to the overall portal systemic encephalopathy (PSE). The source of the ammonia in patients with PSE is mainly the small bowel, as a result of the conversion of glutamine in the diet to glutamate and ammonia. PSE is highly responsive to changes in diet, to antibiotic therapy and to ingestion of nondigestible disaccharides such as lactulose. This study was performed to evaluate the relationship between PSE and oro-cecal transit time. In addition, performed to evaluate the effect of severity, cause, complications of liver cirrhosis on oro-cecal transit time. Methods: Between August 2006 and February 2007, 48 cirrhotic patients consecutively was enrolled in study their oro-cecal transit time after informed consent was obtained. A non-invasive hydrogen breath test was used to study oro-cecal transit time (OCTT). Result: The OCTT were delayed in cirrhotic patients with PSE compared without PSE (123.3 ± 42.7 min vs 170.0 ± 58.3 min, p<0.05). OCTT tended to prolongate further as the damage in the liver got worse, nevertheless the result was statistically meaningless (p<0.111). Neither presence of ascites or cause of PSE had any influence on gastrointestinal transit. Conclusions: Cirrhotic patients with PSE have more delayed OCTT than without PSE. Further research is needed to find out the relationship between OCTT and severity of liver cirrhosis.

A Method for Identification of Harmful Video Images Using a 2-Dimensional Projection Map

Kim, Chang-Geun,Kim, Soung-Gyun,Kim, Hyun-Ju The Korea Institute of Information and Commucation 2013 Journal of information and communication convergen Vol.11 No.1

This paper proposes a method for identification of harmful video images based on the degree of harmfulness in the video content. To extract harmful candidate frames from the video effectively, we used a video color extraction method applying a projection map. The procedure for identifying the harmful video has five steps, first, extract the I-frames from the video and map them onto projection map. Next, calculate the similarity and select the potentially harmful, then identify the harmful images by comparing the similarity measurement value. The method estimates similarity between the extracted frames and normative images using the critical value of the projection map. Based on our experimental test, we propose how the harmful candidate frames are extracted and compared with normative images. The various experimental data proved that the image identification method based on the 2-dimensional projection map is superior to using the color histogram technique in harmful image detection performance.

Kim, Sang Gyun,Ju, Myung Jong,Choi, In Taek,Choi, Won Seok,Kim, Hwan Kyu Korean Society of Photoscience 2014 Rapid communication in photoscience Vol.3 No.1

N-doped anatase $TiO_2$ nanoparticles were prepared by the sol-gel process followed by a hydrothermal treatment and successfully used as the photoanodes in organic dye-sensitized solar cells (DSSCs). As expected, the power conversion efficiency (PCE) of 8.44% was obtained for the NKX2677/HC-A-sensitized DSSC based on the 30 mol% N-doped $TiO_2$ photoanode, which was an improvement of 23% relative to that of the DSSC based on the NKX2677/DCA.

Serine-arginine-rich nuclear protein LUC7L plays an important role in the regulation of myogenesis in mice. In the present study, we isolated and characterized the Korean rose bitterling Rhodeus uyekii Luc7l cDNA, designated RuLuc7l. The RuLuc7l cDNA is 1,688 bp long and encodes a 364-amino-acid polypeptide containing serine/arginine-rich region at the C-terminus. The deduced RuLuc7l protein has high amino acid identity (71-97%) with those of other species including human. Phylogenetic analysis revealed that RuLUC7L clustered with fish LUC7L proteins. The expression of RuLuc7l mRNA was high in the brain, kidney, and stomach of Korean rose bitterling. Expression of the RuLuc7l mRNA was detected from 1 day post-fertilization (dpf) and moderately increased until 21 dpf during the early development. Further investigations are required to elucidate the functional role of RuLUC7L in myogenesis in R. uyekii.

Shewanella sp. Ke75 Esterase with Specificity for p-nitorphenyl Butyrate: Gene Cloning and Characterization

Kim, Young-Ok,Park, In-Suk,Kim, Hyung-Kwoun,Nam, Bo-Hye,Kong, Hee Jeong,Kim, Woo-Jin,Kim, Dong-Gyun,Kim, Bong-Seok,Jee, Young-Ju,Song, Jung-Hun,Lee, Sang-Jun The Korean Society for Applied Biological Chemistr 2013 Applied Biological Chemistry (Appl Biol Chem) Vol.56 No.1

A bacterial strain that produces a cold-adapted esterase was isolated from tidal flats and identified as Shewanella sp. Ke75. In the present study, the corresponding gene was cloned using the shotgun method. The amino acid sequence deduced from the nucleotide sequence (957 bp) corresponded to a protein of 318 amino acid residues with a calculated molecular weight of 34875 Da. The esterase showed 68 and 57% identities with the putative esterases of Shewanella amazonensis SB2B and Colwellia psychrerythraea 34H, respectively. The esterase contained a putative leader sequence, as well as the conserved catalytic triad (Ser, His, Asp), consensus pentapeptide GXSXG, and oxyanion hole sequence (HG). The protein Ke75 was produced in both soluble and insoluble forms when Escherichia coli cells harboring the gene were cultured at $30^{\circ}C$. The enzyme showed specificity for C4 (butyrate) as a substrate, with little activity toward the other p-nitrophenyl esters tested. The optimum pH and temperature for enzyme activity were pH 9.0 and $30^{\circ}C$, respectively. Relative activity remained up to 60% even at $5^{\circ}C$ with an activation energy of 6.29 kcal/mol, which indicated that it was a cold-adapted enzyme. Enzyme activity was enhanced in the presence of $Mn^{2+}$ ions, but inhibited by $Cd^{2+}$, $Cu^{2+}$, $Hg^{2+}$, and $Zn^{2+}$ ions.

Ju Il Kim,Min Kwon,Si Hyeock Lee,Yong Gyun Kim,Jin Kyung Choi,Jong Wook Lee 한국응용곤충학회 2013 한국응용곤충학회 학술대회논문집 Vol.2013 No.04

The Diadegma fenestrale is known as parasitoid on potato tuber moth, Phthorimaea operculella and diamondback moth, Plutella xylostella. The Diadegma genus is reported to have symbiotic virus, ichnovirus, D. fenestrale Ichnovirus (DfIV) was identified from this species which is a first report. DfIV showed typical ichnovirus shape with two membranes surrounding the virus capsid. To identify DfIV genes, whole genome sequencing based on GS-FLX was conducted using purified total DfIV genomic DNA extracted from D. fenestrale calyx. About sixty ORFs were analyzed and several typical ichnovirus gene families were detected such as cys-motif, repeat element, vinnexin and vankyrin. Present study was focused on the gene expression patterns in two different lepidopteran hosts.
