Microsomal epoxide hydrolase (mEH)은 epoxide형 중간대사물을 해독화하는 효소이다. 본 실험실에서는 thiazole 또는 pyrazine을 rat에 투여할 때 mEH mRNA수준이 증가되고 mEH가 유도증가한다는 것을 밝힌바 있다(Carcinogenesis, Kim et al, 1993). 본 연구에서는 Thiazole처리를 한 rat의 간 microsome 분획으로 부터 DEAE-cellulose column chromatography를 이용하여 mEH를 순수분리하였고, 이를 SDS-PAGE분석 및 N 말단 amino acid 서열분석으로 확인하였다. Pyrazine처리를 한 rat의 간 microsome분획에서는 mEH와 더불어 이와... -

Acidovorax citrulli (Ac) is the causal agent of bacterial fruit blotch (BFB) in watermelon, a disease that poses a serious threat to watermelon production. Because of the lack of resistant cultivars against BFB, virulence factors or mechanisms need to be elucidated to control the disease. Glycerol-3-phosphate dehydrogenase is the enzyme involved in glycerol production from glucose during glycolysis. In this study, we report the functions of a putative glycerol-3-phosphate dehydrogenase in Ac... -

Pathogenesis-related proteins play multiple roles in plant development and biotic and abiotic stress tolerance. Here, we characterize a rice defense related gene named “jasmonic acid inducible pathogenesis-related class 10” (JIOsPR10) to gain an insight into its functional properties. Semi-quantitative RT-PCR analysis showed up-regulation of JIOsPR10 under salt and drought stress conditions. Constitutive over-expression JIOsPR10 in rice promoted shoot and root development in... -
Involvement of the OsMKK4-OsMPK1 Cascade and its Downstream Transcription Factor OsWRKY53 in the Wounding Response in Rice

한국식물병리학회 The Plant Pathology Journal 2014, 30권 2호 7 168-177 (10 pages)
Plant has possessed diverse stress signals from outside and maintained its fitness. Out of such plant responses, it is well known that mitogen-activated protein kinase (MAPK) cascade plays important role in wounding and pathogen attack in most dicot plants. However, little is understood about its role in wounding response for the economically important monocot rice plant. In this study, therefore, the involvement of MAPK was investigated to understand the wounding signaling pathway in rice. The... -

3D integration 기술 특히 W2W integration 기술은 전자산업의 디바이스 scaling 문제를 해결하고 고성능화 소형화 추세에 맞춘 가장 핵심적인 기술 방향이다. 그러나 W2W integration 기술은 현재 가격과 생산수율의 장애를 가지고 있고, 이를 해결하기 위해서 웨이퍼 매칭, 리던던시, 다이 면적 축소, 배선 층 수 축소와 같은 디자인 연구들이 진행되고 있다. W2W integration 기술이 대량생산으로 연결되기 위해서는 우선적으로 웨이퍼 본딩, 실리콘연삭, TSV 배선 공정의 최적화가 이루어져야 하겠지만, 가격을 포함한 생산수율을... -

본 논문에서는 $0.35{mu}m$ Bipolar-CMOS-DMOS(BCD)공정으로 설계한 스마트 파워 IC 내의 가드링 코너 영역에서 발생하는 비정상적인 정전기 불량을 관측하고 이를 분석하였다. 칩내에서 래치업(Latch-up)방지를 위한 고전압 소자의 가드링에 연결되어 있는 Vcc단과 Vss 사이에 존재하는 기생 다이오드에서 발생한 과도한 전류 과밀 현상으로 정전기 내성 평가에서 Machine Model(MM)에서는 200V를 만족하지 못하는 불량이 발생하였다. Optical Beam Induced Resistance Charge(OBIRCH)와 Scanning Electronic Microscope(SEM)을 사용하여...
